Description

Die Erfindung betrifft einen Wäschetrockner mit einem Gehäuse und einem Behandlungsraum zur Aufnahme von Trockengut, und mit einer Einrichtung zum Kondensieren von Feuchtigkeit aus dem Trockengut, welche einen Prozessluftstrom erzeugt, in dessen Strömungskanal ein Filtereinsatz angeordnet ist, wobei der Filtereinsatz von außen über eine in der Frontwand des Gehäuses angeordnete Revisionsklappe zugänglich ist, und wobei der Filtereinsatz zum formschlüssigen Einsatz im Strömungskanal Hülsenelemente aufweist, die auf im Strömungskanal angeordnete Zapfenelemente im eingesetzten Zustand steckbar sind, wobei zur korrekten Montage des Filtereinsatzes ein Überwachungselement vorgesehen ist (siehe US-A-2006 00 37 213 ).The invention relates to a tumble dryer with a housing and a treatment space for receiving dry material, and with a device for condensing moisture from the dry material, which generates a process air flow, in the flow channel a filter insert is arranged, wherein the filter insert from the outside via a in the Front wall of the housing arranged inspection flap is accessible, and wherein the filter insert for positive engagement in the flow channel sleeve members which are plugged into arranged in the flow channel pin elements in the inserted state, wherein for the correct mounting of the filter insert a monitoring element is provided (see US-A-2006 00 37 213 ).

Auf dem Stand der Technik gemäß der WO 2005/090669 A2 ist bereits ein von außen über eine in der Frontwand des Gehäuses angeordnete Revisionsklappe zugänglicher Filtereinsatz im Strömungskanal bekannt. Dieser bekannte Filtereinsatz befindet sich im Strömungskanal in einer Kassette, die wie eine Schublade in den Gang durch die Revisionsklappe eingeschoben werden kann, so dass die Prozessluft über den Filtereinsatz strömt, der vor dem Wärmetauscher angeordnet ist, der zum Schutz gegen Verflusung des Wärmetauschers vorgesehen ist. Aufgrund der Bauart zu herkömmlichen Kondensattrockner kann der Wärmetauscher nicht entnommen und gereinigt werden. Aus diesem Grund muss sichergestellt werden, dass bei fehlendem Filtereinsatz der Wärmetauscher im Betrieb nicht von Prozessluft durchströmt wird. Die bisherige Lösung basiert auf den Einsatz eines Magneten, der als Überwachungselement für den Einsatz des Filters fungiert. Für die Herstellung eines Magneten bedarf es der Verwendung von sogenannten Selten-Erden. Der Kaufpreis dieser Magnete ist stark gestiegen, was die Herstellungskosten nachteilig beeinflusst. Denn bei den bisherigen Wärmepumpentrocknern wird eine aufwendige Elektronik verwendet, die den korrekten Einbau des Filtereinsatzes überwacht.In the prior art according to the WO 2005/090669 A2 is already known from the outside via a arranged in the front wall of the housing access door filter insert in the flow channel known. This known filter element is located in the flow channel in a cassette which can be inserted like a drawer in the passage through the access door, so that the process air flows through the filter insert, which is arranged in front of the heat exchanger, which is provided to protect against leaching of the heat exchanger , Due to the design of conventional condensate dryers, the heat exchanger can not be removed and cleaned. For this reason, it must be ensured that if there is no filter insert, the heat exchanger does not flow through process air during operation. The previous solution is based on the use of a magnet, which acts as a monitoring element for the use of the filter. The production of a magnet requires the use of so-called rare earths. The purchase price of these magnets has risen sharply, which adversely affects the manufacturing cost. Because in the previous heat pump dryers a complex electronics is used, which monitors the correct installation of the filter cartridge.

Der Erfindung stellt sich somit das Problem, einen Wäschetrockner derart weiterzubilden, bei dem die Überwachung des Filtereinsatzes sich wesentlich kostengünstiger realisieren lässt.The invention thus raises the problem of developing a tumble dryer in such a way that the monitoring of the filter cartridge can be implemented much more cost-effectively.

Erfindungsgemäß wird dieses Problem mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichten Vorteile bestehen nun darin, dass durch den Einsatz bzw. die Bereitstellung einer Mechanik das Problem gelöst wird, die ein Schließen der Revisionsklappe bei demontiertem Filtereinsatz verhindert. In der Ausgangsposition sitzt der Filtereinsatz im Gerät und die Revisionsklappe ist geschlossen. Nach dem Öffnen der Revisionsklappe und dem Herausnehmen des Filtereinsatzes wird ein federbelasteter Stift in die vordere Endposition geschoben und verriegelt selbstständig. Wird versucht in diesem Zustand die Revisionsklappe ohne den Filtereinsatz zu schließen, dann trifft diese gegen den verriegelten Stift und kann nicht geschlossen werden. Durch Einsetzen des Filtereinsatzes wird der Stift entriegelt und in seine hintere Endposition geschoben und die Revisionsklappe kann wieder geschlossen werden. Aufgrund dieser Ausbildung wird eine rein mechanische Überwachung bereitgestellt, die hinsichtlich ihrer Herstellungskosten wesentlich günstiger ausfällt.The advantages achieved by the invention are now that the use or the provision of a mechanism, the problem is solved, the closing of the Inspection flap with disassembled filter insert prevented. In the starting position, the filter insert is located in the device and the inspection flap is closed. After opening the inspection flap and removing the filter element, a spring-loaded pin is pushed into the front end position and locks automatically. If an attempt is made to close the inspection flap without the filter insert in this state, then it hits against the locked pin and can not be closed. By inserting the filter insert, the pin is unlocked and pushed into its rear end position and the access panel can be closed again. Due to this design a purely mechanical monitoring is provided, which is much cheaper in terms of their production costs.

Gemäß der Erfindung wird hierzu vorgeschlagen, dass als Überwachungselement zur korrekten Montage wenigstens einer der Zapfenelemente als Sperrmittel ausgebildet ist, welches bei fehlendem Filtereinsatz im Strömungskanal ein Verschließen der Revisionsklappe unterbindet. Hierbei besteht das Sperrmittel aus einem am Zapfenelement angeordneten teleskopierbaren Stift, der gegen die Wirkung einer Feder verschiebbar am Zapfenelement angeordnet ist. Der Stift als solches wirkt hierbei mit einem Riegelelement zusammen, welches den Stift im teleskopiertem Zustand sperrt. Ist also der Stift ausgefahren, wird er von dem Riegelelement gegen ein selbsttätiges Zurückschieben gesperrt. Wird nun der Filtereinsatz in die Öffnung des Strömungskanals eingesetzt, so wird das Riegelelement durch Aufstecken des am Filtereinsatz angeordneten Hülsenelementes entriegelt, so dass dann die Revisionsklappe behinderungsfrei verschlossen werden kann.According to the invention, it is proposed for this purpose that is designed as a monitoring element for correct mounting of at least one of the pin elements as a blocking means, which prevents closure of the access door in the absence of filter insert in the flow channel. Here, the blocking means consists of a pin element arranged on the telescopic pin, which is arranged against the action of a spring displaceable on the pin member. The pin as such acts in this case with a locking element which locks the pin in the telescoped state. So if the pin is extended, it is locked by the locking element against an automatic pushing back. Now, if the filter insert is inserted into the opening of the flow channel, the locking element is unlocked by attaching the sleeve element arranged on the filter element, so that then the access door can be closed without obstruction.

In Weiterbildung des Riegelelementes umfasst dieses ein quer zur Verschieberichtung des Stiftes beweglich angeordnetes Nockenelement. Das Nockenelement als solches ist gegen die Wirkung der Schwerkraft in die entriegelnde Lage bringbar. Der Stift bewegt sich bei Entnahme des Filtereinsatzes in die vordere Endlage wobei das Nockenelement schwerkraftbelastet in die Sperrposition fällt. Die Revisionsklappe lässt sich nicht mehr schließen. Durch Einsetzen des Filtereinsatzes wird das Nockenelement angehoben und gibt den Verfahrweg für den Stift wieder frei.In a further development of the locking element, this comprises a transversely to the direction of displacement of the pin movably arranged cam member. As such, the cam element can be brought into the unlocking position against the action of gravity. When the filter insert is removed, the pin moves into the front end position, with the cam element falling into the blocking position with gravitational force. The access panel can not be closed anymore. By inserting the filter insert, the cam element is raised and releases the travel path for the pin again.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung kann hierbei auch das Riegelelement als ein Blattfederelement ausgestaltet sein, welches als Federstreifen am Zapfenelement wippenartig befestigt ist. Gemäß der zweiten Variante lagert in einer Kunststoffführung ein federbelasteter Metallstift. Dieser Stift bewegt sich bei Entnahme des Einsatzfilters in die vordere Endlage und eine Blechfeder, die mit der Kunststoffführung verbunden ist, rastet in einem Absatz des Stiftes ein und verriegelt diesen. Die Revisionsklappe lässt sich nicht mehr schließen. Durch Einsetzen des Filtereinsatzes wird die Blechfeder gebogen und gibt dadurch den Verfahrweg für den Stift wieder frei. Hierzu ist das Riegelelement, welches als Federstreifen ausgebildet ist, am Zapfenelement wippenartig befestigt. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung weist der Federstreifen in seinem mittleren Erstreckungsbereich eine nach außen weisende Ausformung auf, die eine Art Noppenführung bildet. Der Federstreifen weist an seinem freien Ende einen zum verschiebbaren Stift weisenden Hakenbereich auf, der im verriegelten Zustand in eine am Stift eingeformte Nut greift. Durch Aufstecken des am Filtereinsatz angeordneten Hülsenelementes wird in Folge des Eindrückens der Ausformung der am freien Ende des Federstreifens angeformte Hakenbereich zur Entriegelung angehoben, so dass der Stift gegen die Wirkung der Feder einfahren kann.According to a particularly advantageous embodiment of the invention, in this case also the locking element can be configured as a leaf spring element, which is fixed as a spring strip on the pin member rocker-like. According to the second variant, a spring-loaded metal pin is mounted in a plastic guide. This pin moves when removing the insert filter in the front end position and a plate spring, which is connected to the plastic guide, snaps into a shoulder of the pin and locks it. The access panel can not be closed anymore. By inserting the filter insert, the sheet metal spring is bent, thereby releasing the travel path for the pin again. This is the Lock element, which is designed as a spring strip, attached to the pin member like a rocker. According to a particularly advantageous embodiment of the invention, the spring strip in its central extension region on an outwardly facing formation, which forms a kind of knob guide. The spring strip has at its free end a pointing to the sliding pin hook area, which engages in the locked state in a groove formed on the pin. By attaching the sleeve element arranged on the filter element, the hook region formed on the free end of the spring strip is lifted for unlocking as a result of the depression of the shape, so that the pin can retract against the action of the spring.

Die Figur 1 zeigt in der geschnittenen Seitenansicht einen Wäschetrockner 1 mit einer in einem Gehäuse 2 drehbar gelagerten Trommel 3. Das Gehäuse 2 verfügt hierbei über eine Tür 4, welche eine Beschickungsöffnung 5 verschließt. In dem Gehäuse 2 befindet sich eine Heizeinrichtung 6, welche als Wärmepumpe ausgestaltet sein kann, wobei hierbei die Heizeinrichtung 6 einen Prozessluftstrom mit einem Gebläse erzeugt, der über einen Wärmetauscher 7 strömt, dem ein von außen über eine in der Frontwand 8 des Gehäuses 2 angeordnete Revisionsklappe 9 zugänglicher Filtereinsatz 10 im Strömungskanal 11 vorgeschaltet ist. Der herausnehmbare Filtereinsatz 10 im Strömungskanal 11 ist insbesondere in den Figuren 2 und 3 zu erkennen, wo im Frontbereich des Gehäuses 2 die Revisionsklappe 9 jeweils im geöffneten Zustand gezeigt wird, wobei in der Figur 2 sich der Filtereinsatz 10 im eingesetzten Zustand und in der Figur 3 im herausgenommenen Zustand befindet.The FIG. 1 shows in the sectional side view of a clothes dryer 1 with a rotatably mounted in a housing 2 Drum 3. The housing 2 in this case has a door 4, which closes a feed opening 5. In the housing 2 is a Heating device 6, which may be configured as a heat pump, in which case the heater 6 generates a process air flow with a fan which flows through a heat exchanger 7, the one accessible from outside via a arranged in the front wall 8 of the housing 2 access door 9 filter insert 10 in the flow channel 11 is connected upstream. The removable filter insert 10 in the flow channel 11 is in particular in the Figures 2 and 3 to recognize where in the front region of the housing 2, the access door 9 is shown in each case in the open state, wherein in the FIG. 2 the filter cartridge 10 in the inserted state and in the FIG. 3 in the removed state.

Wie insbesondere aus der Figur 3 zu erkennen ist, weist zum formschlüssigen Einsatz in den Strömungskanal 11 der Filtereinsatz 10 Hülsenelemente 12 auf, die auf im Strömungskanal 11 angeordnete Zapfenelemente 13 im eingesetzten Zustand steckbar sind und wobei zur korrekten Montage des Filtereinsatzes 10 im Strömungskanal 11 ein Überwachungselement 14, wie dies in den Figuren 4, 5, 6 beziehungsweise 7, 8, 9 gezeigt wird, vorgesehen ist. Dabei ist als Überwachungselement 14 zur korrekten Montage wenigstens einer der Zapfenelemente 13 als Sperrmittel ausgebildet, wie dies in den Figuren 4 und 7 zu erkennen ist. Das Zapfenelement 13 unterbindet bei fehlendem Filtereinsatz 10 im Strömungskanal 11 ein Verschließen der Revisionsklappe 9. Wie insbesondere in der Figur 4 und 5 zu erkennen ist, besteht das Sperrmittel aus einem am Zapfenelement 13 angeordneten teleskopierbarem Stift 15. Der Stift 15 ist gegen die Wirkung einer Feder 16 verschiebbar im Zapfenelement 13 angeordnet. Dabei wirkt der Stift 15 mit einem Riegelelement 17 zusammen, wobei das Riegelelement 17 den Stift 15 im teleskopiertem Zustand, wie dies in der Figur 4 dargestellt ist, sperrt.As in particular from the FIG. 3 can be seen, has for positive engagement in the flow channel 11 of the filter element 10 sleeve members 12 which are plugged into arranged in the flow channel 11 pin elements 13 in the inserted state and wherein for the correct mounting of the filter cartridge 10 in the flow channel 11, a monitoring element 14, as shown in FIG the FIGS. 4 . 5 . 6 7, 8, 9 is provided. It is designed as a monitoring element 14 for the correct installation of at least one of the pin members 13 as a blocking means, as shown in the FIGS. 4 and 7 can be seen. The pin member 13 prevents in the absence of filter insert 10 in the flow channel 11, a closure of the access door 9. As in particular in the FIG. 4 and 5 can be seen, the blocking means consists of a pin member 13 arranged on the telescoping pin 15. The pin 15 is slidably disposed against the action of a spring 16 in the pin member 13. In this case, the pin 15 cooperates with a locking element 17, wherein the locking element 17, the pin 15 in the telescoped state, as shown in the FIG. 4 is shown, locks.

Durch Aufstecken des am Filtereinsatz 10 angeordneten Hülsenelementes 12 wird das Riegelelement 17 entriegelt, wie dies insbesondere in der Figur 5 gezeigt wird, wo insbesondere das Hülsenelement 12 über das Riegelelement 17 verschoben dargestellt ist. Das Riegelelement 17 umfasst hierbei ein quer zur Verschieberichtung des Stiftes 15 beweglich angeordnetes Nockenelement. Der Öffnungsrand 18 des Hülsenelementes 12 drückt hierbei das Nockenelement gegen die Schwerkraft nach innen, so dass die freie Beweglichkeit des Stiftes 15 erzielt wird. Das Nockenelement ist hierbei in einem Zapfenbereich verschieblich gelagert. Wie insbesondere aus der Zusammenschau der Figur 4, 5, und 6 zu erkennen ist, ist das Nockenelement gegen die Wirkung der Schwerkraft in die entriegelnde Lage bringbar, wie dies in der Figur 5 und 6 gezeigt wird. Die Figur 6 zeigt dann den eingeschobenen Stift 15, wobei dann die Revisionsklappe 9 im Öffnungsbereich des Gehäuses 2 beziehungsweise in der Frontwand 8 zu liegen kommt.By attaching the filter element 10 arranged on the sleeve member 12, the locking element 17 is unlocked, as in particular in the FIG. 5 is shown where in particular the sleeve member 12 is shown displaced over the locking element 17. The locking element 17 in this case comprises a transversely to the direction of displacement of the pin 15 movably arranged cam member. The opening edge 18 of the sleeve member 12 in this case pushes the cam member against gravity to the inside, so that the free mobility of the pin 15 is achieved. The cam element is in this case mounted displaceably in a pin area. As in particular from the synopsis of FIG. 4 . 5 , and 6 can be seen, the cam member against the action of gravity in the unlocking position can be brought, as shown in the FIG. 5 and 6 will be shown. The FIG. 6 then shows the inserted pin 15, in which case the inspection flap 9 comes to rest in the opening region of the housing 2 or in the front wall 8.

Eine weitere Variante des erfindungsgemäßen Überwachungselementes 14 ist in den Figuren 7, 8 und 9 gezeigt, wobei hierbei das Überwachungselement 14 ein Blattfederelement 19 umfasst, welches als Federstreifen 20 am Zapfenelement 13 wippenartig angeordnet ist. Der Federstreifen 20 weist hierbei in seinem mittleren Erstreckungsbereich eine nach außen weisende Ausformung 21 auf, die etwa dem Nockenelement gemäß der ersten Variante entspricht. An seinem freien Ende weist hierbei der Federstreifen 20 einen zum verschiebbaren Stift 15 weisenden Hakenbereich 22 auf, der im verriegeltem Zustand, dargestellt in der Figur 7, in einer am Stift 15 eingeformte Nut 23 greift. Somit ist der Stift 15 in dieser Situation für ein Einschieben gesperrt, so dass die Revisionsklappe 9 nicht geschlossen werden kann.Another variant of the monitoring element 14 according to the invention is in the FIGS. 7 . 8th and 9 shown, in which case the monitoring element 14 comprises a leaf spring element 19, which is arranged as a spring strip 20 on the pin member 13 rocker-like. In this case, the spring strip 20 has, in its middle extent region, an outward-pointing formation 21 which corresponds approximately to the cam element according to the first variant. At its free end, in this case the spring strip 20 has a hook portion 22 facing the displaceable pin 15, which in the locked state, shown in FIG FIG. 7 , engages in a groove 15 formed on the pin 23. Thus, the pin 15 is locked in this situation for insertion, so that the access door 9 can not be closed.

Wird nun wie in der Figur 8 dargestellt, das Hülsenelement 12 mit seinem Öffnungsrand 18 über die Ausformung 21 geschoben, so wird die als Nocken ausgebildete Ausformung 21 nach innen gedrückt, so dass über die Nase 24 eine Wippbewegung hervorgehoben wird, die insbesondere den zum Stift 15 weisenden Hakenbereich 22 anhebt, so dass der Hakenbereich 22 aus der Nut 23 am Stift 15 herausgehoben wird, und dadurch die Entriegelung vorgenommen wird. Der Stift 15 wird dann eingefahren, sowie dies in der Figur 9 dargestellt ist, wobei sich dann auch die Revisionsklappe 9 schließen lässt.Will now be like in the FIG. 8 shown, the sleeve member 12 is pushed with its opening edge 18 on the formation 21, the formed as a cam molding 21 is pressed inward, so that a luffing motion is emphasized on the nose 24, which in particular raises the pin 15 pointing hook area 22, so that the hook portion 22 is lifted out of the groove 23 on the pin 15, and thereby the unlocking is made. The pin 15 is then retracted, as well as in the FIG. 9 is shown, which can then close the access door 9.
