Abstract

In the device, a nozzle plate is used, the boreholes of which, being directed towards the wall of metering containers, are produced in that in each case two blind boreholes running in opposite directions and parallel to the axis are arranged so as to be offset in the desired spraying direction. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einspülvorrichtung für Waschmaschinen und dgl. bestehend aus einem mit dem Wasseranschluß verbundenen und mit Wasserkammern versehenen Träger zur Aufnahme mindestens eines oben offenen Waschmittelbehälters, aus dem das Waschmittel über deckseitig im Träger angeordnete, gerichtete Wasserdüsen in den Laugenbehälter ausspülbar ist.The invention relates to a induction device for washing machines and the like. Consists of a support connected to the water connection and provided with water chambers for receiving at least one detergent container open at the top, from which the detergent can be rinsed out into the detergent solution container via directed water nozzles arranged on the cover side in the support.

Für die Zuführung von Wasch- und Pflegemitteln zum Laugenbehälter einer Waschmaschine werden Einspül-Vorrichtungen benutzt, die aus einem Träger, sowie vorzugsweise einschiebbaren, die Waschmittel aufnehmende Dosierbehälter bestehen. Der Träger für diese meist wannenförmigen Dosierbehälter ist deckseitig als Hohlkörper ausgebildet, an den der Wasserzulauf z.B. über eine Wasserweiche angeschlossen ist. Der Träger hat düsenförmige Auslaßöffnungen so daß mit dem Wasserzulauf, die im Dosierbehälter lagernden Waschmittel in den Laugenbehälter ausgespült werden.For the supply of detergents and care products to the suds container of a washing machine, induction devices are used, which consist of a carrier, as well as preferably insertable dosing containers that hold the detergent. The carrier for these mostly trough-shaped dosing containers is designed on the top side as a hollow body to which the water inlet e.g. is connected via a water switch. The carrier has nozzle-shaped outlet openings so that with the water inlet, the detergents stored in the dosing container are rinsed out into the tub.

Es ist wesentlich, daß das Ausspülen der Waschmittel nicht nur einigermaßen gleichmäßig, sondern auch vollständig erfolgt. Zu diesem Zweck müssen die Wasserdüsen so gerichtet sein, daß die Wandungen der Dosierbehälter und vor allem die meist abgerundeten Kehlen gut bespült werden. Hierfür ist es bekannt, in die deckseitigen Trägerwandungen düsenförmige Bohrungen einzubringen, deren Achsen gegen die Wandungen und Kehlen der Waschmittel-Dosierbehälter gerichtet sind. Da diese Träger meist aus Kunststoff hergestellt sind, müssen für die Bohrungen in den Spritzwerkzeugen entsprechende Schieber vorgesehen werden, die außerordentlich aufwendig sind.It is essential that the detergents are not only rinsed out to a certain extent, but also completely. For this purpose, the water nozzles must be directed so that the walls of the dosing container and especially the mostly rounded throats are well washed. For this purpose, it is known to make nozzle-shaped bores in the cover-side support walls, the axes of which are directed against the walls and grooves of the detergent dosing containers. Since these carriers are usually made of plastic, corresponding slides must be provided for the holes in the injection molds, which are extremely complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Lösung anzugeben, die es ermöglicht die gerichteten Wasserdüsen in Formteile z.B. aus Kunststoff mit relativ einfachen Werkzeugen einzubringen.The invention has for its object to provide a solution that enables the directed water nozzles in molded parts e.g. made of plastic with relatively simple tools.

Gemäß der Erfindung wird dies bei einer Einspülvorrichtung dadurch erreicht, daß zumindest ein Teil der Wasserdüsen dadurch schräg gegen die Wandungsteile der Wanne gerichtet ist, daß in der Trägerwandung, für jede Düse zwei Sacklochbohrungen gegenläufig und achsparallel eingebracht sind, die gegeneinander mit weniger als dem Bohrungsdurchmesser in der gewünschten Sprührichtung versetzt sind.According to the invention, this is achieved with a induction device in that at least some of the water nozzles are directed obliquely against the wall parts of the tub in that two blind holes for each nozzle are made in opposite directions and axially parallel in the support wall, which are mutually less than the bore diameter are offset in the desired spray direction.

Anhand schematischer Zeichnungen wird ein Ausführungsbeispiel der Erfindung beschrieben.

  • Die Figur 1 zeigt eine Einspülvorrichtung im Schnitt,
  • die Figur 2 zeigt eine Deckplatte mit den eingeformten Wasserdüsen,
  • die Figur 3 zeigt einen vergrößerten Schnitt durch eine deckseitige Trägerwandung.
An exemplary embodiment of the invention is described on the basis of schematic drawings.
  • FIG. 1 shows a induction device in section,
  • FIG. 2 shows a cover plate with the molded water nozzles,
  • FIG. 3 shows an enlarged section through a carrier wall on the deck side.

Die Einspülvorrichtung besteht aus einem Träger 1 der seitlich mit Führungen 2 versehen ist, in die schubkastenartig Dosierbehälter 3 eingeschoben sind. Der Träger 1 umschließt die Behälter 3 bodenseitig und ist mit einem, nicht gezeichneten, zum Laugenbehälter einer Waschmaschine führenden Auslauf versehen. Der Träger 1 bildet zusammen mit einer Platte 4 einen Hohlraum 5 in den über Einlaßstutzen 6 und einem vorgeschalteten Ventil 7 Wasser eingedrückt wird. Das Wasser strömt über die Düsen 8 und 9 in Behälter 3 und spült das dort liegende Waschmittel 10 in den Laugenbehälter aus.The induction device consists of a carrier 1 which is laterally provided with guides 2 into which metering containers 3 are inserted in a drawer-like manner. The carrier 1 encloses the container 3 on the bottom and is provided with an outlet (not shown) leading to the washing machine tub. The carrier 1 forms, together with a plate 4, a cavity 5 into which water 7 is pressed via the inlet nozzle 6 and an upstream valve. The water flows through the nozzles 8 and 9 into container 3 and rinses the detergent 10 there into the tub.

Es ist ersichtlich, daß die düsenförmigen Bohrungen 8 senkrecht nach unten und die Bohrungen 9 gcgen die Wandung 11 bzw. die Kehlen 12 gerichtet sind.It can be seen that the nozzle-shaped bores 8 are directed vertically downwards and the bores 9 gcgen the wall 11 or the throats 12.

Aus Figur 2 ist nun in Verbindung mit Figur 3 ersichtlich, daß die Schrägstellung der Düsen 9 im Träger 1 nicht als Schrägbohrungen ausgeführt, sondern durch gegenläufig eingebrachte Sacklochbohrungen 13, 14 gewonnen sind, deren Achsen parallel liegen und die jeweils um weniger als einem Bohrungsdurchmesser in Richtung der gewünschten Sprührichtung versetzt angebracht sind. Aus Figur 2 ist dabei ersichtlich, daß das Versetzen nach jeder gewünschten Richtung erfolgen kann.From FIG. 2 it can now be seen in connection with FIG. 3 that the inclination of the nozzles 9 in the carrier 1 is not designed as inclined bores, but is obtained by counter-bored blind holes 13, 14, the axes of which are parallel and which are each less than one bore diameter in Direction of the desired spray direction are attached offset. From Figure 2 it can be seen that the displacement can take place in any desired direction.

Die Sacklochbohrungen können ohne Verwendung von Schiebern, beim Spritzgießen von Kunststoffteilen geformt werden. Die Neigung des Wasserstrahles aus den Düsenöffnungen wird durch entsprechendes Versetzen der Sacklöcher gegeneinander bestimmt. Die Lage der Sacklöcher gegeneinander bestimmt die Sprührichtung. Durch Verwendung unterschiedlicher Durchmesser kann auch noch die Sprühmenge an die gewünschte Verteilung angepaßt werden.The blind holes can be formed without the use of slides when injection molding plastic parts. The inclination of the water jet from the nozzle openings is determined by correspondingly offset the blind holes. The position of the blind holes against each other determines the spray direction. By using different diameters, the spray quantity can also be adapted to the desired distribution.
