Description

Die Erfindung betrifft ein Verfahren zur Behandlung von Textilien in einer Haushaltsmaschine, insbesondere einem Haushaltswäschetrockner, und eine Haushaltsmaschine, beispielsweise einen Haushaltswäschetrockner, nach dem Oberbegriff der Patentansprüche 1 und 8.The invention relates to a method for treating textiles in a household machine, in particular a household clothes dryer, and a household machine, for example a household clothes dryer, according to the generic term of Claims 1 and 8.

Aus der DE 34 08 136 A1 ist ein Wäschetrockner bekannt, bei dem mittels einer externen Gaszuführleitung ein aus Nebel und Dampf bestehendes Gemisch in einen Wäschebehandlungsraum geleitet wird. Der bekannte Wäschetrockner erfordert das Vorsehen einer externen Nebel- und Dampferzeugungsvorrichtung. Das in den Wäschebehandlungsraum eingeleitete Gemisch aus Nebel und Dampf ist relativ kalt. Es ist nicht besonders reinigungsaktiv. Schließlich bilden sich Tropfen, welche zur Bildung von Flecken auf den Textilien führen können.A tumble dryer is known from DE 34 08 136 A1, at which by means of an external gas supply line from fog and Steam existing mixture passed into a laundry treatment room becomes. The known tumble dryer requires provision an external mist and steam generating device. The mixture of mist introduced into the laundry treatment room and steam is relatively cold. It is not particularly active in cleaning. Eventually, drops form which form the formation of stains on the textiles.

Aus der DE 37 27 570 ist ein Verfahren zur Beseitigung von Gerüchen aus Textilien bekannt. Dabei werden in einem Schrank aufgenommene Textilien mit Trockendampf und geruchsbindenden Mitteln beaufschlagt. Eine Vorrichtung zur Erzeugung des Trockendampfs ist hier ebenfalls außerhalb des Schranks vorgesehen.DE 37 27 570 describes a method for eliminating Smells known from textiles. Doing so in a closet absorbed textiles with dry steam and odor-binding Funds applied. A device for generating the dry steam is also provided outside the cabinet here.

Das Vorsehen externer Dampferzeugungsvorrichtungen ist umständlich und aufwändig. Eine solche Maßnahme kommt für Haushaltseinrichtungen wie Haushaltsmaschinen nicht in Betracht. The provision of external steam generating devices is cumbersome and complex. Such a measure comes for household facilities like household machines out of the question.

Die bekannten Haushaltsmaschinen, insbesondere Wäschetrockner, bewahren nach der Beendigung des Trockenprogrammes die getrocknete Wäsche so lange in ihrem Inneren auf, bis sie für die Weiterverarbeitung, beispielsweise dem Bügeln, von einer Bedienperson entnommen wird. Insbesondere durch nicht sofortiges Weiterverarbeiten der entnommenen Wäsche kann diese weitere Feuchtigkeit verlieren, so dass sie für eine Weiterverarbeitung, insbesondere für das Bügeln, zu wenig Feuchtigkeit enthält. Um diesen zu starken Flüssigkeitsverlust wieder auszugleichen, ist es bekannt, vor dem Bügeln die Wäsche mit fein zerstäubtem Wasser wieder einzusprühen, um das Bügeln der Wäsche effektiver und einfacher zu gestalten. Bei diesem Besprühen kann allerdings nicht zuverlässig erreicht werden, dass eine gleichmäßige Befeuchtung der zu bügelnden Wäschestücke erzielt wird.The known household machines, especially tumble dryers, keep the after the drying program dried laundry inside until it is for further processing, for example ironing, of one Operator is removed. Especially not by immediate The laundry can be further processed lose more moisture so they can be used for further processing, especially for ironing, too little moisture contains. To make this too much fluid loss again to compensate, it is known to use the laundry before ironing spray finely atomized water again to iron make laundry more effective and easier. With this However, spraying cannot be reliably achieved that even moistening of the laundry items to be ironed is achieved.

Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es sollen insbesondere ein Verfahren sowie eine Haushaltsmaschine, beispielsweise ein Haushaltswäschetrockner, angegeben werden, mit denen eine einfache und effektive Entfernung unerwünschter Textilgerüche erreichbar ist sowie eine gleichmäßige Befeuchtung der Wäsche, ohne dabei das Waschergebnis durch beispielsweise Fleckenbildung zu verschlechtern.The object of the invention is to overcome the disadvantages of the prior art of technology to eliminate. In particular, it should be a procedure and a household machine, for example a household clothes dryer, be specified with which a simple and effective removal of unwanted textile odors as well as an even moistening of the laundry, without the washing result due to, for example, staining to deteriorate.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 23 gelöst. Zweckmäßige Ausgestaltungen ergeben sich aus den Merkmalen der übrigen Ansprüche.This object is achieved by the features of claims 1 and 23 solved. Appropriate configurations result from the Features of the remaining claims.

Durch das Verfahren gemäß der Erfindung wird erreicht, dass in der Haushaltsmaschine ein Heißdampf zur Verfügung gestellt werden kann, der unmittelbar nach der Erzeugung direkt der Wäsche zugeführt werden kann. Dies wird vorteilhaft dadurch ermöglicht, dass die Erzeugung direkt in der Haushaltsmaschine erfolgt, wodurch extrem kurze Transportwege für den Wasserdampf zur Verfügung stehen, so dass keine Kondensatbildungen, und damit Tropfenbildungen, stattfinden können. Wärmeverlustes des Dampfes werden durch die kurzen Leitungslängen auf ein Minimum reduziert, so dass der Dampf auch gesteuert mit einer gewünschten Temperatur der Wäsche zugeführt werden kann. Die Temperatur des Dampfes ändert sich auf dem Weg vom Dampferzeuger zur Wäsche praktisch nicht, da die Transportwege extrem kurz sind. Es entfällt damit das aufwendige Vorsehen einer externen Dampferzeugungsvorrichtung. Es kommt nicht zur unerwünschten Kondensation und damit zur Tropfenbildung in der Heißdampfleitung.It is achieved by the method according to the invention that a superheated steam is made available in the household machine can be the immediately after the generation of the Laundry can be fed. This will be beneficial enables generation directly in the household machine takes place, making extremely short transport routes for the water vapor are available so that no condensate formation, and thus drop formation can take place. heat loss of steam are due to the short line lengths reduced to a minimum so that the steam is also controlled can be fed to the laundry at a desired temperature can. The temperature of the steam changes on the way from Steam generator for laundry practically not, since the transport routes are extremely short. This eliminates the complex provision an external steam generating device. It doesn't come for undesirable condensation and thus for droplet formation in the superheated steam line.

Besonders vorteilhaft werden die Textilien intervällweise mit tropfenfreiem Heißdampf beaufschlagt. Die Beaufschlagung mit tropfenfreiem Heißdampf ist besonders effektiv. Es wird schnell eine Entfernung von Gerüchen aus Textilien erreicht. Die Bildung von Flecken wird vermieden. Die intervallweise Beaufschlagung mit Heißdampf bewirkt eine besonders intensive Auffrischung und Entkeimung geruchsbelasteter Textilien.The textiles are particularly advantageous at intervals drop-free superheated steam. The application of non-drip hot steam is particularly effective. It will quickly removes odors from textiles. The formation of stains is avoided. The intermittent Exposure to superheated steam causes a particularly intense Refreshing and disinfecting odor-laden textiles.

Nach einem weiteren Ausgestaltungsmerkmal sind der Dampferzeuger und eine Wasserzuführvorrichtung derart geregelt, dass dem Dampferzeuger erst bei Erreichen einer Arbeitstemperatur von zumindest 100°C, vorzugsweise 120 - 200°C, eine vorgegebene Menge an Wasser zugeführt wird. Mit dieser Maßnahme wird weiter sichergestellt, dass der erzeugte Heißdampf tropfenfrei ist. Das Wasser gelangt erst dann in den Dampferzeuger, wenn dieser auf eine ausreichende für eine vollständige Dampferzeugung notwendige Arbeitstemperatur aufgeheizt ist. Zweckmäßigerweise wird die Menge des zugeführten Wassers in Abhängigkeit der Arbeitstemperatur oder der aufgenommenen elektrischen Leistung des Dampferzeugers so geregelt, dass das Wasser vollständig verdampft wird. Es wird mittels der Regelung die Zufuhr einer zu großen Wassermenge vermieden. Eine Bildung von Wassertropfen im Heißdampf wird damit unterbunden.According to a further design feature, the steam generator and a water supply device controlled such that the steam generator only when a working temperature is reached a predetermined of at least 100 ° C, preferably 120-200 ° C Amount of water is supplied. With this measure further ensures that the hot steam generated is drop-free is. The water only gets into the steam generator if this is sufficient for a complete Steam generation necessary working temperature is heated. Appropriately, the amount of water supplied in Dependency of the working temperature or the absorbed electrical Power of the steam generator regulated so that the Water is completely evaporated. It is by means of the scheme the supply of too much water avoided. A This prevents the formation of water drops in superheated steam.

Eine Wasserzuführung zum Dampferzeuger kann durch intervallweises Öffnen eines Ventils und/oder Betätigen einer Pumpe erfolgen. Im Falle des alleinigen Vorsehens eines Ventils ist ein Versorgungstänk der Wasserzuführvorrichtung oberhalb des Dampferzeugers angeordnet.A water supply to the steam generator can be done at intervals Opening a valve and / or operating a pump respectively. In the case of the sole provision of a valve a supply tank of the water supply device above the Steam generator arranged.

Nach einer weiteren besonders vorteilhaften Ausgestaltung wird der im Dampferzeuger erzeugte Heißdampf über eine, vorzugsweise thermisch isolierte, Steigleitung in einen von der Wäschetrommel umgebenen Behandlungsraum geleitet. Das Vorsehen einer Isolierung wirkt einer unerwünschten Abkühlung des Heißdampfs und damit einer Kondensation bzw. einer Bildung von Tropfen entgegen. Ein eventuell an der Wand der Leitung gebildetes Kondensat fließt wegen der Steigung der Leitung in Richtung des Dampferzeugers zurück. Es wird ein Einblasen von mit Tropfen belastetem Heißdampf in den Behandlungsraum vermieden.According to a further particularly advantageous embodiment the superheated steam generated in the steam generator via a, preferably thermally insulated, riser into one of the Headed to the laundry drum surrounding the treatment room. The provision insulation acts to cool down the Superheated steam and thus condensation or formation of drops. One possibly on the wall of the line formed condensate flows in due to the slope of the line Back towards the steam generator. It will blow in Avoid droplets of hot steam in the treatment room.

Nach einer weiteren vorteilhaften Ausgestaltung wird dem Wasser oder dem Heißdampf Duftstoff, Entkeimungsmittel, Reinigungsmittel und/oder Entkalkungsmittel zugesetzt. Damit wird eine besonders effektive Reinigung geruchsbelasteter Textilien erreicht. Sofern bereits dem Wasser die vorgenannten Zusätze zugesetzt werden, ist darauf zu achten, dass diese rückstandsfrei verdampfen. Zusätze welche nicht rückstandsfrei verdampfen, werden zweckmäßigerweise dem Heißdampf beigemischt.According to a further advantageous embodiment, the water or the hot steam fragrance, disinfectant, cleaning agent and / or descaling agent added. So that will a particularly effective cleaning of odor-contaminated textiles reached. If the water already contains the aforementioned additives care must be taken that this Evaporate without residue. Additives which are not residue-free evaporate, are advantageously mixed with the superheated steam.

Durch das vorteilhafte Verfahren, bei dem der Dampferzeuger gesteuert mit Wasser versorgt wird, wird vorteilhaft erreicht, dass immer nur so viel Wasser zugeführt wird, wie der Dampferzeuger auch zu Dampf umsetzen kann. Vorteilhaft wird dabei das Wasser einem Tank entnommen, der in der Haushaltsmaschine integriert ist. Vorteilhaft kann dies ein Tank sein, in dem beispielsweise das Kondensat, das bei einem Trockenvorgang eines Haushaltswäschetrockners entsteht, gesammelt wird.By the advantageous method in which the steam generator controlled water supply is advantageously achieved that only as much water is added as the Steam generator can also convert to steam. Will be beneficial thereby taking the water from a tank in the household machine is integrated. This can advantageously be a tank in which, for example, the condensate that occurs during a drying process of a household dryer is collected becomes.

In vorteilhafter Weiterbildung der Erfindung wird die Wäsche mit einer vorgegebenen Menge an Heißdampf beaufschlagt, dadurch ist es möglich, dass über das erfindungsgemäße Verfahren die Wäsche mit einem vorgegebenen gewünschten Feuchtigkeitsgrad befeuchtet werden kann. Dazu kann günstigerweise die Betriebszeit des Dampferzeugers bestimmt werden, so dass eine vorgegebene Feuchtigkeitsmenge zur Wäsche gelangt. In anderer vorteilhafter Weiterbildung der Erfindung wird die Wäsche mit Heißdampf so lange beaufschlagt, bis sie einen vorgegebenen Feuchtegrad besitzt. Dazu wird das erfindungsgemäße Verfahren dahingehend weitergebildet, dass der Feuchtegrad der Wäsche durch eine Sensoreinrichtung überwacht wird. In besonders günstiger Ausgestaltung der Erfindung ist die Sensoreinrichtung eine Sensoreinrichtung, die in einer Haushaltsmaschine, beispielsweise einem Haushaltswäschetrockner, vorhanden ist, um die Überwachung der Restfeuchte beim Trockenvorgang durchzuführen. Erfindungsgemäß verwendet somit das Verfahren eine solche Sensoreinheit.In an advantageous development of the invention, the laundry supplied with a predetermined amount of superheated steam, thereby it is possible that using the method according to the invention the laundry with a predetermined desired level of moisture can be moistened. This can be done conveniently the operating time of the steam generator can be determined so that a predetermined amount of moisture reaches the laundry. In Another advantageous development of the invention is the Steam is subjected to superheated steam until it reaches you has a predetermined degree of moisture. For this purpose, the invention Process further developed in that the degree of moisture the laundry is monitored by a sensor device becomes. In a particularly favorable embodiment of the invention the sensor device is a sensor device which in a Household machine, for example a household clothes dryer, is present to monitor the residual moisture when Carry out drying process. Thus used according to the invention the method of such a sensor unit.

In einer anderen Ausgestaltung der Erfindung wird die Wäsche mit zeitlichen Unterbrechungen mit Heißdampf beaufschlagt, so dass die Wäsche zur Gänze auch in ihrem Inneren einen vorgegebenen Feuchtegrad besitzt.
