Description

Die Erfindung betrifft ein Wäschetrocknungsgerät mit einer Auffangkammer zum Auffangen von Flüssigkeit, mit einem herausnehmbaren Sammelbehälter und mit folgenden weiteren Merkmalen: Der herausnehmbare Sammelbehälter weist ein Flüssigkeitsreservoir zum Sammeln von Flüssigkeit auf sowie einen integrierten, als beidseitig offene Röhre ausgeführten Verbindungskanal, der gleitbar in einer röhrenartigen seitlichen Fortsetzung des herausnehmbaren Sammelbehälters entlang einer Längsachse der röhrenartigen seitlichen Fortsetzung angeordnet ist. Die Flüssigkeit ist insbesondere beim Trocknen von Wäsche entstandenes Kondenswasser.The invention relates to a laundry drying apparatus having a collecting chamber for collecting liquid, with a removable collecting container and with the following further features: The removable collecting container has a liquid reservoir for collecting liquid and an integrated, designed as a tube open on both sides connecting channel slidably in a tubular lateral continuation of the removable collecting container along a longitudinal axis of the tubular lateral continuation is arranged. The liquid is in particular the drying of laundry caused condensation.

Ein solches Wäschetrocknungsgerät geht hervor aus der EP 1 914 340 A1 .Such a clothes dryer emerges from the EP 1 914 340 A1 ,

Wäschetrocknungsgeräte können als Wäschetrockner oder als Waschtrockner ausgeführt sein, wobei unter dem Begriff Wäschetrockner ein Gerät verstanden wird, mittels dessen Wäsche lediglich getrocknet werden kann, während unter dem Begriff Waschtrockner ein Gerät verstanden wird, mittels dessen Wäsche außer getrocknet auch (vor dem Trocknen) gewaschen werden kann. Auffangkammer und Sammelbehälter sind im in das Wäschetrocknungsgerät eingesetzten Zustand des Sammelbehälters hydraulisch miteinander verbunden, so dass das Kondenswasser von der Auffangkammer zum Sammelbehälter gelangen kann.Laundry drying equipment can be designed as a tumble dryer or as a washer dryer, the term dryer is understood a device by means of which laundry can only be dried, while the term washer dryer means a device washed by means of which laundry except dried (before drying) can be. Collecting chamber and collecting container are hydraulically connected to one another in the state of the collecting container inserted into the laundry drying device, so that the condensed water can pass from the collecting chamber to the collecting container.

Problem bei einem solchen Wäschetrocknungsgerät ist, dass sich im Kondenswasser enthaltenes Schwemmgut wie z. B. Wäscheflusen im Übergangsbereich von der Auffangkammer zum Sammelbehälter anlagern kann, wodurch zum einen bei Bereichen der Auffangkammer wie auch des Sammelbehälters, die bei einem Herausnehmen des Sammelbehälters aus dem Wäschetrocknungsgerät umgehend wasserdicht abgedichtet werden sollen, um ein ggf. auch nur kurzzeitig auftretendes Auslaufen des Kondenswassers zu verhindern, ein Teil dieses Schwemmguts die Dichtwirkung beim Trennen des Sammelbehälters von der Auffangkammer verschlechtern bis aufheben kann. Dies wird häufig auch noch dadurch gefördert, dass der Übergang zwischen Auffangkammer und Sammelbehälter in seinem Verlauf winkelig und/oder verschlungen ausgeführt ist, was bekanntlich einen negativen Einfluß auf die Fließgeschwindigkeit von Flüssigkeiten hat. Eine niedrige Fließgeschwindigkeit wiederum beeinflusst das Fließverhalten des Schwemmguts negativ mit der Folge, dass sich dieses leichter insbesondere an den genannten Problemzonen anlagern kann mit den bereits geschilderten nachteiligen Folgen.Problem with such a laundry dryer is that contained in the condensation alluvial such. B. Wäscheflusen can accumulate in the transition region of the collecting chamber to the collecting container, which on the one hand in areas of the collecting chamber as well as the collecting container, which should be sealed watertight at a removal of the sump from the laundry dryer to a possibly even briefly occurring leakage of the Condensate water to prevent a part of this Schwemmguts the sealing effect when separating the collection of the collecting chamber worsen to pick up. This is often also promoted by the fact that the transition between the collecting chamber and collecting container is executed in its course angular and / or entangled, which is known to have a negative influence on the flow rate of Has fluids. A low flow rate, in turn, negatively influences the flow behavior of the Schwemmguts negative, with the result that this can easily attach particular to the said problem areas with the already described adverse consequences.

Es ist Aufgabe der Erfindung, ein Wäschetrocknungsgerät zu schaffen, bei dem sowohl die Dichtwirkung zwischen seinen einzelnen Teilen als auch der Durchfluss von Kondenswasser zwischen diesen Teilen verbessert sind.It is an object of the invention to provide a clothes drying apparatus in which both the sealing effect between its individual parts and the flow of condensed water between these parts are improved.

  • wohingegen bei in das Wäschetrocknungsgerät eingesetztem herausnehmbarem Sammelbehälter die Klappen geöffnet sind und über den integrierten Verbindungskanal hinweg eine hydraulisch nutzbare Verbindung zwischen der Auffangkammer und dem herausnehmbaren Sammelbehälter besteht.
To achieve the object, therefore, a laundry drying apparatus is provided with a collecting chamber for collecting liquid, with a removable collecting container and with the following further features:
  • the removable sump comprises a liquid reservoir for collecting liquid and an integral, open-ended tube communicating channel slidably disposed in a tubular lateral continuation of the removable sump along a longitudinal axis of the tubular lateral continuation;

Fig. 1 zeigt als Teile eines Wäschetrocknungsgeräts in Form eines Längsschnitts die wesentlichen Teile einer Auffangkammer 2 und die wesentlichen Teile eines aus dem Wäschetrocknungsgerät herausnehmbaren Sammelbehälters 3, wobei in dieser Darstellung der Sammelbehälter 3 als in das Wäschetrocknungsgerät eingesetzt gezeigt ist. Zur optisch leichteren Erkennbarkeit des Sammelbehälters 3 ist dessen äußere Umrandung (soweit dargestellt) mit einer etwas größeren Strichdicke gezeichnet als die restlichen dargestellten Teile des Wäschetrocknungsgeräts. Fig. 1 shows as parts of a laundry drying apparatus in the form of a longitudinal section the essential parts of a collecting chamber 2 and the essential parts of a removable from the laundry drying device collecting container 3, wherein in this illustration the collecting container 3 is shown as inserted into the laundry drying apparatus. For optically easier recognizability of the collecting container 3, its outer border (as far as shown) is drawn with a slightly greater line thickness than the remaining parts of the laundry drying device shown.

Der Sammelbehälter 3 weist ein nur marginal dargestelltes Flüssigkeitsreservoir 33 sowie einen integrierten Verbindungskanal 1 auf. Der integrierte Verbindungskanal 1 ist in einer röhrenartigen seitlichen Fortsetzung 4 des herausnehmbaren Sammelbehälters 3 angeordnet, und zwar entlang einer Längsachse L der röhrenartigen seitlichen Fortsetzung 4. Er ist weiterhin entlang der Längsachse L der röhrenartigen seitlichen Fortsetzung 4 in und aus Richtung der Auffangkammer 2 verschiebbar.The collecting container 3 has an only marginally illustrated liquid reservoir 33 and an integrated connection channel 1. The integrated connection channel 1 is arranged in a tubular lateral continuation 4 of the removable collecting container 3, along a longitudinal axis L of the tubular lateral continuation 4. It is further displaceable along the longitudinal axis L of the tubular lateral continuation 4 in and out of the direction of the collecting chamber 2.

Im in das Wäschetrocknungsgerät eingesetzten Zustand des herausnehmbaren Sammelbehälters 3 besteht über das Innere des integrierten Verbindungskanals 1, der beidseitig offen ist, zwischen der Auffangkammer 2 und dem herausnehmbaren Sammelbehälter 3, und insbesondere dessen Flüssigkeitsreservoir 33, eine hydraulisch nutzbare Verbindung, über die in der Auffangkammer 2 sich ansammelnde bzw. angesammelte Flüssigkeit wie z. B. beim Trocknen von Wäsche anfallendes Kondenswasser in das Flüssigkeitsreservoir 33 des Sammelbehälters 3 gelangen bzw. transportiert werden kann.In the state of the removable collecting container 3 inserted into the laundry drying device, there is a hydraulically usable connection via the interior of the integrated connecting channel 1, which is open on both sides, between the collecting chamber 2 and the removable collecting container 3, and in particular its liquid reservoir 33, via the collecting chamber 2 accumulating or accumulated liquid such. B. in the drying of laundry accumulating condensate in the liquid reservoir 33 of the collecting container 3 arrive or can be transported.

Der Sammelbehälter 3 weist darüber hinaus auch eine unter einer gegebenen Vorspannung stehende Klappe 7 auf, die im herausgenommenen Zustand des Sammelbehälters 3 dessen Flüssigkeitsreservoir 33 gegenüber der röhrenartigen seitlichen Fortsetzung 4 des Sammelbehälters 3 und dem darin befindlichen integrierten Verbindungskanal 1 hydraulisch abdichtet, was nachstehend noch näher erläutert wird. Analog dazu weist auch die Auffangkammer 2 eine weitere, ebenfalls unter einer gegebenen Vorspannung stehende Klappe 7' auf, die im herausgenommenen Zustand des Sammelbehälters 3 (und somit auch des Verbindungskanals 1) eine durch das Herausnehmen frei werdende Öffnung der Auffangkammer 2 hydraulisch abdichtet.The collecting container 3 also has a standing under a given bias flap 7, the liquid reservoir 33 in the removed state of the collecting container 3 against the tubular lateral continuation 4 of the collecting container 3 and the integrated connection channel 1 therein hydraulically seals, which will be even closer is explained. Similarly, also has the collecting chamber 2 a further, also under a given bias flap 7 ', which in the removed state of the collecting container 3 (and thus also the connecting channel 1) hydraulically seals an opening of the collecting chamber 2 released by the removal.

Dabei ist es hinsichtlich jeder einzelnen der beiden Klappen 7, 7' erfindungsgemäss vorgesehen, dass sie nicht nur in einem Zustand, in dem die jeweilige der beiden Klappen 7, 7' ihre abdichtende Funktion (noch) nicht ausübt (mit anderen Worten: in dem die jeweilige Öffnung nicht hydraulisch abgedichtet ist), sich unter einer Vorspannung befindet, sondern dass sie sich auch in dem Zustand, in dem sie die ihr jeweils zugedachte abdichtende Funktion ausübt, immer noch unter einer (restlichen) ebenfalls gegebenen Vorspannung befindet. Damit kann sie dann nämlich einen gewissen Anpressdruck auf die jeweilige abzudichtende Öffnung ausüben und somit die gewünschte Abdichtung mit höherer Wahrscheinlichkeit sicherstellen. Diese Vorspannung kann z. B. mittels einer Feder oder eines Federstahls erzeugt sein. Sie kann aber auch mittels eines Bimetalls erzeugt sein.It is provided according to the invention with respect to each one of the two flaps 7, 7 ', not only in a state in which the respective one of the two flaps 7, 7' (yet) does not perform its sealing function (in other words: in the the respective opening is not hydraulically sealed), is under a bias, but that it is still in the state in which it performs their respective intended sealing function, under a (remaining) also given bias. Thus, they can then exert a certain contact pressure on the respective opening to be sealed and thus ensure the desired seal with a higher probability. This bias can z. B. be generated by means of a spring or a spring steel. But it can also be generated by means of a bimetal.

Besonders vorteilhaft ist es, wenn die röhrenartige seitliche Fortsetzung 4 des herausnehmbaren Sammelbehälters 3 ein Stoppelement 9, einen Anschlag 51 sowie eine den integrierten Verbindungskanal 1 in einem gegebenen Abschnitt desselben radial umfassende Feder 5 umfasst, die zwischen dem Anschlag 51 und einem an einer Außenwand des integrierten Verbindungskanals 1 radial zum integrierten Verbindungskanal 1 angeordneten weiteren Anschlag 52 angeordnet ist.It is particularly advantageous if the tube-like lateral continuation 4 of the removable collecting container 3 comprises a stop element 9, a stop 51 and a spring 5 which radially surrounds the integrated connecting channel 1 in a given section and which is located between the stop 51 and one on an outer wall of the housing integrated connection channel 1 radially to the integrated connection channel 1 arranged further stop 52 is arranged.

Bei einer solchen vorteilhaften Anordnung, die in Fig. 1 gezeigt ist, geschieht beim Herausnehmen und Wiedereinsetzen des herausnehmbaren Sammelbehälters 3 Folgendes: Im eingesetzten Zustand des Sammelbehälters 3, der in Fig. 1 dargestellt ist, befindet sich der integrierte Verbindungskanal 1 in einem hinsichtlich der Längsachse L insoweit austarierten Zustand, als sich das eine Ende des integrierten Verbindungskanals 1 in das Flüssigkeitsreservoir 33 des Sammelbehälters 3 erstreckt und als sich das dazu entgegen gesetzte Ende des integrierten Verbindungskanals 1 in die Auffangkammer 2 hinein erstreckt. Die beiden Klappen 7 und 7' sind dabei durch den integrierten Verbindungskanal 1 nach (z. B.) oben weggedrückt, wie aus Fig. 1 ersichtlich, so dass sich in der Auffangkammer 2 vorhandene Flüssigkeit, sei es aufgrund von seiner Flüssigkeitshöhe oder sei es aufgrund von Unterstützungsmaßnahmen wie z. B. Pumpen, durch den integrierten Verbindungskanal 1 hindurch in den herausnehmbaren Sammelbehälter 3 und dort in dessen Flüssigkeitsreservoir 33 bewegen kann. Gleichzeitig bewirken die beiden Klappen 7 und 7' insbesondere dann, wenn sie so ausgelegt sind, dass sie in etwa gleich große Federkräfte auf das ihnen jeweils zugeordnete Ende des integrierten Verbindungskanals 1 ausüben, den vorstehend genannten austarierten Zustand des integrierten Verbindungskanals 1, ggf. unter Berücksichtigung der von der Feder 5 ausgeübten Federkraft.In such an advantageous arrangement, in Fig. 1 is shown, the following occurs when removing and reinserting the removable collecting container 3: In the inserted state of the collecting container 3, the in Fig. 1 is shown, the integrated connection channel 1 is in a respect to the longitudinal axis L so far tared state, as the one end of the integrated connection channel 1 extends into the liquid reservoir 33 of the collecting container 3 and as the opposite end of the integrated connection channel 1 in the Receiving chamber 2 extends into it. The two flaps 7 and 7 'are pushed away upward through the integrated connection channel 1 (eg), as shown Fig. 1 apparent, so that in the collecting chamber 2 existing liquid, whether due to its liquid level or be it due to support measures such. As pumps, through the integrated connection channel 1 through the removable collection container 3 and there in the liquid reservoir 33 can move. At the same time, the two flaps 7 and 7 'in particular when they are designed so that they are approximately equal spring forces on their respective associated end of the integrated connection channel. 1 exercise, the aforementioned tared state of the integrated connection channel 1, possibly taking into account the force exerted by the spring 5 spring force.

Bei einem Herausnehmen des herausnehmbaren Sammelbehälters 3 aus dem Wäschetrocknungsgerät geschieht nun Folgendes: der herausnehmbare Sammelbehälter 3 (zunächst angeordnet wie in der Ausführungsform nach Fig. 1) wird in Richtung nach rechts wegbewegt. Aufgrund des axial längs der Längsachse L herrschenden Kräftegleichgewichts zwischen den beiden Klappen 7, 7' bewirkt das Herausnehmen ein bzgl. seiner bisherigen lokalen Anordnung innerhalb des Wäschetrocknungsgeräts quasistationäres Gleiten des integrierten Verbindungskanals 1 innerhalb der röhrenartigen seitlichen Fortsetzung 4 des herausnehmbaren Sammelbehälters 3 nach links bis zu einem Punkt, an dem das Stoppelement 9 am weiteren Anschlag 52 anstößt (in Fig. 1 ist diese Position des weiteren Anschlags 52 gestrichelt dargestellt), wobei sich die Feder 5 in ihrer Länge ausdehnt. Dadurch wiederum hat sich aber der integrierte Verbindungskanal 1 insgesamt so in Richtung linksseitiges Ende der röhrenartigen seitlichen Fortsetzung 4 verschoben, dass sein rechtes Ende, das ja bislang bis in das Flüssigkeitsreservoir 33 hineingereicht hat, nunmehr innerhalb der röhrenartigen seitlichen Fortsetzung 4 an einer Stelle endet, die in Fig. 1 durch eine gestrichelte Linie angedeutet und mit dem Bezugszeichen 6 versehen ist. Bei einem weiteren Herausnehmen des herausnehmbaren Sammelbehälters 3 aus dem Wäschetrocknungsgerät verbleibt dann der integrierte Verbindungskanal 1 stationär in dieser Position. Dabei zieht sich der integrierte Verbindungskanal 1 seitlich aus der Auffangkammer 2 zurück, so dass sich in Folge die weitere Klappe 7', die an der Auffangkammer 2 angeordnet ist, schließt und somit einen Flüssigkeitsfluss in Richtung auf den entnehmbaren Sammelbehälter 3 unterbindet, so dass die Auffangkammer 2 mittels der weiteren Klappe 7' hydraulisch abgedichtet ist.When removing the removable collecting container 3 from the laundry drying device, the following now happens: the removable collecting container 3 (initially arranged as in the embodiment according to FIG Fig. 1 ) is moved away to the right. Due to the force equilibrium between the two flaps 7, 7 ', which prevails axially along the longitudinal axis L, the removal brings about a quasi-stationary sliding of the integrated connecting channel 1 within the tubular lateral continuation 4 of the removable collecting container 3 to the left, up to its previous local arrangement within the laundry drying apparatus a point at which the stop member 9 abuts the further stop 52 (in Fig. 1 this position of the further stop 52 is shown in dashed lines), wherein the spring 5 expands in length. As a result, however, the integrated connecting channel 1 has shifted overall in the direction of the left-hand end of the tubular lateral continuation 4 in such a way that its right end, which so far has penetrated into the liquid reservoir 33, now ends within the tubular lateral continuation 4 at one point, in the Fig. 1 indicated by a dashed line and provided with the reference numeral 6. In a further removal of the removable collection container 3 from the laundry drying device then the integrated connection channel 1 remains stationary in this position. In this case, the integrated connection channel 1 retracts laterally from the collecting chamber 2, so that in succession, the further flap 7 ', which is arranged on the collecting chamber 2, closes and thus prevents liquid flow in the direction of the removable collecting container 3, so that the Collection chamber 2 by means of the further flap 7 'is hydraulically sealed.

Bei einem Wiedereinsetzen des herausnehmbaren Sammelbehälters 3 in das Wäschetrocknungsgerät drückt bei nach wie vor geschlossener Klappe 7 der integrierte Verbindungskanal 1 zunächst die weitere Klappe 7' auf, wodurch eine hydraulisch nutzbare Verbindung zwischen der Auffangkammer 2 und dem integrierten Verbindungskanal 1 entsteht. Beim Fortsetzen des Wiedereinsetzvorgangs stößt dann der integrierte Verbindungskanal 1 an eine in der Auffangkammer 2 angeordnete Begrenzungsrippe 8 an, die ein weiteres Eindringen des integrierten Verbindungskanals 1 in die Auffangkammer 2 unterbindet. Bei einem weiteren Fortsetzen dieses Vorgangs ändert sich infolgedessen die Position des integrierten Verbindungskanals 1 innerhalb der röhrenartigen seitlichen Fortsetzung 4 des herausnehmbaren Sammelbehälters 3 dahingehend, dass der integrierte Verbindungskanal 1 in Richtung des Flüssigkeitsreservoirs 33 geschoben wird und dabei die Klappe 7 aufstößt. Damit ist die ursprünglich bereits bestehende hydraulisch nutzbare Verbindung zwischen der Auffangkammer 2 und dem herausnehmbaren Sammelbehälter 3 wieder hergestellt; der Wiedereinsetzvorgang ist abgeschlossen.When re-inserting the removable collecting container 3 in the laundry drying device presses when still closed flap 7 of the integrated connection channel 1, the first further flap 7 ', whereby a hydraulically usable connection between the collecting chamber 2 and the integrated connection channel 1 is formed. When resuming the re-insertion process then abuts the integrated connection channel 1 to a arranged in the collecting chamber 2 limiting rib 8, which prevents further penetration of the integrated connection channel 1 into the collecting chamber 2. As a result, continuing this process will change the position of the integrated connection channel 1 within the tubular lateral continuation 4 of the removable collecting container 3 in such a way that the integrated connecting channel 1 is pushed in the direction of the liquid reservoir 33 and thereby the flap 7 abuts. Thus, the originally existing hydraulically usable connection between the collecting chamber 2 and the removable collecting container 3 is restored; the reinstallation process is complete.

Aufgrund der erfindungsgemässen Ausgestaltung des integrierten Verbindungskanals 1 als beidseitig offene, gerade Röhre bietet dieser dem Schwemmgut, das beim Betrieb des Wäschetrocknungsgeräts in der durch ihn fließenden Flüssigkeit enthalten ist, einen optimal geringen Widerstand, so dass die Gefahr des Bildens von Anlagerungen am Verbindungskanal und/oder an den Klappen, wie eingangs geschildert, minimiert ist. Und selbst in einem Fall, in dem sich doch Ablagerungen in ihm angesammelt haben sollten, so lässt sich dieses Malheur ebenfalls relativ einfach beseitigen, indem man den integrierten Verbindungskanal in herausgenommenem Zustand des herausnehmbaren Sammelbehälters in die röhrenartige seitliche Fortsetzung des herausnehmbaren Sammelbehälters manuell hineindrückt, dadurch die eine Klappe 7 öffnet und daraufhin den Verbindungskanal kräftig durchspült.Due to the inventive design of the integrated connection channel 1 as a straight tube open on both sides this offers the Schwemmgut that is contained in the operation of the laundry dryer in the liquid flowing through it, an optimally low resistance, so that the risk of forming deposits on the connecting channel and / or at the flaps, as described above, is minimized. And even in a case in which deposits should have accumulated in it, this mishap can also be removed relatively easily by manually pushing the integrated connecting channel in the removed state of the removable collecting container into the tubular lateral continuation of the removable collecting container, thereby which opens a flap 7 and then thoroughly flushes through the connecting channel.

Fig. 2 zeigt eine vorteilhafte Ausführungsform der einen Klappe 7, nach der aber auch die andere der beiden Klappen 7, 7' gestaltet sein kann: dabei ist die Feder der Klappe 7 als Schraubenfeder 11 ausgeführt, die zentral mittig an der Klappe 7 angreift. Dadurch ergibt sich eine gleichmäßige Verteilung des Anpressdrucks auf die Klappe 7. Dies ist insbesondere deshalb besonders günstig, weil die Klappen 7 und 7' erfindungsgemäss eine umlaufende Dichtlippe aufweisen, wie in Fig. 2 gezeigt, Fig. 2 shows an advantageous embodiment of a flap 7, but after the other of the two flaps 7, 7 'can be designed: while the spring of the flap 7 is designed as a helical spring 11 which centrally acts on the flap 7 centrally. This results in a uniform distribution of the contact pressure on the flap 7. This is particularly advantageous because the flaps 7 and 7 'according to the invention have a circumferential sealing lip, as in Fig. 2 shown,

denn dann kann sich der Anpressdruck gleichmäßig auf die gesamte Dichtlippe 12 verteilen, was wiederum die Dichtwirkung der jeweiligen Klappe 7, 7' optimiert.because then the contact pressure can be evenly distributed over the entire sealing lip 12, which in turn optimizes the sealing effect of the respective flap 7, 7 '.
