Beschreibung description
[0001] Die Erfindung betrifft einen Wäschetrockner oder Waschautomaten gemäss Oberbegriff von Anspruch 1. The invention relates to a tumble dryer or washing machine according to the preamble of claim 1.
[0002] Derartige Geräte werden verwendet, um Wäsche zu waschen oder zu trocknen. Sie sind ausgestaltet mit Mitteln, um der Wäsche Wasser zu entziehen. In Waschautomaten handelt es sich dabei in der Regel um ein Schleuderprogramm, bei welchem die Wäsche zentrifugiert wird. In Wäschetrocknern wird der Wäsche zum Entwässern normalerweise Trockenluft zugeführt. Such devices are used to wash or dry laundry. They are designed with means to remove water from the laundry. In washing machines it is usually a spin program in which the laundry is centrifuged. In tumble dryers, the laundry is normally supplied with dry air for dewatering.
[0003] In beiden Fällen ist es wichtig, dass die Wäsche möglichst wenig zerknittert wird. Es stellt sich deshalb die Aufgabe, einen Wäschetrockner oder Waschautomaten bereitzustellen, bei dem die Wäsche bei der Entnahme möglichst wenig zerknittert ist. In both cases, it is important that the laundry is crumpled as little as possible. It is therefore the object to provide a tumble dryer or washing machine, in which the laundry is as little as possible wrinkled during removal.
[0004] Diese Aufgabe wird vom Wäschetrockner bzw. vom Waschautomaten gemäss Anspruch 1 erfüllt. This object is met by the tumble dryer or the washing machine according to claim 1.
[0005] Erfindungsgemäss ist der Wäschetrockner bzw. Waschautomat also so ausgestaltet, dass nach dem Entzug von Wasser die Wäsche mit Dampf beaufschlagt wird. Es zeigt sich, dass hierdurch Knitter reduziert werden können, und zwar schon mit Dampfmengen, die im Vergleich zu der der Wäsche entzogenen Wassermenge gering sind. According to the invention, the tumble dryer or washing machine is thus designed so that after the withdrawal of water, the laundry is subjected to steam. It turns out that this can reduce wrinkles, and indeed already with amounts of steam that are small compared to the amount of water extracted from the laundry.
[0006] Mit dem Dampf können die Wäsche und das Gerät gleichzeitig auch entkeimt werden. Vorzugsweise soll dabei die Temperatur der zu entkeimenden Teile mindestens 60°C erreichen. Hierzu ist, je nach Aufbau des Geräts, typischerweise eine Wassertemperatur von mindestens 70°C, in der Regel mindestens 80°C, notwendig. With the steam, the laundry and the device can be sterilized at the same time. Preferably, the temperature of the parts to be sterilized should reach at least 60 ° C. For this purpose, depending on the design of the device, typically a water temperature of at least 70 ° C, usually at least 80 ° C, necessary.
[0007] Besonders zweckmässig wird die Erfindung bei Geräten eingesetzt, bei denen der Wäsche durch Zentrifugieren («Schleudern») Wasser entzogen wird. Dabei entstehen Falten, die durch den Dampf wieder entfernt werden können. Particularly expediently, the invention is used in devices in which the laundry by centrifugation ("spin") water is withdrawn. This creates wrinkles that can be removed by the steam again.
[0008] Weitere bevorzugte Ausführungen sowie Vorteile der Erfindung ergeben sich aus den abhängigen Ansprüchen sowie der nun folgenden Beschreibung anhand der Figur. Dabei zeigt: Further preferred embodiments and advantages of the invention will become apparent from the dependent claims and the following description with reference to the figure. Showing:
[0009] Fig. 1 einen Schnitt durch einen stark vereinfacht dargestellten Waschautomaten. Fig. 1 shows a section through a washing machine shown greatly simplified.
[0010] Der in Fig. 1 dargestellte Waschautomat besitzt ein Gehäuse 1, in welchem eine Trommel 2 mit ungefähr horizontaler Drehachse angeordnet ist. Die Trommel 2 bildet das Gefäss zum Aufnehmen der zu waschenden Wäsche. Sie ist wasserdurchlässig und in einem wasserdichten Bottich 3 angeordnet. Zum Zuführen und Abführen von Wasser sind Leitungen 5, 6 vorgesehen, welche mit einem elektrisch gesteuerten Ventil 7 und einer Ablaufpumpe 8 versehen sind. Ein Motor 9 dient zum Drehen der Trommel. The washing machine shown in Fig. 1 has a housing 1 in which a drum 2 is arranged with approximately horizontal axis of rotation. The drum 2 forms the vessel for receiving the laundry to be washed. It is permeable to water and arranged in a watertight tub 3. For supplying and discharging water lines 5, 6 are provided, which are provided with an electrically controlled valve 7 and a drain pump 8. A motor 9 is used to rotate the drum.
[0011] Zum Steuern des Waschautomaten ist eine Steuerung 10 vorgesehen. Diese ist in der Lage, die oben erwähnten Komponenten aufgrund von Vorgaben des Benutzers: in konventioneller Weise und durch Auswertung von Senso-rik-Signalen zu steuern. For controlling the washing machine, a controller 10 is provided. This is able to control the above-mentioned components on the basis of user specifications: in a conventional manner and by evaluation of sensory signals.
[0012] Bei einem typischen Waschvorgang wird Wäsche in die Trommel 2 eingebracht. Diese wird unter Zugabe von Wasser und Waschmitteln und unter Drehen der Trommel 2 gewaschen. Dabei wird so viel Wasser 11 in den Bottich 3 eingefüllt, dass sich zumindest der untere Teil der Trommel im Wasser befindet und die Wäsche benetzt wird. Zum Aufheizen des Wassers auf eine gewünschte Waschtemperatur ist am Boden des Bottichs 3 eine Heizung 12 vorgesehen. In a typical washing process, laundry is introduced into the drum 2. This is washed with the addition of water and detergents and with rotation of the drum 2. In this case, so much water 11 is filled into the tub 3, that at least the lower part of the drum is in the water and the laundry is wetted. For heating the water to a desired washing temperature, a heater 12 is provided at the bottom of the tub 3.
[0013] Nach dem Waschen wird, soweit der Benutzer dies verlangt hat, die Wäsche geschwungen, d.h. es wird der Wäsche durch schnelles Drehen der Trommel 2 Wasser entzogen. After washing, as far as the user has requested, the laundry is swung, i. it is the laundry by quickly turning the drum 2 withdrawn water.
[0014] Nach dem Schleudern wird die Trommel 2 langsam abwechslungsweise in beide Richtungen gedreht («reversiert»). Da die Trommel eine im Wesentlichen horizontale Drehachse besitzt, wird dabei die Wäsche aufgelockert. After spinning, the drum 2 is slowly alternately rotated in both directions ("reversed"). Since the drum has a substantially horizontal axis of rotation, while the laundry is loosened.
[0015] Nach dem Schleudern der Wäsche wird in den Bottich 2 wieder Wasser eingelassen, und zwar so, dass die Wäsche dabei nicht benetzt wird. In dem in Fig. 1 dargestellten Ausführungsbeispiel ist hierzu eine separate zweite Zufuhrleitung 13 mit Steuerventil 14 vorgesehen, die in einen unteren Bereich des Bottichs 3 mündet. Es wird so viel Wasser eingelassen, dass die Heizung 12 bedeckt ist, der Wasserpegel 14 jedoch noch unterhalb der Trommel 2 liegt. After spinning the laundry water is recirculated into the tub 2, in such a way that the laundry is not wetted. In the exemplary embodiment illustrated in FIG. 1, a separate second supply line 13 with control valve 14 is provided for this purpose, which opens into a lower region of the tub 3. It is so much water admitted that the heater 12 is covered, the water level 14 but still below the drum 2.
[0016] Sodann wird das Wasser mit der Heizung 12 aufgeheizt, und zwar mindestens auf 40°C, vorzugsweise auf mindestens 70°C, so dass es zu einer Dampfentwicklung im Bottich 3 kommt. Der Dampf dringt in die Trommel 2 ein und beaufschlagt die Wäsche. Then, the water is heated with the heater 12, at least to 40 ° C, preferably to at least 70 ° C, so that it comes to a vapor development in the tub 3. The steam penetrates into the drum 2 and acts on the laundry.
[0017] Während der Bedampfung der Wäsche wird die Trommel vorzugsweise weiter reversiert, so dass die Wäsche möglichst gleichmässig bedampft wird. Dabei glätten sich Knitter. Gleichzeitig werden die Wäsche, die Trommel 2 und der Bottich 3 entkeimt, was insbesondere dann wichtig ist, wenn die Wäsche nur mit 40°C oder weniger gewaschen wurde. Dabei wird weniger Wasser und Energie benötigt als bei konventionellen Entkeimungsprogrammen. During the vapor deposition of the laundry, the drum is preferably reversed further, so that the laundry is steamed as evenly as possible. It smoothen wrinkles. At the same time, the laundry, the drum 2 and the tub 3 are sterilized, which is particularly important if the laundry has been washed only at 40 ° C or less. This requires less water and energy than conventional disinfection programs.
[0018] Wenn eine effiziente Entkeimung gewünscht wird, sollten die zu entkeimenden Teile mindestens eine Temperatur von 60°C erreichen. Hierzu muss das Wasser am Boden des Bottichs 3 je nach Konstruktion und Grösse des Geräts in der Regel auf mindestens ca. 70°C, oftmals sogar auf mindestens 80°C, aufgeheizt werden. If an efficient degerming is desired, the parts to be sterilized should reach at least a temperature of 60 ° C. For this purpose, the water at the bottom of the tub 3, depending on the construction and size of the device usually to at least about 70 ° C, often even at least 80 ° C, heated.
[0019] Die Bedampfung dauert vorzugsweise zwischen 5 und 20 Minuten. Danach wird die Heizung 12 abgeschaltet und das Wasser wird abgepumpt. Nach einer Abkühlphase (während der die Wäsche weiter reversiert werden kann) ist der Vorgang beendet und die Tür des Waschautomaten kann freigegeben werden. The evaporation preferably lasts between 5 and 20 minutes. Thereafter, the heater 12 is turned off and the water is pumped out. After a cooling phase (during which the laundry can be reversed further), the process is completed and the door of the washing machine can be released.
[0020] All diese Abläufe werden von der Steuerung 10 kontrolliert und überwacht. All of these operations are controlled and monitored by the controller 10.
[0021] Es zeigt sich, dass mit der hier beschriebenen Vorrichtung Knitter reduziert werden können, insbesondere in It turns out that wrinkles can be reduced with the device described here, in particular in
2 2
CH 695 383 A5 CH 695 383 A5
Mischgeweben und synthetischen Geweben sowie bei besonders feinfadigen Geweben, z.B. Kaschmir. Dennoch wird der Wassergehalt der Wäsche durch die Bedampfung nicht übermässig erhöht, insbesondere wenn die Wäsche mit Schleuderzahlen von höchstens 1000 min-1 geschleudert wurde. Blended fabrics and synthetic fabrics, as well as particularly fine weave fabrics, e.g. Cashmere. Nevertheless, the water content of the laundry is not excessively increased by the steaming, especially if the laundry was spun with a spin rate of at most 1000 min-1.
[0022] Die zum Bedampfen benötigte Wassermenge ist gering. Um den Wasserverbrauch zu minimieren, kann auch Spülwasser aus dem letzten Spülgang in einem geeigneten Ausweichgefäss zurückbehalten und zum Bedampfen wieder in den Bottich 3 gepumpt werden. In diesem Fall kann die Zufuhrleitung 13 für Frischwasser entfallen. The amount of water required for steaming is low. To minimize water consumption, rinse water from the last rinse cycle can be retained in a suitable alternative vessel and pumped back into the tub 3 for vapor deposition. In this case, the supply line 13 for fresh water can be omitted.
[0023] Im dargestellten Beispiel wird die Heizung 12, welche auch beim Waschen zum Heizen des Wassers verwendet wird, als Bedampfungseinrichtung eingesetzt. Es ist jedoch auch denkbar, eine separate Bedampfungseinrichtung bereitzustellen, die z.B. ausserhalb des Bottichs 3 angeordnet werden kann. In the example shown, the heater 12, which is also used for washing to heat the water, used as a vapor deposition. However, it is also conceivable to provide a separate sputtering device, e.g. outside the tub 3 can be arranged.
[0024] Nebst dem Glätten von Knittern kann mit der hier beschriebenen Bedampfung, wie bereits erwähnt, auch eine Entkeimung durchgeführt werden. Es kann deshalb sinnvoll sein, die Bedampfung im Rahmen eines Hygieneprogramms auch nur zur Entkeimung an der leeren Trommel durchzuführen. In addition to the smoothing of wrinkles can be performed with the steaming described here, as already mentioned, a sterilization. It may therefore be useful to perform the steaming in the context of a hygiene program only for sterilization of the empty drum.
[0025] Obwohl Waschautomaten das bevorzugte Anwendungsgebiet der Erfindung sind, kann die Erfindung auch bei Wäschetrocknern eingesetzt werden. Diese Geräte besitzen normalerweise ebenfalls eine Trommel, die als Gefäss für die Wäsche dient und in welche Trockenluft zum Trocknen der Wäsche eingeführt wird. Auch hier kann nach dem Trocknen die Wäsche bedampft werden, wobei ein separater Dampferzeuger vorzusehen ist. Dieser erzeugt Dampf, der in die Trommel eingeblasen wird. Dabei wird die Wäsche vorzugsweise wiederum bewegt, um eine gleichmässige Bedampfung sicherzustellen. Vorzugsweise wird der Dampf von unten in die Trommel eingeblasen, so dass er durch die Wäsche hindurchtreten muss. Although automatic washing machines are the preferred field of application of the invention, the invention can also be used in tumble dryers. These devices usually also have a drum which serves as a vessel for the laundry and into which dry air is introduced for drying the laundry. Again, the laundry can be steamed after drying, with a separate steam generator is provided. This generates steam, which is blown into the drum. In this case, the laundry is preferably in turn moved to ensure uniform evaporation. Preferably, the steam is blown from below into the drum so that it must pass through the laundry.
[0026] Auch bei Wäschetrocknern können mit der Erfindung Knitter reduziert werden, insbesondere bei feinfadigen Geweben, z.B. Kaschmir, und es kommt zu einer Entkeimung. Gleichzeitig wird die Trocknung vergleichmässigt, d.h. der Trocknungsgrad ist über die ganze Wäsche ungefähr homogen. Even with tumble driers can be reduced with the invention wrinkles, especially in feinfadigen tissues, e.g. Cashmere, and it comes to a sterilization. At the same time the drying is made uniform, i. the degree of drying is approximately homogeneous throughout the wash.
