Due to small horizontal guide width, skewings are effectively prevented.

Description

Einspülschale für eine Waschmaschine Dishwasher bowl for a washing machine
Die vorliegende Erfindung betrifft eine Einspülschale zum Einschub in die Einschuböffnung einer Waschmaschine nach dem Oberbegriff von Patentanspruch 1 sowie eine Waschmaschine.The present invention relates to a induction bowl for insertion into the insertion opening of a washing machine according to the preamble of claim 1 and a washing machine.
Einspülschalen für Waschmaschinen sind aus dem Stand der Technik bekannt. Solche Einspülschalen dienen zur Aufnahme von Waschmittel, welches pulver- förmig oder flüssig sein kann. Das Waschmittel wird vor oder während des Waschvorgangs in die Einspülschale gegeben und von dort mittels Zufuhr von Frischwasser in den Laugenbehälter der Waschmaschine eingespült. Typischerweise ist eine Einspülschale in mehrere Kammern durch Trennwände unterteilt, wobei die Kammern z.B. zur Aufnahme von Waschmittel für den Vorwasch- und Hauptwaschgang bzw. für den Weichspüler vorgesehen sind.Detergent pans for washing machines are known from the prior art. Such induction bowls are used to hold detergent, which can be powdery or liquid. The detergent is placed in the dispenser bowl before or during the washing process and from there it is flushed into the washing machine tub by supplying fresh water. Typically, a induction bowl is divided into several compartments by partitions, the compartments e.g. are provided to hold detergent for the prewash and main wash cycle or for the fabric softener.
Aus dem Stand der Technik bekannte und als Schubladen ausgebildete Einspül- schalen weisen gegenüber der Einschuböffnung in der Waschmaschine eine relative große Toleranz auf. Diese Toleranz ist erforderlich, da Einspülschalen im Allgemeinen als Kunststoffspritzgussteil hergestellt werden. Solche relativ großen Spritzgussteile lassen sich bei vertretbarem Aufwand nur mit relativ großen Toleranzen herstellen. Die Toleranz zwischen der Einspülschublade und den entspre- chenden Führungselementen der Einschuböffnung der Waschmaschine soll aber möglichst klein sein, damit ein Verkanten der Einspülschale während des Einschubvorgangs in die Waschmaschine verhindert werden.Detergent dishes known from the prior art and designed as drawers have a relatively large tolerance with respect to the insertion opening in the washing machine. This tolerance is necessary because induction bowls are generally manufactured as plastic injection molded parts. Such relatively large injection molded parts can only be produced with relatively large tolerances with reasonable effort. However, the tolerance between the induction drawer and the corresponding guide elements of the insertion opening of the washing machine should be as small as possible so that the induction bowl cannot be tilted during the insertion process into the washing machine.
Nachteilig hierbei ist, dass ein solches Verkanten auch bei vertretbar engen Toleranzen im Allgemeinen nur wirksam vermieden wird, wenn die durch den Benutzer der Waschmaschine zum Einschieben der Einspülschale ausgeübte Einschubkraft in etwa in der Mitte der Frontseite der Einspülschale ansetzt, der Benutzer die Einspülschale also etwa in der Mitte der Frontseite anfasst. Drückt der Benutzer hingegen auf einen außermittigen Bereich der Einspülschale - bei technisch ungebildeten Benutzern häufig -, um diese in die Einschuböffnung einzuschieben, so kommt es auch bei relativ kleinen Toleranzen noch zu einem Verkanten.The disadvantage here is that such canting is generally only effectively avoided, even with tolerably narrow tolerances, if the insertion force exerted by the user of the washing machine to insert the induction bowl starts approximately in the middle of the front of the induction bowl, that is to say the user places the induction bowl approximately in the middle of the front. If, on the other hand, the user presses an eccentric area of the induction bowl - frequently in the case of technically uneducated users - in order to insert it into the insertion opening, canting occurs even with relatively small tolerances.
Der Erfindung liegt die Aufgabe zu Grunde, eine verbesserte Einspülschale für eine Waschmaschine und eine verbesserte Waschmaschine zu schaffen. Diese der Erfindung zu Grunde liegende Aufgabe wird durch die Merkmale der unabhängigen Patentansprüche gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Patentansprüchen angegeben. Nach der Erfindung werden die horizontale und die vertikale Führung der Einspülschale in zwei voneinander getrennte Bereiche aufgeteilt: Beispielsweise dient die äußere Kante der Einspülschale zur vertikalen Führung, während in einem mittleren Bereich der Einspülschale eine Führung in horizontaler Richtung vorgesehen ist. Dies erlaubt es, das seitliche Spiel zwischen der Einspülschale und der Einschuböffnung zu minimieren, um so ein Verkanten auch bei außermittigem Einleiten der Einschubkraft in die Einspülschale während des Einschubvorgangs zu verhindern.The invention is based on the object of providing an improved induction bowl for a washing machine and an improved washing machine. This object on which the invention is based is achieved by the features of the independent claims. Preferred embodiments are specified in the dependent claims. According to the invention, the horizontal and vertical guidance of the induction bowl are divided into two separate areas: for example, the outer edge of the induction bowl serves for vertical guidance, while a guide in the horizontal direction is provided in a central area of the induction bowl. This allows the lateral play between the induction bowl and the insertion opening to be minimized, in order to prevent tilting even when the insertion force is introduced off-center into the induction bowl during the insertion process.
Besonders vorteilhaft ist es, wenn die horizontale Führung der Einspülschale über eine hintere Begrenzung der Einspülschale hinwegragt, so dass bei einer Einschubbewegung der Einspülschale in die Einschuböffnung der Waschmaschine zunächst die überragende horizontale Führung der Einspülschale mit den entsprechenden Führungselementen in der Einschuböffnung zur Wirkung kommt. Auf diese Art und Weise ist eine relativ große Führungslänge der horizontalen Füh- rungselemente der Einschuböffnung und der Einspülschale während des Einschubvorgangs gewährleistet, und zwar bei gleichzeitig geringer Führungsbreite der horizontalen Führungselemente. Die Toleranz zwischen Einspülschale und Einschuböffnung in horizontaler Richtung ist deshalb enger einstellbar, was einem Verkanten auch beim Einschieben der Einspülschale durch Drücken auf einen seitlichen Bereich der Frontplatte der Einspülschale entgegenwirkt.It is particularly advantageous if the horizontal guidance of the induction bowl protrudes beyond a rear boundary of the induction bowl, so that when the induction bowl is pushed into the insertion opening of the washing machine, the outstanding horizontal guidance of the induction bowl with the corresponding guide elements in the insertion opening first comes into effect. In this way, a relatively long guide length of the horizontal guide elements of the insertion opening and of the induction bowl is ensured during the insertion process, and at the same time the guide width of the horizontal guide elements is narrow. The tolerance between the induction bowl and the insertion opening in the horizontal direction can therefore be adjusted more narrowly, which counteracts tilting even when the induction bowl is pushed in by pressing on a lateral region of the front plate of the induction bowl.
In einer weiteren bevorzugten Ausführungsform sind die Trennwände der mittleren Kammer der Einspülschale als horizontale Führungselemente ausgebildet. Dazu können diese Wände auch nach oben etwas über den Rand der Kammer hinaus ragen. Bei der mittleren Kammer handelt es sich typischerweise um die Kammer für ein Weichspülmittel. Die beiden Trennwände dieser Kammer sind in einem oberen Bereich jeweils über eine hintere Begrenzung der Einspülschale hinausgezogen und greifen beim Einschieben der Einspülschale in entsprechende Führungselemente in der Einschuböffnung der Waschmaschine ein. Die Führungselemente der Waschmaschine weisen dabei vorzugsweise eine Einfädelungshilfe auf, die zum Beispiel trichterförmig ausgebildet sein kann.In a further preferred embodiment, the partitions of the middle chamber of the induction bowl are designed as horizontal guide elements. For this purpose, these walls can also protrude slightly above the edge of the chamber. The middle chamber is typically the chamber for a fabric softener. The two partition walls of this chamber are each drawn in an upper region beyond a rear boundary of the induction bowl and engage in corresponding guide elements in the insertion opening of the washing machine when the induction bowl is inserted. The guide elements of the washing machine preferably have a threading aid, which can be funnel-shaped, for example.
In einer weiteren bevorzugten Ausführungsform sind zumindest die Trennwände der mittleren Kammer der Einspülschale doppelwandig ausgebildet. Dies hat den Vorteil einer größeren Stabilität der durch die Trennwände realisierten horizontalen Führung. Durch die doppelwandige Ausführung wird aber auch eine größere Stabilität und geringere Verformbarkeit der Trennwände und des gesamtenIn a further preferred embodiment, at least the partitions of the middle chamber of the induction bowl are double-walled. This has the advantage of greater stability of the horizontal guidance realized by the partition walls. The double-walled design also results in greater stability and less deformability of the partitions and of the whole
Schubladenkörpers erreicht, so dass bei unsymmetrisch eingeleiteten Schubkräf- ten keine schädliche Verformung der Schublade auftreten kann, die zu einer Verkantung beitragen könnte. Ein weiterer Vorteil der doppelwandigen Ausbildung der Trennwände ist, dass die Trennwände nicht wellig wirken, sondern ein hochwertiges Aussehen haben. Damit verbunden ist eine gesteigerte Wertanmutung der Waschmaschine insgesamt.Reached drawer body, so that with asymmetrically initiated thrust no harmful deformation of the drawer can occur, which could contribute to tilting. Another advantage of the double-walled design of the partitions is that the partitions do not look wavy, but have a high-quality appearance. This is associated with an increased perceived value of the washing machine as a whole.

The induction drawer 3 has chambers 6, 7 and 8 for receiving detergents or fabric softeners. The chambers 6, 7 and 8 are formed by the partitions 9 and 10 in the induction drawer 3. To insert the induction drawer 3 into the insertion opening 2 of its receiving housing are between the side walls 23 of the induction drawer 3 and Side walls 24 of the receiving housing are arranged guide rails, not shown in detail, which serve to guide the insertion movement both in the horizontal and in the vertical direction.
Dies führt zu der großen Führungsbreite T, die den gesamten Öffnungsbereich der Einschuböffnung 2 abdeckt. Andererseits führt zu dies bei ausgezogenerThis leads to the large guide width T, which covers the entire opening area of the insertion opening 2. On the other hand, this leads to being pulled out

Fig. 3 zeigt eine schematische Darstellung einer Ausführungsform einer erfindungsgemäßen Einspülschublade in einer Ansicht von oben. Die Einspülschublade 3 genäß Fig. 3 weist in deren Randbereichen 11 und 12 jeweils Führungen für die Führung der Einspülschublade in vertikaler Richtung auf. Diese Führungen greifen in entsprechende Führungselemente in der Einschuböffnung 2 ein, wie aus Fig. 4 zu ersehen ist und anhand Fig. 4 näher erläutert werden wird.Fig. 3 shows a schematic representation of an embodiment of an induction drawer according to the invention in a view from above. The induction drawer 3 according to FIG. 3 has guides in the edge regions 11 and 12 for guiding the induction drawer in the vertical direction. These guides engage in corresponding guide elements in the insertion opening 2, as can be seen from FIG. 4 and will be explained in more detail with reference to FIG. 4.
Zur horizontalen Führung hat die Einspülschublade 3 in deren Zentralbereich Führungen, die durch Oberkanten der Trennwände 9 und 10 gebildet werden. Die Trennwände 9 und 10 ragen in dem Bereich 13 über die hintere Begrenzung derFor horizontal guidance, the induction drawer 3 has guides in its central area which are formed by upper edges of the partition walls 9 and 10. The partitions 9 and 10 protrude in the area 13 beyond the rear boundary of the
Einspülschublade 3 hinaus. Im korrespondierenden oberen Bereich der Einschuböffnung 2 befinden sich Führungselemente 14 und 15. Zum Einschub der Einspülschublade 3 in die Einschuböffnung 2 wird zunächst der überstehende Bereich 13 der Trennwände 9 und 10 zwischen die Führungselemente 14 und 15 gebracht und kann dann zwischen diesen Führungselementen hin- und hergeschoben werden.Detergent drawer 3. Guide elements 14 and 15 are located in the corresponding upper area of the insertion opening 2.

Die Führungselemente 14 und 15 begrenzen dabei zusammen mit den Trennwänden 9 und 10 das Spiel in horizontaler Richtung und zwar bei einer geringen Führungsbreite t und einer dazu relativ großen Führungslänge L. Dadurch werden Verkantungen wirksam vermieden, selbst wenn die Einschubkraft nicht zentral sondern über einen seitlichen Bereich der Frontplatte 4 der Einspülschublade 3 eingeleitet wird.The guide elements 14 and 15, together with the partitions 9 and 10, limit the play in the horizontal direction, specifically with a small guide width t and a relatively large guide length L.

Between the cover plate 20 of the receiving housing behind the insertion opening 2 and its guide rails 18 and 19, guide spaces are formed, in which the rails 16 and 17 run for vertical guidance during the longitudinal movement of the detergent drawer 3.
Dadurch wird die Lage der Einspülschublade 3 in vertikaler Richtung festgelegt.This fixes the position of the induction drawer 3 in the vertical direction.
Die Trennwand 9 und die Trennwand 10 der Einspülschublade 3 greifen in den Raum zwischen den Führungen 14 und 15 des Aufnahmegehäuses hinter der Einschuböffnung 2 ein, womit die Lage der Einspülschublade 3 in horizontaler Richtung festgelegt ist. Die Trennwände 9 und 10 sind doppelwandig ausgebildet; dies hat den Vorteil einer größeren mechanischen Steifigkeit. Ferner wird auch das sonst übliche wellige Aussehen der Trennwände in der Einspülschublade vermieden; es ergibt sich ein hochwertiger Eindruck.The partition 9 and the partition 10 of the induction drawer 3 engage in the space between the guides 14 and 15 of the receptacle behind the insertion opening 2, whereby the position of the induction drawer 3 is fixed in the horizontal direction. The partitions 9 and 10 are double-walled; this has the advantage of greater mechanical rigidity. Furthermore, the otherwise usual wavy appearance of the partitions in the induction drawer is avoided; it gives a high quality impression.
Im Ausführungsbeispiel der Fig. 5 weisen die Führungen 14 und 15 für die Ein- spülschublade 3 Endbereiche 21 bzw. 22 auf, die mit den Führungen 14 und 15 einen Winkel bilden, so dass eine trichterförmige Erweiterung der Einführungsöffnung entsteht. Dadurch ist eine Einfädelungshilfe für den gegenseitigen Eingriff der Führungselemente, der Trennwände 9 und 10 sowie der Führungen 14 und 15, realisiert. Die perspektivische Ansicht einer Einspülschale gemäß Fig. 6 zeigt ein weiteres bevorzugtes Ausführungsbeispiel, bei dem die Endbereiche 21 und 22 der Führungen auf einer Länge 13 über die hintere Begrenzung der Einspülschublade 3 hinausragen. Zum leichteren Einfädeln sind die Endbereiche 21 und 22 der Trennwände 9 und 10 nach unten hin abgeschrägt. In Fig. 7 ist in perspektivischer Ansicht eine aus der Einschuböffnung 2 des Aufnahmegehäuses nach vorn ausgezogene Einspülschublade 3 gezeigt. In the exemplary embodiment in FIG. 5, the guides 14 and 15 for the induction drawer 3 have end regions 21 and 22, respectively, which form an angle with the guides 14 and 15, so that a funnel-shaped widening of the insertion opening is created. As a result, a threading aid for the mutual engagement of the guide elements, the partitions 9 and 10 and the guides 14 and 15 is realized. 6 shows a further preferred exemplary embodiment, in which the end regions 21 and 22 of the guides protrude over a length 13 beyond the rear boundary of the induction drawer 3. For easier threading, the end regions 21 and 22 of the partitions 9 and 10 are chamfered downwards. 7 shows a perspective view of a dispenser drawer 3 which is pulled out of the insertion opening 2 of the receiving housing.
