Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1 sowie ein Verfahren nach dem Oberbegriff des Patentanspruches 5 und ein Gerät zur Durchführung des Verfahrens nach dem Oberbegriff des Patentanspruches 7.The present invention relates to a method according to the preamble of claim 1 and a method according to the preamble of claim 5 and a device for performing the method according to the preamble of claim 7.
Bekanntlich enthalten Gewebe, Kleidungsstücke, Lederbekleidung und Schuhe Restbestandteile von z.B. Pestiziden und anderen Chemikalien, die bei der Erzeugung der Fasern, z.B. der Baumwolle, beim Gerben von Leder, beim Färben und bei der Ausrüstung eingesetzt werden. Diese Chemikalien können die Haut empfindlicher oder allergischer Personen beim Tragen insbesondere von neuen Kleidungsstücken reizen und zu unangenehmen Reaktionen führen. Aus diesem Grunde wird das Waschen neuer Kleidungsstücke vor dem Tragen empfohlen, wodurch jedoch die Chemikalien nicht immer vollständig beseitigt werden. Nach Versuchen ist ein bis zu zehnmaliges Waschen hierfür erforderlich, um die Schadstoffe völlig zu entfernen.It is known that fabrics, clothing, leather clothing and shoes contain residual components of e.g. Pesticides and other chemicals used in the production of the fibers e.g. cotton, tanning leather, dyeing and finishing. These chemicals can irritate the skin of sensitive or allergic people, especially when wearing new clothing, and lead to unpleasant reactions. For this reason, washing new garments before wearing them is recommended, but this does not always completely remove the chemicals. After trials, washing up to ten times is necessary to completely remove the pollutants.
Auch ist das Sterilisieren von Kleidungsstücken ein Problem, weil weder mit Waschen in bekannten Waschmaschinen noch durch Trommeltrockner eine Sterilisation erreichbar ist. Aus der DE-PS 33 43 236 ist ein Verfahren zum Trocknen und Sterilisieren, insbesondere von empfindlichen Geweben, bekannt, wobei sowohl die Trocknung als auch die Sterilisation der Gewebe im gleichen Behandlungsraum in hängendem, im wesentlichen unbewegtem Zustand durchgeführt und die Sterilisation unmittelbar im Anschluß an die Trocknung vorgenommen wird, wobei die Gewebe zuerst unter Verwendung eines Warmluftstromes in bekannter Weise getrocknet und anschließend die Sterilisation in einem Heißluftstrom vorgenommen wird.The sterilization of clothing is also a problem because sterilization cannot be achieved either with washing in known washing machines or with a tumble dryer is. From DE-PS 33 43 236 a method for drying and sterilizing, in particular sensitive tissues, is known, wherein both the drying and the sterilization of the tissues are carried out in the same treatment room in a hanging, essentially unmoving state and the sterilization immediately afterwards drying is carried out, the tissue first being dried in a known manner using a warm air stream and then the sterilization being carried out in a hot air stream.
Die Vorrichtung zur Durchführung des Verfahrens nach DE-PS 33 43 236 umfaßt einen Trockenschrank mit Einrichtungen zum Einhängen von Gewebeteilen und mit Mitteln zur Erzeugung, Verteilung und insbesondere Kreislaufführung von Warmluft und von Heißluft, die ein Gebläse und ein Heizaggregat aufweisen, wobei das Gebläse eine an sich bekannte Einrichtung zur Einstellung der Menge des Förderluftstromes mit einer Drehzahlumschalteinrichtung in wenigstens zwei Stufen und der Trockenschrank einen das Heizregister an- und abschaltbar steuernden Überhitzungsschalter aufweist.The device for performing the method according to DE-PS 33 43 236 comprises a drying cabinet with devices for hanging tissue parts and with means for generating, distributing and in particular circulating hot air and hot air, which have a blower and a heating unit, the blower being a Known device for adjusting the amount of the conveying air flow with a speed changeover device in at least two stages and the drying cabinet has an overheating switch which controls the heating register and can be switched off.
Wenn sich auch das bekannte Verfahren und die zugehörige Vorrichtung in der Praxis durchaus bewährt haben, hat sich doch nachteilig gezeigt, daß eine vollständige Entgiftung der Gewebeteile nicht durchführbar ist.Although the known method and the associated device have proven their worth in practice, it has been shown disadvantageously that complete detoxification of the tissue parts cannot be carried out.
Deswegen ist es eine Aufgabe der vorliegenden Erfindung, das bekannte Verfahren und die bekannte Vorrichtung derart weiterzuentwickeln, daß bei Erhaltung der Eigenschaften Lüften, Trocknen und Sterilisieren insbesondere das vollständige Entgiften durchführbar ist.It is therefore an object of the present invention to further develop the known method and the known device in such a way that, while maintaining the properties of ventilation, drying and sterilization, in particular complete detoxification can be carried out.
Die Lösung der Aufgabe erfolgt mit einem Verfahren nach den Merkmalen des Patentanspruches 1.The problem is solved with a method according to the features of claim 1.
Dadurch, daß der durch die Lufteintrittsöffnung eintretende Luftstrom nach Durchströmen des ersten Zwischenraumes durch eine Heizvorrichtung erwärmt wird, daß der erwärmte Luftstrom von zwei einander gegenüberliegenden Seiten in den Innenraum geführt wird und daß der aus dem Innenraum austretende Luftstrom von einem Gebläse angesogen und durch eine Luftaustrittsöffnung nach außen gedrückt wird, ist eine sehr wirkungsvolle Luftführung erreichbar, die eine praktisch vollständige Entgiftung durch Ausblasen der an den textilen Geweben anhängenden Bestandteile erzielt. Auch die von den Öffnungen entfernt liegenden zu trocknenden Gutstücke, d.h. diejenigen in der Mitte des Innenraumes, werden auf kurzen Strömungswegen von den Luftströmen erreicht. Außerdem entstehen durch das frontale Aufeinanderprallen der Luftströme von zwei Seiten Luftturbulenzen, die die Durchlüftungs- und Entgiftungswirkung verstärken.Characterized in that the air stream entering through the air inlet opening is heated by a heating device after flowing through the first intermediate space, that the heated air stream is guided into the interior from two opposite sides and that the air stream emerging from the interior is drawn in by a blower and through an air outlet opening is pressed outwards, a very effective air flow can be achieved, which achieves a practically complete detoxification by blowing out the components attached to the textile fabrics. The items to be dried that are located away from the openings, i.e. those in the middle of the interior are reached by the air currents on short flow paths. In addition, the frontal collision of the air flows from two sides creates air turbulence, which increases the ventilation and detoxification effect.
Zur weiteren Optimierung der Führung des Luftstroms ist vorgesehen, daß der erwärmte Luftstrom durch einen zweiten Zwischenraum geführt wird, der durch die nach innen weisende Wand des ersten Zwischenraumes und die Wand des Innenraumes gebildet ist, und daß der erwärmte Luftstrom durch eine Vielzahl von Öffnungen in der nach innen weisenden, den Innenraum umgrenzenden Wand des zweiten Zwischenraumes in den Innenraum geführt wird.To further optimize the guidance of the air flow, it is provided that the heated air flow is passed through a second intermediate space, which is formed by the inward-facing wall of the first intermediate space and the wall of the interior, and that the heated air flow is passed through a plurality of openings in the inward-facing wall of the second intermediate space delimiting the inner space is guided into the inner space.
In einer vorteilhaften Ausgestaltung insbesondere zum Trocknen textiler Kleidungsstücke wird der aus dem Innenraum austretende Luftstrom über einen Kondensator geführt und danach von dem Gebläse angesogen. Der Kondensator wirkt dabei in an sich bekannter Weise als Kühlfalle, d.h. die feuchte Luft wird an den Kondensatorwänden bis zur Unterschreitung des Taupunktes abgekühlt, wobei das abgeschiedene Wasser in einer Tropfschale gesammelt wird.In an advantageous embodiment, in particular for drying textile items of clothing, the air stream emerging from the interior is guided over a condenser and then sucked in by the blower. The condenser acts in a manner known per se as a cold trap, ie the moist air is cooled on the condenser walls until the dew point is undershot, the separated water being collected in a drip tray.
Zur Unterstützung des Trocknungsvorganges ist es zweckmäßig, daß der von dem Gebläse angesogene Luftstrom durch den zweiten Zwischenraum derart in den Innenraum gedrückt wird, daß der Luftstrom in einem geschlossenen Kreislauf bewegt wird. Der Trocknungsvorgang ist dabei in an sich bekannter Weise durch einen Feuchtigkeitssensor überwachbar.To support the drying process, it is expedient that the air flow sucked in by the blower is pressed into the interior through the second intermediate space in such a way that the air flow is moved in a closed circuit. The drying process can be monitored in a manner known per se by a moisture sensor.
Ist in bestimmten Anwendungsfällen ein Verfahren gefordert, wobei eine vorhandene Heizvorrichtung nicht eingeschaltet wird, wird dieses besonders wirkungsvoll in einem Verfahren nach den Merkmalen des Patentanspruches 5 ausgeführt.If a method is required in certain applications and an existing heating device is not switched on, this is carried out particularly effectively in a method according to the features of claim 5.
Dadurch, daß der durch die Lufteintrittsöffnung eintretende Luftstrom als Kühlmittel durch einen Kondensator geführt wird, daß der aus dem Kondensator austretende Luftstrom von dem Gebläse angesogen und in den Innenraum gedrückt wird und daß der aus dem Innenraum austretende Luftstrom von einem zweiten Gebläse angesogen und durch die Luftaustrittsöffnung gedrückt wird, wird durch das zusammenwirkende Saugen und Drücken der beiden Gebläse eine besonders wirksame Luftströmung erzeugt.Characterized in that the air stream entering through the air inlet opening is passed as a coolant through a condenser, that the air stream emerging from the condenser is drawn in by the fan and pressed into the interior and that the air stream emerging from the interior is drawn in by a second fan and through the Air outlet opening is pressed, a particularly effective air flow is generated by the interacting suction and pressing of the two fans.
Zur Unterstützung der Durchwirbelung der Luftströmung ist vorteilhaft vorgesehen, daß der Luftstrom durch periodisches Ein- und Ausschalten des Gebläses oder periodische Drehzahländerung unstetig bewegt wird.To support the swirling of the air flow, it is advantageously provided that the air flow is moved continuously by periodically switching the fan on and off or by periodically changing the speed.
Das erfindungsgemäße Verfahren nach den Ansprüchen 1 bis 4 und 6 wird vorteilhaft in einem Gerät gemäß Anspruch 7 durchgeführt.The inventive method according to claims 1 to 4 and 6 is advantageously carried out in a device according to claim 7.
Dadurch, daß der erste Zwischenraum mindestens eine im oberen Bereich des Trockenschrankes eingeformte Lufteintrittsöffnung aufweist, daß die Heizvorrichtung, das Gebläse und fallweise zusätzlich der Kondensator im Bereich unterhalb des Innenraumes angeordnet sind und daß die Öffnungen in zwei einander gegenüberliegenden Wänden des Innenraumes vorgesehen sind, ergibt sich eine weitgehende Staubfreiheit der nicht in Bodennähe angesaugten Luft und eine gute Stabilität des Gerätes durch eine tiefe Schwerpunktlage. Außerdem wird so die für das Verfahren günstige Luftströmung mit von zwei Seiten her aufeinander zu strömenden Luftströmen sichergestellt.Characterized in that the first intermediate space has at least one air inlet opening formed in the upper region of the drying cabinet, that the heating device, the blower and in some cases additionally the condenser in the region are arranged below the interior and that the openings are provided in two opposite walls of the interior, there is a largely dust-free air not drawn in near the floor and good stability of the device due to a low center of gravity. In addition, the air flow which is favorable for the method is ensured with air flows flowing towards one another from two sides.
Zur Durchführung des Verfahrens auch nach Anspruch 5 ist vorgesehen, daß der Kondensator durch einen mit einem zweiten Gebläse erzeugbare Luftstrom kühlbar ist. Dadurch wird in besonders eleganter Weise nur ein Luftstrom benötigt, der vor seiner Erwärmung den Kondensator als Kühlmittel durchströmt.To carry out the method according to claim 5 it is provided that the condenser can be cooled by an air flow which can be generated by a second fan. As a result, only an air flow is required in a particularly elegant manner, which flows through the condenser as a coolant before it is heated.
Zur Unterstützung der Sterilisierung kann der Trockenschrank, wie an sich bekannt, eine Einrichtung zum Einsprühen einer bakteriziden Flüssigkeit und fallweise zusätzlich eine Ozonerzeugungskammer aufweisen.To support the sterilization, the drying cabinet, as is known per se, can have a device for spraying in a bactericidal liquid and, in some cases, an additional ozone generation chamber.
