Abstract

To avoid movable or separable supply lines, the inner drum (7) arranged horizontally within an outer drum (15) connected to the housing (1) is tilted for the purpose of emptying toward the discharge opening (10) while the housing (1) plus ventilator (2) and heating means (4) remains stationary even during the emptying of the drum. <IMAGE>

Description

Die Erfindung betrifft einen Wäschetrockner mit einer kippbaren Trommel.The invention relates to a tumble dryer with a tiltable drum.

In Wäschereibetrieben werden Trommeltrockner zum Trocknen der gewaschenen Wäscheposten eingesetzt, bei denen warme Luft durch die um eine waagrechte Achse rotierende Trommel geleitet wird. Die Belüftung der Trommel geschieht dabei vermittels Ventilatoren, welche Luft aus dem Trommelgehäuse absaugen und gleichzeitig über ein Heizregister Frisch- oder auch Umluft ansaugen. An der einen Stirnseite der Trommel befindet sich im Gehäuse des Wäschetrockners die Beschickungsöffnung und an der gegenüberliegenden Stirnseite die Entleerungsöffnung. Um den Wäschetrockner bequem und automatisch entleeren zu können, ist es üblich den gesamten Trockner an der der Entleerungsöffnung gegenüberliegenden Seite während des Entleerungsvorganges anzuheben. Durch die so erreichte Schräglage: der Trommel wird die Wäsche aus der sich drehenden Trommel durch die geöffnete Entleerungsöffnung in einen bereitstehenden Behälter gefördert.Drum dryers are used in laundries to dry the washed laundry items, in which warm air is conducted through the drum rotating about a horizontal axis. The drum is ventilated by means of fans, which extract air from the drum housing and at the same time suck in fresh or recirculated air via a heating register. The loading opening is located in the housing of the tumble dryer on one end of the drum and the emptying opening is located on the opposite end. In order to be able to empty the tumble dryer conveniently and automatically, it is customary to start the entire dryer on the side opposite the emptying opening during the emptying process to lift. Due to the slanted position achieved in this way: the laundry is conveyed from the rotating drum through the opened emptying opening into a ready-made container.

Während des Kippvorganges muß eine relativ große Masse bewegt werden, weil das gasamte Gehäuse mit Ventilator, Heizregister und ähnlichem angehoben werden muß. Dies bedingt einen teuren Kippantrieb und hohen Energieverbrauch. Außerdem müssen die Anschlüsse für Strom, Dampf, Kondensat oder Wärmeträgerflüssigkeit beweglich ausgebildet sein, wodurch Störquellen entstehen. Auch muß während des Kippvorganges der Ventilatorabgangsstutzen von der bauseitigen Abluftleitung getrennt und der Ventilatormotor abgeschaltet werden.A relatively large mass has to be moved during the tilting process, because the gas-filled housing with fan, heating register and the like has to be raised. This requires an expensive tilt drive and high energy consumption. In addition, the connections for electricity, steam, condensate or heat transfer fluid must be designed so that they can cause interference. Also during the tilting process, the fan outlet connection must be separated from the on-site exhaust air line and the fan motor must be switched off.

Der Erfindung liegt die Aufgabe zugrunde, die Entleerung der Trommel des Wäschetrockners durch einfachere und sichere Mittel zu erreichen und den Festanschluß der Anschlußleitung ohne Schläuche einschließlich Abluftleitung ohne Kupplungsflansche zu ermöglichen. Außerdem sollen Be- und Entladeeinrichtungen am feststehenden Gehäuse montierbar sein.The invention has for its object to achieve the emptying of the drum of the dryer by simple and safe means and to allow the permanent connection of the connecting line without hoses including exhaust line without coupling flanges. In addition, loading and unloading devices should be mountable on the fixed housing.

Zur Lösung dieser Aufgabe, werden die im Patentanspruch angegebenen Maßnahmen vorgeschlagen.To solve this problem, the measures specified in the claim are proposed.

Es liegt auf der Hand, daß die Lagerung der Trommel auf einer Kippvorrichtung innerhalb des feststehenden Gehäuses mit einem billigeren Kippantrieb möglich ist und außerdem die beweglichen Anschlußleitungen wegen des feststehenden Versorgungsteils entfallen.It is obvious that the drum can be supported on a tilting device within the fixed housing with a cheaper tilting drive, and the movable connecting lines are also eliminated because of the fixed supply part.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:

  • Fig. 1 einen Schnitt durch den Wäschetrockner mit waagrecht liegender Innentrommel (Betriebszustand).
  • Fig. 2 einen Schnitt mit gekippter Innentrommel (Entleerungsvorgang).
In the drawing, an embodiment of the invention is shown. Show it:
  • Fig. 1 shows a section through the tumble dryer with the inner drum lying horizontally (operating state).
  • Fig. 2 shows a section with the inner drum tilted (emptying process).

Auf dem Gehäuse 1 des Wäschetrockners ist der Ventilator 2 und das Heizregister 4 zur Erwärmung der Trocknungsluft montiert. Das Heizregister 4 wird über die Vor- und Rücklaufleitung 5 bzw. 6 mit einem Wärmeträgermedium versorgt. Die Abluftleitung 3 ist fest mit dem Ventilator 2 verbunden.The fan 2 and the heating register 4 for heating the drying air are mounted on the housing 1 of the tumble dryer. The heating register 4 is supplied with a heat transfer medium via the supply and return line 5 or 6. The exhaust air line 3 is firmly connected to the fan 2.

Innerhalb des Gehäuses 1 ist die waagrecht angeordnete, über ihren Umfang gelochte Innentrommel 7 gelagert. Die an beiden Stirnseiten mindestens teilweise offene Innentrommel 7 wird über die Beschickungsöffnung 8 mit Wäsche beladen. An der gegenüberliegenden Stirnseite befindet sich die durch die Klappe 9 verschließbare Entleerungsöffnung 10. Die Innentrommel 7 ruht auf einem Lagergestell 11, welches um den Schwenkpunkt 12, welcher unterhalb der Einfüllöffnung 8 liegt, aus einer waagrechten Lage (Fig. 1) in eine zur Entleerungsöffnung 10 hin geneigten Lage (Fig. 2) abgekippt werden kann. Dies geschieht mittels des Antriebes 13, welcher z.B. aus einer senkrecht ausfahrbaren Schnecke 14 bestehen kann, auf welcher sich das Lagergestell 11 abstützt. Der Antrieb 13 ist so ausgebildet, daß die Schnecke 14 in vorgewählten Zwischenstufen stehen bleiben kann. Ein Antrieb über eine Hebel-Zylinder-Kombination oder anderes ist ebenfalls möglich.The horizontally arranged inner drum 7, which is perforated over its circumference, is mounted within the housing 1. The inner drum 7, which is at least partially open on both end faces, is loaded with laundry via the loading opening 8. On the opposite end face there is the emptying opening 10 which can be closed by the flap 9. The inner drum 7 rests on a storage rack 11 which moves around the pivot point 12, which is below the filling opening 8, from a horizontal position (FIG. 1) into an emptying opening 10 inclined position (Fig. 2) can be tilted. This is done by means of the drive 13, which e.g. can consist of a vertically extendable screw 14 on which the storage rack 11 is supported. The drive 13 is designed so that the screw 14 can remain in pre-selected intermediate stages. A drive via a lever-cylinder combination or other is also possible.

Bei waagrechter Trommelstellung und geschlossener Klappe 9 gemäß Fig. 1 wird durch die sich in der Innentrommel 7 befindliche Wäsche warme Trocknungsluft geleitet, während sich die Innentrommel 7 dreht. Nach Beendigung des Trocknungsvorganges wird die Klappe 9 geöffnet und bei drehender Innentrommel 7, die Schnecke 14 eingefahren, wodurch die Innentrommel an der Entleerungsseite abgesenkt wird und die getrocknete Wäsche aus der geneigten Innentrommel gefördert wird.When the drum position is horizontal and the flap 9 according to FIG. 1 is closed, warm drying air is passed through the laundry in the inner drum 7 while the inner drum 7 is rotating. After the drying process has ended, the flap 9 is opened and, with the inner drum 7 rotating, the screw 14 is retracted, as a result of which the inner drum on the emptying side is lowered and the dried laundry is conveyed out of the inclined inner drum.

Es ist zwar zweckmäßig nur die sich drehende Innentrommel 7 zu kippen, allerdings ist es auch denkbar und konstruktiv einfach durchzuführen, daß man die Innentrommel 7 einschließlich der diese umgebenden Außentrommel 15, oder sonstigen Ummantelung, welche mit dem Gehäuse 1 verbunden ist, in eine geneigte Lage zu bringen.It is advisable to tilt only the rotating inner drum 7, but it is also conceivable and structurally simple to carry out that the inner drum 7 including the outer drum 15 surrounding it, or other casing which is connected to the housing 1, is inclined Able to bring.
