Abstract

In a tumble dryer of the top-loading type, with a plastic tub and with a washing and spinning drum (3) arranged therein, at least one tunnel-shaped indentation (5) is fashioned in a superstructure (2) designed as a filling shaft, with the result that it becomes substantially easier to position the drum manually into the loading and unloading position. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Trommelwaschmaschine in mantelbeschickbarer Bauweise, insbesondere für die Anwendung im Haushalt, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a drum-type washing machine with a coat-loading design, in particular for use in the household, according to the preamble of claim 1.

Es sind bereits Trommelwaschmaschinen dieser Bauart bekannt, bei denen eine Positionierung der Trommel zum Zwecke des Be- oder Entladens mit Waschgut, d.h. ein Drehen der Wasch- und Schleudertrommel um die Trommelöffnung mit der Wäscheeinfüllöffnung in übereinstimmung zu bringen, nur im Bereich der Einfüllöffnung manuell erfolgen kann.
Dies trifft besonders bei Laugenbehälter aus Kunststoff zu, die aus einem topfförmigen und einem deckelförmigen Teil mit vertikaler Teilungsebene bestehen und bei denen zum Zwecke eines minimalen Wasser- und Energieverbrauches nur ein relatv geringer Spalt zwischen der Innenwand des Laugenbehälters und der Wasch- und Schleudertrommel vorhanden ist.
Die speziell am Mantel der Wasch- und Schleudertrommel vorgesehenen Griffelemente für eine manuellle Positionierung verlieren auf Grund der durch eine relativ kleine Einfüllöffnung und dem vorhandenen geringen Spalt zwischen Trommelmantel und Laugenbehälter gegebenen begrenzten Zugänglichkeit zum Trommelmantel ihre Wirkung bei der Bewegung der Wasch- und Schleudertrommel von Hand.
Außerdem lassen diese relativ kleine Einfüllöffnung und der vorhandene Spalt nur eine manuelle Drehung der Wasch- und Schleudertrommel um zirka 30 bis 50 Grad - oft mit einem hohen Kraftaufwand für die bedienende Person verbunden - zu.
Diese eingeschränkte manuelle Bedienbarkeit führt dazu, daß nach dem manuellen Drehen, bei einem Griffwechsel bzw. Nachfassen, sich die Trommel wieder in ihre ursprüngliche Schwerpunktlage zurückbewegen will, denn erst bei einem Drehwinkel von zirka 50 bis 70 Grad kommt es durch die Verlagerung des Waschgutes zu einer neuen Schwerpunktlage, die eine exakte Positionierung der Trommel ermöglicht.Drum washing machines of this type are already known, in which a positioning of the drum for the purpose of loading or unloading with laundry, ie rotating the washing and spinning drum to bring the drum opening into agreement with the laundry filling opening, is carried out manually only in the region of the filling opening can.
This is particularly true for plastic tubs made of a pot-shaped and a lid-shaped one Part exist with a vertical division level and in which there is only a relatively small gap between the inner wall of the tub and the washing and spinning drum for the purpose of minimal water and energy consumption.
The handle elements specially provided on the jacket of the washing and centrifuging drum for manual positioning lose their effect when the washing and centrifuging drum is moved by hand due to the limited accessibility to the drum jacket given by a relatively small filling opening and the small gap between the drum jacket and tub .
In addition, this relatively small filling opening and the existing gap only allow the washing and centrifuging drum to be rotated manually by approximately 30 to 50 degrees, often with great effort on the part of the operator.
This limited manual operability leads to the fact that after manual rotation, when changing handles or grasping, the drum wants to move back to its original center of gravity, because only at a rotation angle of about 50 to 70 degrees does the laundry move a new center of gravity, which enables exact positioning of the drum.

Ferner besteht bei dem manuellen Drehen der Wasch- und Schleudertrommel auf Grund des relativ geringen Spaltes zwischen Trommelmantel und Laugenbehälter, für die bedienende Person die Gefahr einer Verletzung an den Fingern.Furthermore, when the washing and centrifuging drums are turned manually, there is a risk of injury to the fingers due to the relatively small gap between the drum casing and the tub.

Weitere bekannte technische Lösungen zum automatischen Positionieren der Wasch- und Schleudertrommel mit Hilfe elektromechanischer und /oder elektronischer Steuerungseinrichtungen, z.B. über die Ansteuerung des Antriebsmotors, haben den Nachteil, daß sie einen relativ hohen technischen Aufwand erfordern, wodurch sich die Störanfälligkeit der Waschmaschine erhöhen kann.Other known technical solutions for the automatic positioning of the washing and centrifuging drum with the aid of electromechanical and / or electronic control devices, e.g. By controlling the drive motor, they have the disadvantage that they require a relatively high level of technical complexity, which can increase the susceptibility to failure of the washing machine.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, bei einer Trommelwaschmaschine gemäß dem Oberbegriff des Anspruches 1, die vorstehend genannten Nachteile für die bedienende Person beim manuellen Positionieren der Wasch- und Schleudertrommel nach Beendigung des Schleuderganges zu vermeiden.The present invention is therefore based on the object, in a drum washing machine according to the preamble of claim 1, to avoid the aforementioned disadvantages for the operator when manually positioning the washing and centrifuging drum after the end of the spin cycle.

Diese technische Aufgabe wird durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst.This technical problem is solved by the features specified in the characterizing part of claim 1.

Die Vorteile, die durch die Erfindung gegenüber den bekannten technischen Lösungen erreicht werden, bestehen darin, daß ein manuelles Bewegen der Wasch- und Schleudertrommel in die erforderliche Be- oder Entladestellung mühelos und ohne Verletzungsrisiko ermöglicht wird.
Bedingt durch die Ausbildung und Wahl der Bemessung der Wäscheeinfüllöffnung, insbesondere der tunnelförmigen Ausbuchtungen, wird ein wesentlich größeres Griffeld geschaffen und damit ein größerer Drehwinkel erreicht, wodurch gewährleistet wird, daß bei der manuellen Drehung eine neue Schwerpunktlage des Waschgutes entsteht und damit ein Zurückrollen der Wasch- und Schleudertrommel weitestgehend vermieden wird.The advantages achieved by the invention compared to the known technical solutions consist in the fact that a manual movement of the washing and spinning drum into the required loading or unloading position is made possible effortlessly and without risk of injury.
Due to the design and choice of the dimensioning of the laundry filling opening, in particular the tunnel-shaped bulges, a much larger stylus is created and thus a larger angle of rotation is achieved, which ensures that a new center of gravity of the laundry is created during manual rotation and thus rolling back of the laundry - and centrifugal drum is largely avoided.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den übrigen Unteransprüchen und aus dem nachfolgend an Hand der Zeichnung prinzipmäßig beschriebenen Ausführungsbeispiel.Advantageous refinements of the invention result from the remaining subclaims and from the exemplary embodiment described in principle below with reference to the drawing.

Dabei zeigt:

It shows:
Fig. 1
a sectional view of a drum washing machine.

Am Laugenbehälter 1 ist ein als Befüllungsschacht dienender Aufsatz 2 angeordnet.An attachment 2 serving as a filling shaft is arranged on the tub 1.

Ausgehend von diesem Aufsatz 2 sind in beide Drehrichtungen der Wasch- und Schleudertrommel 3 verlaufend je eine tunnelförmig ausgebildete Ausbuchtung 5 in den Laugenbehälter 1 eingearbeitet.
Diese wird zweckmäßigerweise im Rahmen des Spritzvorganges bei der Fertigung des Laugenbehälters 1 aus Kunststoff realisiert.
Die Bemessung dieser Ausbuchtungen 5 ist so gewählt, daß für die bedienende Person ein ausreichend großes Bedien- bzw. Griffeld für ein manuelles Drehen der Wasch- und Schleudertrommel 3 vorhanden ist, wobei das Bogenmaß 6 der Einfüllöffnung zusammen mit dem Bogenmaß 7 der tunnelförmigen Ausbuchtungen 5 größer ist als das Bogenmaß 8 zwischen zwei auf dem Trommelmantel 4 der Wasch- und Schleudertrommel 3 angeordeneten Griffelementen 9.
Dadurch ist gewährleistet, daß immer mindestens eines der Griffelemente 9 sicher erfaßt und somit die Wasch- und Schleudertrommel 3 per Hand so positioniert werden kann, daß sich die Trommeleinfüllöffnung - bestehend aus den Trommelklappen 10 und 11 - in dem Aufsatz 2 befindet und diese geöffnet werden kann.Proceeding from this attachment 2, a tunnel-shaped bulge 5 is incorporated into the tub 1 in both directions of rotation of the washing and centrifuging drums 3.
This is expediently implemented in the course of the injection molding process in the manufacture of the tub 1 from plastic.
The dimensioning of these bulges 5 is selected so that the operator has a sufficiently large control or stylus for manually rotating the washing and centrifugal drum 3, the radian 6 of the filling opening together with the radian 7 of the tunnel-shaped bulges 5 is greater than the radian 8 between two handle elements 9 arranged on the drum jacket 4 of the washing and centrifuging drum 3.
This ensures that at least one of the handle elements 9 is always securely gripped and thus the washing and centrifuging drum 3 can be positioned by hand in such a way that the drum filler opening - consisting of the drum flaps 10 and 11 - is located in the attachment 2 and opened can.
