(Wasser-)Dampf für den Wellness- und therapeutischen Bereich soll oftmals aromatisiert sein, um die Wirkung des Dampfes zu erhöhen und/oder um ein Dampfbad oder eine Dampfdusche für den Anwender angenehmer zu machen. Dazu sind am Dampfgenerator Vorrichtungen angeordnet, in denen Aromen eingefüllt werden können, die bei Vorbeistreichen des Dampfes Aroma an den Dampf abgeben. Aus der
Es ist daher eine Aufgabe der gegenständlichen Erfindung, einen Dampferzeuger mit der Möglichkeit der Aromatisierung des Dampfes anzugeben, der ein Nachfüllen von Aromastoffen ermöglicht, ohne das die Gefahr des Verbrühens für einen Anwender besteht.It is therefore an object of the subject invention to provide a steam generator with the possibility of aromatization of the steam, which allows refilling of flavors without the risk of scalding for a user.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in der Aromaaufnahme ein Aromabehälter zur Aufnahme von Aroma angeordnet wird, wobei die Aromaeinheit ein Aromaeinheitgehäuse aufweist, in dem eine Aromaaufnahme angeordnet ist und die Aromaaufnahme relativ zum Aromaeinheitgehäuse bewegbar angeordnet ist, in der Aromaaufnahme ein erster Strömungsbereich vorgesehen ist, der durch zwei Dichtelement gegenüber dem Aromaeinheitgehäuse begrenzt ist und im ersten Strömungskanal der Aromabehälter angeordnet ist, wobei der erste Strömungsbereich in einer ersten Position den Dampferzeuger mit dem Dampfanschluss verbindet und in der Aromaaufnahme ein zweiter Strömungsbereich vorgesehen ist, der durch zwei Dichtelemente gegenüber dem Aromaeinheitgehäuse begrenzt ist, wobei der zweite Strömungsbereich in einer zweiten Position den Dampferzeuger mit dem Dampfanschluss verbindet. Die Aromaaufnahme funktioniert dabei wie ein Schieberventil, was es ermöglicht, Aroma ohne Gefahr für die bedienende Person bei vollem Betrieb des Dampferzeugers in die Aromauafnahme nachzufüllen. Die vorgesehenen Dichtelemente stellen dabei sicher, dass beim Nachfüllen kein heißer Dampf austreten kann.This object is achieved in that in the aroma receptacle, an aroma container for receiving aroma is arranged, wherein the aroma unit has a Aromaeinheitgehäuse in which an aroma receptacle is arranged and the aroma receptacle is arranged movable relative to Aromaeinheitgehäuse movable, provided in the aroma receptacle, a first flow area which is delimited by two sealing element with respect to the aroma unit housing and is arranged in the first flow channel of the aroma container, wherein the first flow region in a first position connects the steam generator to the steam connection and in the aroma receptacle a second flow region is provided which is separated by two sealing elements Aroma unit housing is limited, wherein the second flow region in a second position connects the steam generator with the steam connection. The aroma recording works like a slide valve, which makes it possible to refill aroma without danger to the operator with full operation of the steam generator in the aroma intake. The provided sealing elements ensure that no hot steam can escape during refilling.
Der Dampferzeuger kann sehr einfach von außen zugänglich gemacht werden, z.B. zum Einfüllen eines Entkalkungsmittels, wenn in der Aromaaufnahme ein dritter Strömungsbereich und ein Verschlussmittel zum Verschließen des dritten Strömungsbereiches vorgesehen wird, wobei der dritte Strömungsbereich mit der Verbindungsleitung verbunden ist. Damit kann die Bedienung und die Wartung des Dampfgenerators sehr vereinfacht werden. Ganz besonders vorteilhaft ist es dabei, als Verschlussmittel den in einer Aromabehälteraufnahme angeordneten Aromabehälter selbst vorzusehen.The steam generator can be made very easily accessible from the outside, eg for filling a descaling agent, if in the aroma receptacle, a third flow area and a closure means for closing the third flow area is provided, wherein the third flow area is connected to the connecting line. In order to The operation and maintenance of the steam generator can be greatly simplified. It is particularly advantageous in this case to provide as closure means the aroma container arranged in a flavor container receptacle itself.
Besonders vorteilhaft wird das Gehäuse des Dampfgenerators durch eine darin angeordnete Trennwand zweigeteilt, wobei in einem ersten Gehäuseteil eine Elektrikeinheit angeordnet ist und in einem zweiten Gehäuseteil ein Dampferzeuger angeordnet ist und an der Trennwand eine Kühleinheit angeordnet ist, in der eine Ausnehmung vorgesehen ist, durch die Kühlmedium fließt. Hierbei wird der Dampfgenerator durch eine Trennwand in zwei Bereiche getrennt wobei die Trennwand gekühlt wird. Damit wird ermöglicht, die Komponenten des Dampfgenerators, die von Ihrer Funktion her eine hohe Arbeitstemperatur haben (wie z.B. der Dampferzeuger) und die Komponenten, die nur bis zu einer vorgegebenen Temperatur betrieben werden dürfen (wie z.B. die Elektronik) in unterschiedlichen Bereichen im Dampfgenerator anzuordnen, wobei die Bereiche durch eine gekühlte Trennwand getrennt sind. So kann sichergestellt werden, dass die Temperatur in bestimmten Bereichen des Dampfgenerators nicht zu hoch wird. Gleichzeitig wird dadurch aber auch das Gehäuse selbst gekühlt. Dadurch wird es möglich alle benötigten Komponenten trotzdem in einem kompakten Gehäuse unterzubringen und damit einen kompakten Dampfgenerator zu realisieren.Particularly advantageously, the housing of the steam generator is divided into two by a partition wall arranged therein, wherein in a first housing part, an electric unit is arranged and in a second housing part, a steam generator is arranged and on the partition wall, a cooling unit is arranged, in which a recess is provided through the Coolant flows. In this case, the steam generator is separated by a partition wall into two areas wherein the partition wall is cooled. This makes it possible to arrange the components of the steam generator, which have a high working temperature due to their function (such as the steam generator) and the components that can only be operated up to a predetermined temperature (such as the electronics) in different areas in the steam generator wherein the areas are separated by a cooled partition. This ensures that the temperature in certain areas of the steam generator is not too high. At the same time, however, this also cools the housing itself. This makes it possible to accommodate all the components needed in a compact housing and thus to realize a compact steam generator.
Ganz besonders vorteilhaft mündet in die Ausnehmung der Kühleinheit eine Anschlussleitung für Wasser für den Dampfgenerator. Damit kann der Dampfgenerator an den Hauswasseranschluss angeschlossen werden und das kalte Wasser für den Betrieb des Dampfgenerators kann gleichzeitig auch zur Kühlung herangezogen werden. Dazu ist vorzugsweise auch vorgesehen, dass in der Ausnehmung eine Zuführleitung für Wasser für den Dampferzeuger mündet. Dass kalte Wasser fließt damit vom Hauswasseranschluss in die Kühleinheit, kühlt dort die Trennwand(und andere Teile bzw. Bereiche des Dampfgenerators) und fließt dann weiter in den Dampferzeuger. Damit lässt sich ein besonders einfach aufgebauter und kompakter Dampfgenerator realisieren.Very particularly advantageous opens into the recess of the cooling unit, a connecting line for water for the steam generator. Thus, the steam generator can be connected to the domestic water connection and the cold water for the operation of the steam generator can also be used for cooling. For this purpose, it is preferably also provided that a feed line for water for the steam generator opens in the recess. That cold water flows from the domestic water connection into the cooling unit, where it cools the partition (and other parts or areas of the steam generator) and then flows on into the steam generator. This makes it possible to realize a particularly simple and compact steam generator.
Um eine möglichst gute Kühlwirkung zu erzielen, wird das Kühlmedium in der Kühleinheit geführt, indem in der Ausnehmung eine Abtrennung vorgesehen ist, wobei die ersten Leitung im Bereich der Abtrennung mündet und die zweite Leitung im Bereich der anderen Seite der Abtrennung mündet. Damit fließt das Kühlmedium erzwungenermaßen durch die ganze Kühleinheit, was einen größtmöglichen Kontakt von Kühlmedium mit dem zu kühlenden Bauteil sicherstellt.In order to achieve the best possible cooling effect, the cooling medium is guided in the cooling unit by a separation is provided in the recess, wherein the first line opens in the region of the separation and the second line opens in the region of the other side of the separation. Thus, the cooling medium forcibly flows through the entire cooling unit, which ensures the greatest possible contact of the cooling medium with the component to be cooled.
Um eine einfache Nachfüllung von Wasser in den Dampferzeuger ohne Unterbrechung des Dampfens und eine sichere Entleerung ohne der Gefahr der Verbrühung vor Personen zu ermöglichen, wird der Dampferzeuger mit einer Zuführleitung zur Zufuhr von kaltem Wasser und einer Entleerleitung zur Entleerung des Dampferzeugers verbunden, wobei in der Zuführleitung ein Füllventil und in der Entleerleitung ein Entleerventil angeordnet ist, die von einer Steuereinheit impulsförmig ansteuerbar sind, wobei die Steuereinheit die Öffnen- und Schließzeiten des Füllventils und/oder des Entleerventils in Abhängigkeit vom Druck des zugeführten kalten Wassers ermittelt. Der Wasserdruck muss dabei nur einmal bestimmt werden und die benötigten Öffnen- und Schließzeiten der Ventile können in Abhängigkeit davon festgelegt werden. Zusätzlich können noch die Anzahl der Füllimpulse und/oder die Entleerdauer in Abhängigkeit vom Druck des zugeführten kalten Wassers ermittelt werden. Die Steuerung der Nachfüllung von Wasser und der Entleerung des Dampferzeugers kann so sehr vereinfacht werden.In order to allow a simple refilling of water into the steam generator without interrupting the steam and a safe emptying without the risk of scalding people, the steam generator with a supply line for the supply of cold water and an emptying line for emptying the steam generator, wherein in the feed line a filling valve and in the emptying line an emptying valve is arranged, which are pulse-controlled by a control unit, wherein the control unit, the opening and closing times of the filling valve and / or the emptying valve in dependence Pressure of the supplied cold water determined. The water pressure must be determined only once and the required opening and closing times of the valves can be set depending on it. In addition, the number of filling pulses and / or the emptying duration can be determined as a function of the pressure of the supplied cold water. The control of the replenishment of water and the emptying of the steam generator can be so much simplified.
Noch weitere wird die Steuerung vereinfacht, wenn im Dampfgenerator eine Speichereinheit vorgesehen ist, in der die Öffnen- und Schließzeiten des Füllventils und/oder des Entleerventils und/oder die Anzahl der Füllimpulse und/oder die Entleerdauer in Abhängigkeit vom Wasserdruck hinterlegt sind. Die benötigten Einstellungen müssen dann nur mehr zum herrschenden Wasserdruck korrespondierend aus der Speichereinheit entnommen werden.Still further, the control is simplified when a memory unit is provided in the steam generator, in which the opening and closing times of the filling valve and / or the emptying valve and / or the number of filling pulses and / or the emptying time depending on the water pressure are stored. The required settings must then be removed from the storage unit corresponding only to the prevailing water pressure.
Der Wasserdruck kann sehr einfach ermittelt werden, indem mit Hilfe eines Niveausensors die Füllzeit bis zum Erreichen eines festgelegten Wasserstandes im Dampferzeuger gemessen wird. Aus der gemessenen Füllzeit kann dann direkt auf den herrschenden Wasserdruck rückgeschlossen werden.The water pressure can be determined very easily by measuring the filling time until a defined water level in the steam generator is reached with the aid of a level sensor. From the measured filling time can then be deduced directly on the prevailing water pressure.

Der erfindungsgemäße Dampfgenerator 1, z.B. für eine Dampfdusche, umfasst ein Gehäuse 2, in dem alle Komponenten des Dampfgenerators 1 angeordnet sind, und einen Deckel 3, wie in
Im Dampfgenerator 1 ist, wie in
Das Gehäuse 2 des Dampfgenerators 1 ist durch eine Trennwand 17 zweigeteilt. In einem ersten Gehäuseteil des Dampfgenerators 1, hier im oberen Bereich des Gehäuses 2, ist hier in einer Elektrikeinheit 16 die notwendige Elektronik und Elektrik, z.B. für den Stromanschluss und die Steuerung des Dampfgenerators, angeordnet. Die Elektrikeinheit 16 ist elektrisch mit der Bedieneinheit 4 verbunden. Da die Elektrikeinheit 16, und vor allem die darin befindliche Elektronik, nur bis zu bestimmten vorgegebenen und spezifizierten Temperaturen funktionsfähig ist, ist im Gehäuse 2 eine Trennwand 17 vorgesehen, die einen heißen Gehäuseteil, hier ein unterer Bereich des Gehäuses 2, in dem der Dampferzeuger 10 zur Dampferzeugung angeordnet ist, vom oberen Gehäuseteil, in dem die Elektrikeinheit 16 angeordnet ist, trennt. Die Trennwand 17 kann dazu durch das zugeführte kalte Wasser gekühlt werden, wie weiter unten unter Bezugnahme auf die
In der Elektrikeinheit 16 kann auch eine Steuereinheit 29 vorgesehen sein, die die Funktionen des Dampfgenerators 1 regelt. Die Steuereinheit 29 kann mit der Bedieneinheit 4 verbunden sein. Z.B. kann die Dampferzeugung in Abhängigkeit von einer gewünschten Kabinentemperatur einer Dampfdusche geregelt werden.In the
Über eine Anschlussleitung 21 mit einem Anschluss 23, die über eine Armatur am Hauswasseranschluss angeschlossen wird, wird kaltes Wasser einer Kühleinheit 20 zugeführt. Von der Kühleinheit 20 wird das kalte Wasser über eine Zuführleitung 22 dem Dampferzeuger 10 zugeführt. Die Steuerung der Wasserzufuhr erfolgt über ein Füllventil 25, das durch die Elektrikeinheit 16 angesteuert wird, wie weiter unten im Detail beschrieben. Die Anschlussleitung 21 (die in diesem Fall auch gleichzeitig die Zuführleitung 22 wäre) könnte aber auch direkt mit dem Dampferzeuger 10 verbunden sein. Für die Kühleinheit 20 könnte dann eine eigene Leitung 58 vorgesehen sein, über die ein Kühlmedium, vorzugsweise kaltes Wasser aus einem Hauswasseranschluss, zugeführt wird. Über eine weitere Leitung 59 könnte das Kühlmedium wieder aus der Kühleinheit 20 abgeführt werden.Cold water is fed to a
Nach Ende des Betriebes des Dampfgenerators 1 im Dampferzeuger 10 verbleibendes Wasser wird über eine Entleerleitung 26, die in den Dampfauslass 14 mündet, und ein Entleerventil 24, das durch die Elektrikeinheit 16 angesteuert wird, entleert, wie weiter unten im Detail beschrieben.After the operation of the steam generator 1 in the
Im Dampferzeuger 10 ist, wie in den
In
Der aromatisierte Dampf wird über einen Dampfanschluss 35, an dem die Dampfleitung 15 angeschlossen wird, von der Aromaeinheit abgeführt.In
The aromatized steam is discharged from the aroma unit via a

Die Aromaeinheit 12 kann aber auch noch für andere Zwecke genutzt werden, z.B. für das regelmäßig notwendige Entkalken des Dampferzeugers 10. Dazu wird die Aromaaufnahme 13, wie in
In der Aromaeinheit 12 kann auch ein Führungsmittel 45 angeordnet sein, an dem die Aromaaufnahme 13 zusätzlich geführt wird. Das Führungsmittel 45 kann auch als Anschlag für die Aromaaufnahme 13 dienen, um ein zu weites Herausziehen der Aromaaufnahme 13 aus der Aromaeinheit 12 zu verhindern.In the
In den
Durch die Kühlung der Trennwand 17 wird aber auch das Gehäuse 2 selbst gekühlt, wodurch die Oberflächentemperatur des Gehäuses 2 gesenkt werden kann. Das ermöglicht z.B., dass das Gehäuse 2 auch gefahrlos direkt als Rückenlehne verwendet werden kann.By cooling the
In der Kühleinheit 20 kann auch ein Drucksensor 51 angeordnet sein, der den Wasserdruck in der Ausnehmung 57 misst. Dieser Drucksensor 51 kann für Sicherheitszwecke genutzt werden, um festzustellen, ob überhaupt Wasser vorhanden ist. Sollte kein Wasser vorhanden sein, so darf der Dampferzeuger 10 nicht in Betrieb genommen werden, um Überhitzung des Dampferzeugers 10 zu verhindern.In the
Für eine komfortable Funktion des Dampfgenerators 1, z.B. für den Einsatz in einer Dampfdusche, ist ein gleichmäßiges, unterbrechungsfreies Dampfen wünschenswert. Ein Zusammenfallen des Dampfes soll dabei vermieden werden. Das kann über das Zusammenspiel von Wasserstand im Dampferzeuger 10 und Heizleistung des Heizelements im Dampferzeuger (die üblicherweise konstant ist, aber auch geregelt sein könnte) sichergestellt werden. Dabei darf nicht zu viel kaltes Wasser zugeführt werden, da dann die Leistung des Heizelements unter Umständen nicht mehr ausreichen kann, um unterbrechungsfrei den gewünschten Dampf zu erzeugen. Daher muss sichergestellt sein, dass beim Nachfüllen von Wasser in den Dampferzeuger 10 nur so viel Wasser zugeführt wird, um gleichmäßiges, unterbrechungsfreies Dampfen zu gewährleisten. Dazu wird das Wasser impulsförmig zugeführt.For a comfortable operation of the steam generator 1, e.g. for use in a steam shower, uniform, uninterrupted steaming is desirable. A collapse of the steam should be avoided. This can be ensured by the interaction of water level in the
Die Menge des impulsförmig zugeführten kalten Wasser hängt aber vom Wasserdruck und von der Öffnungszeit des Füllventils 25 ab. Unter kaltem Wasser wird dabei Wasser verstanden, das einem Wasseranschluss, z.B. ein Hauswasseranschluss, entnommen wird und in der Regel Temperaturen von 5°C bis 20°C aufweisen kann [bitte prüfen]. Es wird daher zuerst, z.B. bei der Inbetriebnahme oder bei jedem Einschalten des Dampfgenerators 1, der Wasserdruck gemessen. Dies kann z.B. erfolgen, indem die Zeit gemessen wird, die benötigt wird, den Dampferzeuger 10 bei offenem Füllventil 25 bis zum Ansprechen des Niveausensors 31 zu füllen. Von dieser Füllzeit kann auf den Wasserdruck geschlossen werden, z.B. empirisch durch durchgeführte Versuche und Testreihen oder aufgrund der geometrischen Verhältnisse (Strömungsquerschnitte, Verlustbeiwerte, etc.) berechnet. Alternativ könnte der Wasserdruck auch direkt gemessen werden, z.B. über den Drucksensor 51 in der Kühleinheit 20 oder durch einen beliebig anderswo angeordneten Drucksensor. In Abhängigkeit vom ermittelten Wasserdruck werden Füllimpulse, z.B. definiert durch die Zeiten für Füllen (Füllventil 25 offen) und Nicht-Füllen (Füllventil 25 geschlossen), ermittelt. Die Füllimpulse können z.B. in einer Speichereinheit 28 der Elektrikeinheit 16 einem Druckbereich zugeordnet hinterlegt sein, sodass die Füllimpulse nach Ermittlung des herrschenden Wasserdruckes von einer Steuereinheit 29, die das Füllventil 25 entsprechend ansteuert, abgerufen werden können. Ebenfalls können in Abhängigkeit des ermittelten Wasserdruckes auch die Anzahl der Füllimpulse festgelegt werden. Diese können wiederum dem Wasserdruck zugeordnet in der Speichereinheit 28 hinterlegt sein. Die Anzahl der Füllimpulse könnte aber auch fix festgelegt sein, sodass immer mit der vorgegebenen Anzahl von Füllimpulsen gefüllt wird. Der oben beschriebene Zusammenhang wird anhand der folgenden Tabelle 1 verdeutlicht, wobei in diesem Beispiel der Wasserdruck über die Füllzeit ermittelt wurde.
Ab einem bestimmten ermittelten minimalen Wasserdruck kann von einem Fehler ausgegangen werden und es kann eine entsprechende Fehlermeldung ausgegeben werden, z.B. durch eine blinkende LED oder durch eine Anzeige auf der Bedieneinheit 4. Der Betrieb des Dampfgenerators 1 wird dabei unterbunden bis der Fehler behoben ist.From a certain determined minimum water pressure can be assumed that an error and it can be issued a corresponding error message, e.g. by a flashing LED or by a display on the
Alternativ könnte aber auch ein kontinuierliches Nachfüllen (entspricht einem einzigen Impuls) des Dampferzeugers 10 realisiert sein. Dazu wird die Nachfüllzeit (Füllventil 25 offen) in Abhängigkeit des ermittelten Wasserdruckes festgelegt.Alternatively, however, a continuous refilling (corresponding to a single pulse) of the
Nach dem Ende des Betriebs des Dampfgenerators 1, z.B. indem der Dampfgenerator 1 manuell abgeschaltet wird, befindet sich noch heißes Wasser im Dampferzeuger 10. Dieses heiße Wasser (mit Temperaturen von bis 90°C und mehr) kann aber nicht einfach über das Entleerventil 24 und den Dampfauslass 14 abgelassen werden, da dabei Gefahr für die Verbrühung von Personen besteht und das aus Sicherheitsgründen folglich zu verhindern ist. Es ist daher ein kontrolliertes Entleeren notwendig, um eine maximale Austrittstemperatur des zu entleerenden Wassers (z.B. max. 42°C) zu gewährleisten. Dazu wird während des Entleerens kaltes Wasser beigemengt und mit dem heißen Wasser vermischt. Das kalte Wasser wird vorteilhafter Weise impulsförmig beigemengt, um eine gute Durchmischung mit dem heißen Wasser zu erzielen. Die Mischimpulse werden wiederum vom ermittelten Wasserdruck (wie oben beschrieben) abhängig gemacht. Die Mischimpulse werden in Abhängigkeit vom Wasserdruck entweder über das Füllventil 25 oder das Entleerventil 24 erzeugt, die dazu von der Steuereinheit 29 angesteuert werden. Die Entleerung wird vorzugsweise während einer vorgegebenen Entleerdauer, die ebenfalls vom Wasserdruck abhängig sein kann, durchgeführt. Der oben beschriebene Zusammenhang wird anhand der folgenden Tabelle 2 verdeutlicht, wobei in diesem Beispiel der Wasserdruck über die Füllzeit (siehe oben) ermittelt wurde.
In einem ersten Bereich mit hohem Wasserdruck (kurzer Füllzeit) werden die Mischimpulse über das Füllventil 25 erzeugt und das Entleerventil 24 dauerhaft (während der Entleerdauer) auf offen gestellt. Aufgrund des hohen Wasserdruckes kann so ausreichend kaltes Wasser zugeführt werden, um eine ausreichende Durchmischung zu erzielen , um eine aus Sicherheitsgründen notwendig niedrige Tempertur des ablaufenden Wassers sicherzustellen. In einem zweiten Bereich werden sowohl das Füllventil 25, als auch das Entleerventil 24, dauerhaft geöffnet, da der Wasserdruck für eine permanente Zufuhr von kaltem Wasser und gleichzeitiger Entleerung passend ist. In einem dritten Bereich mit niedrigem Wasserdruck (langer Füllzeit) wird das Füllventil 25 dauerhaft geöffnet und die Mischimpulse über das Entleerventil 24 erzeugt. In diesem Bereich reicht der Wasserdruck nicht aus, um eine ausreichende Durchmischung bei impulsartiger Zufuhr von kaltem Wasser zu gewährleisten. Das kalte Wasser wird daher laufend zugeführt und die Mischung aus heißem Wasser aus dem Dampferzeuger 10 und kaltem Wasser nach einer bestimmten Mischzeit (Entleerventil 24 geschlossen) für eine bestimmte Dauer impulsförmig entleert (Entleerventil 24 offen), um eine aus Sicherheitsgründen notwendig niedrige Tempertur des ablaufenden Wassers sicherzustellen.In a first area with high water pressure (short filling time), the mixing pulses are generated via the filling
Der oben beschriebene Dampfgenerator 1 kann z.B. in einer Dampfdusche 60 verwendet werden, wie in
