Description

Technisches GebietTechnical area

Die Erfindung befindet sich auf dem Gebiet der Dampfbügelvorrichtungen, insbesondere des Dampfbügeleisens oder der Dampfbügelstation, die eine Bügelsohle, die Dampfaustrittsöffnungen aufweist, und eine Verdampfungskammer umfassen, die durch eine Sohlenplatte, die einen Teil der Bügelsohle bildet, eine Seitenwand und eine obere Platte umgrenzt ist, und in die wahlweise Dampf und/oder Verdampfungsflüssigkeit über mindestens eine erste Einführungsöffnung eingeführt werden können; wobei die Seitenwand in einem Stück mit der oberen Platte ausgeführt ist und eine Deckelbaugruppe bildet.The invention is in the field of steam ironing apparatuses, particularly the steam iron or steam ironing station, comprising a soleplate having steam outlets and an evaporation chamber bounded by a sole plate forming part of the soleplate, a side wall and a top plate and into which optional vapor and / or vaporization liquid may be introduced via at least one first introduction port; wherein the sidewall is integral with the top plate and forms a lid assembly.

Stand der TechnikState of the art

Es sind Dampfbügelvorrichtungen bekannt, insbesondere Dampfbügeleisen oder Dampfbügelstationen, die umfassen: eine Bügelsohle, die eine Sohlenplatte aufweist, die von Dampfaustrittsöffnungen durchquert ist; und ein Dampferzeugungssystem mit einer Verdampfungskammer, die in Verbindung mit den Dampfaustrittsöffnungen steht, die auf der Oberseite der Sohlenplatte eingerichtet ist, und in die wahlweise Verdampfungsflüssigkeit über eine Einführungsöffnung eingeführt werden kann.Steam ironing devices are known, in particular steam irons or steam ironing stations, comprising: a soleplate having a soleplate traversed by steam outlets; and a steam generating system having an evaporation chamber communicating with the steam exit openings provided on the upper surface of the sole plate, and into which optional evaporation liquid can be introduced via an introduction opening.

Zur Vereinfachung der Konstruktion und zur Reduktion der Fertigungskosten ist die Sohlenplatte normalerweise mittels Aluminiumspritzguss in einem Stück ausgeführt. Bei den preiswerteren Dampfbügelvorrichtungen fungiert die Unterseite einer Sohlenplatte dieser Art direkt als Kontaktfläche für die Bügelwäsche. Tatsächlich kann die Unterseite der Sohlenplatte auch zur Verbesserung ihrer Gleiteigenschaften sowie des Aussehens spezialbeschichtet sein, oder es kann darauf zusätzlich eine dünne Metallplatte vorgesehen sein, auch wenn dies die Komplexität der Fertigung und die Herstellungskosten erhöht. Im Allgemeinen weist die Sohlenplatte in der Draufsicht ungefähr die Form eines gleichschenkligen Dreiecks auf. Die Verdampfungskammer ist durch eine Seitenwand und eine obere Wand eingeschlossen. Die Einführungsöffnung für die Verdampfungsflüssigkeit in die Verdampfungskammer befindet sich in der oberen Wand der Verdampfungskammer in einem vorderen, das heißt, zur Spitze weisenden Bereich der Sohlenplatte, gewöhnlich im vorderen Drittel der Sohlenplatte.To simplify construction and reduce manufacturing costs, the soleplate is normally made in one piece by means of aluminum injection molding. In the cheaper steam ironing devices, the underside of a soleplate of this type acts directly as a contact surface for ironing. In fact, the underside of the soleplate may also be specially coated to improve its sliding properties as well as the appearance, or it may additionally be provided with a thin metal plate, although this adds to manufacturing complexity and manufacturing costs. In general, the sole plate in plan view has approximately the shape of an isosceles triangle. The evaporation chamber is enclosed by a side wall and an upper wall. The introduction opening for the evaporation liquid in the evaporation chamber is located in the upper wall of the evaporation chamber in a front, that is, to the tip-facing portion of the sole plate, usually in the front third of the sole plate.

Die Dampfaustrittsöffnungen sind in diesen einfacheren Dampfbügelvorrichtungen hauptsächlich in einer Anordnung aus einer oder mehreren Reihen in Bogen- oder Hufeisenform in den seitlichen Bereichen der Sohlenplatte nahe der Seitenwand gestaltet. Da die Sohlenplatte mittels Aluminiumspritzguss ausgeführt ist, ist es einfach, die Seitenwand vertikal von der Oberseite der Sohlenplatte ausgehend zu spritzen. Auf diese Weise kann die Sohlenplatte mit einer oberen Wand mit relativ einfacher Konstruktion aus Edelstahlblech geschlossen werden, die die Verdampfungskammer verschließt. Dann ist die Verdampfungskammer in ihrem Umfang durch die Seitenwand begrenzt, die sich vertikal von der Oberseite der Sohlenplatte erhebt, und darauf sitzt die obere Wand auf und ist entlang dem Verbindungsumfang mit einer Silikonschnur abgedichtet. Manchmal weist die Verbindung der oberen Wand mit der vertikalen Wand durch einen fehlerhaften Verschluss mit dem Silikon ein kleines Dampfleck auf, und der Dampf entweicht zum Inneren der Vorrichtung und erzeugt elektrische Ausfälle.The steam outlets in these simpler steam ironing devices are designed primarily in an array of one or more rows of bow or horseshoe shape in the lateral regions of the soleplate near the side wall. Since the soleplate is made by aluminum injection molding, it is easy to spray the sidewall vertically from the top of the soleplate. In this way, the soleplate can be closed with a top wall of relatively simple stainless steel sheet construction which closes off the vaporization chamber. Then, the evaporation chamber is bounded in its circumference by the side wall which rises vertically from the top of the sole plate, and the upper wall is seated thereon and sealed with a silicone cord along the connecting periphery. Sometimes, the connection of the upper wall to the vertical wall due to faulty sealing with the silicone has a small steam leak, and the vapor escapes to the interior of the device and generates electrical failures.

Im Dokument GB 2176505 A ist ein Dampfbügeleisen gezeigt, das eine Bügelsohle mit Dampfaustrittsöffnungen und eine Verdampfungskammer aufweist, in die das zu verdampfende Wasser eingeführt wird. Die Verdampfungskammer ist durch eine Sohlenplatte, die einen Teil der Bügelsohle bildet, eine Seitenwand und eine obere Platte begrenzt. Ein Teil der Seitenwand ist in einem Stück mit der oberen Platte ausgeführt und bildet eine Deckelbaugruppe. Mit dieser Gestaltung wird das Problem nicht gelöst, dass Dampfleckagen in das Innere der Vorrichtung eindringen und elektrische Ausfälle hervorrufen.In the document GB 2176505 A a steam iron is shown having a soleplate with steam outlet openings and an evaporation chamber into which the water to be evaporated is introduced. The vaporization chamber is defined by a soleplate forming part of the soleplate, a side wall and an upper plate. A portion of the sidewall is integral with the top panel and forms a lid assembly. With this design, the problem is not solved that steam leaks penetrate into the interior of the device and cause electrical failure.

Außerdem befindet sich die vertikale Wand normalerweise so nah wie möglich am Umfang der Sohlenplatte, um eine geräumigere Verdampfungskammer zu ermöglichen. Auf der Bügelsohle ist der Rest der Bestandteile des Bügeleisens befestigt und ist mit einem Kunststoffgehäuse abgedeckt, das sich in einer sicheren Konstruktion der Vorrichtung im Bereich nahe der Bügelsohle in einem Abstand von der Seitenwand der Verdampfungskammer fern halten muss, um den Kontakt zu vermeiden, da die hohen Temperaturen der Sohle das Gehäuse beschädigen könnten. Daher ist die Form des Gehäuses, und insbesondere die Ästhetik der Vorrichtung, durch die Form der Bügelsohle eingeschränkt.In addition, the vertical wall is normally as close as possible to the perimeter of the soleplate to allow for a more spacious evaporation chamber. On the soleplate, the rest of the components of the iron is fixed and is covered with a plastic housing, which must keep in a safe construction of the device in the area near the soleplate at a distance from the side wall of the evaporation chamber in order to avoid contact since the high temperatures of the sole could damage the housing. Therefore, the shape of the Housing, and in particular the aesthetics of the device, limited by the shape of the sole plate.

Dass sich der Umfang der Seitenwand nach außerhalb der Verdampfungskammer erstreckt und eine Krempe bildet, ist so zu verstehen, dass die Krempe einen Winkel von 90° oder weniger mit der Senkrechten an der Sohlenplatte nach außerhalb der Dampfkammer bildet. Vorzugsweise erstreckt sie sich in der Ebene der Sohlenplatte und bildet eine Bügelsohle mit größerer Fläche, obwohl sie, wenn der Winkel kleiner ist oder sie nach oben gekrümmt ist, eine Bügelsohle mit gekrümmten Rändern bilden kann.Since the plate thickness or thickness of the soleplate, depending on the structural embodiment, may vary locally, in the sense of the invention "upper surface" of the soleplate is to be understood as the upper surface or the level of the soleplate which is facing upward it faces the rest of the ironing device. That the perimeter of the sidewall extends outside the vaporization chamber and forms a brim is understood to mean that the brim makes an angle of 90 ° or less with the perpendicular to the soleplate outwardly of the vapor chamber. Preferably, it extends in the plane of the soleplate and forms a larger area soleplate although, if the angle is smaller or curved upwardly, it may form a soleplate with curved edges.

Die Sohlenplatte sitzt auf dem Umfang der Seitenwand so auf, dass sich die Deckelbaugruppe mit der Sohlenplatte durch einfachen Kontakt verbindet, aber es kann eine dichte Versiegelung mittels Silikon hergestellt sein. In dieser Gestaltung der Verdampfungskammer nach der Erfindung sind die Dampfverluste durch die Verbindungslinie zwischen der Deckelbaugruppe und der Sohlenplatte weniger relevant, da sie nicht zum Inneren der Vorrichtung gerichtet sind. Die dichte Versiegelung gegen Flüssigkeit und Dampf bzw. ein entsprechender Verschluss kann ein angeformter Bestandteil der Sohlenplatte sein. Natürlich sind auch getrennte oder zusätzliche Abdichtungselemente möglich, die direkt oder indirekt (zum Beispiel über ein Zwischenelement) mit der Sohlenplatte verbunden sein können. Der Verschluss bzw. das Abdichtungselement muss beständig gegen die Bügeltemperatur sein. Dies bedeutet, dass diese Elemente so temperaturbeständig gestaltet sein müssen, dass bei den Temperaturen, die beim Bügeln bzw. Dampfbügeln auftreten (im Allgemeinen ungefähr 70° C - 190° C, obwohl unter bestimmten Umständen auch bis zu 260° C), die Flüssigkeits- und Dampfdichtigkeit aufrecht erhalten ist. Als getrenntes oder zusätzliches Dichtungselement kann, zum Beispiel auch in Kombination mit anderen mechanischen Bauteilen, insbesondere eine gießbare, aushärtbare Dichtungsmasse, zum Beispiel eine Silikonmasse, verwendet werden. Natürlich ist die Erfindung nicht auf ein derartiges separates Dichtungselement beschränkt.The soleplate is seated on the perimeter of the sidewall so that the lid assembly bonds to the soleplate by simple contact, but a tight silicone seal may be made. In this configuration of the evaporation chamber according to the invention, the vapor losses through the connection line between the cover assembly and the soleplate are less relevant because they are not directed towards the interior of the device. The tight seal against liquid and vapor or a corresponding closure may be an integral part of the sole plate. Of course, separate or additional sealing elements are also possible, which may be connected directly or indirectly (for example via an intermediate element) to the soleplate. The closure or the Sealing element must be resistant to the ironing temperature. This means that these elements must be designed to be temperature resistant so that at the temperatures encountered during ironing (generally about 70 ° C - 190 ° C, although in some circumstances up to 260 ° C), the liquid - And steam-tightness is maintained. As a separate or additional sealing element, for example, in combination with other mechanical components, in particular a castable, hardenable sealing compound, for example a silicone composition, can be used. Of course, the invention is not limited to such a separate sealing element.

Das Heizelement ist vorzugsweise ein Röhrenwiderstand, der in die Deckelbaugruppe in einem Bereich nahe dem Umfang der Seitenwand eingebettet ist, wo er mit der Krempe verbunden ist. Auf diese Weise überträgt es die Wärme durch Kontakt mit der Sohlenplatte und erleichtert das Verdampfen der Bügelflüssigkeit.The heating element is preferably a tube resistor embedded in the lid assembly in an area near the periphery of the side wall where it is connected to the rim. In this way it transfers the heat by contact with the soleplate and facilitates the evaporation of the ironing fluid.

In verschiedenen Ausführungsformen der Erfindung können die Dampfaustrittsöffnungen in der Sohlenplatte und/oder zwischen der Sohlenplatte und dem Umfang der Seitenwand und/oder in der Krempe angeordnet sein.In various embodiments of the invention, the steam outlet openings may be arranged in the sole plate and / or between the sole plate and the circumference of the side wall and / or in the brim.

Und in den Ausführungsformen, in denen die Bügelsohle mit einer Sohlenabdeckung mit Dampfaustrittsmündungen verkleidet ist, können diese direkt über die Sohlenplatte mit der Verdampfungskammer in Verbindung stehen, oder auch ist zwischen der Bügelsohle und der Sohlenabdeckung eine erste Dampfverteilungskammer ausgebildet, die mit den Dampfaustrittsmündungen und der Verdampfungskammer über die Dampfaustrittsöffnungen verbunden ist.And in the embodiments in which the soleplate is covered with a sole cover with steam outlet mouths, they can be directly on the sole plate with the evaporation chamber in conjunction, or between the soleplate and the sole cover a first vapor distribution chamber is formed with the steam outlet and the mouth Evaporation chamber is connected via the steam outlet openings.

Es ist auch vorgesehen, dass zwischen der Bügelsohle und der Sohlenabdeckung eine zweite Dampfverteilungskammer ausgebildet ist, die mit den Dampfaustrittsmündungen und mit einer zweiten Einfüllöffnung verbunden ist. In diesem Fall ist es besonders vorteilhaft, da es möglich ist, das einzurichten, was die "Super-Vapor"-Funktion genannt wird, da das Wasser nicht in die Verdampfungskammer eintritt, sondern direkt zur zweiten Verteilungskammer geleitet wird, die zumindest teilweise unterhalb des Heizelements verläuft. Auf diese Weise verdampft eine große Menge an Wasser in geringer Zeit.It is also envisaged that between the soleplate and the sole cover, a second steam distribution chamber is formed, which is connected to the steam outlet and a second filling opening. In this case, it is particularly advantageous, since it is possible to set up what is called the "super-vapor" function, since the water does not enter the evaporation chamber, but is directed directly to the second distribution chamber, which is at least partially below the Heating element runs. In this way, a large amount of water evaporates in a short time.

Und in einer weiteren Ausführungsform ist zwischen der Bügelsohle und der Sohlenabdeckung eine dritte Dampfverteilungskammer ausgebildet ist, die mit den Dampfaustrittsmündungen und mit einem Auslass der Verdampfungskammer verbunden ist. In dieser Ausführungsform weist die Verdampfungskammer keine Dampfaustrittsöffnungen auf, da der gesamte Dampf durch den Auslass austritt, und mit der Verteilungskammer verbunden ist, die sich unterhalb der Krempe und teilweise des Heizelements befindet.And in another embodiment, a third steam distribution chamber is formed between the soleplate and the sole cover, which is connected to the steam exit orifices and to an outlet of the evaporation chamber. In this embodiment, the vaporization chamber does not have any vapor outlets because all of the vapor exits through the outlet and is connected to the distribution chamber, which is below the rim and partially the heating element.

In einer vereinfachten Verbindungsform kann die Deckelbaugruppe an der Sohlenplatte mittels einer Schraubverbindung befestigt sein, wobei in einer Form die Schraubverbindung mindestens eine Schraube aufweist, die durch eine Durchgangsöffnung durch die Sohlenplatte geht und in die Innenseite der Deckelbaugruppe geschraubt ist, oder auch umgekehrt die Schraubverbindung mindestens eine Schraube aufweist, die ein in den Deckel gehendes Loch durchdringt und in die Oberseite der Sohlenplatte geschraubt ist. In die Verbindungslinie zwischen beiden kann Dichtungsmaterial eingefügt sein oder nicht.In a simplified form of connection, the cover assembly may be secured to the soleplate by means of a threaded connection, in one form the threaded connection having at least one screw passing through the soleplate through a through-opening and screwed into the inside of the cover assembly, or conversely at least the threaded connection a screw penetrating a hole in the cover and screwed into the top of the sole plate. In the connecting line between the two sealing material may be inserted or not.

In einer vereinfachten Ausführungsform sind die obere Wand, die Seitenwand und die Krempe einstückig mittels eines Aluminium-Spritzgussverfahrens ausgeführt, wodurch die Deckelbaugruppe in derselben Form ausgebildet ist, wie die Sohlenplatte ausgeführt ist, wodurch die unterschiedlichen Ausdehnungskoeffizienten vermieden sind, wenn sie aus verschiedenen Materialien wären.In a simplified embodiment, the top wall, the side wall and the rim are integrally formed by means of an aluminum injection molding process, whereby the cover assembly is formed in the same shape as the sole plate is made, whereby the different expansion coefficients are avoided if they were made of different materials ,

Um der Konstruktion des Kunststoffgehäuses, das das Äußere der Bügelvorrichtung um den Bereich der Bügelsohle abdeckt, größere Flexibilität zu geben, ist es vorgesehen, dass zumindest das Innere oder die gesamte Seitenwand mindestens teilweise zum Inneren der Verdampfungskammer zumindest an einem Teil des Umfangs der Deckelbaugruppe geneigt ist, wodurch dem Äußeren der Seitenwand eine Gestaltung zweckmäßigerer Form gegeben werden kann, wie zum Beispiel gekrümmt oder eben, und dass das Gehäuse nahe zu ihr gestaltet werden kann, jedoch ohne sie zu berühren. Dies ergibt auch den Vorteil, über Dampfaustrittsöffnungen näher am Umfang der Sohlenplatte zu verfügen, da beim Verringern der Höhe der Deckelbaugruppe ohne Berühren des Kunststoffs des Gehäuses die Oberfläche der Verdampfungskammer auf der Sohlenplatte vergrößert werden kann, wodurch Dampf bis zu Stellen der Unterseite der Sohlenplatte gebracht werden kann, an die die Bügelvorrichtungen nach dem Stand der Technik nicht gelangen, und somit die Bügelqualität verbessert werden kann. Es ist zu erwähnen, dass eine Deckelbaugruppe mit einer geneigten Seitenwand wie diejenige nach der Erfindung durch das Aluminium-Spritzgusssystem sehr einfach herzustellen ist, da die Form keine komplizierten Schieber oder Spritzsysteme benötigt, die benötigt würden, wenn man beabsichtigte, diese geneigten Wände einstückig mit der Sohlenplatte zu fertigen.In order to give greater flexibility to the construction of the plastic housing covering the exterior of the ironing device around the area of the soleplate, it is contemplated that at least the interior or the entire sidewall at least partially sloped towards the interior of the evaporation chamber at least on a portion of the periphery of the cover assembly is, whereby the exterior of the side wall can be given a design of more appropriate shape, such as curved or flat, and that the housing can be made close to her, but without touching it. This also provides the advantage of having steam vents nearer the perimeter of the soleplate, as reducing the height of the lid assembly without contacting the plastic of the housing can increase the surface area of the vaporizing chamber on the soleplate, thereby providing steam to the underside of the soleplate can be brought to which the ironing devices of the prior art do not arrive, and thus the ironing quality can be improved. It should be noted that a lid assembly having a sloping sidewall, such as that of the invention, is very easy to manufacture by the aluminum injection molding system, since the mold does not require the complicated slide or spray systems that would be required if these inclined walls were to be used in one piece to manufacture the sole plate.

Auch eine Aufgabe der Erfindung ist eine Dampfbügelvorrichtung, insbesondere eines Dampfbügeleisens oder einer Dampfbügelstation, die eine mit einem Heizelement heizbare und mit einer Sohlenabdeckung, die Dampfaustrittsmündungen aufweist, verkleidete Bügelsohle umfasst, wobei zwischen der Bügelsohle und der Sohlenabdeckung eine vierte Dampfverteilungskammer ausgebildet ist, die mit den Dampfaustrittsmündungen verbunden ist, wobei in die vierte Dampfverteilungskammer wahlweise Dampf und/oder Verdampfungsflüssigkeit über mindestens eine zweite Einführungsöffnung eingeführt werden können. In dieser Form kann eine Dampfverteilungs- und Erzeugungskammer mit einer besonders hohen Dampferzeugung in einfacher Form ausgeführt sein.Also, an object of the invention is a steam ironing device, in particular a steam iron or a steam ironing station comprising a heatable with a heating element and having a sole cover, the steam outlet mouths, covered soleplate, wherein between the soleplate and the sole cover, a fourth steam distribution chamber is formed with the steam outlet orifices is connected, wherein in the fourth steam distribution chamber optionally steam and / or evaporation liquid can be introduced via at least one second introduction opening. In this form, a steam distribution and production chamber with a particularly high steam generation can be designed in a simple form.

Beschreibung der bevorzugten AusführungsformDescription of the preferred embodiment

In Fig. 1 ist eine Draufsicht der Unterseite einer Deckelbaugruppe 12 einer Bügelsohle 4 gezeigt. Die Deckelbaugruppe 12 ist aus Aluminiumguss ausgeführt, in den das rohrförmige, U-förmige Heizelement 22 eingebettet ist, das zum Inneren der Dampfbügelvorrichtung weist. Das Innere der Vorrichtung ist durch ein Gehäuse (in den Figuren nicht gezeigt) eingeschlossen, das einen Griff aufweist, mit dem der Benutzer die Vorrichtung bedienen kann, indem er sie auf der zu bügelnden Kleidung oder dem Wäschestück verschiebt. In den Dampfbügelvorrichtungen von Typ Dampfbügeleisen befindet sich im Inneren der Wassertank, der oberhalb der Bügelsohle angeordnet ist und der Verdampfungskammer 10 Dampfflüssigkeit W durch eine erste Einführungsöffnung 14a zuführt, die in der oberen Platte 15 der Kammer 10 vorhanden ist.In Fig. 1 is a plan view of the underside of a cover assembly 12 of a soleplate 4 is shown. The lid assembly 12 is made of cast aluminum, in which the tubular, U-shaped heating element 22 is embedded, which faces the interior of the steam ironing device. The interior of the device is enclosed by a housing (not shown in the figures) which has a handle with which the user can manipulate the device by sliding it on the clothing or garment to be ironed. In the steam iron type steam ironing apparatuses, inside is the water tank disposed above the soleplate and supplying vaporization liquid W to the evaporation chamber 10 through a first introduction opening 14a provided in the upper plate 15 of the chamber 10.

Die obere Platte 15 ist mit der Krempe 20 in einer anderen Ebene über die Seitenwand 13 an deren Umfang 13a verbunden. Die Verdampfungskammer ist mit einer Sohlenplatte 2 wie derjenigen der Fig. 2 verschlossen. Sie können mittels einer Schraubverbindung 19 mit einer Schraube verbunden sein, die durch ein Durchgangsloch 17 in der oberen Platte 15 geht und in die Oberseite 2a der Sohlenplatte 2 geschraubt ist, wie in Fig. 3 zu sehen, oder die Sohlenplatte kann auch an die Deckelbaugruppe 12 mit einem temperaturfesten Klebstoff, wie etwa Silikon, angeklebt sein, oder beide Formen gleichzeitig.The upper plate 15 is connected to the brim 20 in another plane via the side wall 13 at its periphery 13a. The evaporation chamber is with a sole plate 2 as that of the Fig. 2 locked. They can be connected by means of a screw 19 with a screw which passes through a through hole 17 in the upper plate 15 and is screwed into the upper surface 2a of the sole plate 2, as in Fig. 3 or the soleplate may also be adhered to the lid assembly 12 with a temperature resistant adhesive such as silicone, or both forms simultaneously.

In der Ausführungsform der Figuren 1 bis 3 ist die durch die Deckelbaugruppe 12 mit der Sohlenplatte 2, die die Verdampfungskammer 10 verschließt, gebildete Bügelsohle 4 durch eine Sohlenabdeckung 24 verkleidet und vorzugsweise mit ihr mit temperaturfestem Klebstoff verbunden. In dieser Ausführungsform weist die Bügelsohle zwei Dampfverteilungskammern 28b und 28c auf. Eine davon, die dritte Dampfverteilungskammer, in die der Dampf von der Verdampfungskammer 10 gelangt, befindet sich auf der Unterseite der Krempe 20 der Bügelsohle 4 und ist durch die Sohlenabdeckung 24 abgedeckt. Die Verdampfungskammer 10 weist eine erste Einführungsöffnung 14a, durch die die Verdampfungsflüssigkeit oder der Dampf W eintritt, und einen Auslass 30 auf, durch den der Dampf durch eine Leitung (nicht gezeigt) austritt, die der gestrichelten Linie der Fig. 3 folgt und durch eine Dampfaustrittsöffnung 6 mit der dritten Dampfverteilungskammer 28c verbunden ist. Der Dampf verlässt die dritte Dampfverteilungskammer 28c durch die Dampfaustrittsmündungen 26, die die Sohlenabdeckung durchqueren.In the embodiment of the FIGS. 1 to 3 For example, the soleplate 4 formed by the lid assembly 12 with the sole plate 2 closing the vaporization chamber 10 is covered by a sole cover 24, and preferably bonded to it with temperature-resistant adhesive. In this embodiment, the soleplate has two steam distribution chambers 28b and 28c. One of them, the third steam distribution chamber into which the steam passes from the evaporation chamber 10, is located on the underside of the brim 20 of the soleplate 4 and is covered by the sole cover 24. The vaporization chamber 10 has a first introduction port 14a through which the vaporization liquid or vapor W enters, and an outlet 30 through which the vapor exits through a conduit (not shown) corresponding to the broken line of FIG Fig. 3 follows and is connected by a steam outlet opening 6 with the third steam distribution chamber 28c. The steam exits the third steam distribution chamber 28c through the steam exit orifices 26 that traverse the sole cover.

Die andere Kammer, die zweite Dampfverteilungskammer 28b, ist in die Oberseite 2b der Sohlenplatte 2 vertieft und durch Verschließen gegen die Unterseite der Deckelbaugruppe 12 kanalisiert. In diese Kammer wird Verdampfungsflüssigkeit W durch die zweite Einführungsöffnung 14b über die Deckelbaugruppe 12 eingeführt, die direkt in die Verteilungskammer 28b mündet. Diese Kammer verläuft durch den Umfang der Sohlenplatte 2 gerade unterhalb des Heizelements 22 bis zur Dampfaustrittsöffnung 6 der Sohlenplatte 2, wo sich die Dampfaustrittsmündungen 26 befinden. Mit dieser zweiten Dampfverteilungskammer 28b kann ein besonders großer Dampfstrom in kurzem Zeitraum erzeugt werden. In derselben Form wie die zweite Kammer in die Oberseite der Sohlenplatte vertieft und durch die Unterseite der Deckelbaugruppe kanalisiert ist, könnte sie entgegengesetzt sein, das heißt, in die Unterseite der Deckelbaugruppe vertieft und durch die Oberseite der Sohlenplatte kanalisiert sein.The other chamber, the second steam distribution chamber 28b, is recessed in the top 2b of the sole plate 2 and channeled by closing against the bottom of the lid assembly 12. In this chamber, evaporation liquid W is introduced through the second introduction opening 14b via the cover assembly 12, which opens directly into the distribution chamber 28b. This chamber extends through the circumference of the sole plate 2 just below the heating element 22 to the steam outlet opening 6 of the sole plate 2, where the steam outlet orifices 26 are located. With this second steam distribution chamber 28b, a particularly large vapor flow can be generated in a short period of time. In the same shape as the second chamber recessed into the top of the soleplate and channeled through the bottom of the lid assembly, it could be opposite, that is, recessed into the bottom of the lid assembly and channeled through the top of the soleplate.

Eine andere Form, diesen Dampfstrom in ähnlicher Form zu erzeugen, ist in den Figuren 5 bis 7 gezeigt, wo die vierte Dampfverteilungskammer 28d in die Unterseite der Deckelbaugruppe 12 vertieft und auf dieselbe Weise wie in der vorherigen Ausführungsform durch die Sohlenabdeckung 24 abgedeckt und kanalisiert ist und unterhalb des Heizelements 22 bis zu den Dampfaustrittsmündungen 26 verläuft. Zu ihr gelangt die Verdampfungsflüssigkeit oder der Dampf W direkt durch die zweite Einführungsöffnung 14b, die im Unterschied zur vorherigen Ausführungsform direkt mit der vierten Dampfkammer 28d verbunden ist.Another way to produce this vapor stream in similar form is in the FIGS. 5 to 7 4, where the fourth steam distribution chamber 28d is recessed into the underside of the cover assembly 12 and is covered and channeled by the sole cover 24 in the same manner as in the previous embodiment and extends below the heating element 22 to the steam exit orifices 26. To her the evaporation liquid or vapor W passes directly through the second introduction opening 14b, which is directly connected to the fourth steam chamber 28d in contrast to the previous embodiment.

In Fig. 4 ist eine weitere Bügelsohle 4 nach der Erfindung in der Schnittansicht dargestellt, bei der die obere Platte 15 mit der Krempe 20 in einer anderen Ebene über die Seitenwand 13 an deren Umfang 13a verbunden ist. Die Verdampfungskammer ist mit einer Sohlenplatte 2 verschlossen; sie können mittels einer Schraubverbindung 19 mit einer Schraube verbunden sein, die durch ein Durchgangsloch 121 in der Sohlenplatte 2 geht und in die Oberseite der oberen Platte 15 der Verdampfungskammer 10 geschraubt ist. In der Ausführungsform der Fig. 4 ist die durch die Deckelbaugruppe 12 mit der Sohlenplatte 2, die die Verdampfungskammer 10 verschließt, gebildete Bügelsohle 4 durch eine Sohlenabdeckung 24 verkleidet und vorzugsweise mit temperaturfestem Klebstoff mit ihr verbunden. In dieser Ausführungsform weist die Bügelsohle eine Dampfverteilungskammer 28a auf. Die Verdampfungskammer 10 weist eine erste Einführungsöffnung 14a, durch die die Verdampfungsflüssigkeit oder der Dampf W eintritt, und mehrere Dampfaustrittsöffnungen 6 in Form von Kanälen auf, die zwischen der Sohlenplatte 2 und der Deckelbaugruppe 12 gerade unterhalb des Heizelements 22 ausgebildet sind und durch die der Dampf bis zur ersten Dampfverteilungskammer 28a steigt. Die Kammer 28a verläuft zum hinteren Teil der Bügelsohle 2 unterhalb des Heizelements, und von ihr verzweigen sich Kanäle, die den Dampf zu Dampfaustrittsmündungen 26 bringen, die die Sohlenabdeckung durchqueren. Diese Gestaltung der Bügelsohle muss nicht unbedingt mit der Sohlenabdeckung verkleidet sein, da die Dampfaustrittsöffnungen 6 den Dampf korrekt durch die Bügelsohle verteilen können.In Fig. 4 a further soleplate 4 according to the invention is shown in the sectional view, in which the upper plate 15 is connected to the brim 20 in another plane via the side wall 13 at its periphery 13a. The evaporation chamber is closed with a sole plate 2; they may be connected by means of a screw 19 with a screw which passes through a through hole 121 in the sole plate 2 and is screwed into the top of the upper plate 15 of the evaporation chamber 10. In the embodiment of the Fig. 4 For example, the soleplate 4 formed by the lid assembly 12 with the sole plate 2 closing the vaporization chamber 10 is covered by a sole cover 24 and preferably bonded to it with temperature-resistant adhesive. In this embodiment, the soleplate has a steam distribution chamber 28a. The evaporation chamber 10 has a first introduction opening 14a through which the evaporation liquid or vapor W enters, and a plurality of steam exit openings 6 in the form of channels formed between the sole plate 2 and the lid assembly 12 just below the heating element 22 and through which the steam rises to the first steam distribution chamber 28a. The chamber 28a extends to the rear of the soleplate 2 below the heating element, and from it branch channels that bring the steam to steam exit orifices 26 that traverse the sole cover. This design of the soleplate does not necessarily have to be clad with the sole cover, since the steam outlet openings 6 can distribute the steam correctly through the soleplate.

In jeder der Ausführungsformen kann die Verdampfungskammer 10 Innenwände 18 aufweisen, um die Verdampfungsflüssigkeit und/oder den Dampf durch das Innere der Kammer zu leiten und sein Verdampfen zu erleichtern.In each of the embodiments, the vaporization chamber 10 may include interior walls 18 for directing the vaporization liquid and / or vapor through the interior of the chamber and facilitating its vaporization.

Jede der Dampfverteilungskammern 28a, 28b, 28c, 28d kann im Zickzack oder als Labyrinth gestaltet sein, um die Strecke des Wassers oder Dampfes W zu vergrößern und sicherzustellen, dass es verdampft oder dampfförmig bleibt, vor allem, wenn sie unterhalb des Heizelements 22 verläuft. Dies ist leicht herzustellen, da die Sohlenplatte 2 und die Deckelbaugruppe 12 mit einem Metallgussverfahren gefertigt werden.Each of the vapor distribution chambers 28a, 28b, 28c, 28d may be zigzagged or labyrinthed to increase the distance of the water or vapor W and to ensure that it remains vaporized or vaporous, especially when below of the heating element 22 extends. This is easy to manufacture since the soleplate 2 and the lid assembly 12 are fabricated by a metal casting process.

Die Auflage der Sohlenplatte 2 in der Deckelbaugruppe 12, die die Verdampfungskammer bildet, kann gestuft sein, wie in Fig. 3 zu sehen, oder nicht, wie in Fig. 7 zu sehen, abhängig von der Gestaltung der Dampfverteilungskammern. Der große Vorteil einer Bügelvorrichtung mit einer Bügelsohle dieser Art ist es, dass kein dichter Verschluss in der oberen Platte der Dampfkammer wie bei den Bügeleisen nach dem Stand der Technik erforderlich ist.The support of the sole plate 2 in the lid assembly 12, which forms the evaporation chamber, may be stepped, as in FIG Fig. 3 to see, or not, as in Fig. 7 see, depending on the design of the steam distribution chambers. The great advantage of an ironing device with a soleplate of this type is that no tight seal is required in the upper plate of the steam chamber as in the prior art irons.

Jede der Dampfverteilungskammern gilt für Dampfbügeleisen mit in die Vorrichtung eingebautem Wasserbehälter oder für Bügelstationen, bei denen die Dampferzeugung in einem separaten Boilerspeicher erfolgt. Beim Dampfbügeleisen muss das Heizelement ausreichend leistungsfähig sein, um das gesamte Wasser zu verdampfen, das in die Verdampfungskammer und in die Dampfverteilungskammern eintritt, und bei den Bügelstationen, um den gesamten Dampf dampfförmig zu halten, der in diese Kammern gelangt.Each of the steam distribution chambers applies to steam irons with built-in water tank or for ironing stations, where the steam generation takes place in a separate boiler storage. With the steam iron, the heating element must be sufficiently powerful to vaporize all of the water entering the vaporization chamber and vapor distribution chambers, and the ironing stations, to vaporize all of the vapor entering these chambers.
