Description
Die Erfindung betrifft eine Manschette nach dem Oberbegriff des Patentanspruchs 1 sowie ein Wäschebehandlungsgerät nach dem Oberbegriff des Patentanspruchs 8. Dabei ist im Rahmen der vorliegenden Erfindung unter dem Betriff Wäschebehandlungsgerät sowohl eine klassische Waschmaschine als auch ein sog. Waschtrockner zu verstehen, der die Funktionen einer Waschmaschine und eines Wäschetrockners vereint.The invention relates to a sleeve according to the preamble of
Aus der
Eine Manschette und ein Wäschebehandlungsgerät der eingangs genannten Art gehen auch aus der
Diese bekannten Manschetten sind darauf gerichtet, durch Beschickungsfehler unvollständig in die Wäschetrommel eingebrachte Wäschestücke und/oder die Manschette selbst vor Beschädigungen zu schützen, wenn fehleingelegte Wäschestücke bei anlaufender Wäschetrommel verdrillen und unter der Dichtlippe weggerissen werden. Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, insbesondere bei sog. Frontlader-Wäschebehandlungsmaschinen eine zuverlässige Türöffnungsfunktion zu realisieren. Dabei soll die Rückhaltkraft, die von der an der Beschickungstür anliegenden Dichtlippe ausgeübt wird, reproduzierbar und möglichst gering sein.These known cuffs are designed to protect garments that are incompletely inserted into the laundry drum due to loading errors, and / or to protect the cuff itself from damage when incorrectly inserted items of laundry are twisted when the laundry drum starts up and are torn away below the sealing lip. In contrast, the object of the present invention is to realize a reliable door opening function, in particular in so-called front loader laundry treatment machines. In this case, the restraining force, which is exerted by the voltage applied to the loading door sealing lip, should be reproducible and minimized.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß hinsichtlich einer Manschette mit einer Manschette mit den Merkmalen des Patentanspruchs 1 und hinsichtlich eines Wäschebehandlungsgeräts mit einem Wäschebehandlungsgerät mit den Merkmalen des Patentanspruchs 8.The solution of this object succeeds according to the invention with respect to a sleeve with a sleeve having the features of
Demgemäß ist bei einer Manschette bzw. bei einem Wäschebehandlungsgerät der eingangs genannten Art erfindungsgemäß vorgesehen, dass die Anlageseite der Manschette eine Oberflächenstruktur aufweist, die zumindest eine in Umfangsrichtung umlaufende Erhebung umfasst.Accordingly, it is provided according to the invention in a cuff or in a laundry treatment appliance of the type mentioned at the outset that the contact side of the cuff has a surface structure which comprises at least one circumferential survey in the circumferential direction.
Durch die Oberflächenstruktur der Dichtlippe, die beim Schließen der Beschickungstür in Kontakt mit dieser gelangt, wird die auf die Beschickungstür wirkende Rückhaltekraft der Dichtlippe bei weiterhin gewährleisteter Dichtfunktion signifikant verringert. Die Dichtlippe gelangt nämlich nur an separierten und mithin klar definierten Kontaktzonen in Körperkontakt mit der Beschickungstür. Insbesondere, wenn die Beschickungstür einen aus Fensterglas bestehenden, sich nach innen erstreckenden Türkörper umfasst (ein sogenanntes Bullauge), der in Kontakt mit der Dichtlippe gelangt, kann die Rückhaltekraft ohne Erhöhung des Fertigungsaufwandes der Manschette präzise und reproduzierbar eingestellt werden. Dies wird durch die in geschlossenem Zustand der Beschickungstür in axialer Richtung (d.h. im Wesentlichen in Richtung des Beschickungskanals) bestehenden Bereiche eines Körperkontakts (durch die umlaufende Erhebung), d.h. fehlendem Körperkontakt der Anlageseite der Manschette, realisiert. Der sonst übliche flächige Kontaktbereich der Anlageseite wird durch die Erhebung reduziert und gegebenenfalls auf einen Körperkontakt der Erhebung begrenzt.Due to the surface structure of the sealing lip, which comes into contact with it when closing the loading door, the retaining force of the sealing lip acting on the loading door is significantly reduced while the sealing function is still ensured. Namely, the sealing lip only comes into contact with the charging door at separated and thus clearly defined contact zones. In particular, when the loading door comprises an inwardly extending door body made of window glass (a so-called porthole) which comes into contact with the sealing lip, the restraining force can be set precisely and reproducibly without increasing the manufacturing cost of the sleeve. This is determined by the areas of body contact (through the circumferential bump) in the axial direction (i.e., substantially in the direction of the feed channel) when the feed door is closed. lack of body contact the plant side of the cuff, realized. The usual area contact area of the plant side is reduced by the survey and possibly limited to a body contact of the survey.
Besonders bevorzugt ist vorgesehen, dass die Anlageseite der Manschette eine Oberflächenstruktur aufweist, zwei in Umfangsrichtung umlaufende Erhebungen umfasst, die in radialer Richtung durch mindestens eine Vertiefung beabstandet sind. Hierdurch dann vorteilhaft die Dichtfunktion, insbesondere durch eine Labyrinthbildung, sichergestellt werden, wobei dennoch ein flächiger Körperkontakt der Anlageseite der Manschette vermieden werden kann. Dabei müssen die Erhebungen nicht zwingend vollständig umlaufend (d.h. als geschlossene Ringform) ausgebildet sein, solange durch geeignete Maßnahmen - wie z.B. durch in Umfangsrichtung parallel versetzte Erhebungen oder wellen- oder mäanderförmig ausgestaltete Erhebungen - eine ausreichende Dichtfunktion in axialer Richtung sichergestellt ist. Bevorzugt ist zumindest eine bzw. sind mehrere oder alle Erhebungen in geschlossener Ringform gestaltet.It is particularly preferably provided that the contact side of the sleeve has a surface structure, comprising two circumferentially circumferential elevations, which are spaced in the radial direction by at least one recess. In this way, advantageously, the sealing function, in particular by a labyrinth formation, be ensured, yet a flat body contact of the plant side of Cuff can be avoided. In this case, the elevations do not necessarily have to be formed completely circumferentially (ie as a closed ring shape), as long as adequate measures are taken to ensure a sufficient sealing function in the axial direction by means of suitable measures, for example by elevations formed in parallel in the circumferential direction or by waves or meandering elevations. Preferably, at least one or more or all elevations are designed in a closed ring shape.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung, den Unteransprüchen und der Figurenbeschreibung, wobei einzelne Merkmale in Kombination oder einzeln angewendet werden können.Advantageous embodiments of the invention will become apparent from the following description, the dependent claims and the description of the figures, wherein individual features can be used in combination or individually.
Hinsichtlich der Formgebung der Erhebungen bzw. Vertiefungen der Oberflächenstruktur der Anlageseite ist nach einer bevorzugten Fortbildung der Erfindung vorgesehen, dass zumindest eine Erhebung im Profilquerschnitt eine Dreiecksform aufweist, wobei sich die Dreiecksform mit einer Spitze von der Anlageseite weg erstreckt.With regard to the shaping of the elevations or depressions of the surface structure of the plant side is provided according to a preferred development of the invention that at least one elevation in the profile cross-section has a triangular shape, wherein the triangular shape extends with a tip of the plant side away.
Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass zumindest eine Erhebung im Profilquerschnitt eine Rechteckform aufweist.A preferred development of the invention provides that at least one elevation in the profile cross-section has a rectangular shape.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass zumindest eine Erhebung im Profilquerschnitt eine Parabelform aufweist, deren Scheitelpunkt sich von der Anlageseite weg erstreckt.A preferred embodiment of the invention provides that at least one elevation in the profile cross-section has a parabolic shape whose apex extends away from the contact side.
Weiter bevorzugt ist eine Ausgestaltung der Erfindung, nach der zumindest eine Erhebung im Profilquerschnitt ein Haihautprofil aufweist.Further preferred is an embodiment of the invention, according to which at least one elevation in the profile cross section has a sharkskirt profile.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass eine Erhebung im Profilquerschnitt eine Sinusform aufweist, deren oberer Scheitelpunkt sich von der Anlageseite weg erstreckt.A further preferred embodiment of the invention provides that a survey in the profile cross section has a sinusoidal shape whose upper vertex extends away from the plant side.
Bei den verschiedenen bevorzugten Profilquerschnitte ist die Anlagefläche gegenüber einer unstrukturierten Oberfläche der Manschette deutlich reduziert, wobei durch Auswahl eines der vorgeschlagenen Profilquerschnittes und durch den geometrischen Abmessungen des Profilquerschnittes die für eine Dichtwirkung erforderliche Kontaktzone und die Rückhaltekraft vorteilhaft genau eingestellt werden kann. Es hat sich gezeigt, dass ein sinunsförmiger Profilquerschnitt ein besonders sanftes Schließen der Beschickungstür ermöglicht. D.h. Die während des Schließens der Beschickungstür aufzuwendende Kraft bzw. deren Änderung über den Schließweg ist gegenüber den anderen Ausführungsformen oder einer Ausführungsform ohne eine erfindungsgemäße Oberflächenstruktur reduziert. Hierbei wird nur der Kraftanteil betrachtet, der durch die Verformung der Anlageseite der Manschette in der Kontaktzone bewirkt wird.In the case of the various preferred profile cross-sections, the contact surface is significantly reduced compared to an unstructured surface of the sleeve, whereby the contact zone and the restraining force required for a sealing effect can advantageously be set precisely by selecting one of the proposed profile cross-section and by the geometric dimensions of the profile cross-section. It has been found that a sinusoidal profile cross-section is a particularly gentle closing of the Loading door allows. That is, the force to be expended during the closing of the loading door or its change via the closing path is reduced compared to the other embodiments or an embodiment without a surface structure according to the invention. Here, only the force component is considered, which is caused by the deformation of the plant side of the sleeve in the contact zone.
Es können auch verschieden profilierte oder ausgestaltete Erhebungen miteinander kombiniert werden, ohne den Gedanken der Erfindung zu verlassen.It is also different profiled or configured surveys combined with each other, without departing from the spirit of the invention.
