Abstract

In order to ensure the best possible heating of the steam generator in a combined steam cleaning and steam iron device with a steam generator in which a supply of water is evaporated by an electric heating element and with a connection on the steam generator to which steam-emitting devices or a smoothing iron can be connected to which steam can be supplied via the connection and a steam pipe, it is proposed that, when a steam iron (8) is connected, the power of the heating element (12, 13) evaporating the water supply is necessarily reduced in relation to the power supplied on the connection of the other steam-emitting devices (7) and at the same time an electrical connection is made between the steam generator (2) and the iron (8), via which electric heating (14) in the iron (8) is supplied.

Description

KOMBINIERTES DAMPFREINIGUNGS- UND DAMPFBÜGELGERÄT COMBINED STEAM CLEANING AND STEAM IRONING UNIT
Die Erfindung betrifft ein kombiniertes Dampfreini- gungs- und Dampfbügelgerät mit einem Dampferzeuger, in dem ein Wasservorrat durch eine elektrische Heizung verdampft wird, und mit einem Anschluß am Dampferzeuger, an den wahl¬ weise Dampfabgabevorrichtungen oder ein Bügeleisen an¬ schließbar sind, denen über den Anschluß und eine Dampflei¬ tung Dampf zuführbar ist.The invention relates to a combined steam cleaning and steam ironing device with a steam generator, in which a water supply is evaporated by an electric heater, and with a connection to the steam generator, to which steam dispensing devices or an iron can be connected, via which the steam generator Connection and a steam line steam can be supplied.
Es sind derartige Dampfreinigungsgeräte bekannt, die mit unterschiedlichem Zubehör betrieben werden können, bei¬ spielsweise mit PunktStrahldüsen, mit Wischköpfen, mit Bür¬ sten oder mit Abstreiflippen, aber auch mit einem Bügelei¬ sen, das durch die Dampfzufuhr zum Dampfbügeleisen wird.Steam cleaning devices of this type are known which can be operated with different accessories, for example with point jet nozzles, with wiping heads, with brushes or with wiping lips, but also with an iron which is made into a steam iron by the steam supply.
Während bei dem übrigen Zubehör keine elektrische Versor¬ gung der Dampfabgabevorrichtung notwendig ist, wird das Dampfbügeleisen durch eine in ihm eingebaute elektrische Heizung beheizt, und dazu ist eine elektrische Versorgung des Dampfbügeleisens notwendig, die üblicherweise vom Dampferzeuger her erfolgt, der ja seinerseits auch elek¬ trisch beheizt ist.While no electrical supply of the steam delivery device is necessary for the other accessories, the steam iron is heated by an electrical heater built into it, and this requires an electrical supply to the steam iron, which is usually provided by the steam generator, which in turn is also electrical is heated trically.
Aufgrund der begrenzten Kapazität des üblicherweise zur Verfügung stehenden elektrischen Leitungsnetzes muß die Wasserheizung immer so dimensioniert werden, daß beim Bü¬ gelbetrieb der Maximalwert der vom Leitungsnetz entnehmba¬ ren Leistung nicht überschritten wird. Dies begrenzt die Verdampfungskapazität des Dampferzeugers.Due to the limited capacity of the usually available electrical network, the Water heating must always be dimensioned so that the maximum value of the power that can be drawn from the mains is not exceeded during ironing. This limits the evaporation capacity of the steam generator.
Es ist Aufgabe der Erfindung, ein kombiniertes Dampfreini- gungs- und Dampfbügelgerät der gattungsgemäßen Art so zu verbessern, daß eine optimale Verdampfung möglich ist.It is an object of the invention to improve a combined steam cleaning and steam ironing device of the generic type in such a way that optimal evaporation is possible.
Diese Aufgabe wird bei einem kombinierten Dampfreini- gungs- und Dampfbügelgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß beim Anschließen eines Bügeleisens zwangsläufig die Leistung der den Wasservorrat verdampfenden Heizung gegenüber der Leistung beim Anschluß der anderen Dampfabgabevorrichtungen reduziert ist und gleichzeitig eine elektrische Verbindung zwischen Dampfer¬ zeuger und Bügeleisen hergestellt ist, über die eine elek¬ trische Heizung im Bügeleisen versorgt wird.This object is achieved according to the invention in a combined steam cleaning and steam ironing device of the type described at the outset in that when an iron is connected, the power of the heating evaporating the water supply is inevitably reduced compared to the power when the other steam delivery devices are connected, and at the same time an electrical connection between the steamers ¬ generator and iron is produced, via which an electric heater in the iron is supplied.
Es wird also durch die Herstellung des Anschlusses zwischen dem Dampferzeuger und dem Bügeleisen einerseits oder den übrigen Dampfabgabevorrichtungen andererseits die Heizung im Dampferzeuger so beeinflußt, daß sie beim Anschluß der selbst keine elektrische Energie benötigenden Dampfabgabe¬ vorrichtungen mit höherer Leistung arbeitet als beim An¬ schluß eines Bügeleisens. Dadurch kann die vom Versorgungs¬ netz zur Verfügung gestellte elektrische Leistung voll aus¬ genutzt werden.It is thus influenced by the production of the connection between the steam generator and the iron on the one hand or the other steam delivery devices on the other hand that the heating in the steam generator is such that when the steam delivery devices themselves, which do not require any electrical energy, they operate at a higher power than when connecting one Iron. As a result, the electrical power made available by the supply network can be fully utilized.
Eine Möglichkeit besteht dabei darin, daß die elektrische Heizung im Dampferzeuger zwei Heizelemente umfaßt, von de¬ nen eines abgeschaltet wird, wenn ein Bügeleisen an den Dampferzeuger angeschlossen ist. Dabei wird also nur beim Anschluß eines Bügeleisens die Heizleistung des Dampferzeu¬ gers vermindert, in allen übrigen Phasen, also beim An¬ schluß einer der übrigen Dampfabgabevorrichtungen oder bei fehlendem Anschluß wird jedoch die elektrische Heizung im Dampferzeuger mit voller Leistung betrieben.One possibility is that the electric heater in the steam generator comprises two heating elements, one of which is switched off when an iron is connected to the Steam generator is connected. The heating power of the steam generator is thus reduced only when an iron is connected, but in all other phases, ie when one of the other steam delivery devices is connected or when there is no connection, the electric heating in the steam generator is operated at full power.
Bei einer anderen Möglichkeit ist vorgesehen, daß die elek¬ trische Heizung im Dampferzeuger zwei Heizelemente umfaßt, die nur gemeinsam eingeschaltet sind, wenn eine der übrigen Dampfabgabevorrichtungen an den Dampferzeuger angeschlossen ist. Bei dieser Lösung wird also nur mit voller Leistung verdampft, wenn an dem Dampferzeuger eine Dampfabgabevor- richtung angeschlossen ist, die selber keine elektrische Energie verbraucht. Wenn das Bügeleisen angeschlossen ist und wenn keine Dampfabgabevorrichtung angeschlossen ist, wird nur mit geringerer Leistung verdampft, man erhält ins¬ besondere bei nicht angeschlossenen Dampfabgabevorrichtun¬ gen dann einen Sparbetrieb des Dampferzeugers, der diesen dann zwar in Betriebsbereitschaft hält, aufgrund des feh¬ lenden Dampfverbrauches aber nur mit geringerer Leistung heizt.Another possibility provides that the electric heater in the steam generator comprises two heating elements which are only switched on together when one of the other steam delivery devices is connected to the steam generator. With this solution, vaporization is only carried out at full power if a steam delivery device is connected to the steam generator which does not itself consume any electrical energy. If the iron is connected and if no steam delivery device is connected, the steam is evaporated only at a lower power, in particular if steam delivery devices are not connected, the steam generator is then operated economically, which then keeps it ready for operation because of the lack of steam consumption but only heats with less power.
Bei einer bevorzugten Ausführungsform ist vorgesehen, daß der Anschluß einen Stecker und eine Buchse mit mehreren elektrischen Kontakten umfaßt, die beim Bügeleisen einer¬ seits und bei den übrigen Dampfabgabevorrichtungen anderer¬ seits so verschieden belegt sind, daß nur beim Anschluß des Bügeleisens die Heizung im Dampferzeuger mit reduzierter Leistung arbeitet. Während es also grundsätzlich möglich ist, die Umschaltung der Leistungsaufnahme der Heizung im Dampferzeuger mit den unterschiedlichsten Mitteln zu errei- chen, beispielsweise durch mechanisch betätigte Kontakte bei der Herstellung des Anschlusses, wird hier eine elek¬ trische Lösung vorgeschlagen, bei der durch Herstellung des Kontaktes, also durch Herstellung der Steckverbindung, die elektrischen Verbindungen so geschaltet werden, daß automa¬ tisch die Leistung der Heizung im Dampferzeuger entspre¬ chend dem jeweils angeschlossenen Zubehörteil variiert wird.In a preferred embodiment it is provided that the connection comprises a plug and a socket with a plurality of electrical contacts which on the one hand are so differently used in the iron and on the other hand in the other steam dispensing devices that the heating in the steam generator is connected only when the iron is connected works with reduced power. While it is basically possible to switch the power consumption of the heating in the steam generator with a wide variety of means Chen, for example by mechanically actuated contacts during the production of the connection, an electrical solution is proposed here, in which the electrical connections are switched so that the power of the heating is automatically switched by the production of the contact, that is to say the production of the plug connection is varied in the steam generator according to the connected accessory.
Es ist vorteilhaft, wenn der Anschluß weitere elektrische Kontakte aufweist, durch die eine an der Dampfabgabevor¬ richtung oder am Bügeleisen aktivierbare Steuerleitung zu Schaltelementen im Dampferzeuger führt. Man kann dann an der Dampfabgabevorrichtung oder am Bügeleisen Funktionen im Dampferzeuger steuern, beispielsweise die Dampfzufuhr.It is advantageous if the connection has further electrical contacts through which a control line, which can be activated on the steam delivery device or on the iron, leads to switching elements in the steam generator. You can then control functions in the steam generator, for example the steam supply, on the steam delivery device or on the iron.
Dabei ist insbesondere vorgesehen, daß das Bügeleisen und die übrigen Dampfabgabevorrichtungen verschiedene elektri¬ sche Kontakte für die Steuerleitung im Anschluß belegen, so daß unterschiedliche Schaltelemente im Dampferzeuger betä¬ tigbar sind. Beispielsweise kann das von der Steuerleitung im Dampferzeuger betätigbare Schaltelement beim Bügeleisen ein Schließventil mit Dampfmengenregulierung sein, bei den übrigen Dampfabgabevorrichtungen dagegen ein Schließventil ohne Dampfmengenregulierung.In particular, it is provided that the iron and the other steam delivery devices occupy different electrical contacts for the control line in the connection, so that different switching elements in the steam generator can be actuated. For example, the switching element which can be actuated by the control line in the steam generator can be a closing valve with steam quantity regulation in the iron, whereas a closing valve without steam quantity regulation can be used in the other steam delivery devices.
Vorteilhaft ist es weiterhin, wenn in den einen Stecker und eine Buchse umfassenden Anschluß auch die Dampfleitung in¬ tegriert ist. Dadurch wird durch Zusammenfügen dieser bei¬ den Teile des Anschlusses eine vollständige Verbindung hin¬ sichtlich aller Funktionen ermöglicht, es wird also die Um¬ schaltung der Heizleistung im Dampferzeuger vorgenommen, die Verbindung mit Schaltelementen und die Verbindung der Dampfzufuhr.It is also advantageous if the steam line is also integrated into the connection comprising a plug and a socket. As a result, by joining these two parts of the connection, a complete connection with regard to all functions is made possible, that is, the heating power is switched over in the steam generator, the connection with switching elements and the connection of the steam supply.
Die nachfolgende Beschreibung einer bevorzugten Ausfüh¬ rungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of a preferred embodiment of the invention serves in conjunction with the drawing to provide a more detailed explanation. Show it:

In einem fahrbaren Gehäuse 1 ist ein Dampferzeuger 2 unter¬ gebracht, der einen in der Zeichnung nicht eigens darge¬ stellten Wassertank und eine elektrische Heizung umfaßt, die das Wasser im Wassertank verdampft. Der Dampferzeuger 2 weist einen Anschluß 3 in Form einer Steckbuchse 4 auf, an den ein Stecker 5 angeschlossen werden kann, der über eine Leitung 6 mit einer Dampfabgabevorrichtung verbunden ist, im dargestellten Beispiel mit einem Wischkopf 7. Dieser Wischkopf könnte auch durch ein Strahlrohr oder eine belie¬ bige andere Vorrichtung ersetzt werden, durch die Dampf ab- gegeben werden soll, es gibt dafür in der Regel mehrere Dampfabgabevorrichtungen, die wahlweise an den Anschluß 3 angeschlossen werden können.In a mobile housing 1, a steam generator 2 is accommodated, which comprises a water tank (not specifically shown in the drawing) and an electric heater that evaporates the water in the water tank. The steam generator 2 has a connection 3 in the form of a socket 4, to which a plug 5 can be connected, which is connected via a line 6 to a steam delivery device, in the example shown with a wiper head 7. This wiper head could also be through a jet pipe or any other device can be replaced by which steam should be given, there are usually several steam delivery devices that can optionally be connected to port 3.
Ebenfalls an den Dampferzeuger 2 anschließbar ist ein Bü¬ geleisen 8, das ebenfalls über eine Leitung 6 und einen Stecker 5 verfügt.An iron 8, which also has a line 6 and a plug 5, can also be connected to the steam generator 2.
Stecker 5 und Steckbuchse 4 beinhalten einmal eine Verbin¬ dungsmöglichkeit einer Dampfleitung, zum anderen verfügen sie über eine Anzahl von elektrischen Kontakten, durch die mehrere parallele elektrische Verbindungen hergestellt wer¬ den können. Im folgenden wird davon ausgegangen, daß sechs derartige elektrische Kontakte zur Verfügung stehen, selbstverständlich ist auch eine beliebige andere Anzahl möglich.Plug 5 and socket 4 contain a connection possibility of a steam line, on the other hand they have a number of electrical contacts through which several parallel electrical connections can be made. In the following it is assumed that six such electrical contacts are available, of course any other number is also possible.
Die elektrische Ausgestaltung des beschriebenen Gerätes wird im folgenden anhand der Figuren 2 bis 4 erörtert, wo¬ bei bei der Darstellung der Figuren 3 und 4 nur die elek¬ trischen Kontakte des Anschlusses 3 dargestellt sind, nicht dagegen der ebenfalls integrierte Dampfleitungsanschluß.The electrical configuration of the device described is discussed below with reference to FIGS. 2 to 4, wherein only the electrical contacts of connection 3 are shown in the representation of FIGS. 3 and 4, but not the steam line connection, which is likewise integrated.
Der Dampferzeuger 2 wird über eine externe elektrische Ver¬ sorgungsleitung mit einer Spannungsquelle verbunden, diese Leitung ist in Figur 1 nicht dargestellt. In der elektri¬ schen Skizze der Figur 2 werden die beiden Zweige 9, 10 der Versorgungsleitung mit den Buchstaben L und N gekennzeich¬ net.The steam generator 2 is connected to a voltage source via an external electrical supply line, this line is not shown in FIG. 1. In the electrical sketch of FIG. 2, the two branches 9, 10 of the supply line are identified with the letters L and N.
Über einen zweipoligen Einschalter 11 werden die Zweige 9 und 10 mit den Enden eines Heizelementes 12 verbunden, wel- ches den Wasservorratstank im Dampferzeuger 2 erhitzt und somit Wasser verdampft.The branches 9 and 10 are connected to the ends of a heating element 12 via a two-pole switch 11, which ches the water storage tank in the steam generator 2 heated and thus evaporates water.
Parallel zum Heizelement 12 ist ein zweites Heizelement 13 geschaltet, dessen Versorgungsleitung jedoch zu den Kontak¬ ten D und E der Steckbuchse 4 führt und dort unterbrochen ist. Nur beim Schließen dieser Unterbrechung zwischen den Kontakten D und E wird das Heizelement 13, das ebenfalls den Wasservorratsbehälter beheizt, aktiviert. Die beiden Heizelemente 12 und 13 bilden also gemeinsam die Verdamp¬ ferheizung, sie sind jedoch nicht zwangsläufig immer ge¬ meinsam aktiviert.A second heating element 13 is connected in parallel to the heating element 12, but its supply line leads to the contacts D and E of the socket 4 and is interrupted there. The heating element 13, which also heats the water reservoir, is only activated when this interruption between the contacts D and E is closed. The two heating elements 12 and 13 thus together form the evaporator heater, but they are not necessarily always activated together.
Wie sich aus der Darstellung der Figuren 3 und 4 ergibt, hat nur der Stecker der übrigen Dampfabgabegeräte eine sol¬ che elektrische Brücke zwischen den Kontakten D und E, nicht jedoch der Stecker des Bügeleisens (Figur 3). Dies bedeutet, daß das zweite Heizelement 13 nur dann aktiviert wird, wenn ein Zubehörteil an den Dampferzeuger angeschlos¬ sen ist, welches selber nicht mit elektrischer Energie ver¬ sorgt werden muß.As can be seen from the illustration in FIGS. 3 and 4, only the plug of the other steam delivery devices has such an electrical bridge between the contacts D and E, but not the plug of the iron (FIG. 3). This means that the second heating element 13 is only activated when an accessory is connected to the steam generator which does not itself have to be supplied with electrical energy.
Im Stecker des Bügeleisens sind die Kontakte E und F über ein Heizelement 14 miteinander verbunden, dieses Heizele¬ ment 14 befindet sich im Bügeleisen 8. Wenn der Stecker des Bügeleisens in die Steckbuchse 4 eingesteckt wird, ergibt sich über die Kontakte E und F des Dampferzeugers 2 eine Verbindung der Kontakte E und F des Steckers mit den beiden Zweigen 9 beziehungsweise 10 der Spannungsquelle, da der Kontakt F der Steckbuchse 4 über eine Leitung 15 und einen Zubehörschalter 16 mit dem Zweig 9 der Versorgungsleitung in Verbindung steht, der Kontakt E ist direkt mit dem Zweig 10 der Versorgungsleitung verbunden. Damit ergibt sich eine Beheizung des Bügeleisens, sobald die Verbindung herge¬ stellt ist. Günstig ist es, wenn die Leistung des Heizele¬ mentes 14 der des Heizelementes 13 entspricht, es ist dann möglich, insgesamt immer die optimal vom Netz zur Verfügung gestellte Leistung auszunützen, sei es zum starken Verdamp¬ fen im Dampferzeuger bei Betrieb eines Zubehörteils ohne elektrische Versorgung oder sei es beim Verdampfen mit re¬ duzierter Leistung und gleichzeitiger Beheizung des Bügel¬ eisens.In the plug of the iron, the contacts E and F are connected to one another via a heating element 14, this heating element 14 is located in the iron 8. When the plug of the iron is inserted into the socket 4, the contacts E and F of the steam generator result 2 a connection of the contacts E and F of the plug to the two branches 9 and 10 of the voltage source, since the contact F of the socket 4 is connected to the branch 9 of the supply line via a line 15 and an accessory switch 16, the contact E is direct with the branch 10 connected to the supply line. This results in heating of the iron as soon as the connection is established. It is expedient if the power of the heating element 14 corresponds to that of the heating element 13, it is then possible overall to always utilize the power optimally made available by the network, be it for vaporizing strongly in the steam generator when operating an accessory without electrical Supply or be it with evaporation with reduced power and simultaneous heating of the iron.
Die Zweige 9, 10 der Versorgungsleitung sind über den Zube¬ hörschalter 16 mit einem Spannungswandler 17 verbunden, dessen Sekundärseite einerseits mit dem Kontakt A und ande¬ rerseits über zwei parallele Leitungen 18, 19 mit den Kon¬ takten C beziehungsweise B der Steckbuchse 4 in Verbindung steht. In die Leitung 18 ist ein Magnetventil 20 einge¬ setzt, das bei Stromfluß öffnet und sonst geschlossen ist, in die Leitung 19 ein Magnetventil 21 mit Dosiervorrich¬ tung, welches ebenfalls bei Stromfluß öffnet und sonst ge¬ schlossen ist. Die Dosierung des Magnetventils 21 kann bei¬ spielsweise durch einen Drehknopf 22 an der Oberseite des Dampferzeugers 2 erfolgen (Figur 1).The branches 9, 10 of the supply line are connected via the accessory switch 16 to a voltage converter 17, the secondary side of which is connected on the one hand to the contact A and on the other hand via two parallel lines 18, 19 to the contacts C and B of the socket 4 in Connection is established. A solenoid valve 20 is inserted in line 18, which opens when the current flows and is otherwise closed, in line 19 a solenoid valve 21 with a metering device, which also opens when the current flows and is otherwise closed. The solenoid valve 21 can be metered, for example, by means of a rotary knob 22 on the upper side of the steam generator 2 (FIG. 1).
Im Bügeleisen sind die Kontakte A und B über einen Druck¬ schalter 23 miteinander verbunden, so daß diese Verbindung bei Betätigung des Druckschalters herstellbar ist. Durch Betätigung des Druckschalters 23 wird also das Magnetventil mit Dosierung geöffnet, Dampf strömt dann mit der am Dreh¬ knopf 22 eingestellten Menge zum Bügeleisen. Im Stecker der übrigen Dampfabgabevorrichtungen sind die Kontakte A und C über einen Druckschalter 24 miteinander verbunden, auch dieser schließt die Verbindung bei Betäti¬ gung. Von diesen Geräten aus kann also durch Betätigung des Druckschalters 24 das Magnetventil 20 geöffnet werden, so daß dann Dampf in voller Menge der Dampfabgabevorrichtung zugeführt wird.In the iron, contacts A and B are connected to one another via a pressure switch 23, so that this connection can be established when the pressure switch is actuated. By actuating the pressure switch 23 the solenoid valve is opened with metering, steam then flows to the iron with the amount set on the rotary knob 22. In the plug of the other steam delivery devices, the contacts A and C are connected to one another via a pressure switch 24 connected, this also closes the connection when actuated. From these devices, the solenoid valve 20 can thus be opened by actuating the pressure switch 24, so that steam is then supplied in full to the steam delivery device.
Der Kontakt C ist beim Bügeleisen nicht belegt, der Kontakt B dagegen bei den übrigen Dampfabgabevorrichtungen nicht. Somit wird selektiv durch den Anschluß der unterschiedli¬ chen Zubehörteile festgelegt, welches Steuerelement im Dampferzeuger bei Betätigung des Druckschalters angesteuert wird, also das lediglich öffnende und schließende Magnet¬ ventil 20 oder das Magnetventil 21 mit Dosiervorrichtung. Contact C is not used for the iron, but contact B is not used for the other steam delivery devices. Thus, by connecting the different accessories, it is selectively determined which control element in the steam generator is actuated when the pressure switch is actuated, that is to say the solenoid valve 20 that only opens and closes or the solenoid valve 21 with the metering device.
