Die Erfindung betrifft ein Dampfbügeleisen gemäß der Gattung des unabhängigen Patentanspruchs.The invention relates to a steam iron according to the preamble of the independent claim.

Ein gattungsgemäßes Dampfbügeleisen ist in der DE 100 25 233 A1 beschrieben. Das Dampfbügeleisen weist eine Verdampfungskammer, ein Dampfablassventil sowie eine Dampfbügeleisensohle auf. In dieser ist wenigstens eine auf ein zu bügelndes Wäschestück gerichtete Dampföffnung ausgebildet. Durch das Dampfablassventil kann im geöffneten Zustand Dampf aus einer Verdampfungskammer über die zumindest eine Dampföffnung auf das zu bügelnde Wäschestück geleitet werden.A generic steam iron is described in DE 100 25 233 A1. The Steam iron has an evaporation chamber, a steam drain valve and one Steam iron sole on. In this is at least one on a piece of laundry to be ironed directed steam opening. Through the steam drain valve can be opened Condition steam from an evaporation chamber via the at least one steam opening be directed to the laundry to be ironed.

Eine Vorrichtung zur Dampferzeugung, die sich u.a. auch für Dampfbügeleisen eignet, ist weiterhin aus der EP 0 666 451 A1 bekannt. Diese Vorrichtung umfasst einen Heizkörper und einen Dampfkammerkopf, deren Innenwände eine ringförmige Dampfkammer bilden. Dort ist ein rotierendes Flügelrad angeordnet, dem über eine Wasserzuleitung Wasser zugeführt wird. Durch das schnell rotierende Flügelrad wird das Wasser in winzige Tröpfchen zerstäubt und gelangt an die heiße Dampfkammerwand, wo die Wassertropfen verdampfen.A device for generating steam, which among other things. is also suitable for steam irons also known from EP 0 666 451 A1. This device comprises a radiator and a steam chamber head, the inner walls of which form an annular steam chamber. There is a rotating impeller, which receives water via a water supply is fed. The rapidly rotating impeller turns the water into tiny droplets atomizes and reaches the hot steam chamber wall, where the water drops evaporate.

Eine Aufgabe der vorliegenden Erfindung besteht darin, bei einem gattungsgemäßen Dampfbügeleisen mehr Dampf zu erzeugen und seine Gleiteigenschaften zu verbessern.An object of the present invention is in a generic Steam irons produce more steam and improve its sliding properties.

Diese Aufgabe wird mit einem Dampfbügeleisen mit den Merkmalen des unabhängigen Patentanspruchs dadurch gelöst, dass in einer Dampfkammer des Dampfbügeleisens eine zusätzliche Vorrichtung zur Einblasung von Luft vorgesehen ist. Hierzu mündet in die Dampfkammer vorzugsweise wenigstens eine Luftdüse, durch die Luft mit einem geringen Überdruck von bspw. ca. 0,5 bis 1 bar in die Dampfkammer eingeblasen wird. Durch das Einblasen von Luft in die Dampfkammer wird die Zerstäubung von darin eingebrachtem Wasser und/oder Nassdampf verbessert, so dass eine größere Dampfmenge erzeugt werden kann. Die Dosierungsmenge kann somit vergrößert werden. Gleichzeitig kann das Gleiten des Bügeleisens verbessert werden, da durch die größere um feiner verteilte Dampfmenge das Gleiten deutlich gleichmäßiger wird, ähnlich wie mit einem Luftkissen. Zudem tritt der Dampf mit einer höheren Energie aus der Dampfbügeleisensohle aus und dringt tiefer in das Gewebe des zu bügelnden Wäschestücks ein, so dass dieses besser aufgelockert wird. Weiterhin kann bei der Verdampfung eine größere Oberfläche der Bügeleisensohle verwendet werden, so dass die Verdampfung insgesamt gleichmäßiger erfolgt.This task is done with a steam iron with the features of independent Claim solved in that in a steam chamber of the steam iron an additional device for blowing in air is provided. This leads to the Steam chamber preferably at least one air nozzle through which air with a low Overpressure of, for example, approx. 0.5 to 1 bar is blown into the steam chamber. By the Blowing air into the steam chamber will atomize what is introduced therein Water and / or wet steam improved so that a larger amount of steam is generated can be. The dosage amount can thus be increased. At the same time it can Glide of the iron can be improved because of the larger to more finely distributed The amount of steam gliding becomes much more uniform, similar to an air cushion. In addition, the steam emerges from the steam iron soleplate with a higher level of energy penetrates deeper into the fabric of the item to be ironed, so that it is better is loosened up. Furthermore, a larger surface of the soleplate can be used during evaporation be used so that the evaporation is more even overall he follows.

Eine besonders vorteilhafte Wirkung wird erreicht, wenn die wenigstens eine Luftdüse in Nähe eines in die Dampfkammer mündenden Eintropfventils zur Einbringung von Wasser und/oder Nassdampf angeordnet ist. Vorzugsweise ist die wenigstens eine Luftdüse auf eine Auslassöffnung des Eintropfventils gerichtet. Hierdurch erfolgt eine optimale Verteilung des Dampfes in der Dampfkammer, so dass insgesamt auch eine größere Dampfmenge in gleicher Zeit erzeugt werden kann.A particularly advantageous effect is achieved if the at least one air nozzle in Close to a drip valve opening into the steam chamber for the introduction of water and / or wet steam is arranged. The at least one air nozzle is preferably open directed an outlet opening of the drip valve. This ensures an optimal distribution of the steam in the steam chamber, so that overall a larger amount of steam can be generated at the same time.

Eine Ausgestaltung der Erfindung sieht vor, dass die Vorrichtung zur Einblasung von Luft einen von einem kleinen Elektromotor betriebenen Verdichter umfasst. Ein vom Elektromotor angetriebenes Verdichterrad kann Luft aus der Umgebung ansaugen und sie mit einem Überdruck von ca. 0,5 bis 1 bar in die Dampfkammer einblasen. Wenn die Luft an irgend einer Stelle in die Dampfkammer eingeblasen wird, wird dadurch zumindest das Gleiten des Bügeleisens verbessert. Wenn die Luft jedoch am Auslass des Eintropfventils eingeblasen wird, werden deutliche Verbesserungen hinsichtlich der erzeugten Dampfmenge, der Gleiteigenschaften des Bügeleisens sowie der erzielbaren Austrittsenergie des Dampfes erreicht. Beim Anblasen des Auslasses des Eintropfventils wird ein aus diesem austretender Tropfen fein in der Dampfkammer verteilt, wobei die Oberfläche der Verdampfung vergrößert und damit die erzeugte Menge an Dampf erhöht wird.An embodiment of the invention provides that the device for blowing in air a compressor operated by a small electric motor. One from the electric motor driven compressor wheel can suck in air from the environment and it with Blow into the steam chamber at a pressure of approx. 0.5 to 1 bar. When the air comes on at any point in the steam chamber is at least that Sliding iron improved. However, if there is air at the outlet of the drip valve is blown in, there will be significant improvements in the amount of steam generated, the sliding properties of the iron and the achievable exit energy of steam reached. When the outlet of the drip valve is blown, it becomes one emerging droplets finely distributed in the steam chamber, the surface of the Evaporation increases and thus the amount of steam generated is increased.

Eine alternative Ausgestaltung sieht ein Druckluftreservoir im Dampfbügeleisen vor, das eine nachgeordnete Drosseleinrichtung zur Erzeugung des gewünschten konstanten Überdrucks bei der Einleitung in die Dampfkammer aufweist. Das Druckluftreservoir kann bspw. eine auswechselbare Patrone umfassen, die mit einem Überdruck von mehr als 100 bar gefüllt sein kann und die auf diese Weise bei geringer Größe eine relativ lange Betriebsdauer gewährleisten kann. Mit einem solchen auswechselbaren Druckluftreservoir kann gegenüber einem elektromotorisch betriebenen Verdichter der Bauaufwand verringert sowie das für die Vorrichtung zur Einblasung von Luft notwendige zusätzliche Baugewicht reduziert werden.An alternative embodiment provides a compressed air reservoir in the steam iron, the a downstream throttle device for generating the desired constant overpressure has at the introduction into the steam chamber. The compressed air reservoir can For example, include a replaceable cartridge with an overpressure of more than Can be filled 100 bar and in this way with a small size a relatively long Can guarantee operating time. With such an interchangeable compressed air reservoir compared to an electric motor-operated compressor, the construction effort can be reduced and the additional weight required for the device for blowing air be reduced.

Eine weitere Ausgestaltung der Erfindung kann vorsehen, dass zwei oder mehr sehr feine Luftdüsen konzentrisch um das Eintropfventil angeordnet sind und für eine optimale Dampferzeugung durch extrem feine Zerstäubung des mittels des Eintopfventils zugeführten Wassers und/oder Nassdampfes sorgen.A further embodiment of the invention can provide that two or more very fine Air nozzles are arranged concentrically around the drip valve and for optimal Steam generation by extremely fine atomization of the one-pot valve Provide water and / or wet steam.

Insgesamt wird durch die Verwendung des Venturi-Effektes durch die Einblasung von Luft auf die Ausströmöffnung des in der Dampfkammer angeordneten Diffusors die darin erzeugte Dampfmenge erhöht, wodurch die Gleiteigenschaften des Bügeleisens verbessert und die Effektivität beim Glätten der Wäsche erhöht werden kann.Overall, by using the Venturi effect by blowing air on the outflow opening of the diffuser arranged in the steam chamber the generated therein The amount of steam increases, which improves the sliding properties of the iron and the effectiveness in smoothing the laundry can be increased.

Weitere Aspekte und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie aus der nachfolgenden Figurenbeschreibung.Further aspects and advantageous developments of the invention result from the dependent claims and from the following description of the figures.

The invention is explained in more detail below using an exemplary embodiment with reference to the accompanying drawing. It shows:

Figure 2
a detailed schematic view of the device for blowing air into the steam chamber of the iron.

Ein Dampfbügeleisen 10 weist ein an sich bekanntes Gehäuse 12 mit einem Handgriff und einer nach unten gerichteten Dampfbügeleisensohle 16 auf, die beheizbar ist und die unter mehr oder weniger starkem Druck über ein zu bügelndes Wäschestück geschoben wird. Innerhalb des Gehäuses 12 und oberhalb der beheizbaren Dampfbügeleisensohle 16 ist eine Dampfkammer 14 angeordnet, in die mittels eines Eintropfventils 20 Wasser aus einem Wassertank (nicht dargestellt) eingebracht und in kleine Wassertröpfchen fein zerstäubt wird. In der Dampfbügeleisensohle 16 sind mehrere, vorzugsweise eine Vielzahl von Öffnungen 18 vorgesehen, durch die der in der Dampfkammer 14 erzeugte Dampf 40 hindurch treten und in das Wäschestück eindringen kann, um dessen Gewebe aufzulockern und die Bügelergebnisse zu verbessern. A steam iron 10 has a housing 12 known per se with a handle and a downward steam iron sole 16 which is heatable and which pushed under more or less strong pressure over a piece of laundry to be ironed becomes. Inside the housing 12 and above the heatable steam iron sole 16, a steam chamber 14 is arranged, into which water 20 by means of a dropping valve introduced from a water tank (not shown) and fine into small water droplets is atomized. There are several, preferably a plurality, in the steam iron soleplate 16 of openings 18 through which the steam 40 generated in the steam chamber 14th step through and penetrate the laundry to loosen its fabric and improve the ironing results.

Eine Vorrichtung 22 zur Einblasung von Luft in die Dampfkammer 14 umfasst im gezeigten Ausführungsbeispiel wenigstens eine in die Dampfkammer 14 mündende Luftdüse 24, die über eine Verbindungsleitung 30 mit einem Verdichter 26 in Verbindung steht, dessen Verdichterrad von einem Elektromotor 28 angetrieben wird. Da bei einem Dampfbügeleisen 10 ohnehin eine Spannungsversorgung zum Betrieb der Heizung zur Verfügung steht, kann der Elektromotor 28 ohne signifikanten konstruktiven Mehraufwand problemlos über diese Spannungsversorgung betrieben werden. Die wenigstens eine Luftdüse 24 ist mit ihrer Ausströmöffnung vorzugsweise auf eine Auslassöffnung des Eintropfventils 20 gerichtet, wodurch eine wesentlich feinere Verteilung der Wassertröpfchen und damit ein höherer Dampfdurchsatz erreicht werden kann.A device 22 for blowing air into the steam chamber 14 comprises in the shown Embodiment at least one air nozzle 24 opening into the steam chamber 14, which is connected via a connecting line 30 to a compressor 26, the Compressor wheel is driven by an electric motor 28. Because with a steam iron 10 a power supply for operating the heating is available anyway, can the electric motor 28 without any significant additional design effort this power supply can be operated. The at least one air nozzle 24 is included its outflow opening is preferably directed towards an outlet opening of the dropping valve 20, whereby a much finer distribution of the water droplets and thus a higher steam throughput can be achieved.

Eine hier nicht dargestellte erfindungsgemäße Ausgestaltung sieht zwei oder mehr Luftdüsen 24 vor, die konzentrisch um das Eintropfventil 20 angeordnet sind und die jeweils sehr feine Ausströmöffnungen zur Einblasung von Luft in die Dampfkammer 14 aufweisen. Dies kann zu einer weiteren Verbesserung des Dampfdurchsatzes führen. Die Luft wird vorzugsweise mit einem Überdruck von ca. 0,5 bis 1 bar in die Dampfkammer 14 eingeblasen.An embodiment according to the invention, not shown here, sees two or more air nozzles 24 before, which are arranged concentrically around the drip valve 20 and each have very fine outflow openings for blowing air into the steam chamber 14. This can lead to a further improvement in steam throughput. The air is preferably in the steam chamber 14 with an overpressure of approximately 0.5 to 1 bar blown.

Eine hier ebenfalls nicht dargestellte Variante der Erfindung sieht vor, dass anstatt eines elektromotorisch betriebenen Verdichters ein Druckluftreservoir im Gehäuse 12 angeordnet ist, dessen hoher Überdruck vorzugsweise mittels einer Drossel auf den gewünschten Überdruck (0,5 - 1 bar) reduziert. Dieses Druckluftreservoir kann bspw. in Form einer auswechselbaren Patrone ausgebildet sein, die ein sehr geringes Gewicht aufweist und auf diese Weise das Gesamtgewicht des Dampfbügeleisens 10 nur geringfügig erhöht.A variant of the invention, also not shown here, provides that instead of one a compressed air reservoir arranged in the housing 12 by an electric motor-operated compressor is, the high pressure, preferably by means of a throttle to the desired Overpressure (0.5 - 1 bar) reduced. This compressed air reservoir can, for example, in the form of a replaceable cartridge can be formed, which has a very low weight and in this way, the total weight of the steam iron 10 increases only slightly.

Die erfindungsgemäße Vorrichtung 22 zur Einblasung von Luft ermöglicht eine deutliche Verbesserung der Bügelergebnisse, da das Dampfbügeleisen 10 annähernd wie auf einem Luftkissen gleitet, zumindest jedoch seine Gleiteigenschaften verbessert werden. Die durch die Öffnungen 18 vergrößerte Menge an austretendem Dampf 40 tritt gleichzeitig mit höherer Energie aus, wodurch der Dampf 40 tiefer in das zu bügelnde Gewebe eindringt und dieses stärker auflockert. Zudem wird bei der Verdampfung eine größere Oberfläche der Dampfbügeleisensohle 16 beaufschlagt, so dass die Verdampfung insgesamt gleichmäßiger wird. Dies kann insbesondere durch die Verwendung von wenigstens zwei Luftdüsen 24 erreicht werden, die die aus dem Eintropfventil 20 austretenden Wassertröpfchen deutlich besser innerhalb der Dampfkammer 14 verteilen können als das Eintropfventil 20 alleine oder nur eine einzige Luftdüse 24.The device 22 according to the invention for blowing in air enables a clear one Improvement of the ironing results, since the steam iron 10 is almost like on a Air cushion slides, but at least its sliding properties are improved. The through the openings 18 increased amount of escaping steam 40 occurs simultaneously with higher energy, whereby the steam 40 penetrates deeper into the fabric to be ironed and loosens it up more. In addition, there is a larger surface during evaporation the steam iron sole 16 acts on, so that the evaporation as a whole becomes more even. This can be done in particular by using at least two Air nozzles 24 are reached, which the water droplets emerging from the dropping valve 20 can distribute significantly better within the steam chamber 14 than the drip valve 20 alone or only a single air nozzle 24.
