Definitions
- the invention relates to a device for feeding detergents in dishwashers using a metering chamber arranged on the inside of a hinged loading door, which can be closed by a hinged lid with a controllable trigger mechanism, the metering chamber being in two parts and the one chamber part having an effective one in the operating position Outlet opening is provided.
- DE-OS 35 03 336 it is known to use a detergent dispenser for this purpose, which is equipped with two metering chambers and in which one of the metering chambers is emptied via an outlet opening when the loading door is closed so that the cleaning medium falls along the inside of the loading door into the washing container.
- the cleaning agent gets into the sump of the machine and is therefore washed out and pumped out before the pre-rinse cycle when the softener is backwashed. If the device is operated improperly, especially if the loading door is closed quickly or suddenly, the cleaning agent not only falls too far into the machine, it may also be blown by the air jam that occurs and thus undesirably distributed.
- the object of the invention is to improve a device of the known type such that the cleaning agent for the pre-rinse cycle is only added when the loading door is closed and is therefore introduced into the machine in a targeted manner. This avoids loss of cleaning agents and also prevents the cleaning agent from being improperly distributed.
- the technical effort should be kept low and the operation should be simple. In particular, additional electromechanical elements for opening metering chambers should be avoided.
- the object is achieved in a device of the type mentioned above in that the outlet opening is covered by a closure which is designed as a partial element of the hinged cover.

Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Zuführen von Reinigungsmitteln bei Geschirrspülern unter Verwendung einer an der Innenseite einer klappbaren Beschickungstüre angeordneten Dosierkammer, die durch einen Klappdeckel mit steuerbarem Auslösemechanismus schließbar ist, wobei die Dosierkammer zweiteilig ausgebildet und der eine Kammerteil mit einer in der Betriebsstellung wirksamen Auslauföffnung versehen ist.The invention relates to a device for feeding detergents in dishwashers using a metering chamber arranged on the inside of a hinged loading door, which can be closed by a hinged lid with a controllable trigger mechanism, the metering chamber being in two parts and the one chamber part having an effective one in the operating position Outlet opening is provided.
Bei Geschirrspülern ist es allgemein üblich, mit einem sog. Einlaugenverfahren zu arbeiten, d.h. das Reinigungsmittel wird aus einer Dosierkammer nach Lösen einer Verschlußklappe nur dem Hauptspülgang zugegeben. Der diesem Hauptspülgang vorhergehende Vorspülgang wurde meist ohne Zugabe von Spülmitteln durchgeführt. Nun hat sich gezeigt, daß man ein besseres Ergebnis bekommt, wenn man schon im Vorspülgang geeignete Spülmittel zugibt. Hierfür ist es bekannt, zusätzlich zum Auffüllen der Dosierkammer in die Maschine vor dem Vorspülgang Spülmittel z.B. am Rand des Behälterbodens zuzugeben. Da diese Art nicht sehr bedienungsfreundlich ist, wurden auch schon zusätzliche Dosierbehälter vorgesehen, aus denen das Reinigungsmittel in den Spüler fällt und damit für den Vorspülgang zur Verfügung steht.It is common practice in dishwashers to work with a so-called lye process, i.e. the detergent is only added to the main wash cycle from a dosing chamber after loosening a flap. The pre-rinse cycle preceding this main wash cycle was usually carried out without the addition of detergents. It has now been shown that you can get a better result if you add suitable detergent in the pre-wash cycle. For this it is known, in addition to filling the dosing chamber into the machine before the pre-rinse cycle, detergent e.g. add at the edge of the container bottom. Since this type is not very user-friendly, additional dosing containers have already been provided, from which the detergent falls into the dishwasher and is therefore available for the pre-rinse cycle.
Gemäß der DE-OS 35 03 336 ist es bekannt, hierfür einen Reinigungsmittelgeber einzusetzen, der mit zwei Dosierkammern ausgestattet ist und bei dem die eine der Dosierkammern beim Schließen der Beschickungstüre über eine Auslaßöffnung so geleert wird, daß das Reinigungs mittel an der Innenseite der Beschickungstüre entlang in den Spülbehälter fällt.According to DE-OS 35 03 336, it is known to use a detergent dispenser for this purpose, which is equipped with two metering chambers and in which one of the metering chambers is emptied via an outlet opening when the loading door is closed so that the cleaning medium falls along the inside of the loading door into the washing container.
Bei dieser bekannten Ausführungsform wird zwar weitgehend vermieden, daß das Reinigungsmittel bis in den Sumpf der Maschine gelangt und damit bereits vor dem Vorspülgang beim Rückspülen des Enthärters ausgewaschen und abgepumpt wird. Bei unsachgemäßer Bedienung des Gerätes, insbesondere bei einem schnellen oder gar schlagartigen Schließen der Beschickungstüre, fällt aber das Reinigungsmittel nicht nur zu weit in die Maschine, es wird durch den auftretenden Luftstau ggf. auch verblasen und damit unerwünscht verteilt.In this known embodiment it is largely avoided that the cleaning agent gets into the sump of the machine and is therefore washed out and pumped out before the pre-rinse cycle when the softener is backwashed. If the device is operated improperly, especially if the loading door is closed quickly or suddenly, the cleaning agent not only falls too far into the machine, it may also be blown by the air jam that occurs and thus undesirably distributed.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der bekannten Art dahingehend zu verbessern, daß das Reinigungsmittel für den Vorspülgang erst bei geschlossener Beschickungstüre zugegeben und damit gezielt in die Maschine eingebracht wird. Damit werden Verluste an Reinigungsmitteln vermieden und es wird auch vermieden, daß das Reinigungsmittel unsachgemäß verteilt wird. Dabei soll der technische Aufwand gering gehalten und die Bedienung einfach gestaltet sein. Insbesondere sollen zusätzliche elektromechanische Elemente zum Öffnen von Dosierkammern vermieden werden.The object of the invention is to improve a device of the known type such that the cleaning agent for the pre-rinse cycle is only added when the loading door is closed and is therefore introduced into the machine in a targeted manner. This avoids loss of cleaning agents and also prevents the cleaning agent from being improperly distributed. The technical effort should be kept low and the operation should be simple. In particular, additional electromechanical elements for opening metering chambers should be avoided.
Gemäß der Erfindung wird bei einer Vorrichtung der eingangs angegebenen Art die gestellte Aufgabe dadurch gelöst, daß die Auslauföffnung durch einen Verschluß abgedeckt ist, der als Teilelement des Klappdeckels ausgebildet ist.According to the invention, the object is achieved in a device of the type mentioned above in that the outlet opening is covered by a closure which is designed as a partial element of the hinged cover.
Der für die Auslauföffnung vorgesehene Verschluß wird vorteilhaft so ausgebildet, daß er z.B. nach Art eines Pendels an der Klappe für die Dosierkammer befestigt und so gelagert ist, daß die Verschlußöffnung nur in der Betriebslage der Beschickungstüre geöffnet bzw. durch das Spülmittel aufgedrückt wird.The closure provided for the outlet opening is advantageously designed such that it is fastened, for example in the manner of a pendulum, to the flap for the metering chamber and is mounted such that the closure opening is only in the Operating position of the loading door is opened or pressed open by the detergent.
Da das Spülmittel Feuchtigkeit aufnehmen und zum Teil auch klebrig werden kann, ist es vorteilhaft, den Verschluß mit einem in den Bereich eines Sprühstrahles des Spülers ragenden Prallteil zu versehen, so daß der Verschluß durch den Sprühstrahl zwangsweise auch bei leichter Verklebung geöffnet und die Dosierkammer durch den Sprühstrahl ausgespült wird.Since the detergent can absorb moisture and can also become sticky in some cases, it is advantageous to provide the closure with a baffle protruding into the area of a spray jet of the dishwasher, so that the closure is forced open by the spray jet even with slight adhesion and the metering chamber is through the spray jet is rinsed out.
Anhand der Zeichnung sei ein Ausführungsbeispiel der Erfindung beschrieben und die Wirkungsweise erläutert.An exemplary embodiment of the invention is described and the mode of operation explained with reference to the drawing.
Die Fig. 1 zeigt eine Vorrichtung zum Zuführen von Reinigungsmitteln bei Geschirrspülern, wie sie üblicherweise in der Tiefe von Beschickungstüren montiert sind.1 shows a device for supplying detergents to dishwashers, as is usually installed in the depth of loading doors.
Die Fig. 2 zeigt in Seitenansicht, zum Teil im Schnitt, eine die Dosierkammer abschließende Klappe mit einem integrierten Verschluß für die Auslauföffnung der zweiten Dosierkammer.2 shows a side view, partly in section, of a flap closing the metering chamber with an integrated closure for the outlet opening of the second metering chamber.
Die Dosierkammer nach der Erfindung besteht aus einem Unterteil 1, in das die Kammern 2 und 3 eingeformt sind. Mit dem Unterteil 1 ist über Scharnierböcke 4 ein Klappdeckel 5 verbunden, der durch eine nicht gezeichnete Feder in der Offenstellung gehalten wird. Der Klappdeckel 5 trägt an seiner Innenseite einen Dichtrahmen 6, der mit dem Rand der Dosierkammer 2 übereinstimmt und diese im geschlossenen Zustand abdichtet. In den Klappdeckel 5 ist ferner eine Ausnehmung 7 eingearbeitet, durch die hindurch ein Riegel 8 den Klappdeckel 5 in der geschlossenen Stellung halten kann. Der Riegel 8 kann durch geeignete Steuerelemente, wie Zugmagnete oder Bimetallstreifen, ausgelöst werden, so daß die nicht gezeichnete Feder den Klappdeckel 5 in die Offenstellung bringen kann.The dosing chamber according to the invention consists of a
In den Klappdeckel 5 ist ferner eine Öffnung 9 eingearbeitet, die der Kammer 3 zugeordnet ist und durch die das in die Kammer 3 eingefüllte Reinigungsmittel in der Betriebslage entlang der Innenfläche der Beschickungstüre auslaufen kann, wenn der Verschluß 10 die Öffnung 9 freigegeben hat. Der Verschluß 10 ist in einem Gelenk 11 am Klappdeckel 5 wie ein Pendel gelagert, so daß er mit seinem abgewinkelten Teil 12 bei geschlossener Dosierkammer die Öffnung 9 dann verschließt, wenn die Beschickungstüre nicht in der Senkrechten steht.In the
Wird die Beschickungstüre des Spülers in die senkrechte Betriebslage gebracht, dann schwenkt der Verschluß 10 aus und gibt die Öffnung 9 so weit frei, daß das in der Kammer 3 lagernde Reinigungsmittel auslaufen kann.If the loading door of the dishwasher is brought into the vertical operating position, the
Diese Öffnungsbewegung des Verschlußes 10 wird durch das Gewicht des Reinigungsmittels unterstützt.This opening movement of the
In Fig. 2 ist ein Klappdeckel 5 gezeigt, der an den Scharnierböcken 4 mit einem angeformten Lagerteil 13 gehaltert ist. In die Deckelfläche 14 ist ein Lagerzapfen 15 eingesetzt, an dem der Verschluß 10 schwenkbar gehaltert ist. Die Auslauföffnung 9 wird durch das abgewinkelte Teil 12 dann geschlossen gehalten, wenn sich die Beschickungstüre außerhalb der senkrechten Lage befindet. Zweckmäßig wird das abgewinkelte Teil 12 mit einer Zusatzmasse 16 ausgestattet, damit der Verschluß 10 leichter in die Öffnungslage verschwenkt. Am Teil 10 ist ein Prallteil 17 angeformt, das, von einem Sprühstrahl beaufschlagt, die Öffnungsbewegung unterstützt und damit einem Sprühstrahl auch die Möglichkeit gibt, über die Öffnung 9 die Kammer 3 auszuspülen.In Fig. 2, a
