Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erfassung des Füllstandes in einem Haushaltsgerät gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device to record the level in a home appliance according to the generic term of claim 1.
Eine gattungsgemäße Vorrichtung zur Messung
des Füllstandes

ist aus
Ferner ist aus
Die Aufgabe der vorliegenden Erfindung besteht darin, eine verbesserte Vorrichtung zur Erfassung des Füllstandes in einem Haushaltsgerät bereitzustellen.The object of the present invention is an improved device for detecting the level in a home appliance provide.
Die Aufgabe der Erfindung wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.The object of the invention is achieved by solved the features of claim 1. Advantageous further developments are specified in the dependent claims.
Gemäß der Erfindung ist ein Messeinsatz vorgesehen, der ein isolierendes Trägerelement aufweist, auf dem mehrere Elektroden nebeneinander angeordnet sind. Auf diese Weise lässt sich ein einfacher Aufbau realisieren, welcher mit geringem Aufwand hergestellt werden kann und sich darüber hinaus weitgehend miniaturisieren lässt. Außerdem ist die Möglichkeit gegeben, den Messeinsatz an die Bauform eines Flüssigkeitsbehälters anzupassen.According to the invention, a measuring insert is provided which is an insulating support element has, on which a plurality of electrodes are arranged side by side. That way realize a simple structure, which with little effort can be produced and also largely miniaturized leaves. Moreover is the possibility given to adapt the measuring insert to the design of a liquid container.
In einer bevorzugten Ausführungsform ist das isolierende Trägerelement als elastische Folie, vorzugsweise lebensmittelechte Kunststofffolie, ausgebildet. Die hieraus gewonnene Flexibilität ermöglicht den Einsatz der Vorrichtung in Behältern mit variablen Formen und Geometrien. Der Messeinsatz kann beispielsweise an gekrümmte Flächen eines Behälters angepasst werden.In a preferred embodiment is the insulating support element as an elastic film, preferably food-safe plastic film, educated. The flexibility gained from this enables the device to be used in containers with variable shapes and geometries. The measuring insert can, for example on curved surfaces a container be adjusted.
Gemäß einer weiteren bevorzugten Ausführungsform sind die Elektroden als Leiterbahnen unterschiedlicher Länge ausgebildet. Dieser Messeinsatz kann deshalb mit einem in der Industrie sehr gängigen Verfahren, dem Heißprägeverfahren, hergestellt werden. Beim Heißprägen wird eine Kupferfolie mit haftvermittelnder Schicht unter Druck und Temperatur mit Hilfe eines Prägestempels, auf dem das Leiterbahnbild dargestellt ist, auf ein Substrat gepresst. Der Einsatz dieses Verfahrens eröffnet die Möglichkeit einer schnellen und wirtschaftlichen Herstellung der beschriebenen Ausführungsform.According to another preferred embodiment the electrodes are designed as conductor tracks of different lengths. This measuring insert can therefore be carried out using a method that is very common in industry, the hot stamping process, getting produced. When hot stamping a copper foil with adhesive layer under pressure and temperature with the help of a stamp, on which the conductor track image is shown, pressed onto a substrate. The use of this procedure opens up the possibility a quick and economical production of the described Embodiment.
Eine weitere bevorzugte Ausführungsform besteht in der Verwendung einer Schutzschicht, welche die Elektroden umgibt. Die Schutzschicht soll insbesondere beständig sein gegen säurehaltige Flüssigkeiten, wie sie beispielsweise Kalklösemittel darstellen. Reinigungsmittel dieser Art werden in Haushaltsgeräten eingesetzt um Kalkablagerungen aufzulösen. Ein Angreifen der Elektroden durch die in den Kalklösemitteln enthaltenen Säuren wird durch die Schutzschicht verhindert. Ferner soll die Schicht eine Schutzwirkung gegen basenhaltige Flüssigkeiten wie beispielsweise Seifenlaugen bieten. Bevorzugt ist es weiterhin, dass die Schutzschicht elektrisch leitfähig ist und aus einem Edelmetall, vorzugsweise Gold, besteht.Another preferred embodiment exists using a protective layer that surrounds the electrodes. The protective layer should in particular be resistant to acidic ones Liquids, such as descaling agents represent. Cleaning agents of this type are used in household appliances to dissolve limescale. The electrodes in the lime solvents attack the electrodes contained acids is prevented by the protective layer. Furthermore, the layer a protective effect against liquids containing bases such as Provide soapy water. It is further preferred that the protective layer is electrically conductive and consists of a noble metal, preferably gold.
Vorzugsweise weist der Messeinsatz ein Rohr auf, welcher das Trägerelement mit den Elektroden enthält, wodurch eine platzsparende Geometrie ermöglicht wird. Auch kann ein nach dieser Ausführungsform hergestellter Messeinsatz in verschiedenen Flüssigkeitsbehältern unterschiedlicher lateraler Ausdehnung verwendet werden.The measuring insert preferably has a tube on which the carrier element with the electrodes contains which enables a space-saving geometry. Also one can according to this embodiment manufactured measuring insert in different liquid containers different lateral extent can be used.
In einer weiteren bevorzugten Ausführungsform ist ein zusätzlicher Messbehälter vorgesehen, in welchem der Messeinsatz angeordnet ist. Dieser zusätzliche Behälter kann mit dem Flüssigkeitsbehälter des Haushaltsgeräts verbunden werden. Hieraus ergibt sich die Möglichkeit, den Flüssigkeitsbehälter als abnehmbares Element auszubilden, um das Befüllen des Haushaltsgerätes zu erleichtern.In a further preferred embodiment is an additional one measuring Cup provided in which the measuring insert is arranged. This additional Container can with the liquid container of the household appliance get connected. This results in the possibility of the liquid container being removable Train element to fill the household appliance to facilitate.
