Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft eine Wäschebehandlungsvorrichtung, insbesondere einen Wäschetrockner oder Wäschebehandlungsschrank, mit einem Wäscheaufnahmeraum zur Aufnahme von Wäsche und einem Luftaufbereitungssystem zum Aufbereiten der Prozessluft sowie einem Ventilator zum Fördern von Prozessluft aus dem Wäscheaufnahmeraum in das Luftaufbereitungssystem und zurück. Weiter besitzt das Gerät ein im Luftaufbereitungssystem angeordnetes erstes Filter und eine Steuerung zum Steuern der Wäschebehandlungsvorrichtung.The invention relates to a laundry treatment device, in particular a tumble dryer or laundry treatment cabinet, with a laundry receiving space for receiving laundry and an air conditioning system for processing the process air and a fan for conveying process air from the laundry receiving space in the air treatment system and back. Further, the apparatus has a first filter disposed in the air treatment system and a controller for controlling the laundry treating apparatus.

Hintergrundbackground

Geräte dieser Art, wie sie z.B. in EP2492389 und EP2434047 beschreiben sind, bedürfen einer regelmässige Wartung der Filter. Zudem haben die Filter in den Geräten den Nachteil, dass sie den Luftwiderstand im Luftaufbereitungssystem erhöhen. Es wird deshalb nach Massnahmen gesucht, die Filter so auszugestalten, dass sie einfach zu reinigen sind und möglichst geringen Luftwiderstand besitzen.Devices of this kind, such as in EP2492389 and EP2434047 require regular maintenance of the filters. In addition, the filters in the devices have the disadvantage that they increase the air resistance in the air treatment system. It is therefore sought measures to design the filter so that they are easy to clean and have the lowest possible air resistance.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der vorliegenden Erfindung, ein Gerät der Eingangs genannten Art bereitzustellen, bei welchem der Reinigungsaufwand und/oder Luftwiderstand des bzw. der Filter reduziert ist.It is an object of the present invention to provide a device of the type mentioned, in which the cleaning effort and / or air resistance of the filter or is reduced.

Diese Aufgabe wird von der Wäschebehandlungsvorrichtung gemäss Anspruch 1 gelöst. Demgemäss ist eine von der Steuerung steuerbare Umschaltmechanik vorgesehen, mit welcher die Prozessluft wahlweise durch das erste Filter oder am ersten Filter vorbei geführt werden kann.This object is achieved by the laundry treatment device according to claim 1. Accordingly, a controllable by the control switching mechanism is provided, with which the process air can be selectively passed through the first filter or the first filter over.

Damit wird es möglich, programmgesteuert und bedarfsgerecht das Filter zu- oder wegzuschalten. Solange das Filter weggeschaltet, d.h. inaktiv, ist, kann es nicht verschmutzen, und zudem wird der Luftwiderstand verringert.This makes it possible, programmatically and on demand, the filter on or off. As long as the filter is switched off, i. is inactive, can not pollute, and also reduces air resistance.

Damit geht die Erfindung also einen anderen Weg als der Stand der Technik, indem nicht das Filter optimiert wird, sondern das Filter wird nur bei Bedarf eingesetzt.Thus, the invention is a different way than the prior art by not the filter is optimized, but the filter is used only when needed.

In einer bevorzugten Ausführung kann die Umschaltmechanik dazu ausgestaltet sein, mindestens einen Teil des ersten Filters zu bewegen, um es so in den Luftstrom einzuführen oder aus dem Luftstrom zu entfernen.In a preferred embodiment, the switching mechanism may be configured to move at least a portion of the first filter so as to introduce it into the air stream or remove it from the air stream.

In einer anderen bevorzugten Ausführung besitzt die Umschaltmechanik eine bewegliche Klappe, mit welcher der Luftstrom wahlweise um das erste Filter herum umgeleitet oder durch das erste Filter hindurchgeleitet werden kann.In another preferred embodiment, the switching mechanism has a movable flap with which the air flow can optionally be diverted around the first filter or passed through the first filter.

Zusätzlich zum genannten ersten Filter kann ein zweites Filter vorgesehen sein, welches fest im Luftstrom der Prozessluft angeordnet ist. Mit anderen Worten kann dieses zweite Filter also von der Steuerung des Geräts nicht zu- und weggeschaltet werden, sondern es verbleit immer im Luftstrom, so dass es dauernd seine Filterwirkung entfaltet. Dieses zweite Filter dient insbesondere dazu, Flusen aufzufangen, die vom inaktiven ersten Filter nicht erfasst werden.In addition to the first filter mentioned, a second filter may be provided which is fixedly arranged in the air flow of the process air. In other words, this second filter can therefore not be switched on and off by the control of the device, but it always leads in the air stream, so that it constantly has its filtering effect unfolded. This second filter is used in particular to catch lint that is not detected by the inactive first filter.

Die Steuerung kann die Umschaltmechanik abhängig vom Signal eines Sensors, insbesondere eines Feuchtesensors, Temperatursensors oder Flusensensors, steuern. Wie weiter unten beschrieben wird, geben die Signale dieser Sensoren Hinweise darauf, ob das erste Filter benötigt wird.The controller can control the switching mechanism depending on the signal of a sensor, in particular a humidity sensor, temperature sensor or lint sensor. As will be described below, the signals from these sensors indicate whether the first filter is needed.

Die Steuerung kann weiter dazu ausgestaltet sein, aus dem Unterschied der Strömungsgeschwindigkeit der Prozessluft und/oder der Leistungsaufnahme des Ventilators bei zugeschaltetem (aktivem) und nicht zugeschaltetem (inaktivem) ersten Filter den Verschmutzungsgrad des ersten Filters zu detektieren.The controller can be further configured to detect the degree of soiling of the first filter from the difference between the flow rate of the process air and / or the power consumption of the fan when the first filter is activated (active) and not switched on (inactive).

Die vorliegende Erfindung eignet sich insbesondere zu Verwendung in Wäschetrocknern mit sich drehender Trommel, wo die Prozessluft relativ stark mit Flusen befrachtet sein kann. Sie kann jedoch vorteilhaft auch in einem Wäschebehandlungsschrank eingesetzt werden, wo die zu behandelnde Wäsche in der Regel ruhend untergebracht ist.The present invention is particularly suitable for use in tumble dryers where the process air may be relatively heavily loaded with lint. However, it can be advantageously used in a laundry treatment cabinet, where the laundry to be treated is usually housed dormant.

Wege zur Ausführung der ErfindungWays to carry out the invention Übersicht:Overview:

Der in Fig. 1 und 2 dargestellte Wäschetrockner besitzt in bekannter Weise eine drehbare Wäschetrommel 1 als Wäscheaufnahmeraum zur Aufnahme der zu trocknenden Wäsche 2. Die Wäschetrommel 1 kann nach dem Einfüllen der feuchten Wäsche 2 durch eine Tür 3 verschlossen werden. Sodann wird vom Benutzer des Geräts das Trockenprogramm gestartet, z.B. durch Drücken einer Taste an einem Bedienfeld 4 des Wäschetrockners. Eine Steuerung 5 des Wäschetrockners übernimmt dann die Kontrolle über die Schritte des Trockenprogramms.The in Fig. 1 and 2 shown dryer has in a known manner a rotatable laundry drum 1 as a laundry receiving space for receiving the laundry to be dried 2. The laundry drum 1 can be closed by a door 3 after filling the wet laundry 2. The user of the device then starts the drying program, for example by pressing a button on a control panel 4 of the tumble dryer. A controller 5 of the tumble dryer then takes control of the steps of the drying program.

Das Gerät besitzt weiter ein Luftaufbereitungssystem zum Aufbereiten der Prozessluft. Dieses umfasst in bekannter Weise Mittel zum Trocknen und Heizen der Prozessluft. In der dargestellten Ausführung werden diese durch den Verdampfer 6 und den Kondensator 7 einer Wärmepumpe gebildet. Weiter kann eine Zusatzheizung 8 vorgesehen sein. Ein Ventilator 9 dient dazu, die Prozessluft aus der Trommel 1 in das Luftaufbereitungssystem und wieder zurück zu fördern.The device also has an air conditioning system for processing the process air. This includes in a known manner means for drying and heating the process air. In the illustrated embodiment, these are formed by the evaporator 6 and the condenser 7 of a heat pump. Further, an additional heater 8 may be provided. A fan 9 serves to convey the process air from the drum 1 into the air treatment system and back again.

Zum Trocknen der Wäsche 2 wird die Wäschetrommel 1 durch einen Antrieb (nicht gezeigt) in einer oder in wechselnden Richtungen rotiert und die sich in der Wäschetrommel 1 befindende Wäsche 2 aufgelockert und durchmischt. Die Prozessluft wird aus der Trommel 1 in die Türe 3 des Geräts gefördert. Von dort gelangt sie über den unteren Bereich des Türrahmens in einen Luftkanal 10, der sie zum Verdampfer 6 und Kondensator 7 führt. Danach durchläuft die Prozessluft die Zusatzheizung 8 und den Ventilator 9, um wieder in die Trommel 1 zurückzukehren.To dry the laundry 2, the laundry drum 1 is rotated by a drive (not shown) in one or in alternating directions and the laundry 2 located in the laundry drum 1 is loosened up and mixed. The process air is conveyed out of the drum 1 into the door 3 of the device. From there it passes over the lower region of the door frame into an air duct 10 which leads it to the evaporator 6 and condenser 7. Thereafter, the process air passes through the auxiliary heater 8 and the fan 9 to return to the drum 1 again.

Beim Durchgang der Prozessluft durch die Wäschetrommel 1 mit der sich darin befindenden Wäsche 2 wird nicht nur Feuchtigkeit ausgetragen bzw. im Prozessluftstrom mitgeführt, sondern auch sog. Flusen und u.U. auch andere Fremdkörper. Wenn im Folgenden von "Flusen" gesprochen wird, so sind solche "Fremdkörper" explizit eingeschlossen.During the passage of the process air through the laundry drum 1 with the laundry 2 located therein not only moisture is discharged or carried in the process air stream, but also so-called. Fluff and u.U. also other foreign bodies. When the term "lint" is used below, such "foreign bodies" are explicitly included.

Die Flusen sollten vor dem Durchgang der Prozessluft 12 durch die Wärmetauscher des Verdampfers 6 und Kondensators 7 aus der Prozessluft 12 entfernt werden, um Beeinträchtigungen des Wirkungsgrads bzw. sogar Beschädigungen zu vermeiden.The lint should be removed from the process air 12 before the passage of the process air 12 through the heat exchanger of the evaporator 6 and the condenser 7 in order to avoid deterioration of the efficiency or even damage.

Hierzu sind verschiedene Filter im Prozessluftstrom vorgesehen. So kann in der Türe ein Türfilter 20 vorgesehen sein, welches eine erste Filterstufe bildet. Unterhalb des Türrahmens des Geräts kann ein im Folgenden als Rahmenfilter 21 bezeichnetes Filter angeordnet sein. Zwischen dem Rahmenfilter 21 und dem Verdampfer 6 kann zudem ein im Folgenden als "letztes Filter" 22 bezeichnetes Filter vorgesehen sein.For this purpose, various filters are provided in the process air stream. Thus, a door filter 20 may be provided in the door, which forms a first filter stage. Below the door frame of the device, a filter hereinafter referred to as a frame filter 21 is arranged be. Between the frame filter 21 and the evaporator 6 may also be provided hereinafter referred to as "last filter" 22 designated filter.

Erfindungsgemäss ist mindestens einem dieser Filter eine von der Steuerung 5 steuerbare Umschaltmechanik zugeordnet, mit welcher die Prozessluft wahlweise durch das Filter oder am Filter vorbei geführt werden kann. Das Filter, dem die Umschaltmechanik zugeordnet ist, wird im Folgenden als "erstes Filter" bezeichnet, wobei diese Bezeichnung nicht zwingend impliziert, dass es sich um das erste Filter um Luftstrom nach der Trommel 1 handelt.According to the invention, at least one of these filters is assigned a controllable by the controller 5 switching mechanism with which the process air can be optionally passed through the filter or the filter over. The filter to which the switching mechanism is assigned is hereinafter referred to as "first filter", whereby this designation does not necessarily imply that it is the first filter for air flow downstream of the drum 1.

Es können auch mehr als zwei Filter vorgesehen sein, z.B. drei oder vier Filter, von mindestens eines umschaltbar ist. Es können auch mehrere Filter umschaltbar sein, d.h. das Gerät besitzt "mindestens ein" erstes Filter, das umgeschaltet werden kann. Es können auch mehrere stationäre, nicht umschaltbare Filter vorgesehen sein.There may also be more than two filters, e.g. three or four filters, of at least one switchable. Several filters may also be switchable, i. The device has "at least one" first filter that can be switched. It can also be provided several stationary, non-switchable filter.

Filteranordnungen:Filter assemblies:

Im Folgenden werden anhand von Fig. 3 - 10 einige Filteranordnungen zur Realisierung des ersten Filters und der Umschaltvorrichtung beschrieben. Diese Figuren zeigen jeweils einen vertikalen Schnitt durch die Filteranordnung, wobei der Luftstrom mit einem Pfeil dargestellt wird. Die jeweils erste Zeichnung zeigt das Filter in aktivem Zustand, während die jeweils zweite Figur das Filter in inaktivem Zustand darstellt. Das Filter wird jeweils mit der Bezugsziffer 24 gekennzeichnet. In den dargestellten Ausführungen ist es in einem Filterraum angeordnet, der die Bezugsziffer 25 trägt. Die Prozessluft tritt durch eine Eintrittsöffnung 26 in den Filterraum 25 ein und verlässt diesen durch eine Austrittsöffnung 27. Die Umschaltmechanik trägt die Bezugsziffer 29.The following are based on Fig. 3 - 10 some filter arrangements for the realization of the first filter and the switching device will be described. These figures each show a vertical section through the filter assembly, wherein the air flow is represented by an arrow. The first drawing shows the filter in the active state, while the second figure shows the filter in an inactive state. The filter is identified by the reference numeral 24. In the illustrated embodiments, it is arranged in a filter chamber, which carries the reference numeral 25. The process air enters through an inlet opening 26 in the filter chamber 25 and leaves it through an outlet opening 27. The switching mechanism carries the reference numeral 29th

Eine erste Ausgestaltung der Filteranordnung ist in Fig. 3 und 4 illustriert. Bei dieser Ausführung wird das Filter 24 von der Umschaltmechanik 29 bewegt, um es in den Luftstrom einzuführen bzw. aus dem Luftstrom zu entfernen.A first embodiment of the filter arrangement is in 3 and 4 illustrated. In this version the filter 24 is moved by the switching mechanism 29 to introduce it into the air flow or to remove it from the air flow.

Das Filter 24 der Ausführung nach Fig. 3 und 4 besitzt z.B. rechteckigen Querschnitt. Es erstreckt sich in der aktiven Position ungefähr diagonal durch den Filterraum 25 und trennt die Eintrittsöffnung 26 von der Austrittsöffnung 27, während es in seiner inaktiven Position an einer Wand 28 des Filterraums 25 anliegt, so dass es den Pfad von Eintrittsöffnung 26 zu Austrittsöffnung 27 nicht mehr unterbricht. Auf diese Weise kann das Filter zu- bzw. weggeschaltet werden.The filter 24 of the embodiment 3 and 4 has eg rectangular cross-section. It extends in the active position approximately diagonally through the filter chamber 25 and separates the inlet opening 26 from the outlet opening 27, while in its inactive position against a wall 28 of the filter chamber 25, so that it does not the path from the inlet opening 26 to the outlet opening 27 interrupts more. In this way, the filter can be switched on or off.

In der Ausführung nach Fig. 3 und 4 besitzt das erste Filter 24 zwei Seitenkanten 30, 31, welche versteift sind. Die erste Seitenkante 30 ist fest angeordnet, während die zweite Seitenkante mit Hilfe der Umschaltmechanik 29 quer zum Luftstrom bewegbar ist. In der Ausführung nach Fig. 3 und 4 ist die Umschaltmechanik 29 als eine von einem Motor 33 angetriebene Gewindestange 34 dargestellt, wobei dem Fachmann auch alternative Ausführungen bekannt sind.In the execution after 3 and 4 The first filter 24 has two side edges 30, 31 which are stiffened. The first side edge 30 is fixed, while the second side edge by means of the switching mechanism 29 is movable transversely to the air flow. In the execution after 3 and 4 For example, the changeover mechanism 29 is shown as a threaded rod 34 driven by a motor 33, alternative embodiments also being known to those skilled in the art.

In der Ausführung nach Fig. 3 und 4 liegt die zweite, bewegte Seitenkante 31 näher an der Eintrittsöffnung als die erste Seitenkante 30. Dies hat den Vorteil, dass in der in Fig. 4 gezeigten inaktiven Stellung des Filters dessen Eintrittsfläche zur Wand 28 hin orientiert ist, so dass an der Eintrittsfläche anhaftende Flusen vom Luftstrom geschützt sind und nicht fortgetragen werden.In the execution after 3 and 4 the second, moving side edge 31 is closer to the inlet opening than the first side edge 30. This has the advantage that in the in Fig. 4 shown inactive position of the filter whose entrance surface is oriented towards the wall 28, so that adhering to the entrance surface lint be protected from the air flow and are not carried away.

In der zweiten Ausführung nach Fig. 5 und 6 bildet das erste Filter 24 einen Beutel mit einer Eingangsöffnung 35, durch welche die Prozessluft im aktiven Zustand des Filters eintritt. Die Umschaltmechanik 29 ist so ausgestaltet, dass sie den Querschnitt der Eingangsöffnung 35 variiert.In the second execution after FIGS. 5 and 6 The first filter 24 forms a bag with an inlet opening 35 through which the process air enters in the active state of the filter. The switching mechanism 29 is configured to vary the cross section of the input port 35.

In der dargestellten Ausführung ist hierzu wieder eine erste Seitenkante 30 des Filters stationär angeordnet, während die gegenüber liegende zweite Seitenkante 31 mit der Umschaltmechanik 29 auf die erste Seitenkante 30 zu bzw. von dieser weg bewegt werden kann.In the illustrated embodiment, a first side edge 30 of the filter is again arranged stationary for this purpose, while the opposite second side edge 31 can be moved with the switching mechanism 29 on the first side edge 30 to and from this.

Vorzugsweise bildet das Filter 24 einen bis auf die Eingangsöffnung 35 allseitig geschlossenen Beutel. Denkbar ist jedoch auch, dass die parallel zur Zeichenebene von Fig. 5 und 6 verlaufenden Seiten des Beutels nicht von Filtergewebe gebildet werden, sondern offen sind, in welchem Fall der Filterinnenraum auf diesen Seiten von den Wänden des Filterraums 25 begrenzt wird.Preferably, the filter 24 forms a bag closed on all sides except for the inlet opening 35. It is also conceivable that the parallel to the plane of FIGS. 5 and 6 extending sides of the bag are not formed by filter fabric, but are open, in which case the filter interior is limited on these sides of the walls of the filter chamber 25.

Fig. 7 und 8 zeigen eine weitere Ausführung des ersten Filters 24, welche sich besonders zur Anordnung in der Türe 3 des Geräts eignet. In dieser Ausführung ist das Filter in einem steifen Rahmen 38 aufgespannt, der seinerseits zur Reinigung entnehmbar in einer Filterhalterung 39 angeordnet ist. Die Filterhalterung 39 besitzt eingangsseitig ein Gitter 40, durch welches die Prozessluft in der aktiven Stellung des Filters zum Filter 24 gelangt. Die Filterhalterung 39 kann nun als ganzes von der Umschaltmechanik 29 zwischen der aktiven und der inaktiven Stellung hin- und herbewegt werden. In der aktiven Stellung schliesst die Filterhalterung 39 dichtend an der Eintrittsöffnung 26 an, derart, dass die Luft durch das Gitter 40 und das erste Filter 24 geführt wird. In der inaktiven Stellung ist die Filterhalterung 39 beabstandet von der Eintrittsöffnung 26 angeordnet, so dass ein direkter Luftpfad zwischen Eintrittsöffnung 26 und Austrittsöffnung 27 unter Umgehung des Filters 24 gebildet wird. Das Gitter 40 verhindert in dieser Position, dass die an der Eingangsseite des ersten Filters 24 anhaftenden Flusen vom Prozessluftstrom fortgetragen werden. FIGS. 7 and 8 show a further embodiment of the first filter 24, which is particularly suitable for arrangement in the door 3 of the device. In this embodiment, the filter is mounted in a rigid frame 38, which in turn is removably arranged in a filter holder 39 for cleaning. The filter holder 39 has on the input side a grid 40, through which the process air reaches the filter 24 in the active position of the filter. The filter holder 39 can now be reciprocated as a whole by the switching mechanism 29 between the active and the inactive position. In the active position, the filter holder 39 sealingly connects to the inlet opening 26, such that the air through the grid 40 and the first filter 24 is guided. In the inactive position, the filter holder 39 is arranged at a distance from the inlet opening 26, so that a direct air path between the inlet opening 26 and the outlet opening 27 is formed, bypassing the filter 24. In this position, the grid 40 prevents the lint adhering to the inlet side of the first filter 24 from being carried away by the process air flow.

Fig. 9 und 10 zeigt eine weitere Ausgestaltung des ersten Filters 24, bei welcher das Filter beim Umschalten zwischen dem aktiven und inaktiven Zustand nicht bewegt wird. Vielmehr ist eine Klappe 40 vorgesehen, mit welcher die Prozessluft wahlweise durch das Filter 24 oder am Filter 24 vorbei geführt werden kann. Die Klappe 40 kann von der Umschaltvorrichtung 29 bewegt werden. FIGS. 9 and 10 shows a further embodiment of the first filter 24, in which the filter is not moved when switching between the active and inactive state. Rather, a flap 40 is provided with which the process air can be selectively passed through the filter 24 or the filter 24 over. The Flap 40 can be moved by the switching device 29.

Noch eine andere Ausgestaltung des ersten Filters ist in Fig. 12 - 14 dargestellt. In dieser Ausführung ist das erste Filter 24 in einem Rahmen 60 angeordnet, der um eine Drehachse 61 drehbar ist. Drehachse 61 erstreckt sich quer, insbesondere senkrecht, zur Ebene, in welcher das Filter 24 liegt. Die Umschaltmechanik 29 ist dazu ausgestaltet, den Rahmen 60 um die Drehachse 61 zu drehen, und zwar zwischen der in Fig. 13 gezeigten aktiven Position, in welcher das Filter 24 im Filterraum 25 angeordnet ist und die durch den Filterraum 25 strömende Prozessluft filtert, und der in Fig. 14 gezeigten inaktiven Position, in welcher das Filter 24 ausserhalb des Filterraums 25 angeordnet ist.Yet another embodiment of the first filter is in Fig. 12 - 14 shown. In this embodiment, the first filter 24 is arranged in a frame 60 which is rotatable about a rotation axis 61. The axis of rotation 61 extends transversely, in particular perpendicularly, to the plane in which the filter 24 lies. The switching mechanism 29 is configured to rotate the frame 60 about the rotation axis 61, between the in Fig. 13 shown active position in which the filter 24 is arranged in the filter chamber 25 and filters the flowing through the filter chamber 25 process air, and the in Fig. 14 shown inactive position in which the filter 24 is disposed outside the filter chamber 25.

In der in Fig. 12 - 14 dargestellten Ausführung des Filters ist der Rahmen 60 ringförmig ausgebildet und das erste Filter 24 ist erstreckt sich nur über ein erstes Segment der vom Rahmen 60 umschlossenen Ringfläche, während ein zweites Segment dieser Ringfläche offen ist. Die Umschaltmechanik 29 ist beispielsweise als Drehmotor ausgestaltet, der am Rahmen 60 angreift und diesen rotiert.In the in Fig. 12 - 14 illustrated embodiment of the filter, the frame 60 is annular and the first filter 24 extends only over a first segment of the frame 60 enclosed by the annular surface, while a second segment of this annular surface is open. The switching mechanism 29 is designed, for example, as a rotary motor which engages the frame 60 and rotates it.

Die in Fig. 12 - 14 dargestellte Variante des ersten Filters eignet sich insbesondere zur Montage in der Tür 3 oder unterhalb des Türrahmens der Wäschebehandlungsvorrichtung.In the Fig. 12 - 14 illustrated variant of the first filter is particularly suitable for mounting in the door 3 or below the door frame of the laundry treatment device.

Steuerung des ersten Filters:Control of the first filter:

Wie erwähnt, wird die Umschaltvorrichtung 29 von der Steuerung 5 gesteuert, d.h. die Steuerung 5 kann festlegen, ob das erste Filter 24 aktiv oder inaktiv ist. Im Folgenden werden einige Kriterien beschrieben, aufgrund derer die Steuerung 5 die Umschaltvorrichtung 29 steuern kann.As mentioned, the switching device 29 is controlled by the controller 5, i. the controller 5 may determine whether the first filter 24 is active or inactive. In the following, some criteria will be described, on the basis of which the controller 5 can control the switching device 29.

In einer vorteilhaften Ausführung besitzt das Gerät mindestens einen Sensor 45, der in Fig. 2 beispielhaft im Luftkanal 10 nach Trommel 1 und vor Verdampfer 6 angeordnet ist. Denkbar sind jedoch auch andere Anordnungen des Sensors 45.In an advantageous embodiment, the device has at least one sensor 45, the in Fig. 2 exemplary is arranged in the air duct 10 to drum 1 and before the evaporator 6. However, other arrangements of the sensor 45 are also conceivable.

In einer ersten Ausführung kann es sich beim Sensor 45 z.B. um einen Flusensensor handeln. Unter einem Flusensensor ist dabei ein Sensor zu verstehen, der ein Signal abhängig von der Dichte der Flusen in der Prozessluft erzeugt. Ein solcher Flusensensor kann die Flusen z.B. optisch in einer Lichtschranke zählen, oder er kann die sich an einer Messfläche ablagernden Flusen detektieren. In diesem Fall ist die Steuerung 5 dazu ausgestaltet ist, die Umschaltmechanik 29 abhängig vom Signal des Flusensensors zu steuern. Zeigt der Flusensensor eine tiefe Flusenkonzentration an, so kann das erste Filter 24 in seinen inaktiven Zustand gebracht werden, um den Luftwiderstand im Gerät zu reduzieren. Steigt die Flusenkonzentration an, z.B. mit zunehmender Trocknung der Wäsche 2, so wird das erste Filter 24 zugeschaltet.In a first embodiment, the sensor 45 may be e.g. to act a lint sensor. A lint sensor is to be understood as meaning a sensor which generates a signal depending on the density of the lint in the process air. Such a lint sensor can detect the lint, e.g. optically count in a light barrier, or he can detect the deposited on a measuring surface lint. In this case, the controller 5 is configured to control the switching mechanism 29 depending on the signal of the lint sensor. If the lint sensor indicates a low lint concentration, the first filter 24 can be brought into its inactive state to reduce the air resistance in the device. When the lint concentration increases, e.g. with increasing drying of the laundry 2, the first filter 24 is switched on.

In einer zweiten Ausführung kann es sich beim Sensor 45 um einen Feuchtesensor handeln, mit welchem die Feuchte der Prozessluft oder der Wäsche gemessen wird. Es können auch zwei Feuchtesensoren verwendet werden, von denen der eine die Feuchte der Prozessluft und der andere jene er Wäsche misst. Die Steuerung 5 ist dazu ausgestaltet, die Umschaltmechanik 29 abhängig vom Signal des Feuchtesensors zu steuern. In diesem Fall wird das erste Filter 24 basierend auf der Überlegung gesteuert, dass sehr feuchte Wäsche wenig Flusen abgibt. Ist die Feuchte der Prozessluft und/oder der Wäsche hoch, wird das erste Filter 24 in seinen inaktiven Zustand gebracht. Ist sie tief, wird das erste Filter in seinen aktiven Zustand gebracht.In a second embodiment, the sensor 45 may be a humidity sensor with which the humidity of the process air or the laundry is measured. It is also possible to use two humidity sensors, one measuring the humidity of the process air and the other the laundry. The controller 5 is configured to control the switching mechanism 29 depending on the signal of the humidity sensor. In this case, the first filter 24 is controlled based on the consideration that very wet laundry gives off little lint. If the humidity of the process air and / or the laundry is high, the first filter 24 is brought into its inactive state. If it is deep, the first filter is brought into its active state.

In einer weiteren Ausführung kann es sich beim Sensor 45 um einen Temperatursensor handeln, mit welchem eine Temperatur in der Wäschebehandlungsvorrichtung gemessen wird. Die Steuerung 5 ist dazu ausgestaltet, die Umschaltmechanik 29 abhängig vom Signal des Temperatursensors zu steuern. Beim Temperatursensor handelt es sich vorzugsweise um einen Sensor, mit dem eine Temperatur im Wärmepumpenkreislauf gemessen werden kann, d.h. im Kreislauf, von welchem der Verdampfer 6 gekühlt und der Kondensator 7 erwärmt werden. Da sich eine Verschmutzung des Filters in einer Erhöhung der Gerätetemperatur, insbesondere der Temperatur im Wärmepumpenkreislauf zeigt, kann das erste Filter z.B. in seinen inaktiven Zustand gebracht werden, wenn die gemessene Temperatur im Gerät über eine vorgegebene Schwelle ansteigt.In a further embodiment, the sensor 45 may be a temperature sensor with which a temperature in the laundry treatment device is measured. The controller 5 is designed to the switching mechanism 29 depending on the signal of the temperature sensor to control. The temperature sensor is preferably a sensor with which a temperature in the heat pump cycle can be measured, ie in the circuit from which the evaporator 6 is cooled and the condenser 7 is heated. Since a contamination of the filter in an increase in the device temperature, in particular the temperature in the heat pump cycle shows, the first filter can be brought into its inactive state, for example, when the measured temperature rises in the device above a predetermined threshold.

Eine besonders bevorzugte Ausführung mit Temperatursensor im Wärmepumpenkreislauf wird in Fig. 11 illustriert. Diese Figur zeigt die wichtigsten Komponenten des Wärmepumpenkreislaufs. Der Kreislauf besitzt einen Kompressor 50, von welchem das Wärmepumpenmedium zum Kondensator 6 gefördert wird. Sodann durchläuft das Medium optional einen Zusatzwärmetauscher 51, der mit einem Lüfter 52 bedarfsweise gekühlt werden kann, um dem System Wärme zu entziehen. Dann passiert das Medium eine Drossel oder ein Expansionsventil 53 und gelangt in den Verdampfer 7, um sodann zum Kompressor 50 zurückzukehren. Der Temperatursensor 45 ist in diesem Fall vorzugsweise zwischen dem Kondensator 6 und der Drossel bzw. dem Expansionsventil 53 angeordnet. In einer besonders vorteilhaften Ausführung sind ein erster Temperatursensor 45 und ein zweiter Temperatursensor 45' vorgesehen, wobei der zweite Temperatursensor 45' zwischen dem Verdampfer 7 und dem Kompressor 50 angeordnet ist. In diesem Falle wird die Temperaturdifferenz zwischen dem ersten und dem zweiten Temperatursensor 45 bzw. 45' berechnet. Es zeigt sich, dass diese Temperaturdifferenz ein gutes Mass für die Verschmutzung des Filters ist, weshalb die Steuerung 5 dazu ausgestaltet sein kann, die Umschaltmechanik 29 abhängig von dieser Temperaturdifferenz zu steuern. Je grösser die Temperaturdifferenz wird, desto höher ist die Verschmutzung. Vorteilhaft wird also das erste Filter abhängig von dieser Temperaturdifferenz gesteuert. Liegt die Temperaturdifferenz über einer Schwelle, so wird das Filter in den inaktiven Zustand gebracht.A particularly preferred embodiment with temperature sensor in the heat pump cycle is in Fig. 11 illustrated. This figure shows the most important components of the heat pump cycle. The circuit has a compressor 50, from which the heat pump medium is conveyed to the condenser 6. Then, the medium optionally passes through an additional heat exchanger 51, which can be cooled with a fan 52, if necessary, to extract heat from the system. Then, the medium passes through a throttle or an expansion valve 53 and enters the evaporator 7, to then return to the compressor 50. The temperature sensor 45 is in this case preferably arranged between the condenser 6 and the throttle or the expansion valve 53. In a particularly advantageous embodiment, a first temperature sensor 45 and a second temperature sensor 45 'are provided, wherein the second temperature sensor 45' is arranged between the evaporator 7 and the compressor 50. In this case, the temperature difference between the first and second temperature sensors 45 and 45 'is calculated. It turns out that this temperature difference is a good measure of the contamination of the filter, which is why the controller 5 may be configured to control the switching mechanism 29 depending on this temperature difference. The bigger the temperature difference, the higher the pollution. Advantageously, therefore, the first filter is controlled depending on this temperature difference. Lies the temperature difference above a threshold, the filter is brought into the inactive state.

Weiter ist es möglich, auch mehrere Arten von Sensoren, z.B. einen Flusen- und einen Feuchtesensor, zu kombinieren.Further, it is also possible to use several types of sensors, e.g. a lint and a humidity sensor to combine.

Weiter kann die Steuerung des ersten Filters 24 auch aufgrund der jeweiligen Prozessphase erfolgen, d.h. die Steuerung 5 berücksichtigt zusätzlich oder alternativ zum Signal eines Sensors auch die Phase, in welcher sich der jeweilige Trocknungsprozess befindet.Furthermore, the control of the first filter 24 may also be due to the respective process phase, i. In addition or as an alternative to the signal of a sensor, the controller 5 also takes into account the phase in which the respective drying process is located.

Insbesondere kann die Steuerung 5 dazu ausgestaltet sein, in einer ersten Phase eines Trocknungsprozesses der Wäsche 2 die Prozessluft am ersten Filter 24 vorbeizuführen und in einer zweiten Phase des Trocknungsprozesses die Prozessluft durch das erste Filter hindurchzuführen. Innerhalb einem Trocknungsprozess kann also das erste Filter mindestens einmal vom aktiven in den inaktiven Zustand oder vom inaktiven in den aktiven Zustand umgeschaltet werden. Dabei liegt die erste Phase, in welcher das erste Filter inaktiv ist, vorteilhaft zeitlich vor der zweiten Phase, da zu Beginn des Trocknungsprozesses die Wäsche normalerweise noch sehr feucht ist und kaum zur Flusenbildung neigt. In der späteren, zweiten Phase, wenn die Wäsche trockener ist und vermehrt Flusen bildet, führt die Steuerung 5 sodann die Prozessluft durch das erste Filter 24.In particular, the controller 5 may be configured to pass the process air past the first filter 24 in a first phase of a drying process of the laundry 2 and to pass the process air through the first filter in a second phase of the drying process. Within a drying process, therefore, the first filter can be switched at least once from the active to the inactive state or from the inactive to the active state. In this case, the first phase, in which the first filter is inactive, advantageously before the second phase, since at the beginning of the drying process, the laundry is usually still very moist and hardly prone to linting. In the later, second phase, when the laundry is drier and increasingly forms lint, the controller 5 then passes the process air through the first filter 24.

Den Übergang zwischen der genannten ersten und zweiten Phase des Trocknungsprozesses, d.h. der Zeitpunkt, zu welchem das Filter 24 aktiviert wird, kann die Steuerung 5 abhängig von einem Sensorsignal, insbesondere abhängig vom Signal des oben erwähnten Flusen- oder Feuchtesensors, festlegen. Alternativ dazu kann der Übergang auch abhängig von der Prozesszeit (d.h. der Zeit seit Anfang des Trocknungsprozesses) festgelegt werden. Denkbar ist auch eine Entscheidung, welche von Prozesszeit und Sensorsignal abhängt (z.B. wird die zweite Phase eingeleitet, sobald die Feuchtigkeit der Luft oder Wäsche unter einen Grenzwert abfällt oder die Prozesszeit einen bestimmten Wert erreicht, je nachdem, was früher eintritt).The transition between said first and second phase of the drying process, ie the time at which the filter 24 is activated, the controller 5 depending on a sensor signal, in particular depending on the signal of the above-mentioned lint or moisture sensor set. Alternatively, the transition may also be determined depending on the process time (ie the time since the beginning of the drying process). Also conceivable is a decision which depends on process time and sensor signal (eg, the second phase is initiated as soon as the humidity of the air or laundry falls below a threshold or the process time reaches a certain value, whichever comes first).

Weiter kann der Benutzer auch die Möglichkeit erhalten, auf die Aktivierung bzw. Deaktivierung des ersten Filters Einfluss zu nehmen. Insbesondere kann ihm eine Programmoption zur Verfügung gestellt werden, welche die Deaktivierung des ersten Filters ermöglicht oder verhindert. Oder er kann ein besonders schnelles Programm anwählen, welches das erste Filter während der ganzen Prozessdauer oder zumindest während eines grossen Teils der Prozessdauer deaktiviert. In diesem Fall kann das Gerät den Benutzer darauf aufmerksam machen, dass das ein nachfolgendes, stationäres zweites Filter nach Prozessende zu reinigen ist.Furthermore, the user can also be given the opportunity to influence the activation or deactivation of the first filter. In particular, a program option can be made available to him which enables or prevents the deactivation of the first filter. Or he can select a particularly fast program which deactivates the first filter during the entire process duration or at least during a large part of the process duration. In this case, the device can alert the user that a subsequent, stationary second filter is to be cleaned after the end of the process.

Verschmutzungserkennung:Pollution detection:

Ein erstes Filter der beschriebenen Art kann in besonders einfacher Weise auf Verschmutzung geprüft werden. Hierzu kann die Steuerung 5 so ausgestaltet werden, dass sie die Strömungsgeschwindigkeit der Prozessluft und/oder die Leistungsaufnahme des Ventilators 9 misst, und zwar einmal bei inaktivem Filter 24 und einmal bei aktivem Filter 24. Der Unterschied der Strömungsgeschwindigkeit der Prozessluft sowie die Leistungsaufnahme des Ventilators sind ein Mass für die Verschmutzung des Filters. Ist diese Verschmutzung hoch, so sinkt die Strömungsgeschwindigkeit der Prozessluft beim Zuschalten des ersten Filters 24 stärker ab bzw. die Leistungsaufnahme des Ventilators 8 steigt stärker an als bei weniger verschmutztem Filter. Durch eine entsprechende Messung, z.B. gegen Ende des Trocknungsprozesses, kann die Steuerung den Verschmutzungsgrad des ersten Filters 24 erkennen und den Benutzer gegebenenfalls zu einer Reinigung auffordern.A first filter of the type described can be tested for contamination in a particularly simple manner. For this purpose, the controller 5 can be configured so that it measures the flow rate of the process air and / or the power consumption of the fan 9, once with inactive filter 24 and once with active filter 24. The difference in the flow rate of the process air and the power consumption of the fan are a measure of the pollution of the filter. If this contamination is high, the flow rate of the process air drops more when the first filter 24 is switched on, or the power consumption of the fan 8 increases more than that of the less polluted filter. By a corresponding measurement, e.g. Towards the end of the drying process, the controller may detect the level of soiling of the first filter 24 and prompt the user for cleaning if necessary.

Bemerkungen:Remarks:

Wie bereits erwähnt, kann nebst dem zu- und wegschaltbaren ersten Filter mindestens ein zweites, fest im Luftstrom angeordnetes Filter vorgesehen sein. So kann z.B. das Türfilter 20 und/oder das Rahmenfilter 21 als erstes, d.h. bewegliches Filter ausgestaltet werden, während mindestens eines der anderen Filter, insbesondere das Endfilter 22, fest im Luftstrom angeordnet ist. Vorzugsweise ist dabei das zweite, feste Filter dem ersten, wegschaltbaren Filter nachgeschaltet, d.h. der Prozessluftstrom durchläuft zuerst das erste und sodann das zweite Filter, bevor zum Verdampfer 6 gelangt, so dass allfällige Flusen, die sich vom ersten Filter in seiner inaktiven Stellung lösen, noch vom zweiten Filter aufgefangen werden.As already mentioned, in addition to the first filter which can be switched on and off, at least one second filter fixedly arranged in the air flow can be provided. Thus, e.g. the door filter 20 and / or the frame filter 21 as the first, i. movable filter are designed while at least one of the other filter, in particular the final filter 22, is fixedly arranged in the air flow. Preferably, the second, fixed filter is connected downstream of the first, wegschaltbaren filter, i. the process air stream passes first through the first and then the second filter before it reaches the evaporator 6, so that any lint that dissolves from the first filter in its inactive position, are still caught by the second filter.

Indem ein erstes Filter vorgesehen wird, welches wahlweise inaktiv oder aktiv geschaltet werden kann, ergeben sich also verschiedene Möglichkeiten zum Verbessern des Betriebs des Geräts. So kann der Energieverbrauch reduziert werden, indem das Filter bei Nichtgebrauch aus dem Prozessluftstrom entfernt wird. Weiter kann eine Verschmutzung des Filters erkannt werden.Thus, by providing a first filter which can be selectively disabled or actively switched, there are various possibilities for improving the operation of the device. Thus, the energy consumption can be reduced by the filter is removed from the process air stream when not in use. Furthermore, contamination of the filter can be detected.
