Abstract
Description
Die Erfindung bezieht sich auf eine Fronttüre für die Beschickung einer Waschmaschine, bei welcher ein zum Inneren der Waschtrommel hin versenktes Bullaugenglas in einem Halterahmen vorgesehen ist.The invention relates to a front door for loading a washing machine, in which a porthole glass sunk towards the inside of the washing drum is provided in a holding frame.
Da bei herkömmlichen Waschmaschinen das Bullaugenglas mit dem Waschwasser bzw. der Waschlauge direkt in Verbindung steht, weil an dem Bullaugenglas ein Teil der Abdichtung gegenüber dem Inneren des Laugenbehälters erfolgt, nimmt das Bullaugenglas die Temperatur des Waschwassers bzw. der Waschlauge an. Bei Kochwäsche kann das bis zu 95° betragen. Dadurch kann es bei Berühren oder Anfassen des Bullaugenglases zu Verbrennungen an den Händen kommen. Es dürfen allerdings laut österreichischer Maschinenschutzverordnung Maschinenteile, die eine Oberflächentemperatur von mehr als 60° erreichen, nicht an der Außenseite des Gerätes angebracht sein.Since, in conventional washing machines, the porthole glass is directly connected to the wash water or the wash liquor, because part of the seal against the interior of the suds container takes place on the porthole glass, the porthole glass assumes the temperature of the wash water or the wash liquor. This can be up to 95 ° for hot laundry. This can cause burns to your hands when you touch or touch the porthole glass. However, according to the Austrian Machine Protection Ordinance, machine parts that reach a surface temperature of more than 60 ° must not be attached to the outside of the device.
Es wurde daher bereits eine Ausbildung geschaffen, bei welcher das Bullaugenglas an der Außenseite durch eine durchgehende Tür abgedeckt ist. Eine solche Ausbildung hat den Nachteil, daß einerseits die die Waschmaschine bedienende Person den Waschvorgang nicht mehr visuell überwachen kann, und daß andererseits eine erhöhte Bautiefe der Waschmaschine gegeben ist, wodurch dann die Waschmaschine nicht mehr einbaufähig ist.Training has therefore already been created in which the porthole glass is covered on the outside by a continuous door. Such a design has the disadvantage that, on the one hand, the person operating the washing machine can no longer visually monitor the washing process, and, on the other hand, there is an increased overall depth of the washing machine, as a result of which the washing machine can then no longer be installed.
Der Erfindung liegt die Aufgabe zugrunde, eine Fronttüre der eingangs genannten Art zu schaffen, bei welcher einerseits eine übermäßige Erwärmung von an der Außenseite der Waschmaschine befindlichen Teilen verhindert ist, und wobei andererseits der Waschvorgang visuell überwacht werden kann.The invention has for its object to provide a front door of the type mentioned, in which on the one hand excessive heating of parts located on the outside of the washing machine is prevented, and on the other hand the washing process can be monitored visually.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das versenkte Bullaugenglas vorzugsweise gegenüber dem Halterahmen thermisch isoliert ist, und daß außerhalb des versenkten Bullaugenglases im Halterahmen eine weitere, wenigstens bereichsweise, durchsichtige Abdeckblende angeordnet ist. Dies ermöglicht einerseits das visuelle Beobachten des Waschvorganges, beispielsweise um feststellen zu können, ob ein Wäschestück ausgefärbt hat, und gibt andererseits die Sicherheit, daß Verbrennungen durch unbedachtes Berühren des Bullaugenglases vermieden sind. Weiters bedeutet die erfindungsgemäße Ausbildung keine Veränderung der Außenausbildung der Waschmaschine, so daß eine Einbaufähigkeit od. dgl. nicht beeinträchtigt wird. Auch ist dadurch eine etwaige Nachrüstung bereits bestehender Waschmaschinen ermöglicht. Schließlich kann bei Verwendung der thermischen Isolierung des Halterahmens gegenüber dem Bullaugenglas der Halterahmen aus gut wärmeleitendem Material, wie z.B. Metall, gefertigt sein, wodurch eine höhere Stabilität der Fronttüre erzielt wird.According to the invention, this object is achieved in that the sunken porthole glass is preferably thermally insulated from the holding frame, and in that, outside the sunken porthole glass in the holding frame, a further, at least in some areas, transparent Cover panel is arranged. On the one hand, this enables the washing process to be observed visually, for example in order to be able to determine whether a piece of laundry has colored, and on the other hand provides the certainty that burns are avoided by carelessly touching the porthole glass. Furthermore, the design according to the invention means no change in the external design of the washing machine, so that an installation capability or the like is not impaired. This also enables retrofitting of existing washing machines. Finally, when using the thermal insulation of the holding frame with respect to the porthole glass, the holding frame can be made from a material which is a good heat conductor, such as metal, for example, whereby a higher stability of the front door is achieved.
Vorteilhafterweise kann das Bullaugenglas gegenüber dem Halterahmen thermisch isoliert an letzterem befestigt sein, wobei der Halterahmen und die Abdeckblende hinterlüftet sind. Dies ergibt den Vorteil, daß ein durch die Wärmeleitfähigkeit des Bullaugenglases hervorgerufenes Aufheizen des Halterahmens vermieden ist. Zudem wird durch die Hinterlüftung auch noch erreicht, daß ein Beschlagen des Glases und damit ein Undurchsichtigmachen desselben verhindert ist. Es kann jedoch die Abdeckblende mit dem Bullaugenglas auch zu einer Isolierglaseinheit zusammengefaßt sein, wobei vorzugsweise die Isolierglaseinheit am Halterahmen wärmeisoliert befestigt ist. Dadurch werden die gleichen Effekte erzielt, wie sie durch eine hinterlüftete Abdeckblende erreicht werden.Advantageously, the porthole glass can be attached to the holding frame in a thermally insulated manner, the holding frame and the cover panel being ventilated. This has the advantage that heating of the holding frame caused by the thermal conductivity of the porthole glass is avoided. In addition, the rear ventilation also prevents fogging of the glass and thus obscuring it. However, the cover panel with the porthole glass can also be combined to form an insulating glass unit, the insulating glass unit preferably being attached to the holding frame in a heat-insulated manner. This achieves the same effects as can be achieved with a rear-ventilated cover panel.
In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt.
- Fig. 1 zeigt einen Horizontalschnitt durch das erste Ausführungsbeispiel,
- Fig 2 einen Schnitt durch ein zweites Ausführungsbeispiel.
- 1 shows a horizontal section through the first embodiment,
- Fig. 2 shows a section through a second embodiment.
Bei beiden Ausführungsbeispielen sind mit 1 der Halterahmen, mit 2 das Bullaugenglas und mit 3 die Abdeckblende bezeichnet.In both exemplary embodiments, 1 denotes the holding frame, 2 the porthole glass and 3 the cover panel.
Wie aus Fig. 1 ersichtlich, ist das Bullaugenglas 2 von der Abdeckblende 3 durch einen Spalt 4 distanziert, welcher durch nicht dargestellte, herkömmliche Distanzorgane eingehalten ist. Der Spalt 4 mündet in einen Ringraum 5 des Halterahmens ein, welcher über über den Umfang des Halterahmens verteilte Öffnungen 6 mit der Umgebungsluft in Verbindung steht. Durch die Öffnungen 6 kann Frischluft in den Ringraum 5 eintreten, von welchem aus die Frischluft über den Spalt 4 in den Innenraum zwischen dem Bullaugenglas und der Abdeckblende eintreten kann. An der gegenüberliegenden Seite kann die warme Luft über den Spalt 4 und die entsprechenden Öffnungen 6 wieder austreten. Auf diese Art ist ein stetiger Luftwechsel bzw. eine stetige Luftströmung im Innenraum zwischen dem Bullaugenglas und der Abdeckblende gegeben.As can be seen from FIG. 1, the
Beim Ausführungsbeispiel gemäß Fig. 2 ist ein derartiger Luftwechsel nicht vorgesehen und auch nicht erforderlich, da aufgrund des Aufbaues in Form einer herkömmlichen Isolierverglasung der Raum zwischen dem Bullaugenglas und der Abdeckblende wenigstens zum Teil evakuiert ist, wodurch die gewünschte Isolierwirkung erzielt ist.In the exemplary embodiment according to FIG. 2, such an air change is not provided and also not necessary, since, due to the structure in the form of conventional insulating glass, the space between the porthole glass and the cover panel is at least partially evacuated, thereby achieving the desired insulating effect.
Bei beiden Ausführungsbeispielen kann in nicht dargestellter Weise die Halterung des Bullaugenglases 2 bzw. der Abdeckblende 3 innerhalb des Halterahmens 1 über Wärmeisoliermittel erfolgen, wodurch eine durch Wärmeleitung des Bullaugenglases erzielte Aufwärmung des Halterahmens vermieden ist.In both exemplary embodiments, the
Die erfindungsgemäße Türe für Waschmaschinen ist bei jeder herkömmlichen Waschmaschine einsetzbar, wobei das Bullaugenglas 2 "topfförmig" ausgebildet ist und über die Topfwandung die Abdichtung gegenüber dem Laugenbehälter erfolgt.The door according to the invention for washing machines can be used in any conventional washing machine, the
