Description

Die Erfindung betrifft einen Haushaltswäschetrockner umfassend eine Reinigungsvorrichtung für ein innerhalb eines Prozessluft-Kreislaufes des Haushaltswäschetrockners angeordnetes Bauteil der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a household laundry dryer comprising a cleaning device for a arranged within a process air cycle of household laundry dryer component specified in the preamble of claim 1. Art.

Eine derartige Reinigungsvorrichtung ist beispielsweise aus der EP 0 468 573 A1 als bekannt zu entnehmen, bei der ein als Arbeitsmittelverdampfer ausgestalteter Wärmetauscher mittels einer als Flachbürste ausgestalteten Reinigungsbürste von Flusen oder dergleichen Schmutz zu befreien ist, welche entlang einer Stirnseite des Verdampfers zu bewegen ist. Hierdurch ist es möglich, die trotz des Vorsehens eines Flusensiebs innerhalb des Prozessluft-Kreislaufes bis zu dem Verdampfer gelangten und dort durch das Kondensieren der feuchtwarmen Prozessluft abgelagerten Flusen oder dergleichen Schmutz - zumindest über eine gewisse Tiefe - zu entfernen. Die Reinigungsbürste wird dabei mittels einer Antriebsstange entlang der Stirnseite des Verdampfers bewegt, welche an ihrem gegenüberliegenden Ende an einer Kurbel eines Antriebsmechanismus gelagert ist.Such a cleaning device is for example from the EP 0 468 573 A1 to be known, in which a designed as a working medium evaporator heat exchanger is freed by means of a designed as a flat brush cleaning brush of lint or the like dirt, which is to move along an end face of the evaporator. This makes it possible, despite the provision of a lint filter within the process air cycle reached the evaporator and there deposited by the condensation of the moist heat process air lint or the like dirt - at least over a certain depth - to remove. The cleaning brush is moved by means of a drive rod along the end face of the evaporator, which is mounted at its opposite end to a crank of a drive mechanism.

Aufgabe der vorliegenden Erfindung ist es, eine Reinigungsvorrichtung der eingangs genannten Art so zu verbessern, dass eine hohe Betriebssicherheit insbesondere des Antriebsmechanismus für die Reinigungsbürste gegeben ist.Object of the present invention is to improve a cleaning device of the type mentioned so that a high reliability, in particular of the drive mechanism for the cleaning brush is given.

Diese Aufgabe wird erfindungsgemäß durch einen Haushaltswäschetrockner umfassend eine Reinigungsvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung ergeben sich aus den abhängigen Patentansprüchen.This object is achieved by a household laundry dryer comprising a cleaning device with the features of claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention will become apparent from the dependent claims.

Bei der Reinigungsvorrichtung nach der Erfindung ist die Antriebsstange der Reinigungsbürste entlang einer Führung des Antriebsmechanismus zu verfahren, der über wenigstens zwei flexible Dichtungselemente gegen Flusen oder dergleichen Schmutz geschützt ist, zwischen welchen die Antriebsstange hindurchgeführt und entlang der Führung des Antriebsmechanismus zu verfahren ist. Mit anderen Worten ist es also erfindungsgemäß vorgesehen, den Antriebsmechanismus über eine Dichtungsanordnung mit wenigstens zwei flexiblen Dichtungselementen so zu schützen, dass zwar einerseits die Antriebsstange entlang ihrer Führung verfahren werden kann, dass jedoch andererseits ein sicherer Schutz des Antriebsmechanismus gegen Flusen oder dergleichen Schmutz gewährleistet ist. Hierzu sind die beiden flexiblen Dichtungselemente im Überdeckungsbereich mit der Führung für die Antriebsstande entweder einander überlappend oder stumpf aneinander stoßend ausgebildet. In jedem Fall sind jedoch die beiden Dichtungselemente so bemessen und zueinander angeordnet, dass der Antriebsmechanismus sowie dessen Führung für die Antriebsstange besonders gut gegen Verunreinigungen durch Flusen oder dergleichen geschützt sind.In the cleaning device according to the invention, the drive rod of the cleaning brush is to be moved along a guide of the drive mechanism, which is protected by at least two flexible sealing elements against lint or the like dirt, between which the drive rod is guided and to move along the guide of the drive mechanism. In other words it is According to the invention provided to protect the drive mechanism via a seal assembly with at least two flexible sealing elements so that on the one hand the drive rod can be moved along its guide, but on the other hand, a reliable protection of the drive mechanism against lint or the like dirt is guaranteed. For this purpose, the two flexible sealing elements in the covering area with the guide for the drive levels are either overlapping or butt-end abutting each other. In any case, however, the two sealing elements are so dimensioned and arranged to each other that the drive mechanism and its guide for the drive rod are particularly well protected against contamination by lint or the like.

Die überlappende Anordnung der flexiblen Dichtungselemente im Bereich der Hindurchführung der Antriebsstange hat sich dabei als besonders geeignet erwiesen, um - mit einer Art Labyrinthdichtung - das Eindringen von Flusen oder dergleichen Schmutz in den Antriebsmechanismus zuverlässig zu vermeiden. Dabei kann ein Durchtritt von Flusen oder dergleichen Schmutzpartikel zwischen den beiden flexiblen Dichtungselementen hindurch auf besonders sichere Weise vermieden werden, wenn die Breite der Überlappung zumindest etwa dem Durchmesser der Antriebsstange der Reinigungsbürste entspricht.The overlapping arrangement of the flexible sealing elements in the area of the passage of the drive rod has proved to be particularly suitable to - reliably avoid - with a kind of labyrinth seal - the ingress of lint or the like dirt in the drive mechanism. In this case, a passage of lint or the like dirt particles between the two flexible sealing elements can be avoided in a particularly secure manner, if the width of the overlap corresponds at least approximately to the diameter of the drive rod of the cleaning brush.

In einer alternativen Ausführungsform können die beiden flexiblen Dichtungselemente im Bereich der Hindurchführung der Antriebsstange auch stumpf aneinander stoßen. Hierdurch ergibt sich eine besonders ebene Dichtungsanordnung der flexiblen Dichtungselemente, so dass sich insbesondere im Bereich der Hindurchführung der Antriebsstange keine Flusen oder dergleichen Schmutzpartikel absetzen können.In an alternative embodiment, the two flexible sealing elements in the region of the leadthrough of the drive rod can also butt against one another. This results in a particularly flat sealing arrangement of the flexible sealing elements, so that in particular in the area of the passage of the drive rod no lint or the like dirt particles can settle.

In einer - einem der beiden äußeren Enden der Führung entsprechenden - Ruhestellung der Reinigungsbürste ist vorteilhafter Weise eine Durchgangsöffnung innerhalb der Dichtungselemente eingebracht, durch welche die Antriebsstange in der Ruhestellung hindurchgeführt ist. Mit anderen Worten sind die beiden Dichtungselemente in der Ruhestellung der Reinigungsbürste im Bereich der Antriebsachse freigeschnitten, damit die Dichtungselemente in dieser Position glatt anliegen und sich nicht bleibend verformen können.In a - corresponding to one of the two outer ends of the guide - rest position of the cleaning brush is advantageously a through hole introduced within the sealing elements, through which the drive rod is passed in the rest position. In other words, the two sealing elements are cut free in the rest position of the cleaning brush in the drive axle, so that the sealing elements lie smoothly in this position and can not deform permanently.

In weiterer Ausgestaltung der Erfindung ist eine Steuereinrichtung vorgesehen, über welche der Prozessluft-Kreislauf des Haushaltswäschetrockners während der Reinigung des Bauteils abzuschalten ist. Mit anderen Worten soll das Bauteil vorzugsweise nur dann gereinigt werden, wenn die Prozessluft abgeschaltet ist und demgemäß in der Reinigungsphase auch keine Flusen oder dergleichen Schmutz gefördert werden. Hierdurch ist sichergestellt, dass möglichst wenige Flusen oder dergleichen Schmutzpartikel mit dem Antriebsmechanismus der Reinigungsvorrichtung in Kontakt kommen können.In a further embodiment of the invention, a control device is provided, via which the process air cycle of the household tumble dryer is to be switched off during the cleaning of the component. In other words, the component should preferably be cleaned only when the process air is switched off and accordingly no lint or the like dirt are conveyed in the cleaning phase. This ensures that as few lint or the like dirt particles can come into contact with the drive mechanism of the cleaning device.

Schließlich hat es sich als vorteilhaft gezeigt, die Rundbürste mittels der Führung in einer translatorischen Bewegung zu verfahren. In einer derartigen Anordnung lassen sich die beiden flexiblen Dichtungselemente besonders einfach herstellen und so zueinander anordnen, dass keine Flusen oder dergleichen Schmutzpartikel durch die gebildete Dichtungsanordnung in den Bereich des Antriebsmechanismus gelangen können.Finally, it has proven to be advantageous to move the round brush by means of the guide in a translatory movement. In such an arrangement, the two flexible sealing elements can be particularly easily produced and arranged to each other so that no lint or the like dirt particles can pass through the seal assembly formed in the region of the drive mechanism.

In Figur 1 ist in schematischer Seitenansicht ausschnittsweise ein Kanal 10 eines in einer Strömungsrichtung 12 betriebenen Prozessluft-Kreislaufes eines Haushaltswäschetrockners dargestellt, innerhalb welchem eine Wärmetauscheranordnung 14 mit einem Arbeitsmittelverdampfer 16 und einem Arbeitsmittelverflüssiger 18 angeordnet sind. Hierzu ist der Kanal 10 aufgeschnitten dargestellt. Die aus einer nicht dargestellten Wäschetrommel austretende feuchtwarme Prozessluft des Haushaltswäschetrockners durchströmt zunächst ein Flusensieb 20, durch welches ein überwiegender Teil der bei Durchströmen der Wäschetrommel mitgenommenen Flusen oder dergleichen Schmutzpartikel abgeschieden werden können. Nach dem Durchströmen des Flusensiebs 20 gelangt die feuchtwarme Prozessluft zu dem Arbeitsmittelverdampfer 16, wo sie entsprechend abgekühlt und durch Kondensation getrocknet wird. Das hierbei im Bereich des Arbeitsmittel-Verdampfers 16 entstehende Kondensat strömt über eine Auslassöffnung 22 zu einer Auslassleitung 24, von wo aus es mittels einer nicht dargestellten Pumpe als Brauchwasser abgepumpt wird. Im Überdeckungsbereich mit der Auslassöffnung 22 ist eine Aufnahmeschale 26 vorgesehen, in welcher sich innerhalb des Kondensats befindende Flusen oder dergleichen Schmutzpartikel abscheiden lassen. Die Aufnahmeschale 26 ist demgemäß von Zeit zu Zeit zu entnehmen und zu reinigen. Die über den Arbeitsmittelverdampfer 16 abgekühlte und getrocknete Prozessluft gelangt anschließend zum Arbeitsmittelverflüssiger 18, wo sie erneut aufgeheizt und mittels eines nicht dargestellten Gebläses wieder zur Wäschetrommel hin gefördert wird.In FIG. 1 is a schematic side view of a detail of a channel 10 of a operated in a flow direction 12 process air circuit of a household laundry dryer, within which a heat exchanger assembly 14 with a working medium evaporator 16 and a Arbeitsmittelverflüssiger 18 are arranged. For this purpose, the channel 10 is shown cut open. The moist-warm process air of the household laundry drier exiting from a laundry drum, not shown, first flows through a lint filter 20, by means of which a predominant part of the lint that is entrained when the laundry drum flows through or similar dirt particles can be deposited. After flowing through the lint filter 20, the moist, warm process air reaches the working medium evaporator 16, where it is correspondingly cooled and dried by condensation. The condensate which in this case arises in the region of the working medium evaporator 16 flows via an outlet opening 22 to an outlet line 24, from where it is pumped off as process water by means of a pump (not shown). In the overlap area with the outlet opening 22, a receiving tray 26 is provided, in which can be deposited within the condensate lint or the like dirt particles. The receiving tray 26 is accordingly to be removed and cleaned from time to time. The cooled and dried over the working medium evaporator 16 process air then passes to the working fluid condenser 18, where it is heated again and conveyed back to the laundry drum by means of a blower, not shown.

Da trotz des Flusensiebs 20 ein gewisser Anteil von Flusen oder dergleichen Schmutz bis zu dem Arbeitsmittelverdampfer 16 gelangt, wo sich diese mit dem Kondensat absetzen und die Kühlleistung des Wärmetauschers negativ beeinflussen würden, ist in Strömungsrichtung 12 des Prozessluft-Kreislaufes vor dem Arbeitsmittelverdampfer 16 eine Reinigungsvorrichtung vorgesehen, welche insbesondere in Zusammenschau mit Figur 2 näher erkennbar ist. Hierzu zeigt Figur 2 in schematischer und ausschnittsweiser Draufsicht eine über eine Antriebsstange 28 eines Antriebsmechanismus 30 drehangetriebene Reinigungsbürste 32, welche - wie aus Figur 1 erkennbar - zwischen einer oberen und einer unteren Endposition zumindest annähernd entlang der gesamten vorderen Stirnseite 34 des Arbeitsmittel-Verdampfers 16 gemäß dem Pfeil 36 in vertikaler Richtung zu verfahren ist. Hierzu umfasst der Antriebsmechanismus jeweils beidseitig des Kanals 10 in vertikaler Richtung verlaufende Führungen 38, über welche die Antriebsstange 28 mit ihren beiden Enden geführt ist. Eine der beiden Führungen 38 umfasst eine in Figur 2 erkennbare Zahnstange 40, in welcher ein Zahnrad 42 des Antriebsmechanismus 30 kämmt. Das Zahnrad 42 ist von einem Motor 42 mit Vorgelege antreibbar, welcher ebenfalls am Ende der Antriebsstange 28 angeordnet ist. Durch das Vorgelege ist es möglich, sowohl die Rundbürste 32 als auch das Zahnrad 42 über den gemeinsamen Motor 44 zu betreiben. Mit anderen Worten sorgt der Motor 42 sowohl für die Rotationsbewegung der Reinigungsbürste 32 als auch für deren translatorische Bewegung entlang der vorderen Stirnseite 34 des Arbeitsmittel-Verdampfers 16 bzw. entlang der Führungen 38. Damit die vordere Stirnseite 34 des Arbeitsmittel-Verdampfers 16 zumindest annähernd vollständig von Flusen oder dergleichen Schmutz gereinigt werden kann, sind oberseitig und unterseitig des Kanals 10 Ausbauchungen 46 eingebracht, in welche die Rundbürste 32 eintauchen kann.Since despite the lint filter 20 a certain amount of lint or the like dirt reaches the working medium evaporator 16, where they settle with the condensate and would adversely affect the cooling capacity of the heat exchanger, in the flow direction 12 of the process air circuit before the working medium evaporator 16 is a cleaning device provided, which in particular in conjunction with FIG. 2 is more clearly recognizable. This shows FIG. 2 in a schematic and fragmentary plan view of a drive rod 28 of a drive mechanism 30 rotationally driven cleaning brush 32, which - as from FIG. 1 recognizable - is to be moved in the vertical direction at least approximately along the entire front end face 34 of the working medium evaporator 16 according to the arrow 36 between an upper and a lower end position. For this purpose, the drive mechanism comprises in each case on both sides of the channel 10 in the vertical direction extending guides 38, via which the drive rod 28 is guided with its two ends. One of the two guides 38 comprises an in FIG. 2 recognizable rack 40 in which a gear 42 of the drive mechanism 30 meshes. The gear 42 is driven by a motor 42 with countershaft, which is also arranged at the end of the drive rod 28. By the countershaft, it is possible to operate both the round brush 32 and the gear 42 via the common motor 44. In other words, the motor 42 ensures both the rotational movement of the cleaning brush 32 as well as their translational movement along the front end face 34 of the working medium evaporator 16 and along the guides 38. Thus, the front end face 34 of the working medium evaporator 16 at least approximately completely can be cleaned of lint or the like dirt, bulges 46 are introduced on top and bottom of the channel 10, in which the round brush 32 can dip.

Aus Figur 2 ist erkennbar, dass die Rundbürste 32 mit ihren Borsten, Lappen oder dergleichen in einer gewissen Tiefe von der Stirnseite 34 her in den Arbeitsmittelverdampfer 16 eintauchen kann. Vorzugsweise kann die Rundbürste 32 zumindest bis an ein Arbeitsmittelrohr 50 in den Arbeitsmittelverdampfer 16 eintauchen, da sich erfahrungsgemäß im Bereich der Arbeitsmittel-Rohre 50 sehr viel Kondensat und demgemäß auch Flusen oder dergleichen Schmutzpartikel absetzen.Out FIG. 2 It can be seen that the round brush 32 with its bristles, cloths or the like can dive into the working medium evaporator 16 at a certain depth from the end face 34 forth. Preferably, the round brush 32 can dip into the working medium evaporator 16 at least as far as a working medium pipe 50, since, according to experience, very much condensate and accordingly lint or the like dirt particles settle in the area of the working medium pipes 50.

Damit keine Flusen oder dergleichen Schmutzpartikel in den Bereich des innerhalb eines - entlang einer der Führungen 38 verlaufenden - Aufnahmegehäuses 52 des Aufnahmemechanismus 30 gelangen können, ist dieser über eine insbesondere in den Figuren 3a und 3b noch näher erläuterte Dichtungsanordnung 54 abgedeckt. Hierzu zeigen die Figuren 3a und 3b jeweils in schematischer Draufsicht die Dichtungsanordnung 54 entlang der Linie III - III in Figur 2. Darüber hinaus ist rechts in den Figuren 3a und 3b jeweils eine Schnittansicht durch die Dichtungsanordnung 54 beziehungsweise durch die Antriebsstange 28 - entlang der Schnittlinien in den linken Darstellungen der Dichtungsanordnung 54 - gezeigt. Es ist erkennbar, dass die Dichtungsanordnung 54 im Wesentlichen zwei flexible Dichtungselemente 56, 58 umfasst, welche im vorliegenden Ausführungsbeispiel aus zwei Folienstreifen aus flexiblem Kunststoff bestehen. Die beiden Dichtungselemente 56, 58 sind dabei als jeweils ebene Streifen im Bereich einer Hindurchführung 60 (Figur 2) der Antriebsstange 28 überlappend ausgebildet. Dabei liegen die beiden Dichtungselemente 56, 58 vorzugsweise plan und eben aufeinander. Die Breite der Überlappung der flexiblen Dichtungselemente 56, 58 entspricht dabei dem Durchmesser der Antriebsstange 28. Natürlich wäre es in diesem Zusammenhang auch denkbar, andere Überlappungsbreiten vorzusehen. Wie aus Figur 2 erkennbar ist, sind die beiden Dichtungselemente 54, 55 mit ihren der Hindurchführung 60 abgewandten Längsenden 62 an der Wand des Kanals 10 befestigt. Es ist klar, dass die Überlappung zwischen den beiden Dichtungselementen 56, 58 zumindest annähernd parallel bzw. in Überdeckung mit den Führungen 38 der Antriebsstange 28 bzw. der Reinigungsbürste 32 verlaufen sollte. Außerdem ist klar, dass die Länge der flexiblen Dichtungselemente 56, 58 so bemessen ist, dass die Reinigungsbürste 32 zumindest annähernd vollständig entlang der Stirnseite 34 des Arbeitsmittel- Verdampfers 16 zu verfahren ist. Demgemäß müssen im vorliegenden Ausführungsbeispiel die beiden Dichtungselemente 56, 58 zumindest etwa so lang sein wie die vertikal verlaufenden Führungen 38 am vorderen und hinteren Ende der Reinigungsbürste 32.So that no lint or similar dirt particles can reach into the region of the receiving housing 52 of the receiving mechanism 30 which extends along one of the guides 38, this is provided by means of a particularly in the FIGS. 3a and 3b covered in more detail seal assembly 54 covered. To show the FIGS. 3a and 3b each in a schematic plan view of the seal assembly 54 along the line III - III in FIG. 2 , In addition, right in the FIGS. 3a and 3b each a sectional view through the seal assembly 54 and through the Drive rod 28 - along the lines of intersection in the left representations of the seal assembly 54 - shown. It can be seen that the sealing arrangement 54 essentially comprises two flexible sealing elements 56, 58, which in the present exemplary embodiment consist of two film strips of flexible plastic. The two sealing elements 56, 58 are in each case as flat strips in the region of a passage 60 (FIG. FIG. 2 ) of the drive rod 28 formed overlapping. In this case, the two sealing elements 56, 58 are preferably flat and flat. The width of the overlap of the flexible sealing elements 56, 58 corresponds to the diameter of the drive rod 28. Of course, it would also be conceivable in this context to provide other overlapping widths. How out FIG. 2 can be seen, the two sealing elements 54, 55 are fixed with their passage 60 facing away from the longitudinal ends 62 on the wall of the channel 10. It is clear that the overlap between the two sealing elements 56, 58 should extend at least approximately parallel or in register with the guides 38 of the drive rod 28 or the cleaning brush 32. In addition, it is clear that the length of the flexible sealing elements 56, 58 is dimensioned such that the cleaning brush 32 is at least approximately complete along the end face 34 of the working medium evaporator 16. Accordingly, in the present embodiment, the two seal members 56, 58 must be at least about as long as the vertically extending guides 38 at the front and rear ends of the cleaning brush 32.

In Figur 3b ist erkennbar, dass in einer Ruhestellung der Rundbürste 32 innerhalb der beiden Dichtungselemente 56, 58 - im Bereich der Hindurchführung der Antriebsstange 28 - eine Durchgangsöffnung vorgesehen ist, damit die Dichtungselemente 56, 58 in dieser Ruheposition der Reinigungsbürste 32 glatt aneinander anliegen und sich nicht bleibend verformen können. Mit anderen Worten ist von den mittleren Längsenden 64 der beiden Dichtungselemente 56, 58 her jeweils eine etwa halbkreisförmige Ausnehmung eingebracht, die sich im Überlappungsbereich bzw. im Bereich der Hindurchführung 60 der Antriebsstange 28 zu einer kreisrunden Durchgangsöffnung 66 ergänzen, durch welche die Antriebsstange 28 hindurchgeführt ist. Da die Reinigungsbürste 32 vorzugsweise ihre Ruhestellung in einer oberen oder unteren Endposition innerhalb der Ausbauchungen 46 (Figur 1) einnimmt, ist die Durchgangsöffnung 66 vorzugsweise am oberen oder unteren Ende der Dichtungsanordnung 54 vorgesehen. Die Reinigungsvorrichtung ist hier mit einer nicht dargestellten Steuerungseinrichtung verbunden, über welche der Prozessluft-Kreislauf des Haushaltswäschetrockners während der Reinigung des Arbeitsmittel-Verdampfers 16 abgeschaltet wird bzw. bleibt. Hierdurch soll vermieden werden, dass in der Reinigungsphase des Arbeitsmittel-Verdampfers 16 Flusen oder dergleichen Schmutz über die Prozessluft gefördert werden.In FIG. 3b It can be seen that in a rest position of the round brush 32 within the two sealing elements 56, 58 - in the region of the passage of the drive rod 28 - a through hole is provided so that the sealing elements 56, 58 in this rest position of the cleaning brush 32 smoothly abut each other and not lasting can deform. In other words, each of the central longitudinal ends 64 of the two sealing elements 56, 58 introduced an approximately semicircular recess, which complement each other in the overlap region or in the region of the passage 60 of the drive rod 28 to a circular passage opening 66 through which the drive rod 28 passed is. Since the cleaning brush 32 preferably has its rest position in an upper or lower end position within the bulges 46 (FIG. FIG. 1 ), the through hole 66 is preferably provided at the upper or lower end of the seal assembly 54. The cleaning device is here with a control device, not shown connected, via which the process air circuit of the household laundry dryer is turned off during cleaning of the working medium evaporator 16 or remains. In this way, it is to be avoided that in the cleaning phase of the working medium evaporator 16 lint or the like dirt are conveyed via the process air.

Wird nun die Reinigungsbürste 32 - gemäß dem Pfeil 36 (Figur 1) - entlang der Stirnseite 34 des Arbeitsmittel-Verdampfers 16 verfahren, so verformt sich die Dichtungsanordnung 54 durch die in Figur 3a dargestellte Weise. Mit anderen Worten wird die Antriebsstange 28 aus der Durchgangsöffnung 66 (Figur 3b) herausbewegt, wodurch sich die beiden mittleren Längsenden 64 der Dichtungselemente 56, 58 - unter Anschmiegung an die Antriebsstange 28 - entsprechend verformen. Dabei wird die Antriebsstange 28 längs der Überlappung bzw. längs der Führungen 38 (Figur 1) derart bewegt, dass beide Dichtungselemente 56, 58 die Antriebsstange 28 - zumindest weitestgehend - dicht umschließen. Wird demgemäß mit der Reinigungsbürste 32 eine translatorische Bewegung zur Reinigung des Arbeitsmittel-Verdampfers 16 durchgeführt, so drückt die Antriebsstange 28 die beiden Dichtungselemente 56, 58 im Bereich von deren jeweiligem mittleren Längsende 64 auseinander. Da die Reinigung des Arbeitsmittel-Verdampfers 16 relativ schnell abgeschlossen ist, ist auch keine plastische Verformung der beiden Dichtungselemente 56, 58 durch das Auseinanderdrücken zu befürchten. Die mittleren Längsenden 64 wölben sich dabei - wie aus der Schnittansicht in Figuren 3a erkennbar - im Bereich der Hindurchführung 60 vorzugsweise nach oben hin, so dass auch kein Kondensat oder dergleichen in den Antriebsmechanismus 30 gelangen kann.If now the cleaning brush 32 - according to the arrow 36 ( FIG. 1 ) - moved along the end face 34 of the working medium evaporator 16, so deforms the seal assembly 54 through the in FIG. 3a illustrated way. In other words, the drive rod 28 is removed from the through opening 66 (FIG. FIG. 3b ), whereby the two middle longitudinal ends 64 of the sealing elements 56, 58 - deformed - in accordance with the drive rod 28 - accordingly. In this case, the drive rod 28 along the overlap or along the guides 38 (FIG. FIG. 1 ) such that both sealing elements 56, 58, the drive rod 28 - at least largely - tightly enclose. Accordingly, if a translational movement is carried out with the cleaning brush 32 for cleaning the working medium evaporator 16, then the drive rod 28 forces the two sealing elements 56, 58 apart in the region of their respective central longitudinal end 64. Since the cleaning of the working medium evaporator 16 is completed relatively quickly, no plastic deformation of the two sealing elements 56, 58 is to be feared by the pressing apart. The middle longitudinal ends 64 bulge here - as from the sectional view in FIGS. 3a recognizable - in the region of the passageway 60 preferably upwards, so that no condensate or the like can get into the drive mechanism 30.
