Definitions

  • the present invention relates to a domestic dishwasher.
  • the pamphlets DE 20 2009 004 771 U1 and DE 10 2012 107 993 A1 each disclose a slide/pivot mechanism set up for this purpose.
  • This includes a shelf, for example a lower basket, which is held in a linearly displaceable manner on a guide rail.
  • the guide rail is articulated in a pivotable manner on a body of the domestic dishwasher via two pivoting arms.
  • U.S. 2008/0129168 A1 a sliding/pivoting mechanism for a shelf, in particular a lower basket, of a domestic dishwasher.
  • the shelf is held in a linearly displaceable manner by means of a closed frame on two guide rails arranged on both sides, and the frame is pivoted on a body of the domestic dishwasher along a circular path via two swivel arms arranged on each side, so that the shelf can be moved between a lower, pushed-in position within the domestic dishwasher and a upper extended position is movable outside the domestic dishwasher.
  • a household dishwasher is provided with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device.
  • the at least one loading level is linearly displaceable along the at least one guide rail between a first position below and a second position below the same. In the first position below, the at least one loading level is arranged below and inside the body. In the second position below, the at least one loading level is arranged below and at least partially outside the body.
  • the at least one link arm pivotally holds the at least one guide rail on the body for moving the loading plane between the second position below and a third position above it. In the third position, the at least one loading level is arranged at the top and at least partially outside the body.
  • the guide device guides the at least one link arm along a guide path which at least partially deviates from a circular path.
  • the guide track points in the extension direction.
  • the at least one loading plane can be shifted from the second position at the bottom to the third position at the top, with an increasing incline at least in certain areas.
  • the guide device has a link guide formed on the body and a link element attached to the link arm, which engages in the link guide, with the link guide preferably being formed as a slot and the link element as a pin.
  • the track is partially or fully non-circular. Due to the guide device, the loading level can be controlled in such a way that it remains closer to the body with its center of gravity on its way up between the second position below and the third position above.
  • the at least one loading plane at least partially does not follow a part-circle movement of the link arm, for example not a quarter-circle movement known from the prior art, but deviates from it, in particular upwards and towards the body. It is thus possible for the at least one loading level in particular to be pulled completely out of the body ("full extension") without the domestic dishwasher tipping over.
  • the body can include a rinsing container.
  • the at least one link arm can be articulated on the washing compartment, in particular on a fitting of the same.
  • the loading level can very generally be a shelf or holder, in particular for crockery or cutlery.
  • the loading level is preferably a crockery basket or a cutlery drawer.
  • the at least one loading level is particularly preferably a lower crockery basket.
  • the at least one link arm in the first position below and in the second position below the at least one loading plane can be oriented vertically and in the third position above the at least one loading plane can be oriented horizontally.
  • “Vertical” and “horizontal” here also include deviations from the vertical or horizontal of up to 15°, preferably less than 10° and more preferably less than 5°.
  • the guide track can therefore have different geometric profiles; it preferably has an increasing incline, at least in its initial area. As a result, the at least one loading level is guided particularly closely to the body.
  • the link guide or the slot can be formed in a side wall of the washing compartment.
  • the link guide can have an increasing incline or the shape of half a parabola, at least in some areas, with other forms of the link guide also being possible.
  • the guideway has the shape of half a parabola, the apex of which lies on a longitudinal center axis of the at least one link arm in the first position below and/or in the second position below the at least one loading plane.
  • this form of a guide track contributes in a simple way to a particularly narrow guidance of the at least one loading level on the body on its way up from the second position at the bottom to the third position at the top (and vice versa).
  • the link arm is set up for a rotary and linear relative movement with respect to its pivot point on the body.
  • the link arm has a slot into which a pin arranged on the body engages.
  • the pin thus serves as an articulation point for the link arm on the body, so that a relative rotational movement is made possible.
  • a linear relative movement is also possible due to the elongated hole, with the link arm being able to be displaced linearly with the elongated hole in relation to the pin.
  • a first end position of the pin in the slot of the first position below and/or the second position below the at least one loading level and an opposite end position of the pin in the slot of the third position above the at least one loading level can be assigned.
  • a household dishwasher is provided with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device.
  • the at least one loading level is linearly displaceable along the at least one guide rail between a first position below and a second position below the same. In the first position, the at least one loading level is arranged below and inside the body. In the second position below, the at least one loading level is arranged below and at least partially outside the body.
  • the at least one link arm pivotally holds the at least one guide rail on the body for moving the loading plane between the second position below and a third position above it.
  • the at least one loading level is arranged in the third position above and at least partially outside the body.
  • the guide device is set up to guide the at least one loading level between the second position at the bottom and the third position at the top on a circular path.
  • the circular path deviates from that on which the at least one guide rail can be moved.
  • the guide lever is articulated at one end on the body and at its other end can be brought into pivotal engagement with the at least one loading level when the same is linearly displaced from the first position at the bottom to the second position at the bottom.
  • the guide lever has an articulation point on the body, which is below and/or in front of the articulation point of the at least one guide lever in the extension direction, in which the at least one loading level can be linearly displaced from the first position at the bottom to the second position at the bottom.
  • the respective circular paths can intersect.
  • the guide device prevents the loading plane from moving between the second position at the bottom and the third position at the top on a circular path, the center point of which coincides with the pivot point of the at least one link arm on the body. Rather, the guide lever ensures that the at least one loading level is pulled back along the guide rail when the at least one loading level is moved from its second position at the bottom to its third position at the top.
  • This measure also means that the at least one loading level is guided closer to the body than is the case with conventional solutions.
  • the center of gravity of the at least one loading level is moved less far forward, so that the risk of the household dishwasher tipping over is avoided.
  • the guide device preferably has a guide lever.
  • the guide lever is designed in particular as an elongate element, for example as a plastic or metal profile part.
  • the at least one loading plane If the at least one loading plane is moved linearly from the first position at the bottom to the second position at the bottom, it automatically engages the other end of the guide lever. This engagement is pivotable, so that in the engaged state, the loading plane can only be pivoted about the pivot point of the guide lever at its one end on the body. A linear one In contrast, shifting the at least one loading level is excluded in the engaged state.
  • the at least one loading level can thus be guided suitably close to the body.
  • the guide device comprises a blocking piece or a blocking counterpart.
  • the other end of the guide lever has the locking piece and the at least one loading plane has the locking counterpiece, the locking piece and the locking counterpiece releasing a linear displacement of the at least one loading plane relative to the guide lever in a released state and blocking the linear displacement in a locked state of the same.
  • the locking piece or the locking counterpart is rotatable about an axis of rotation in the other of the locking piece and the locking counterpart for adjusting them between the locking state and the unlocking state.
  • the axis of rotation is preferably coaxial with a pivot axis about which one end of the guide lever is articulated in a pivotable manner on the at least one loading plane.
  • the locking piece and the locking counterpart are engaged with each other such that the linear displacement of the loading plane is locked.
  • the locking counterpart can engage behind the locking piece (or vice versa) in the locked direction.
  • the locking counterpart can extend around the locking piece on the outside at least in sections (or vice versa).
  • the release state disengagement of the lock piece and the lock counterpart in the direction of linear displacement is permitted.
  • the release state can thus refer to a state in which, for example, the blocking piece is still arranged in the blocking counterpart, but can be moved out of it.
  • the release state may refer to a state in which the locking piece and the locking counterpart are spaced from each other.
  • the axis of rotation is preferably coaxial with the pivot axis results in a simple mechanism for preventing simultaneous pivoting and linear displacement of the at least one loading plane relative to the guide lever.
  • this can prevent the at least one loading level, after it has been brought into pivotal engagement with the other end of the guide lever in the pull-out direction and a pivoting of the at least one loading level from the second position at the bottom to the third position at the top has begun, moved back against the pull-out direction, i.e. into the washing tub.
  • a shifting back is preferably excluded until the at least one loading plane has been pivoted back completely from its third position at the top to the second position at the bottom. Only then is the linear displacement of the at least one loading level back into the washing compartment released.
  • a simple mechanism results from the fact that the rotational movement of the locking piece and locking counterpart to each other in the present solution is a result of the movement of the at least one loading level upwards from the second position below to the third position above, with the at least one loading level relative to the Guide lever pivoted. This means that the rotary movement and the pivoting movement take place at the same time, with the pivoting movement being the cause of the rotary movement.

Die vorliegende Erfindung betrifft eine Haushaltsgeschirrspülmaschine.The present invention relates to a domestic dishwasher.

Die Be- und Entladung eines Unterkorbs einer Haushaltsgeschirrspülmaschine wird von Benutzern oft als unbequem empfunden, da dies ein Arbeiten in gebeugter Halterung erfordert. Daher sind aus dem Stand der Technik verschiedene Mechaniken bekannt geworden, um den Unterkorb aus einer unteren Position desselben innerhalb des Spülbehälters der Haushaltsgeschirrspülmaschine in eine obere Position außerhalb des Spülbehälters anzuheben.Loading and unloading a lower basket of a household dishwasher is often found uncomfortable by users, since this requires working in a bent position. Various mechanisms have therefore become known from the prior art in order to raise the lower basket from a lower position thereof within the washing compartment of the domestic dishwasher to an upper position outside the washing compartment.

Die Druckschriften DE 20 2009 004 771 U1 und DE 10 2012 107 993 A1 offenbaren jeweils eine zu diesem Zweck eingerichtete Schiebe-/Schwenkmechanik. Diese umfasst eine Ablage, beispielsweise einen Unterkorb, welcher an einer Führungsschiene linear verschiebbar gehalten ist. Die Führungsschiene ist über zwei Schwenkarme an einem Korpus der Haushaltsgeschirrspülmaschine schwenkbar angelenkt.The pamphlets DE 20 2009 004 771 U1 and DE 10 2012 107 993 A1 each disclose a slide/pivot mechanism set up for this purpose. This includes a shelf, for example a lower basket, which is held in a linearly displaceable manner on a guide rail. The guide rail is articulated in a pivotable manner on a body of the domestic dishwasher via two pivoting arms.

Weiterhin offenbart die Druckschrift US 2008/0129168 A1 eine Schiebe-/Schwenkmechanik für eine Ablage, insbesondere einen Unterkorb, einer Haushaltsgeschirrspülmaschine. Die Ablage ist mittels eines geschlossenen Rahmens an zwei beidseitig angeordneten Führungsschienen linear verschiebbar gehalten und der Rahmen ist über jeweils zwei beidseitig angeordnete Schwenkarme an einem Korpus der Haushaltsgeschirrspülmaschine entlang einer Kreisbahn schwenkbar angelenkt, so dass die Ablage zwischen einer unteren eingeschobenen Position innerhalb der Haushaltsgeschirrspülmaschine und einer oberen ausgezogenen Position außerhalb der Haushaltsgeschirrspülmaschine bewegbar ist.Furthermore, the reference discloses U.S. 2008/0129168 A1 a sliding/pivoting mechanism for a shelf, in particular a lower basket, of a domestic dishwasher. The shelf is held in a linearly displaceable manner by means of a closed frame on two guide rails arranged on both sides, and the frame is pivoted on a body of the domestic dishwasher along a circular path via two swivel arms arranged on each side, so that the shelf can be moved between a lower, pushed-in position within the domestic dishwasher and a upper extended position is movable outside the domestic dishwasher.

Allgemein stellt sich bei derartigen Schiebe-/Schwenkmechaniken das Problem, dass der Schwerpunkt des Unterkorbs derart weit vor den Korpus verschwenkt wird, dass die gesamte Haushaltsgeschirrspülmaschine nach vorne kippt. Teilweise wird versucht, dieses Problem dadurch zu umgehen, dass kein Vollauszug für den Unterkorb vorgesehen wird. Dadurch ergeben sich jedoch wiederum ergonomische Nachteile bei der Be- und Entladung des Unterkorbs.In general, such sliding/pivoting mechanisms have the problem that the center of gravity of the lower basket is pivoted so far in front of the body that the entire domestic dishwasher tips forward. Some attempts are made to circumvent this problem by not providing a full extension for the lower basket. However, this in turn results in ergonomic disadvantages when loading and unloading the lower basket.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte Haushaltsgeschirrspülmaschine zur Verfügung zu stellen.Against this background, it is an object of the present invention to provide an improved domestic dishwasher.

Demgemäß wird eine Haushaltsgeschirrspülmaschine mit einem Korpus, zumindest einer Beladungsebene, zumindest einer Führungsschiene, zumindest einem Lenkerarm und einer Führungseinrichtung bereitgestellt. Die zumindest eine Beladungsebene ist entlang der zumindest einen Führungsschiene zwischen einer ersten Position unten und einer zweiten Position unten derselben linear verlagerbar. In der ersten Position unten ist die zumindest eine Beladungsebene unten und innerhalb des Korpus angeordnet. In der zweiten Position unten ist die zumindest eine Beladungsebene unten und zumindest teilweise außerhalb des Korpus angeordnet. Der zumindest eine Lenkerarm hält die zumindest eine Führungsschiene für ein Bewegen der Beladungsebene zwischen der zweiten Position unten und einer dritten Position oben derselben schwenkbar an dem Korpus. Die zumindest eine Beladungsebene ist in der dritten Position oben und zumindest teilweise außerhalb des Korpus angeordnet. Die Führungseinrichtung führt den zumindest einen Lenkerarm entlang einer Führungsbahn, welche zumindest teilweise von einer Kreisbahn abweicht. Die Führungsbahn weist in Auszugsrichtung. In welcher die zumindest eine Beladungsebene aus der zweiten Position unten in die dritte Position oben verlagerbar ist, zumindest bereichsweise eine zunehmende Steigung auf. Die Führungseinrichtung weist eine an dem Korpus ausgebildete Kulissenführung und ein an dem Lenkerarm angebrachtes Kulissenelement auf, welches in die Kulissenführung eingreift, wobei bevorzugt die Kulissenführung als Schlitz und das Kulissenelement als Stift ausgebildet sind.Accordingly, a household dishwasher is provided with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device. The at least one loading level is linearly displaceable along the at least one guide rail between a first position below and a second position below the same. In the first position below, the at least one loading level is arranged below and inside the body. In the second position below, the at least one loading level is arranged below and at least partially outside the body. The at least one link arm pivotally holds the at least one guide rail on the body for moving the loading plane between the second position below and a third position above it. In the third position, the at least one loading level is arranged at the top and at least partially outside the body. The guide device guides the at least one link arm along a guide path which at least partially deviates from a circular path. The guide track points in the extension direction. In which the at least one loading plane can be shifted from the second position at the bottom to the third position at the top, with an increasing incline at least in certain areas. The guide device has a link guide formed on the body and a link element attached to the link arm, which engages in the link guide, with the link guide preferably being formed as a slot and the link element as a pin.

Mit anderen Worten ist die Führungsbahn teilweise oder vollständig nicht-kreisförmig. Aufgrund der Führungseinrichtung kann die Beladungsebene so gesteuert werden, dass diese auf ihrem Weg nach oben zwischen der zweiten Position unten und der dritten Position oben mit ihrem Schwerpunkt enger an dem Korpus bleibt. Die zumindest eine Beladungsebene folgt dabei zumindest teilweise nicht einer Teilkreisbewegung des Lenkerarms, beispielsweise nicht einer aus dem Stand der Technik bekannten Viertelkreisbewegung, sondern weicht von dieser insbesondere nach oben und zu dem Korpus hin von dieser ab. Somit ist es möglich, die zumindest eine Beladungsebene insbesondere vollständig aus dem Korpus herauszuziehen ("Vollauszug"), ohne dass es zu einem Kippen der Haushaltsgeschirrspülmaschine kommt.In other words, the track is partially or fully non-circular. Due to the guide device, the loading level can be controlled in such a way that it remains closer to the body with its center of gravity on its way up between the second position below and the third position above. The at least one loading plane at least partially does not follow a part-circle movement of the link arm, for example not a quarter-circle movement known from the prior art, but deviates from it, in particular upwards and towards the body. It is thus possible for the at least one loading level in particular to be pulled completely out of the body ("full extension") without the domestic dishwasher tipping over.

Der Korpus kann insbesondere einen Spülbehälter umfassen. Der zumindest eine Lenkerarm kann an dem Spülbehälter, insbesondere an einem Beschlag desselben, angelenkt sein.In particular, the body can include a rinsing container. The at least one link arm can be articulated on the washing compartment, in particular on a fitting of the same.

Bei der Beladungsebene kann es sich ganz allgemein um eine Ablage oder Aufnahme insbesondere für Geschirr oder Besteck handeln. Bevorzugt handelt es sich bei der Beladungsebene um einen Geschirrkorb oder eine Besteckschublade. Besonders bevorzugt ist die zumindest eine Beladungsebene ein unterer Geschirrkorb.The loading level can very generally be a shelf or holder, in particular for crockery or cutlery. The loading level is preferably a crockery basket or a cutlery drawer. The at least one loading level is particularly preferably a lower crockery basket.

"Unten" und "oben" ist vorliegend dahingehend zu verstehen, dass die dritte Position oben der Beladungsebene oberhalb der ersten Position unten und der zweiten Position unten der Beladungsebene vorgesehen ist."Below" and "above" is to be understood here to mean that the third position above the loading level is provided above the first position below and the second position below the loading level.

Insbesondere kann der zumindest eine Lenkerarm in der ersten Position unten und in der zweiten Position unten der zumindest einen Beladungsebene vertikal und in der dritten Position oben der zumindest einen Beladungsebene horizontal ausgerichtet sein. "Vertikal" und "horizontal" umfassen hier auch Abweichungen von der Vertikalen beziehungsweise Horizontalen um bis zu 15°, bevorzugt weniger 10° und weiter bevorzugt weniger 5°.In particular, the at least one link arm in the first position below and in the second position below the at least one loading plane can be oriented vertically and in the third position above the at least one loading plane can be oriented horizontally. “Vertical” and “horizontal” here also include deviations from the vertical or horizontal of up to 15°, preferably less than 10° and more preferably less than 5°.

Die Führungsbahn kann also unterschiedliche geometrische Verläufe aufweisen; vorzugsweise weist sie zumindest in ihrem Anfangsbereich eine zunehmende Steigung auf. Dadurch wird die zumindest eine Beladungsebene besonders eng an dem Korpus geführt.The guide track can therefore have different geometric profiles; it preferably has an increasing incline, at least in its initial area. As a result, the at least one loading level is guided particularly closely to the body.

Beispielsweise kann die Kulissenführung beziehungsweise der Schlitz in einer Spülbehälterseitenwand ausgebildet sein. Entsprechend den vorstehenden Ausführungsbeispielen kann die Kulissenführung zumindest bereichsweise eine zunehmende Steigung oder die Form einer halben Parabel aufweisen, wobei auch andere Formen der Kulissenführung möglich sind.For example, the link guide or the slot can be formed in a side wall of the washing compartment. Corresponding to the above exemplary embodiments, the link guide can have an increasing incline or the shape of half a parabola, at least in some areas, with other forms of the link guide also being possible.

Gemäß einer Ausführungsform weist die Führungsbahn die Form einer halben Parabel auf, deren Scheitelpunkt auf einer Längsmittelachse des zumindest einen Lenkerarms in der ersten Position unten und/oder in der zweiten Position unten der zumindest einen Beladungsebene liegt.According to one embodiment, the guideway has the shape of half a parabola, the apex of which lies on a longitudinal center axis of the at least one link arm in the first position below and/or in the second position below the at least one loading plane.

Es hat sich gezeigt, dass diese Form einer Führungsbahn auf einfache Weise zu einer besonders engen Führung der zumindest einen Beladungsebene an dem Korpus auf ihrem Weg nach oben aus der zweiten Position unten in die dritte Position oben (und umgekehrt) beiträgt.It has been shown that this form of a guide track contributes in a simple way to a particularly narrow guidance of the at least one loading level on the body on its way up from the second position at the bottom to the third position at the top (and vice versa).

Gemäß einer weiteren Ausführungsform ist der Lenkerarm für eine rotatorische und lineare Relativbewegung bezüglich seines Anlenkpunkts an dem Korpus eingerichtet. Insbesondere weist der Lenkerarm ein Langloch auf, in welches ein an dem Korpus angeordneter Zapfen greift.According to a further embodiment, the link arm is set up for a rotary and linear relative movement with respect to its pivot point on the body. In particular, the link arm has a slot into which a pin arranged on the body engages.

Der Zapfen dient also als Anlenkpunkt des Lenkerarms an dem Korpus, so dass eine rotatorische Relativbewegung ermöglicht wird. Gleichzeitig ist jedoch auch eine lineare Relativbewegung aufgrund des Langlochs möglich, wobei sich der Lenkerarm mit dem Langloch gegenüber dem Zapfen linear verschieben lässt. Dabei kann eine erste Endlage des Zapfens in dem Langloch der ersten Position unten und/oder der zweiten Position unten der zumindest einen Beladungsebene und eine gegenüberliegende Endlage des Zapfens in dem Langloch der dritten Position oben der zumindest einen Beladungsebene zugeordnet sein.The pin thus serves as an articulation point for the link arm on the body, so that a relative rotational movement is made possible. At the same time, however, a linear relative movement is also possible due to the elongated hole, with the link arm being able to be displaced linearly with the elongated hole in relation to the pin. A first end position of the pin in the slot of the first position below and/or the second position below the at least one loading level and an opposite end position of the pin in the slot of the third position above the at least one loading level can be assigned.

Weiterhin wird eine Haushaltsgeschirrspülmaschine mit einem Korpus, zumindest einer Beladungsebene, zumindest einer Führungsschiene, zumindest einem Lenkerarm und einer Führungseinrichtung bereitgestellt. Die zumindest eine Beladungsebene ist entlang der zumindest einen Führungsschiene zwischen einer ersten Position unten und einer zweiten Position unten derselben linear verlagerbar. Die zumindest eine Beladungsebene ist in der ersten Position unten und innerhalb des Korpus angeordnet. In der zweiten Position unten ist die zumindest eine Beladungsebene unten und zumindest teilweise außerhalb des Korpus angeordnet. Der zumindest eine Lenkerarm hält die zumindest eine Führungsschiene für ein Bewegen der Beladungsebene zwischen der zweiten Position unten und einer dritten Position oben derselben schwenkbar an dem Korpus. Die zumindest eine Beladungsebene ist in der dritten Position oben und zumindest teilweise außerhalb des Korpus angeordnet. Die Führungseinrichtung ist dazu eingerichtet, die zumindest eine Beladungsebene zwischen der zweiten Position unten und der dritten Position oben auf einer Kreisbahn zu führen. Die Kreisbahn weicht von derjenigen ab, auf welcher die zumindest eine Führungsschiene bewegbar ist. Der Führungshebel ist an seinem einen Ende an dem Korpus angelenkt und an seinem anderen Ende mit der zumindest einen Beladungsebene bei einem linearen Verlagern derselben aus der ersten Position unten in die zweite Position unten schwenkbar in Eingriff bringbar. Der Führungshebel weist einen Anlenkpunkt an dem Korpus auf, welcher unter und/oder in Auszugsrichtung, in welcher die zumindest eine Beladungsebene aus der ersten Position unten in die zweite Position unten linear verlagerbar ist, vor dem Anlenkpunkt des zumindest einen Führungshebels liegt.Furthermore, a household dishwasher is provided with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device. The at least one loading level is linearly displaceable along the at least one guide rail between a first position below and a second position below the same. In the first position, the at least one loading level is arranged below and inside the body. In the second position below, the at least one loading level is arranged below and at least partially outside the body. The at least one link arm pivotally holds the at least one guide rail on the body for moving the loading plane between the second position below and a third position above it. The at least one loading level is arranged in the third position above and at least partially outside the body. The guide device is set up to guide the at least one loading level between the second position at the bottom and the third position at the top on a circular path. The circular path deviates from that on which the at least one guide rail can be moved. The guide lever is articulated at one end on the body and at its other end can be brought into pivotal engagement with the at least one loading level when the same is linearly displaced from the first position at the bottom to the second position at the bottom. The guide lever has an articulation point on the body, which is below and/or in front of the articulation point of the at least one guide lever in the extension direction, in which the at least one loading level can be linearly displaced from the first position at the bottom to the second position at the bottom.

Insbesondere können sich die jeweiligen Kreisbahnen schneiden. Die Führungseinrichtung verhindert, dass sich die Beladungsebene zwischen der zweiten Position unten und dritten Position oben auf einer Kreisbahn bewegt, deren Mittelpunkt mit dem Anlenkpunkt des zumindest einen Lenkerarms an dem Korpus zusammenfällt. Vielmehr sorgt der Führungshebel dafür, dass die zumindest eine Beladungsebene entlang der Führungsschiene zurückgezogen wird, wenn sich die zumindest eine Beladungsebene aus ihrer zweiten Position unten in ihre dritte Position oben bewegt wird. Auch durch diese Maßnahme wird die zumindest eine Beladungsebene näher an dem Korpus geführt, als dies bei herkömmlichen Lösungen der Fall ist. Entsprechend wird der Schwerpunkt der zumindest einen Beladungsebene weniger weit nach vorne bewegt, so dass die Gefahr eines Kippens der Haushaltsgeschirrspülmaschine vermieden wird.In particular, the respective circular paths can intersect. The guide device prevents the loading plane from moving between the second position at the bottom and the third position at the top on a circular path, the center point of which coincides with the pivot point of the at least one link arm on the body. Rather, the guide lever ensures that the at least one loading level is pulled back along the guide rail when the at least one loading level is moved from its second position at the bottom to its third position at the top. This measure also means that the at least one loading level is guided closer to the body than is the case with conventional solutions. Correspondingly, the center of gravity of the at least one loading level is moved less far forward, so that the risk of the household dishwasher tipping over is avoided.

Die Führungseinrichtung weist bevorzugt einen Führungshebel auf. Der Führungshebel ist insbesondere als längliches Element, beispielsweise als ein Kunststoff- oder Metallprofilteil ausgebildet.The guide device preferably has a guide lever. The guide lever is designed in particular as an elongate element, for example as a plastic or metal profile part.

Wird die zumindest eine Beladungsebene also aus der ersten Position unten in die zweite Position unten linear bewegt, so gelangt diese selbsttätig mit dem anderen Ende des Führungshebels in Eingriff. Dieser Eingriff ist schwenkbar ausgeführt, so dass in dem Eingriffszustand lediglich ein Verschwenken der Beladungsebene um den Anlenkpunkt des Führungshebels an dessen einem Ende an dem Korpus möglich ist. Ein lineares Verlagern der zumindest einen Beladungsebene ist in dem Eingriffszustand dagegen ausgeschlossen.If the at least one loading plane is moved linearly from the first position at the bottom to the second position at the bottom, it automatically engages the other end of the guide lever. This engagement is pivotable, so that in the engaged state, the loading plane can only be pivoted about the pivot point of the guide lever at its one end on the body. A linear one In contrast, shifting the at least one loading level is excluded in the engaged state.

Damit lässt sich die zumindest eine Beladungsebene geeignet nah an dem Korpus führen.The at least one loading level can thus be guided suitably close to the body.

Gemäß einer weiteren Ausführungsform umfasst die Führungseinrichtung ein Sperrstück oder ein Sperrgegenstück. Insbesondere weist das andere Ende des Führungshebels das Sperrstück und die zumindest eine Beladungsebene das Sperrgegenstück auf, wobei das Sperrstück und das Sperrgegenstück in einem Freigabezustand derselben ein lineares Verlagern der zumindest einen Beladungsebene relativ zu dem Führungshebel freigeben und in einem Sperrzustand derselben das lineare Verlagern sperren. Das Sperrstück oder das Sperrgegenstück ist für ein Verstellen dieser zwischen dem Sperrzustand und dem Freigabezustand um eine Drehachse in dem jeweils anderen von dem Sperrstück und dem Sperrgegenstück drehbar. Bevorzugt ist die Drehachse mit einer Schwenkachse achsgleich, um die das eine Ende des Führungshebels an der zumindest einen Beladungsebene schwenkbar angelenkt ist.According to a further embodiment, the guide device comprises a blocking piece or a blocking counterpart. In particular, the other end of the guide lever has the locking piece and the at least one loading plane has the locking counterpiece, the locking piece and the locking counterpiece releasing a linear displacement of the at least one loading plane relative to the guide lever in a released state and blocking the linear displacement in a locked state of the same. The locking piece or the locking counterpart is rotatable about an axis of rotation in the other of the locking piece and the locking counterpart for adjusting them between the locking state and the unlocking state. The axis of rotation is preferably coaxial with a pivot axis about which one end of the guide lever is articulated in a pivotable manner on the at least one loading plane.

In dem Sperrzustand stehen das Sperrstück und das Sperrgegenstück miteinander derart in Eingriff, dass das lineare Verlagern der Beladungsebene gesperrt ist. Insbesondere kann das Sperrgegenstück das Sperrstück (oder umgekehrt) in der gesperrten Richtung hintergreifen. Beispielsweise kann sich dazu das Sperrgegenstück außen um das Sperrstück zumindest abschnittsweise herum erstrecken (oder umgekehrt). In dem Freigabezustand ist dagegen ein Außereingriffbringen des Sperrstücks und des Sperrgegenstücks in der Richtung des linearen Verlagerns freigegeben. Der Freigabezustand kann sich somit auf einen Zustand beziehen, in welchem beispielsweise das Sperrstück noch in dem Sperrgegenstück angeordnet, jedoch aus diesem heraus bewegbar ist. Oder der Freigabezustand kann sich auf einen Zustand beziehen, in welchem das Sperrstück und das Sperrgegenstück voneinander beabstandet angeordnet sind.In the locked state, the locking piece and the locking counterpart are engaged with each other such that the linear displacement of the loading plane is locked. In particular, the locking counterpart can engage behind the locking piece (or vice versa) in the locked direction. For example, the locking counterpart can extend around the locking piece on the outside at least in sections (or vice versa). On the other hand, in the release state, disengagement of the lock piece and the lock counterpart in the direction of linear displacement is permitted. The release state can thus refer to a state in which, for example, the blocking piece is still arranged in the blocking counterpart, but can be moved out of it. Or the release state may refer to a state in which the locking piece and the locking counterpart are spaced from each other.

Dadurch, dass bevorzugt die Drehachse mit der Schwenkachse achsgleich ist, ergibt sich ein einfacher Mechanismus, um ein gleichzeitiges Verschwenken und lineares Verlagern der zumindest einen Beladungsebene relativ zu dem Führungshebel zu verhindern. Insbesondere kann so verhindert werden, dass sich die zumindest eine Beladungsebene, nachdem sie in Auszugsrichtung mit dem anderen Ende des Führungshebels schwenkbar in Eingriff gebracht worden ist, und ein Verschwenken der zumindest einen Beladungsebene aus der zweiten Position unten in die dritte Position oben begonnen hat, entgegen der Auszugsrichtung, das heißt in den Spülbehälter hinein, zurückverlagert. Entsprechend ist bevorzugt ein solches Zurückverlagern solange ausgeschlossen, bis die zumindest eine Beladungsebene aus ihrer dritten Position oben wieder vollständig in die zweite Position unten zurückverschwenkt worden ist. Erst hiernach ist das lineare Zurückverlagern der zumindest einen Beladungsebene in den Spülbehälter freigegeben. Eine einfache Mechanik ergibt sich somit dadurch, dass die Drehbewegung von Sperrstück und Sperrgegenstück zueinander bei der vorliegenden Lösung ein Ergebnis der Bewegung der zumindest einen Beladungsebene nach oben aus der zweiten Position unten in die dritte Position oben ist, wobei die zumindest eine Beladungsebene relativ zu dem Führungshebel verschwenkt. Das heißt, die Drehbewegung und die Schwenkbewegung finden gleichzeitig statt, wobei die Schwenkbewegung Ursache für die Drehbewegung ist.The fact that the axis of rotation is preferably coaxial with the pivot axis results in a simple mechanism for preventing simultaneous pivoting and linear displacement of the at least one loading plane relative to the guide lever. In particular, this can prevent the at least one loading level, after it has been brought into pivotal engagement with the other end of the guide lever in the pull-out direction and a pivoting of the at least one loading level from the second position at the bottom to the third position at the top has begun, moved back against the pull-out direction, i.e. into the washing tub. Accordingly, such a shifting back is preferably excluded until the at least one loading plane has been pivoted back completely from its third position at the top to the second position at the bottom. Only then is the linear displacement of the at least one loading level back into the washing compartment released. A simple mechanism results from the fact that the rotational movement of the locking piece and locking counterpart to each other in the present solution is a result of the movement of the at least one loading level upwards from the second position below to the third position above, with the at least one loading level relative to the Guide lever pivoted. This means that the rotary movement and the pivoting movement take place at the same time, with the pivoting movement being the cause of the rotary movement.

Gemäß einer weiteren Ausführungsform weist das Sperrstück oder das Sperrgegenstück ein C-förmiges Element mit einer radialen Öffnung auf. Das jeweils andere von dem Sperrstück und dem Sperrgegenstück weist ein mittels der radialen Öffnung einführbares zapfenförmiges Element auf.According to a further embodiment, the locking piece or the locking counterpart has a C-shaped element with a radial opening. The respective other of the locking piece and the locking counterpart has a pin-shaped element that can be inserted by means of the radial opening.

Durch lineares Verlagern gelangt das zapfenförmige Element durch die radiale Öffnung in den von dem C-förmigen Element umschlossenen Raum. Durch relatives Verdrehen des Sperrstücks und des Sperrgegenstücks hintergreift das C-förmige Element das zapfenförmige Element entgegen der Auszugsrichtung, so dass ein Bewegen des zapfenförmigen Elements entgegen der Auszugsrichtung dann gesperrt ist.By linear displacement, the peg-shaped element passes through the radial opening into the space enclosed by the C-shaped element. By relative rotation of the blocking piece and the blocking counterpart, the C-shaped element engages behind the peg-shaped element counter to the pull-out direction, so that movement of the peg-shaped element counter to the pull-out direction is then blocked.

Der Führungshebel wird bevorzugt zumindest in der ersten Position unten und in der zweiten Position unten der zumindest einen Beladungsebene mittels eines Anschlags in Position gehalten. Der Anschlag kann an dem Korpus befestigt sein.The guide lever is preferably held in position at least in the first position below and in the second position below the at least one loading plane by means of a stop. The stop can be attached to the body.

Noch weiterhin wird eine Haushaltsgeschirrspülmaschine mit einem Korpus, zumindest einer Beladungsebene, zumindest einer Führungsschiene, zumindest einem Lenkerarm und einer Führungseinrichtung bereitgestellt. Die zumindest eine Beladungsebene ist entlang der zumindest einen Führungsschiene zwischen einer ersten Position unten und einer zweiten Position unten derselben linear verlagerbar. Die zumindest eine Beladungsebene ist in der ersten Position unten und innerhalb des Korpus und in der zweiten Position unten und zumindest teilweise außerhalb des Korpus angeordnet. Der zumindest eine Lenkerarm hält die zumindest eine Führungsschiene für ein Bewegen der Beladungsebene zwischen der zweiten Position unten und einer dritten Position oben derselben schwenkbar an dem Korpus. Die zumindest eine Beladungsebene ist in der dritten Position oben und zumindest teilweise außerhalb des Korpus angeordnet. Die Führungseinrichtung ist dazu eingerichtet, die zumindest eine Beladungsebene entlang einer Führungsbahn zu führen, welche von einer Kreisbahn abweicht. Die Führungseinrichtung weist eine an dem Korpus angeordnete, insbesondere gerade und/oder vertikale Führungsschiene und ein an der zumindest einen Beladungsebene angeordnetes Führungselement auf. Das Führungselement gelangt vorzugsweise mittels linearen Verlagerns der zumindest einen Beladungsebene aus der ersten Position unten in die zweite Position unten mit der Führungsschiene in Anlage. Alternativ oder zusätzlich ist vorzugsweise beim Bewegen der zumindest einen Beladungsebene zwischen der zweiten Position unten und der dritten Position oben das Führungselement entlang der Führungsschiene geführt.Furthermore, a household dishwasher is provided with a body, at least one loading level, at least one guide rail, at least one link arm and a guide device. The at least one loading level is linearly displaceable along the at least one guide rail between a first position below and a second position below the same. The at least one loading plane is arranged below and inside the body in the first position and below and at least partially outside the body in the second position. The at least one link arm pivotally holds the at least one guide rail on the body for moving the loading plane between the second position below and a third position above it. In the third position, the at least one loading level is arranged at the top and at least partially outside the body. The guide device is set up to guide the at least one loading plane along a guide path that deviates from a circular path. The guide device has an in particular straight and/or vertical guide rail arranged on the body and a guide element arranged on the at least one loading level. The guide element preferably comes into contact with the guide rail by linear displacement of the at least one loading plane from the first position at the bottom to the second position at the bottom. Alternatively or additionally, the guide element is preferably guided along the guide rail when the at least one loading level is moved between the second position below and the third position above.

Mit anderen Worten ist die Führungsbahn teilweise oder vollständig nicht-kreisförmig. Aufgrund der Führungseinrichtung kann die zumindest eine Beladungsebene beziehungsweise deren Schwerpunkt nah an dem Korpus zwischen ihrer zweiten Position unten und ihrer dritten Position oben geführt werden. Entsprechend kann ein Kippen der Haushaltsgeschirrspülmaschine vermieden werden.In other words, the track is partially or fully non-circular. Due to the guide device, the at least one loading level or its center of gravity can be guided close to the body between its second position at the bottom and its third position at the top. Accordingly, the domestic dishwasher can be prevented from tipping over.

Bevorzugt wird die zumindest eine Beladungsebene aus ihrer ersten Position unten in ihre zweite Position unten bewegt, woraufhin das Führungselement mit der Führungsschiene in Anlage gelangt. Bei der sich anschließenden Bewegung der zumindest einen Beladungsebene zwischen der zweiten Position unten und dritten Position oben wird das Führungselement entlang der Führungsschiene geführt und zieht dabei die zumindest eine Beladungsebene entlang der zumindest einen Führungsschiene entgegen der Auszugsrichtung zurück, wenn sich die zumindest eine Beladungsebene aus der zweiten Position unten in die dritte Position oben bewegt. Das Führungselement kann beispielsweise nur in der Auszugsrichtung gegen die Führungsschiene anliegen und entsprechend senkrecht dazu entlang dieser geführt werden. Zusätzlich kann die Führungsschiene als Kanal ausgebildet sein, in welchem das Führungselement in und entgegen der Auszugsrichtung fixiert ist, entsprechend ein lineares Verlagern des Führungselements in und entgegen der Auszugsrichtung gesperrt ist, während sich die zumindest eine Beladungsebene zwischen der zweiten Position unten und dritten Position oben bewegt.The at least one loading level is preferably moved from its first position below into its second position below, whereupon the guide element comes into contact with the guide rail. During the subsequent movement of the at least one loading level between the second position at the bottom and the third position at the top, the guide element is guided along the guide rail and pulls back the at least one loading level along the at least one guide rail in the opposite direction to the extension direction if the at least one loading level moves out of the second position down to third position up. The guide element can, for example, rest against the guide rail only in the extension direction and correspondingly perpendicular to it along this. In addition, the guide rail can be designed as a channel in which the guide element is fixed in and against the extension direction, correspondingly linear displacement of the guide element in and against the extension direction is blocked, while the at least one loading level is between the second position at the bottom and the third position at the top emotional.

Gemäß einer Ausführungsform verläuft die Führungsbahn gerade und/oder vertikal.According to one embodiment, the guideway runs straight and/or vertically.

Von "vertikal" sind hier auch Abweichungen von der Vertikalen um bis zu 30°, bevorzugt weniger 10° und weiter bevorzugt weniger 5° umfasst."Vertical" here also includes deviations from the vertical of up to 30°, preferably less than 10° and more preferably less than 5°.

Gemäß einer weiteren Ausführungsform ist das Führungselement als Rolle oder Gleitelement ausgebildet.According to a further embodiment, the guide element is designed as a roller or sliding element.

Damit kann das Führungselement geräuscharm und mit wenig Kraftaufwand bedienbar an der Führungsschiene geführt werden.In this way, the guide element can be guided on the guide rail with little noise and in an operable manner.

Gemäß einer weiteren Ausführungsform umfasst die Führungsschiene zwei parallele Wände, zwischen welche das Führungselement beim linearen Verlagern der zumindest einen Beladungsebene mittels einer Öffnung einführbar ist und/oder zwischen welche das Führungselement beim Bewegen der zumindest einen Beladungsebene zwischen der zweiten Position unten und der dritten Position oben geführt ist.According to a further embodiment, the guide rail comprises two parallel walls, between which the guide element can be inserted when the at least one loading plane is linearly displaced by means of an opening and/or between which the guide element can be inserted when the at least one loading plane is moved between the second position at the bottom and the third position at the top is led.

Entsprechend bilden die zwei parallelen Wände den zuvor erwähnten Kanal. Die Öffnung kann beispielsweise einfach dadurch gebildet sein, dass die in Auszugsrichtung vordere Wand der beiden parallelen Wände verkürzt ausgebildet ist und damit ein Bewegen des Führungselements in der Auszugsrichtung auf die andere parallele Wand freigibt. Steht das Führungselement dann in der Auszugsrichtung in Anlage mit der anderen Wand, so befindet sich das Führungselement direkt unterhalb der Öffnung zwischen den zwei parallelen Wänden, mittels derer sich das Führungselement zwischen die zwei parallelen Wände einführen lässt.Correspondingly, the two parallel walls form the aforementioned channel. The opening can, for example, be formed simply by shortening the front wall of the two parallel walls in the pull-out direction, thereby enabling movement of the guide element in the pull-out direction onto the other parallel wall. If the guide element is then in contact with the other wall in the pull-out direction, the guide element is located directly below the opening between the two parallel walls, by means of which the guide element can be inserted between the two parallel walls.

Die Fig. 1 zeigt eine schematische perspektivische Ansicht einer Haushaltsgeschirrspülmaschine 1. Die Haushaltsgeschirrspülmaschine 1 weist einen einen Spülbehälter 2 umfassenden Korpus auf, welcher durch eine Tür 3 wasserdicht verschließbar ist.The 1 shows a schematic perspective view of a household dishwasher 1. The household dishwasher 1 has a body which includes a washing compartment 2 and which can be closed watertight by a door 3.

Der Spülbehälter 2 und die Tür 3 können eine Spülkammer 4 zum Spülen von Spülgut bilden. Die Tür 3 ist in der Fig. 1 in ihrer geöffneten Stellung gezeigt. Durch Schwenken um eine an einem unteren Ende der Tür 3 vorgesehene Schwenkachse kann die Tür 3 geschlossen oder geöffnet werden.The washing container 2 and the door 3 can form a washing chamber 4 for washing items to be washed. Door 3 is in the 1 shown in their open position. The door 3 can be closed or opened by pivoting about a pivot axis provided at a lower end of the door 3 .

Der Spülbehälter 2 ist beispielsweise quaderförmig und kann einen Boden 5, eine dem Boden 5 gegenüberliegende Decke 6, eine der Tür 3 gegenüberliegende Rückwand 7 und zwei einander gegenüberliegende Seitenwände 8, 9 umfassen. Insbesondere die Seitenwände 8, 9 können aus Edelstahlblech gefertigt sein.The washing compartment 2 is cuboid, for example, and can comprise a floor 5, a cover 6 opposite the floor 5, a rear wall 7 opposite the door 3, and two side walls 8, 9 opposite one another. In particular, the side walls 8, 9 can be made of stainless steel sheet.

Die Haushaltsgeschirrspülmaschine 1 weist weiterhin zumindest eine Beladungsebene 10 auf. Die Beladungsebene 10 ist vorzugsweise eine Spülgutaufnahme der Haushaltsgeschirrspülmaschine 1. Insbesondere können mehrere Beladungsebenen 10 vorgesehen sein, wobei jeweils eine der mehreren Beladungsebenen 10 einen Unterkorb, einen Oberkorb oder eine Besteckschublade der Haushaltsgeschirrspülmaschine 1 sein kann. Die mehreren Beladungsebenen 10 sind vorzugsweise übereinander in dem Spülbehälter 2 angeordnet. Jede Beladungsebene 10 ist wahlweise in einer Einschubrichtung E (Pfeil) in den Spülbehälter 2 hinein oder in einer Auszugsrichtung A (Pfeil) aus diesem heraus verlagerbar. Hierzu ist bevorzugt zu beiden Seiten einer jeweiligen Beladungsebene 10 eine Schieneneinrichtung 11 vorgesehen.The household dishwasher 1 also has at least one loading level 10 . The loading level 10 is preferably a dishwashing receptacle of the domestic dishwasher 1. In particular, multiple loading levels 10 can be provided, one of the multiple loading levels 10 being a lower basket, an upper basket or a cutlery drawer of the domestic dishwasher 1. The multiple loading levels 10 are preferably arranged one above the other in the washing compartment 2 . Each loading level 10 can be moved either in a push-in direction E (arrow) into the washing compartment 2 or in a pull-out direction A (arrow) out of it. For this purpose, a rail device 11 is preferably provided on both sides of a respective loading level 10 .

Die Fig. 2 zeigt eine Ansicht II aus der Fig. 1 gemäß einer ersten Variante, wobei die Seitenwand 9 nicht gezeigt ist, so dass ein Blick auf die Seitenwand 8 sowie die davor liegende Spülkammer 4 freigegeben ist. Ferner ist in der Fig. 2 eine Beladungsebene 10 in Form eines unteren Geschirrkorbs gezeigt.The 2 shows a view II from the 1 According to a first variant, the side wall 9 is not shown, so that a view of the side wall 8 and the washing chamber 4 in front of it is released. Furthermore, in the 2 a loading level 10 is shown in the form of a lower dish rack.

Der Geschirrkorb 10 ist gegenüber einer Führungsschiene 12 der bereits im Zusammenhang mit der Fig. 1 genannten Schieneneinrichtung 11 linear verlagerbar. Dazu kann der Geschirrkorb 10 beispielsweise eine weitere Führungsschiene 13 umfassen, welche mittels nicht gezeigter Rollenlager sowie einer nicht gezeigten Laufschiene gegenüber der Führungsschiene 12 linear verlagerbar ist. Die Führungsschienen 12 und 13 bilden miteinander eine sogenannte Teleskopschiene. Alternativ könnte der Geschirrkorb 10 auch Laufrollen aufweisen, mittels derer er an der Führungsschiene 12 linear verschieblich gehalten ist.The crockery basket 10 is opposite a guide rail 12 which is already associated with the 1 mentioned rail device 11 linearly displaceable. For this purpose, the crockery basket 10 can comprise, for example, a further guide rail 13 which can be linearly displaced relative to the guide rail 12 by means of roller bearings (not shown) and a running rail (not shown). The guide rails 12 and 13 together form a so-called telescopic rail. Alternatively, the crockery basket 10 could also have rollers, by means of which it is held on the guide rail 12 in a linearly displaceable manner.

Der Geschirrkorb 10 weist eine erste, nicht gezeigte Position unten auf, in welcher er in der Einschubrichtung E (Pfeil) in die Spülkammer 4 eingeschoben und nahe oder in Anlage gegen die Rückwand 7 angeordnet ist. Ferner ist der Geschirrkorb 10 in der ersten Position unten in einem unteren Bereich der Spülkammer 4 nahe dem Boden angeordnet.The crockery basket 10 has a first position at the bottom (not shown), in which it is pushed into the washing chamber 4 in the insertion direction E (arrow) and is arranged close to or in contact with the rear wall 7 . Furthermore, in the first position, the dish rack 10 is arranged at the bottom in a lower region of the washing chamber 4 close to the floor.

Demgegenüber zeigt die Fig. 2 eine zweite Position unten des Geschirrkorbs 10, in welcher dieser in der Auszugsrichtung A (Pfeil) linear teilweise aus der Spülkammer 4 heraus verlagert ist. Der Geschirrkorb 10 könnte auch vollständig aus der Spülkammer 4 heraus verlagert werden (sogenannter Vollauszug). Diese Bewegung entspricht einer ausschließlich waagerechten Verschiebung des Geschirrkorbs 10. "Waagerecht" umfasst vorliegend auch Abweichungen von weniger ± 20°, bevorzugt weniger ± 10° und weiter bevorzugt ± 5°.In contrast, the 2 a second position at the bottom of the crockery basket 10, in which it is linearly partially displaced out of the washing chamber 4 in the pull-out direction A (arrow). The crockery basket 10 could also be moved completely out of the washing chamber 4 (so-called full extension). This movement corresponds to an exclusively horizontal displacement of the crockery basket 10. In the present case, "horizontal" also includes deviations of less than ±20°, preferably less than ±10° and more preferably ±5°.

An die zweite Position unten schließt sich nun eine in der Fig. 3 gezeigte dritte Position oben des Geschirrkorbs 10 an. In der dritten Position oben ist der Geschirrkorb 10 nach oben verschwenkt und außerhalb der Spülkammer 4 angeordnet. Zwecks Bewegung aus der zweiten Position unten in die dritte Position oben weist die Haushaltsgeschirrspülmaschine 1 gemäß dieser ersten Variante eine nachfolgend auf die Fig. 2, die Fig. 3 und die Fig. 4 Bezug nehmend beschriebene Mechanik auf.The second position below is now followed by one in the 3 shown third position above the dish rack 10 at. In the third position at the top, the crockery basket 10 is pivoted upwards and is arranged outside the washing chamber 4 . In order to move from the second position below to the third position above, the domestic dishwasher 1 according to this first variant has a subsequent to the 2 , the 3 and the 4 Referring to mechanics described.

Die Fig. 2 und die Fig. 3 zeigen jeweils eine Parallelogramm-Lenkeranordnung 14, welche beispielsweise zwei Lenkerarme 15, 16 umfasst. Die Lenkerarme 15, 16 sind jeweils - nachfolgend jedoch der Einfachheit halber nur für den Lenkerarm 15 näher erläutert - an der Seitenwand 8 an ihrem einen Ende an einem Anlenkpunkt 17 angelenkt. An ihrem anderen Ende sind die Lenkerarme 15, 16 an der Führungsschiene 12 an einem Anlenkpunkt 18 angelenkt.The 2 and the 3 each show a parallelogram linkage arrangement 14 which, for example, comprises two link arms 15, 16. The link arms 15, 16 are each - explained in more detail below for the sake of simplicity only for the link arm 15 - articulated on the side wall 8 at one end at a pivot point 17. at her At the other end, the link arms 15, 16 are articulated on the guide rail 12 at a pivot point 18.

Um den Geschirrkorb 10 aus der zweiten Position unten in die dritte Position oben zu bewegen, können die Lenkerarme 15, 16 um beispielsweise, wie gezeigt, 80° verschwenkt werden. Allerdings kann ein entsprechender maximaler Schwenkwinkel zwischen beispielsweise 60° und 90° betragen. In der zweiten Position unten (dies gilt im Übrigen auch für die nicht gezeigte, erste Position unten) können die Lenkerarme 15, 16, wie in der Fig. 2 gezeigt, vertikal ausgerichtet sein. Diese Lage nehmen die Lenkerarme 15, 16 insbesondere aufgrund der Wirkung der Schwerkraft ein.In order to move the crockery basket 10 from the second position at the bottom to the third position at the top, the link arms 15, 16 can be pivoted by 80°, for example, as shown. However, a corresponding maximum swivel angle can be between 60° and 90°, for example. In the second position below (this also applies to the first position, not shown, below), the control arms 15, 16, as in FIG 2 shown to be vertically aligned. The link arms 15, 16 assume this position, in particular due to the effect of gravity.

Der Geschirrkorb 10 kann in der zweiten Position unten relativ zu der Führungsschiene 12 linear unbeweglich fixiert sein, wozu ein entsprechender Arretiermechanismus vorgesehen sein kann. Um nun zu verhindern, dass sich der Geschirrkorb 10 beim Verschwenken der Lenkerarme 15, 16 zu weit vor, also in der Auszugsrichtung A, (Pfeil) dem Spülbehälter 2 bewegt und potentiell zu einem Verkippen der Haushaltsgeschirrspülmaschine 1 führt, ist eine Führungseinrichtung 19 vorgesehen. Die Führungseinrichtung 19 umfasst eine Kulissenführung 20 und ein Kulissenelement 21.In the second position, the crockery basket 10 can be fixed linearly immovably at the bottom relative to the guide rail 12, for which purpose a corresponding locking mechanism can be provided. In order to prevent the crockery basket 10 from moving too far in front of the washing container 2 when the link arms 15, 16 are pivoted, i.e. in the extension direction A (arrow) and potentially leading to the domestic dishwasher 1 tipping, a guide device 19 is provided. The guide device 19 comprises a link guide 20 and a link element 21.

Die Kulissenführung 20 ist beispielsweise als Schlitz an oder in der Seitenwand 8 ausgebildet. Die Kulissenführung 20 weist beispielsweise eine in der Auszugsrichtung A (Pfeil) zumindest bereichsweise zunehmende Steigung auf. Hierzu kann die Kulissenführung 20 beispielsweise die Gestalt einer halben Parabel aufweisen, deren Scheitelpunkt S auf einer Längsmittelachse 22 des Lenkerarms 15 liegt, wenn sich dieser in seiner vertikalen Lage befindet, also entsprechend der ersten Position unten und der zweiten Position unten des Geschirrkorbs 10.The link guide 20 is designed, for example, as a slot on or in the side wall 8 . The slotted guide 20 has, for example, an incline that increases at least in regions in the pull-out direction A (arrow). For this purpose, link guide 20 can have the shape of half a parabola, for example, the vertex S of which lies on a longitudinal center axis 22 of link arm 15 when it is in its vertical position, i.e. corresponding to the first position at the bottom and the second position at the bottom of crockery basket 10.

Das Kulissenelement 21 kann beispielsweise als Stift ausgebildet sein, welcher an dem Lenkerarm 15 befestigt ist und von diesem abragt und sich in die Kulissenführung 20 hineinerstreckt. Zusätzlich kann vorgesehen sein, dass der Stift 21 formschlüssig, beispielsweise mittels einer Schwalbenschwanzgeometrie, in der Kulissenführung 20 gehalten ist. Der Formschluss (beispielsweise aufgrund der Schwalbenschwanzgeometrie) besteht somit in einer Breitenrichtung B (Pfeil) der Haushaltsgeschirrspülmaschine 1.The link element 21 can be designed, for example, as a pin which is fastened to the link arm 15 and protrudes from it and extends into the link guide 20 . In addition, it can be provided that the pin 21 is held in the link guide 20 in a form-fitting manner, for example by means of a dovetail geometry. The form fit (for example due to the dovetail geometry) is therefore in a width direction B (arrow) of the domestic dishwasher 1.

Der Lenkerarm 15 weist ferner ein Langloch 23 auf, durch welches sich in der Breitenrichtung B (Pfeil) (siehe die Fig. 4) ein Zapfen 24 erstreckt, welcher an dem Spülbehälter 2 befestigt ist. Der Zapfen 24 bildet dabei zusammen mit dem Langloch 23 den bereits erwähnten Anlenkpunkt 17. Sowie der Geschirrkorb 10 aus seiner zweiten Position unten in seine dritte Position oben verschwenkt, kann der Lenkerarm 15 entsprechend nicht nur um den Zapfen 24 verschwenken, sondern auch eine lineare Relativbewegung bezüglich des Zapfens 24 ausführen. Die lineare Relativbewegung wird durch das Zusammenwirken des Kulissenelements 21 mit der Kulissenführung 20 bewirkt, wobei sich das Langloch 23 gegenüber dem Zapfen 24 verschiebt. Die Kulissenführung 20 definiert somit eine nicht-kreisförmige Führungsbahn für das Kulissenelement 21 und damit für den Geschirrkorb 10.The link arm 15 also has a slot 23 through which in the width direction B (arrow) (see the 4 ) a pin 24 which is attached to the washing container 2 extends. The pin 24 together with the elongated hole 23 forms the already mentioned pivot point 17. As soon as the crockery basket 10 pivots from its second position at the bottom to its third position at the top, the link arm 15 can pivot accordingly not only about the pin 24, but also a linear relative movement run with respect to the pin 24. The linear relative movement is brought about by the interaction of the link element 21 with the link guide 20, with the elongated hole 23 being displaced in relation to the pin 24. The link guide 20 thus defines a non-circular guide path for the link element 21 and thus for the crockery basket 10.

Bei dieser Ausführungsform bildet der Zapfen 24 stets den momentanen Schwenkpunkt bezüglich dessen der Geschirrkorb 10 verschwenkt. Allerdings ändert sich aufgrund der Führungseinrichtung 19 der Abstand zwischen dem Geschirrkorb 10 beziehungsweise einem Schwerpunkt SP desselben und dem Zapfen 24 kontinuierlich, wenn der Geschirrkorb 10 aus seiner zweiten Position unten in seine dritte Position oben (und umgekehrt) verschwenkt. Die Führungseinrichtung 19 modifiziert dabei die eigentliche, in etwa Viertelkreisbewegung der Lenkerarme 15, 16 derart, dass der Geschirrkorb 10 und damit auch dessen Schwerpunkt SP eng an dem Spülbehälter 2 geführt ist und entsprechend ein Verkippen der Haushaltsgeschirrspülmaschine vermieden wird.In this embodiment, the pin 24 always forms the instantaneous pivot point with respect to which the crockery basket 10 pivots. However, due to the guide device 19, the distance between the crockery basket 10 or a center of gravity SP of the same and the pin 24 changes continuously when the crockery basket 10 pivots from its second position below into its third position above (and vice versa). The guide device 19 modifies the actual, approximately quarter-circle movement of the link arms 15, 16 in such a way that the crockery basket 10 and thus also its center of gravity SP is guided closely to the washing compartment 2 and the domestic dishwasher is accordingly prevented from tipping over.

Anhand der Fig. 5, der Fig. 6, der Fig. 7 und der Fig. 8 wird nachfolgend eine zweite Variante einer Mechanik beschrieben, welche es erlaubt, den Geschirrkorb 10 beziehungsweise dessen Schwerpunkt SP nah an dem Spülbehälter 2 nach oben zu führen, wenn dieser aus seiner zweiten Position unten in seine dritte Position oben bewegt wird, so dass ein Verkippen der Haushaltsgeschirrspülmaschine 1 vermieden wird.Based on figure 5 , the 6 , the 7 and the 8 a second variant of a mechanism is described below, which allows the crockery basket 10 or its center of gravity SP to be moved upwards close to the washing compartment 2 when it is moved from its second position at the bottom to its third position at the top, so that the Domestic dishwasher 1 is avoided.

Im Unterschied zur ersten Variante gemäß der Fig. 2, der Fig. 3 und der Fig. 4 umfasst die Mechanik eine Führungseinrichtung 25 mit einem Führungshebel 26. Der Führungshebel 26 ist an seinem einen Ende 26a schwenkbar an dem Spülbehälter 2, insbesondere der Seitenwand 8 schwenkbar angelenkt. Bevorzugt weist das Ende 26a einen Anlenkpunkt 28 an der Seitenwand 8 auf, welcher unter und in der Auszugsrichtung A (Pfeil) vor dem Anlenkpunkt 17 des Lenkerarms 15 (türseitiger Lenkerarm) liegt. An seinem anderen Ende 26b weist der Führungshebel 26 ein in der Fig. 7, der Fig. 8 und der Fig. 9 vergrößert dargestelltes Sperrstück 27 auf. Das Sperrstück 27 ist beispielsweise als ein drehfester Zapfen ausgeführt, welcher sich in der Breitenrichtung B (Pfeil) der Haushaltsgeschirrspülmaschine 1 erstreckt. Ein Querschnitt des Zapfens 27 kann sich in einer in der Fig. 5, der Fig. 6 und der Fig. 7 gezeigten Warteposition des Führungshebels 26 in der Einschieberichtung E (Pfeil) von einer Seite 27a desselben hin zu einer Seite 27b desselben verjüngen. Die Seiten 27a, 27b können gerundet ausgebildet sein. Insbesondere kann der Zapfen 27 einen zu beiden Seiten abgeflachten kreisförmigen Querschnitt aufweisen, wie beispielsweise in der Fig. 7 zu erkennen.In contrast to the first variant according to the 2 , the 3 and the 4 the mechanism includes a guide device 25 with a guide lever 26. The guide lever 26 is pivoted at one end 26a on the washing compartment 2, in particular the side wall 8, in a pivotable manner. Preferably, the end 26a an articulation point 28 on the side wall 8, which is below and in the extension direction A (arrow) in front of the articulation point 17 of the link arm 15 (door-side link arm). At its other end 26b, the guide lever 26 in the 7 , the 8 and the 9 Locking piece 27 shown enlarged. The locking piece 27 is designed, for example, as a non-rotatable pin, which extends in the width direction B (arrow) of the domestic dishwasher 1 . A cross section of the pin 27 can be in a in the figure 5 , the 6 and the 7 shown waiting position of the guide lever 26 in the insertion direction E (arrow) of the same taper from one side 27a to a side 27b thereof. The sides 27a, 27b can be rounded. In particular, the pin 27 can have a circular cross-section flattened on both sides, as for example in FIG 7 to recognize.

An dem Geschirrkorb 10 ist ein zu dem Sperrstück beziehungsweise zapfenförmiges Element 27 korrespondierendes Sperrgegenstück 30 drehfest befestigt, welches in der Fig. 7, der Fig. 8 und der Fig. 9 vergrößert dargestellt ist. Das Sperrgegenstück 30 ist beispielsweise als C-förmiges Element mit einer radialen Öffnung 31 ausgeführt. Mittels der radialen Öffnung 31 kann das C-förmige Element 30 über das zapfenförmige Element 27 bewegt werden, wenn der Geschirrkorb 10 aus seiner nicht gezeigten ersten Position unten in seine in der Fig. 5 gezeigte zweite Position unten linear verschoben wird. Der verjüngte Querschnitt des zapfenförmigen Elements 27 dient dabei als Einführhilfe. "Radial" bezieht sich hier auf die Längsachse des zapfenförmigen Elements 27 beziehungsweise des C-förmigen Elements 30, welches sich in der Breitenrichtung B (Pfeil) erstreckt.On the crockery basket 10 to the locking piece or pin-shaped element 27 corresponding locking counterpart 30 is rotatably attached, which in the 7 , the 8 and the 9 is shown enlarged. The locking counterpart 30 is designed, for example, as a C-shaped element with a radial opening 31 . By means of the radial opening 31, the C-shaped element 30 can be moved over the pin-shaped element 27 when the crockery basket 10 from its first position, not shown, down into its in the figure 5 second position shown is linearly shifted down. The tapered cross section of the pin-shaped element 27 serves as an insertion aid. "Radial" here refers to the longitudinal axis of the peg-shaped element 27 or the C-shaped element 30, which extends in the width direction B (arrow).

In seiner Warteposition liegt der Führungshebel 26 gegen einen Anschlag, beispielsweise in Form eines Zapfens 32 an der Seitenwand 8 an. Der Führungshebel 26 befindet sich sowohl in der ersten Position unten als auch in der zweiten Position unten des Geschirrkorbs 10 in der Warteposition.In its waiting position, the guide lever 26 rests against a stop, for example in the form of a pin 32 on the side wall 8 . The guide lever 26 is in the waiting position both in the first position below and in the second position below the dish rack 10 .

Auch das zapfenförmige Element 27 und das C-förmige Element 30 befinden sich in der ersten Position unten und in der zweiten Position unten des Geschirrkorbs 10 in einem Freigabezustand, das heißt, ein lineares Verlagern dieser relativ zueinander in der Auszugsrichtung A (Pfeil) oder der Einschieberichtung E (Pfeil) ist möglich.The pin-shaped element 27 and the C-shaped element 30 are also in the first position at the bottom and in the second position at the bottom of the crockery basket 10 in a released state, i.e. a linear displacement of these relative to one another in the extension direction A (arrow) or der Insertion direction E (arrow) is possible.

Da das zapfenförmige Element 27 drehfest mit dem Führungshebel 26 und das C-förmige Element 30 drehfest mit dem Geschirrkorb 10 verbunden sind, führt ein Verschwenken des Geschirrkorbs 10 aus dessen zweiter Position unten in dessen dritte Position oben zu einem Drehen des zapfenförmigen Elements 27 um eine Drehachse D (ist zugleich die oben erwähnte Längsachse) in dem C-förmigen Element 30. Dies wiederum bewirkt, dass das C-förmige Element 30 das zapfenförmige Element 27 an dessen Seite 27a zunehmend hintergreift. Die Fig. 8 korrespondiert dabei zu einer Zwischenposition des Geschirrkorbs 10 zwischen seiner zweiten, in der Fig. 7 gezeigten Position unten und seiner dritten, in der Fig. 9 gezeigten Position oben. Mithin stellt sich in der Zwischenposition sowie der dritten Position oben des Geschirrkorbs 1 ein Sperrzustand ein, in welchem ein lineares Verlagern des Geschirrkorbs 10 in der Auszugsrichtung A (Pfeil) sowie in der Einschieberichtung E (Pfeil) gesperrt ist, was einem Sperrzustand des zapfenförmigen Elements 27 und des C-förmigen Elements 30 entspricht. Gleichzeitig ergibt sich damit, dass der Geschirrkorb 10 zwangsweise auf einer Kreisbahn verschwenkt wird, deren Mittelpunkt dem Anlenkpunkt 28 des Führungshebels 26 an dem Spülbehälter 2 entspricht. Die Lenkerarme 15, 16 sind gemäß der zweiten Variante ausschließlich drehbar, also nicht wie bei der ersten Variante (Fig. 2, Fig. 4 und Fig. 4) verschiebbar bezüglich ihrer jeweiligen Anlenkpunkte 17 an dem Spülbehälter 2 vorgesehen. Entsprechend verschiebt sich der Geschirrkorb 10 relativ zu der Führungsschiene 12, um der durch den Führungshebel 26 vorgegebenen Kreisbahn folgen zu können. Insbesondere wird der Geschirrkorb 10 bei seiner Bewegung aus der zweiten Position unten in die dritte Position oben entlang der Führungsschiene 12 zurückgeschoben (also in der Einschieberichtung E (Pfeil) bewegt). Entsprechend kann der Geschirrkorb 10 bzw. dessen Schwerpunkt SP auch bei der zweiten Variante eng an dem Spülbehälter 2 nach oben bewegt werden, wodurch ein Verkippen der Haushaltsgeschirrspülmaschine 1 vermieden wird. Dadurch, dass eine Schwenkachse SW (siehe die Fig. 7), um welche der Geschirrkorb 10 relativ zu dem Führungshebel 26 verschwenkt, achsgleich mit der Drehachse D ist, können der Sperrzustand und der Freigabezustand auf mechanisch einfache Weise bereitgestellt werden.Since the pin-shaped element 27 is non-rotatably connected to the guide lever 26 and the C-shaped element 30 is non-rotatably connected to the crockery basket 10, pivoting the crockery basket 10 from its second position at the bottom to its third position at the top causes the pin-shaped element 27 to rotate by one Axis of rotation D (which is also the longitudinal axis mentioned above) in the C-shaped element 30. This in turn causes the C-shaped element 30 to increasingly engage behind the pin-shaped element 27 on its side 27a. The 8 corresponds to an intermediate position of the dish rack 10 between its second, in which 7 shown position below and its third, in the 9 position shown above. Consequently, in the intermediate position and in the third position at the top of the crockery basket 1, a blocked state occurs in which a linear displacement of the crockery basket 10 in the extension direction A (arrow) and in the insertion direction E (arrow) is blocked, which means a blocked state of the pin-shaped element 27 and the C-shaped element 30 corresponds. At the same time, this results in the crockery basket 10 being forced to pivot on a circular path, the center point of which corresponds to the articulation point 28 of the guide lever 26 on the washing container 2 . According to the second variant, the link arms 15, 16 can only be rotated, ie not as in the first variant ( 2 , Figures 4 and 4 ) displaceably provided with respect to their respective pivot points 17 on the washing compartment 2. Correspondingly, the crockery basket 10 moves relative to the guide rail 12 in order to be able to follow the circular path specified by the guide lever 26 . In particular, the crockery basket 10 is pushed back along the guide rail 12 during its movement from the second position at the bottom to the third position at the top (ie moved in the direction of insertion E (arrow)). Correspondingly, the crockery basket 10 or its center of gravity SP can also be moved upwards close to the washing compartment 2 in the second variant, thereby preventing the domestic dishwasher 1 from tipping over. Because a swivel axis SW (see the 7 ) about which the crockery basket 10 pivots relative to the guide lever 26 is coaxial with the axis of rotation D, the locked state and the released state can be provided in a mechanically simple manner.

Anhand der Fig. 10 und der Fig. 11 wird nachfolgend eine dritte Variante einer Mechanik erläutert, welche ein Kippen der Haushaltsgeschirrspülmaschine 1 sicher vermeiden soll.Based on 10 and the 11 a third variant of a mechanism is explained below, which is intended to reliably prevent the domestic dishwasher 1 from tipping over.

Im Unterschied zu der zweiten Variante gemäß der Fig. 5, der Fig. 6, Fig. 7, der Fig. 8 und der Fig. 9 geschieht die Zwangsführung des Geschirrkorbs 10 bei der dritten Variante mittels einer Führungseinrichtung 33, welche eine Führungsschiene 34 umfasst. Die Führungsschiene 34 erstreckt sich in vertikaler Richtung. Die Führungsschiene 34 kann zwei Seitenwände 34a, 34b umfassen. Die Seitenwände 34a, 34b können sich in der Auszugsrichtung A (Pfeil) gegenüberliegen. Die in der Auszugsrichtung A (Pfeil) vor der Seitenwand 34a liegende Seitenwand 34b kann an einem unteren Abschnitt 36 der Führungsschiene 34 verkürzt ausgebildet sein. Damit ist ein Weg für ein an dem Geschirrkorb 10 angebrachtes Führungselement 37 der Führungseinrichtung 33 freigegeben, so dass dieses beim linearen Verlagern des Geschirrkorbs 10 aus seiner nicht gezeigten, ersten Position unten in seine in der Fig. 10 gezeigte zweite Position unten in Anlage mit der Seitenwand 34a gelangt. Ein weiteres Herausziehen des Geschirrkorbs 10 in der Richtung A ist damit gesperrt. Der Geschirrkorb 10 kann nunmehr in vertikaler Richtung entlang der Führungsschiene 34 aus seiner zweiten Position unten (siehe die Fig. 10) in seine dritte Position oben (siehe die Fig. 11) bewegt werden. Dabei gelangt das Führungselement 37, welches beispielsweise als Laufrolle ausgeführt sein kann, über eine vertikale Öffnung 38 zwischen die beiden Seitenwände 34a, 34b, so dass nach Verlassen der zweiten Position unten ein lineares Verlagern des Geschirrkorbs 10 in der Auszugsrichtung A (Pfeil) und in der Einschieberichtung E (Pfeil) gesperrt ist.In contrast to the second variant according to the figure 5 , the 6 , 7 , the 8 and the 9 in the third variant, the restricted guidance of the crockery basket 10 takes place by means of a guide device 33 which comprises a guide rail 34 . The guide rail 34 extends in the vertical direction. The guide rail 34 can include two side walls 34a, 34b. The side walls 34a, 34b can be opposite one another in the pull-out direction A (arrow). The side wall 34b lying in front of the side wall 34a in the pull-out direction A (arrow) can be shortened on a lower section 36 of the guide rail 34 . This opens up a path for a guide element 37 of the guide device 33 attached to the crockery basket 10, so that when the crockery basket 10 is linearly displaced from its first position, which is not shown, it moves down into its in the 10 second position shown below comes into contact with the side wall 34a. A further pulling out of the crockery basket 10 in direction A is thus blocked. The crockery basket 10 can now be moved in a vertical direction along the guide rail 34 from its second position below (see Figs 10 ) to its third position above (see the 11 ) can be moved. The guide element 37, which can be designed as a roller, for example, reaches between the two side walls 34a, 34b via a vertical opening 38, so that after leaving the second position at the bottom, a linear displacement of the crockery basket 10 in the pull-out direction A (arrow) and in the insertion direction E (arrow) is blocked.

Wie schon bei der zweiten Variante ergeben die Lenkerarme 15, 16 auch bei der dritten Variante eine Bewegung der Führungsschiene 12 auf einer Kreisbahn vor. Um dennoch die lineare Bewegung des Geschirrkorbs 10 in vertikaler Richtung zu erlauben, bewegt sich der Geschirrkorb 10 relativ zu der Führungsschiene 12. Insbesondere wird der Geschirrkorb 10 entlang der Führungsschiene 12 zurückgeschoben, wenn er aus seiner zweiten Position unten in seine dritte Position oben gelangt.As in the second variant, the link arms 15, 16 also result in a movement of the guide rail 12 on a circular path in the third variant. In order to still allow the linear movement of the dish rack 10 in the vertical direction, the dish rack 10 moves relative to the guide rail 12. In particular, the dish rack 10 is pushed back along the guide rail 12 when it comes from its second position down to its third position up.

Entsprechend kann auch bei der dritten Variante der Geschirrkorb 10 beziehungsweise dessen Schwerpunkt SP eng an dem Spülbehälter 2 nach oben geführt werden, so dass ein Kippen der Haushaltsgeschirrspülmaschine 1 sicher vermieden werden kann.Correspondingly, in the third variant too, the crockery basket 10 or its center of gravity SP can be guided upwards close to the washing compartment 2, so that the household dishwasher 1 can be reliably prevented from tipping over.

Obgleich nur für die erste und zweite Variante (siehe die Fig. 3 beziehungsweise die Fig. 6) gezeigt, kann auch bei der dritten Variante ein Vollauszug dargestellt werden, das heißt, dass sich der Geschirrkorb 10 in seiner zweiten Position unten vollständig außerhalb der Spülkammer 4 befindet. Hierzu kann das Führungselement 37 mit einem entsprechenden Abstandshalter an dem Geschirrkorb 10 gehalten werden.Although only for the first and second variant (see the 3 or the 6 ) shown, a full extension can also be shown in the third variant, which means that the crockery basket 10 can be completely lowered in its second position outside the washing chamber 4 is located. For this purpose, the guide element 37 can be held on the crockery basket 10 with a corresponding spacer.

Ganz allgemein kann das Bewegen des Geschirrkorbs 10 zwischen seinen drei Positionen manuell oder teilweise oder vollständig automatisiert erfolgen. Beispielsweise kann en Elektromotor vorgesehen sein, welcher die Lenkerarme 15, 16 um ihre jeweiligen Anlenkpunkte 17 verschwenkt. Alternativ oder zusätzlich kann auch eine Feder vorgesehen sein, welche diese Aufgabe in zumindest einer Schwenkrichtung übernimmt. Selbstverständlich kann zwecks einer symmetrischen Abstützung des Geschirrkorbs 10 die für die erste bis dritte Variante erläuterte Mechanik zusätzlich an der der Seitenwand 8 gegenüberliegenden Seitenwand 9 vorgesehen sein.In general, moving the dish rack 10 between its three positions can be manual or partially or fully automated. For example, an electric motor can be provided, which pivots the link arms 15, 16 about their respective pivot points 17. Alternatively or additionally, a spring can also be provided, which takes on this task in at least one pivoting direction. Of course, the mechanism explained for the first to third variants can also be provided on the side wall 9 opposite the side wall 8 for the purpose of symmetrical support of the crockery basket 10 .
