Abstract

A combined washing and tumble-drying machine uses a drying cycle in which the drum revolves at a speed of approx. 50 rpm for 3-10 min., and is then switched to a speed of 200-450 rpm for 5-30 sec., this cycle being repeated throughout the drying phase. The short-period, high-speed rotation may also be performed at least once during the cooling phase, in which the heater is switched off. This procedure increases the evaporation rate of the moisture in the load, giving shorter drying times with increased efficiency of power utilisation.

Description

Verfahren zur Durchführung des Trocknungs- Procedure for carrying out the drying

programms in einer Trommelwasch- und Trockenmaschine Die Erfindung bezieht sich auf ein Verfahren zur Durchführung des Trocknungsprogramms in einer Trommelwasch-und Trockenmaschine. programs in a drum washing and drying machine The invention refers to a method of running the drying program in one Drum washing and drying machine.

Es sind kombinierte Wasch- und Trockenmaschinen bekannt, bei denen die Prozesswärme durch eine nach dem Strahlungsprinzip wirkende Heizvorrichtung zugeführt wird und die eine Kondensationseinrichtung für den aus der Wäsche ausgetriebenen Dampf aufweisen. (DE-OS 20 47 856) Waschtrockner der heute gebräuchlichen Art besitzen den Vorteil, daß sie in einem einzigen Gerät das Waschen, Schleudern sowie Trocknen der Wäsche ermöglichen und dadurch bei beengten Platzverhältnissen gegenüber zwei Einzelgeräten bevorzugt werden.There are combined washing and drying machines known in which the process heat through a heating device that works according to the radiation principle is supplied and a condensation device for the expelled from the laundry Have steam. (DE-OS 20 47 856) own washer-dryer of the type commonly used today the advantage that you can wash, spin and dry in a single device enable the laundry and thus in confined spaces compared to two Individual devices are preferred.

Auf der anderen Seite besitzen sie aber eine Reihe erheblicher Nachteile, die vornehmlich durch den Trocknungsvorgang hervorgerufen werden. Der Trocknungsprozess läßt sich meist nur mit einem schlechten Wirkungsgrad durchführen, was sich durch übermäßig lange Trocknungszeiten bemerkbar macht.On the other hand, they have a number of significant disadvantages, which are primarily caused by the drying process. The drying process can usually only be carried out with a poor degree of efficiency, which can be achieved through makes excessively long drying times noticeable.

Der Erfindung liegt daher die Aufgabe zugrunde, bei den kombinierten Trommelwasch- und Trockenmaschinen der eingangs genannten Art den Trocknungsvorgang zu beschleunigen und ihn mit einem verbesserten Wirkungsgrad ablaufen zu lassen.The invention is therefore based on the object in the combined Drum washing and drying machines of the type mentioned above, the drying process to accelerate and run it with an improved efficiency.

Die Lösung dieser Aufgabe wird durch das im Hauptanspruch gekennzeichnete Verfahren erzielt.The solution to this problem is characterized by what is defined in the main claim Procedure achieved.

Weitere Merkmale und Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen und der Beschreibung.Further features and configurations of the invention emerge from the following subclaims and the description.

Die mit der erfindungsgemäßen Maßnahme betriebenen Waschtrockner haben überraschend, deutliche Verbesserungen im Trocknungsablauf erkennen lassen. Die Trocknungszeit wurde gegenüber der früheren Arbeitsweise merklich verkürzt. Ein weiterer Vorteil kann auch noch darin gesehen werden, daß höhere Heizleistungen zur Anwendung kommen, wodurch sich die Verdampfungsgeschwindigkeit der in der Wäsche gebundenen Feuchtigkeit erhöht.The washer-dryers operated with the measure according to the invention have surprisingly, clear improvements in the drying process can be seen. the The drying time has been noticeably shortened compared to the previous way of working. A Another advantage can also be seen in the fact that higher heating outputs come into use, thereby reducing the rate of evaporation in the laundry bound moisture increases.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachstehend näher erläutert.An embodiment of the invention is shown in the drawings shown schematically and will be explained in more detail below.

Es zeigen: Fig. 1 eine Trommelwasch- und Trockenmaschine von der Seite gesehen im Schnitt, Fig. 2 ein Drehzahl-Zeitdiagramm für den Trocknungsvorgang.1 shows a drum washing and drying machine from the side seen in section, FIG. 2 shows a speed-time diagram for the drying process.

In der Fig. 1 ist eine Waschtrockner-Kombination dargestellt, bei der das erfindungsgemäße Verfahren anwendbar ist.In Fig. 1, a washer-dryer combination is shown in to which the method according to the invention is applicable.

Im Laugenbehälter 1 des Waschtrockners 2 ist die Wäschetrommel 3 drehbar gelagert. Die Wäschetrommel 3 wird von einem Antriebsmotor 4 über einen Riementrieb 5 angetrieben, wobei mehrere Drehzahlen einstellbar sind.In the tub 1 of the washer dryer 2, the laundry drum 3 is rotatable stored. The laundry drum 3 is driven by a drive motor 4 via a belt drive 5 driven, whereby several speeds can be set.

Im unteren-Bereich des Laugenbehälters ist eine Heizvorrichtung 6,die sowohl der Erwärmung der Waschlauge im Waschgang als auch der Beheizung im Trocknungsgang dient.In the lower area of the tub is a heating device 6, which both the heating of the detergent solution in the wash cycle and the heating in the drying cycle serves.

Durch Bestrahlung der sich drehenden Wäschetrommel 3 wird die für das Trocknen erforderliche Prozesswärme zugeführt.By irradiating the rotating laundry drum 3, the for the required process heat is supplied to the drying process.

Der aus der Wäsche ausgetriebene Wasserdampf wird zur Kondensation in eine Kondensationseinrichtung 7 geleitet.The water vapor expelled from the laundry becomes condensation passed into a condensation device 7.

Die Fig. 2 zeigt ein Drehzahl-Zeitdiagramm eines erfindungsgemäßen Verfahrens. Hierbei wird im Trocknungsprogramm bei eingeschalteter Heizung 6 die Wäschetrommel 3 zunächst mit der normalen Trocknungsdrehzahl n1 bewegt, die in der Regel bei ca. 50 U/min liegt. Nach Ablauf der Zeit t1 wird die Drehzahl der Wäschetrommel 3 für die Zeitdauer t2 kurzzeitig auf eine Zwischenschleuderdrehzahl n2 beschleunigt und anschließend wieder auf die normale Trocknungsdrehzahl n1 zurückgeführt. Dieser Vorgang kann sich im reinen Trocknungsbetrieb mehrmals wiederholen und kann auch in der nachfolgenden Abkühlphase bei abgeschalteter Heizung mindestens einmal vorgesehen sein.Fig. 2 shows a speed-time diagram of an inventive Procedure. Here, in the drying program with the heater 6 switched on, the Laundry drum 3 initially moved at the normal drying speed n1, which is in the Usually around 50 rpm. After the time t1 has elapsed, the speed of the laundry drum becomes 3 accelerated briefly to an intermediate spin speed n2 for the period t2 and then returned to the normal drying speed n1. This The process can and can be repeated several times in pure drying mode provided at least once in the subsequent cooling phase with the heating switched off be.

Die bei dem vorbeschriebenen Verfahren zur Anwendung kommenden Drehzahlbereiche n1 - n2 sowie die Zeitbereiche t1 und t2 können je nach den Verhältnissen des Waschtrockners unterschiedlich sein.The speed ranges used in the method described above n1 - n2 and the time ranges t1 and t2 can vary depending on the conditions of the washer-dryer be different.

Bei einem Waschtrockner mit der 551-Trommel haben sich z. B.In a washer-dryer with the 551 drum z. B.

folgende Drehzahl- und Zeitbereiche als günstig erwiesen: n1 = 50 U/min, t1 = 3 - 10 min n2 = 200 - 450 U/min, t2 = 5 - 30 sec Mit dem erfindungsgemäßen Verfahren kann auf ein zusätzliches Gebläse zur Luftumwälzung verzichtet werden und trotzdem mit höheren Heizleistungen gearbeitet werden.the following speed and time ranges have proven to be favorable: n1 = 50 Rpm, t1 = 3 - 10 min, n2 = 200 - 450 rpm, t2 = 5 - 30 sec With the method according to the invention can rely on an additional fan for air circulation can be dispensed with and still work with higher heating outputs.

Es stellt sich in dem System automatisch eine gleichmäßige Luft- und Temperaturverteilung ein, wodurch der Trocknungsprozess erheblich begünstigt wird.An even air and air flow is automatically created in the system Temperature distribution, which significantly promotes the drying process.
