Description

Beschreibung Geschirrspülmaschine Die Erfindung betrifft eine Geschirrspülmaschine mit einem Spülbehälter und Vorrichtungen zum Spülen von Geschirr mittels Spülflotte.Eine Geschirrspülmaschine weist bekanntlich ein Spülverfahren auf, dessen Proim Algemeinen aus wenigstens ei- Teilprogrammmschritt "Vorspülen", einem Teü"Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilpro"Trocknen" besteht. Zur Erhöhung des Reinigungseffekts wird dabei die Spülflüssigkeit vor oder während eines Teilprogrammschrittes erwärmt. Die Erwärmung der Spülflüssigkeit erfolgt üblicherweise mittels elektrischer Heizungen im Spüler und/ oder durch Zuleitung warmen Wassers aus der Hausinstallation. Zur Trocknung von Spülgut in einer Geschirrspülmaschine sind unterschiedliche Trocknungssysteme bekannt. Beispielsweise kann das Spülgut durch Eigenwärmetrocknung getrocknet werden, wenn die Spülflüssigkeit im Teilprogrammschritt "Klarspülen" erwärmt wird und somit das heiß klargespülte Spülgut durch den so aufgebauten materialabhängigen Wärmeinhalt des Spülguts während des Teilpro' rocknen" von selbst trocknet. Um diese Eigenwärmetrocknung zu erreichen, wird die Spülflüssigkeit im Teilprogrammschritt "Klarspülen" mit einer gesonderten Heizung auf eine bestimmte Temperatur erwärmt und über in der Geschirrspülmaschine vorhandene Sprüheinrichtungen auf das Spülgut aufgebracht. Durch die relativ hohe Temperatur der Spül- flüssigkeit im Teilprogrammschritt "Klarspülen" von üblicherweise von 55°C bis 75°C wird erreicht, dass eine hinreichend große Wärmemenge auf das Spülgut übertragen wird, so dass das am Spülgut anhaftende Restwasser durch die im Spülgut gespeicherte Wärme verdampft. Der Dampf kondensiert an kälteren Flächen oder wird mittels Gebläse aus dem Geschirrspüler ausgetragen. Bei einer weiteren bekannten Trocknungseinrichtung wird eine separate Heizquelle, z.B. ein Heißluftgebläse, im Spülbehälter dazu verwendet, das feuchte Luftgemisch beim Trocknungsvorgang zu erwärmen, damit die Luft im Spülbehälter eine größere Menge an Feuchtigkeit aufnehmen kann. Ein Nachteil bei den oben beschriebenen Heizungssysteme nach dem beschriebenen Stand der Technik besteht darin, dass die Erwärmung der Spül- flüssigkeit mit einem relativ hohen Energiebedarf verbunden ist und die benötigte Wärmeenergie für jede Erwärmungsphase mittels der elektrischen Heizelemente neu erzeugt werden muss. Ebenso haben die bekannten Heizungssysteme den Nachteil, dass die Erwärmung der Spülflüssigkeit im Teilprogrammschritt "Klarspülen" sowie die Vorgänge im Teilpro'Trocknen" selbst mit einem hohen Energiebedarf verbunden sind und die benötigte Wärmeenergie nach dem Trocknungsvorgang verloren geht, weil diese in die Umgebung entweichen.Es sind Geschirrspülmaschinen bekannt, bei denen die Feuchtluft nach außen abgelassen wird. Dies ist nachteilig, da die umgebenden Küchenmöbel geschädigt werden und das Verfahren eine eventuell unhygienische Luftzufuhr in den Geschirrspüler von außen erfordert. Des Weiteren sind Geschirrspülmaschinen bekannt, bei denen vor dem Ausleiten die Feuchtluft über Kondensationsflächen geleitet wird, an denen die Feuchtigkeit kondensiert. Dieses Kondenswasser wird entweder in den Spülbehälter oder in spezielle Auffangbehälter geleitet. Aus der DE 30 21 746 AI ist ein Verfahren zum Betreiben einer Geschirrspülmaschine bekannt, bei dem ein wärmeleitend mit dem Spülbehälter verbundener Wärmetauscher während eines Teilprogrammschrittes „Trocknen" mit kaltem Frischwasser gespeist wird. Dadurch wird eine Kondensationsfläche auf der Innenseite des Spülbehälters erzeugt, an der die Feuchtigkeit kondensiert und das entstehende Kondenswasser im Spülbehälter verbleibt. Da der Temperaturunterschied zwischen der Feuchtluft und dem eingefüllten Frischwasser relativ gering ist und die Frischwassermenge sich stetig erwärmt, ergibt sich der Nachteil, dass die Kondensation der Feuchtluft lange dauert und die Kondensationsleistung stetig geringer wird und die Dauer des Teilprogrammschrittes „Trocknen" lang ist, bei mäßigem Trocknungsergebnis. Mit der Dauer des Trocknungsvorganges werden durch die feuchtwarme Umgebung die stets vorhandenen Keime auf dem Spülgut zum schnellen Wachstum angeregt. Aufgabe der vorliegenden Erfindung ist es daher, eine Geschirrspülmaschine bereitzustellen, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effektiv und effizient zu trocknen und somit den Energieaufwand trotz sehr guter Trocknungsleistung so gering wie möglich zu halten.Diese Aufgabe wird durch die erfindungsgemäße Geschirrspülmaschine mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen ge- kennzeichnet.Die erfindungsgemäße Geschirrspülmaschine mit einem Spülbehäler und Vorrichtungen zum Spülen von Geschirr mittels Spülflotte weist einen Behälter mit einem verdampfbaren und/oder sublimierbaren Medium und einen Sorber mit reversibel dehydrierbaren Material auf, wobei zwischen Behälter und Sorber ein Gasaustausch möglich ist und der Sorber einerseits mittelbar zur Trocknung des Geschirrs verwendet wird und andererseits die zur Desorption des Sorbers eingesetzte Wä- meenergie zur Erwärmung der im Spülbehälter befindlichen Spülflotte und/oder des Geschirrs wenigstens teilweise verwendet wird.In einer bevorzugten Ausführungsform sind der Behälter und der Sorber vorzugsweise verschließbar mit einem Ventil über eine Austauschleitung zum Gasaustausch miteinander verbunden. Mittels des Ventils kann vorteilhafterweise die Verbindung zwischen dem Behälter und Sorber gezielt unterbrochen werden, um die Aufnahme des Mediums durch den Sorber zu steuern.Vorzugsweise ist mit einem Gebläse Luft durch einen Auslass aus dem Spülbehälter in Leitungen und wieder zurück in den Spülbehälter durch einen Einlass leitbar. In einer weiteren Ausführungsform ist in Strömungsrichtung der Luft an den Leitungen zuerst der Behälter und dann der Sorber angeordnet, um einen Wärmeaustausch zwischen der strömenden Luft in den Leitungen und dem Medium im Behälter sowie dem reversibel dehydrierbaren Material im Sorber zu ermöglichen.In einer ergänzenden Ausführungsform ist zur Desorption des reversibel dehydrierbaren Materials im Sorber ein elektrisches Heizelement angeordnet. Das elektrische Heizelement ermöglicht vorteilhafterweise die gezielete Desorption des im Sorber enthaltenen reversibel dehydrierbaren Materials durch Erhitzen. Vorzugsweise ist bei ausgeschaltetem elektrischen Heizelement und geöffnetem Ventil das Medium, z. B. Wasser, im Behälter, verdampfbar oder sublimierbar und durch die Verdunstungskälte der Behälter mit Medium abkühbar, der Mediumdampf über die Austauschleitung zum Sorber leitbar und der Mediumdampf vom reversiblen dehydrierbaren Material im Sorber auf ehmbar, wodurch der Sorber mit reversibel dehydrierbarem Material erwärmbar ist. Damit wird vorteilhafterweise der Behälter gekühlt und der Sorber erwärmt, so dass damit einerseits Luft durch Abkühlen entfeuchtet werden kann und andererseits Luft erwärmt werden kann, so dass das Feuchtigkeitsaufnahmevermögen der Luft ansteigtJn einer weiteren Ausführungsform ist bei eingeschaltetem elektrischem Heizelement zur Desorption des Sorbers der Sorber erwärmbar und bei geöffnetem Ventil das im Sorber gebundene Medium verdampfbar, der im Sorber freigesetzte Mediumdämpf über die Austauschleitung zum Behälter leitbar und der Mediumdampf im Behälter kondensierbar, wodurch der Behälter mit Medium aufgrund der Verdunstungswäme erwärmbar ist. Das im Sorber aufgenommene Medium kann damit vorteilhafterweise im Sinne eines geschlossenen Kreislaufes wieder in den Behälter zurückgeführt werden.The invention relates to a dishwasher with a rinsing container and devices for rinsing crockery by means of rinsing liquor. A dishwasher is known to have a rinsing process whose profile generally consists of at least one partial program step "pre-rinsing", one "cleaning", at least one partial program step "intermediate rinsing ", a sub-program step" rinse "and a Teilpro" drying "consists. To increase the cleaning effect while the rinsing liquid is heated before or during a Teilprogrammschrittes. The heating of the rinsing liquid is usually carried out by means of electrical heaters in the dishwasher and / or by supplying hot water from the house installation. For drying items to be washed in a dishwasher different drying systems are known. For example, the items to be washed can be dried by self-heat drying if the rinsing liquid is heated in the partial program step "rinsing" and thus the hot, rinsed items are automatically dried by the material-dependent heat content of the items to be rinsed during the partial drying Due to the relatively high temperature of the rinsing liquid in the subprogram step "rinsing" of usually from 55 ° C to 75 ° C., the rinsing liquid is heated to a specific temperature by means of a separate heating in the subprogram step "rinsing" ° C ensures that a sufficiently large amount of heat is transferred to the items to be washed, so that the residual water adhering to the items to be washed evaporates due to the heat stored in the items to be washed.The steam condenses on colder surfaces or is blown out In a further known drying device, a separate heat source, eg a hot air blower, is used in the washing container to heat the moist air mixture during the drying process, so that the air in the washing container can absorb a larger amount of moisture. A drawback with the prior art heating systems described above is that the heating of the rinsing liquid is associated with a relatively high energy requirement and the required heat energy must be regenerated for each heating phase by means of the electrical heating elements. Likewise, the known heating systems have the disadvantage that the heating of the rinsing liquid in the program step "rinsing" and the operations in Teilpro'Trocknen "are themselves associated with high energy requirements and the required heat energy is lost after the drying process, because they escape into the environment. Dishwashers are known in the art where the moist air is discharged to the outside. This is disadvantageous because the surrounding kitchen furniture is damaged and the process requires a possibly unhygienic air intake into the dishwasher from the outside. Furthermore, dishwashers are known in which, before discharging the moist air is passed through condensation surfaces on which the moisture condenses. This condensation water is directed either into the rinsing container or into special collection containers. DE 30 21 746 A1 discloses a method for operating a dishwasher, in which a heat exchanger connected to the washing container during a partial program step "drying" is fed with cold fresh water Since the temperature difference between the moist air and the filled fresh water is relatively low and the amount of fresh water is constantly heated, there is the disadvantage that the condensation of the moist air takes a long time and the condensation power is steadily lower and the duration of the partial program step "drying" is long, with moderate drying result. With the duration of the drying process, the ever-present germs on the dishes are stimulated by the humid-warm environment for rapid growth. The object of the present invention is therefore to provide a dishwasher, with which it is possible to effectively and efficiently dry the items located in the washing container from an economic point of view and thus to keep the energy expenditure as low as possible despite very good drying performance the dishwasher according to the invention with the features of claim 1 solved. Advantageous developments of the present invention are characterized in the subclaims. The dishwasher according to the invention with a rinsing container and devices for rinsing dishes by means of rinsing liquor has a container with a vaporizable and / or sublimable medium and a sorber with reversibly dehydratable material, wherein between container and Sorber a gas exchange is possible and the sorber is used on the one hand indirectly for drying the dishes and on the other hand, the heat energy used for desorption of the sorber for heating the rinsing in the rinse tank and / or the dishes is at least partially used. In a preferred embodiment the container and the sorber are preferably closably connected to each other with a valve via an exchange line for gas exchange. By means of the valve can advantageously be selectively interrupted the connection between the container and sorber to control the recording of the medium through the sorber. Preferably, with a fan air through an outlet from the Rinsing container in lines and back into the washing container through an inlet conductive. In a further embodiment, in the flow direction of the air to the lines first the container and then the sorber is arranged to allow a heat exchange between the flowing air in the lines and the medium in the container and the reversibly dehydratable material in the sorber. In a supplementary embodiment For the desorption of the reversibly dehydratable material in the sorber an electric heating element is arranged. The electrical heating element advantageously enables the targeted desorption of the reversibly dehydratable material contained in the sorber by heating. Preferably, when the electric heating element and the valve is open, the medium, for. As water in the container, evaporable or sublimable and abkühbar by the evaporative cooling of the container with medium, the medium vapor via the exchange line to the sorber and the medium vapor from the reversible dehydratable material in the sorber on ehmbar, whereby the sorber can be heated with reversible dehydratable material. Thus, the container is advantageously cooled and the sorber is heated so that on the one hand air can be cooled by cooling and on the other hand air can be heated, so that the moisture absorption capacity of the air increases. In another embodiment, the sorber can be heated when the electric heating element is desorbed and with the valve open, the medium bound in the sorber vaporizable, the medium vapor released in the sorber via the exchange line to the container and the condensable medium vapor in the container, whereby the container with medium due to the evaporation heat can be heated. The medium absorbed in the sorber can thus advantageously be returned to the container in the sense of a closed circuit.
[002] In einer zusätzlichen Ausführungsform ist während eines Teilprogrammschrittes "Trocknen" Luft aus dem Spülbehälter durch die Leitungen und wieder zurück in den Spülbehälter leitbar, wobei die Luft am Behälter kühlbar und dadurch die in der Luft enthaltene Feuchtigkeit wenigstens teilweise kondensierbar ist sowie am Sorber die Luft erwärmbar ist, um das Feuchtigkeitsaufnahmevermögen der Luft zu erhöhen. Die im Kreislauf umgewälzte Luft des Spülbehälters wird damit vorteilhafterweise einerseits entfeuchtet und andererseits erwärmt, so dass trockene und warme Luft in den Spülbehälter zum Trocknen des Geschirrs eingeleitet werden kann.In an additional embodiment, during a partial program step "drying" air from the washing container through the lines and back into the washing container can be conducted, the air on the container can be cooled and thereby the moisture contained in the air is at least partially condensable and the sorber the air is heated to increase the moisture absorption capacity of the air. The air circulated in the circulation of the washing container is thus advantageously dehumidified on the one hand and on the other hand heated, so that dry and warm air can be introduced into the washing container for drying the dishes.
[003] Vorzugsweise ist während eines Teilprograrnmschrittes mit zu erwärmender Spül- flüssigkeit, z. B. "Reinigen" oder "Vorspülen", Luft aus dem Spülbehälter durch die Leitungen und wieder zurück in den Spülbehälter leitbar, wobei die Luft am Behälter vorzugsweise erwärmbar ist und am Sorber erwärmbar ist. Dies ermöglicht in besonders vorteilhafter Weise die Verwendung der zur Desorption eingesetzten War- meenergie zum Erwärmen der Spülflotte und/oder des Geschirrs.[003] Preferably, during a partial program step with rinsing liquid to be heated, eg.

This makes it possible in a particularly advantageous manner to use the warning used for desorption. meenergie for heating the rinse liquor and / or the dishes.
[004] Zweckmäßigerweise ist das am Behälter in der Leitung durch Kondensation aus der in der Leitung durchströmenden Luft entstehende Wasser in den Spülbehälter oder in einen gesonderten Behälter leitbar. Das entstehende Kondenswasser kann damit einfach abgeleitet werden.Conveniently, the resulting water on the container in the line by condensation from the air flowing through the line water in the washing or in a separate container can be conducted. The resulting condensation can be easily derived.

Am Ende der Leitung 6 befindet sich in der Leitung 6 ein Behälter 12, der mit Wasser 16 oder Eis gefüllt ist. Dadurch ist ein Wärmeaustausch zwischen der Luft in der Leitung 6 und dem Wasser 16 oder Eis im Behälter 12 möglich ist. In der Leitung 9 ist durch den' Sorber 10 angeordnet, in dem sich reversibel dehydrierbares Material 11, z. B. Zeolith, befindet. Im Sorber 10 ist ein elektrisches Heizelement 17 vorhanden, welche das reversibel dehydrierbare Material 11 bei Bedarf zur Desorption erhitzt. Der Sorber 10 und der Behälter 12 sind über eine Austauschleitung 15 miteinander verbunden, wobei in der Austauschleitung 15 ein Ventil 14 angeordnet ist, um die Verbindung zwischen dem Behälter 12 und dem Sorber 10 unterbrechen zu können.According to the invention, the dishwasher 1 has a closed air circuit, which leads through the lines 6, 7 and 9 and the washing compartment 2 with crockery baskets 3, 4. In the washing compartment 2 is located in dish racks 3, 4, the dishes. The dishes in the baskets 3, 4 is not shown. In the upper region of the washing container 2 is an outlet 5 from the washing container 2, in which the air flows into the conduit 6, see arrow A. In the lower part of the washing compartment 2 there is an inlet 8, in which the air from the line. 9 flows into the washing container 2 see arrow C. Between the line 6 and 9, the line 7 is arranged with the blower 13, which promotes the air in the line 7 in the flow direction according to arrow B. At the end of the line 6 is located in the conduit 6, a container 12 which is filled with water 16 or ice. As a result, a heat exchange between the air in the conduit 6 and the water 16 or ice in the container 12 is possible. In the conduit 9 is arranged by the ' sorber 10, in which reversibly dehydratable material 11, z. As zeolite, is located. In the sorber 10 there is an electric heating element 17, which heats the reversibly dehydratable material 11 for desorption if necessary. The sorber 10 and the container 12 are connected to each other via an exchange line 15, wherein in the exchange line 15, a valve 14 is arranged to interrupt the connection between the container 12 and the sorber 10 can.
[009] Bei dem geschlossenen Luftsystem ist ein Austausch von verschmutzter Luft aus der Umgebung ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes verhindert wird. Eine Geschirrspülmaschine weist bekanntlich ein Spülverfahren auf dessen Proim Allgemeinen aus wenigstens eiTeilprogrammschritt "Vorspülen", einem Teil"Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilpro'Trocknen" besteht.Erfindungsgemäß wird in einem Teilprogrammschritt "Trocknen" mit Hilfe des Gebläses 13 Luft aus dem Spülbehälter 2 über den Einlass 5 durch die Leitungen 6, 7 und 9 und wieder zurück über den Einlass 8 in den Spülbehälter 2 geleitet. Im Teilprogrammschritt "Trocknen" befindet sich im Spülbehälter 2 nasses, zu trocknendes Geschirr mit feuchter Luft. Das Ventil 14 in der Austauschleitung 15 ist vorzugsweise geöffnet. Das im Sorber 10 enthaltene reversibel dehydrierbare Material 11 hat eine verhältnismäßig große Kapazität zur FeuchtigkeitsWird nun der Behälter 12 mit der Sorptionskolonne 10 verbunden durch Öffnen des Ventils 14, nimmt das reversibel dehydrierbare Material 11 in kurzer Zeit eine große Menge des in dem Behälter 12 enthaltenen Wassers 16 auf und der in dem Behälter 12 verbliebene Rest von Wasser wird durch Verdunstungskälte stark abgekühlt, z. B. bis es gefriert. Das Wasser 16 oder Eis im Behälter 12 verdunstet oder sublimiert und der Wasserdampf gelangt über die Austauschleitung 15 zum Sorber 10. Im Sorber 10 wird der Wasserdampf vom reversibel dehydrierbaren Material 11 aufgenommen. Durch die dabei auftretende Kondensationswärme erwärmt sich das reversibel dehydrierbare Material 11 und damit der Sorber 10. Durch das Abkühlen des Behälters 12 wird ein sehr großer Temperaturunterschied zwischen der Feuchtluft und der Kondensationsfläche, die an der Innenseite der Leitung 6 entsteht, erzeugt. Die aus dem Spülbehälter 2 geleitete feuchte Luft kondensiert dadurch. Das dabei frei werdende Kondenswasser muss abgeleitet werden, z. B. in den Spülbehälter 2 oder in einen gesonderten Vorratsbehälter (nicht dargestellt). Die am Behälter 12 abgekühlte und entfeuchtete Luft wird über die Leitung 7 weiter zum Sorber 10 geleitet. Der Sorber 10 weist eine stark erhöhte Temperatur, z. B. 90°, aufgrund der auftretenden Kondensationswäreme auf. Dies führt zum Erwärmen der durchgeleiteten Luft in der Leitung 9, wodurch die relative Luftfeuchtigkeit' noch weiter abnimmt und das Fechtigkeitsaufnahmevermögen der Luft stark zunimmt. Diese trockene und warme Luft wird in den Spülbehälter 2 über den Einlass 8 eingeleitet und kann hier das zu trocknende Geschirr sowohl erwärmen als auch trocknen. Die über den Einlass 8 eingeleitete Luft nimmt im Spülraum 2 Feuchtigkeit auf und kühlt ab und wird anschließend in einem geschlossenem Kreislauf wieder über den Auslass 5 in die Leitung 6 eingeleitet. Vorzugsweise erfolgt das Öffnen des Ventils 14 während des Teilprogrammschrittes „Trocknen", so dass das Abkühlen des Behälters 12, das Erwärmen des Sorbers 10 und das Umwälzen der Luft durch die Leitungen 6, 7 und 9 simultan erfolgt. Es kann jedoch auch bereits vor Beginn des Umwälzens der Luft das Ventil 14 geöffnet werden, so dass bereits zu Beginn des Umwälzens der Luft zum Trocknen der Behälter 12 entsprechend abgekühlt und der Sorber 10 erwärmt ist und damit die volle Trocknungsleistung von Anfang an zur Verfügung steht. Des Weiteren kann das Ventil auch während des Umwälzens der Luft wenigstens teilweise geschlossen sein, weil aufgrund des Wärme- und Kältespeichervermögens des Behälters 12 und des Sorbers 10 keine zusätzliche Kühlung oder Erwärmung erforderlich ist. Während anderer Teilprogrammschritte, die keine Trocknung erfordern, bleibt das Ventil 14 normalerweise geschlossen, weil dadurch eine unnötige Erwärmung oder Abkühlung des Behälters 12 oder Sorbers 10 erreicht würde.Das reversibel dehydrierbare Material 11 im Sorber 10 muss zur Desorption auf sehr hohe Temperaturen erhitzt werden, was mit dem elektrischen Heizelement 17 bewerkstelligt wird. Dabei tritt die gespeicherte Flüssigkeit als heißer Wasserdampf aus, der über die Austauschleitung 15 bei geöffnetem Ventil 14 zum Behälter 12 gelangt, welcher als Verflüssiger fungiert, weil der heiße Wasserdampf im Behälter 12 kondensiert. Durch die Kondensationswärme wird der Behälter 12 und das Wasser 16 erwärmt. Der Sorber 10 wird vom elektrischen Heizelement auf hohe Temperaturen, z. B. 150° - 200°, erhitzt. Erfindungsgemäß wird die zur Desorption eingesetzte Wämeenergie wenigstens teilweise zur Erwärmung der Spülflotte und oder des Geschirrs in einem Teilprogrammschritt mit zu erwärmender Spülflotte oder bereits erwärmter Spülflotte , z. B. „Reinigen" oder „Vorspülen", genutzt. Hierzu wird vorzugsweise während der Desorption des Sorbers 10 das Gebläse 13 eingeschaltet und die Luft aus dem Spülbehälter 2 durch die Leitungen 6, 7 und 9 entsprechend der Pfeile A, B und C umgewälzt. Hierbei erwärmt sich die Luft am Behälter 12 und insbesondere am Sorber 10. Vorzugsweise wird das Gebläse 13 erst dann eingeschaltet, wenn. die Temperatur im Behälter 12 höher ist als im Spülbehälter 2. Es ist auch möglich, dass während der Desorptionsphase die Luft über eine Bypassleitung (nicht dargestellt) um den Behälter 12 solange herumgeleitet wird, bis die Temperatur im Behälter 12 höher ist als im Spülbehälter 2. Die Erwärmung der Luft im Behälter 12 und insbesondere im Sorber 10 reicht weitgehendst aus, um die Spülflotte und/oder das Geschirr ausreichend zu erwärmen. Damit kann eine weitere Heizung weitgehendst entfallen und die zur Desorption eingesetzte Energie kann bis auf die geringe Energie, die zur Überwindung der Bindungskräfte zwischen Wasser und reversibel dehy- drierbarem Material benötigt wird, nahezu vollständig zur Erwärmung der Spülflotte und/oder des Geschirrs genutzt. Damit kann auf eine weitere Heizung weitgehendst verzichtet werden. Weiterhin ist neben der Energieeinsparung auch eine effiziente Reinigung des Spülgutes gewährleistet. Vorteilhafterweise kann dadurch auch Spülgut mit geringem Wärmeinhalt, z. B. Kunststoffteile, wirksam getrocknet werden, weil keine Erwärmung in dem Teilprogrammschritt, der dem Teilprogrammschritt „Trocknen" vorher geht, erforderlich. Die schnelle Trocknung ermöglicht auch ein stark reduziertes Keimwachstum oder gar ein völliges unterbinden des Keimwachstums, was sich vorteilhaft auf die hygienischen Verhältnisse am gereinigten Geschirr auswirkt. Mit der vorliegenden Erfindung ist eine Geschirrspülmaschine bereitgestellt, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Spülbehälter befindliche Spülgut effizient zu reinigen und zu trocknen sowie den damit verbundenen Energieaufwand so gering wie möglich zu halten. In the closed air system, an exchange of polluted air is excluded from the environment, whereby a Rückanschmutzung the treated material is prevented. A dishwasher is known to have a rinsing process on the pro form generally consisting of at least one partial program step "pre-rinsing", one part "cleaning", at least one subprogram step "intermediate rinsing", one subprogram step "rinsing" and one partial drying. According to the invention, in a subprogram step "drying "With the help of the blower 13 air from the washing container 2 via the inlet 5 through the lines 6, 7 and 9 and back through the inlet 8 into the washing 2. In the program step" drying "is in the washing 2 wet, to be dried Dishes with moist air. The valve 14 in the exchange line 15 is preferably opened. The reversibly dehydrogenatable material 11 contained in the sorber 10 has a relatively large capacity for moisture. Now, when the container 12 is connected to the sorbent column 10 by opening the valve 14, the reversibly dehydratable material 11 takes in a large amount of water contained in the container 12 in a short time 16 on and remaining in the container 12 remainder of water is strongly cooled by evaporative cold, z. B. until it freezes. The water 16 or ice in the container 12 evaporates or sublimates and the water vapor passes through the exchange line 15 to the sorber 10. In the sorber 10, the water vapor is absorbed by the reversibly dehydratable material 11. As a result of the heat of condensation occurring, the reversibly dehydratable material 11 and therefore the sorber 10 are heated. Cooling of the container 12 produces a very large temperature difference between the moist air and the condensation surface which arises on the inside of the line 6. The guided from the washing tank 2 moist air condenses. The resulting free condensation water must be dissipated, z. B. in the washing compartment 2 or in a separate reservoir (not shown). The air cooled and dehumidified on the container 12 is passed on to the sorber 10 via the line 7. The sorber 10 has a greatly elevated temperature, for. B. 90 °, due to the condensation occurring on. This leads to heating of the conducted air in the line 9, whereby the relative humidity 'decreases even further and the Fechtigkeitsaufnahmevermögen the air increases greatly. This dry and warm air is introduced into the washing container 2 via the inlet 8 and can both heat and dry the dishes to be dried here. The air introduced via the inlet 8 takes up moisture in the washing compartment 2 and cools down and is then introduced again into the conduit 6 via the outlet 5 in a closed circuit. The valve 14 is preferably opened during the "drying" partial program step, so that the cooling of the container 12, the heating of the sorber 10 and the circulation of air through the lines 6, 7 and 9 take place simultaneously the circulation of the air, the valve 14 are opened, so that already at the beginning of the circulation of air for drying the container 12 is cooled accordingly and the sorber 10 is heated and thus the full drying performance is available from the beginning during the recirculation of the air to be at least partially closed, because no additional cooling or heating is required due to the heat and cold storage capacity of the container 12 and the sorber 10. During other partial program steps that do not require drying, the valve 14 normally remains closed because unnecessary heating or cooling of the container 12 o the Sorbers 10 The reversibly dehydratable material 11 in the sorber 10 must be heated to very high temperatures for desorption, which is accomplished with the electric heating element 17. In this case, the stored liquid emerges as hot steam, which passes via the exchange line 15 with the valve 14 open to the container 12, which acts as a condenser, because the hot water vapor condenses in the container 12. Due to the heat of condensation of the container 12 and the water 16 is heated. The sorber 10 is heated by the electric heating element to high temperatures, eg. B. 150 ° - 200 °, heated. According to the invention, the heat energy used for desorption is at least partially heated to heat the rinsing liquor and / or the dishes in a partial program step with rinsing liquor to be heated or already warmed rinsing liquor, for. As "cleaning" or "pre-wash" used. For this purpose, the blower 13 is preferably turned on during the desorption of the sorber 10 and the air circulated from the washing container 2 through the lines 6, 7 and 9 according to the arrows A, B and C. In this case, the air heats up on the container 12 and in particular on the sorber 10. Preferably, the fan 13 is turned on only when. It is also possible that during the desorption phase, the air is bypassed via a bypass line (not shown) around the container 12 until the temperature in the container 12 is higher than in the washing container. 2 The heating of the air in the container 12 and in particular in the sorber 10 is largely sufficient to adequately heat the rinsing liquor and / or the dishes. Thus, a further heating can largely be dispensed with and the energy used for desorption can almost completely be used for heating the rinsing liquor and / or the dishes except for the low energy required to overcome the binding forces between water and reversibly dehydratable material. This can largely be dispensed with another heater. Furthermore, in addition to the energy savings and efficient cleaning of the dishes guaranteed. Advantageously, this also ware with low heat content, eg. Plastic parts are effectively dried because no heating is required in the partial program step preceding the partial program step "drying." The rapid drying also allows greatly reduced germ growth or even complete suppression of germ growth, which is beneficial to sanitary conditions The present invention provides a dishwasher with which it is possible, from an economic point of view, to efficiently clean and dry the items to be washed in the washing container and to minimize the energy expenditure associated therewith.
