Description

Die Erfindung betrifft eine Dosiervorrichtung für Wasch- und/oder Spülmittel zum Einbau in ein Fenster einer Tragwand, beispiels­weise der Innenwand der Beschickungstüre einer Geschirrspül­maschine, wobei das Fenster der Tragwand eine Randverstärkung oder einen Durchzug in Gestalt eines nach innen abgekanteten Randstreifens aufweist und die Dosiervorrichtung gegliedert ist in eine Außenpartie, die sich mit einem eine Dichtung auf­weisenden Auflageflansch an der Außenseite der Fensterumrandung anlegt, und in eine Einschubpartie, welche die Tragwand durchsetzt.The invention relates to a metering device for detergents and / or dishwashing agents for installation in a window of a supporting wall, for example the inner wall of the loading door of a dishwasher, the window of the supporting wall having an edge reinforcement or a passage in the form of an inwardly bent edge strip and the metering device is structured is in an outer part, which lies on the outside of the window border with a bearing flange with a seal, and in a slide-in part, which passes through the supporting wall.

Dosiervorrichtungen dieser Art, die vorzugsweise aus Kunststoff bestehen, sind bislang mit Hilfe von Schrauben befestigt worden. Hierbei sind Stützringe aus Blech vorgesehen, welche die Ein­schubpartie der Dosiervorrichtung locker umgeben und auf die dem Türhohlraum zugewandte Innenseite der Fensterumrandung aufgelegt werden. Diese Stützringe - oder in anderen Fällen einzelne Stützpratzen - werden an den Dosiervorrichtungen festgeschraubt und drücken somit den Auflageflansch mit seinem ringsum laufenden Dichtungsring an die Außenseite der Fensterumrandung heran.Dosing devices of this type, which are preferably made of plastic, have so far been fastened with the aid of screws. Here, support rings made of sheet metal are provided, which loosely surround the insertion part of the metering device and are placed on the inside of the window border facing the door cavity. These support rings - or in other cases individual support claws - are screwed onto the metering devices and thus press the support flange with its all-round sealing ring against the outside of the window frame.

Er erfordert eine erhebliche Anpreßkraft, um auch bei fertigungs­bedingten Unebenheiten der Tragwand den Dichtungsring auf ganzer Länge ausreichend zu verformen und so die Abdichtung sicherzu­stellen. Insbesondere im Hinblick auf dieses Dichtungsproblem glaubte man, auf Schrauben nicht verzichten zu können.It requires a considerable contact pressure in order to sufficiently deform the sealing ring over its entire length, even in the event of unevenness in the supporting wall, and thus ensure the seal. In view of this sealing problem in particular, it was believed that screws could not be dispensed with.

Deshalb wurden bislang in der Hausgerätefertigung die Dosier­vorrichtungen von Hand montiert, was bei üblicherweise vier bis sechs Schrauben pro Vorrichtung einen nicht unerheblichen Kosten­faktor darstellt.For this reason, the dosing devices have so far been assembled by hand in household appliance production, which is a not inconsiderable cost factor with typically four to six screws per device.

Der Erfindung liegt die Aufgabe zugrunde, den Einbau von Dosier­vorrichtungen in Fenster von Tragwänden bei Hausgeräten zu vereinfachen und so zu gestalten, daß selbsttätige Manipulatoren, d. h. Fertigungsroboter hierfür zum Einsatz kommen können.The invention has for its object to simplify the installation of metering devices in windows of supporting walls in household appliances and to design such that automatic manipulators, d. H. Manufacturing robots can be used for this.

Diese Aufgabe wird ausgehend von einer Dosiervorrichtung der ein­leitend bezeichneten Art erfindungsgemäß dadurch gelöst, daß an den Seitenflächen der Einschubpartie sich elastisch abspreizende Stützzungen angebracht sind, deren Stirnflächen sich an der Innenkante des Fensters abstützen und bezüglich der Spreiz­richtung nach innen geneigt sind. Diese Stützzungen werden vorzugsweise gleich bei der Herstellung des Kunstoffgehäuses der Dosiervorrichtung mitangeformt. Üblicherweise hat der für das Gehäuse verwendete Kunststoff eine ausreichende Elastizität und Dauerfließfestigkeit. Wenn die Einschubpartie der Dosiervor­richtung in das Tragwandfenster eingesetzt wird, legt sich der Rand des Fensterausschnitts über die Stützzungen und drückt diese unter elastischer Verformung so weit an die Seitenfläche der Einschubpartie an, daß diese in das Fenster eindringen kann. Sobald aber das Ende der Stützzungen die Fensterinnenkante, bei einer Blechtragwand insbesondere die innere Kante des Durchzugs, passiert, versuchen sich die Stützzungen aufzuspreizen, wobei ihre zur Spreizrichtung geneigten Stirnflächen sich verkeilen und nach einer begrenzten Spreizbewegung sich fest an den Kanten abstützen. Dabei kann es von Vorteil sein, wenn sich die scharfen Blechkanten in die Stützflächen eindrücken, wodurch sich eine kräftige und vibrationssichere Abstützung ergibt.This object is achieved on the basis of a metering device of the type described in the introduction in that elastically spreading supporting tongues are attached to the side surfaces of the insertion part, the end faces of which are supported on the inner edge of the window and are inclined inwards with respect to the direction of expansion. These support tongues are preferably molded on during the manufacture of the plastic housing of the metering device. The plastic used for the housing usually has sufficient elasticity and permanent flow resistance. When the insertion part of the metering device is inserted into the supporting wall window, the edge of the window cutout lies over the supporting tongues and presses them against the side surface of the insertion part with elastic deformation so that it can penetrate into the window. However, as soon as the end of the support tongues passes the inside edge of the window, in particular the inner edge of the passage in the case of a sheet-metal support wall, the support tongues try to spread out, their end faces inclined to the direction of expansion becoming wedged and, after a limited expansion movement, firmly attached to the edges support. It can be advantageous if the sharp sheet metal edges press into the support surfaces, which results in a strong and vibration-proof support.

Dabei ist es von größter Bedeutung und ausschlaggebendem Vorteil, daß die Stützzungen sich immer weiter aufspreizen, je größer die auf die Dosiervorrichtung in Einbaurichtung ausgeübte Kraft ist. Zweckmäßigerweise sind die Stirnflächen der Stützzungen in Spreizrichtung - gegebenenfalls durch Abwinkelung der Stütz­zungenenden - breiter als der Stützzungenquerschnitt im übrigen. Die Stirnflächen passen sich infolge der Keilwirkung selbsttätig den gegebenen Verhältnissen an und lassen kein Zurückfedern zu. Dadurch werden unumgängliche Fertigungstoleranzen, unter anderen hinsichtlich der Höhe der Durchzüge, ohne Schwierigkeiten aufgenommen.It is of the greatest importance and decisive advantage that the support tongues spread ever wider, the greater the force exerted on the metering device in the installation direction. The end faces of the support tongues are expediently wider in the spreading direction - if necessary by angling the ends of the support tongue - than the rest of the support tongue cross section. The end faces adapt themselves automatically to the given conditions due to the wedge effect and do not allow springing back. As a result, unavoidable manufacturing tolerances, including the height of the draw-throughs, can be accommodated without difficulty.

Um genügend hohe Stützkräfte aufnehmen zu können und trotzdem elastisch spreizbar zu sein, haben die Stützzungen vorzugsweise einen in Umfangsrichtung der Einschubpartie verlaufenden läng­lichen Querschnitt, beispielsweise einen rechteckigen Bandquer­schnitt. Die normalerweise ebenen oder leicht balligen Stirn­flächen können in Spreizrichtung gestuft ausgebildet sein, um trotz dosierbarer Stützkraft bei unterschiedlich hohen Durchzügen deren Kanten einen festen Sitz an den Stirnflächen zu geben.In order to be able to absorb sufficiently high supporting forces and still be elastically spreadable, the supporting tongues preferably have an elongated cross section running in the circumferential direction of the insertion section, for example a rectangular band cross section. The normally flat or slightly spherical end faces can be designed stepped in the direction of expansion in order to give their edges a firm fit on the end faces despite the meterable supporting force with differently high pull-throughs.

Je nach der Gestaltung des Auflageflansches und der Seitenflächen der Dosiervorrichtung kann es zweckmäßig sein, die Stützzungen hakenförmig auszubilden in der Weise, daß sie von der Verbin­dungsstelle mit der Seitenfläche ausgehend sich zunächst etwa senkrecht zur Seitenfläche des Kunststofformteils erstrecken und dann zum Auflageflansch hin um etwa 90° gebogen sind. Um die Stützkräfte in den Gehäusekörper einzuleiten, können von den Stützzungen nach innen verlaufende Führungsrippen an der Einschubpartie angeformt sein. Diese schrägen Rippen bewirken eine Zentrierung der Einschubpartie im Fensterausschnitt, indem sie beim Einfügen über die Fensterränder gleiten.Depending on the design of the support flange and the side surfaces of the metering device, it may be expedient to design the support tongues in a hook shape in such a way that, starting from the point of connection with the side surface, they initially extend approximately perpendicular to the side surface of the molded plastic part and then to the support flange by approximately 90 ° are bent. In order to introduce the supporting forces into the housing body, guide ribs running inward from the supporting tongues can be formed on the insertion part. These oblique ribs center the slide-in section in the window cutout by sliding over the window edges when inserted.

Es ist somit möglich, unter Einsatz selbsttätiger Manipulatoren Dosiervorrichtungen oder andere gegenüber der Tragwand abzu­dichtende Komponenten voll selbsttätig in die betreffenden Maschinen dicht einzubauen. Die Geräte werden einfach mit der Einschubpartie voraus in die Fensterausschnitte eingedrückt und krallen sich von selbst fest.It is thus possible, using automatic manipulators, to install dosing devices or other components to be sealed against the supporting wall fully automatically in the machines in question. The devices are simply pushed into the window cut-outs with the slide-in section ahead and grip themselves by themselves.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Im einzelnen zeigt

  • Fig. 1 einen Teilschnitt I-I des Gehäuses eines Klarspülmittel-­Dosiergeräts etwa im Maßstab 2,5 : 1,
  • Fig. 2 einen Horizontalschnitt II-II einer Eckpartie des Geräts nach Fig. 1 und
  • Fig 3 eine teilweise Seitenansicht des Geräts nach Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. In detail shows
  • 1 is a partial section II of the housing of a rinse aid dispenser approximately on a scale of 2.5: 1,
  • Fig. 2 is a horizontal section II-II of a corner portion of the device of FIG. 1 and
  • 3 is a partial side view of the device of FIG. 1st

Das dargestellte Gehäuse, dessen Innenaufbau im einzelnen nicht gezeigt ist, besteht aus einer Außenpartie 1, die durch Spiegel­schweißung entlang einer Schweißnaht 2 mit einer Innenpartie 3 verschweißt ist. Die Außenpartie ist für die Hausfrau zugänglich, wenn das Gerät, wie gezeigt, in das dem Spülraum zugewandte Innenblech 4 der Beschickungstür einer Geschirrspülmaschine eingebaut ist. Die Angaben "außen" und "innen" beziehen sich somit auf den Türinnenraum, in welchem sich die Innenpartie 3 befindet.The housing shown, the inner structure of which is not shown in detail, consists of an outer part 1 which is welded to an inner part 3 by mirror welding along a weld seam 2. The outer part is accessible to the housewife when the device, as shown, is installed in the inner panel 4 of the loading door of a dishwasher facing the wash cabinet. The information "outside" and "inside" thus refer to the interior of the door in which the inner part 3 is located.

Gegenüber dem mit der Innenpartie 3 verschweißten Abschnitt der Außenpartie 1 ist der Außenabschnitt verbreitert und bildet einen Auflageflansch, der in einer umlaufenden Nut 5 einen Dichtungs­ring 6 aufnimmt und mit einer Leiste 7 auf dem Innenblech 4 auf­liegt. An den geraden Abschnitten wird der Dichtungsring zwischen der Leiste 7 und einzelnen kleinen Rippen 8 gehalten.Compared to the section of the outer section 1 welded to the inner section 3, the outer section is widened and forms a support flange which receives a sealing ring 6 in a circumferential groove 5 and rests on the inner sheet 4 with a strip 7. At the straight sections, the sealing ring is held between the strip 7 and individual small ribs 8.

An der Seitenfläche der Innenpartie 3 sitzen hakenförmige Stütz­zungen 9 an, die dem Auflageflansch zu abgewinkelt sind. An den freien Enden weisen diese Stützzungen 9 eine verbreiterte, treppenförmig abgestufte Stirnfläche 10 auf, die in Fig. 1 durch eine strichpunktierte Linie verdeutlicht ist. Die Stützzunge 9 läßt sich im Sinne einer Schwenkbewegung elastisch verformen. Die Tangente des Schwenkbogens ist eingezeichnet und mit einem von der Innenpartie wegführenden Pfeil bezeichnet. Zu dieser sogenannten Spreizrichtung 11 ist die Stirnfläche 10 nach innen geneigt.On the side surface of the inner part 3 sit hook-shaped support tongues 9, which are angled to the support flange. At the free ends, these support tongues 9 have a widened, stepped end face 10, which is illustrated in FIG. 1 by a dash-dotted line. The support tongue 9 can be elastically deformed in the sense of a pivoting movement. The tangent of the swivel arc is shown and marked with an arrow leading away from the inner part. The end face 10 is inclined inwards to this so-called expansion direction 11.

An der in Fig. 1 oberen gewölbten Fläche der Stützzunge 9 setzt eine Führungsrippe 12 an, die nach innen und zur Innenpartie 3 hin schräg ausläuft. Das Innenblech 4, welches die Tragwand für das beschriebene Gehäuse bildet, hat einen nach innen abge­kanteten Durchzug 13, auf dessen Kante die Stützzunge 9 aufsteht.A guide rib 12 attaches to the curved surface of the supporting tongue 9 in FIG. 1, which tapers out at an angle towards the inside and towards the inner part 3. The inner plate 4, which forms the supporting wall for the housing described, has an inwardly bent passage 13, on the edge of which the supporting tongue 9 stands up.

Das Einsetzen des beschriebenen Gehäuses erfolgt gem. Fig. 1 von unten her mit der Innenpartie 3 voraus. Der Dichtring 6 ist in die Nut 5 eingefügt. Zunächst ergibt sich eine gewisse Führung oder Zentrierung dadurch, daß der Rücken der Führungsrippe 12 über die dazu querstehende Biegekante des Innenblechs 4 gleitet. Wenn die Stützzungen 9, die mit einem gegenseitigen Abstand von etwa 3 cm über den Umfang der Innenpartie verteilt sind, mit dem Innenblech in Berührung kommen, verformen sie sich, wie in Fig. 1 strichpunktiert eingezeichnet, und gleiten mit der Außenkante der Stirnfläche 10 am Durchzug 13 entlang. Im weiteren Verlauf der Einsetzbewegung wird eine erhebliche Kraft aufgewendet, so daß die Biegekante des Innenblechs 4 den Dichtring 6 quetscht und schließlich die Leiste 7 außen auf dem Innenblech 4 zur Anlage kommt. Die Stützzungen 9 sind so angeordnet, daß in dieser Stellung die Kante der Stirnfläche 10 über den Durchzug hinausgewandert ist, so daß die Stützzunge 9 sich ein wenig aufspreizen kann. Dabei kommt freilich eine der Stufen der Stirnfläche 10 an der Kante des Durchzugs 13 zum Anschlag. In dieser Stellung ruht die Stützzunge 9 auf dem Durchzug 13 auf und bewirkt eine sichere und haltbare Verriegelung oder Verklammerung des Gehäuses im Tragblech. Die Stützkräfte werden auch über die Führungsrippen 12 in das Gehäuse eingeleitet.The housing described is inserted in accordance with. Fig. 1 from below with the inner part 3 ahead. The sealing ring 6 is inserted into the groove 5. First of all, a certain guidance or centering results from the fact that the back of the guide rib 12 slides over the transverse bending edge of the inner plate 4. When the support tongues 9, which are distributed at a mutual distance of about 3 cm over the circumference of the inner part, come into contact with the inner sheet, they deform, as shown in dash-dotted lines in FIG. 1, and slide with the outer edge of the end face 10 on Passage 13 along. In the further course of the insertion movement, a considerable force is applied, so that the bending edge of the inner plate 4 squeezes the sealing ring 6 and finally the bar 7 comes to rest on the inner plate 4. The support tongues 9 are arranged so that in this position the edge of the end face 10 has migrated beyond the passage, so that the support tongue 9 can spread out a little. Of course, one of the levels of End face 10 at the edge of the passage 13 to the stop. In this position, the support tongue 9 rests on the passage 13 and brings about a secure and durable locking or clamping of the housing in the support plate. The supporting forces are also introduced into the housing via the guide ribs 12.

Zum eventuellen Wiederausbau ist als Hilfswerkzeug ein starrer Rahmen vorgesehen, dessen lichter Querschnitt der Fensteröffnung entspricht. Dieser nicht gezeigte Rahmen wird von innen her über die Stützzungen 9 gestülpt, wodurch diese in die strichpunktiert gezeichnete Stellung zurückgezwängt werden, so daß sich das Gehäuse herausnehmen läßt.For possible dismantling, a rigid frame is provided as an auxiliary tool, the clear cross-section of which corresponds to the window opening. This frame, not shown, is slipped from the inside over the support tongues 9, as a result of which these are forced back into the position shown in broken lines, so that the housing can be removed.
