The aim of the invention is to provide a method which allows items, contained in a processing chamber, to be effectively and efficiently dried from an economical point of view and the energy consumption to be thus maintained as low as possible, despite a very high drying power. Said aim is achieved, whereby a medium (16), in a container (12), is evaporated and/or sublimed and then cooled; the medium vapour, generated in said container (12), is absorbed by a reversible desiccating material (11) in an absorber (10) and the reversible desiccating material (11) is then heated; the air, contained in a processing chamber (2), is led to the cooled medium, whereby said air is cooled, in order to dehumidify the air by moisture condensation, and the cooled and dehumidified air is heated on the reversible desiccating material (11) and returned into the processing chamber (2).

Description

Verfahren zum Trocknen in einem Haushaltgerät Method of drying in a household appliance
Die Erfindung betrifft ein Verfahren zum Trocknen in einem Haushaltgerät, z. B. Wäschetrockner, Geschirrspülmaschine oder Schuhtrockner.The invention relates to a method for drying in a household appliance, for. B. tumble dryer, dishwasher or shoe dryer.
Zur Trocknung weist z. B. eine Geschirrspülmaschine bekanntlich ein Spülverfahren auf, dessen Programmablauf im Algemeinen aus wenigstens einem Teilprogrammschritt "Vorspülen", einem Teilprogrammschritt "Reinigen", wenigstens einem Teilprogrammschritt "Zwischenspülen", einem Teilprogrammschritt "Klarspülen" und einem Teilprogrammschritt "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.For drying has z. For example, a dishwasher is known to have a rinsing process whose program sequence generally consists of at least one partial program step "pre-rinsing", one sub-program step "cleaning", at least one sub-program step "intermediate rinsing", one sub-program step "rinsing" and one sub-program step "drying". 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.
Beispielsweise kann das Spülgut z. B. in einer Geschirrspülmaschine 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 Teilprogrammschritts "Trocknen" von selbst trocknet. Um diese Eigenwärmetrocknung zu erreichen, wird die Spülflüs- sigkeit 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.For example, the items to be washed z. B. are dried in a dishwasher by self-heating, when the rinse is heated in the program step "rinse" and thus the hot rinse washed items by the thus constructed material-dependent heat content of the items dried during the part program step "drying" by itself. In order to achieve this self-heat drying, the rinsing liquid is heated in the partial program step "rinsing" with a separate heating to a certain temperature and applied to the dishes by means of spraying devices present in the dishwasher. Due to the relatively high temperature of the rinsing liquid in the partial program step "rinsing" usually from 55 ° C to 75 ° C is achieved that a sufficiently large amount of heat is transferred to the items to be washed, so that the remaining water adhering to the dishes by stored in the ware Heat evaporates. The steam condenses on colder surfaces or is discharged by blower from the dishwasher.
Bei einer weiteren bekannten Trocknungseinrichtung beispielsweise in einer Geschirr- Spülmaschine 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 z. B. in Geschirrspülmaschinen besteht darin, dass die Erwärmung der Spülflüssigkeit 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 Teilprogrammschritt "Trocknen" selbst mit einem hohen Energiebedarf verbunden sind und die benötigte Wärmeenergie nach dem Trocknungsvorgang verloren geht, weil diese in die Umgebung entweichen.In a further known drying device, for example in a dishwasher, a separate heat source, such as a hot air blower, used in the washing to heat the humid air mixture during the drying process, so that the air in the washing can absorb a larger amount of moisture. A disadvantage of the heating systems described above according to the described prior art z. B. in dishwashers is that the heating of the rinsing liquid is connected to a relatively high energy demand and the required heat energy for each heating phase by means of the electric heating elements must be recreated. Likewise, the known heating systems have the disadvantage that the heating of the rinsing liquid in the program step "rinsing" and the operations in the sub-program step "drying" are themselves associated with high energy requirements and the required heat energy is lost after the drying process, because they escape into the environment.
Es sind z. B. 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.There are z. As dishwashers known in which 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.
Des Weiteren sind z. B. 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.Furthermore, z. As dishwashers, in which before passing the moist air is passed through condensation surfaces, where the moisture condenses. This condensation water is directed either into the rinsing container or into special collection containers.
Aus der DE 30 21 746 A1 ist z. B. 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 Spül- behälter 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.From DE 30 21 746 A1 z. For example, a method for operating a dishwasher is known in which a heat exchanger connected to the rinsing container is fed with cold fresh water during a partial program step "drying." This produces a condensation surface on the inside of the rinsing container, at which the moisture condenses and the resulting liquid is condensed Since the temperature difference between the moist air and the filled fresh water is relatively low and the fresh water quantity is constantly warming up, there is the disadvantage that the condensation of the humid air takes a long time and the condensation power is steadily reduced 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.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren bereitzustellen, mit der es möglich ist, unter wirtschaftlichen Gesichtspunkten das im Behandlungsraum befindliches Behandlungsgut effektiv und effizient zu trocknen und somit den Energieaufwand trotz sehr guter Trocknungsleistung so gering wie möglich zu halten.The object of the present invention is therefore to provide a method with which it it is possible to effectively and efficiently dry the material to be treated located in the treatment room from an economic point of view and thus to keep the energy expenditure as low as possible despite very good drying performance.
Diese Aufgabe wird durch das erfindungsgemäße Verfahren mit den Merkmalen gemäß Anspruch 1 gelöst.

In einer anderen Ausführungsform sind der Behälter mit Medium und der Sorber mit reversibel, dehydrierbarem Material über eine Austauschleitung mit einem Ventil zur Leitung des Mediumdampfes miteinander verbunden und vorzugsweise sind der Behälter, der Sorber und die Leitung eine nach außen geschlossene Einheit. Dadurch kann vorteilhafterweise die Aufnahme des Mediums vom reversiblen, dehydrierbaren Material durch das Ventil kontrolliert gesteuert werden und aufgrund der nach außen geschlossenen Einheit wird kein Medium verbraucht.In another embodiment, the container with medium and the sorber with reversible, dehydratable material are connected to each other via a replacement line with a valve for conducting the medium vapor and preferably, the container, the sorber and the conduit are an outwardly closed unit. As a result, the absorption of the medium from the reversible, dehydratable material can advantageously be controlled controlled by the valve and due to the unit closed to the outside, no medium is consumed.
Zweckmäßigerweise wird die Luft aus dem Behandlungsraum über einen Auslass in Leitungen von einem Gebläse zum Medium zum Abkühlen der Luft und zum reversiblen dehydrierbarem Mateial zum Erwärmen der Luft und wieder zurück über einen Einlass in den Behandlungsraum geleitet. Damit sind die beiden letzten Schritte des erfindungsgemäßen Verfahrens mit einer einfachen und zuverlässigen Vorrichtung, die im Wesentlichen nur Leitungen und ein Gebläse umfasst, durchführbar.Conveniently, the air is passed from the treatment space via an outlet in conduits from a fan to the medium for cooling the air and to the reversible dehydratable material for heating the air and back to the treatment space via an inlet. These are the last two steps of the inventive method with a simple and reliable device, which essentially comprises only lines and a blower feasible.
In einer anderen Ausführungsform wird das in den Leitungen kondensierte Wasser aus der Luft in den Behandllungsraum oder in einen gesonderten Auffangbehälter geleitet. Damit kann das Kondenswasser einfach entsorgt werden.In another embodiment, the condensed in the lines of water from the air in the treatment room or in a separate collection container is passed. Thus, the condensation can be easily disposed of.
In einer zusätzlichen Ausführungsform wird das reversibel, dehydrierbare Material zur Desorption erwärmt, der aus der Desorption des reversiblen, dehydrierbaren Materials freigesetzte Mediumdampf im Behälter kondensiert und wodurchsich das Medium erwärmt, Luft aus dem Behandlungsraum zum erwärmten reversiblen dehydrierbaren Material und wieder zurück in den Behandlungsraum geleitet und sich die Luft dadurch erwärmt. Damit kann die zur Desorption des reversiblen, dehydrierbaren Materials eingesetzte Wärmeenergie vorteilhafterweise wenigstens teilweise zur Erwärmung des im Behandlungsraum befindlichen Behandlungsgutes, z. B. Geschirr, und/oder der Behandlungsflüssigkeit, z. B. Spülflotte, eingesetzt werden.In an additional embodiment, the desorbable, dehydratable material is heated to condense the medium vapor released from the desorption of the reversible dehydrogenatable material into the vessel, thereby heating the medium, passing air from the treatment space to the heated reversible dehydrogenatable material and back into the treatment space and the air heats up. Thus, the thermal energy used for the desorption of the reversible, dehydratable material advantageously at least partially for heating the treatment material located in the treatment room, for. As tableware, and / or the treatment liquid, for. B. rinse liquor used.
Zweckmäßigerweise wird Luft aus dem Behandlungsraum zum Medium und wieder zurück in den Behandlungsraum geleitet, wodurch sich die Luft vorzugsweise erwärmt. Damit kann vorteilhafterweise auch das im Behälter befindliche Medium zum erwärmen der Behandlungsflüssigkeit und/oder des Behandlungsgutes eingesetzt werden.Conveniently, air is passed from the treatment room to the medium and back into the treatment room, whereby the air is preferably heated. Thus, advantageously, the medium in the container for heating the treatment liquid and / or the treated material can be used.
Vorteilhafterweise wird das reversible, dehydrierbare Material zur Desorption von einem elektrischen Heizelement erwärmt.Advantageously, the reversible, dehydratable material is heated by an electric heating element for desorption.
In einer bevorzugten Ausführungsform wird die Luft aus dem Behandlungsraum über einen Auslass in Leitungen von einem Gebläse zum Medium zum vorzugsweise Erwärmen der Luft und zum reveriblen dehydrierbarem Mateial zum Erwärmen der Luft und wieder zurück über einen Einlass in den Behandlungsraum geleitet. Damit ist die Leitung der Luft zum Medium und zum reversiblen dehydrierbaren Material mit einer einfachen und zuverlässigen Vorrichtung möglich.In a preferred embodiment, the air is passed from the treatment space via an outlet in conduits from a fan to the medium for preferably heating the air and the reverible dehydratable material for heating the air and back into the treatment space via an inlet.

Fig. 1 einen schematisierten Querschnitt durch eine Geschirrspülmaschine zur Durchführung des erfindungsgemaßen Verfahrens.Fig. 1 is a schematic cross section through a dishwasher for carrying out the inventive method.
Das Haushaltgerät, z.B. die Geschirrspülmaschine 1 weist einen geschlossenen Luftkreis auf, der durch die Leitungen 6, 7 und 9 sowie den Behandlungsraum 2 mit Geschirrkörben 3, 4 führt. Im Behandlungsraum 2 befindet sich das Behandlungsgut, z. B. Geschirr (nicht dargestellt). Im oberen Bereich des Behandlungsraumes, z. B. Spülbehälters 2, befindet sich ein Auslass 5 aus dem Spülbehälter 2, in dem die Luft in die Leitung 6 einströmt, siehe Pfeil A. Im unteren Bereich des Spülbehälters 2 befindet sich ein Einlass 8, in dem die Luft aus der Leitung 9 in den Spülbehälter 2 einströmt, siehe Pfeil C. Zwischen der Leitung 6 und 9 ist die Leitung 7 mit dem Gebläse 13 angeordnet, welches die Luft in der Leitung 7 in Strömungsrichtung gemäß Pfeil B fördert. Am Ende der Leitung 6 befindet sich in der Leitung 6 ein Behälter 12, der mit einem Medium, z. B. 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 ein 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.The household appliance, e.g. the dishwasher 1 has a closed air circuit, which leads through the lines 6, 7 and 9 and the treatment room 2 with crockery baskets 3, 4. In the treatment room 2 is the treated, z. B. dishes (not shown). In the upper area of the treatment room, z. B. rinsing tank 2, there is an outlet 5 from the washing compartment 2, in which the air flows into the conduit 6, see arrow A. In the lower part of the washing compartment 2 is an inlet 8, in which the air from the line 9 in the purge vessel 2 flows, see arrow C. Between the line 6 and 9, the conduit 7 is arranged with the fan 13, which promotes the air in the conduit 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 connected to a medium, for. B. water 16 or ice is filled. 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 line 9, a sorber 10 is arranged 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.
Bei dem geschlossenen Luftsystem ist ein Austausch von verschmutzter Luft aus der Umgebung ausgeschlossen, womit eine Rückanschmutzung des behandelten Gutes ver- hindert wird.In the closed air system, the exchange of polluted air from the environment is excluded, which prevents back soiling of the treated material.
Eine Geschirrspülmaschine weist bekanntlich ein Spülverfahren auf dessen Programmablauf im Allgemeinen aus wenigstens einem Teilprogrammschritt "Vorspülen", einem Teilprogrammschritt "Reinigen", wenigstens einem Teilprogrammschritt "Zwischen- spülen", einem Teil programmschritt "Klarspülen" und einem Teilprogrammschritt "Trocknen" besteht.A dishwasher has, as is known, a rinsing method on its program sequence, generally comprising at least one partial program step "prewash", a subprogram step "cleaning", at least one partial program step "intermediate". rinse ", a part program step" rinse "and a sub-program step" drying "is.
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.According to the invention, in a partial program step "drying" with the aid of the blower 13, air is passed from the rinsing container 2 via the inlet 5 through the lines 6, 7 and 9 and back into the rinsing container 2 via the inlet 8. In the partial program step "Drying" is located in the rinse tank 2 wet, to be dried dishes with humid air. The valve 14 in the exchange line 15 is preferably opened.
Das im Sorber 10 enthaltene reversibel dehydrierbare Material 11 hat eine verhältnismä- ßig große Kapazität zur Feuchtigkeitsaufnahme. Wird 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 zwi- sehen 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. 140°, 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 Feuchtigkeitsaufnahmevermögen 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 An- fang 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.The reversibly dehydratable material 11 contained in the sorber 10 has a relatively large capacity for absorbing moisture. Now, if the container 12 is connected to the sorption column 10 by opening the valve 14, the reversibly dehydratable material 11 takes in a short time a large amount of the water contained in the container 12 16 and remaining in the container 12 remaining water is by evaporative cooling strongly cooled, 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. Due to the condensation heat occurring, the reversibly dehydratable material 11 and thus 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. 140 °, 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 moisture absorption capacity of 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. Preferably, the valve 14 is opened during the partial program step "Drying", so that the cooling of the container 12, the heating of the sorber 10 and the circulation of air through the conduits 6, 7 and 9 takes place simultaneously, however, it is also possible to open the valve 14 before the circulation of the air begins, so that already at the beginning of the recirculation of the air to dry the container 12 is cooled accordingly and the sorber 10 is heated and thus the full drying capacity is available from the beginning.Furthermore, the valve can also be at least partially closed during the circulation of air 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 sub-program steps that do not require drying, the valve 14 will normally remain closed because it will unnecessarily heat or cool the container 12 or Sorber's 10 would be achieved.
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. 200° - 300°, erhitzt. Erfmdungsgemäß wird die zur Desorption eingesetzte Wärmeenergie 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 Bypasslei- tung (nicht dargestellt) um den Behälter 12 solange herumgeleitet wird, bis die Tempera- tur 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 dehydrierbarem 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 ist. 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.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. 200 ° - 300 °, heated. According to the invention, the thermal 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 heated 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 the temperature in the container 12 is higher than in the washing container 2. It is also possible that during the desorption phase, the air via a Bypasslei tion (not shown) around the container 12 until the temperature in the container 12 is higher than in the rinsing container 2. The heating of the air in the container 12 and in particular in the sorber 10 is largely sufficient to remove the rinsing liquor and / or or to warm the dishes sufficiently. This can largely account for a further heating and the energy used for desorption can, except for the low energy, the is needed to overcome the binding forces between water and reversibly dehydratable material, almost completely used for heating the rinse liquor and / or the dishes. 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 inhibition of germ growth, which is beneficial to the hygienic Conditions on the cleaned dishes affects.
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. With the present invention, a dishwasher is provided, with which it is possible to efficiently clean and dry the dishes located in the washing container and to keep the associated energy consumption as low as possible.
