Description
Die Erfindung bezieht sich auf ein Bedienelement zur Steuerung von elektrisch ansteuerbaren Elektrokochgeräten, das auf einer Bedienfläche des Elektrokochgeräts mittels Magnetkraft drehbar und abnehmbar halterbar ist und aus mehreren separaten, ein allseits geschlossenes Gehäuse bildenden Teilen zusammengefügt ist.The invention relates to an operating element for controlling electrically controllable electric cooking devices, which can be rotated and detachable on a control surface of the electric cooking device by means of magnetic force and is assembled from several separate parts forming a housing that is closed on all sides.
Ein derartiges Bedienelement ist offenbart in
Derartige Bedienelemente, die z. B. bei Küchenarbeiten an Kochgeräten rasch verschmutzen, können zwar von der Bedienfläche des Kochgerätes z. B. von der Glaskeramikplatte eines Kochfeldes einfach abgenommen und manuell gereinigt werden. Sie sind jedoch meist nicht geeignet für eine gründliche Reinigung in einer Spülflüssigkeit z. B. in einer Geschirrspülmaschine, da flüssigkeitsdurchlässige Leckstellen im Bereich der Fügestellen, auch eventuell an Klebestellen, nicht dauerhaft auszuschließen sind und Flüssigkeit in den Hohlraum im Inneren des Bedienelementes gelangen und dann bei Gebrauch des Bedienelementes auf die Bedienfläche auslaufen kann.Such controls that z. B. quickly soiled during kitchen work on cooking appliances, although from the control surface of the cooking appliance z. B. can be easily removed from the glass ceramic plate of a hob and cleaned manually. However, they are usually not suitable for thorough cleaning in a rinsing liquid z. B. in a dishwasher, since liquid-permeable leaks in the area of the joints, possibly also at glue points, cannot be permanently excluded and liquid can get into the cavity inside the control element and then leak onto the control surface when the control element is used.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Bedienelement der eingangs genannten Art derart weiterzubilden, dass vorgenannte Leckstellen vermieden werden und eine gründliche z. B. maschinelle Reinigung in einer Spülflüssigkeit z. B. einer Geschirrspülmaschine problemlos ermöglicht wird.The present invention is therefore based on the object of developing a control element of the type mentioned in such a way that the aforementioned leaks are avoided and a thorough z. B. machine cleaning in a rinsing liquid z. B. a dishwasher is made possible without any problems.
Diese Aufgabe wird bei dem Bedienelement der eingangs genannten Art dadurch gelöst, dass zwischen den Teilen an den Fügestellen flüssigkeitsdichte Dichtungselemente vorhanden sind. Unter einem solchen Dichtungselement ist nicht ausschließlich, aber vorzugsweise ein separat montierbares Element wie z. B. ein handelsüblicher Dichtungsring (O-Ring) zu verstehen. Durch diese zusätzlich zur losen mechanischen Verbindung der Teile des Bedienelementes vorgesehene Maßnahme bzw. Ausgestaltung wird eine vollständige Dichtheit gegenüber jedweden Flüssigkeiten erreicht, so dass sogar eine Vollreinigung in mit hohem Flüssigkeitsdruck arbeitenden Geschirrspülmaschinen problemlos möglich ist.In the case of the operating element of the type mentioned at the outset, this object is achieved in that liquid-tight sealing elements are present between the parts at the joints. Such a sealing element is not exclusively, but preferably a separately mountable element such. B. to understand a commercially available sealing ring (O-ring). This measure or configuration, which is provided in addition to the loose mechanical connection of the parts of the operating element, achieves complete impermeability to any liquids, so that even complete cleaning in dishwashers operating at high liquid pressure is possible without any problems.
Gemäß der Erfindung ist vorgesehen, dass die äußeren Teile des Bedienelementes gebildet sind durch eine Laufplatte, deren Lauffläche auf der Bedienfläche lagerbar ist, und durch einen hohlen Griffteil, in dem die Laufplatte mittels Rastverbindung befestigt ist, wobei in einem Hohlraum des Griffteils ein Magnet sowie ein mit sternförmigen Armen ausgestattetes Element aus ferromagnetischem Material angeordnet sind, und dass zwischen den genannten Teilen, nämlich an einer ringförmigen Fügestelle zwischen dem Griffteil und der Laufplatte, das aus elastischem Kunststoff bestehende ringförmige Dichtungselement angeordnet ist. Bei dieser Anordnung ist die Fertigmontage des Bedienelementes in kontinuierlich aufeinander folgenden Arbeitsschritten problemlos möglich.According to the invention it is provided that the outer parts of the control element are formed by a running plate, the running surface of which can be stored on the operating surface, and by a hollow handle part in which the running plate is fastened by means of a latching connection, a magnet and a cavity in the handle part an element made of ferromagnetic material equipped with star-shaped arms are arranged, and that the ring-shaped sealing element made of elastic plastic is arranged between said parts, namely at an annular joint between the handle part and the running plate. With this arrangement, the final assembly of the control element is possible without any problems in continuously successive work steps.
Bei einer leicht geänderten Ausführungsform des Bedienelementes ist vorgesehen, dass das Griffteil eine als Einzelteil über ein vorzugsweise ringförmiges Dichtungselement befestigte Griffkappe aufweist.In a slightly modified embodiment of the operating element, it is provided that the handle part has a handle cap fastened as an individual part via a preferably ring-shaped sealing element.
Eine bestmögliche Dichtheit der miteinander dichtend zu verbindenden Teile des Bedienelementes wird dadurch erreicht, dass die Fügestelle der zusammengefügten Teile an dem einen Teil eine winkelige Stützflächen aufweisende Stützschulter und an dem anderen Teil eine zu den genannten Stützflächen eine resultierende Stützkraft ausübende Stützfläche für das Dichtungselement aufweist.The best possible tightness of the parts of the control element that are to be connected to one another in a sealing manner is achieved in that the joint of the joined parts has an angular supporting surface on one part and a supporting surface for the sealing element that exerts a supporting force on the other part.
