Es ist Aufgabe der vorliegenden Erfindung, eine Wäschebehandlungsmaschine mit einer einfach aufgebauten und platzsparenden Dampferzeugungseinrichtung bereit zu stellen.It is an object of the present invention to provide a laundry treatment machine with a simply constructed and space-saving steam generating device.

Die Aufgabe wird durch eine Wäschebehandlungsmaschine mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungen ergeben sich aus den nachfolgenden abhängigen Ansprüchen.The object is achieved by a laundry treatment machine with the features of claim 1. Preferred embodiments will become apparent from the following dependent claims.

Der wesentliche Vorteil der erfindungsgemäßen Wäschebehandlungsmaschine ist, dass die Dampferzeugungseinrichtung und Pumpe sehr platzsparend und klein bauend innerhalb des Gerätegehäuses angeordnet werden können, da das Wasser zur Dampferzeugung nicht in der kompletten Menge innerhalb der Dampferzeugungseinrichtung bevorratet werden muss. Der Tank für die Bevorratung des Wassers ist hierbei als Funktionsbauteil ausgebildet, welches zusätzlich für die Wassereinspülung für die gemeinsame Düse besonders ausgebildet ist. Somit müssen nur wenige Schläuche zur Verbindung zwischen den be treffenden Komponenten verlegt werden, was einerseits platzsparend und andererseits montagefreundlich ist.The main advantage of the laundry treatment machine according to the invention is that the steam generating device and pump can be arranged very compact and small building within the device housing, since the water for steam generation does not have to be stored in the complete amount within the steam generating device. The tank for the storage of water is in this case formed as a functional component, which is additionally designed in particular for the Wassereinspülung for the common nozzle. Thus, only a few hoses to connect between the be suitable components are laid, which is both space-saving and easy to install.

Erfindungsgemäß ist hierbei vorgesehen, dass der Tank ferner einen als Überlauf ausgebildeten Auslauf umfasst, der über eine Verbindungsleitung unter Umgehung der Pumpe mit der Düse verbunden ist. Somit können die für den Überlauf bereitgestellten Bauteile als integraler Bestandteil des Tanks ausgebildet werden, wodurch sich eine kompakte und einfach zu handhabende Einheit ergibt.According to the invention, it is provided that the tank further comprises an outlet formed as an overflow, which is connected to the nozzle via a connecting line, bypassing the pump. Thus, the components provided for the overflow can be formed as an integral part of the tank, resulting in a compact and easy-to-use unit.

Beim Einsatz der Dampferzeugungseinrichtung in einer Waschmaschine mit einem in dem Gehäuse angeordneten, schwingbeweglich befestigten Laugenbehälter mit einer darin horizontal oder geneigt angeordneten, drehbaren Trommel und einer im Wesentlichen kreisförmigen Laugenbehälteröffnung und einer Dichtungsmanschette, die zur Verbindung zwischen der Gehäuseöffnung und der Laugenbehälteröffnung angeordnet ist, ist es zweckmäßig, die Düse zum Einspülen von Wasser und Einsprühen von Dampf in der Dichtungsmanschette anzuordnen. Somit ist eine gleichmäßige und zuverlässige Dampfbehandlung der Wäsche von der Einfüllöffnung aus sichergestellt, insbesondere, wenn die Düse im oberen Bereich des Dichtrings oder der Einfüllöffnung der Trommel angebracht ist. Die Richtungsangaben beziehen sich auf die betriebsgemäße Aufstellposition der Wäschebehandlungsmaschine.When using the steam generating device in a washing machine with a arranged in the housing, swingably mounted tub with a horizontally or inclined arranged therein, rotatable drum and a substantially circular lye container opening and a gasket for connection is arranged between the housing opening and the tub opening, it is expedient to arrange the nozzle for flushing water and spraying steam in the gasket. Thus, a uniform and reliable steam treatment of the laundry from the filling opening is ensured, in particular when the nozzle is mounted in the upper region of the sealing ring or the filling opening of the drum. The directional information refers to the operational installation position of the laundry treatment machine.

Für eine vorteilhafte Behandlung der Wäsche mit Dampf ist es zweckmäßig, dass die Pumpe eine Förderleistung von 2 bis 7 ml pro sek. hat, die Düse einen Querschnitt von 0,5 cm2 bis 1 cm2 und der Heizkörper eine maximale Leistung von 2 KW besitzt. Um mit dieser geringen Heizleistung eine größere Wärmemenge, hier etwa 30 KJ zu speichern, ist ferner eine Speichermasse vorgesehen, vorteilhafterweise ein Alu-Block von etwa 300 bis 500 Gramm, der vom Heizkörper auf eine Temperatur von 120 bis 200 °C erhitzt wird. Ferner ist es zweckmäßig, dass der Behälter ein Volumen im Bereich zwischen 150 ml bis 400 ml hat. Mit diesen Dimensionierungen kann bei einer geringen elektrischen Leistung genügend Dampf für die Nachbehandlung oder Zusatzbehandlung für eine Wäschebeladung von 1 bis 3 kg erzeugt werden.For an advantageous treatment of the laundry with steam, it is expedient that the pump has a flow rate of 2 to 7 ml per sec. has, the nozzle has a cross section of 0.5 cm 2 to 1 cm 2 and the radiator has a maximum power of 2 KW. In order to store a larger amount of heat, here about 30 KJ with this low heat output, a storage mass is also provided, advantageously an aluminum block of about 300 to 500 grams, which is heated by the heater to a temperature of 120 to 200 ° C. Furthermore, it is expedient that the container has a volume in the range between 150 ml to 400 ml. With these dimensions, sufficient steam for the aftertreatment or additional treatment for a laundry load of 1 to 3 kg can be generated at a low electrical power.

In einer zweckmäßigen Ausführung umfasst der Tank für den Wassereinlauf einen Siphon, der als Ventil wirkt, um zu verhindern, dass Dampf aufgrund eines Überdrucks in der Dampferzeugungseinrichtung durch die Zuführungsleitung in den Einspülkasten entweicht. Dadurch wird sichergestellt, dass während der Wassereinspülung bei geöffnetem Einlassventil der Behälter zuverlässig gefüllt und zum Überlaufen gebracht werden kann, wobei nach dem Schließen des Einlassventils die zu bevorratende Wassermenge im Tank verbleibt. Beim Entleeren des Tanks bleibt der Siphon gefüllt und verschließt dadurch die Einlassöffnung, wodurch zurückdrängender Dampf nicht durch die Einlassleitung in den Einspülkasten bzw. zur freien Fließstrecke entweichen kann.In an expedient embodiment, the tank for the water inlet comprises a siphon, which acts as a valve to prevent steam from escaping through the supply line into the dispenser box due to an overpressure in the steam generator. This ensures that during the Wassereinspülung with open inlet valve, the container can be filled reliably and overflow, leaving after closing the inlet valve, the amount of water to be stored in the tank. When emptying the tank, the siphon remains filled and thereby closes the inlet opening, whereby retracting steam can not escape through the inlet line into the dispenser box or to the free flow path.

In einer vorteilhaften Weiterbildung sind der Siphon und der Überlauf als stegförmige Anformungen an zumindest einer Tankwand ausgebildet. Somit werden diese beiden Funktionsteile als integrale Bestandteile des Tanks auf einfache Weise bereitgestellt.In an advantageous development of the siphon and the overflow are formed as web-shaped projections on at least one tank wall. Thus, these two functional parts are provided as integral parts of the tank in a simple manner.

In einer vorteilhaften Weiterbildung besteht der Tank aus zwei zusammengefügten Schalen, wobei die Anformungen an einer Innenseite einer oder beider Schalen angeordnet sind. Die Herstellung der Schalen, beispielsweise aus Kunststoffmaterial, ist besonders effektiv im Spritzgussverfahren durchzuführen und das Fügen erfolgt mittels Schraub,- Schweiß- oder Klebeverbindung.In an advantageous development of the tank consists of two joined shells, wherein the projections are arranged on an inner side of one or both shells. The production of the shells, for example made of plastic material, is particularly effective in the injection molding process and the joining takes place by means of screw, - welded or glued connection.

Um mit dem als Funktionsbauteil ausgebildeten Tank sowohl die Wassereinspülung im Türbereich als auch die Dampfeinspritzung bereitzustellen, ist der Tank und die Dampferzeugungseinrichtung im Bereich oberhalb des zylinderförmigen Behälters innerhalb des Gehäuses befestigt, wobei der als Überlauf ausgebildete Auslauf unterhalb der Eintrittsöffnung der Dampferzeugungseinrichtung angeordnet ist, bezogen auf die betriebsgemäße Position der Wäschebehandlungsmaschine. Dadurch kann sich der gefüllte Tank nicht über die inaktive Pumpe und die Dampferzeugungseinrichtung ungewollt entleeren.In order to provide both the water injection in the door area and the steam injection with the tank formed as a functional component, the tank and the steam generating device is mounted in the region above the cylindrical container within the housing, wherein the outlet formed as an overflow is arranged below the inlet opening of the steam generating device on the operational position of the laundry treatment machine. As a result, the filled tank can not be unintentionally emptied via the inactive pump and the steam generator.

Insgesamt ist es vorteilhaft, den Tank als flachen Hohlkörper auszubilden und hochkant im Bereich hinter der frontseitigen Wand oder eines frontseitigen Tragteils des Gehäuses anzubringen. Dadurch wird ohnehin vorhandener Platz innerhalb des Gerätegehäuses optimal für den Tank genutzt, so dass andere Komponenten der Maschine nicht verkleinert oder die Geräteabmessungen vergrößert werden müssen.Overall, it is advantageous to form the tank as a flat hollow body and to install edgewise in the area behind the front wall or a front-side supporting part of the housing. As a result, any existing space within the device housing is used optimally for the tank, so that other components of the machine does not need to be reduced or the device dimensions must be increased.

In einer zweckmäßigen Weiterbildung ist der Tank als flacher Hohlkörper ausgebildet, der hochkant im Bereich hinter der frontseitigen Wand oder eines frontseitigen Tragteils des Gehäuses angebracht ist. Somit ist der Tank für den vorhandenen Bauraum innerhalb des Maschinengehäuses optimal ausgebildet bzw. geformt. Durch diese Anordnung kann ferner die Verbindungsleitung zur Düse sehr kurz gehalten werden, da sich der Tank unmittelbar oberhalb der Düse befindet.In an expedient development of the tank is designed as a flat hollow body, which is mounted edgewise in the area behind the front wall or a front-side support member of the housing. Thus, the tank for the available space within the machine housing is optimally formed or shaped. By this arrangement, furthermore, the connection line to the nozzle can be kept very short, since the tank is located directly above the nozzle.

In einer zweckmäßigen Weiterbildung ist die Düse für die Anbindung von zwei Leitungen ausgebildet, wobei eine Leitung für die Zuführung von Dampf und eine Leitung für die Zuführung von Wasser bestimmt ist. Damit werden Verzweigungen auf ein einziges, ohnehin vorhandenes Bauteil reduziert.In an expedient development, the nozzle is designed for the connection of two lines, wherein a line for the supply of steam and a line for the supply of water is intended. This reduces branching to a single, already existing component.
