Description

Dampfbügeleisen steam iron
5 Die Erfindung betrifft ein elektrisch beheiztes Bügeleisen, nämlich Dampfbügeleisen nach dem Oberbegriff des Anspruchs 1.5 The invention relates to an electrically heated iron, namely steam iron according to the preamble of claim 1.
Bei derartigen bekannten Bügeleisen nimmt eine Bügelsohle aus Aluminium einen elektrischen Heizkörper auf, der auch alsIn such known irons, an aluminum soleplate accommodates an electric heater, which is also known as
10 Heizeinsatz bezeichnet wird und mit ihr in wärmeleitender Verbindung steht. Bei einer Ausbildung des Bügeleisens als Dampfbügeleisen sind oben aus der Bugelsohle ferner eine Dampfkammer, Dampfstoßkanäle und ein Dampflabyrinth ausgeformt, welches über Dampflöcher zu einer Lauffläche der Bü-10 heating insert is referred to and is in heat-conducting connection with it. When the iron is designed as a steam iron, a steam chamber, steam boost channels and a steam labyrinth are also formed from the top of the iron, which is connected to a running surface of the iron via steam holes.
15 gelsohle geöffnet ist. Zur guten Wärmeübertragung ist die Bügelsohle aus Aluminium gefertigt. Um die Gleitfähigkeit zu verbessern, die Kratzfestigkeit zu erhöhen oder aus ästhetischen Gründen ist die Bügelsohle mit einer dünnen Ξtahlfolie ummantelt oder auf ihrer Unterseite mit einer zusätzlichen 15 soleplate is open. The soleplate is made of aluminum for good heat transfer. In order to improve the gliding ability, to increase the scratch resistance or for aesthetic reasons, the soleplate is covered with a thin steel foil or on the underside with an additional one
20 Sohlenplatte aus Stahl versehen, die eine Dicke von einigen Millimetern aufweisen kann. Diese Beschichtung bzw. Ummante- lung oder die zusätzliche Sohlenplatte aus Stahl haben jedoch den grundsätzlichen Nachteil einer gegenüber Aluminium geringeren Wärmeleitfähigkeit. Diese verhältnismäßig schlechte 5 Wärmeleitfähigkeit hat zur Folge, daß die Wärmeübertragung zwischen der Heizung des Bügelkörpers und einem zu bügelnden Bügelgut zeitlich verzögert erfolgt. Dies macht sich vor allem im Bereich der Sohlenspitze beim Bügeln von Kanten, Biesen, Falten störend bemerkbar, wobei die Temperatur der n Sohlenspitze stark sinken kann.20 sole plate made of steel, which can have a thickness of a few millimeters. However, this coating or sheathing or the additional sole plate made of steel have the fundamental disadvantage of a lower thermal conductivity than aluminum. This relatively poor thermal conductivity has the consequence that the heat transfer between the heating of the ironing body and an ironing item to be ironed is delayed. This is particularly noticeable in the area of the sole tip when ironing edges, tucks, folds, whereby the temperature of the n sole tip can drop sharply.
Zum Stand der Technik gehört bereits ein elektrisches Bügeleisen bestehend aus Bugelsohle mit elektrischem Heizkörper und einem Haubengriffteil, der mit Abstand über der Bügelsoh- ,- le angeordnet ist und bei dem zwischen der Haube des Hauben- griffteils und der Bügelsohle im Bereich der Bügeleisenspitze ein zweischenkeliger Abstandshalter angeordnet ist (DE-G 97 17 313.1) . An den vorderen oberen Bereich des Abstandshalters kann eine Haltenase angeformt sein, die im Einbauzustand eine Haubenspitze eines Haubengriffteils übergreift. Der Abstandshalter soll eine Verbindung von thermoplastischen Hau- bengriffteilen mit metallenen Bügelsohlen ohne einen Luftspalt im Bereich der Bügeleisenspitze ermöglichen, der normalerweise für den Haubenteil als Hitzeschild gegen die von der Bügelsohle ausgehende Wärme dient, und somit den Nachteil des Luftspalts vermeidet, daß sich zwischen Haube und Bügelsohle Bänder, Schleifen, Knöpfe, Schnallen oder ähnliche Accessoires des Bügelguts festklemmen. Damit der Abstandshalter die Wärmeabschirmfunktion des Luftspalts zu der Haube behält, ist klar, daß der Abstandshalter aus schlecht wärmeleitendem Material bestehen muß. Das elektrisch beheizte Bügeleisen mit Abstandshalter weist also hinsichtlich der unerwünscht starken Abkühlung der Bügeleisenspitze den gleichen Nachteil auf wie die weiter oben erörterten bekannten Dampfbügeleisen ohne solchen Abstandshalter.The state of the art already includes an electric iron consisting of a soleplate with an electric heating element and a hood handle part, which is arranged at a distance above the soleplate, and in which a two-legged part is located between the hood part of the handlebar and the soleplate in the area of the iron tip Spacer is arranged (DE-G 97 17 313.1). A retaining lug can be integrally formed on the front upper region of the spacer, which engages over a hood tip of a hood handle part in the installed state. The spacer is intended to enable the connection of thermoplastic hood handle parts to metal soleplates without an air gap in the area of the iron tip, which normally serves as a heat shield for the hood part against the heat emanating from the soleplate, and thus avoids the disadvantage of the air gap that there is between the hood and soleplate Clamp ribbons, bows, buttons, buckles or similar accessories of the ironing material. So that the spacer maintains the heat shielding function of the air gap to the hood, it is clear that the spacer must consist of poorly heat-conducting material. The electrically heated iron with a spacer thus has the same disadvantage with regard to the undesirably strong cooling of the iron tip as the known steam iron without such a spacer discussed above.
Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein elektrisch beheiztes Dampfbügeleisen der eingangs genannten Gattung unkompliziert so auszubilden, daß im Bereich der Sohlenspitze an der Lauffläche einer zusätzlichen Sohlenplatte aus Stahl oder einer Stahl-Beschichtung der Bügelsohle kein störender Temperaturabfall auftritt, wenn der Sohlenspitze durch Bügeln Wärme entzogen wird. Dies soll im Gebrauch des Bügeleisens zu besseren, schnelleren und gleichmäßigeren Bügelergebnissen führen. Die Vorteile der beschichteten oder mit einem Belag bzw. einer zusätzlichen Sohlenplatte veredelten Lauffläche des Bügeleisens sollen dabei erhalten bleiben.In contrast, the present invention has for its object to form an electrically heated steam iron of the type mentioned in such a way that in the area of the sole tip on the tread of an additional sole plate made of steel or a steel coating of the soleplate there is no annoying temperature drop when the sole tip through Iron heat is removed. This should lead to better, faster and more uniform ironing results when using the iron. The advantages of the coated or with a covering or an additional soleplate of the iron tread should be retained.
Diese Aufgabe wird durch die Ausbildung des elektrisch beheizten Dampfbügeleisens gemäß dem kennzeichnenden Teil des Anspruchs 1 dadurch gelöst, daß die Bügelsohle im Bereich der Sohlenspitze eine Verdickung aus gut wärmeleitendem und gut wärmespeicherndem Material aufweist. Dieses Material ist gemäß Anspruch 5 Aluminium, aus dem auch die Bügelsohle besteht. Eine Beschichtung dieser Bügelsohle mit Stahl, also einem Material von gegenüber Aluminium verhältnismäßig schlechter Wärmeleitfähigkeit, bzw. die zusätzliche Sohlen- platte aus Stahl verursacht keinen unerwünscht großen Temperaturabfall im Sohlenspitzebereich beim Bügeln, weil die durch die geringe Wärmeleitfähigkeit des Stahls verzögerte Wärmeübertragung zwischen der Heizung des Bügeleisens und dem Bügelgut durch die gut wärmeleitende und gut wärmespeichernde verdickte Sohlenspitze ausgeglichen ist. Durch die Verdickung aus gut wärmeleitendem und gut wärmespeicherndem Material der Bügelsohle im Bereich ihrer Sohlenspitze wird eine rasche Wärmenachlieferung zur Sohlenspitze gewährleistet, womit sogar eine im zeitlichen Durchschnitt höhere Temperatur im Bereich der Sohlenspitze als in dem übrigen Bereich der Bügelsohle erreicht wird. Dies ist bei dem Dampfbügeleisen wegen des Wärmeentzugs durch verdampfendes Wasser wichtig. Hierzu ist die Verdickung mit zwei Schenkeln, also annähernd V-förmig in der Draufsicht betrachtet ausgeformt, wobei die Schenkel einen Dampferzeuger und speziell ein Dampflabyrinth auf der Oberseite der Bügelsohle zumindest teilweise umgreifen, welcher der Bügelsohle verhältnismäßig viel Wärme entzieht und somit erheblich zur Abkühlung eines Teilbereichs der Bügelsohle beiträgt.This object is achieved by the formation of the electrically heated steam iron according to the characterizing part of claim 1 in that the soleplate in the area of the sole tip has a thickening of good heat-conducting and good heat-storing material. This material is according to claim 5 aluminum, of which the soleplate is also made. A coating of this soleplate with steel, that is to say a material which has a relatively poor thermal conductivity compared to aluminum, or the additional sole plate made of steel does not cause an undesirably large drop in temperature in the tip area of the soleplate when ironing, because the heat transfer between the heating of the heating element which is delayed due to the low thermal conductivity of the steel Iron and the ironing good is balanced by the good heat-conducting and heat-storing thickened sole tip. The thickening of the heat-insulating and good heat-storing material of the soleplate in the area of the sole tip ensures rapid heat delivery to the sole tip, which means that the temperature in the area of the sole tip is higher on average than in the rest of the area of the soleplate. This is important for the steam iron because of the heat removal by evaporating water. For this purpose, the thickening is formed with two legs, i.e. approximately V-shaped when viewed in plan view, the legs at least partially encompassing a steam generator and especially a steam labyrinth on the top of the soleplate, which removes a relatively large amount of heat from the soleplate and thus considerably cools one down Part of the soleplate contributes.
Varianten und vorteilhafte Ausgestaltungen der Erfindung sindVariants and advantageous embodiments of the invention are
Gegenstand der Ansprüche 2 bis 7.Subject matter of claims 2 to 7.
Mit der in Anspruch 2 angegebenen bugähnlichen Gestaltung der Verdickung wird der gewünschte Temperaturverlauf in der Sohlenspitze erzielt, der zu dem übrigen Bereich der Sohlenfläche bzw. der Lauffläche gleichmäßig übergeht. Diese Formgebung behindert auch das Bügeln mit der Sohlenspitze nicht.With the bow-like configuration of the thickening specified in claim 2, the desired temperature profile is achieved in the sole tip, which passes smoothly to the remaining area of the sole surface or the tread. This shape does not hinder ironing with the sole tip.
Gemäß Anspruch 3 ist in einer Variante die Verdickung einstückig aus der Bügelsohle ausgeformt, wozu gehört, daß die Verdickung aus dem gleichen Material wie die Bügelsohle be- steht, insbesondere aus Aluminium. Ein Wärmeübertragungsproblem zwischen Bügelsohle und Verdickung kann nicht auftreten.According to claim 3, in a variant, the thickening is formed in one piece from the soleplate, which includes that the thickening is made of the same material as the soleplate. stands, especially made of aluminum. A heat transfer problem between the soleplate and the thickening cannot occur.
In der Variante nach Anspruch 4 ist hingegen die Verdickung als separater Formkörper ausgebildet, der auf der Bügelsohle gut wärmeleitend befestigt ist, beispielsweise angeschraubt ist. Diese Variante hat den Vorteil, daß der Formkörper getrennt zu üblichen Bügelsohlen passend gefertigt werden kann, daß also nicht unbedingt eine spezielle Bügelsohlenfertigung eingerichtet werden muß.In the variant according to claim 4, on the other hand, the thickening is designed as a separate molded body which is fastened to the soleplate with good heat conduction, for example screwed on. This variant has the advantage that the molded body can be manufactured separately to match the usual soleplate, so that it is not absolutely necessary to set up a special soleplate production.
Damit die von dem Heizkörper erzeugte Wärme gut in die Verdickung übertragen wird, sind die Merkmale gemäß den Ansprüchen 6 und 7 vorgesehen.So that the heat generated by the radiator is transferred well into the thickening, the features according to claims 6 and 7 are provided.
Aus der nachfolgenden Beschreibung können weitere Merkmale und Vorteile der Erfindung hervorgehen.Further features and advantages of the invention may emerge from the following description.
Ein Ausführungsbeispiel der Erfindung wird im folgenden an- hand einer Zeichnung mit drei Figuren beschrieben. Es zeigt:An embodiment of the invention is described below with reference to a drawing with three figures. It shows:
Fig. 1 eine elektrisches Dampfbügeleisen in einer schaubildlichen Ansicht von seitlich vorne;Figure 1 is an electric steam iron in a perspective view from the side front.
Fig. 2 eine Seitenansicht des Dampfbügeleisens gemäß Fig. 1 im Bereich der Bügeleisenspitze geschnitten undFig. 2 is a side view of the steam iron shown in FIG. 1 cut in the area of the iron tip and
Fig. 3 eine Draufsicht auf das Dampfbügeleisen gemäß den Fig. 1 und 2, ebenfalls im Bereich der Bügeleisenspitze geschnitten.Fig. 3 is a plan view of the steam iron according to FIGS. 1 and 2, also cut in the area of the iron tip.
In der Zeichnung ist mit 1 ein Bügeleisenkörper bezeichnet, der ein unteres Gehäuse und einen über diesem angeordneten Wassertank sowie einen Handgriff umfaßt. Unter dem Gehäuse des Bügeleisenkörpers befindet sich eine Bügelsohle 2 aus Aluminium. Zwischen dem aus Kunststoff bestehenden Gehäuse des Bügeleisenkörpers und der Bügelsohle 2 besteht ein Luftspalt, der im Bereich der Sohlenspitze bezeichnet ist. In die Bügelsohle ist ein Heizkörper 3 eingelassen, von dem in Fig. 2 ein Querschnitt erkennbar ist. Über dem Heizkörper 3 befinden sich eine Dampfkammer 4, an die beidseitig als Schenkel angrenzend Dampfstoßkanäle 5 und 6 angeordnet sind. Im wesentlichen parallel dazu verläuft nach vorne, d.h. zur Bügeleisenspitze hin ein Dampflabyrinth 7, in dessen Boden Dampflöcher 8, 9, 10 durch die Bügelsohle sowie durch eine auf der Unterseite der Bügelsohle angebrachte zusätzliche Sohlenplatte aus Stahl 11 hindurchreichen.In the drawing, 1 denotes an iron body, which comprises a lower housing and a water tank arranged above it, and a handle. There is an iron soleplate 2 made of aluminum under the housing of the iron body. There is an air gap between the housing of the iron body made of plastic and the soleplate 2, which is designated in the area of the sole tip. In the A soleplate 3 is embedded in the soleplate, a cross section of which can be seen in FIG. 2. Above the radiator 3 there is a steam chamber 4, to which steam boost channels 5 and 6 are arranged on both sides as legs. Essentially parallel to the front, ie towards the tip of the iron, is a steam maze 7, in the bottom of which steam holes 8, 9, 10 extend through the soleplate and through an additional sole plate made of steel 11 attached to the underside of the soleplate.
Aus Fig. 2 kann ersehen werden, daß die Dampfkammer 4 und das Dampflabyrinth 7 durch einen Dampfkanaldeckel 12 oben abgedeckt sind, der auch über den Dampfstoßkanälen 5 und 6 liegt. Durch den Dampfkanaldeckel 12 reicht ein Wasserventil 13 von dem nicht bezeichneten Wassertank in die Dampfkammer 4.From Fig. 2 it can be seen that the steam chamber 4 and the steam labyrinth 7 are covered at the top by a steam duct cover 12 which also lies above the steam boost ducts 5 and 6. A water valve 13 extends through the steam duct cover 12 from the water tank (not designated) into the steam chamber 4.
In dem Bereich der Sohlenspitze weist die Bügelsohle 2 eine bug- oder pflugförmige Verdickung 14 auf, die in der Draufsicht gemäß Fig. 3 mit zwei nicht bezeichneten Schenkeln einen Teil des Dampflabyrinths 7 sowie der Dampfkammer 4 umfaßt. Die Verdickung besteht aus dem gleichen gut wärmeleitendem Material, welches auch eine verhältnismäßig hohe Wärmekapazität aufweist wie die Bugelsohle, nämlich aus Aluminium. Infolge ihrer Formgebung und Anordnung bewirkt die Ver- dickung an der Bügelsohlenspitze nicht nur, daß diese im zeitlichen Durchschnitt eine höhere Temperatur als ohne solche Verdickung aufweist, sondern sie gewährleistet auch die gewünschte Temperatur der angrenzenden dampferzeugenden bzw. -leitenden Elemente. Zum Erzielen des gewünschten Temperatur- Verlaufs der Bugelsohlenspitze, die außerdem eine zum Bügeln geeignete Formgebung aufweisen soll, nimmt die Stärke der Verdickung von der Bugelsohlenspitze und einer Außenkante 16 ausgehend zunächst rasch zu, um nach hinten allmählich zu der Bügelsohle 2 hin abzufallen, wie im einzelnen aus den Fig. 1 und 2 ersichtlich. Um das Gehäuse des Bügeleisenkörpers 1 gegenüber der erhöhten Temperatur an der Verdickung 14 der Bugelsohlenspitze etwas abzuschirmen, befindet sich zwischen der Oberseite der Verdickung und dem Gehäuse der Luftspalt 15, der somit höher und zurückversetzt liegt im Vergleich zu dem üblichen Luftspalt zwischen der Oberseite einer Bügelsohle und einem aus Kunststoff bestehenden Gehäuse. In the area of the sole tip, the soleplate 2 has a bow-shaped or plow-shaped thickening 14 which, in the plan view according to FIG. 3, comprises part of the steam labyrinth 7 and the steam chamber 4 with two legs which are not designated. The thickening consists of the same good heat-conducting material, which also has a relatively high heat capacity as the soleplate, namely aluminum. As a result of its shape and arrangement, the thickening on the soleplate tip not only causes it to have a higher temperature on average than without such thickening, but it also ensures the desired temperature of the adjacent steam-generating or -conducting elements. In order to achieve the desired temperature profile of the tip of the sole, which should also have a shape suitable for ironing, the thickness of the thickening from the tip of the sole and an outer edge 16 initially increases rapidly in order to gradually fall towards the rear of the soleplate 2, as in FIG individual from FIGS. 1 and 2 can be seen. In order to shield the casing of the iron body 1 somewhat from the increased temperature at the thickening 14 of the tip of the sole, there is between the top of the thickening and the housing of the air gap 15, which is thus higher and set back compared to the usual air gap between the top of an iron soleplate and a housing made of plastic.
