Description

Die Erfindung betrifft eine Wäschebehandlungsmaschine insbesondere Wäschetrockner mit einer in einem Gehäuse drehbar gelagerten Trommel, einer mit einer Tür verschließbaren Beschickungsöffnung sowie einem Gebläse und einer Heizeinrichtung zur Erzeugung eines Prozessluftstromes, der im verriegelten Zustand der Tür durch die Trommel strömt und wobei die Heizeinrichtung aus einem Wärmetauscher besteht, der über Anschlüsse mit dem Warmwassernetz eines stationären Wärmeerzeugers verbunden ist.The invention relates to a laundry treatment machine, in particular tumble dryer with a drum rotatably mounted in a housing, a closable with a door feed opening and a fan and a heater for generating a process air stream, which flows in the locked state of the door through the drum and wherein the heater from a heat exchanger exists, which is connected via connections to the hot water network of a stationary heat generator.

Es ist bekannt, Heizungsenergie als Wärmequelle im Wäschetrockner zu benutzen, jedoch hat sich die Nutzung in der Praxis nicht durchgesetzt.It is known to use heating energy as a heat source in the tumble dryer, however, the use has not prevailed in practice.

So ist beispielsweise aus dem druckschriftlichen Stand der Technik, gemäß der EP 0 430 197 A1 , ein Haushaltswäschetrockner bekannt, mit einer von einem Motor angetriebenen Wäschetrommel, sowie einer außerhalb der Wäschetrommel angeordneten Einrichtung zur Erwärmung des Trockenluftstromes, der durch die Wäschetrommel mittels eines Gebläses gefördert wird. Der Wäschetrockner ist dabei mit einem Anschluss für das Warmassernetz eines Haushaltes versehen. Dabei besteht die Einrichtung zum Erwärmen der Trockenluft aus einem mit dem Warmwassernetz in Verbindung stehenden Wärmetauscher.For example, from the printed prior art, according to the EP 0 430 197 A1 , a household tumble dryer, with a driven by a motor drum laundry, and arranged outside the laundry drum means for heating the drying air flow, which is conveyed by the laundry drum by means of a blower. The tumble dryer is provided with a connection for the domestic hot water network. The device for heating the dry air consists of a heat exchanger connected to the hot water network.

Entsprechendes gilt auch für die US 6,941,680 , bei der ebenfalls beschrieben wird, dass über ein externes Wärmeerzeugungsaggregat die Wärme über einen Wärmetauscher abgegeben wird, der wiederum im Gerät selbst untergebracht ist. Vergleichbares ist auch aus der DE 694 08 125 T2 bekannt, wobei hier statt des Wärmetauschers Heizschlangen in Form eines Kastens um die Trommel gelegt sind, so dass über diese Heizschlangen, durch die das warme Wasser aus dem Netz strömt, die Wärme auf die Trommel abgegeben wird. Ein Gebläse ist vorgesehen, welches die warme Luft in der Trommel verwirbelt.The same applies to the US 6,941,680 in which it is also described that the heat is discharged via an external heat-generating unit via a heat exchanger, which in turn is housed in the device itself. Comparable is also from the DE 694 08 125 T2 known, in which case instead of the heat exchanger heating coils are placed in the form of a box around the drum, so that the heat is discharged to the drum via these heating coils, through which the warm water flows from the network. A fan is provided which swirls the warm air in the drum.

Der Einsatz von Primärenergie im Trommelraum von Wäschebehandlungsmaschinen verbessert die Energieeffizienz um ca. 50%. Die Nutzung der Heizungsanlage mit relativ kleinen Vorlauftemperaturen scheitert jedoch an einer ungeeigneten Wärmeübertragung, weil der Trocknungsprozess in zwei Stufen erfolgt. Dabei wird in der ersten Stufe der Luft in einem Wärmetauscher Wärme vom Heizungswasser übertragen. Der gekoppelte Wärmestoffaustausch wird erst in der zweiten Stufe vollzogen, wobei die erwärmte Luft in die Trommel strömt und die Wäsche erwärmt. Das ohnehin schon kleine Temperaturgefälle wird in den beiden Stufen aufgeteilt, wobei die die Wärme übertragenden Flächen relativ klein sind. Die übertragbare Wärme ist daher klein. Damit ist der Trocknungsprozess langsam, so dass keine sinnvolle Wäschetrocknung stattfinden kann.The use of primary energy in the drum space of laundry treatment machines improves energy efficiency by approx. 50%. However, the use of the heating system with relatively low flow temperatures fails due to an inappropriate heat transfer, because the drying process takes place in two stages. In this case, heat is transferred from the heating water in a heat exchanger in the first stage of the air. The coupled heat exchange is performed only in the second stage, wherein the heated air flows into the drum and heats the laundry. The already small temperature gradient is split in the two stages, whereby the heat transferring surfaces are relatively small. The transferable heat is therefore small. Thus, the drying process is slow, so that no meaningful laundry drying can take place.

Der Erfindung stellt sich somit die Aufgabe, eine Wäschebehandlungsmaschine und hier insbesondere einen Wäschetrockner dahingehend weiter zu bilden, der mit einer externen Wärmequelle verbunden ist, dass die Effizienz der Wärmenutzung besser ausgeschöpft wird.The invention thus has the object to further develop a laundry treatment machine and here in particular a tumble dryer, which is connected to an external heat source, that the efficiency of heat utilization is better utilized.

Erfindungsgemäß wird diese Aufgabe mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this object is achieved with the features of patent claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Bei der erfindungsgemäßen Lösung ergibt sich die übertragbare Wärme bei kleinen Temperaturgefällen zwischen der Vorlauftemperatur und der Umgebungstemperatur wesentlich effizienter, in dem eine einstufige Wärmeübertragung mit großen wärmeübertragenden Flächen zum Einsatz gebracht wird. Damit können mit dem Einsatz der Heizungswärme akzeptable Trocknungszeiten erzielt werden.In the solution according to the invention, the heat transferable at small temperature gradients between the flow temperature and the ambient temperature is much more efficient, in which a single-stage heat transfer is used with large heat transfer surfaces used. This can be achieved with the use of heating heat acceptable drying times.

Im ersten Trocknungsprozess wird die Wärme direkt in einer Stufe von dem Heizwasser auf die Wäsche übertragen. Dazu wird der direkte Kontakt der Wäsche mit der großen wärmeübertragenden Fläche des Trommelmantels genutzt. Im zweiten Trocknungsabschnitt sorgt eine geeignete Luftzuführung in der Trommel über die große wärmeübertragende Fläche des Trommelmantels für eine Trocknung der Wäsche in der Trommel. Weitere Vorteile sind, dass der Wäschetrockner wesentlich energieeffizienter ist. Zudem ist der Wäschetrockner sicherer, weil Brandgefahr weitgehend ausgeschlossen werden kann, wobei ein derartiger Wäschetrockner auch wesentlich langlebiger ist.In the first drying process, the heat is transferred directly in one stage from the heating water to the laundry. For this purpose, the direct contact of the laundry is used with the large heat transfer surface of the drum shell. In the second drying section provides a suitable air supply in the drum on the large heat transfer surface of the drum shell for drying the laundry in the drum. Other advantages are that the tumble dryer is much more energy efficient. In addition, the dryer is safer because fire risk can be largely excluded, with such a dryer is also much more durable.

Gemäß der Erfindung wird daher vorgeschlagen, dass die Trommel selbst als Wärmetauscher ausgebildet ist, wobei die Warmwasserführung unmittelbar über bzw. in der Trommelwand erfolgt. Die Warmwasserführung wird hierbei über in der Trommel angeordneten Rippen vorgenommen. Dabei erfolgt die Einspeisung des Warmwassers über einen als Rohrzapfen ausgebildeten Trommelzapfen, der mit einer im Trommelgehäuse angeordneten Rippe verbunden ist, die den Vorlauf bildet. Die Rückführung des Warmwassers wird hierbei über eine um den Rohrzapfen liegende Rohrhülse vorgenommen, die mit einer weiteren in der Trommel angeordneten Rippe verbunden ist und die den Rücklauf bildet. Dabei sind die den Vorlauf bildenden Rippen und die den Rücklauf bildenden Rippen über eine im Trommelöffnungsrand vorgesehene Rohrleitung verbunden. Somit wird ein Kreislauf in der Trommel geschaffen, der eine effiziente Wärmeabgabe ermöglicht, wobei die Wärmeübetragung über die Trommelwandung und/oder die Trommelrippen erfolgt.According to the invention it is therefore proposed that the drum itself is designed as a heat exchanger, wherein the hot water supply takes place directly above or in the drum wall. The hot water supply is carried out here via arranged in the drum ribs. In this case, the supply of hot water takes place via a drum pin formed as a tubular pin, which is connected to a rib arranged in the drum housing, which forms the flow. The return of the hot water is in this case carried out via a tubular sleeve lying around the pipe sleeve, which is connected to a further arranged in the drum rib and which forms the return. The flow forming ribs and the return ribs are connected via a provided in the drum opening edge pipe. Thus, a circuit is provided in the drum, which allows efficient heat dissipation, wherein the heat transfer via the drum wall and / or the drum ribs takes place.

In Weiterbildung der Erfindung ist hinter der Trommel ein Gebläse angeordnet, welches insbesondere den notwendigen Luftstrom erzeugt, der durch die Trommel strömt. In Weiterbildung der Erfindung kann dabei der erfindungsgemäße Wäschetrockner als Ablufttrockner oder aber auch als Kondenstrockner ausgebildet sein.In a further development of the invention, a fan is arranged behind the drum, which in particular generates the necessary air flow which flows through the drum. In a further development of the invention, the tumble dryer according to the invention can be designed as a vented dryer or else as a condenser dryer.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigt

Figur 1
eine geschnittene Seitenansicht des erfindungsgemäßen Wäschetrockners in der Ausbildung eines Kondenstrockners;
Figur 2
eine weitere Ausführungsform gemäß der Erfindung, wobei in der geschnittenen Seitenansicht der erfindungsgemäße Wäschetrockner als Ablufttrockner ausgebildet ist.
An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. It shows
FIG. 1
a sectional side view of the laundry dryer according to the invention in the formation of a Kondenstrockners;
FIG. 2
a further embodiment according to the invention, wherein in the sectional side view of the laundry dryer according to the invention is designed as a vented dryer.

Die Figuren 1 und 2 zeigen insbesondere Wäschebehandlungsmaschinen und zwar hier Wäschetrockner 1, mit einer in einem Gehäuse 2 drehbar gelagerten Trommel 3 sowie einer mit einer Tür 4a verschließbaren Beschickungsöffnung 4, wobei in dem Gehäuse 2 ein Gebläse 5 sowie eine Heizeinrichtung 6 zur Erzeugung eines Prozessluftstromes 7 vorgesehen ist, der insbesondere im verriegelten Zustand der Tür 4a durch die Trommel 3 strömt. Dabei ist die mit den Pfeilen dargestellte Heizeinrichtung 6 über Anschlüsse 8 mit dem Warmwassernetz eines stationären nicht näher dargestellten Wärmeerzeugers verbunden.The FIGS. 1 and 2 Show in particular laundry treatment machines and here tumble dryer 1, with a rotatably mounted in a housing 2 and a drum 3 with a door 4a closable feed opening 4, wherein in the housing 2, a fan 5 and a heater 6 is provided for generating a process air stream 7, the in particular in the locked state of the door 4a flows through the drum 3. The heater 6 shown with the arrows is connected via terminals 8 to the hot water network of a stationary heat generator, not shown.

Wie aus der Zusammenschau der Figur 1 und 2 zu erkennen ist, ist die Trommel 3 selbst als Wärmetauscher ausgebildet, wobei die Warmwasserführung unmittelbar bzw. in der Trommelwand 9 erfolgt. Aus der geschnittenen Darstellung der Figuren 1 und 2 wird auch deutlich, dass die Wasserführung über in der Trommel angeordneten Rippen 10.1 und 10.2 erfolgt. Die Einspeisung des Warmwassers erfolgt über einen als Rohrzapfen 11 ausgebildeten Trommelzapfen, der mit einer in der Trommel 3 angeordneten Rippe 10.1 verbunden ist, die den Vorlauf V bildet. Die Rückführung des Warmwassers erfolgt über eine um den Rohrzapfen 11 liegende Rohrhülse 12, die mit einer weiteren in der Trommel 3 angeordneten Rippe 10.2 verbunden ist, die den Rücklauf R bildet. In gestrichelter Darstellung angedeutet ist die Verbindung von Vorlauf V und Rücklauf R, wobei die den Vorlauf bildende Rippe 10.1 und die den Rücklauf R bildende Rippe 10.2 über eine im Trommelöffnungsrand 13 vorgesehene Rohrleitung 14 verbunden ist. Somit ergibt sich ein Kreislauf für das aus dem externen Erzeuger erwärmte Medium, welches somit effizient unmittelbar in der Trommel zum Einsatz und damit zur Wirkung kommt.As from the synopsis of FIG. 1 and 2 can be seen, the drum 3 itself is designed as a heat exchanger, wherein the hot water supply takes place directly or in the drum wall 9. From the cut representation of the FIGS. 1 and 2 It is also clear that the water flow takes place via ribs 10.1 and 10.2 arranged in the drum. The hot water is supplied via a drum pin formed as a pipe pin 11, which is connected to a rib 10. 1 arranged in the drum 3, which forms the feed line V. The return of the hot water takes place via a tubular sleeve 12 lying around the pipe sleeve 12, which is connected to a further arranged in the drum 3 rib 10.2, which forms the return R. Indicated in dashed lines is the connection of flow V and return R, wherein the rib 10.1 forming the flow and the rib R forming the return R are connected via a pipe 14 provided in the drum opening edge 13. This results in a circuit for the heated medium from the external generator, which thus efficiently used directly in the drum and thus to the effect.

Wie insbesondere aus den beiden Figuren 1 und 2 zu erkennen ist, befindet sich hinter der Trommel 3 das Gebläse 5, dessen erzeugter Volumenstrom 7a mit einem Pfeil angedeutet ist. Gemäß der Figur 1, die einen Kondenstrockner darstellt, ist der Kondensator 15 unterhalb der Trommel 3 angeordnet. Unterhalb des Kondensators 15 wird das anfallende Kondensat aufgefangen. Ferner kann mittels einer Leitung 16 aus den Anschlüssen 8 bzw. aus dem Verbindungsstück zwischen den Anschlüssen 8 und dem Rohrzapfen 11 / Rohrhülse 12 evtl. austretendes Leckagewasser abgeführt werden. Zu erkennen ist, dass die Prozessluftströmung 7 über die Trommel 3 vor der Türwand über den Kondensator 15 bis zu dem Gebläse 5 umläuft, so dass ein Prozessluftstrom 7 in der Trommel 3 erzeugt wird, der die Wärme, die aus der Trommelwand 9 kommt, umleitet.Especially from the two FIGS. 1 and 2 can be seen, is located behind the drum 3, the blower 5, the generated volume flow 7a is indicated by an arrow. According to the FIG. 1 , which constitutes a condenser dryer, the condenser 15 is arranged below the drum 3. Below the condenser 15, the resulting condensate is collected. Furthermore, 12 leaking leakage water can be removed by means of a line 16 from the terminals 8 and from the connecting piece between the terminals 8 and the pipe pin 11 / tube sleeve. It can be seen that the process air flow 7 via the drum 3 in front of the door wall via the condenser 15 to the fan 5 circulates, so that a process air stream 7 is generated in the drum 3, which diverts the heat that comes from the drum wall 9.

Figur 2 stellt hier einen Ablufttrockner dar, wobei hier das Gebläse 3 von außen her Frischluft ansaugt und diese durch die Trommel 3 führt, gemäß der Pfeilrichtung und über ein Abluftrohr 17 an die Umgebung wieder abgibt. FIG. 2 Here represents an exhaust air dryer, in which case the fan 3 sucks fresh air from the outside and this leads through the drum 3, according to the direction of the arrow and via an exhaust pipe 17 to the environment again releases.

Die genannte Art der Wärmeeinspeisung in die Trommel ist besonders gut für Wärmepumpentrockner geeignet, weil bei hierbei üblicherweise die Luft nicht so stark erwärmt wird.The aforementioned type of heat input into the drum is particularly well suited for heat pump dryer, because in this case usually the air is not heated as much.
