Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft einen Wäschetrockner, insbesondere einen Schranktrockner, zum Trocknen von Wäsche sowie ein Verfahren zum Betrieb eines solchen Geräts.The invention relates to a tumble dryer, in particular a cabinet dryer, for drying laundry and a method for operating such a device.

Hintergrundbackground

Wäschetrockner mit einer Prozessluftaufbereitung umfassend eine Wärmepumpe, mit welcher eine Heizvorrichtung und eine Kühlvorrichtung betrieben werden, sind grundsätzlich bekannt. In solchen Geräten wird die Prozessluft zur Aufbereitung zunächst durch die Kühlvorrichtung geführt, wo ihr Wasser entzogen wird, und sodann durch die Heizvorrichtung, wo sie wieder erwärmt wird. Es ist ein Prozessluftkreislauf vorgesehen, um die Prozessluft in einem Kreislauf durch einen Nutzraum (bzw. Bottich) des Geräts und die Prozessluftaufbereitung zu führen.Dryers with a process air treatment comprising a heat pump, with which a heating device and a cooling device are operated, are basically known. In such devices, the processing air for treatment is first passed through the cooling device, where its water is withdrawn, and then through the heater, where it is reheated. A process air circuit is provided in order to circulate the process air through a useful space (or tub) of the device and the process air treatment.

Die Kühlvorrichtung und die Heizvorrichtung sind in der Regel als Wärmetauscher ausgeführt, welche der Prozessluft eine grosse Kontaktoberfläche bieten. Dies führt allerdings zu Problemen, z.B. aufgrund des hieraus resultierenden hohen Strömungswiderstands.The cooling device and the heater are usually designed as a heat exchanger, which provide the process air a large contact surface. However, this leads to problems, eg due to the resulting high flow resistance.

Darstellung der ErfindungPresentation of the invention

Es stellt sich deshalb die Aufgabe, die oben genannten Probleme zu reduzieren.It is therefore the task to reduce the above problems.

Diese Aufgabe wird durch das Gerät und das Verfahren gemäss den unabhängigen Ansprüchen erfüllt.This object is achieved by the apparatus and the method according to the independent claims.

Demgemäss bildet die Prozessluftaufbereitung zwei Kanäle, welche strömungstechnisch parallel angeordnet sind, d.h. die zwei Kanäle beginnen an einem gemeinsamen Startort und enden an einem gemeinsamen Zielort (sie brauchen aber nicht im geometrischen Sinne parallel zu verlaufen). Den beiden Kanälen ist eine Umschaltvorrichtung zugeordnet, welche dazu ausgestaltet ist, die Prozessluft wahlweise durch den ersten oder den zweiten Kanal zu führen. Die Kühlvorrichtung und die Heizvorrichtung sind nur im ersten Kanal angeordnet. Diese Anordnung hat den Vorteil, dass in Prozessphasen, in denen die Kühlvorrichtung und die Heizvorrichtung nicht oder nur reduziert benötigt werden, mindestens ein Teil der Prozessluft durch den zweiten Kanal an der Kühl- und Heizvorrichtung vorbei geführt werden kann. Dadurch sinkt in diesen Prozessphasen der Energiebedarf und/oder es können grössere Prozessluftströme erzeugt werden. Weiter kann auch die Lärmentwicklung reduziert werden, und die Heizvorrichtung und Kühlvorrichtung sind weniger Verschmutzungsprozessen ausgesetzt.Accordingly, the process air treatment forms two channels, which are fluidically arranged in parallel, i. the two channels start at a common starting point and end at a common destination (but they do not need to be parallel in a geometric sense). The two channels are assigned a switching device which is configured to selectively guide the process air through the first or the second channel. The cooling device and the heating device are arranged only in the first channel. This arrangement has the advantage that in process phases in which the cooling device and the heating device are not required or only reduced, at least a portion of the process air can be passed through the second channel to the cooling and heating device. As a result, the energy requirement decreases in these process phases and / or larger process air streams can be generated. Furthermore, the noise development can be reduced, and the heater and cooling device are exposed to less pollution processes.

Die Anordnung des zweiten Kanals ist aus Platzgründen vorzugsweise unterhalb oder oberhalb des ersten Kanals, sie kann aber auch seitlich des ersten Kanals sein.The arrangement of the second channel is for reasons of space preferably below or above the first channel, but it may also be laterally of the first channel.

In einem Wäscheaufbereitungsprozess umfassend eine Trocknungsphase und eine Aufbereitungsphase kann ein so ausgestaltetes Gerät vorteilhaft wie folgt betrieben werden:

  • In der Trocknungsphase wird der zweite Kanal von der Umschaltvorrichtung blockiert, so dass im Wesentlichen alle Luft im Prozessluftkreislauf durch den ersten Kanal fliesst. So kann die Luft getrocknet und wieder erwärmt werden.
  • In der Aufbereitungsphase, welche der Trocknungsphase vor- oder nachgeschaltet sein kann und in der z.B. Schritte zur Geruchsverminderung und/oder Entkeimung durchgeführt werden, wird der zweite Kanal nicht blockiert, so dass mindestens ein Teil der Prozessluft im Prozessluftkreislauf durch den zweiten Kanal fliesst.
In a laundry treatment process comprising a drying phase and a preparation phase, a device designed in this way can advantageously be operated as follows:
  • In the drying phase of the second channel is blocked by the switching device, so that essentially all the air in the process air circulation through the first channel flows. So the air can be dried and reheated.
  • In the preparation phase, which may be upstream or downstream of the drying phase and in which, for example, steps for odor reduction and / or sterilization are performed, the second channel is not blocked, so that at least part of the process air flows through the second channel in the process air cycle.

Vorzugsweise ist das Gerät mit einer Zusatzheizung zusätzlich zur Heizvorrichtung ausgestattet. Das Gerät ist in diesem Fall dazu ausgestaltet, zumindest in einer Prozessphase (z.B. der oben genannten Aufbereitungsphase) die Prozessluft durch den zweiten Kanal zu führen und die Zusatzheizung zu betreiben. Auf diese Weise kann die Prozessluft auch dann geheizt werden, wenn sie durch den zweiten Kanal geführt wird.Preferably, the device is equipped with an additional heater in addition to the heater. In this case, the device is designed to guide the process air through the second channel and to operate the additional heating, at least in one process phase (for example the above-mentioned preparation phase). In this way, the process air can be heated even if it is passed through the second channel.

In einer bevorzugten Ausführung ist der Wäschetrockner als Trockenschrank ausgestaltet. In einem solchen Trockenschrank wird die Wäsche im Nutzraum aufgehängt. Hierzu sind im Nutzraum geeignete Aufhängemittel vorgesehen.In a preferred embodiment, the tumble dryer is designed as a drying oven. In such a drying cabinet, the laundry is hung in the utility room. For this purpose, suitable suspension means are provided in the useful space.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

Weitere Ausgestaltungen, Vorteile und Anwendungen der Erfindung ergeben sich aus den abhängigen Ansprüchen und aus der nun folgenden Beschreibung anhand der Figur, welche einen Schnitt durch eine Ausgestaltung eines Schranktrockners zeigt.Further embodiments, advantages and applications of the invention will become apparent from the dependent claims and from the following description with reference to the figure, which shows a section through an embodiment of a cabinet dryer.

Wege zur Ausführung der ErfindungWays to carry out the invention Schranktrockner:Cabinet dryer:

  • Fig. 1 zeigt einen Schnitt durch einen Wäschetrockner in Form eines Schranktrockners mit einem Nutzraum 1 zur Aufnahme der Wäsche 2. Der Nutzraum 1 wird vorderseitig von einer Türe 3 verschlossen. In der gezeigten Ausführung befinden sich im Bodenbereich des Nutzraums eine oder mehrere Öffnungen 4, in welcher bzw. welchen ein erstes Filter 5 angeordnet ist. An die Öffnung 4 schliesst eine Prozessluftaufbereitung 6 an, in welcher die Prozessluft über eine Umschaltvorrichtung 30, zwei strömungstechnisch parallele Kanäle 31, 32, einen Ventilator 9, vorbei an einer UV-Lichtquelle 10 in einen Deckenbereich 12 des Geräts geführt wird. Der Deckenbereich 12 ist über Öffnungen 14 in der Decke 15 des Nutzraums 1 mit dem Nutzraum 1 verbunden. Fig. 1 shows a section through a tumble dryer in the form of a cabinet dryer with a usable space 1 for receiving the laundry 2. The work space 1 is closed on the front side by a door 3. In the embodiment shown, one or more openings 4 are located in the bottom area of the work space, in which or which a first filter 5 is arranged. To the opening 4 includes a process air treatment 6, in which the process air via a switching device 30, two fluidically parallel channels 31, 32, a fan 9, passing a UV light source 10 in a ceiling portion 12 of the device. The ceiling area 12 is connected via openings 14 in the ceiling 15 of the work space 1 with the work space 1.

Weiter besitzt das Gerät einen Dampfgenerator 18 zum Einführen von Dampf in die Prozessluft. In der vorliegenden Ausführung ist der Dampfgenerator 18 so angeordnet, dass er Dampf von unten in den Nutzraum einleitet, so dass der Dampf (der wärmer als die Prozessluft ist) nach oben durch die Wäsche steigen kann. Mit dem Dampf sowie mit dem Heizgerät werden das Gerät und die Textilien vorzugsweise auf mindestens 70°C (kann auch weniger sein) erhitzt und so hygienisiert. Durch das Erwärmen in Verbindung mit dem Luftstrom werden die Knitter entfernt. Von besonderem Vorteil ist die Dampfbehandlung bei trockenen Textilien, da die leichte Befeuchtung und Erwärmung durch den Dampf das Entknittern stark verbessert und einen weiteren Beitrag zum Auffrischen leistet.Further, the apparatus has a steam generator 18 for introducing steam into the process air. In the present embodiment, the steam generator 18 is arranged to introduce steam from below into the work space so that the steam (which is warmer than the process air) may rise up through the wash. With the steam and with the heater, the device and the textiles are preferably heated to at least 70 ° C (may be less) and thus sanitized. Heating in conjunction with the airflow removes the creases. Of particular advantage is the steam treatment in dry textiles, since the slight humidification and heating by the steam greatly improves the Entknittern and makes a further contribution to the refreshment.

Das beschriebene Gerät bildet einen vorzugsweise im Wesentlichen geschlossenen Prozessluftkreislauf, in welchem Prozessluft durch den Nutzraum 1 und die Prozessluftaufbereitung 6 wieder zurück in den Nutzraum 1 geführt wird.The device described forms a preferably substantially closed process air cycle, in which process air is guided back into the work space 1 through the work space 1 and the process air treatment 6.

Die Umschaltvorrichtung 30 ist in der gezeigten Ausführung den beiden Kanälen 31, 32 vorgeschaltet und umfasst in der gezeigten Ausführung eine Klappe 33, mit welcher wahlweise einer der beiden Kanäle 31, 32 ganz oder teilweise blockiert werden kann. In einem ersten der beiden Kanäle, nämlich Kanal 31, sind nacheinander eine Kühlvorrichtung 7 und eine Heizvorrichtung 8 angeordnet. Vor der Kühl- und der Heizvorrichtung 7 bzw. 8 ist im ersten Kanal 31 ein Flusenfilter 34 vorgesehen, um zu verhindern, dass sich Flusen in der Kühl- und der Heizvorrichtung 7 bzw. 8 verfangen. Das Flusenfilter kann auch zur Zurückhaltung von Partikeln aus den Duftstoffen dienen, die die Wärmetauscher schädigen. Im zweiten Kanal 32 wird kein derartiger Flusenfilter benötigt, oder zumindest genügt ein grobmaschigerer Filter (z.B. Filter 5).The switching device 30 is connected upstream of the two channels 31, 32 in the embodiment shown and, in the embodiment shown, comprises a flap 33 with which either one of the two channels 31, 32 can be completely or partially blocked. In a first of the two channels, namely channel 31, a cooling device 7 and a heating device 8 are successively arranged. In front of the cooling and heating devices 7 and 8, a lint filter 34 is provided in the first channel 31 to prevent lint from getting caught in the cooling and heating devices 7 and 8, respectively. The lint filter can also serve to retain particles from the fragrances that damage the heat exchangers. In the second channel 32, no such lint filter is needed, or at least a coarse-meshed filter (eg, filter 5) is sufficient.

Unterhalb der Kühlvorrichtung 7 befindet sich ein Auffangbecken 20 zum Auffangen von auskondensiertem Wasser. Von dort kann das Wasser automatisch über eine Pumpvorrichtung 21 oder manuell entleert werden.Below the cooling device 7 is a catch basin 20 for collecting condensed water. From there, the water can be automatically drained via a pumping device 21 or manually.

In der Kühlvorrichtung 7 wird die Luft abgekühlt, um Feuchte auszukondensieren. Danach wird die Luft in der Heizvorrichtung 8 wieder erwärmt, so dass sie neue Feuchtigkeit aufnehmen kann.In the cooling device 7, the air is cooled to condense out moisture. Thereafter, the air in the heater 8 is reheated so that it can absorb new moisture.

Die Kühlvorrichtung 7 und die Heizvorrichtung 8 werden von einer Wärmepumpe betrieben (nicht gezeigt). Dabei ist der Kondensator der Wärmepumpe thermisch mit der Heizvorrichtung 8 gekoppelt und der Verdampfer mit der Kühlvorrichtung 7.The cooling device 7 and the heating device 8 are operated by a heat pump (not shown). In this case, the condenser of the heat pump is thermally coupled to the heating device 8 and the evaporator to the cooling device 7.

Der Ventilator 9 dient dazu, die Luft durch den Prozessluftkreislauf umzuwälzen.The fan 9 serves to circulate the air through the process air circuit.

Die UV-Lichtquelle 10 baut organische Verbindungen ab, entweder direkt oder über eine Ozonbildung oder Photokatalyse bei ca. 356 - 390 nm. UV-Strahlung bei 185 nm erzeugt Ozon aus dem Sauerstoff der Prozessluft. Oxidierbare Laststoffe werden auf diese Weise abgebaut und dauerhaft neutralisiert. Erzeugt die UV-Lichtquelle Licht mit einer Wellenlänge von z.B. 254 nm, so schädigt sie die DNA von Zellen und Keimen.The UV light source 10 breaks down organic compounds, either directly or via ozone formation or photocatalysis at about 356-390 nm. UV radiation at 185 nm generates ozone from the oxygen in the process air. Oxidizable substances are degraded in this way and permanently neutralized. If the UV light source produces light with a wavelength of e.g. 254 nm, it damages the DNA of cells and germs.

Anstelle der oder zusätzlich zur UV-Lichtquelle kann auch ein Ozongenerator vorgesehen sein, der Ozon beispielsweise über hohe elektrische Felder erzeugt.Instead of or in addition to the UV light source, it is also possible to provide an ozone generator which generates ozone, for example, via high electric fields.

Vorzugsweise ist der UV-Lichtquelle bzw. dem Ozongenerator ein Sensor nachgeschaltet, der die Ozonkonzentration misst und so regelt, dass sie einen vorgegebenen Wert nicht übersteigt.Preferably, the UV light source or the ozone generator is followed by a sensor which measures the ozone concentration and regulates so that it does not exceed a predetermined value.

Weiter besitzt der Schranktrockner vorzugsweise einen Duftspender 24 zur Abgabe von Duftstoffen.Next, the cabinet dryer preferably has a fragrance dispenser 24 for dispensing fragrances.

Dabei kann es sich in einer einfachen Ausführung z.B. um ein saugfähiges Material handeln, welches mit einem Duftstoff, beispielsweise einem ätherischen Öl, getränkt ist. Denkbar ist jedoch z.B. auch ein geheizter Verdampfer oder eine Sprühvorrichtung. Der Duftspender 24 kann so angeordnet sein, dass er ein Parfüm direkt in den Nutzraum 1 abgibt, oder er kann es auch in die Prozessluftaufbereitung 6 abgeben, vorzugsweise nach der UV-Lichtquelle 10 bzw. dem Ozongenerator.In this case, in a simple embodiment, it may be e.g. to act an absorbent material, which is impregnated with a fragrance, such as an essential oil. However, it is conceivable, e.g. also a heated evaporator or a spraying device. The fragrance dispenser 24 can be arranged so that it emits a perfume directly into the work space 1, or he can also give it into the process air treatment 6, preferably after the UV light source 10 and the ozone generator.

Vorzugsweise ist der Prozessluftkreislauf so ausgestaltet, dass er mindestens einen Teil der Prozessluft von oben in den Nutzraum 1 einleitet. Dies geschieht in der Ausführung nach Fig. 1 über die Öffnungen 14. Denkbar ist jedoch auch, dass die Prozessluft mindestens teilweise von unten, von den Seiten oder den Ecken in den Nutzraum eingeleitet wird.Preferably, the process air circuit is configured so that it introduces at least a portion of the process air from above into the work space 1. This happens in the execution after Fig. 1 However, it is also conceivable that the process air is introduced at least partially from below, from the sides or the corners into the work space.

Weiter besitzt das Gerät vorzugsweise eine Zusatzheizung 35, deren Aufgabe weiter unten beschrieben wird. Vorzugsweise ist diese Zusatzheizung 35 in der Luftaufbereitung 6 in Strömungsrichtung nach den Kanälen 31, 32 angeordnet.Next, the device preferably has an additional heater 35, whose task will be described below. Preferably, this additional heater 35 is arranged in the air treatment 6 in the flow direction after the channels 31, 32.

Um die Knitterbildung weiter zu reduzieren und die Trocknung zu verbessern, wird die Prozessluft vorzugsweise zumindest zeitweise mit einer derartigen Strömungsgeschwindigkeit in den Nutzraum 1 eingeleitet, dass die Wäsche zu flattern beginnt. Von Vorteil wird die Luftgeschwindigkeit in einem Bereich von 2 .. 10m/s eingestellt.In order to further reduce creasing and to improve drying, the process air is preferably introduced at least temporarily into the work space 1 at such a flow rate that the laundry begins to flutter. Advantageously, the air speed is set in a range of 2 .. 10m / s.

Vorzugsweise ist der Nutzraum 1 über eine kleine Öffnung permanent mit der Umgebung verbunden, so dass der Druck im Innern des Nutzraums im Wesentlichen dem Umgebungsdruck entspricht, so dass die Türe 3 einfach geöffnet und geschlossen werden kann. Die übrigen Teile des Prozessluftkreislaufs sind hingegen nicht mit der Umgebung verbunden.Preferably, the working space 1 is permanently connected to the environment via a small opening, so that the pressure in the interior of the working space substantially corresponds to the ambient pressure, so that the door 3 can be easily opened and closed. The remaining parts of the process air cycle, however, are not connected to the environment.

Weiter ist eine Steuerung vorgesehen (nicht gezeigt), welche dazu ausgestaltet ist, den Wäschetrockner mit den hier beschriebenen Prozessschritten zu steuern.Further, a controller (not shown) is provided which is configured to control the clothes dryer with the process steps described herein.

Betrieb von Kühl- und Heizvorrichtung:Operation of cooling and heating device:

Werden die Kühl- und Heizvorrichtung 7 bzw. 8 benötigt, z.B. während einer Trocknungsphase, so wird die Umschaltvorrichtung 30 vorzugsweise so eingestellt, dass die ganze oder zumindest ein grosser Teil der Prozessluft durch den ersten Kanal 31 fliesst. Gleichzeitig ist die Wärmepumpe in Betrieb, so dass die Luft in der Kühlvorrichtung 7 getrocknet und in der Heizvorrichtung 8 wieder erwärmt werden kann.If the cooling and heating devices 7 and 8 are required, e.g. During a drying phase, the switching device 30 is preferably adjusted so that all or at least a large part of the process air flows through the first channel 31. At the same time, the heat pump is in operation so that the air in the cooling device 7 can be dried and reheated in the heating device 8.

Werden die Kühl- und Heizvorrichtung nicht benötigt, z.B. während einer Aufbereitungsphase, in welcher die Luft nicht getrocknet werden muss, so wird die Umschaltvorrichtung 30 vorzugsweise so eingestellt, dass alle oder zumindest ein grosser Teil der Prozessluft durch den zweiten Kanal 32 fliesst. In diesem Fall ist die Wärmepumpe vorzugsweise nicht in Betrieb. Da der Strömungswiderstand im zweiten Kanal 32 kleiner ist als im ersten Kanal 31, kann in diesem Fall bei gleicher Lüfterleistung mehr Prozessluft durch die Prozessluftaufbereitung 6 geführt werden, oder es kann bei reduzierter Lüfterleistung und reduzierter Lärmentwicklung gleichviel Prozessluft durch die Prozessluftaufbereitung 6 geführt werden.If the cooling and heating device are not needed, e.g. During a treatment phase in which the air does not have to be dried, the switching device 30 is preferably adjusted so that all or at least a large part of the process air flows through the second channel 32. In this case, the heat pump is preferably not in operation. Since the flow resistance in the second channel 32 is smaller than in the first channel 31, more process air can be passed through the process air treatment 6 in this case with the same fan power, or it can be performed by the process air treatment 6 with reduced fan power and reduced noise equally process air.

Insbesondere kann z.B. während mindestens eines Teils der Aufbereitungsphase ein grösserer Luftstrom durch die Prozessluftaufbereitung 6 geführt werden als während der Trocknungsphase, z.B. um die Wäsche in der oben beschriebenen Weise zum Flattern zu bringen oder eine Entkeimung und/oder Desodorierung durchzuführen.In particular, during at least part of the treatment phase, for example, a larger air flow can be conducted through the process air treatment 6 than during the drying phase, eg, around the laundry in the process Fluttering as described above or perform a sterilization and / or deodorization.

Ist der zweite Kanal 32 geöffnet, so kann die Prozessluft mit der Heizvorrichtung 8 nur ineffizient oder gar nicht geheizt werden. Um auch in diesem Fall ein Aufheizen der Prozessluft zu ermöglichen, kann diese mit der Zusatzheizung 35 erwärmt werden. Deshalb ist die Steuerung des Gerätes vorzugsweise dazu ausgestaltet, zumindest in einer Prozessphase (z.B. während mindestens eines Teils der oben erwähnten Aufbereitungsphase) die Prozessluft durch den zweiten Kanal 32 zu führen und gleichzeitig die Zusatzheizung 35 zu betreiben. Die Klappe 33 kann auch mehrere Stellungen haben um eine grösserer Prozessfreiheit zu erhalten, bzgl. der Volumenströme. Ebenfalls ist auch vorstellbar, dass der Kanal 31 nicht unbedingt verschlossen werden muss, wenn Kanal 32 in Betrieb ist, da Kanal 31 einen höheren Widerstand hat und damit automatisch die Luft durch Kanal 32 strömt.If the second channel 32 is opened, the process air with the heating device 8 can only be heated inefficiently or not at all. In order to enable a heating of the process air in this case, this can be heated with the additional heater 35. Therefore, the controller of the apparatus is preferably configured to guide the process air through the second channel 32 and simultaneously operate the auxiliary heater 35, at least in one process phase (e.g., during at least part of the above-mentioned conditioning phase). The flap 33 can also have several positions to obtain a greater freedom of process, with respect to the volume flows. It is also conceivable that the channel 31 does not necessarily have to be closed when channel 32 is in operation, since channel 31 has a higher resistance and thus automatically the air flows through channel 32.

Umschaltvorrichtung:switching:

Wie erwähnt, besitzt die Umschaltvorrichtung 30 gemäss Fig. 1 eine Klappe 33 oder einen anders gearteten Verschlussmechanismus. Mit diesem Verschlussmechanismus kann zumindest der zweite Kanal 32 blockiert werden, so dass die Prozessluft durch den ersten Kanal 31 (der einen höheren Strömungswiderstand besitzt) gezwungen werden kann. Sobald der Verschlussmechanismus den zweiten Kanal 32 freigibt, wird zumindest ein grosser Teil der Prozessluft durch diesen ausweichen, da dort der Strömungswiderstand geringer ist.As mentioned, the switching device 30 has according to Fig. 1 a flap 33 or a different type of closure mechanism. With this shutter mechanism, at least the second passage 32 can be blocked, so that the process air can be forced through the first passage 31 (having a higher flow resistance). As soon as the closure mechanism releases the second channel 32, at least a large part of the process air will escape through it, because there the flow resistance is lower.

Vorzugsweise kann mit dem Verschlussmechanismus wahlweise der erste oder der zweite Kanal blockiert werden, so dass bei Bedarf ein Luftstrom durch den ersten Kanal 31 völlig unterbunden werden kann. Hierzu besitzt die Klappe 33 der Ausführung nach Fig. 1 zwei Stellungen, von denen in Fig. 1 die Eine (bei welcher der erste Kanal 31 verschlossen ist) gestrichelt dargestellt ist, während die Andere (bei welcher der zweite Kanal 32 verschlossen ist) durchgezogen dargestellt ist.Preferably, the first or the second channel can optionally be blocked with the closure mechanism, so that, if required, an air flow through the first channel 31 can be completely prevented. For this purpose, the flap 33 according to the embodiment Fig. 1 two positions, of which in Fig. 1 the one (in which the first channel 31 is closed) is shown in dashed lines, while the other (in which the second channel 32 is closed) is shown in solid.

Mittel zum Abbauen von GeruchsstoffenMeans for breaking down odors

In einer bevorzugten Ausführung besitzt der Schranktrockner Mittel zum Abbauen von Geruchsstoffen, wie sie z.B. durch Bakterien gebildet werden.In a preferred embodiment, the cabinet dryer has means for degrading odorous substances, as e.g. be formed by bacteria.

Dabei kann es sich beispielsweise um Mittel zum Beimischen von Enzymen handeln, mit denen Geruchsstoffe abgebaut werden. Geeignete Enzyme sind beispielsweise Hydrolasen, insbesondere Esterasen, oder Oxireduktasen. Entweder wird die Prozessluft durch ein mit den o.g. Enzymen versetztes Trägermaterial hindurchgeführt, oder eine in Wasser fein verteilte Enzymmischung wird dem Prozessluftstrom zugeführt.These may, for example, be agents for adding enzymes with which odorous substances are broken down. Suitable enzymes are, for example, hydrolases, in particular esterases, or oxireductases. Either the process air is replaced by a with the o.g. Enzyme displaced carrier material passed, or a finely divided in water enzyme mixture is fed to the process air stream.

Alternativ oder zusätzlich hierzu kann auch ein Photokatalysator und eine Lichtquelle zum Aktivieren des Photokatalysator vorgesehen sein; wie z.B. ein Photokatalysator umfassend TiO2. Der Benutzer kann die Mittel zum Abbauen von Geruchsstoffen optional durch eine Funktion auf dem Bedienpanel steuern.Alternatively or additionally, a photocatalyst and a light source for activating the photocatalyst may also be provided; such as a photocatalyst comprising TiO 2 . The user can optionally control the means for degrading odors by a function on the control panel.

Unter "Photokatalysator" wird ein Stoff verstanden, der bei Beleuchtung mit Licht geeigneter Wellenlänge, insbesondere sichtbarem oder ultraviolettem Licht, als Katalysator wirkt."Photocatalyst" is understood to mean a substance which acts as a catalyst when illuminated with light of suitable wavelength, in particular visible or ultraviolet light.

Der Photokatalysator ist vorzugsweise ein Katalysator auf der Basis von Titanoxid mit UV-Strahlung, d.h. ein Katalysator, der z.B. TiO2 (Titandioxid) enthält, denkbar sind beispielsweise jedoch auch Katalysatoren basierend auf CdS (Kadmiumsulfid), WO3 (Wolframoxid) oder ZO (Zinkoxid). Geeignete Fotokatalysatoren sind beispielsweise in DE 20 2004 005 677 U1 und EP 1 205 244 beschrieben. Sie erzeugen bei Lichtabsorption Elektronen und Löcher und induzieren dadurch chemische Reaktionen, welche organische Verbindungen abbauen und Mikroorganismen Viren, Bakterien und Keime abzutöten vermögen. Besonders bevorzugt sind Katalysatoren auf der Basis von Titandioxid aufgrund der hohen Effizienz und biologischen Verträglichkeit dieses Materials.The photocatalyst is preferably a catalyst based on titanium oxide with UV radiation, ie a catalyst which contains, for example, TiO 2 (titanium dioxide); conceivable, however, are also catalysts based on CdS (cadmium sulfide), WO 3 (tungsten oxide) or ZO ( Zinc oxide). Suitable photocatalysts are, for example, in DE 20 2004 005 677 U1 and EP 1 205 244 described. They produce electrons and holes when absorbed by light, thereby inducing chemical reactions that degrade organic compounds and enable microorganisms to kill viruses, bacteria and germs. Particular preference is given to catalysts based on titanium dioxide due to the high efficiency and biocompatibility of this material.

Beispielsweise kann als Fotokatalysator das Produkt "Titan Shield®" eingesetzt werden.For example, the product "Titan Shield ®" can be used as a photocatalyst.

Denkbar ist ein Abbau von Geruchsstoffen auch mittels Oxidation, z.B. durch Zugabe von Ozon oder durch UV-Bestrahlung.It is also conceivable degradation of odorous substances by means of oxidation, e.g. by adding ozone or by UV irradiation.

Aufhängemittel:suspension:

Um die Wäsche im Nutzraum 1 aufzuhängen, sind Aufhängemittel 26 vorgesehen. Diese können z.B. eine Aufhängung in Form einer Kleiderstange 28 umfassen, sowie geeignete Kleiderbügel, Klammern oder dergleichen.To hang the laundry in the utility room 1, suspension means 26 are provided. These may e.g. a suspension in the form of a clothes rod 28 include, as well as appropriate hangers, brackets or the like.

Bemerkungen:Remarks:

Der hier beschriebene Schranktrockner kann zum Trocknen oder auch zum Aufbereiten von Wäsche verwendet werden. Unter "Aufbereiten" ist dabei nicht notwendigerweise ein Wasserentzug zu verstehen, sondern z.B. auch eine Hygienisierung und/oder Entknitterung (z.B. mittels Dampf bzw. UV- oder Ozongenerator und Photokatalyse) oder die Neutralisierung von Gerüchen (z.B. mit Hilfe der erwähnten Mitteln zum Beimischen von Enzymen oder mit dem UV- bzw. Ozongenerator und Photokatalyse).The cabinet dryer described here can be used for drying or for the treatment of laundry. By "processing" is not necessarily meant a dehydration, but e.g. also sanitizing and / or wrinkling (for example by means of steam or UV or ozone generator and photocatalysis) or the neutralization of odors (for example with the aid of the mentioned agents for mixing in enzymes or with the UV or ozone generator and photocatalysis).

Die vorliegende Erfindung kann besonders vorteilhaft in einem Schranktrockner eingesetzt werden, da in solchen Schranktrocknern mit Vorteil Prozessphasen vorkommen, bei denen die Kühl- und die Heizvorrichtung 7 bzw. 8 nicht benötigt werden, z.B. die oben erwähnte Phase, bei welcher eine erhöhte Luftmenge durch den Schrank geführt wird, um die Wäsche zum Flattern zu bringen, oder wenn die Prozessluft mit Dampf, Ozon, UV-Licht oder Duftstoff behandelt werden soll.The present invention can be used particularly advantageously in a cabinet dryer, since in such cabinet dryers advantageously process phases occur in which the cooling and heating devices 7 and 8 are not required, e.g. the above-mentioned phase, in which an increased amount of air is passed through the cabinet to make the laundry flutter, or when the process air is to be treated with steam, ozone, UV light or perfume.

Die vorliegende Technik kann jedoch auch in anderen Wäschetrocknern eingesetzt werden, insbesondere in Trommelwäschetrocknern. Auch dort kann mindestens ein Teil der Prozessluft dank dem zweiten Kanal 32 um die Kühl- und Heizvorrichtung herum geführt werden, z.B. während einer Dampfbehandlung der Wäsche.However, the present technique can also be used in other clothes dryers, especially in tumble dryers. Also there, at least a portion of the process air thanks to the second channel 32 to the Cooling and heating device are guided around, for example during a steam treatment of the laundry.

Zusammenfassend sind in einem Wäschetrockner, insbesondere einem Trockenschrank, also eine Kühlvorrichtung und eine Heizvorrichtung vorgesehen, durch welche die Prozessluft zwecks Entfeuchtung geführt werden kann. Die Kühl- und die Heizvorrichtung sind in einem ersten Kanal angeordnet. Parallel zum ersten Kanal ist ein zweiter Kanal vorgesehen, durch den Prozessluft an der Kühl- und Heizvorrichtung vorbei geführt werden kann.
