Description

Die Erfindung betrifft ein Dampfbügeleisen für den häuslichen Gebrauch nach dem Oberbegriff des Patentanspruchs 1, mit einer Dampferzeugungseinrichtung zum Erzeugen von Dampf, die eine Dampfkammer und eine Heizeinrichtung hat, mit einem Wassertank zum Bereitstellen von Kaltwasser für die Dampferzeugungseinrichtung und mit einer Pumpe zum Fördern von Kaltwasser in die Dampfkammer.The invention relates to a steam iron for domestic use according to the preamble of claim 1, comprising a steam generating means for generating steam, having a steam chamber and a heater, with a water tank for providing cold water for the steam generating means and with a pump for conveying cold water in the steam chamber.

Herkömmliche Dampfbügeleisen ermöglichen nicht nur in einer horizontalen Arbeitslage einen Dampfstoß, sondern ebenfalls in einer von der horizontalen Arbeitslage abweichenden Alternativlage. Die Alternativlage kann beispielsweise eine vertikale Arbeitslage zum Bügeln von hängenden Gardinen sein. Ebenso kann die Alternativlage eine vertikale Ruhelage des Dampfbügeleisens sein. Während ein Dampfstoß in der vertikalen Arbeitslage beim beispielhaften Bügeln von Gardinen grundsätzlich zur Steigerung der Bügelqualität begrüßt wird, kann ein Dampfstoß in der vertikalen Ruhelage insbesondere eine Kühlfunktion zur Kühlung der Bügeleisensohle erfüllen, wie beispielsweise in der WO 96/23299 A1 beschrieben. Soll jedoch bspw. ein von einer Dampfstufe eines Bügelprogramms automatisch vorgegebener Dampfstoß außerhalb der horizontalen Arbeitslage verhindert werden, ist eine aufwendige interne Kaltwasserführung notwendig, um eine Zuführung von Kaltwasser aus einem Wassertank in eine Dampfkammer zu verhindern. Bekannte Kaltwasserführungen sehen vor, das Kaltwasser in einer von der horizontalen Arbeitslage abweichenden Alternativlage an der Dampfkammer vorbei im Kreis nicht zu führen, sodass aus dem Wassertank entnommenes Kaltwasser zurück in den Wassertank geführt wird.Conventional steam irons allow not only in a horizontal working position a shot of steam, but also in a deviating from the horizontal working position alternative situation. The alternative situation can be, for example, a vertical working position for ironing hanging curtains. Likewise, the alternative layer may be a vertical rest position of the steam iron. While a shot of steam in the vertical working position in the exemplary ironing curtains is basically welcomed to increase the ironing quality, a shot of steam in the vertical rest position can in particular fulfill a cooling function for cooling the soleplate, such as in the WO 96/23299 A1 described. However, if, for example, one of a steam stage of a ironing program automatically predetermined steam beyond the horizontal working position to be prevented, a complex internal cold water supply is necessary to prevent a supply of cold water from a water tank into a steam chamber. Known cold water ducts provide that the cold water in a deviating from the horizontal working position alternative situation to the steam chamber over in a circle not to lead, so taken from the water tank cold water is fed back into the water tank.

Aufgabe der Erfindung ist es, ein Dampfbügeleisen für den häuslichen Gebrauch zu schaffen, das bei einem einfachen vorrichtungstechnischen Aufwand einen Dampfstoß in einer von einer horizontalen Arbeitsposition abweichenden Alternativlage verhindert.The object of the invention is to provide a steam iron for domestic use, which prevents in a simple device engineering effort a shot of steam in a deviating from a horizontal working position alternative situation.

Diese Aufgabe wird gelöst durch ein Dampfbügeleisen mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der abhängigen Ansprüche.This object is achieved by a steam iron with the features of claim 1. Advantageous embodiments and developments, which individually or in Combination can be used together are the subject of the dependent claims.

Ein erfindungsgemäßes Dampfbügeleisen für den häuslichen Gebrauch weist eine Dampferzeugungseinrichtung zum Erzeugen von Dampf, die eine Dampfkammer und eine Heizeinrichtung hat, einen Wassertank zum Bereitstellen von Kaltwasser für die Dampferzeugungseinrichtung und eine Pumpe zum Fördern von Kaltwasser in die Dampfkammer auf. Erfindungsgemäß hat das Dampfbügeleisen einen Lagesensor zum Bestimmen von Lagen des Dampfbügeleisens, wobei in einer von einer horizontalen Arbeitslage abweichenden Alternativlage die Pumpe deaktiviert ist.A domestic steam iron according to the present invention has a steam generating means for generating steam having a steam chamber and a heater, a water tank for supplying cold water to the steam generating means, and a pump for feeding cold water into the steam chamber. According to the invention, the steam iron has a position sensor for determining layers of the steam iron, the pump being deactivated in an alternative position deviating from a horizontal working position.

Durch die Deaktivierung ist die Pumpe daran gehindert, Wasser in die Dampfkammer zu fördern. Dabei wird sowohl ein Dampfstoß gemäß einer vom jeweiligen Bügelprogramm vorgebebenen automatischen Dampfstufe als auch gemäß einer vom Verbraucher manuell eingestellten Dampfstufe unabhängig von dem eingestellten Bügelprogramm unterbunden. Der Lagesensor ist ein wasserführungsfreies Bauteil und unterliegt somit keiner Verkalkung wie eine vorbeschriebene Kaltwasserkreislaufführung. Der Lagesensor lässt sich einfach in eine bestehende Geräteelektronik integrieren bzw. die Geräteelektronik lässt sich einfach zur Berücksichtigung des Lagesensors und der deaktivierbaren Pumpe modifizieren. Sonstige elektrische Funktionen bleiben bei der Deaktivierung der Pumpe aktiviert, so dass eine Sohlenheizung weiter bestromt bleibt und eine Abkühlung der Sohle verhindert wird.Deactivation prevents the pump from delivering water to the steam chamber. In this case, both a steam pulse is prevented regardless of the set ironing program according to a predetermined by the respective ironing program automatic steam level and according to a manually set by the consumer steam level. The position sensor is a water guidance free component and is therefore subject to no calcification as a prescribed cold water circulation guide. The position sensor can be easily integrated into an existing device electronics or the device electronics can be easily modified to take into account the position sensor and the deactivatable pump. Other electrical functions remain activated when deactivating the pump, so that a sole heating remains energized and a cooling of the sole is prevented.

Bei einem bevorzugten Ausführungsbeispiel ist der Lagesensor ein Kugelsensor mit einer Kugel, die sich in der horizontalen Arbeitslage in einer Öffnungsposition und in der Alternativlage in einer Schließstellung befindet. Ein derartiger Lagesensor ist insbesondere technisch einfach auszuführen, präzise, zuverlässig und wartungsarm.In a preferred embodiment, the position sensor is a ball sensor with a ball which is in an open position in the horizontal operating position and in a closed position in the alternative position. Such a position sensor is in particular technically simple to execute, precise, reliable and low maintenance.

Um zu verhindern, dass in einer horizontalen Arbeitslage beim Bügeln die Pumpe deaktiviert wird, ist ein Zeitnehmer zum Deaktivieren der Pumpe nach einer vorgegebenen Wartezeit vorgesehen, während der sich die Kugel in ihrer Schließposition befindet. Die Kugel könnte nämlich durch die horizontalen Bügelbewegungen zwischen ihrer Öffnungsposition und ihrer Schließposition hin und her bewegt werden, wodurch ohne die Berücksichtigung einer derartigen Wartezeit die Pumpe ständig deaktiviert und aktiviert werden würde, was das Bügeln wesentlich erschweren würde. Aufgrund der Berücksichtigung der Wartezeit wird jedoch ein derartiges Aktivieren und Deaktivieren in der horizontalen Arbeitsposition verhindert, wodurch ein qualitativ hochwertiges Bügelergebniserzielt werden kann.In order to prevent the pump from being deactivated in a horizontal working position during ironing, a timer is provided for deactivating the pump after a predetermined waiting time during which the ball is in its closed position. The ball could namely be moved back and forth by the horizontal ironing movements between its open position and its closed position, whereby the pump is constantly deactivated without taking into account such a waiting time and would be activated, which would make the ironing much more difficult. However, due to consideration of the waiting time, such activation and deactivation in the horizontal working position is prevented, whereby a high-quality ironing result can be achieved.

Es hat sich als vorteilhaft herausgestellt, wenn die Wartezeit ≥ 0,15 und ≤ 1 Sekunden ist.It has proven to be advantageous if the waiting time is ≥ 0.15 and ≤ 1 second.

Bevorzugterweise ist die Wartezeit ≥ 0,25 Sekunden und ≤ 0,7 Sekunden.Preferably, the waiting time is ≥ 0.25 seconds and ≤ 0.7 seconds.

Bei einem Ausführungsbeispiel erfasst der Zeitnehmer eine Zeit, während der sich die Kugel in ihrer Schließposition befindet, wobei sich das Dampfbügeleisen nach dem Überschreiten einer vorgegebenen Wartezeit ausschaltet. Hierdurch wird eine automatische Abschaltung bzw. automatische Ausschaltung des Dampfbügeleisens erreicht, sodass in einer vertikalen Ruhelage des Dampfbügeleisens stets eine Abschaltung erfolgt.In one embodiment, the timer detects a time during which the ball is in its closed position, wherein the steam iron switches off after exceeding a predetermined waiting time. As a result, an automatic shutdown or automatic shutdown of the steam iron is achieved so that always takes place in a vertical rest position of the steam iron a shutdown.

Um das Dampfbügeleisen auch dann abzuschalten, wenn es sich in einer horizontalen Arbeitsposition befindet, jedoch unbeaufsichtigt ist, kann der Zeitnehmer eine berührungsfreie Zeit eines Griffsensors erfassen, wobei sich das Dampfbügeleisen nach dem Überschreiten einer vorgegebenen berührungsfreien Wartezeit ausschaltet. Der Griffsensor ist bevorzugter weise eine kapazitiver Sensor, der Berührungen des Bügeleisengriffs durch eine Hand reagiert.To shut down the steam iron even when it is in a horizontal working position, but unattended, the timer can detect a non-contact time of a handle sensor, the steam iron turns off after exceeding a predetermined non-contact waiting time. The handle sensor is preferably a capacitive sensor that responds to touches of the iron handle by a hand.

Zur Reduzierung einer Komplexität des Zeitnehmers und dessen Steuer- und/oder Regelung, ist es vorteilhaft, wenn der Zeitnehmer jedes Mal wenn der Ball wieder in die Öffnungsposition (Arbeitslage des Dampfbügeleisens) und somit "resettet bzw. genullt" wird.To reduce a complexity of the timer and its control and / or regulation, it is advantageous if the timekeeper each time when the ball again in the open position (working position of the steam iron) and thus "reset or zeroed" is.

Um auch in einer vertikalen Arbeitslage, beispielsweise zum Bügeln von hängenden Gardinen, einen Dampfstoß erzeugen zu können, ist es vorteilhaft, wenn das Dampfbügeleisen ein manuelles Dampfstoßelement hat. Das Dampfstoßelement wirkt beispielsweise auf eine separate mechanische Pumpe, so dass keine aufwendige Regelung und/oder Steuerung notwendig ist, um bei Betätigung des Dampfstoßelementes die deaktivierte Pumpe zu umgehen.In order to produce a steam pulse in a vertical working position, for example for ironing hanging curtains, it is advantageous if the steam iron has a manual steam impingement element. The steam-impingement element acts, for example, on a separate mechanical pump, so that no elaborate control and / or control is necessary in order to bypass the deactivated pump when the steam-impingement element is actuated.

Die Erfindung eignet sich insbesondere zur Bereitstellung eines Dampfbügeleisens für den häuslichen Gebrauch, mit einer vorrichtungstechnisch einfachen und zuverlässigen Deaktivierung einer Pumpe außerhalb einer horizontalen Arbeitslage des Dampfbügeleisens.The invention is particularly suitable for providing a steam iron for domestic use, with a device-technically simple and reliable deactivation of a pump outside a horizontal working position of the steam iron.

Im Folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand einer stark vereinfachten schematischen Darstellung näher erläutert. Die einzige Figur 1 zeigt einen Längsschnitt durch ein Ausführungsbeispiel eines erfindungsgemäßen Dampfbügeleisens.In the following, a preferred embodiment of the invention is explained in more detail with reference to a greatly simplified schematic representation. The only FIG. 1 shows a longitudinal section through an embodiment of a steam iron according to the invention.

In Figur 1 ist ein Längsschnitt durch ein Ausführungsbeispiel eines erfindungsgemäßen Dampfbügeleisens 1 für den häuslichen Gebrauch in einer horizontalen Arbeitslage gezeigt. Das Dampfbügeleisens 1 hat ein Gehäuse 2 mit einem Handgriff 4 und eine Sohle 6. Die Sohle 6 ist beheizbar und mit nicht gezeigten Löchern zum Ausstoßen von Dampf versehen. In dem Gehäuse 2 ist eine Geräteelektronik zum Steuern und Regeln von Bügelprogrammen angeordnet, von der im Folgenden einzelne Elemente beziffert sind.In FIG. 1 is a longitudinal section through an embodiment of a steam iron according to the invention 1 for domestic use in a horizontal working position shown. The steam iron 1 has a housing 2 with a handle 4 and a sole 6. The sole 6 is heated and provided with holes not shown for ejecting steam. In the housing 2, a device electronics for controlling and regulating ironing programs is arranged, of which individual elements are numbered below.

Zur Dampferzeugung ist in dem Gehäuse 2 eine Dampferzeugungseinrichtung angeordnet, die eine Dampfkammer 8 und eine Heizeinrichtung 10 umfasst. Zum Bereitstellen von Kaltwasser für die Dampferzeugungseinrichtung hat das Dampfbügeleisen 1 einen Wassertank 12, der über eine Fluidleitung 14 mit der Dampfkammer 8 verbunden ist. In der Fluidleitung 14 ist eine Pumpe 16 zur bedarfsgerechten Kaltwasserzufuhr in die Dampfkammer 8 angeordnet.For steam generation, a steam generating device is arranged in the housing 2, which comprises a steam chamber 8 and a heating device 10. For providing cold water for the steam generating device, the steam iron 1 has a water tank 12, which is connected via a fluid line 14 to the steam chamber 8. In the fluid line 14, a pump 16 is arranged for demand-adequate cold water supply into the steam chamber 8.

Die Bestromung des Dampfbügeleisens 1 erfolgt über ein Stromkabel 18, das mit einer in dem Gehäuse 2 angeordneten Hauptschalteinheit 20 in elektrischer Verbindung steht. Beim Verbinden des Stromkabels 18 mit einem Hausnetz wird das Dampfbügeleisen 1 eingeschaltet und somit in einen Betriebszustand überführt, indem die Sohle 6 und die Heizeinrichtung 10 der Dampfkammer 8 gemäß einem eingestellten Bügelprogramm beheizt werden.The energization of the steam iron 1 via a power cable 18 which is in electrical communication with a housing 2 arranged in the main switching unit 20. When connecting the power cable 18 with a house network, the steam iron 1 is turned on and thus transferred to an operating state by the sole 6 and the heater 10 of the steam chamber 8 are heated according to a set ironing program.

Um das Dampfbügeleisen nach einer bestimmten Zeit in einem unbeaufsichtigten Zustand unabhängig von seiner Lage auszuschalten, ist im Griff 4 ein kapazitiver Sensor 22 angeordnet. Der im folgenden Griffsensor genannte kapazitive Sensor 22 registriert, ob der Griff 4 des Dampfbügeleisens von einer Hand umgriffen ist oder nicht. Um ein sofortiges Abschalten des Dampfbügeleisens 1 beim Loslassen des Griffes zu verhindern, wirkt der Griffsensor 22, wie durch die Linie 24 angedeutet, mit einem Zeitnehmer 26 der Gerätelektronik zusammen. Der Zeitnehmer 26 erfasst eine berührungsfreie Zeit des Griffsensors 22, so dass erst nach dem Überschreiten einer vorgegebenen berührungsfreien Wartezeit tGSA (Wartezeit des Griffsensors zum Abschalten des Dampfbügeleisens) das Dampfbügeleisen 1 automatisch abgeschaltet wird. Die automatische Abschaltung des Dampfbügeleisens 1 ist durch die Linie 28 zwischen dem Zeitnehmer 26 und der Hauptschalteinheit 20 dargestellt. "Abschalten" bedeutet dabei, dass das Dampfbügeleisen 1 vom Hausnetz getrennt wird und somit vollständig nicht mehr bestromt wird. Die automatische Abschaltung über den Griffsensor 22 ist sowohl in der horizontalen Arbeitslage des Dampfbügeleisens 1, als auch in einer von der horizontalen Arbeitslage abweichenden Alternativlage aktiviert und somit lageunabhängig. Eine Alternativlage ist zum Beispiel eine vertikale Ruhelage des Dampfbügeleisens 1 auf seinem Heck 30 oder ein Schrägstellung aus der horizontalen Arbeitslage beim Abstellen des Dampfbügeleisens 1 auf einer Basis.To turn off the steam iron after a certain time in an unattended state regardless of its location, a capacitive sensor 22 is arranged in the handle 4. The capacitive sensor 22 mentioned in the following grip sensor registers whether the handle 4 of the steam iron is gripped by a hand or not. In order to prevent an immediate shutdown of the steam iron 1 when releasing the handle, the handle sensor 22, as indicated by the line 24, cooperates with a timer 26 of the device electronics. The timer 26 detects a non-contact time of the handle sensor 22, so that only after exceeding a predetermined non-contact waiting time t GSA (waiting time of the handle sensor for switching off the steam iron) the steam iron 1 is automatically switched off. The automatic shutdown of the steam iron 1 is represented by the line 28 between the timer 26 and the main switching unit 20. "Shutdown" means that the steam iron 1 is disconnected from the house network and thus completely no longer energized. The automatic shutdown via the handle sensor 22 is activated both in the horizontal working position of the steam iron 1, as well as in an alternative to the horizontal working position alternative situation and thus independent of position. An alternative situation is, for example, a vertical rest position of the steam iron 1 on its tail 30 or an inclination from the horizontal working position when turning off the steam iron 1 on a base.

Die Geräteelektronik ist derart ausgeführt, dass in der horizontalen Arbeitslage eine Pumpe zum Erzeugen eines Dampfstoßes aktiviert ist, während in einer Alternativlage außerhalb der horizontalen Arbeitslage die Pumpe automatisch deaktiviert ist. Dabei wird sowohl ein Dampfstoß gemäß einer vom jeweiligen Bügelprogramm vorgebebenen automatischen Dampfstufe als auch gemäß einer vom Verbraucher manuell eingestellten Dampfstufe unabhängig von dem eingestellten Bügelprogramm unterbunden. Hierzu hat das Dampfbügeleisen 1 bzw. die Geräteelektronik einen Lagesensor 32. Der Lagesensor 32 erfasst Lagen des Dampfbügeleisens 1 und ist beispielsweise ein Kugelsensor mit einer Kugel, die sich in der horizontalen Arbeitslage des Dampfbügeleisens 1 in einer Öffnungsposition und in einer Alternativlage in einer Schließposition befindet.The device electronics is designed such that in the horizontal working position, a pump is activated to generate a steam pulse, while in an alternative position outside the horizontal working position, the pump is automatically deactivated. In this case, both a steam pulse is prevented regardless of the set ironing program according to a predetermined by the respective ironing program automatic steam level and according to a manually set by the consumer steam level. The position sensor 32 detects positions of the steam iron 1 and is for example a ball sensor with a ball which is in the horizontal operating position of the steam iron 1 in an open position and in an alternative position in a closed position ,

Da jedoch durch die Bügelbewegungen des Dampfbügeleisens 1 beim Bügeln in der horizontalen Arbeitslage die Kugel ständig zwischen ihrer Öffnungsposition und Schließposition wechselt bzw. wechseln kann, wirkt der Lagesensor 32, wie durch die Linie 34 angedeutet, mit dem Zeitnehmer 26 zusammen. Der Zeitnehmer 26 ist zum Deaktivieren der Pumpe erst nach einer vorgegebenen Wartezeit tLsD (Wartezeit des Lagesensors zum Deaktivieren der Pumpe) vorgesehen, während der sich die Kugel in ihrer Schließposition befindet. Somit wird verhindert, dass bei jeder Positionsverschiebung der Kugel die Pumpe sofort deaktiviert wird, wodurch das Bügeln in der horizontalen Arbeitslage wesentlich erschwert werden würde. Die Geräteelektronik registriert also, ob sich die Kugel aufgrund von Bügelbewegungen in einer horizontalen Arbeitslage seine Schließposition einnimmt oder aufgrund eines Abstellens des Dampfbügeleisens 1 in einer vertikalen Ruhelage. Die automatische Deaktivierung der Pumpe nach der Wartezeit tLSD ist durch die Linie 36 zwischen dem Zeitnehmer 26 und der Pumpe 16 angedeutet.However, since the ball constantly changes between its open position and closed position by the ironing movements of the steam iron 1 when ironing in the horizontal position, the position sensor 32 acts as through the Line 34 indicated, with the timer 26 together. The timer 26 is provided for deactivating the pump only after a predetermined waiting time t LsD (waiting time of the position sensor for deactivating the pump), during which the ball is in its closed position. This prevents that the pump is deactivated immediately at each position shift of the ball, whereby the ironing would be much more difficult in the horizontal working position. The device electronics registered so whether the ball assumes its closed position due to ironing movements in a horizontal working position or due to a shutdown of the steam iron 1 in a vertical rest position. The automatic deactivation of the pump after the waiting time t LSD is indicated by the line 36 between the timer 26 and the pump 16.

Der Zeitnehmer 26 nimmt die Zeit, sobald sich die Kugel in ihrer Schließposition befindet. Wenn, wie beim Bügeln aufgrund der horizontalen Bewegung des Dampfbügeleisens 1, die Kugel regelmäßig zwischen ihrer Öffnungsposition und ihrer Schließposition hin und her bewegt wird, die Wartezeit tLSD jedoch nicht überschritten wird, wird die Pumpe nicht deaktiviert. Die Wartezeit tLSD bewegt sich beispielsweise in dem Zeitintervall 0,15s ≤ tLSD ≤ 1s. Bevorzugt erweise bewegt sich die Wartezeit in dem folgenden Zeitintervall: 0,25s ≤ tLSD ≤ 0,7 s. Mittels des Zeitnehmers 26 werden minimale Unterbrechungen während des Bügels in der horizontalen Arbeitslage verhindert, wenn aufgrund von Bügelbewegungen die Kugel für kurze Zeit aus ihrer Öffnungsposition in ihre Schließposition bewegt wird, woraufhin die Pumpe eigentlich deaktiviert wird. Wenn nun aber die Kugel rechtzeitig zurück in ihre Öffnungsposition geht, wird die Pumpe nicht deaktiviert.The timer 26 takes the time when the ball is in its closed position. If, as in ironing due to the horizontal movement of the steam iron 1, the ball is regularly moved back and forth between its open position and its closed position, but the waiting time t LSD is not exceeded, the pump is not deactivated. The waiting time t LSD moves, for example, in the time interval 0.15 s ≦ t LSD ≦ 1 s. Preferably, the waiting time moves in the following time interval: 0.25 s ≦ t LSD ≦ 0.7 s. By means of the timer 26 minimal interruptions are prevented during the bracket in the horizontal working position when due to ironing movements, the ball is moved from its open position to its closed position for a short time, after which the pump is actually deactivated. But if the ball goes back to its opening position in time, the pump is not deactivated.

Wie durch die Linie 38 zwischen dem Zeitnehmer 24 und der Hauptschalteinheit 20 angedeutet, kann der Zeitnehmer 26 alternativ oder zusätzlich zum Griffsensor 22 eine weitere Zeit erfassen, während der sich die Kugel in ihrer Schließposition befindet, wobei sich das Dampfbügeleisen 1 nach dem Überschreiten einer vorgegebenen Wartezeit tLSA (Wartezeit Lagesensors zum Abschalten des Dampfbügeleisens) ausschaltet. Hierdurch wird eine automatische Abschaltung des Dampfbügeleisens 1 basierend auf dem Lagesensor 32 vorgenommen. Bevorzugter weise gilt tLSD < tGSA ≤ tLSA.As indicated by the line 38 between the timer 24 and the main switching unit 20, the timer 26 may alternatively or additionally to the handle sensor 22 detect a further time during which the ball is in its closed position, wherein the steam iron 1 after exceeding a predetermined Waiting time t LSA (waiting time position sensor for switching off the steam iron) switches off. As a result, an automatic shutdown of the steam iron 1 is made based on the position sensor 32. Preferably, t LSD <t GSA ≦ t LSA .

Der Zeitnehmer 26 wird nach jeder Rückführung des Dampfbügeleisens 1 in seine Arbeitslage oder nach jedem Abschalten des Dampfbügeleisens 1 in seinen Ausgangszustand überführt und somit genullt. Hierdurch beginnen eine Zeitmessung stets bei dem Wert t = 0s.The timer 26 is after each return of the steam iron 1 in its working position or after each shutdown of the steam iron 1 in his Initial state transferred and thus zeroed. As a result, a time measurement always starts at the value t = 0s.

Um einen manuellen Dampfstoß in einer Alternativlage wie zum Beispiel beim Bügel von hängenden Gardinen oder aufgehängten Kleidungsstücken zu erreichen, hat das Dampfbügeleisen 1 ein manuelles Dampfstoßelement 40. Das manuelle Dampfstoßelement 40 wirkt auf eine nicht gezeigte mechanische Pumpe, mittels der in einer vertikalen Arbeitslage ein manueller Dampfstoß erzeugt werden kann. Es ist unabhängig von der vorbeschriebenen Pumpe, wie durch die Linie 42 zum Wassertank 12 und durch die Linie 44 zur Dampfkammer 8 skizziert. Das Dampfstoßelement 40 ist beispielsweise ein in einer Gehäuseöffnung geführter Druckknopf. Selbstverständlich kann auch in einer horizontalen oder in einer sonstigen Arbeitslage ein manueller Dampfstoß durch Betätigen des Dampfstoßelements 40 erzeugt werden.To achieve a manual steam boost in an alternative position such as hanging curtains or hanging garments, the steam iron 1 has a manual steam impingement element 40. The manual steam impingement element 40 acts on a mechanical pump, not shown, by means of a manual one in a vertical working position Steam can be generated. It is independent of the pump described above, as sketched by the line 42 to the water tank 12 and by the line 44 to the steam chamber 8. The steam impingement element 40 is, for example, a push button guided in a housing opening. Of course, even in a horizontal or other working position, a manual steam burst can be generated by actuating the steam blast element 40.
