Description

Die Erfindung betrifft ein Dampfreinigunsgerät mit einem zur Verdampfung beheizten Wasservorratsbehälter, einer aus dem Dampfraum des Wasservorratsbehälters austretenden Dampfleitung, die zu einem Dampfabgabeorgan führt und in der ein Schließ- oder Dosierventil angeordnet ist, und mit einer in die Dampfleitung eintretenden Zufuhr für flüssiges Wasser.The invention relates to a steam cleaning device with a water storage tank heated for evaporation, one emerging from the vapor space of the water reservoir Steam line leading to a steam delivery device leads and arranged in a closing or metering valve and with one entering the steam line Liquid water supply.

Dampfreinigungsgeräte dieser Art werden zunehmend auch im privaten Bereich eingesetzt, um ohne Verwendung von Chemikalien eine wirksame Reinigung von Gegenständen und Flächen zu ermöglichen. Die Reinigung ist dabei außerordentlich effektiv, da aufgrund der hohen Temperatur des auftreffenden Dampfes ein hoher Lösungseffekt auftritt.Steam cleaners of this type are becoming increasingly popular used in the private sector to use without Chemicals an effective cleaning of objects and enable areas. The cleaning is extraordinary effective because of the high temperature a high dissolving effect of the impinging steam occurs.

In Einzelfällen kann es zur Erhöhung des Reinigungseffektes sinnvoll sein, dem Dampfstrahl in geringem Umfange flüssiges Wasser zuzugeben, um dadurch die Reinigungswirkung zu verbessern.In some cases it can increase the cleaning effect be useful, the steam jet to a small extent add liquid water to improve the cleaning effect to improve.

So ist es beispielsweise bekannt, bei Bedarf aus einer den Wasservorratsbehälter auffüllenden Versorgungsleitung einen Wasserstrom in die Dampfleitung abzuzweigen (DE 92 08 614 U).So it is known, for example, from a supply line filling the water reservoir to branch a stream of water into the steam pipe (DE 92 08 614 U).

Abgesehen davon, daß dafür ein relativ hoher apparativer Aufwand notwendig ist, ist die Reinigungswirkung nicht in allen Fällen befriedigend. Apart from the fact that a relatively high apparatus The cleaning effect is necessary not satisfactory in all cases.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Dampfreinigungsgerät so auszugestalten, daß die Reinigungswirkung bei Bedarf durch Zugabe von flüssigem Wasser verbessert werden kann.It is an object of the invention, a generic Steam cleaning device so that the cleaning effect if necessary by adding liquid water can be improved.

Diese Aufgabe wird beim Dampfreinigungsgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Zufuhr durch eine in den Wasserraum des Wasservorratsbehälters eintauchende Steigleitung gebildet wird, daß in die Zufuhr ein Dosier- oder Schließventil eingefügt ist und daß die Zufuhr stromaufwärts des Schließ- oder Dosierventils in der Dampfleitung in diese einmündet.This task is the beginning of the steam cleaning device described type solved according to the invention, that the supply through a in the water space of the water reservoir immersed riser formed is that in the feed a metering or closing valve is inserted and that the feed upstream of the Closing or dosing valve in the steam line in this flows into.

Diese Ausgestaltung führt dazu, daß das in die Dampfleitung eingeführte flüssige Wasser aus dem Wasservorratsbehälter entnommen wird. Dieses Wasser ist somit heiß, und bereits aus diesem Grunde ergibt sich eine wesentlich verbesserte Reinigungswirkung. Während bei der Zugabe von kaltem Wasser zum Dampf bereits in der Durchmischungsstrecke eine so starke Kondensation des Wasserdampfes eintreten kann, daß kaum mehr Dampf auf die zu reinigende Fläche auftrifft, wird diese Wirkung bei der Verwendung von heißem Wasser vermieden. Der auftreffende Reinigungsmittelstrahl besteht weiterhin zum überwiegenden Teil aus Wasserdampf, dem nur in geringem Umfange flüssiges Wasser zugefügt ist.This configuration leads to the fact that in the steam line imported liquid water from the water reservoir is removed. So this water is hot, and for this reason alone significantly improved cleaning effect. While at the addition of cold water to the steam already in the Mixing section such a strong condensation of the Water vapor can enter that little more steam the surface to be cleaned hits this effect avoided when using hot water. Of the impinging jet of cleaning agent continues to exist Mostly from water vapor, but only to a small extent Lots of liquid water is added.

Ein weiterer Vorteil der beschriebenen Konstruktion liegt darin, daß der Benutzer von einer Verbindung mit der Wasserversorgung während des Betriebes unabhängig ist. Das flüssige Wasser wird ebenso dem Wasservorratsbehälter entnommen wie der Wasserdampf, so daß auch bei dem tragbaren und nicht mit einer Wasserquelle verbundenen Dampfreinigungsgerät beide Betriebsarten ohne weiteres durchgeführt werden können.Another advantage of the construction described is that the user is disconnected from independent of the water supply during operation is. The liquid water also becomes the water reservoir taken as the water vapor, so that also at the portable one and not connected to a water source Steam cleaning device both operating modes without further can be carried out.

Schließlich ergibt sich durch die Verwendung der Steigleitung ein besonders einfacher Aufbau, gegebenenfalls können die Steigleitung und die Dampfleitung durch eine gemeinsame Öffnung an der Oberseite des Wasservorratsbehälters aus diesem herausgeführt werden, daher kann eine solche Vorrichtung auch an bereits vorhandenen Wasservorratsbehältern ohne Konstruktionsänderung eingesetzt werden.Finally, the use of the riser results a particularly simple structure, if necessary can the riser and the steam line through a common opening at the top of the water reservoir can be led out of this, therefore such a device also on existing ones Water storage tanks used without design changes will.

Bei der beschriebenen Konstruktion ist weiterhin sichergestellt, daß bei Erzeugung eines Reinigungsmittelstrahls in jedem Fall ein Dampfstrahl erzeugt wird, dem gegebenenfalls flüssiges Wasser zugemischt ist. Es ist nicht, wie bei anderen Reinigungsgeräten dieser Art, möglich, bei unsachgemäßer Öffnung der Schließ- oder Dosierventile einen reinen Flüssigkeitsstrahl zu erzeugen. Dessen Reinigungswirkung wäre ungenügend, andererseits würde bei Erzeugung eines reinen Flüssigkeitsstrahls der Wasservorrat sehr schnell erschöpft, d.h. die Abgabe wäre insgesamt wirkungslos und unerwünscht. Dies kann bei dem Dampfreinigungsgerät der vorbeschriebenen Art nicht eintreten, da beim Öffnen des Schließ- oder Dosierventils in der Dampfleitung in jedem Fall Dampf austritt. Bleibt dieses Schließ- oder Dosierventil in der Dampfleitung geschlossen, kann auch kein Flüssigkeitsstrahl austreten, wenn in diesem Zustand irrtümlicherweise das Dosier- oder Schließventil in der Flüssigkeitzufuhr geöffnet würde. The construction described also ensures that when generating a detergent jet in any case, a steam jet is generated, which if necessary, liquid water is added. It is not like other cleaning devices of this type, possible with improper opening of the closing or Dosing valves to produce a pure jet of liquid. Its cleaning effect would be insufficient, on the other hand would produce a pure jet of liquid the water supply is exhausted very quickly, i.e. the levy would be ineffective and undesirable overall. This can be the case with the steam cleaning device described above Kind do not occur because when opening the closing or Dosing valve in the steam line in any case Steam escapes. This closing or metering valve remains closed in the steam line, neither can Liquid jet will leak if in this condition erroneously the dosing or closing valve in the Liquid supply would be opened.

Die Entnahme des flüssigen Wassers aus dem Wasservorratsbehälter hat außerdem den Vorteil, daß eine Flüssigkeitsentnahme nur eintreten kann, wenn die Dampferzeugung bereits in genügendem Umfange eingesetzt hat, denn die Förderung des flüssigen Wassers durch die Steigleitung erfolgt unter dem Druck des Dampfes im Dampfraum, und dieser Druck baut sich beim Aufheizen des Wasservorratsbehälters erst allmählich auf. Wenn er jedoch aufgebaut ist, ist in jedem Fall sichergestellt, daß eine ausreichende Dampfabgabe möglich ist, d.h. eine Flüssigkeitsabgabe erfolgt nur dann, wenn auch die Dampfabgabe sichergestellt ist. Auch dadurch sind Fehlbedienungen ausgeschlossen.The removal of the liquid water from the water reservoir also has the advantage that a liquid withdrawal can only occur when the steam generation has already started to a sufficient extent, because the promotion of liquid water through the Riser pipe takes place under the pressure of the steam in the Steam room, and this pressure builds up when it heats up of the water reservoir only gradually. If he however, it is ensured in any case that sufficient steam delivery is possible, i.e. a Liquid is only dispensed if the Steam delivery is ensured. This is also an incorrect operation locked out.

Vorteilhaft ist es, wenn im Einmündungsbereich der Zufuhr in die Dampfleitung der Dampfstrom senkrecht in den Flüssigkeitsstrom eintritt. Es hat sich überraschenderweise herausgestellt, daß dadurch eine besonders wirksame Durchmischung des Mediums in den beiden Aggregatzuständen erreicht wird. Die flüssigen Partikel werden aufgerissen und gleichmäßig im Dampfstrom verteilt, so daß ein Naßdampfstrom erzeugt wird, nicht ein Trockendampfstrom mit eingelagerten Wassertröpfchen.It is advantageous if in the mouth area of the feed into the steam pipe the steam flow vertically in the liquid flow enters. It has surprisingly turned out to be pointed out that this makes a special effective mixing of the medium in the two Physical states is reached. The liquid particles are torn open and distributed evenly in the steam flow, so that a wet steam flow is generated, not a Dry steam flow with embedded water droplets.

Dies kann insbesondere dadurch erreicht werden, daß die Dampfleitung ein T-förmiges Leitungsstück aufweist, an dessen einmündendem Teil die aus dem Dampfraum austretende Dampfleitung und an dessen durchgehendem Teil einerseits die Zufuhr des flüssigen Wassers und andererseits die zum Dampfabgabeorgan weiterführende Dampfleitung angeschlossen sind.This can be achieved in particular that the Steam line has a T-shaped line piece the confluent part of which emerges from the steam room Steam pipe and on its continuous part on the one hand the supply of liquid water and on the other hand the steam line leading to the steam delivery element are connected.

Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß das Dosier- oder Schließventil in der Zufuhr des flüssigen Wassers durch ein Drucktastenventil gebildet ist, welches gegen die Wirkung einer Feder in die Offenstellung bewegbar ist. Dieses Ventil ist also normalerweise geschlossen, so daß im normalen Betrieb nur ein Trockendampfstrom abgegeben wird. Nur für den Fall, daß eine speziell verstärkte Reinigungswirkung notwendig ist, kann der Benutzer die Zugabe von flüssigem Wasser dadurch erreichen, daß er das Drucktastenventil entgegen der Wirkung der Feder bedient, und diese Zugabe wird sofort beendet, sobald der Benutzer das Ventil wieder losläßt. Dies trägt insbesondere dazu bei, im Betrieb Wasser zu sparen und die Betriebsdauer dadurch zu verlängern. In der Praxis ist eine Reinigung mit Trockendampf in den meisten Fällen vollständig ausreichend, nur für ganz extreme Verschmutzungen ist es sinnvoll, kurzzeitig die Reinigungswirkung durch Zugabe des flüssigen Wassers zu erhöhen.In a preferred embodiment of the invention provided that the metering or closing valve in the Liquid water supply through a push button valve is formed, which acts against the action of a spring is movable into the open position. This valve is So normally closed, so that in normal operation only a dry steam flow is emitted. Only for the case that a specially enhanced cleaning effect is necessary, the user can add reach liquid water by pressing the push button valve operated against the action of the spring, and this addition stops immediately as soon as the user releases the valve. This contributes in particular when saving water during operation and the operating time thereby lengthening. In practice there is a cleaning with dry steam completely sufficient in most cases, it is only for very extreme soiling useful, briefly the cleaning effect by adding of the liquid water to increase.

Günstig ist es, wenn das Dosier- oder Schließventil als stufenloses Regelventil ausgebildet ist.It is favorable if the metering or closing valve as stepless control valve is formed.

The following description of a preferred embodiment of the invention serves in conjunction with the drawing for a more detailed explanation. It shows:
Fig. 1
a schematic sketch of the steam cleaning device with addition for liquid water and
Fig. 2
2 shows a cross-sectional view of a water storage container with a riser pipe for use in a steam cleaning device according to FIG. 1.

Das Dampfreinigungsgerät umfaßt einen Wasservorratsbehälter 1, der teilweise mit Wasser gefüllt wird, so daß sich ein von flüssigem Wasser gefüllter Wasserraum 2 und ein oberhalb des Wasserspiegels 3 liegender Dampfraum 4 ergeben. Im Wasserraum 2 befindet sich eine Heizung 5, die das Wasser soweit aufheizt, daß im Dampfraum 4 Wasserdampf unter erhöhtem Druck entsteht, beispielsweise kann die Temperatur im Inneren des Wasservorratsbehälters auf 130 C erhöht werden.The steam cleaner includes a water reservoir 1, which is partially filled with water, so that a water space filled with liquid water 2 and a steam room located above the water level 3 4 result. There is a heater in water room 2 5, which heats the water so far that in the steam room 4 Water vapor is generated under increased pressure, for example can be the temperature inside the water reservoir can be increased to 130 C.

Aus dem Dampfraum 4 führt eine Dampfleitung 6 zu einem in der Zeichnung nicht dargestellten Abgabeorgan, beispielsweise zu einem Sprührohr oder einem Mischkopf, in die Dampfleitung 6 ist ein Schließventil 7 eingeschaltet, das vorzugsweise an dem Dampfabgabeorgan selbst angeordnet sein kann.A steam line 6 leads from the steam chamber 4 to one Not shown in the drawing organ, for example to a spray tube or a mixing head, in the steam line 6, a closing valve 7 is switched on, preferably on the steam delivery member itself can be arranged.

Im Inneren des Wasservorratsbehälters 1 ist ein bis tief in den Wasserraum 2 eintauchendes Steigrohr 8 vorgesehen, welches mit einer Flüssigkeitszufuhrleitung 9 in Verbindung steht, die ihrerseits stromaufwärts des Schließventils 7 in die Dampfleitung 6 einmündet. Diese Einmündung ist in der Zeichnung nur schematisch dargestellt, tatsächlich erfolgt diese vorzugsweise so, daß der Dampfstrom in der Dampfleitung senkrecht auf einen Flüssigkeitsstrom in der Flüssigkeitszufuhrleitung auftrifft. Zu diesem Zweck kann beispielsweise im Bereich der Einmündung der Flüssigkeitszufuhrleitung 9 ein T-förmiges Leitungsstück vorgesehen werden, in dessen einmündendes Teil die mit dem Dampfraum 4 in Verbindung stehende Dampfleitung6 einmündet, während an das durchgehende Teil an einer Seite die Flüssigkeitszufuhrleitung9 angeschlossen ist, an der anderen Seite die zum Dampfabgabeorgan führende Dampfleitung 6. Inside the water reservoir 1 is a to riser pipe 8 immersed deep in the water space 2, which with a liquid supply line 9 connected, which in turn upstream of the Closing valve 7 opens into the steam line 6. This Confluence is only shown schematically in the drawing, in fact, this is preferably done in such a way that the steam flow in the steam line perpendicular to one Liquid flow hits the liquid supply line. For this purpose, for example, in the area the mouth of the liquid supply line 9 is a T-shaped Line piece are provided in the opening part with the steam chamber 4 in connection standing steam line 6 opens while the continuous Part of the liquid supply line on one side 9 is connected on the other side to the Steam delivery device leading steam line 6.

In die Flüssigkeitszufuhrleitung 9 ist ein Dosier- oder Schließventil 10 eingesetzt, das im dargestellten Ausführungsbeispiel durch ein Tastenventil gebildet wird, welches von einer Drucktaste 11 zu betätigen ist. Diese befindet sich an der Außenseite eines der Wasservorratsbehälter 1 umgebenden Gehäuses 12 des Dampfreinigunsgsgerätes und ist gegen die Wirkung einer Feder, die in der Zeichnung nicht dargestellt ist, eindrückbar. Beim Eindrücken wird das Dosier- oder Schließventil 10 geöffnet, d.h. beim Loslassen der Drucktaste 11 geht dieses Ventil zwangsläufig in die Schließstellung über. Das Dosier- oder Schließventil 10 kann vorzugsweise ein stufenloses Regelventil sein, so daß die Flüssigkeitsabgabe in den Dampfstrahl dosiert werden kann.In the liquid supply line 9 is a metering or Closing valve 10 used, that in the illustrated embodiment is formed by a button valve which is to be actuated by a pushbutton 11. This is located on the outside of one of the water storage tanks 1 surrounding housing 12 of the steam cleaning device and is against the action of a spring, which is not shown in the drawing, can be pressed in. When pressed in, the dosing or closing valve 10 open, i.e. when you release the push button 11 this valve inevitably goes into the closed position about. The metering or closing valve 10 can preferably be a continuously variable control valve, so that the Liquid release can be dosed into the steam jet can.

Im Betrieb wird daher bei normalem Reinigungsbedarf und nichtbetätigter Drucktaste 11 Dampf aus dem Dampfraum 4 über die Dampfleitung 6 und über das geöffnete Schließ ventil 7 an das Dampfabgabeorgan geleitet und von dort in Form eines Trockendampfstrahles abgegeben.In operation, therefore, with normal cleaning needs and Non-actuated push button 11 steam from the steam room 4 via the steam line 6 and the open closing valve 7 passed to the steam delivery member and from there emitted in the form of a dry steam jet.

Ergibt sich ein erhöhter Reinigungsbedarf, so kann der Benutzer durch Druck auf die Drucktaste 11 kurzzeitig die Flüssigkeitszufuhrleitung 9 öffnen, und dies führt dazu, daß durch den hohen Druck des Dampfes im Dampfraum 4 heißes Wasser aus dem Wasserraum 2 durch das Steigrohr 8 in die Flüssigkeitszufuhrleitung 9 gedrückt wird. In diesen kurzzeitigen Flüssigkeitsstrom tritt der Dampf aus der Dampfleitung 6 ein und bildet dadurch eine homogene Naßdampfmischung, die dann über das Schließventil 7 dem Dampfabgabeorgan zugeführt wird. Es ist damit möglich, durch Druck auf die Drucktaste 11 während der Dauer des Druckes Naßdampf zu versprühen und dadurch die Reinigungswirkung in der gewünschten Weise zu erhöhen.If there is an increased need for cleaning, the User briefly by pressing the pushbutton 11 open the liquid supply line 9 and this leads that the high pressure of the steam in the steam room 4 hot water from the water room 2 through the Riser pipe 8 pressed into the liquid supply line 9 becomes. In this short-term liquid flow occurs the steam from the steam line 6 and thereby forms a homogeneous wet steam mixture, which then over the Closing valve 7 is supplied to the steam delivery element. It is possible by pressing pushbutton 11 to spray wet steam during the duration of the pressure and thereby the cleaning effect in the desired Way to increase.
