Description

Die vorliegende Erfindung betrifft eine Haushalts-Geschirrspülmaschine.The present invention relates to a domestic dishwasher.

Eine Haushalts-Geschirrspülmaschine umfasst einen Spülbehälter und eine verschwenkbar an dem Spülbehälter gelagerte Tür zum Verschließen desselben. Die Tür kann mit Hilfe einer Feder in Richtung ihres geschlossenen Zustands federvorgespannt sein, so dass diese bei einem Entriegeln derselben sich nicht unkontrolliert öffnet und einen Benutzer verletzt. Zur Überwachung eines Fehlerfalls dieser Feder können beispielsweise Mikroschalter eingesetzt werden. Ein derartiges Überwachungssystem kann beispielsweise verhindern, dass ein Trocknungsassistent im Fehlerfall die Tür automatisch öffnet und die Tür mit voller Wucht herunterfällt.A household dishwasher comprises a washing container and a door which is pivotably mounted on the washing container and is intended to close the same. The door can be spring-pretensioned in the direction of its closed state with the aid of a spring, so that it does not open in an uncontrolled manner and injure a user when it is unlocked. Microswitches, for example, can be used to monitor a fault in this spring. Such a monitoring system can, for example, prevent a drying assistant from automatically opening the door in the event of a fault and the door from falling down with full force.

Die EP 2 636 355 B1 beschreibt eine Geschirrspülmaschine mit einer um eine horizontal verlaufende Achse schwenkbaren Tür zum Verschluss eines Behandlungsraums, welche mit einer Türfeder versehen ist, die dazu dient, die Bewegung der Tür beim Herunterschwenken abzubremsen, und mit einem Sensor, mit dem die Funktionsfähigkeit der Türfeder überwacht werden kann, und einem zusätzlichen Entschleunigungsmittel, welches im Falle eines durch den Sensor erkannten Versagens der Türfeder aktiviert wird und geeignet ist, die Bewegung der Tür beim Herunterschwenken abzubremsen.The EP 2 636 355 B1 describes a dishwasher with a door that can be pivoted about a horizontal axis to close a treatment room, which door is provided with a door spring which is used to brake the movement of the door when it is pivoted down, and with a sensor with which the functionality of the door spring can be monitored , and an additional deceleration device, which is activated in the event of a failure of the door spring detected by the sensor and is suitable for decelerating the movement of the door when it is pivoted down.

Die DE 11 2007 000 423 B4 zeigt eine Geschirrspülmaschine, die ein Gehäuse, das zur Aufnahme von Geschirr, das darin gespült werden soll, eine Öffnung in einer Vorderseite und eine Gelenkwelle aufweist, eine Tür, die zum selektiven Öffnen/Schließen der Öffnung im Gehäuse drehbar mit der Gelenkwelle angebracht ist, und eine Abfallverhinderungseinheit aufweist, um zu verhindern, dass die Tür in einem Fall, dass sich die Tür dreht, von der Gelenkwelle abfällt, wobei die Abfallverhinderungseinheit einen Gelenkhalter aufweist, der an der Tür vorgesehen ist, wobei der Gelenkhalter einen darin ausgebildeten Gelenkschlitz aufweist, um die Gelenkwelle darin anzuordnen, wobei der Gelenkschlitz eine Einsatzöffnung zum Einsetzen der Gelenkwelle dort hindurch, einen Sitzabschnitt zum Setzen der Gelenkwelle wenn die Tür geschlossen ist, und eine Haltestufe, die in einem vorgegebenen Abstand von dem Sitzabschnitt angeordnet ist, aufweist, wobei die Haltestufe dazu geeignet ist die Gelenkwelle zu halten, wenn sich die Gelenkwelle eine vorgegebene Strecke bewegt, um die Tür zu öffnen, und wobei ein Innenumfang des Gelenkschlitzes, der die Einsatzöffnung mit dem Sitzabschnitt verbindet, mindestens einmal gebogen ist.The DE 11 2007 000 423 B4 Fig. 12 shows a dishwasher having a housing having an opening in a front side and a hinge shaft for receiving dishes to be washed therein, a door rotatably mounted with the hinge shaft for selectively opening / closing the opening in the housing, and a waste prevention unit for preventing the door from falling off the hinge shaft in a case that the door rotates, the waste prevention unit including a hinge holder provided on the door, the hinge holder having a hinge slot formed therein, to arrange the hinge shaft therein, the hinge slot having an insertion opening for inserting the hinge shaft therethrough, a seat portion for setting the hinge shaft when the door is closed, and a holding step located a predetermined distance from the seat portion, the holding step the PTO shaft is suitable for holding it when the The hinge shaft is moved a predetermined distance to open the door, and wherein an inner periphery of the hinge slot connecting the insert opening with the seat portion is bent at least once.

Die EP 0 692 598 A1 sieht für die Tür eines elektrischen Haushaltsgeräts ein Türgewichtsausgleichssystem vor, bei dem eine Spiralfeder auf einem ausziehbaren Element so befestigt ist, dass auf sie eine zunehmende Kompressionskraft beim Türöffnen ausgeübt wird und sie auch in der Schließendstellung der Tür unter Kompressionsspannung bleibt. Das ausziehbare Element weist zwei sich abschnittsweise überlappende und gegensätzlich zueinander angeordnete "T"- artige Flachstäbe auf, zwischen deren breiteren Kopfenden die Kompressionsfeder gehalten ist. An das schmalere Ende des einen "T"-artigen Flachstabs ist das eine Ende eines Kabels befestigt. Dessen anderes Ende ist an der feststehenden Rahmenstruktur des Haushaltsgeräts befestigt. Das freie, schmalere Ende des anderen "T"- förmigen Flachstabs ist über einen Verbindungshebel mit einem mehrteiligen Scharnierhebel der Tür verbunden. Auch wenn die Kompressionsfeder bricht, steht diese unter einer solchen Kompressionskraft, dass ein freies Herunterfallen der Tür verhindert ist.The EP 0 692 598 A1 provides a door weight compensation system for the door of an electrical household appliance in which a spiral spring is attached to an extendable element in such a way that an increasing compression force is exerted on it when the door is opened and it remains under compression tension even in the closed end position of the door. The pull-out element has two "T" -like flat bars which overlap in sections and are arranged in opposition to one another, between the wider head ends of which the compression spring is held. One end of a cable is attached to the narrower end of a "T" -like flat rod. Its other end is attached to the fixed frame structure of the household appliance. The free, narrower end of the other "T" -shaped flat bar is connected to a multi-part hinge lever of the door via a connecting lever. Even if the compression spring breaks, it is under such a compression force that the door is prevented from falling freely.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, eine verbesserte Haushalts-Geschirrspülmaschine vorzuschlagen.Against this background, an object of the present invention is to propose an improved household dishwasher.

Demgemäß wird eine Haushalts-Geschirrspülmaschine mit einem Spülbehälter, einer Tür zum Verschließen des Spülbehälters, einem Scharnier, mit dessen Hilfe die Tür verschwenkbar an dem Spülbehälter angeschlagen ist, um die Tür von einem geöffneten Zustand in einen geschlossenen Zustand und umgekehrt zu verbringen, einer Vorspanneinrichtung, die die Tür in Richtung des geschlossenen Zustands federvorspannt, und einer rein mechanisch arbeitenden Arretiereinrichtung vorgeschlagen. Die Arretiereinrichtung ist dazu eingerichtet, die Tür bei einer Beschädigung der Vorspanneinrichtung zu arretieren, um ein selbsttätiges Verbringen der Tür in den geöffneten Zustand zu verhindern.Accordingly, a household dishwasher with a washing container, a door for closing the washing container, a hinge with the help of which the door is hinged to the washing container so as to move the door from an open state to a closed state and vice versa, a pretensioning device , which biases the door in the direction of the closed state, and proposed a purely mechanical locking device. The locking device is designed to lock the door in the event of damage to the pretensioning device in order to prevent the door from being automatically brought into the open state.

Dadurch, dass die Arretiereinrichtung vorgesehen ist, kann zuverlässig verhindert werden, dass sich die Tür bei einem Entriegeln derselben unkontrolliert öffnet. Eine Verletzung eines Benutzers wird hierdurch vermieden. Auf kostenintensive und fehleranfällig elektronische Bauteile kann verzichtet werden. Hierdurch kann die Haushalts-Geschirrspülmaschine kostengünstig hergestellt werden.The fact that the locking device is provided can reliably prevent the door from opening in an uncontrolled manner when it is unlocked. This avoids injury to a user. On cost-intensive and error-prone electronic components can be dispensed with. This allows the household dishwasher to be manufactured inexpensively.

Die Vorspanneinrichtung dient insbesondere dazu, eine Bewegung der Tür beim öffnen derselben abzubremsen. Die Vorspanneinrichtung kann daher auch als Bremseinrichtung bezeichnet werden. Unter einer Beschädigung der Vorspanneinrichtung ist zu verstehen, dass diese reißt oder bricht. Beispielsweise kann die Vorspanneinrichtung ein Seil und/oder ein Federelement aufweisen. Bei einem Brechen oder Reißen des Seils und/oder des Federelements arretiert die Arretiereinrichtung die Tür. In dem geöffneten Zustand verschließt die Tür den Spülbehälter, und in dem geschlossenen Zustand ist eine Beschickungsöffnung des Spülbehälters offen, so dass in dem geöffneten Zustand eine Spülgutaufnahme der Haushalts-Geschirrspülmaschine aus dem Spülbehälter heraus- und in diesen hineinverlagert werden kann. In dem Spülbehälter sind vorzugsweise mehrere, beispielsweise drei, Spülgutaufnahmen übereinander angeordnet. In den Spülgutaufnahmen kann Spülgut aufgenommen werden.The pretensioning device serves in particular to decelerate a movement of the door when it is opened. The pretensioning device can therefore also be referred to as a braking device. Damage to the pretensioning device is understood to mean that it tears or breaks. For example, the pretensioning device can have a rope and / or a spring element. If the cable and / or the spring element break or tear, the locking device locks the door. In the open state, the door closes the washing container, and in the closed state a loading opening of the washing container is open, so that in the open state a washware receptacle of the domestic dishwasher can be moved out of and into the washing container. Several, for example three, washware receptacles are preferably arranged one above the other in the washing container. Wash ware can be accommodated in the wash ware receptacles.

Bei dem Verbringen der Tür von dem geschlossenen Zustand in den geöffneten Zustand wird die Vorspanneinrichtung vorgespannt. In dem geschlossenen Zustand ist die Vorspanneinrichtung vorzugsweise zumindest annähernd entspannt. Die Vorspanneinrichtung ist insbesondere dazu eingerichtet, gegen ein Eigengewicht der Tür zu wirken. Die Vorspanneinrichtung ist jedoch vorzugsweise nicht so stark ausgelegt, dass diese die Tür selbstständig schließen kann. Die Vorspanneinrichtung unterstützt nur ein Schließen der Tür beziehungsweise bremst diese bei einem Öffnen derselben ab. Unter einem selbsttätigen Verbringen der Tür in den geöffneten Zustand ist vorliegend beispielsweise zu verstehen, dass sich die Tür aufgrund ihres Eigengewichts ohne eine externe Krafteinbringung öffnet. Insbesondere dann, wenn die Tür entriegelt ist.When the door is brought from the closed state into the open state, the pretensioning device is pretensioned. In the closed state, the pretensioning device is preferably at least approximately relaxed. The pretensioning device is designed in particular to act against the door's own weight. However, the pretensioning device is preferably not designed so strong that it can close the door independently. The pretensioning device only supports closing the door or brakes it when it is opened. In the present case, automatic movement of the door into the open state is to be understood as meaning, for example, that the door opens due to its own weight without an external force being applied. Especially when the door is unlocked.

Darunter, dass die Arretiereinrichtung rein mechanisch arbeitet oder wirkt, ist zu verstehen, dass die Arretiereinrichtung keinerlei elektronische Komponenten, wie beispielsweise Sensoren, Schalter, Aktoren oder dergleichen umfasst. Das heißt, die Arretiereinrichtung ist sensorlos oder sensorfrei. Die Arretiereinrichtung umfasst genauer gesagt nur mechanische Bauteile, die miteinander, beispielsweise zur Kraftübertragung, in Wechselwirkung stehen. Die Arretiereinrichtung kann eine Bremse sein. Insbesondere ist die Arretiereinrichtung dazu eingerichtet, die Tür mechanisch zu blockieren oder zumindest abzubremsen.The fact that the locking device works or acts purely mechanically is to be understood as meaning that the locking device does not include any electronic components such as sensors, switches, actuators or the like. That is, the locking device is sensorless or sensorless. More precisely, the locking device comprises only mechanical components that interact with one another, for example for power transmission. The locking device can be a brake. In particular the locking device is set up to mechanically block the door or at least to brake it.

Vorzugsweise umfasst die Haushalts-Geschirrspülmaschine zwei derartige Scharniere, die an einander gegenüberliegenden Seitenwänden des Spülbehälters vorgesehen sind. Die Scharniere können an einem Basisträger und/oder an einem Rahmen des Spülbehälters vorgesehen sein. Mit Hilfe der Scharniere ist die Tür um eine Drehachse verschwenkbar, um diese von dem geöffneten Zustand in den geschlossenen Zustand und umgekehrt zu verbringen. Nachfolgend wird jedoch auf nur ein Scharnier eingegangen.The household dishwasher preferably comprises two such hinges which are provided on opposite side walls of the washing container. The hinges can be provided on a base support and / or on a frame of the washing compartment. With the aid of the hinges, the door can be pivoted about an axis of rotation in order to move it from the open state to the closed state and vice versa. However, only one hinge is discussed below.

Erfindungsgemäß umfasst die Arretiereinrichtung ein Eingriffselement, das mit dem Scharnier gekoppelt ist, und ein Gegeneingriffselement, wobei das Eingriffselement zum Arretieren der Tür formschlüssig in das Gegeneingriffselement eingreift.According to the invention, the locking device comprises an engagement element, which is coupled to the hinge, and a counter-engagement element, the engagement element engaging with the counter-engagement element in a form-fitting manner for locking the door.

Insbesondere ist das Eingriffselement drehbar mit dem Scharnier gekoppelt. Eine formschlüssige Verbindung entsteht durch das Ineinander- oder Hintergreifen von mindestens zwei Verbindungspartnern, in diesem Fall dem Eingriffselement und dem Gegeneingriffselement. Das Eingriffselement umfasst insbesondere einen stabförmigen Bolzenabschnitt, der drehbar in einen Scharnierhebel des Scharniers eingehängt ist. Das heißt, das Eingriffselement ist vorzugsweise um den Bolzenabschnitt relativ zu dem Scharnierhebel drehbar.In particular, the engagement element is rotatably coupled to the hinge. A positive connection is created by the interlocking or interlocking of at least two connection partners, in this case the engagement element and the counter-engagement element. The engagement element comprises in particular a rod-shaped bolt section which is rotatably suspended in a hinge lever of the hinge. That is, the engagement element is preferably rotatable about the bolt section relative to the hinge lever.

Gemäß einer weiteren Ausführungsform umfasst das Eingriffselement eine Vielzahl Eingriffshaken, und das Gegeneingriffselement umfasst eine Vielzahl zu den Eingriffshaken korrespondierende Gegeneingriffshaken.According to a further embodiment, the engagement element comprises a plurality of engagement hooks, and the counter-engagement element comprises a plurality of counter-engagement hooks corresponding to the engagement hooks.

Insbesondere sind erste und zweite Eingriffshaken vorgesehen. Die Eingriffshaken sind insbesondere dazu eingerichtet, formschlüssig in die Gegeneingriffshaken einzugreifen, um das Eingriffselement formschlüssig mit dem Gegeneingriffselement zu verbinden.In particular, first and second engagement hooks are provided. The engagement hooks are designed in particular to engage the counter-engagement hooks in a form-fitting manner in order to connect the engagement element to the counter-engagement element in a form-fitting manner.

Gemäß einer weiteren Ausführungsform umfasst die Arretiereinrichtung ein Federelement, das das Eingriffselement in Richtung des Gegeneingriffselements federvorspannt.According to a further embodiment, the locking device comprises a spring element which spring-biases the engagement element in the direction of the counter-engagement element.

Das Federelement ist insbesondere eine Zylinderfeder. Vorzugsweise kann das Federelement eine Zugfeder sein. Das Federelement weist insbesondere einen an dem Scharnierhebel vorgesehenen ersten Befestigungspunkt und einen an dem Eingriffselement vorgesehenen zweiten Befestigungspunkt auf. Mit Hilfe des Federelements ist, je nach Anordnung des Federelements, bei einer Beschädigung der Vorspanneinrichtung eine Drehbewegung des Eingriffselements um den Bolzenabschnitt im Uhrzeigersinn oder entgegen dem Uhrzeigersinn möglich. Bei einer Beschädigung der Vorspanneinrichtung verlagert das Federelement das Eingriffselement dann so in Richtung des Gegeneingriffselements, dass das Eingriffselement formschlüssig in das Gegeneingriffselement eingreift und die Tür blockiert.The spring element is in particular a cylinder spring. The spring element can preferably be a tension spring. The spring element in particular has a first fastening point provided on the hinge lever and a second fastening point provided on the engagement element. With the aid of the spring element, depending on the arrangement of the spring element, if the pretensioning device is damaged, a clockwise or counterclockwise rotation of the engagement element around the bolt section is possible. If the pretensioning device is damaged, the spring element then displaces the engagement element in the direction of the counter-engagement element in such a way that the engagement element engages positively in the counter-engagement element and blocks the door.

Gemäß einer weiteren Ausführungsform ist das Eingriffselement tannenbaumförmig.According to a further embodiment, the engagement element is shaped like a fir tree.

Unter einer tannenbaumförmigen Geometrie ist vorliegend zu verstehen, dass das Eingriffselement keilförmig ist und eine Vielzahl beidseits angeordneter Eingriffshaken aufweist. Dabei verjüngt sich das Eingriffselement ausgehend von einem Endabschnitt des Eingriffselements, an dem die Vorspanneinrichtung befestigt ist, in Richtung des Bolzenabschnitts. Insbesondere ist die Vorspanneinrichtung mit Hilfe des Eingriffselements mit dem Scharnier und insbesondere dem Scharnierhebel des Scharniers gekoppelt.In the present case, a fir tree-shaped geometry is to be understood as meaning that the engagement element is wedge-shaped and has a large number of engagement hooks arranged on both sides. In this case, the engagement element tapers, starting from an end section of the engagement element to which the pretensioning device is attached, in the direction of the bolt section. In particular, the pretensioning device is coupled to the hinge and in particular to the hinge lever of the hinge with the aid of the engagement element.

Gemäß einer weiteren Ausführungsform ist das Eingriffselement ein Kunststoffbauteil und/oder ein Metallbauteil.According to a further embodiment, the engagement element is a plastic component and / or a metal component.

Das Eingriffselement kann beispielsweise ein Kunststoffspritzgussbauteil sein. Hierdurch kann das Eingriffselement kostengünstig in großen Stückzahlen hergestellt werden. Das Eingriffselement kann einen Aufnahmeabschnitt aufweisen, der korrespondierend zu einem zylinderförmigen Endabschnitt des Seils der Vorspanneinrichtung ausgebildet ist. Hierdurch kann der Endabschnitt formschlüssig in dem Aufnahmeabschnitt aufgenommen werden. Beispielsweise kann der Endabschnitt in den Aufnahmeabschnitt eingeclipst oder eingeschnappt werden. Hierdurch ist eine einfache und schnelle Verbindung der Vorspanneinrichtung mit dem Eingriffselement möglich. Das Eingriffselement kann auch ein Metallbauteil, beispielsweise ein Aluminiumdruckgussbauteil, sein. Das Eingriffselement kann auch ein Verbundbauteil sein. Das heißt, das Eingriffselement kann sowohl aus einem Kunststoffmaterial als auch aus einem Metallwerkstoff gefertigt sein. Beispielsweise kann das Eingriffselement einen von einem Kunststoffmaterial umspritzten Kern aufweisen. Der Kern kann symmetrisch oder unsymmetrisch aufgebaut sein. Für den Fall, dass der Kern unsymmetrisch aufgebaut ist, kann auf die Federeinrichtung zum Vorspannen das Eingriffselement in Richtung des Gegeneingriffselements verzichtet werden. Das Eingriffselement wird hierbei durch seine eigene Gewichtskraft in Richtung des Gegeneingriffselements verlagert, sobald die Vorspanneinrichtung beschädigt ist.The engagement element can for example be a plastic injection-molded component. As a result, the engagement element can be manufactured in large numbers at low cost. The engagement element can have a receiving section which is designed to correspond to a cylindrical end section of the cable of the pretensioning device. As a result, the end section can be received in the receiving section in a form-fitting manner. For example, the end section can be clipped or snapped into the receiving section. This enables the pretensioning device to be connected to the engagement element quickly and easily. The engagement element can also be a metal component, for example a die-cast aluminum component. The Engagement element can also be a composite component. That is to say, the engagement element can be made both from a plastic material and from a metal material. For example, the engagement element can have a core overmolded by a plastic material. The core can be constructed symmetrically or asymmetrically. In the event that the core is constructed asymmetrically, the spring device for pretensioning the engagement element in the direction of the counter-engagement element can be dispensed with. The engagement element is displaced by its own weight in the direction of the counter-engagement element as soon as the pretensioning device is damaged.

Gemäß einer weiteren Ausführungsform umfasst das Scharnier einen Scharnierhebel, in den das Eingriffselement eingehängt ist.According to a further embodiment, the hinge comprises a hinge lever into which the engagement element is suspended.

Der Scharnierhebel ist insbesondere aus einem Stahlwerkstoff gefertigt. Der Scharnierhebel ist insbesondere ein Blechbauteil. Der Scharnierhebel umfasst einen nutförmigen Aufnahmeabschnitt, in den der Bolzenabschnitt des Eingriffselements insbesondere drehbar eingehängt ist.The hinge lever is made in particular from a steel material. The hinge lever is in particular a sheet metal component. The hinge lever comprises a groove-shaped receiving section in which the bolt section of the engagement element is suspended, in particular rotatably.

Gemäß einer weiteren Ausführungsform ist das Gegeneingriffselement feststehend an der Haushalts-Geschirrspülmaschine angebracht.According to a further embodiment, the counter-engagement element is fixedly attached to the household dishwasher.

Beispielsweise kann das Gegeneingriffselement an dem Spülbehälter oder an dem Basisträger der Haushalts-Geschirrspülmaschine angebracht sein. Darunter, dass das Gegeneingriffselement feststehend ist, ist zu verstehen, dass dieses nicht drehbar und nicht relativ zu dem Spülbehälter verlagerbar ist.For example, the counter-engagement element can be attached to the washing compartment or to the base support of the domestic dishwasher. The fact that the counter-engagement element is stationary is to be understood as meaning that it cannot be rotated and cannot be displaced relative to the washing container.

Gemäß einer Ausführungsform ist das Gegeneingriffselement kreisbogenförmig.According to one embodiment, the counter-engagement element is circular arc-shaped.

Es können mehr als ein Gegeneingriffselement vorgesehen sein. Beispielsweise können ein erstes Gegeneingriffselement und ein zweites Gegeneingriffselement vorgesehen sein. Das Gegeneingriffselement weist jeweils, wie zuvor erwähnt, eine Vielzahl Gegeneingriffshaken auf, so dass das Gegeneingriffselement eine kammförmige gebogene Geometrie aufweist. Ein Mittelpunkt der Kreisbogenform des Gegeneingriffselements kann mit einer Drehachse der Tür übereinstimmen.More than one counter-engagement element can be provided. For example, a first counter-engagement element and a second counter-engagement element can be provided. As mentioned above, the counter-engagement element each has a plurality of counter-engagement hooks, so that the counter-engagement element has a comb-shaped, curved geometry. A center point of the circular arc shape of the counter-engagement element can coincide with an axis of rotation of the door.

Gemäß einer weiteren Ausführungsform ist das Gegeneingriffselement mit Hilfe einer Drehachse drehbar an der Haushalts-Geschirrspülmaschine angebracht.According to a further embodiment, the counter-engagement element is rotatably attached to the household dishwasher with the aid of an axis of rotation.

Eine Drehbewegung des Gegeneingriffselements um die Drehachse ist jedoch erschwert. Hierzu kann ein Dämpfer, beispielsweise ein Rotationsdämpfer, vorgesehen sein. Alternativ kann auch durch entsprechende Passungen der Drehachse die Drehbewegung des Gegeneingriffselements aufgrund von Reibung behindert werden. Hierdurch kann erreicht werden, dass dann, wenn die Vorspanneinrichtung beschädigt ist und das Eingriffselement in das Gegeneingriffselement eingreift, zwar die Tür blockiert ist, jedoch durch das Aufbringen einer erhöhten Kraft die Tür dennoch geöffnet werden kann. Hierdurch kann ein Benutzer auch bei einer Beschädigung der Vorspanneinrichtung Spülgut aus der Haushalts-Geschirrspülmaschine ausräumen.However, a rotational movement of the counter-engagement element about the axis of rotation is difficult. A damper, for example a rotary damper, can be provided for this purpose. Alternatively, the rotational movement of the counter-engagement element can also be hindered due to friction by appropriate fits of the axis of rotation. In this way it can be achieved that if the pretensioning device is damaged and the engagement element engages in the counter-engagement element, the door is blocked, but the door can still be opened by applying an increased force. In this way, a user can remove items to be washed from the domestic dishwasher even if the pretensioning device is damaged.

Gemäß einer weiteren Ausführungsform sind die Drehachse des Gegeneingriffselements und eine Drehachse der Tür koaxial angeordnet.According to a further embodiment, the axis of rotation of the counter-engagement element and an axis of rotation of the door are arranged coaxially.

Das heißt, die Drehachse des Gegeneingriffselements und die Drehachse der Tür stimmen überein. Alternativ kann die Drehachse des Gegeneingriffselements auch beabstandet von der Drehachse der Tür angeordnet sein.That is, the axis of rotation of the counter-engagement element and the axis of rotation of the door coincide. Alternatively, the axis of rotation of the counter-engagement element can also be arranged at a distance from the axis of rotation of the door.

Gemäß einer weiteren Ausführungsform ist das Gegeneingriffselement kreisförmig.According to a further embodiment, the counter-engagement element is circular.

Das Gegeneingriffselement ist insbesondere plattenförmig ausgebildet. An oder auf dem Gegeneingriffselement sind die insbesondere gekrümmten oder geraden Gegeneingriffshaken vorgesehen. Das Gegeneingriffselement kann beispielsweise ein Kunststoffspritzgussbauteil sein. Alternativ kann das Gegeneingriffselement auch aus einem Metallwerkstoff gefertigt sein.The counter-engagement element is designed in particular in the form of a plate. The counter-engagement hooks, in particular curved or straight, are provided on or on the counter-engagement element. The counter-engagement element can, for example, be a plastic injection-molded component. Alternatively, the counter-engagement element can also be made from a metal material.

Gemäß einer weiteren Ausführungsform umfasst die Vorspanneinrichtung ein Federelement und ein mit dem Federelement gekoppeltes Seil.According to a further embodiment, the pretensioning device comprises a spring element and a cable coupled to the spring element.

Das Seil kann beispielsweise ein Stahlseil oder ein Kunststoffseil sein. Das Federelement ist insbesondere eine Zylinderfeder. Vorzugsweise ist das Federelement eine Zugfeder.The rope can for example be a steel rope or a plastic rope. The spring element is in particular a cylinder spring. The spring element is preferably a tension spring.

Das Federelement unterstützt das Schließen der Tür. Allerdings ist eine Federkraft des Federelements so gering, dass sich die Tür nicht selbsttätig schließt.The spring element supports the closing of the door. However, the spring force of the spring element is so low that the door does not close automatically.

Gemäß einer weiteren Ausführungsform ist das Federelement mit einem Basisträger der Haushalts-Geschirrspülmaschine und das Seil mit dem Scharnier gekoppelt.According to a further embodiment, the spring element is coupled to a base support of the household dishwasher and the cable is coupled to the hinge.

Der Basisträger ist insbesondere ein kastenförmiges Kunststoffbauteil. Der Basisträger ist unterhalb des Spülbehälters angeordnet, wobei sich der Spülbehälter auf dem Basisträger abstützt. In dem Basisträger können elektronische Komponenten der Haushalts-Geschirrspülmaschine, wie beispielsweise eine Laugenpumpe, eine Umwälzpumpe, eine Steuereinrichtung oder dergleichen angeordnet sein. Vorzugsweise ist das Federelement mit einem Befestigungspunkt fest mit dem Basisträger verbunden. Das Federelement und das Seil können zumindest abschnittsweise innerhalb des Basisträgers angeordnet sein.The base support is in particular a box-shaped plastic component. The base support is arranged below the washing compartment, the washing compartment being supported on the base support. Electronic components of the household dishwasher, such as, for example, a drain pump, a circulation pump, a control device or the like, can be arranged in the base support. The spring element is preferably firmly connected to the base support with a fastening point. The spring element and the rope can be arranged at least in sections within the base support.

Gemäß einer weiteren Ausführungsform ist das Seil mit Hilfe des Eingriffselements mit dem Scharnier gekoppelt.According to a further embodiment, the rope is coupled to the hinge with the aid of the engagement element.

Das heißt, das Eingriffselement ist zwischen dem Seil und dem Scharnier, insbesondere dem Scharnierhebel des Scharniers, angeordnet. Das Eingriffselement verbindet somit das Seil mit dem Scharnier.That is, the engagement element is arranged between the cable and the hinge, in particular the hinge lever of the hinge. The engagement element thus connects the rope to the hinge.

Weitere mögliche Implementierungen der Haushalts-Geschirrspülmaschine umfassen auch nicht explizit genannte Kombinationen von zuvor oder im Folgenden bezüglich der Ausführungsbeispiele beschriebenen Merkmalen oder Ausführungsformen. Dabei wird der Fachmann auch Einzelaspekte als Verbesserungen oder Ergänzungen zu der jeweiligen Grundform der Haushalts-Geschirrspülmaschine hinzufügen.Further possible implementations of the household dishwasher also include combinations, not explicitly mentioned, of features or embodiments described above or below with regard to the exemplary embodiments.

The pretensioning device 19 only assists in closing the door 3. This includes the Biasing device 19, a spring element 20 and a cable 21 coupled to the spring element 20. The spring element 20 is, for example, a cylinder spring. In particular, the spring element 20 is a tension spring. The spring element 20 is designed such that it supports the closing of the door 3, but does not close it automatically. The rope 21 can be a steel rope or a plastic rope. The rope 21 can also be a composite rope. The pretensioning device 19 is coupled to the receiving section 18 of the pivot lever 17. The spring element 20 and the cable 21 can be received in the base support 15 at least in sections. In particular, the spring element 20 can be firmly connected to the base support 15.

Die Haushalts-Geschirrspülmaschine 1 umfasst ferner eine Arretiereinrichtung 22, die dazu eingerichtet ist, die Tür 3 bei einer Beschädigung der Vorspanneinrichtung 19, beispielsweise bei einem Reißen oder Brechen des Federelements 20 und/oder des Seils 21, zu arretieren, um ein selbsttätiges Verbringen der Tür 3 in den geöffneten Zustand Z1 zu verhindern. Das heißt, die Arretiereinrichtung 22 verhindert ein unkontrolliertes Öffnen der Tür 3 wenn diese entriegelt ist. Die Arretiereinrichtung 22 umfasst hierzu ein Arretierelement oder Eingriffselement 23, das mit dem Seil 21 verbunden ist. Insbesondere ist das Seil 21 mit Hilfe des Eingriffselements 23 mit dem Scharnierhebel 17 gekoppelt.The household dishwasher 1 further comprises a locking device 22, which is set up to lock the door 3 in the event of damage to the pretensioning device 19, for example if the spring element 20 and / or the cable 21 is torn or broken, in order to automatically move the To prevent door 3 in the open state Z1. That is to say, the locking device 22 prevents uncontrolled opening of the door 3 when it is unlocked. For this purpose, the locking device 22 comprises a locking element or engagement element 23 which is connected to the cable 21. In particular, the cable 21 is coupled to the hinge lever 17 with the aid of the engagement element 23.

Das Eingriffselement 23 umfasst einen Bolzenabschnitt 24, der drehbar in dem Aufnahmeabschnitt 18 des Scharnierhebels 17 eingehängt ist. Der Bolzenabschnitt 24 kann kreiszylinderförmig ausgebildet sein. Das Eingriffselement 23 ist keilförmig oder dreiecksförmig und läuft insbesondere ausgehend von dem Seil 21 in Richtung des Bolzenabschnitts 24 keilförmig zu. Das Seil 21 kann mit dem Eingriffselement 23 stoffschlüssig, formschlüssig und/oder kraftschlüssig verbunden sein. Beispielsweise ist das Seil 21 in das Eingriffselement 23 eingehängt oder mit diesem verklebt oder verklemmt. Das Eingriffselement 23 umfasst eine Vielzahl von Eingriffshaken 25, 26, von denen in der Fig. 3 jedoch nur zwei mit einem Bezugszeichen versehen sind. Die Eingriffshaken 25, 26 weisen in Richtung des Bolzenabschnitts 24. Insbesondere sind erste Eingriffshaken 25 und zweite Eingriffshaken 26 vorgesehen. Das Eingriffselement 23 bildet hierdurch eine tannenbaumförmige Geometrie aus.The engagement element 23 comprises a bolt section 24 which is rotatably suspended in the receiving section 18 of the hinge lever 17. The bolt section 24 can be designed in the shape of a circular cylinder. The engagement element 23 is wedge-shaped or triangular and, in particular, starting from the cable 21, tapers in a wedge-shaped manner in the direction of the bolt section 24. The cable 21 can be connected to the engagement element 23 with a material fit, form fit and / or force fit. For example, the cable 21 is suspended in the engagement element 23 or glued or clamped to it. The engagement element 23 comprises a plurality of engagement hooks 25, 26, of which in the Fig. 3 however, only two are provided with a reference number. The engagement hooks 25, 26 point in the direction of the bolt section 24. In particular, first engagement hooks 25 and second engagement hooks 26 are provided. The engagement element 23 thereby forms a fir tree-shaped geometry.

Die Arretiereinrichtung 22 umfasst weiterhin ein zu dem Eingriffselement 23 korrespondierendes, insbesondere erstes, Gegeneingriffselement 27. Das Gegeneingriffselement 27 ist feststehend an der Haushalts-Geschirrspülmaschine 1 angebracht. Das heißt, das Gegeneingriffselement 27 ist unbeweglich. Insbesondere ist das Gegeneingriffselement 27 kreisbogenförmig, insbesondere in Form eines Viertelkreises, ausgebildet und kann als Mittelpunkt die Drehachse 5 aufweisen. Das Gegeneingriffselement 27 umfasst eine Vielzahl zu den Eingriffshaken 25, 26 des Eingriffselements 23 korrespondierende Gegeneingriffshaken 28, von denen in der Fig. 3 jedoch nur einer mit einem Bezugszeichen versehen ist. Die Gegeneingriffshaken 28 können gekrümmt, oder wie in der Fig. 3 gezeigt, gerade sein. Die Gegeneingriffshaken 28 sind gleichsinnig zu den ersten Eingriffshaken 25 geneigt. Das Gegeneingriffselement 27 weist somit eine gekrümmte kammförmige Geometrie auf.The locking device 22 furthermore comprises a, in particular first, counter-engagement element 27 that corresponds to the engagement element 23. The counter-engagement element 27 is fixedly attached to the domestic dishwasher 1. That is, the counter-engagement element 27 is immovable. In particular, the counter-engagement element 27 is designed in the shape of a circular arc, in particular in the form of a quarter circle, and can have the axis of rotation 5 as the center. The counter-engagement element 27 comprises a plurality of the engagement hooks 25, 26 of the engagement element 23 corresponding counter-engagement hooks 28, of which in the Fig. 3 however, only one is provided with a reference number. The mating hooks 28 can be curved, or as in FIG Fig. 3 shown to be straight. The counter-engagement hooks 28 are inclined in the same direction as the first engagement hooks 25. The counter-engagement element 27 thus has a curved, comb-shaped geometry.

Optional kann die Arretiereinrichtung 22 ein weiteres, insbesondere ein zweites, Gegeneingriffselement 29, das ebenfalls kreisbogenförmig ausgebildet ist und das eine Vielzahl Gegeneingriffshaken 30 aufweist, umfassen. Die Gegeneingriffshaken 30 sind korrespondierend zu den zweiten Eingriffshaken 26 ausgebildet.Optionally, the locking device 22 can comprise a further, in particular a second, counter-engagement element 29, which is also designed in the shape of a circular arc and which has a plurality of counter-engagement hooks 30. The counter-engagement hooks 30 are designed to correspond to the second engagement hooks 26.

Das Eingriffselement 23 und insbesondere die Eingriffshaken 25, 26 des Eingriffselements 23 sind dazu eingerichtet, formschlüssig in die Gegeneingriffshaken 28, 30 der Gegeneingriffselemente 27, 29 einzugreifen. Dabei kann das Eingriffselement 23 entweder in das erste Gegeneingriffselement 27 oder in das zweite Gegeneingriffselement 29 eingreifen. Eine formschlüssige Verbindung entsteht durch das Ineinander- oder Hintergreifen von mindestens zwei Verbindungspartnern, in diesem Fall dem Eingriffselement 23 und dem entsprechenden Gegeneingriffselement 27, 29.The engaging element 23 and in particular the engaging hooks 25, 26 of the engaging element 23 are designed to engage in a form-fitting manner in the counter-engaging hooks 28, 30 of the counter-engaging elements 27, 29. The engagement element 23 can either engage in the first counter-engagement element 27 or in the second counter-engagement element 29. A form-fitting connection is created by the engagement of at least two connection partners, in this case the engagement element 23 and the corresponding counter-engagement element 27, 29.

Die Arretiereinrichtung 22 umfasst weiterhin ein Federelement 31, das das Eingriffselement 23 in Richtung des ersten Gegeneingriffselements 27 federvorspannt. Alternativ kann die Arretiereinrichtung 22 auch ein in der Fig. 3 nicht gezeigtes Federelement aufweisen, das das Eingriffselement 23 in Richtung des zweiten Gegeneingriffselements 29 federvorspannt. Das Federelement 31 umfasst einen an dem Scharnierhebel 17 vorgesehenen ersten Befestigungspunkt 32 sowie einen an dem Eingriffselement 23 vorgesehenen zweiten Befestigungspunkt 33.The locking device 22 furthermore comprises a spring element 31, which spring-biases the engagement element 23 in the direction of the first counter-engagement element 27. Alternatively, the locking device 22 can also be in the Fig. 3 have spring element, not shown, which spring-biases the engagement element 23 in the direction of the second counter-engagement element 29. The spring element 31 comprises a first fastening point 32 provided on the hinge lever 17 and a second fastening point 33 provided on the engagement element 23.

Das Federelement 31 spannt das Eingriffselement 23 so vor, dass dann, wenn eine Beschädigung der Vorspanneinrichtung 19 auftritt, beispielsweise wenn das Federelement 20 und/oder das Seil 21 reißt oder bricht, das Eingriffselement 23 um den Bolzenabschnitt 24 entgegen dem Uhrzeigersinn in einer Richtung R1 in Richtung des ersten Gegeneingriffselements 27 verschwenkt. Hierdurch geraten die ersten Eingriffshaken 25 des Eingriffselements 23 in formschlüssigen Eingriff mit den Gegeneingriffshaken 28 des ersten Gegeneingriffselements 27. Dadurch wird verhindert, dass sich die Tür 3 bei einem Entriegeln derselben unkontrolliert öffnet. Mit Hilfe eines Spezialwerkzeugs kann das Eingriffselement 23 anschließend wieder außer formschlüssigen Eingriff mit dem ersten Gegeneingriffselement 27 gebracht werden, so dass die Tür 3, beispielsweise zur Reparatur der Vorspanneinrichtung 19, wieder geöffnet werden kann.The spring element 31 prestresses the engagement element 23 so that if damage to the prestressing device 19 occurs, for example if the spring element 20 and / or the cable 21 tears or breaks, the engagement element 23 around the bolt section 24 counterclockwise in a direction R1 pivoted in the direction of the first counter-engagement element 27. As a result, the first engagement hooks 25 of the engagement element 23 come into positive engagement with the counter-engagement hooks 28 of the first counter-engagement element 27. This prevents the door 3 from opening in an uncontrolled manner when it is unlocked. With the aid of a special tool, the engagement element 23 can then be brought out of positive engagement with the first counter-engagement element 27 again, so that the door 3 can be opened again, for example to repair the pretensioning device 19.

Optional kann, wie zuvor schon erwähnt, alternativ zu dem Federelement 31 ein weiteres Federelement vorgesehen sein, das das Eingriffselement 23 in Richtung des zweiten Gegeneingriffselements 29 federvorspannt. Bei einer Beschädigung der Vorspanneinrichtung 19 verschwenkt das Eingriffselement 23 dann in einer Richtung R2 im Uhrzeigersinn in Richtung des zweiten Gegeneingriffselements 29, um in formschlüssigen Eingriff mit diesem zu geraten. Alternativ kann auch vollständig auf das Federelement 31 verzichtet werden. In diesem Fall wird das Eingriffselement 23 dann aufgrund seines Eigengewichts, das in einer Schwerkraftrichtung g wirkt, in Richtung des ersten Gegeneingriffselements 27 verschwenkt, um in formschlüssigen Eingriff mit diesem zu gelangen.Optionally, as already mentioned, a further spring element can be provided as an alternative to the spring element 31, which spring-preloads the engagement element 23 in the direction of the second counter-engagement element 29. If the pretensioning device 19 is damaged, the engaging element 23 then swivels in a clockwise direction R2 in the direction of the second counter-engaging element 29 in order to come into positive engagement therewith. Alternatively, the spring element 31 can also be completely dispensed with. In this case, the engagement element 23 is then pivoted in the direction of the first counter-engagement element 27 due to its own weight, which acts in a direction of gravity g, in order to come into positive engagement therewith.

Die Fig. 4 zeigt eine schematische Ansicht einer Ausführungsform des Eingriffselements 23. Bei dieser Ausführungsform des Eingriffselements 23 ist dieses aus einem Kunststoffmaterial gefertigt. Insbesondere ist das Eingriffselement 23 ein Kunststoffspritzgussbauteil. Hierdurch kann das Eingriffselement 23 kostengünstig hergestellt werden. Das Eingriffselement 23 umfasst einen Aufnahmeabschnitt 34, in den ein zylinderförmiger Endabschnitt 35 des Seils 21 aufnehmbar ist. Der Endabschnitt 35 ist beispielsweise an das Seil 21 angegossen oder angespritzt. Insbesondere kann der Endabschnitt 35 in den Aufnahmeabschnitt 34 eingeclipst oder eingeschnappt werden, um das Eingriffselement 23 mit dem Endabschnitt 35 formschlüssig zu verbinden.The Fig. 4 shows a schematic view of an embodiment of the engagement element 23. In this embodiment of the engagement element 23, this is made of a plastic material. In particular, the engagement element 23 is a plastic injection-molded component. As a result, the engagement element 23 can be manufactured inexpensively. The engagement element 23 comprises a receiving section 34, in which a cylindrical end section 35 of the cable 21 can be received. The end section 35 is cast or injection-molded onto the cable 21, for example. In particular, the end section 35 can be clipped or snapped into the receiving section 34 in order to connect the engagement element 23 to the end section 35 in a form-fitting manner.

Die Fig. 5 zeigt eine schematische Ansicht einer weiteren Ausführungsform des Eingriffselements 23. Bei dieser Ausführungsform des Eingriffselements 23 umfasst dieses einen aus einem Metallwerkstoff gefertigten Kern 36, der mit Hilfe einer Crimpverbindung 37 mit dem Seil 21 fest verbunden ist. Der Kern 36 ist beispielsweise mit Hilfe eines Kunststoffspritzgussverfahrens mit einem Kunststoffmaterial umspritzt, um das Eingriffselement 23 zu bilden. Der Bolzenabschnitt 24 kann dabei Teil des Kerns 36 sein.The Fig. 5 FIG. 11 shows a schematic view of a further embodiment of the engagement element 23. In this embodiment of the engagement element 23, the latter comprises a core 36 made of a metal material, which is firmly connected to the cable 21 with the aid of a crimp connection 37. The core 36 is encapsulated with a plastic material, for example with the aid of a plastic injection molding process, in order to form the engagement element 23. The bolt section 24 can be part of the core 36.

Die Fig. 6 zeigt eine schematische Ansicht einer weiteren Ausführungsform des Eingriffselements 23. Bei dieser Ausführungsform des Eingriffselements 23 umfasst das Eingriffselement 23 einen metallischen Kern 38, an dem die ersten Eingriffshaken 25 angeformt sind. Der Kern 38 ist jedoch unsymmetrisch ausgebildet, so dass das Eingriffselement 23 bei einer Beschädigung der Vorspanneinrichtung 19 aufgrund seines Eigengewichts in der Richtung R1 auf das erste Gegeneingriffselement 27 zu verschwenkt. Der Bolzenabschnitt 24 kann Teil des Kerns 38 sein. Die zweiten Eingriffshaken 26 des Eingriffselements 23 sind bei dieser Ausführungsform des Eingriffselements 23 verzichtbar. Das Eingriffselement 23 jedoch zusätzlich noch mit dem Federelement 31 kombiniert werden.The Fig. 6 shows a schematic view of a further embodiment of the engagement element 23. In this embodiment of the engagement element 23, the engagement element 23 comprises a metallic core 38 on which the first engagement hooks 25 are integrally formed. The core 38, however, is designed asymmetrically so that the engagement element 23 swivels towards the first counter-engagement element 27 in the direction R1 if the pretensioning device 19 is damaged due to its own weight. The bolt portion 24 can be part of the core 38. The second engagement hooks 26 of the engagement element 23 can be dispensed with in this embodiment of the engagement element 23. However, the engagement element 23 can also be combined with the spring element 31.

Die Fig. 7 zeigt eine stark vergrößerte Detailansicht einer Weiterbildung der Haushalts-Geschirrspülmaschine 1 mit Blick auf das Scharnier 16. Diese Ausführungsform der Haushalts-Geschirrspülmaschine 1 unterscheidet sich von der Ausführungsform der Haushalts-Geschirrspülmaschine 1 gemäß der Fig. 3 nur dadurch, dass nur ein Gegeneingriffselement 27, nämlich das erste Gegeneingriffselement 27, vorgesehen ist. Auf das zweite Gegeneingriffselement 29 wird verzichtet.The Fig. 7 shows a greatly enlarged detailed view of a further development of the domestic dishwasher 1 with a view of the hinge 16.

Die Drehachse 43 kann dabei koaxial zu der Drehachse 5 angeordnet sein. Alternativ können die Drehachsen 5, 43, wie in der Fig. 9 gezeigt, auch voneinander beabstandet angeordnet sein. Die Drehbarkeit des Gegeneingriffselements 42 um die Drehachse 43 ist jedoch beschränkt oder gedämpft. Das heißt, das Gegeneingriffselement 42 lässt sich nur schwer um die Drehachse 43 drehen. Dies kann beispielsweise durch das Vorsehen eines Dämpfers, insbesondere eines Rotationsdämpfers, oder durch eine entsprechende schwergängige Passung der Drehachse 43 und damit durch Reibung erreicht werden.The Fig. 9 shows a greatly enlarged detailed view of a further development of the domestic dishwasher 1 with a view of the hinge 16. In this embodiment of the domestic dishwasher 1, a counter-engagement element 42 in the form of a disk rotatable about an axis of rotation 43 is provided. The axis of rotation 43 can be arranged coaxially to the axis of rotation 5. Alternatively, the axes of rotation 5, 43, as in FIG Fig. 9 shown, also be arranged spaced from one another. The rotatability of the counter-engagement element 42 about the axis of rotation 43 is limited or attenuated. That is to say, the counter-engagement element 42 can only be rotated with difficulty about the axis of rotation 43. This can be achieved, for example, by providing a damper, in particular a rotary damper, or by a corresponding tight fit of the axis of rotation 43 and thus by friction.

Das Gegeneingriffselement 42 umfasst eine Vielzahl Gegeneingriffshaken 44, von denen in der Fig. 9 jedoch nur einer mit einem Bezugszeichen versehen ist. Die Gegeneingriffshaken 44 sind vorzugsweise bogenförmig gekrümmt. Allerdings können die Gegeneingriffshaken 44 auch gerade sein. Die ersten Eingriffshaken 25 des Eingriffselements 23 sind dazu eingerichtet, formschlüssig in die Gegeneingriffshaken 44 des Gegeneingriffselements 43 einzugreifen. Bei einer Beschädigung der Vorspanneinrichtung 19 verschwenkt das Eingriffselement 23 aufgrund seiner Federvorspannung mit Hilfe des Federelements 31 in der Richtung R1 entgegen dem Uhrzeigersinn auf das Gegeneingriffselements 42 zu, um mit diesem in formschlüssigen Eingriff zu geraten.The counter-engagement element 42 comprises a plurality of counter-engagement hooks 44, of which in the Fig. 9 however, only one is provided with a reference number. The counter-engagement hooks 44 are preferably curved in an arc shape. However, the counter-engagement hooks 44 can also be straight. The first engagement hooks 25 of the engagement element 23 are designed to engage in a form-fitting manner in the counter-engagement hooks 44 of the counter-engagement element 43. If the pretensioning device 19 is damaged, the engagement element 23 swivels due to its spring preload with the aid of the spring element 31 in the direction R1 counterclockwise towards the counter-engagement element 42 in order to come into positive engagement therewith.

Dadurch, dass das Gegeneingriffselement 42 um die Drehachse 43 drehbar ist, kann auch dann, wenn die Vorspanneinrichtung 19 beschädigt ist, die Tür 3 geöffnet werden. Hierdurch kann auch bei einer Beschädigung der Vorspanneinrichtung 19 beispielsweise noch Spülgut aus der Haushalts-Geschirrspülmaschine 1 ausgeräumt werden.Because the counter-engagement element 42 is rotatable about the axis of rotation 43, the door 3 can be opened even if the pretensioning device 19 is damaged. In this way, even if the pretensioning device 19 is damaged, items to be washed can still be removed from the domestic dishwasher 1, for example.

Aufgrund des Vorsehens der Arretiereinrichtung 22 kann auf kostenintensive und empfindliche elektronische Bauteile verzichtet werden. Es ist eine einfache Montage der Haushalts-Geschirrspülmaschine 1 möglich. Die Sicherheit wird signifikant erhöht, da die Tür 3 in allen ihren Positionen zuverlässig abgefangen wird. Eine Verletzung eines Benutzers wird dadurch zuverlässig verhindert.Due to the provision of the locking device 22, expensive and sensitive electronic components can be dispensed with. The household dishwasher 1 can be easily assembled. The security is significantly increased since the door 3 is reliably intercepted in all of its positions. This reliably prevents injury to a user.

Obwohl die vorliegende Erfindung anhand von Ausführungsbeispielen beschrieben wurde, ist sie vielfältig modifizierbar.Although the present invention has been described on the basis of exemplary embodiments, it can be modified in many ways.
