Description

Die Erfindung betrifft eine Dampfvorrichtung für eine ein Handgerät umfassende Bügeleinrichtung, eine Bügeleinrichtung mit einer Dampfvorrichtung und ein Verfahren zum Betreiben der Dampfeinrichtung.The invention relates to a steam device for an ironing device comprising a hand-held appliance, an ironing device with a steam device and a method for operating the steam device.

Bei der Dampferzeugung für Bügelsysteme ist aus Kundensicht häufig neben einer festen Dampfmenge auch ein beispielsweise kurzfristig stärkerer Dampfstoß für Problemstellen oder dicke Textilien wünschenswert. Die maximale Dampfmenge ist dabei ein wesentliches Leistungsmerkmal. Die im Mittel verfügbare Verdampfungsleistung ist durch die elektrische Anschlussleistung für alle Hersteller gleichermaßen begrenzt. Eine unterschiedliche Effizienz der verschiedenen Heizsysteme hat beispielsweise nur bedingten Einfluss auf die gemittelte Dampfmenge. Abweichungen bei einer Dauerdampfleistung sind also zu einem großen Teil auf unterschiedlich effektiv durchgeführte Anpassungen des Systems an das genormte Messverfahren zurückzuführen. Auch wenn die meisten Kunden sich eine besonders hohe Leistung des Geräts wünschen, ist ein oft genannter Kundenwunsch dennoch, dass das Bügelsystem eine Energiesparfunktion aufweist, in der messbar weniger elektrische Energie aufgenommen wird als im Regelbetrieb. Dies wird allgemein als ECO-Funktion bezeichnet.When it comes to generating steam for ironing systems, customers often want not only a fixed amount of steam but also, for example, a short-term stronger boost of steam for problem areas or thick textiles. The maximum amount of steam is an essential performance feature. The average available evaporation capacity is equally limited by the electrical connection load for all manufacturers. A different efficiency of the various heating systems, for example, only has a limited influence on the average amount of steam. Deviations in a continuous steam output are therefore largely due to different effective adjustments of the system to the standardized measurement method. Even if most customers want the device to have a particularly high performance, one customer request that is often mentioned is that the ironing system has an energy-saving function, in which measurably less electrical energy is consumed than in normal operation. This is commonly referred to as the ECO function.

Das Dokument CN 207 295 290 U beschreibt ein energiesparendes Bügelgerät mit einem Regler zur Regelung des Temperaturbereiches eines Heizgerätes und mit zwei Heizelementen.The document CN 207 295 290 U describes an energy-saving ironing device with a controller for controlling the temperature range of a heating device and with two heating elements.

Die Erfindung stellt sich die Aufgabe, eine Dampfvorrichtung für eine ein Handgerät umfassende Bügeleinrichtung, eine Bügeleinrichtung mit einer Dampfvorrichtung sowie ein Verfahren zum Betreiben der Dampfeinrichtung zu schaffen.The object of the invention is to create a steam device for an ironing device comprising a hand-held appliance, an ironing device with a steam device and a method for operating the steam device.

Erfindungsgemäß wird diese Aufgabe durch eine verbesserte Dampfvorrichtung für eine ein Handgerät umfassende Bügeleinrichtung, eine verbesserte Bügeleinrichtung mit einer Dampfvorrichtung sowie durch ein Verfahren zum Betreiben der Dampfeinrichtung mit den Merkmalen der Hauptansprüche gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this object is achieved by an improved steam device for an ironing device comprising a hand-held appliance, an improved ironing device with a steam device and by a method for operating the steam device with the features of the main claims. Advantageous refinements and developments of the invention result from the following dependent claims.

Die mit der Erfindung erreichbaren Vorteile bestehen neben einem Erreichen einer messbar höheren Dampfmenge bei einem Beibehalten einer Geräteleistung.The advantages that can be achieved with the invention consist not only in achieving a measurably higher amount of steam while maintaining the device performance.

Es wird daher eine Dampfvorrichtung für eine ein Handgerät umfassende Bügeleinrichtung vorgestellt. Die Dampfvorrichtung weist dabei ein erstes Heizelement, das ausgebildet ist, um eine zumindest teilweise Flüssigkeit zu verdampfen und als Dampf bereitzustellen, und eine Pumpe auf, die ausgebildet ist, um die Flüssigkeit zu dem ersten Heizelement zu fördern. Weiterhin weist die Dampfvorrichtung ein zweites Heizelement, das ausgebildet ist, um den von dem ersten Heizelement bereitgestellten Dampf weiter zu erhitzen und als weiter erhitzen Dampf an das Handgerät bereitzustellen, und ein Abzweigelement auf, das eine einem Normalbetriebszustand der Bügeleinrichtung zugeordnete Normalstellung und eine einem Boostzustand der Bügeleinrichtung zugeordnete Booststellung aufweist. Dabei ist das Abzweigelement ausgebildet, um den Dampf in der Normalstellung an das Handgerät bereitzustellen und in der Booststellung zu dem zweiten Heizelement zu leiten.A steam device for an ironing device comprising a hand-held appliance is therefore presented. In this case, the steam device has a first heating element, which is designed to evaporate an at least partial liquid and provide it as steam, and a pump, which is designed to convey the liquid to the first heating element. Furthermore, the steam device has a second heating element, which is designed to to further heat steam provided by the first heating element and to provide further heated steam to the hand-held device, and a branching element which has a normal position associated with a normal operating state of the ironing device and a boost position associated with a boost state of the ironing device. In this case, the branching element is designed to provide the steam to the hand-held device in the normal position and to direct it to the second heating element in the boost position.

Die Bügeleinrichtung kann beispielsweise als ein handelsübliches Bügelsystem realisiert sein, das verwendet werden kann, um Gegenstände, vorzugsweise Textilien, zu glätten. Es kann sich dabei beispielsweise um ein Haushaltgerät handeln. Da eine große Anzahl von verschiedenartigen Textilien existiert und die Textilien demnach unterschiedlich empfindlich auf beispielsweise Wärme reagieren können, weist die Bügeleinrichtung beispielsweise eine Dampffunktion auf. Die Dampfvorrichtung ist ausgebildet, um die Dampffunktion zu ermöglichen. Die Dampfvorrichtung kann dabei beispielsweise stationäre und zusätzlich oder alternativ mobile, also in dem Handgerät angeordnete, Komponenten aufweisen. Das Handgerät kann beispielsweise als ein Bügeleisen ausgeformt sein. Das erste Heizelement und zusätzlich oder alternativ das zweite Heizelement kann beispielsweise als ein Energiespeicher realisiert sein, um vorteilhafterweise möglichst lange die Energie zu speichern. Die Flüssigkeit kann beispielsweise Wasser sein, das in verdampftem Zustand zu Wasserdampf wird. Je nach Pumpleistung kann die zu dem ersten Heizelement gepumpte Flüssigkeit vollständig oder nur teilweise verdampft werden. Wenn die Flüssigkeit nur teilweise verdampft wird, kann durch eine entsprechende Stellung des Abzweigelements eine Nachverdampfung in dem zweiten Heizelement durchgeführt werden. Der Normalbetriebszustand der Bügeleinrichtung kann von einem Nutzer ausgewählt werden oder standardmäßig voreingestellt sein. Im Normalbetriebszustand kann ausschließlich das erste Heizelement zur Dampferzeugung genutzt werden. Der Boostzustand der Bügeleinrichtung kann von einem Nutzer ausgewählt werden. Im Boostzustand kann zusätzlich zu dem ersten Heizelement auch das zweit Heizelement zur Dampferzeugung genutzt werden. Dadurch kann die erzeugbare Dampfmenge erhöht werden.The ironing device can be implemented, for example, as a commercially available ironing system that can be used to smooth objects, preferably textiles. This can be a household appliance, for example. Since there are a large number of different types of textiles and the textiles can therefore react with different sensitivity to heat, for example, the ironing device has a steam function, for example. The steam device is designed to enable the steam function. The steam device can, for example, have stationary and additionally or alternatively mobile components, ie components arranged in the hand-held device. The hand-held device can be in the form of an iron, for example. The first heating element and additionally or alternatively the second heating element can be implemented, for example, as an energy storage device in order to advantageously store the energy for as long as possible. The liquid can be water, for example, which becomes water vapor in the vaporized state. Depending on the pump power, the liquid pumped to the first heating element can be completely or only partially vaporized. If the liquid is only partially evaporated, post-evaporation can be carried out in the second heating element by a corresponding position of the branching element. The normal operating state of the ironing device can be selected by a user or can be preset by default. In the normal operating state, only the first heating element can be used to generate steam. The boost state of the ironing device can be selected by a user. In the boost state, the second heating element can also be used to generate steam in addition to the first heating element. As a result, the amount of steam that can be generated can be increased.

Gemäß einer Ausführungsform können das erste Heizelement als erster Thermoblock und das zweite Heizelement als zweiter Thermoblock ausgeformt sein. Vorteilhafterweise kann dadurch die aufgebrachte Energie in dem jeweiligen Heizelement gespeichert und zum verdampfen von zugeführter Flüssigkeit verwendet werden. Zudem ist auf diese Weise eine abwechselnde Beheizung der beiden Heizelemente möglich, wobei das dann gerade nicht beheizte Heizelement aufgrund seiner Speicherfunktion immer noch zum Verdampfen von Flüssigkeit verwendet werden kann.According to one embodiment, the first heating element can be formed as a first thermal block and the second heating element can be formed as a second thermal block. Advantageously, the energy applied can thereby be stored in the respective heating element and used to vaporize supplied liquid. In addition, alternating heating of the two heating elements is possible in this way, in which case the heating element which is then not being heated can still be used for evaporating liquid due to its storage function.

Die Dampfvorrichtung kann eine Steuereinrichtung aufweisen, die ausgebildet ist, um die Pumpe, das erste Heizelement, das zweite Heizelement sowie das Abzweigelement anzusteuern. Die Steuereinrichtung kann beispielsweise als eine Platine in einem Steuergerät oder aber als Steuergerät realisiert sein, das optional ausgebildet ist, um auch weitere Funktionen der Dampfvorrichtung und zusätzlich oder alternativ der Bügeleinrichtung zu steuern. Die Steuervorrichtung kann ausgebildet sein, um Eingangssignale einzulesen und unter Verwendung der Eingangssignale Ausgangssignale zu bestimmen und bereitzustellen. Ein Eingangssignal kann beispielsweise ein über eine Eingangsschnittstelle der Steuervorrichtung einlesbares Sensorsignal darstellen. Ein Ausgangssignal kann ein Steuersignal oder ein Datensignal darstellen, das an einer Ausgangsschnittstelle der Steuervorrichtung bereitgestellt werden kann. Die Steuervorrichtung kann ausgebildet sein, um die Ausgangssignale unter Verwendung einer in Hardware oder Software umgesetzten Verarbeitungsvorschrift zu bestimmen. Beispielsweise kann die Steuervorrichtung dazu eine Logikschaltung, einen integrierten Schaltkreis oder ein Softwaremodul umfassen und beispielsweise als ein diskretes Bauelement realisiert sein oder von einem diskreten Bauelement umfasst sein.The steam device can have a control device which is designed to control the pump, the first heating element, the second heating element and the branching element. The control device can be implemented, for example, as a circuit board in a control device or as a control device that is optionally designed to also control other functions of the steam device and additionally or alternatively the ironing device. The control device can be designed to read in input signals and to determine and provide output signals using the input signals. An input signal can represent, for example, a sensor signal that can be read in via an input interface of the control device. An output signal can represent a control signal or a data signal, which can be provided at an output interface of the control device. The control device can be designed to determine the output signals using a processing specification implemented in hardware or software. For example, the control device can include a logic circuit, an integrated circuit or a software module for this purpose and can be implemented as a discrete component, for example, or be comprised by a discrete component.

Gemäß einer Ausführungsform kann die Steuereinrichtung ausgebildet sein, um das zweite Heizelement insbesondere nur dann zu beheizen, wenn das erste Heizelement eine Solltemperatur aufweist. Vorteilhafterweise kann die Steuereinrichtung beispielsweise Signale wie ein Temperatursignal einzulesen und zusätzlich oder alternativ auszuwerten. Die Solltemperatur kann dabei vorbestimmt sein und in einer Speichereinheit hinterlegt sein. Auf diese Weise kann die maximal zum Beheizen der Heizelemente verwendete elektrische Energie auf einen vorgegebenen Maximalwert begrenzt werden.According to one embodiment, the control device can be designed to heat the second heating element in particular only when the first heating element has a setpoint temperature. Advantageously, the control device can, for example, read in signals such as a temperature signal and evaluate them additionally or alternatively. The target temperature can be predetermined and stored in a storage unit. In this way, the maximum amount of electrical energy used to heat the heating elements can be limited to a predetermined maximum value.

Gemäß einer Ausführungsform kann die Steuereinrichtung weiterhin ausgebildet sein, um ein Anzeigesignal zum Anzeigen einer Boostbereitschaft der Bügeleinrichtung bereitzustellen, wenn das zweite Heizelement eine weitere Solltemperatur aufweist. Dadurch kann einem Nutzer mittels einer LED-Anzeige, wie beispielsweise einer blinkenden Lampe, signalisiert werden, dass eine Boostfunktion der Bügeleinrichtung bereit ist.According to one embodiment, the control device can also be designed to provide a display signal for displaying a boost readiness of the ironing device when the second heating element has a further setpoint temperature. As a result, a user can be signaled by means of an LED display, such as a flashing lamp, that a boost function of the ironing device is ready.

Die Steuereinrichtung kann gemäß einer Ausführungsform ausgebildet sein, um das Abzweigelement ansprechend auf eine Boostanforderung in die Booststellung zu überführen. Die Boostanforderung kann beispielsweise mittels einer Betätigung einer Taste durch den Nutzer ausgelöst werden.According to one embodiment, the control device can be designed to convert the branching element into the boost position in response to a boost request. The boost request can be triggered by the user pressing a button, for example.

Gemäß einer Ausführungsform kann die Steuereinrichtung ausgebildet sein, um das Abzweigelement in die Normalstellung zu überführen, wenn das zweite Heizelement eine Mindesttemperatur unterschreitet. In diesem Fall kann die Steuereinrichtung ferner ausgebildet sein, um eine Fördermenge der Pumpe zu reduzieren. Dadurch kann eine Ausgabe von unverdampfter Flüssigkeit vermieden werden.According to one embodiment, the control device can be designed to move the branching element into the normal position when the second heating element falls below a minimum temperature. In this case, the controller can also be designed to reduce a delivery rate of the pump. In this way, dispensing of unevaporated liquid can be avoided.

Die Steuereinrichtung kann weiterhin ausgebildet sein, um während des Normalbetriebszustands eine erste Fördermenge der Pumpe und während des Boostzustands eine zweite Fördermenge der Pumpe einzustellen, wobei die zweite Fördermenge größer als die erste Fördermenge ist. Vorteilhafterweise kann dadurch im Boostzustand insgesamt eine große Menge an Dampf ausgelassen werden, um vorteilhafterweise beispielsweise Problemstellen oder dicke Stellen von zu glättenden Textilien zufriedenstellend bearbeiten zu können.The control device can also be designed to set a first delivery rate of the pump during the normal operating state and a second delivery rate of the pump during the boost state, the second delivery rate being greater than the first delivery rate. Advantageously, a large amount of steam can thereby be let out in the boost state, in order advantageously to be able to process problem areas or thick areas of textiles to be smoothed satisfactorily, for example.

Ferner wird eine Bügeleinrichtung mit einer Dampfvorrichtung in einer der zuvor genannten Varianten, einem stationären Teil und dem Handgerät vorgestellt, wobei das Handgerät eine Mehrzahl von Austrittsöffnungen aufweist, die ausgebildet ist, um den von dem ersten Heizelement erzeugten und zusätzlich oder alternativ von dem zweiten Heizelement weiter erhitzten Dampf auszulassen.Furthermore, an ironing device with a steam device in one of the aforementioned variants, a stationary part and the hand-held device is presented, the hand-held device having a plurality of outlet openings which are designed to allow the outlet openings generated by the first heating element and additionally or alternatively by the second heating element release further heated steam.

Der stationäre Teil kann beispielsweise ein Bügelbrett, die Pumpe und einen Wassertank umfassen. Der stationäre Teil kann mit dem Handgerät koppelbar realisiert sein kann. Die Austrittsöffnungen an dem Handgerät können beispielsweise als Düsen in einer Sohle des Handgeräts ausgeformt sein. Durch die Düsen kann der Dampf ausgelassen werden.The stationary part can include, for example, an ironing board, the pump and a water tank. The stationary part can be implemented so that it can be coupled to the hand-held device. The outlet openings on the hand-held device can be formed, for example, as nozzles in a soleplate of the hand-held device. The steam can be released through the nozzles.

Gemäß einer Ausführungsform kann das Handgerät eine weitere Mehrzahl von Austrittsöffnungen aufweisen, die ausgebildet ist, um insbesondere nur den von dem zweiten Heizelement weiter erhitzten Dampf auszulassen. Vorteilhafterweise ist die weitere Mehrzahl von Austrittsöffnungen als Mehrzahl von Düsen realisierbar.According to one embodiment, the hand-held device can have a further plurality of outlet openings, which are designed in particular to let out only the steam further heated by the second heating element. Advantageously, the further plurality of outlet openings can be implemented as a plurality of nozzles.

Das erste Heizelement kann in dem stationären Teil der Bügeleinrichtung angeordnet sein und das zweite Heizelement sowie das Abzweigelement können im Handgerät angeordnet sein. Vorteilhafterweise kann dadurch ein Druckverlust und eine Dampfabkühlung während des Boostvorgangs reduziert werden.The first heating element can be arranged in the stationary part of the ironing device and the second heating element and the branching element can be arranged in the hand-held device. A pressure loss and vapor cooling during the boost process can advantageously be reduced as a result.

Gemäß einer Ausführungsform können das erste Heizelement, das zweite Heizelement und das Abzweigelement in dem stationären Teil der Bügeleinrichtung angeordnet sein. Vorteilhafterweise kann dadurch das Handgerät sehr kompakt ausgeformt werden.According to one embodiment, the first heating element, the second heating element and the branching element can be arranged in the stationary part of the ironing device. Advantageously, this allows the hand-held device to be made very compact.

Es wird außerdem ein Verfahren zum Betreiben einer Dampfvorrichtung in einer der zuvor genannten Varianten vorgestellt, wobei das Verfahren einen Schritt des Beheizens, einen Schritt des Pumpens, einen weiteren Schritt des Beheizens sowie einen Schritt des Einstellens umfasst. Im Schritt des Beheizens wird ein erstes Heizelement beheizt, das ausgebildet ist, um eine Flüssigkeit zumindest teilweise zu verdampfen und als Dampf bereitzustellen. Im Schritt des Pumpens wird die Flüssigkeit zu dem ersten Heizelement gepumpt. Im weiteren Schritt des Beheizens wird ein zweites Heizelement beheizt, das ausgebildet ist, um den Dampf weiter zu erhitzen und als weiter erhitzen Dampf an das Handgerät bereitzustellen. Im Schritt des Einstellens wird ein Abzweigelement in eine einem Normalbetriebszustand der Bügeleinrichtung zugeordnete Normalstellung und in eine einem Boostzustand der Bügeleinrichtung zugeordnete Booststellung eingestellt und der Dampf wird in der Normalstellung an das Handgerät bereitgestellt sowie in der Booststellung zu dem zweiten Heizelement geleitet.A method for operating a steam device in one of the previously mentioned variants is also presented, the method comprising a heating step, a pumping step, a further heating step and an adjustment step. In the heating step, a first heating element is heated, which is designed to at least partially evaporate a liquid and as a vapor to provide. In the pumping step, the liquid is pumped to the first heating element. In the further heating step, a second heating element is heated, which is designed to further heat the steam and to provide further heated steam to the hand-held device. In the setting step, a branching element is set into a normal position assigned to a normal operating state of the ironing device and into a boost position assigned to a boosted state of the ironing device, and the steam is made available to the hand-held appliance in the normal position and to the second heating element in the boosted position.

Das Verfahren kann vorteilhafterweise von einer Steuereinrichtung durchgeführt werden, wie sie in der Dampfvorrichtung verbaut ist. Vorteilhafterweise kann durch das Verfahren die Dampfvorrichtung energiesparend verwendet werden.The method can advantageously be carried out by a control device, as installed in the steam device. Advantageously, the steam device can be used in an energy-saving manner as a result of the method.

Von Vorteil ist auch ein Computer-Programmprodukt oder Computerprogramm mit Programmcode, der auf einem maschinenlesbaren Träger oder Speichermedium wie einem Halbleiterspeicher, einem Festplattenspeicher oder einem optischen Speicher gespeichert sein kann. Wird das Programmprodukt oder Programm auf einem Computer oder einer Steuervorrichtung ausgeführt, so kann das Programmprodukt oder Programm zur Durchführung, Umsetzung und/oder Ansteuerung der Schritte des Verfahrens nach einer der vorstehend beschriebenen Ausführungsformen verwendet werden.A computer program product or computer program with program code, which can be stored on a machine-readable carrier or storage medium such as a semiconductor memory, a hard disk memory or an optical memory, is also advantageous. If the program product or program is executed on a computer or a control device, then the program product or program can be used to carry out, implement and/or control the steps of the method according to one of the embodiments described above.

Figur 1 zeigt eine schematische Darstellung einer Bügeleinrichtung 100 gemäß einem Ausführungsbeispiel. Die Bügeleinrichtung 100 weist dabei eine Dampfvorrichtung 102, einen stationären Teil 104 und ein Handgerät 106 auf. Die Bügeleinrichtung 100 kann beispielsweise von einem Nutzer verwendet werden, um Textilien zu glätten, entsprechend zu bekannten Bügeleinrichtungen. Die Dampfvorrichtung 102 ist ausgebildet, um eine Dampffunktion der Bügeleinrichtung 100 zu ermöglichen. Die Dampfvorrichtung 102 weist dabei ein erstes Heizelement, eine Pumpe, ein zweites Heizelement und ein Abzweigelement auf, wie sie in einer der nachfolgenden Figuren näher beschrieben werden. Die Dampfvorrichtung 102 weist gemäß diesem Ausführungsbeispiel weiterhin eine auch als Steuerung bezeichnete Steuereinrichtung 103 auf, die ausgebildet ist, um um die Pumpe, das erste Heizelement, das zweite Heizelement und das Abzweigelement anzusteuern. figure 1 shows a schematic representation of an ironing device 100 according to an embodiment. The ironing device 100 has a steam device 102 , a stationary part 104 and a hand-held device 106 . The ironing device 100 can be used by a user, for example, to smooth textiles, corresponding to known ironing devices. The steam device 102 is designed to enable a steam function of the ironing device 100 . The steam device 102 has a first heating element, a pump, a second heating element and a branching element, as are described in more detail in one of the following figures. According to this exemplary embodiment, the steam device 102 also has a Control designated control device 103, which is designed to control the pump, the first heating element, the second heating element and the branching element.

Der stationäre Teil 104 umfasst gemäß diesem Ausführungsbeispiel ein Bügelbrett, das als Unterlage bei einem Bügelvorgang benutzbar ist. Das Handgerät 106 ist weiterhin als ein Bügeleisen realisiert, das beispielsweise über die zu glättenden Textilien führbar ist. Das Handgerät 106 weist dabei eine hier nicht dargestellte Mehrzahl von Austrittsöffnungen auf, die ausgebildet ist, um einen von dem ersten Heizelement erzeugten und/oder von dem zweiten Heizelement weiter erhitzten Dampf auszulassen. Optional weist das Handgerät 106 eine weitere Mehrzahl von Auftrittsöffnungen auf, die ausgebildet ist, um den von dem zweiten Heizelement weiter erhitzten Dampf auszulassen. Gemäß diesem Ausführungsbeispiel ist das erste Heizelement in dem stationären Teil 104 der Bügeleinrichtung 100 angeordnet und das zweite Heizelement sowie ein in einer der nachfolgenden Figuren beschriebenes Abzweigelement der Dampfvorrichtung 102 im Handgerät 106 angeordnet. Alternativ dazu sind das erste Heizelement, das zweite Heizelement und das Abzweigelement in dem stationären Teil 104 der Bügeleinrichtung 100 angeordnet oder anordenbar.According to this exemplary embodiment, the stationary part 104 comprises an ironing board which can be used as a base during an ironing process. The hand-held device 106 is also implemented as an iron, which can be guided, for example, over the textiles to be smoothed. The hand-held device 106 has a plurality of outlet openings, not shown here, which are designed to let out steam generated by the first heating element and/or further heated by the second heating element. Optionally, the hand-held device 106 has a further plurality of discharge openings configured to release the vapor further heated by the second heating element. According to this exemplary embodiment, the first heating element is arranged in the stationary part 104 of the ironing device 100 and the second heating element and a branching element, described in one of the following figures, of the steam device 102 are arranged in the hand-held device 106 . Alternatively, the first heating element, the second heating element and the branching element are arranged or can be arranged in the stationary part 104 of the ironing device 100 .

In anderen Worten ausgedrückt wird die auch als Dampferzeuger bezeichnenbare Dampfvorrichtung 102 mit einer Zusatzheizung, die hier als zweites Heizelement bezeichnet ist, und einer so genannten ECO-Funktion für eine Bügeleinrichtung 100 vorgestellt, die auch als Bügelsystem bezeichnet wird. Der stationäre Teil 104 umfasst gemäß diesem Ausführungsbeispiel eine Bügelfläche 108 und ein Gestell 110. Durch den hier vorgestellten Ansatz wird eine sehr schnelle Betriebsbereitschaft gewährleistet, wie es beispielsweise bei Systemen ohne Energiespeicher üblich ist, im betriebsbereiten Zustand wird jedoch aktiv auf eine vorliegende Belastungssituation reagiert. Dazu werden beispielsweise Niedriglastphasen genutzt, um einen Speicher zu laden, aus dem in Höchstlastphasen, die auch als Boostsituation oder Dampfboost bezeichnet wird, Energie entnommen wird. Durch aktives Abschalten des ansonsten autonom im Hintergrund arbeitenden Systems durch den Benutzer wird gemäß diesem Ausführungsbeispiel zudem ein Energiesparmodus, die auch als ECO Funktion bezeichnet wird, bereitgestellt.In other words, the steam device 102, which can also be referred to as a steam generator, is presented with an additional heater, which is referred to here as a second heating element, and a so-called ECO function for an ironing device 100, which is also referred to as an ironing system. According to this exemplary embodiment, the stationary part 104 comprises an ironing surface 108 and a frame 110. The approach presented here ensures very rapid operational readiness, as is usual, for example, in systems without an energy storage device, but in the operational state there is an active response to a given load situation. For this purpose, for example, low-load phases are used to charge a storage device, from which energy is taken in peak-load phases, which is also referred to as a boost situation or steam boost. According to this exemplary embodiment, an energy-saving mode, which is also referred to as an ECO function, is also provided by the user actively switching off the system that is otherwise working autonomously in the background.

Figur 2 zeigt eine schematische Darstellung einer Dampfvorrichtung 102 gemäß einem Ausführungsbeispiel. Die hier dargestellte Dampfvorrichtung 102 kann der in Figur 1 beschriebenen Dampfvorrichtung 102 entsprechen oder ähneln und kann dem entsprechend in oder an einer ein Handgerät 106 umfassenden Bügeleinrichtung angeordnet sein. Die Dampfvorrichtung 102 weist dabei die Pumpe 200, das erste Heizelement 202, das Abzweigelement 204 sowie das zweite Heizelement 206 auf. Die Pumpe 200 ist ausgebildet, um eine Flüssigkeit, wie beispielsweise Wasser, von einem Vorratsbehälter 208 zu dem ersten Heizelement 202 zu pumpen. Das erste Heizelement 202 ist ausgebildet, um die Flüssigkeit zumindest teilweise zu verdampfen und als Dampf bereitzustellen. Bei einer ersten Fördermenge der Pumpe 200 ist das erste Heizelement 202 ausgebildet, um die Flüssigkeit vollständig zu verdampfen. Bei einer gegenüber der ersten Fördermenge erhöhten zweiten Fördermenge der Pumpe 200 ist das erste Heizelement 202 aufgrund seiner Heizleistung ausgebildet, um die dem zweiten Heizelement 202 zugeführte Flüssigkeit nur teilweise zu verdampfen. Das Abzweigelement 204 weist eine einem Normalbetriebszustand der Bügeleinrichtung zugeordnete Normalstellung und eine einem Boostzustand der Bügeleinrichtung zugeordnete Booststellung auf und ist ausgebildet, um den Dampf in der Normalstellung an das Handgerät 106 bereitzustellen und in der Booststellung zu dem zweiten Heizelement 206 zu leiten. Das zweite Heizelement 206 ist ausgebildet, um den von dem ersten Heizelement 202 bereitgestellten Dampf weiter zu erhitzen und als weiter erhitzten Dampf an das Handgerät 106 bereitzustellen. figure 2 10 shows a schematic representation of a steam device 102 according to an exemplary embodiment. The steam device 102 shown here can be the one shown in figure 1 correspond to or are similar to the steam device 102 described and can accordingly be arranged in or on an ironing device comprising a hand-held device 106 . The steam device 102 has the pump 200 , the first heating element 202 , the branching element 204 and the second heating element 206 . The pump 200 is designed to a liquid, such as water, from a reservoir 208 to the to pump the first heating element 202 . The first heating element 202 is designed to at least partially vaporize the liquid and make it available as a vapor. At a first flow rate of the pump 200, the first heating element 202 is designed to completely vaporize the liquid. When the second delivery rate of the pump 200 is increased compared to the first delivery rate, the first heating element 202 is designed because of its heat output to only partially evaporate the liquid supplied to the second heating element 202 . The branching element 204 has a normal position associated with a normal operating state of the ironing device and a boost position associated with a boosted state of the ironing device and is designed to provide the steam to the hand-held device 106 in the normal position and to direct the steam to the second heating element 206 in the boosted position. The second heating element 206 is designed to further heat the steam provided by the first heating element 202 and to provide it to the hand-held device 106 as further heated steam.

Gemäß diesem Ausführungsbeispiel sind das erste Heizelement 202 und das zweite Heizelement 206 als Thermoblock ausgeformt, die Wärmeenergie speichern und bei Bedarf zur Dampferzeugung nutzen können. Gemäß diesem Ausführungsbeispiel weist die Dampfvorrichtung 102, wie auch in Figur 1 schon beschrieben, die Steuereinrichtung 103 auf, die ausgebildet ist, um die Pumpe 200, das erste Heizelement 202, das zweite Heizelement 206 und das Abzweigelement 204 anzusteuern. Die Steuereinrichtung 103 ist dabei ausgebildet, um während des Normalbetriebszustands eine erste Fördermenge der Pumpe 200 und während des Boostzustands eine zweite Fördermenge der Pumpe 200 einzustellen. Dabei ist die zweite Fördermenge gemäß diesem Ausführungsbeispiel größer als die erste Fördermenge. Gemäß diesem Ausführungsbeispiel ist die Steuereinrichtung 103 ferner ausgebildet, um das zweite Heizelement 206 zu beheizen, wenn das erste Heizelement 202 eine Solltemperatur aufweist. Das bedeutet, dass die Steuereinrichtung 103 das erste Heizelement 202 gegenüber dem zweiten Heizelement 206 priorisiert. Weiterhin optional ist die Steuereinrichtung 103 ausgebildet, um ein Anzeigesignal 210 zum Anzeigen einer Boostbereitschaft der Bügeleinrichtung bereitzustellen, wenn das zweite Heizelement 206 eine weitere Solltemperatur aufweist. Dazu kann eine geeignete Anzeigeeinrichtung eingesetzt werden. Beispielsweise wird die Boostbereitschaft mittels einer LED für einen Nutzer sichtbar angezeigt. Gemäß diesem Ausführungsbeispiel ist die Steuereinrichtung 103 weiterhin ausgebildet, um das Abzweigelement 204 ansprechend auf eine Boostanforderung, wie beispielsweise ansprechend auf ein Boostsignal 212 bei einer Betätigung einer Taste, in die Booststellung zu überführen. Die Taste ist beispielsweise an dem Handgerät 106 oder alternativ an dem stationören Teil angeordnet. Alternativ zu einer Taste kann auch eine andere geeignete Eingabeeinrichtung verwendet werden. Weiterhin optional ist die Steuereinrichtung 103 ausgebildet, um das Abzweigelement 204 in die Normalstellung zu überführen, wenn das zweite Heizelement 206 eine Mindesttemperatur unterschreitet. Das bedeutet zusammengefasst, dass die Steuereinrichtung 103 ausgebildet ist, um den Normalbetrieb zu priorisieren. Der Boostbetrieb kann dagegen temporär von dem Nutzer angefordert werden.According to this exemplary embodiment, the first heating element 202 and the second heating element 206 are formed as a thermal block that can store heat energy and use it to generate steam if required. According to this exemplary embodiment, the steam device 102, as also in figure 1 already described, the control device 103, which is designed to control the pump 200, the first heating element 202, the second heating element 206 and the branch element 204. The control device 103 is designed to set a first delivery rate of the pump 200 during the normal operating state and a second delivery rate of the pump 200 during the boost state. The second flow rate according to this embodiment is greater than the first flow rate. According to this exemplary embodiment, the control device 103 is also designed to heat the second heating element 206 when the first heating element 202 has a setpoint temperature. This means that the control device 103 prioritizes the first heating element 202 over the second heating element 206 . Also optionally, the control device 103 is designed to provide a display signal 210 for displaying a boost readiness of the ironing device when the second heating element 206 has a further setpoint temperature. A suitable display device can be used for this purpose. For example, the readiness for boosting is displayed visibly for a user by means of an LED. According to this exemplary embodiment, the control device 103 is also designed to convert the branching element 204 into the boost position in response to a boost request, such as in response to a boost signal 212 when a button is actuated. The button is arranged, for example, on the handset 106 or alternatively on the stationary part. As an alternative to a button, another suitable input device can also be used. Also optionally, the control device 103 is designed to convert the branching element 204 into the normal position when the second heating element 206 falls below a minimum temperature. The means in summary that the control device 103 is designed to prioritize normal operation. The boost mode, on the other hand, can be requested temporarily by the user.

In anderen Worten wird gemäß diesem Ausführungsbeispiel zur Dampferzeugung das erste Heizelement 202, das auch als erster Thermoblock T1 bezeichnet wird, eingesetzt, um durch eine geringe aufzuheizende Masse eine schnelle Dampfbereitschaft zu gewährleisten. Das erste Heizelement 202 wird durch die Pumpe 200 mit der Flüssigkeit versorgt, die aus dem Vorratsbehälter 208 angesaugt wird. Das erste Heizelement 202 wird für den Normalbetrieb genutzt und ist von seiner Leistung derart ausgelegt, dass es eine komplette zur Verfügung stehende elektrische Energie abzüglich der Energie für das Handgerät 106, die für die Steuereinrichtung 103 und eventuell für die vorhandene Zusatzaggregate, wie beispielsweise einen Lüfter oder eine Bügeltischheizung, benötigte Energie, ausnutzt. Die Förderleistung der Pumpe 200 ist dabei darauf abgestimmt, dass im Normalbetriebszustand nicht mehr Flüssigkeit gefördert wird, als sicher durch das erste Heizelement 202 verdampft werden kann. Dadurch wird beispielsweise verhindert, dass es zum Tropfen oder Spucken aus dem Handgerät 106 kommt.In other words, according to this exemplary embodiment, the first heating element 202, which is also referred to as the first thermal block T1, is used to generate steam in order to ensure rapid steam readiness due to a small mass to be heated. The first heating element 202 is supplied by the pump 200 with the liquid which is drawn in from the reservoir 208 . The first heating element 202 is used for normal operation and is designed in terms of its output in such a way that all the available electrical energy is available minus the energy for the hand-held device 106, for the control device 103 and any additional units that are present, such as a fan or an ironing board heater, uses the energy required. The pumping capacity of the pump 200 is adjusted so that in the normal operating state no more liquid is pumped than can safely be vaporized by the first heating element 202 . This prevents, for example, dripping or spitting from the handset 106 .

In einem Pfad 213 von dem ersten Heizelement 202 zum Dampfauslass, das bedeutet zu der Mehrzahl von Auslassöffnungen, ist das Abzweigelement 204 zwischengeschaltet, das den Pfad 213 in einen ersten Dampfpfad 214 und einen zweiten Dampfpfad 216 teilt. Der erste Dampfpfad 214 führt vom Abzweigelement 204 direkt zu dem Handgerät 106 und ist im Normalbetrieb der alleinig freigegebene Pfad. Der zweite Dampfpfad 216 führt dagegen zunächst zu dem zweiten Heizelement 206, das als Energiespeicher für die Boostfunktion nutzbar ist. Durch die zuvor beschriebene Leistungsauslegung kann das zweite Heizelement 206 erst dann mit Energie versorgt werden, wenn das erste Heizelement 202 vollständig aufgeheizt ist und keine weitere Energie mehr benötigt. Die Leistung des zweiten Heizelements 206 kann entsprechend ebenso groß wie die des ersten Heizelements 202 sein, da das erste Heizelement 202 und das zweite Heizelement 206 nicht zeitgleich betrieben werden. Wird während der Aufheizphase des zweiten Heizelements 206 eine Dampftaste betätigt, wird die Energieversorgung unmittelbar wieder an das erste Heizelement 202 zurückgegeben, sodass dieses priorisiert wird und den Normalbetrieb sicherstellt.In a path 213 from the first heating element 202 to the steam outlet, ie to the plurality of outlet openings, the branching element 204 is interposed, which divides the path 213 into a first steam path 214 and a second steam path 216 . The first vapor path 214 leads from the branching element 204 directly to the hand-held device 106 and is the only path that is released during normal operation. The second vapor path 216, on the other hand, first leads to the second heating element 206, which can be used as an energy store for the boost function. As a result of the power configuration described above, the second heating element 206 can only be supplied with energy when the first heating element 202 has been completely heated up and no longer requires any further energy. Accordingly, the output of the second heating element 206 can be just as great as that of the first heating element 202, since the first heating element 202 and the second heating element 206 are not operated at the same time. If a steam button is pressed during the heating-up phase of the second heating element 206, the energy supply is immediately returned to the first heating element 202, so that this is prioritized and normal operation is ensured.

Im weiteren Verlauf führt auch der zweite Dampfpfad 216 zum Handgerät 106. Der zweite Dampfpfad 216 kann dabei beispielsweise wieder mit dem ersten Dampfpfad 214 zusammengeführt werden und die gleichen Austrittsöffnungen nutzen. Alternativ bleiben beide Dampfpfade 214, 216 separiert und es werden separate Austrittsöffnungen genutzt.In the further course, the second steam path 216 also leads to the hand-held device 106. The second steam path 216 can, for example, be combined again with the first steam path 214 and use the same outlet openings. Alternatively, both vapor paths 214, 216 remain separate and separate exit openings are used.

Sobald das zweite Heizelement 206 seine festgelegte Solltemperatur erreicht, wird dem Nutzer dies signalisiert, indem lediglich optional beispielsweise eine "Boost-LED" oder eine vergleichbare Anzeige aktiviert wird. Ab diesem Zeitpunkt ist gemäß diesem Ausführungsbeispiel die Funktion einer Boost-Taste freigegeben, durch die ein Dampfboost auslösbar ist. Sobald ein Dampfboost ausgelöst wird, wird gemäß diesem Ausführungsbeispiel das Abzweigelement 204 derart verstellt, dass der erste Dampfpfad 214 verschlossen und der zweite Dampfpfad 216 freigegeben ist. Andererseits wird die Pumpe 200 in Betrieb genommen und auf die zweite Fördermenge eingestellt, die größer ist als die erste Fördermenge im Normalbetriebszustand. Durch die Auslegung des ersten Heizelements 202 auf die erste Fördermenge führt die zweite Fördermenge dazu, dass die geförderte Flüssigkeit nicht mehr vollständig im ersten Heizelement 202 verdampft. Dadurch wird ein Gemisch aus flüssiger und verdampfter Flüssigkeit von dem ersten Heizelement 202 über das Abzweigelement 204 bis in das zweite Heizelement 206 gefördert. Da das zweite Heizelement 206 zuvor auf eine geeignete Temperatur aufgeheizt wurde, steht dort ausreichend Energie zur Verfügung, um die mitgeführte Flüssigkeit vollständig zu verdampfen. Das bedeutet, dass die reale Verdampfungsleistung in einer Boostphase deutlich über einer Dauerdampfleistung im Normalbetriebszustand liegt. Während das zweite Heizelement 206 die zuvor gespeicherte Energie an das Flüssigkeit-Dampf-Gemisch abgibt, kühlt es sich schnell ab. Daher ist es sinnvoll, die Dampfvorrichtung 102 rechtzeitig wieder in den Normalbetriebszustand zurückzukehren zu lassen. Hierzu wird die Förderleistung der Pumpe 200 wieder reduziert und anschließend das Abzweigelement 204 wieder in seinen Ursprungszustand gebracht. Über Temperatur, Werkstoff und Masse des zweiten Heizelements 206 kann die gespeicherte Energie bestimmt werden. Weiterhin kann durch entsprechende Wahl und Auslegung dieser Parameter eine gewünschte Speicherkapazität erreicht werden. In Kombination mit entsprechenden Daten des ersten Heizelements 202 sowie der Verdampfungsenthalpie der Flüssigkeit und der gewünschten Dampftemperatur kann genau spezifiziert werden, wie viel Flüssigkeit während eines Boosts umgesetzt werden darf, ohne das System zu überfordern und damit zu unterkühlen. Die Einhaltung dieser Grenze stellt eine Tropffreiheit des Systems im Anschluss an einen Boost sicher.As soon as the second heating element 206 reaches its set target temperature, this is signaled to the user by only optionally, for example, a “boost LED” or a comparable display is activated. From this point in time, according to this exemplary embodiment, the function of a boost button is released, which can be used to trigger a steam boost. As soon as a steam boost is triggered, according to this exemplary embodiment, the branching element 204 is adjusted in such a way that the first steam path 214 is closed and the second steam path 216 is opened. On the other hand, the pump 200 is operated and set to the second delivery rate, which is larger than the first delivery rate in the normal operating state. Due to the design of the first heating element 202 for the first delivery rate, the second delivery rate means that the liquid delivered no longer evaporates completely in the first heating element 202 . As a result, a mixture of liquid and vaporized liquid is conveyed from the first heating element 202 via the branch element 204 to the second heating element 206 . Since the second heating element 206 has previously been heated to a suitable temperature, sufficient energy is available there to completely vaporize the entrained liquid. This means that the real evaporation capacity in a boost phase is significantly higher than a continuous evaporation capacity in normal operating conditions. As the second heating element 206 releases the previously stored energy to the liquid-vapor mixture, it cools rapidly. Therefore, it makes sense to allow the vapor device 102 to return to the normal operating state in good time. For this purpose, the delivery rate of the pump 200 is reduced again and then the branching element 204 is returned to its original state. The stored energy can be determined via the temperature, material and mass of the second heating element 206 . Furthermore, a desired storage capacity can be achieved by appropriate selection and design of these parameters. In combination with corresponding data from the first heating element 202 as well as the vaporization enthalpy of the liquid and the desired vapor temperature, it is possible to specify exactly how much liquid can be converted during a boost without overtaxing the system and thus undercooling. Compliance with this limit ensures that the system is drip-free after a boost.

Nach einem Boost benötigt die Dampfvorrichtung 102 zunächst wieder eine Phase mit geringerer Auslastung, um das zweite Heizelement 206 wieder auf seine Solltemperatur zu erhitzen. Wenn der Nutzer die Dampfvorrichtung 102 in den ECO-Modus versetzt, wird das zweite Heizelement 206 zu keinem Zeitpunkt und in keiner Lastsituation aufgeheizt, wodurch gegenüber dem Normalbetriebszustand Energie gespart wird. Wenn der Nutzer die Boostfunktion nicht nutzt, den ECO-Modus aber auch nicht aktiviert hat, wird einmalig eine größere Energiemenge benötigt, um das zweite Heizelement 206 auf seine Betriebstemperatur zu bringen. Im Anschluss daran wird aber nur eine geringe Energiemenge benötigt, um die unvermeidbaren Wärmeverluste zu kompensieren.After a boost, the steam device 102 first needs a phase with a lower load in order to heat the second heating element 206 back to its setpoint temperature. When the user puts the vaping device 102 in ECO mode, the second heating element 206 is not heated at any time and in any load situation, thereby saving energy compared to the normal operating state. If the user does not use the boost function but has not activated the ECO mode either, a larger amount of energy is required once to bring the second heating element 206 to its operating temperature. After that, however, only a small amount of energy is required to compensate for the unavoidable heat losses.

Gemäß diesem Ausführungsbeispiel ist das erste Heizelement 202 im stationären Teil der Bügeleinrichtung platziert. Das Abzweigelement 204 und das zweite Heizelement 206 sind direkt am Handgerät 106 angeordnet. Diese Variante zeichnet sich durch eine sehr kurze Strecke zwischen dem zweiten Heizelement 206 und der Mehrzahl von Austrittsöffnungen aus. Dadurch sind Druckverluste während eines Boosts weitestgehend ausgeschlossen. Zudem kann auf sehr einfache Weise ein separater Dampfaustritt mittels einer weiteren Mehrzahl von Austrittsöffnungen für den Dampfboost realisiert werden, um eine subjektive Wirkung für den Nutzer noch zu verstärken. Aus Ergonomieaspekten ist die thermische Speichermasse bei dem hier beschriebenen Ansatz nicht beliebig hoch wählbar, um eine Bedienbarkeit durch zu hohes Gewicht für den Nutzer nicht unnötig zu erschweren.According to this embodiment, the first heating element 202 is placed in the stationary part of the ironing device. The branching element 204 and the second heating element 206 are arranged directly on the hand-held device 106 . This variant is characterized by a very short distance between the second heating element 206 and the plurality of outlet openings. As a result, pressure losses during a boost are largely excluded. In addition, a separate steam outlet can be realized in a very simple manner by means of a further plurality of outlet openings for the steam boost, in order to further increase the subjective effect for the user. For ergonomic reasons, the thermal storage mass in the approach described here cannot be chosen to be as high as desired, in order not to unnecessarily complicate operation for the user due to excessive weight.

Alternativ sind beide Heizelemente 202, 206 und dementsprechend auch das Abzweigelement 204 im stationären Teil der Bügeleinrichtung angeordnet. Bei dieser Ausführungsform ist besonders vorteilhaft, dass durch einen geringen Abstand zwischen dem ersten Heizelement 202 und dem zweiten Heizelement 206 eine besonders kurze Reaktionszeit erreicht wird. Verschleppte Flüssigkeit aus dem ersten Heizelement 202 erreicht mit minimalem Zeitversatz das zweite Heizelement 206, wo es verdampft wird. Durch eine damit einhergehende Volumenzunahme erhöht sich eine Strömungsgeschwindigkeit in einem Verbindungsschlauch zum Handgerät 106 deutlich, wodurch der Dampf besonders schnell die Austrittsöffnungen erreicht. Zudem werden Kondensationseffekte oder verschleppte Flüssigkeit zwischen den beiden Heizelementen 202, 206 weitestgehend ausgeschlossen und sind daher gut beherrschbar.Alternatively, both heating elements 202, 206 and accordingly also the branching element 204 are arranged in the stationary part of the ironing device. In this embodiment, it is particularly advantageous that a particularly short reaction time is achieved due to a small distance between the first heating element 202 and the second heating element 206 . Liquid carried over from the first heating element 202 reaches the second heating element 206 with a minimal time lag, where it is vaporized. A flow rate in a connecting hose to the hand-held device 106 increases significantly as a result of an associated increase in volume, as a result of which the steam reaches the outlet openings particularly quickly. In addition, condensation effects or entrained liquid between the two heating elements 202, 206 are largely ruled out and are therefore easy to control.

Zusammengefasst wird durch den beschriebenen Ansatz kurzzeitig eine messbar höhere Dampfmenge ermöglicht als es allein durch die konstant zur Verfügung stehende elektrische Leistung möglich wäre. Dennoch wird eine Bereitschaftszeit nach Einschalten des Gerätes nicht verlängert, wie es durch große Speichermassen am ersten Heizelement 202 die Folge wäre. Eine ECO-Funktion ist zudem leicht realisierbar. Alle Komponenten sind dabei additiv zu einer regulären Dampferzeugung realisiert oder realisierbar.In summary, the described approach enables a measurably higher amount of steam for a short time than would be possible with the constantly available electrical power alone. Nevertheless, a standby time after the device is switched on is not extended, as would be the result of large storage masses on the first heating element 202 . An ECO function is also easy to implement. All components are realized or can be realized in addition to regular steam generation.
