Description

TECHNISCHES GEBIET DER ERFINDUNGTECHNICAL FIELD OF THE INVENTION

Das technische Gebiet der Erfindung betrifft Trommeln von Waschautomaten, die auf der Oberfläche Öffnungen in zylinderartiger Form aufweisen, die sich mit Hilfe eines elektrischen Motors um die longitudinale Achse der Trommel drehen.The technical field of the invention relates to drums of washing machines, the on the surface have openings in a cylindrical shape, which help with of an electric motor around the longitudinal axis of the drum.

VORLÄUFER DER ERFINDUNGPREVENT OF THE INVENTION

Die Waschmaschinentrommeln bestehen im Allgemeinen aus einem zylinderartigen Korpus, der an den Laugenbehälter mit seiner Achse in horizontaler Position montiert wird, einem zylinderartigen Korpus, der ein geschlossenes Rückwandelement desselben und ein offenes Wandelement als vordere Einfüllöffnung für die Zuladung der Bekleidung in dessen Innenbereich aufweist.The washing machine drums generally consist of one cylindrical body, attached to the tub with its axis in horizontal position is mounted, a cylinder-like body, the one closed rear wall element thereof and an open wall element as Front filling opening for loading the clothing into its interior having.

Es gibt auch Trommeln mit größerer Füllmenge, wobei in diesem Fall beide Wandelemente geschlossen sind, falls in der Seitenwand eine zu diesem Zweck angebrachte Öffnung vorliegt.There are also drums with a larger capacity, in which case both Wall elements are closed, if in the side wall one for this purpose attached opening is present.

In jedem beliebigen Fall sind die Trommeln der Waschmaschinen mit zahlreichen Öffnungen versehen, die auf deren seitlichen und runden Oberfläche so angebracht sind, daß die Anzahl der Öffnungen einen bemerkenswerten breiten Durchmesser aufweist, um ein optimales Waschergebnis zu erlangen. Außerdem ist die Anzahl der Öffnungen begrenzt, um der Seitenwand der Trommel nicht zu schaden, da gegenwärtig die Tendenz besteht, die Geschwindigkeiten des Schleudervorganges zu erhöhen und für den Fall, daß die Trommel als Folge einer erhöhten Öffnungsanzahl und eines großen Durchmessers derselben beeinträchtigt wäre, kann es zu einem Reißen und sogar zur Beschädigung der Kleidung bei deren Reibung auf den Rändern der besagten Öffnungen kommen, weil deren gestanzter Ausschnitt normalerweise Mängel aufweist und demzufolge Ränder, die sowohl durch Reibung wie auch durch Hängenbleiben die Kleidung angreifen. In any case, the drums of the washing machines are numerous Openings provided on the lateral and round surface so attached are that the number of openings a remarkable wide Diameter, in order to obtain an optimal washing result. Furthermore the number of openings is limited to the side wall of the drum not too harm, because at present the tendency exists, the speeds of the To increase the spin process and in the event that the drum as a result an increased number of openings and a large diameter thereof it could cause tearing and even damage to the Clothes rubbing on the edges of said openings, because their punched cutout usually has defects and consequently, edges that are both frictional and trapped attack the clothes.

Dessen ungeachtet sind Trommeln bei Waschmaschinen mit einer verminderten Anzahl an Öffnungen und einem kleinen Durchmesser bekannt, wodurch de Oberfläche der Trommelwand weniger angreifend wirkt. Außerdem erlaubt die Verringerung des Durchmessers der Öffnungen kein Durchtreten von Teilstücken der Bekleidung, was dagegen bei großen Durchmessern der Fall ist.Nevertheless, drums are on washing machines with a reduced Number of openings and a small diameter known, whereby de Surface of the drum wall acts less attacking. In addition, the allowed Reducing the diameter of the openings no passage of sections clothing, which is the case for large diameters.

BESCHREIBUNG DER ERFINDUNGDESCRIPTION OF THE INVENTION

Die vorliegende Erfindung betrifft, wie im Titel dieser erläuternden Beschreibung zum Ausdruck gebracht wird, die Trommel einer Waschmaschine, die die Besonderheit aufweist über ein Auflegeelement auf dem Berührungsbereich der Kleidung zu verfügen, damit die Aggressivität, der normalerweise die Kleidungsstücke durch die entsprechenden Ränder der Öffnungen ausgesetzt sind und mit denen die Seitenfläche der Trommeln der Waschmaschinen versehen sind, vermieden wird.The present invention relates, as in the title of this illustrative description is expressed, the drum of a washing machine, which the Feature has a laying element on the contact area of the To dispose of clothing, so that the aggressiveness, which is usually the Garments exposed through the corresponding edges of the openings are and with which the side surface of the drums of washing machines are provided is avoided.

Aufgabe der Erfindung ist zu vermeiden, daß die Kleidungsstücke, die in die Trommel einer Waschmaschine eingegeben werden, während ihres Waschvorganges beeinträchtigt werden sowie zu verhindern, daß die Trommel selbst beim Waschen aggressiver Gegenstände, wie Schuhe, Schaden erleidet.The object of the invention is to avoid that the garments in the Drum of a washing machine to be entered during her Washing process to be impaired as well as to prevent the drum even when washing aggressive items, such as shoes, suffers damage.

Die erfindungsgemäße Trommel der Waschmaschine weist die Besonderheit auf, daß die in Form eines zylinderartigen Korpus mit einer Rückwand und einer Vorderwand ausgebildete Trommel, deren besagter zylinderartige Korpus auf seiner Seitenfläche Öffnungen zum Passieren des im Laugenbehälter enthaltenen Wassers zum Innenbereich der Trommel aufweist, über ein Auflegeelement verfügt, das auf die Seitenfläche der Trommel, wo deren Öffnungen vorliegen, und zumindest auf einem Bereich oder auf keinem der Rückwand und einem Bereich oder keinem der Vorderwand, angeordnet ist, das die aggressiven Effekte auf die Kleidungsstücke und auf die Waschtrommel minimiert. Außerdem variiert die Aufnahme des Auflegeelementes die Vibrationsweise und -frequenz der Trommel, wodurch die Geräusche der Waschmaschine reduziert werden. The drum of the washing machine according to the invention has the peculiarity that in the form of a cylinder-like body with a rear wall and a Front wall formed drum, said cylinder-like body on its side surface openings for passing in the tub contained water to the interior of the drum, over a Laying element features on the side surface of the drum where its Openings are present, and at least on an area or on none of Rear wall and an area or none of the front wall, which is arranged the aggressive effects on the garments and on the washing drum minimized. In addition, the inclusion of the laying element varies the Vibration mode and frequency of the drum, which reduces the noise of the Washing machine to be reduced.

Es ist unbedeutend, ob die Waschmaschine ein Frontlader oder für höhere Zuladungen ausgelegt ist, da das Auflegeelement für alle Waschmaschinenarten angepaßt werden kann.It is insignificant whether the washing machine is a front loader or for higher Payloads is designed as the lay-on element for all washing machine types can be adapted.

Bei einer Ausführungsvariante kann das Auflegeelement im Innenbereich der Trommel angeordnet sein und aus einer Folie aus Kunststoffmaterial mit Löchern geringen Durchmessers bestehen, die sehr zahlreich sind, um das Durchfließen des Wassers in das Trommelinnere zu begünstigen, jedoch einen sehr geringen Durchmesser aufweisen, damit die Kleidungsstücke beim Schleudern mit hohen Geschwindigkeiten keinen Schaden durch das Hindurchtreten durch diese erleidet. Auf diese Weise benötigt die Trommel aus nichtrostendem Stahl keine spiegelähnliche Verarbeitung, die zwar attraktiver, aber für den Kunden nicht mehr sichtbar ist. Das immer dann, wenn das Auflegeelement oder Innenfolie nicht abnehmbar ist.In one embodiment, the laying element in the interior of the Drum be arranged and made of a film of plastic material with holes small diameter, which are very numerous to the flow of the water in the interior of the drum to favor, but a very small Diameter, so that the garments when spinning with high Speeds no damage by passing through this suffers. In this way, the stainless steel drum needs no Mirror-like workmanship, while attractive, but not for the customer is more visible. That always when the laying element or inner foil is not removable.

Die besagte Folie kann ebenfalls flach sein, eine Aufrauhung oder unterschiedliche geometrische Formen aufweisen. Die geometrischen Formen sind sehr wichtig, da auf einer flachen Rotationstrommel eine Auflegefolie eingegeben werden kann, die aus Kunststoff und einem einzigen Stück besteht, die Wasserbrechelemente integriert, die die Trommeln in den üblichen Waschmaschinenausführungen gewöhnlich aus Metall aufweisen.The said film may also be flat, a roughening or have different geometric shapes. The geometric shapes are very important, because on a flat rotary drum a laying foil can be entered, which consists of plastic and a single piece, The water breaker integrated the drums into the usual Washing machine versions usually made of metal.

Die geometrischen Formen geringerer Größe mit Wölbungen dienen einer schonenderen Behandlung der Kleidung, weil sie die Kleidungsstücke noch mehr von der Metalltrommel beabstanden und vermeiden, daß sie an ihnen hängenbleiben. Sie reduzieren ebenfalls in beträchtlicher Weise das Geräusch des Waschvorganges, da es zu keiner Reibung zwischen Metallteilen, die die Kleidungsstücke aufweisen können, kommt, aber vor allem wenn Gegenstände größeren Gewichtes gewaschen werden, die mit stärkerer Kraft gegen die Trommel schlagen und abgefedert werden.The geometric shapes of lesser size with vaults serve one Gentle treatment of clothing, because they even more clothing spaced from the metal drum and avoid that they get stuck on them. They also significantly reduce the noise of the Washing process, as there is no friction between metal parts, the Clothes can come, but especially if objects to be washed with greater force against the greater weight Beat the drum and cushioned.

Ein weiterer Effekt der Wölbungen oder erhabenen Ausbildungen besteht darin, daß sie als Speicher von Wasser dienen, das sie während des Waschvorganges freigeben sowie einen Duscheffekt auf den Kleidungsstücken, genau in dem Moment, in dem die Trommel die Rotation beendet hat, bewirken.Another effect of the bulges or sublime formations is that they serve as a reservoir of water that they use during the washing process release as well as a showering effect on the garments, exactly in that Moment when the drum has finished the rotation effect.

Diese erhabenen Ausbildungen können, wie vorhergehend schon erwähnt, auch in ausgeprägteren Formen vorliegen, in der Art von Wasserbrechelementen, wobei die Herstellung dieser unverzichtbaren Elemente auf Metalltrommeln vermieden wird, wodurch es bei der Herstellung zu einer Einsparung kommt. Da sie in einer Folie aus einem oder mehreren Stücken gefertigt wird, können alle erhabenen Ausbildungsarten zum Einsatz kommen, die die Bewegung der Kleidungstücke in der Trommel sowie den Waschvorgang begünstigen.These sublime educations can, as previously mentioned, also present in more pronounced forms, in the nature of water breakage elements, the production of these indispensable elements on metal drums is avoided, whereby it comes to a saving in the production. There It can be made in one piece from one or more pieces sublime forms of training are used, the movement of the Clothes items in the drum and the washing process favor.

Diese Folie kann im Prinzip aus Kunststoff oder auch Metall, in der Art einer dünnen Folie oder auch eines Maschen- oder Metallnetzes mit einem ziemlich geschlossenen Maschengeflecht sein, wobei sie einen noch größeren Eindruck an Sauberkeit verleiht.This foil can in principle be made of plastic or metal, in the manner of a thin film or even a mesh or metal net with a pretty closed mesh, giving an even bigger impression gives to cleanliness.

Diese Folie kann sich während des Waschvorganges aufgrund der eigenen Zentrifugalkraft fixieren, wenn jedoch nötig, kann sie mit abnehmbaren oder nicht abnehmbaren Clips an den Öffnungen der Trommel oder mittels Schrauben oder Nieten, falls eine ortsfeste Form bevorzugt wird, angebracht werden.This film may be damaged during the washing process due to its own Fix centrifugal force, if necessary, it can be removable or not removable clips on the openings of the drum or by means of screws or Rivets, if a fixed shape is preferred, be attached.

Die abnehmbare Version stellt einen Vorteil dar, da sie in Waschvorgängen eingesetzt werden kann, wo sie tatsächlich nötig ist, beispielsweise beim Waschen von schweren Gegenständen wie Schuhwerk, oder wenn große Schleudergeschwindigkeiten nötig sind. Und es besteht dann auch die Möglichkeit, das Auflegeelement in schon vorliegenden Trommeln anzuordnen, da die Größen der Trommeln gewöhnlich Standardausführungen entsprechen. Und im Fall, daß die Folie beschädigt werden würde, wäre sie leicht austauschbar.The removable version is an advantage as it is used in washing can be used, where it is actually necessary, for example Washing heavy items such as footwear, or when big Spin speeds are needed. And then there is the Possibility to arrange the laying element in already existing drums, since the sizes of the drums usually correspond to standard versions. And in case the foil would be damaged, it would be light interchangeable.

Bei einer anderen Variante der Ausführung kann das Auflegeelement aus einem Kunststoffband bestehen, das auf der Außenfläche befestigt wird, wobei ein Teil des Kunststoffes durch die Öffnungen der Trommel hindurchtritt und in deren Innenbereich in Warzenform hineinreicht, um eine Überdeckung und Schutz der Ränder der besagten Öffnungen festzulegen und verhindert, daß die Kleidung beschädigt wird.In another variant of the embodiment, the laying element of a Plastic band that is attached to the outer surface, with a part the plastic passes through the openings of the drum and in the Inside area in wart form extends to cover and protect the Determine margins of said openings and prevents the clothing is damaged.

Das genannte Band kann die Außenfläche der Trommel total oder teilweise überdecken und kann an diese durch geeignete Mittel befestigt werden, solchen wie Clips, Schrauben, usw., obwohl zu dessen Befestigung auch die Fixierung genügt, die die Warzen des Kunststoffbandes, die in den Öffnungen hindurchtreten, erfahren.Said band may be the outer surface of the drum totally or partially cover and can be attached to them by suitable means, such like clips, screws, etc., although to fix it also the fixation It suffices that the warts of the plastic band, in the openings pass through, experienced.

Und zur Differenzierung oder dem Verleihen eines attraktiveren Charakters, beispielsweise, daß die Kleidung in der Trommel ins Auge springt, weist das Auflegeelement eine andere oder die gleiche Farbe des Materials der Trommel selbst auf, wodurch es der Waschmaschinentrommel eine neue und attraktive Ästhetik verleiht.And to differentiate or lend a more attractive character, For example, the clothes in the drum jumps in the eye, that indicates Laying on a different or the same color of the material of the drum itself on, making it a new and attractive to the washing machine drum Gives aesthetics.

Für den Fall, daß sie aus Kunststoffmaterial besteht, kann die genannte Folie mittels Einspritzung oder eines anderen Verfahrens hergestellt werden, das die Erzeugung von Folien verschiedener Größen, Formen, Farben, usw., erlaubt, wobei sie in jedem Fall mit Öffnungen versehen sein muss, um den Durchfluss des Waschwassers zu erlauben.In the event that it consists of plastic material, the said film be made by injection or other method that the Production of foils of various sizes, shapes, colors, etc., allowed, in any case, it must be provided with openings to the flow to allow the washing water.

Für den Fall, daß die Folie metallartig ist, kann sie aus sehr feinen Drähten, in einer dem Zweck dienlichen Form und Größen hergestellt sein.In the event that the film is metal-like, it can be made of very fine wires, in be made of a useful shape and sizes.

Und schließlich, durch das zur Verfügung stellen einer Trommel, die vielseitiger zu verwenden ist, wird eine enorme Verbesserung in der Effizienz des Wasch - und Schleudervorgangs erreicht.And finally, by providing a drum that is more versatile to use is a huge improvement in the efficiency of the washing and spin cycle achieved.

Mit all diesen Charakteristiken können Auflegeelemente in geometrischen und funktionellen Variationen, je nach Modell und Leistung, eingesetzt werden.With all these characteristics, lay-on elements in geometric and functional variations, depending on the model and performance, are used.
