Abstract

The dosing unit, for detergent (7) at a dishwasher, has a chamber (1) with a control to feed it into the washer for the cleaning cycle. The consistency of the detergent is assessed, to register whether a solid tablet (8) is in the chamber, using a pressure switch (6) with a coupling (5) to a moving pin (3).

Description

Die vorliegende Erfindung betrifft ein Dosiergerät für einen Geschirrspüler nach dem Oberbegriff des Anspruches 1.The The present invention relates to a dosing device for a dishwasher the preamble of claim 1.

Es sind Geschirrspüler bekannt, bei denen eine Dosierkammer zur Aufnahme des Reinigungsmittels vorgesehen ist. In die Dosierkammer wird je nach Anwender pulverförmiges, flüssiges, gelförmiges oder festes Reinigungsmittel eingefügt. Während des Spülablaufes wird dann die Dosierkammer geöffnet, damit die Spülflotte mit Reinigungsmittel versetzt wird. Bisher wird nicht unterschieden, welche Konsistenz das Reinigungsmittel besitzt. Insbesondere bei Spülprogrammen mit kurzen Haltezeiten kann dies zu Problemen führen, weil festes Reinigungsmittel in Form von Reinigungstabletten aufgrund der zur Auflösung benötigten Zeit sich gegebenenfalls nicht vollständig auflöst, was das Reinigungsergebnis nachteilig beeinflusst. Denn bei Programmen mit kurzen Haltezeiten können solche Reinigungstabletten nicht ihre volle Leistung entfalten, wenn sie nicht vollständig aufgelöst werden. Pulver hingegen löst sich besonders schnell auf und kann daher auch bei kurzen Spülprogrammen gut eingesetzt werden.It are dishwashers known, in which a metering chamber for receiving the cleaning agent is provided. Depending on the user, powdered, liquid, gel-like or solid detergent inserted. During the flushing process then the dosing chamber is opened, so that the rinsing liquor is mixed with cleaning agent. So far, no distinction is made what consistency the cleaning agent has. Especially with rinse programs with short hold times, this can cause problems because of solid detergent in the form of cleaning tablets due to the time required for dissolution may not be complete dissolves, which adversely affects the cleaning result. Because with programs with short holding times can such cleaning tablets do not unfold their full potential, if not complete disbanded become. Powder dissolves Be particularly quick and can therefore even with short wash programs be used well.

Aus der DE 101 45 601 A1 ist ein Dosiergerät für Geschirrspüler bekannt, bei dem ein Sensor zur Erkennung der Form und/oder der Art eines der Spülflüssigkeit zuzugebenden Spülmittels vorgesehen ist. Als Sensor ist ein Leitfähigkeitssensor vorgesehen.From the DE 101 45 601 A1 a metering device for dishwashers is known in which a sensor is provided for detecting the shape and / or the type of rinsing liquid to be added to the rinsing agent. As a sensor, a conductivity sensor is provided.

Die FR 2 873 444 A1 offenbart eine Messvorrichtung, welche mit Hilfe eines Piezoelements die Konsistenz von Reinigungsmitteln erfasst.The FR 2 873 444 A1 discloses a measuring device which detects the consistency of cleaning agents with the aid of a piezoelectric element.

Es ist daher Aufgabe der vorliegenden Erfindung ein Dosiergerät für einen Geschirrspüler zu schaffen, mittels dem der Programmablauf im Hinblick auf das verwendete Reinigungsmittel optimiert werden kann.It Therefore, an object of the present invention is a metering device for a dishwasher by means of which the program sequence with regard to the used cleaning agent can be optimized.

Diese Aufgabe wird mit einem Dosiergerät mit den Merkmalen des Anspruches 1 gelöst.These Task is with a dosing with the features of claim 1 solved.

Erfindungsgemäß umfasst das Dosiergerät Mittel zur Erfassung der Konsistenz des Reinigungsmittels, bei denen ein Druckschalter vorgesehen ist, mittels dem ein Festkörper als Reinigungsmittel, wie eine Reinigungstablette erfassbar ist. Denn die Reinigungstablette kann aufgrund ihrer Gewichtskraft den Druckschalter betätigen, während pulverförmiges, flüssiges oder gelförmiges Reinigungsmittel eine Betätigung des Druckschalters nicht vornehmen kann, da keine ausreichende Gewichtskraft auf einem mit dem Druckschalter gekoppelten Stift lastet.According to the invention the dosing device means for detecting the consistency of the detergent in which a Pressure switch is provided by means of a solid as Detergent as a cleaning tablet is detected. Because The cleaning tablet can, due to its weight, the pressure switch actuate, while powdered, liquid or gel-like Cleaning agent an actuation of the pressure switch can not make, because no sufficient weight on a pin coupled to the pressure switch.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen:The Invention will be described below with reference to an embodiment with reference to the attached Drawings closer explained. Show it:

1 eine schematische Ansicht einer erfindungsgemäßen Dosierkammer mit pulverförmigen Reinigungsmittel; 1 a schematic view of a metering chamber according to the invention with powdered detergent;

2 eine schematische Ansicht der Dosierkammer der 1 mit einem festen Reinigungsmittel. 2 a schematic view of the dosing of 1 with a solid detergent.

Eine Dosierkammer 1 umfasst einen Aufnahmebehälter mit einem Boden 2, an dem ein Stift 3 beweglich gelagert ist. Der Stift 3 ragt in die Dosierkammer 1 hinein und ist nach oben hin mit einer Spitze 4 versehen. Der Stift 3 ist über ein Kopplungselement 5 mit einem Druckschalter 6 verbunden. In der Dosierkammer 1 ist in dem Ausführungsbeispiel der 1 ein pulverförmiges Reinigungsmittel 7 enthalten, das auf dem Boden 2 aufliegt. Die über dem Stift 3 angeordnete Menge an Reinigungsmittel 7 reicht nicht aus, um mit ihrer Gewichtskraft den Stift 3 gegen die Kraft des Druckschalters 6 nach unten zu drücken, so dass die Steuerung davon ausgeht, dass ein pulverförmiges, flüssiges oder gelförmiges Reinigungsmittel in der Dosierkammer 1 enthalten ist, das sich vergleichsweise schnell auflösen lässt.A dosing chamber 1 includes a receptacle with a bottom 2 on which a pen 3 is movably mounted. The pencil 3 protrudes into the dosing chamber 1 in and is up with a tip 4 Mistake. The pencil 3 is via a coupling element 5 with a pressure switch 6 connected. In the dosing chamber 1 is in the embodiment of 1 a powdered detergent 7 included that on the ground 2 rests. The above the pen 3 arranged amount of detergent 7 is not enough to use their weight to the pin 3 against the force of the pressure switch 6 Press down so that the controller assumes that a powdered, liquid or gel detergent in the dosing chamber 1 is included, which can be resolved relatively quickly.

In 2 ist in der Dosierkammer 1 statt dem pulverförmigen Reinigungsmittel ein festes Reinigungsmittel 8 in Form einer Tablette eingefügt. Da das Reinigungsmittel 8 in fester Form vorliegt, drückt die gesamte Gewichtskraft des festen Reinigungsmittels 8 auf die Spitze 4 des Stiftes 3, so dass dieser nach unten gedrückt wird und über die Kopplung 5 den Druckschalter 6 betätigt. Der Druckschalter 6 ist in der geschlossenen Position und gibt an die Steuerung das Signal, dass in der Dosierkammer 1 ein festes Reinigungsmittel 8 enthalten ist, das eine längere Zeit für die Auflösung benötigt.In 2 is in the dosing chamber 1 instead of the powdery detergent a solid detergent 8th inserted in the form of a tablet. As the cleaning agent 8th in solid form, pushes the entire weight of the solid detergent 8th on top 4 of the pen 3 so that it is pressed down and over the coupling 5 the pressure switch 6 actuated. The pressure switch 6 is in the closed position and gives the signal to the controller that is in the dosing chamber 1 a solid detergent 8th is included, which takes a longer time for the resolution.
