Description

Technisches GebietTechnical field

Die Erfindung betrifft eine Trocknungseinrichtung zum Trocknen von Geschirr- und/oder Tabletteilen auf einem Transportband einer Durchlaufgeschirrspülvorrichtung sowie ein Verfahren zum Trocknen von Geschirr- und/oder Tabletteilen in einer erfindungsgemäßen Vorrichtung.The invention relates to a drying device for drying of crockery and / or tablet parts on a conveyor belt a continuous dishwashing device and a method for Drying dishes and / or tablet parts in one device according to the invention.

Stand der TechnikState of the art

In herkömmlichen Durchlaufgeschirrspülvorrichtungen werden die zu behandelnden Geschirr- und/oder Tabletteile auf einem Transportband angeordnet und nacheinander durch die jeweiligen Behandlungszonen einer stationären Vorrichtung geführt. Nach einer Vorreinigungs-, einer Reinigungs- sowie einer Spülzone schließt sich üblicherweise eine Trocknungszone an, in welcher die in der Spülzone mit klarem Wasser gespülten Geschirr- und/oder Tabletteile mit erwärmter Luft beaufschlagt werden, welche über die Oberflächen der zu trocknenden Teile strömt und die Feuchte aufnimmt.In conventional continuous dishwashers, the crockery and / or tablet parts to be treated on one Conveyor belt arranged and successively by the respective Treatment zones of a stationary device led. To a pre-cleaning, a cleaning and a rinsing zone usually follows a drying zone in which the crockery washed in the washing zone with clear water and / or tablet parts are subjected to heated air, which flows over the surfaces of the parts to be dried and absorbs the moisture.

Da diese Art von Konvektionstrocknung einen hohen Energieeinsatz für die Erwärmung der Trocknungsluftströme erfordert, soll die eingesetzte Energie in bestmöglicher Weise ausgenutzt werden.Because this type of convection drying is high Use of energy to heat the drying air flows required, the energy used should be in the best possible way Way to be exploited.

Bei herkömmlichen Trocknungseinrichtungen in Durchlaufgeschirrspülvorrichtungen wird die Trocknungsluft durch geeignete Austrittsdüsen von oben auf die zu trocknenden Geschirrteile gerichtet und von einem Bodenblech, das unter dem Transportband angeordnet ist, aufgefangen. Von dort aus wird die Luft teilweise nach oben zurückreflektiert, teilweise jedoch verläßt diese in Bewegungsrichtung des Transportbandes die Vorrichtung. Hierdurch wird Trocknungsluft, die noch nicht vollständig mit Feuchte gesättigt ist, aus der Vorrichtung abgeführt, wodurch zum einen eine unerwünschte Erwärmung der die Durchlaufgeschirrspülvorrichtung umgebenden Raumluft stattfindet, zum anderen sich aber auch die benötigte Heizleistung erhöht und der benötigte Trocknungsgrad nicht erreicht wird, da vornehmlich Umgebungstemperatur von dem Gebläse angesaugt und auf die gewünschte Trocknungstemperatur gebracht werden muß.In conventional drying facilities in Continuous dishwashing equipment becomes the drying air through suitable outlet nozzles from above towards the drying dishes directed from a floor pan, which is located under the conveyor belt. Of from there the air is partially reflected back upwards, partially, however, it leaves in the direction of movement of the Conveyor belt the device. This will Drying air that is not completely damp is saturated, discharged from the device, causing the an undesirable warming of the Continuous dishwashing device surrounding ambient air takes place, but also the required Heating output increases and the required degree of drying does not is achieved, as mainly ambient temperature from the Blower sucked in and to the desired drying temperature must be brought.

In der US-A-4561904 ist eine Trocknungseinrichtung zum Trocknen von Geschirr- und/oder Tabletteilen auf einem Transportband einer Durchlaufgeschirrspülvorrichtung beschrieben. Die Vorrichtung umfaßt ein Trocknungsgebläse mit einer damit verbundenen Luftverteilungseinrichtung und erste Austrittsdüsen für Trocknungsluft über dem Transportband. Ferner umfaßt sie eine Umlenkwanne und zweite Luftaustrittsöffnungen unter dem Transportband, die in Bewegungsrichtung des Transportbands vor den ersten Austrittsdüsen plaziert sind.In US-A-4561904 a drying device for Drying dishes and / or tablet parts on one Conveyor belt of a continuous dishwasher described. The device includes a drying fan an associated air distribution device and first Outlet nozzles for drying air above the conveyor belt. It also includes a deflecting tub and second Air outlet openings under the conveyor belt, which in Direction of movement of the conveyor belt before the first Outlet nozzles are placed.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine Trocknungseinrichtung sowie ein Verfahren zum Trocknen von Geschirr- und/oder Tabletteilen vorzuschlagen, die eine gute Ausnutzung der eingesetzten Energie gestattet und die gesamte Luftführung in der Trocknungszone verbessert.The invention has for its object a Drying device and a method for drying Propose dishes and / or tablet parts that are good Utilization of the energy used allowed and the whole Airflow in the drying zone improved.

Diese Aufgabe wird durch eine Trocknungseinrichtung mit den Merkmalen des Patentanspruches 1 gelöst sowie durch ein Trocknungsverfahren mit den Merkmalen des Anspruches 8.This task is performed by a drying device with the Features of claim 1 solved and by a Drying method with the features of claim 8.

Der Erfindung liegt der Gedanke zugrunde, durch den gezielten Austritt der Trocknungsluft aus Luftaustrittsdüsen sowie durch das gezielte Umlenken der Trocknungsluft diese so zu führen, daß ein hoher Anteil der Trocknungsluft in der Trocknungseinrichtung umgewälzt werden kann.The invention is based on the idea of targeted The drying air escapes from the air outlet nozzles as well by specifically deflecting the drying air cause a high proportion of the drying air in the Drying device can be circulated.

Dies wird durch eine Luftverteileinrichtung sowie durch eine Umlenkwanne erreicht, die dahingehend zusammenwirken, daß die Trocknungsluft gezielt durch erste und zweite Luftaustrittsdüsen über bzw. unter dem Transportband austritt und auf die zu trocknenden Gegenstände gerichtet wird, und die aus den ersten Luftaustrittsdüsen austretende Trocknungsluft in einer Umlenkwanne so zwangsgeführt wird, daß diese mehrere Male über die zu trocknenden Gegenstände streicht und in Richtung des Trocknungsgebläses geführt wird. Unter dem Begriff Transportband wird im folgenden derjenige Teil des als Endlosband ausgeführten Transportbandes verstanden, auf dem sich die zu trocknenden Geschirr- und/oder Tabletteile befinden.This is done by an air distribution device and by a Deflection tank achieved that work together so that the Drying air targeted through first and second Air outlet nozzles emerge above or below the conveyor belt and is directed at the objects to be dried, and the one emerging from the first air outlet nozzles Drying air is forced into a deflection tank that this several times over the objects to be dried strokes and is guided in the direction of the drying fan. In the following, the term conveyor belt is used Part of the conveyor belt designed as an endless belt understood on which the dishes to be dried and / or tablet parts.

Dabei sind die zweiten Luftaustrittsdüsen in Bewegungsrichtung des Transportbandes sowohl vor als auch hinter den ersten Austrittsdüsen in der Umlenkwanne angeordnet. Indem die aus den ersten Luftaustrittsdüsen austretende Trocknungsluft von oben nach unten entlang der zu reinigenden Teile geführt und von der Umlenkwanne aufgefangen wird, bildet sich in der Umlenkwanne ein Bereich aus, in dem die Trocknungsluft ihre Richtung ändert und die Umlenkwanne im wesentlichen nach oben wieder verläßt. Diese Umlenkung der aus den ersten Austrittsdüsen geförderten Trocknungsluft wird dadurch unterstützt, daß in Bewegungsrichtung des Transportbandes vor und hinter dem Umlenkbereich Trocknungsluft mit einer nach oben gerichteten Bewegung aus den zweiten Luftaustrittsdüsen entweicht. Hierdurch bildet sich in Bewegungsrichtung des Transportbandes vor und hinter dem Umlenkbereich in der Umlenkwanne eine natürliche Barriere, welche die möglichst weitgehende Umlenkung der aus den ersten Austrittsdüsen stammenden Trocknungsluft unterstützt. Zudem wirken die aus den zweiten Luftaustrittsdüsen austretenden Ströme an Trocknungsluft einen gewissen Schleppeffekt auf die in der Umlenkwanne strömende Luft aus.The second air outlet nozzles are in Direction of movement of the conveyor belt both before and behind the first outlet nozzles in the deflection tank arranged. By taking out the first air outlet nozzles escaping drying air from top to bottom along the cleaning parts out and collected by the deflection tub an area is formed in the deflection tank in which the drying air changes direction and the deflection pan essentially leaves up again. This redirection of the drying air conveyed from the first outlet nozzles supported by the fact that in the direction of movement of the Conveyor belt in front of and behind the deflection area Drying air with an upward movement escapes from the second air outlet nozzles. This forms in front of and behind in the direction of movement of the conveyor belt the deflection area in the deflection tub is a natural one Barrier that redirects as far as possible from the drying air coming from the first outlet nozzles supported. In addition, they work from the second Air outlet nozzles exiting flows of drying air a certain drag effect on those in the deflection tub flowing air out.

Bevorzugte Ausführungsformen sind durch die übrigen Ansprüche gekennzeichnet. Preferred embodiments are defined by the remaining claims featured.

So weisen die ersten und zweiten Luftaustrittsdüsen nach einer bevorzugten Ausführungsform Luftaustrittsschlitze auf, deren Längserstreckung im wesentlichen quer zur Bewegungsrichtung des Transportbandes verläuft. Durch das Vorsehen von Luftaustrittsschlitzen wird ein gleichmäßiger "Luftvorhang" an Trocknungsluft erzeugt, durch den die zu trocknenden Teile hindurchtreten müssen.So the first and second air outlet nozzles point to one preferred embodiment air outlet slots on whose Longitudinal extension essentially transverse to the direction of movement of the conveyor belt runs. By providing Air outlet slots will create an even "air curtain" Drying air generated by the parts to be dried have to step through.

Vorzugsweise ist die Umlenkwanne quer zur Bewegungsrichtung des Transportbandes verschiebbar angeordnet und schubladenartig ausziehbar. Dies besitzt den Vorteil, daß sich die Umlenkwanne auf besonders einfache Weise reinigen läßt.The deflection trough is preferably transverse to the direction of movement of the conveyor belt slidably arranged and extendable like a drawer. This has the advantage that can clean the deflecting tub in a particularly simple manner.

Nach einer bevorzugten Ausführungsform der Erfindung umfaßt die Luftverteilungseinrichtung einen über dem Transportband angeordneten Querkanal, der quer zur Bewegungsrichtung des Transportbandes verläuft und die ersten Luftaustrittsdüsen aufweist, mindestens einen in Bewegungsrichtung des Transportbandes verlaufenden Längskanal und mindestens einen im wesentlichen vertikal verlaufenden Zwischenkanal, der mit dem Querkanal und dem Längskanal verbunden ist, wobei der Längskanal Luftdurchtrittsöffnungen besitzt, die mit den zweiten Luftaustrittsdüsen in Strömungsverbindung stehen. Durch diese Gestaltung der Luftverteilungseinrichtung läßt sich der von dem Gebläse gelieferte Strom an Trocknungsluft sowohl den ersten Luftaustrittsdüsen zuführen, die an dem Querkanal über dem Transportband angeordnet sind, als auch über die Zwischenkanäle und Längskanäle den zweiten Luftaustrittsdüsen im Bereich der Umlenkwanne zuführen, die unter dem Transportband angeordnet sind. Durch diese gezielte Luftführung tritt die Trocknungsluft sowohl von unten als auch von oben in Richtung der zu trocknenden Teile aus den jeweiligen Luftaustrittsdüsen aus.According to a preferred embodiment of the invention the air distribution device one above the conveyor belt arranged transverse channel which is transverse to the direction of movement of the Conveyor belt runs and the first air outlet nozzles has at least one in the direction of movement of the Conveyor belt running longitudinal channel and at least one essentially vertical intermediate channel that with the transverse channel and the longitudinal channel is connected, the Longitudinal channel has air passage openings that with the second air outlet nozzles are in flow connection. This design allows the air distribution device the flow of drying air supplied by the blower feed both the first air outlet nozzles, which on the Cross channel are arranged above the conveyor belt, as well the second via the intermediate channels and longitudinal channels Feed air outlet nozzles in the area of the deflection trough are arranged under the conveyor belt. Through this targeted Air routing enters the drying air both from below and from above towards the parts to be dried from the respective air outlet nozzles.

Nach einer bevorzugten Ausführungsform ist an dem mindestens einen Zwischenkanal jeweils mindestens eine dritte Luftaustrittsdüse angeordnet, deren Geometrie einen Luftaustritt erzeugt, der im wesentlichen quer zur Bewegungsrichtung des Transportbandes horizontal ist. Hierdurch läßt sich in einfacher Weise ein gerichteter Strom an Trocknungsluft erzeugen, der die zu trocknenden Geschirr- und/oder Tabletteile von der Seite beaufschlagt.According to a preferred embodiment, at least an intermediate channel at least a third each Air outlet nozzle arranged, the geometry of one Air outlet generated, which is essentially transverse to Direction of movement of the conveyor belt is horizontal. This allows a directed current to be produced in a simple manner generate drying air that the dishes to be dried and / or tablet parts from the side.

Vorzugsweise sind die zweiten Luftaustrittsdüsen in Formkörpern gebildet, die in der Umlenkwanne herausnehmbar eingelegt sind. Dies erleichtert die Reinigung der Vorrichtung im Bereich der Umlenkwanne, indem die Formkörper mit den darauf gebildeten Luftaustrittsdüsen vor der Reinigung ohne die Verwendung von Werkzeugen lediglich herausgenommen werden können. Ein weiterer Vorteil liegt darin, daß für verschiedene, zu trocknende Teile Formkörper eingesetzt werden können, deren Düsengeometrie speziell auf die zu trocknenden Teile in bestmöglicher Weise abgestimmt ist. Hierdurch besteht die Möglichkeit, die Trocknungseinrichtung auf eine sehr schnelle und bequeme Weise jeweils wechselnden Bedürfnissen anzupassen und auf unterschiedliche, zu trocknende Teile umzurüsten. The second air outlet nozzles are preferably in Shaped bodies formed, which can be removed in the deflecting tub are inserted. This makes cleaning the Device in the area of the deflection pan by the molded body with the air outlet nozzles formed on it in front of the Cleaning without the use of tools only can be removed. Another advantage lies in that moldings for various parts to be dried can be used, the nozzle geometry specifically the parts to be dried matched in the best possible way is. This gives the opportunity to Drying device on a very quick and convenient Way to adapt to changing needs converting different parts to be dried.

Vorzugsweise besitzen die in Bewegungsrichtung des Transportbandes vor den ersten Luftaustrittsdüsen gelegenen zweiten Luftaustrittsdüsen, d.h. diejenigen zweiten Luftaustrittsdüsen, die von den zu trocknenden Geschirr- und/oder Tabletteilen auf dem Transportband später erreicht werden, jeweils eine Austrittsöffnung, die eine Luftaustrittsrichtung nach oben in einem Winkel gegen die Bewegungsrichtung des Transportbandes erzeugen. Hierdurch läßt sich der Wärmeverlust der Trocknungseinrichtung und somit der Energieausnutzungskraft weiter erhöhen, weil diejenigen Strömungsanteile, die aus der Vorrichtung entweichen können, möglichst gering gehalten werden. Der Neigungswinkel zur Senkrechten liegt hierbei vorzugsweise bei etwa 5 Grad bis 30 Grad.Preferably have in the direction of movement Conveyor belt in front of the first air outlet nozzles second air outlet nozzles, i.e. those second Air outlet nozzles that are from the dishes to be dried and / or tablet parts reached later on the conveyor belt are each an outlet opening, the one Air outlet direction upwards at an angle against the Generate the direction of movement of the conveyor belt. Hereby the heat loss of the drying device and thus further increase the energy utilization because those flow components that come from the device can escape, be kept as low as possible. The Angle of inclination to The vertical is preferably about 5 degrees to 30 Degree.

Das Kernstück der Trocknungseinrichtung 10, die in der Geschirrspülvorrichtung in einem Gehäuse (nicht dargestellt) angeordnet ist, bildet ein Gebläse 16, das vorzugsweise ein Radialgebläse ist. Durch einen Lufteinlaß 18 wird Luft in das Gebläse 16 eingesaugt und in einer Heizeinrichtung 20, z.B. in Form von luftstromdurchflossenen Heizmedien, erhitzt. Die erhitzte Trocknungsluft gelangt anschließend in eine Luftverteilungseinrichtung 22, die über dem Transportband 14 und somit den zu trocknenden Geschirr- und/oder Tabletteilen 12 erste Austrittsdüsen 24 für Trocknungsluft aufweist.The core of the drying device 10, which in the Dishwasher device in a housing (not shown) is arranged, forms a fan 16, which preferably Radial blower is. Through an air inlet 18 air is in the Blower 16 is sucked in and placed in a heating device 20, e.g. in Form of air flow-through heating media, heated. The heated drying air then gets into a Air distribution device 22, which is above the conveyor belt 14 and thus the dishes and / or tablet parts to be dried Has 12 first outlet nozzles 24 for drying air.

Wie am besten aus Fig. 2 ersichtlich ist, besteht die Luftverteilungseinrichtung 22 aus einem Querkanal 26, dessen untere Fläche in Fig. 2 dargestellt ist und der im wesentlichen horizontal und senkrecht zur Bewegungsrichtung A des Transportbandes 14 verläuft, zwei Zwischenkanäle 28, die mit dem Querkanal 26 jeweils verbunden sind sowie zwei Längskanäle 30 (siehe Fig. 2), die mit einer Umlenkwanne 32 verbunden sind.As best seen in Fig. 2, there is Air distribution device 22 from a transverse channel 26, the lower surface is shown in Fig. 2 and in essentially horizontal and perpendicular to the direction of movement A of the conveyor belt 14, two intermediate channels 28 which are each connected to the transverse channel 26 and two Longitudinal channels 30 (see FIG. 2) with a deflecting trough 32 are connected.

Sämtliche Bauteile der Luftverteilungseinrichtung 22 sowie der Umlenkwanne 32 mit den darin eingelegten Formkörpern sind vorzugsweise aus Edelstahl gefertigt.All components of the air distribution device 22 and the Deflection trough 32 with the molded bodies inserted therein preferably made of stainless steel.

Die ersten Austrittsdüsen 24 auf dem Querkanal 26 befinden sich zwischen den Zwischenkanälen 28 und lenken die erhitzte Trocknungsluft von oben in Richtung auf das Transportband 14 mit den darauf angeordneten, zu trocknenden Geschirr- und/oder Tabletteilen 12. Nach dem Entlangstreichen entlang der zu trocknenden Teile und dem Hindurchtreten durch das Transportband hindurch trifft die Trocknungsluft auf die Umlenkwanne 32 und wird, wie in Figur 1 anhand der schematischen Pfeile B gezeigt ist, in der Umlenkwanne 32 so in seiner Richtung verändert, daß die Trocknungsluft anschließend von unten nach oben wieder durch das Transportband 14 hindurchtritt und nochmals über die zu trocknenden Geschirr- und/oder Tabletteile streicht.The first outlet nozzles 24 are located on the transverse channel 26 between the intermediate channels 28 and direct the heated Drying air from above towards the conveyor belt 14 with the crockery and / or Tablet parts 12. After swiping along the to drying parts and passing through the The drying air hits the conveyor belt Deflection pan 32 and, as in Figure 1 using the schematic arrows B is shown in the deflection pan 32 so changed in its direction that the drying air then from the bottom up again through the Conveyor belt 14 passes through and again over the drying dishes and / or tablet parts.

Derjenige Anteil der Trocknungsluft, der nicht durch die ersten Austrittsdüsen 24 austritt, strömt in die Zwischenräume 28 ein, wobei die vorzugsweise als hohle, rechteckige Körper ausgebildeten Zwischenkanäle 28 mit dem Querkanal 26 so in Strömungsverbindung stehen, daß sich ein kommunizierender Hohlraum für die Trocknungsluft zwischen dem Querkanal und dem Zwischenkanal befindet. Die Menge der jeweils durch die ersten Austrittsdüsen und in die Zwischenkanäle eintretenden Trocknungsluft richtet sich nach der Geometrie der gesamten Luftverteilungseinrichtung 22 und dem jeweiligen Druckverlust der einzelnen Teilluftströme in der Luftverteilungseinrichtung.That part of the drying air that is not through the first outlet nozzles 24 flows into the spaces 28 a, the preferably as a hollow, rectangular body formed intermediate channels 28 with the transverse channel 26 in Flow connection are that a communicating Cavity for the drying air between the cross channel and the Intermediate channel is located. The amount of each by the first Outlet nozzles and entering the intermediate channels Drying air depends on the geometry of the whole Air distribution device 22 and the respective pressure loss of the individual partial air flows in the Air distribution device.

Vorteilhafterweise befindet sich jeweils in den Zwischenkanälen 28 eine seitliche Düse 34, durch welche die zu trocknenden Gegenstände quer zu ihrer Transportrichtung und im wesentlichen aus einer horizontalen Richtung zusätzlich mit Trocknungsluft beaufschlagt werden.Each is advantageously located in the Intermediate channels 28 a side nozzle 34 through which the to drying objects transversely to their direction of transport and in essentially from a horizontal direction Drying air can be applied.

In Fig. 2, in der auf den beiden Zwischenkanälen 28 jeweils nur die nach unten gerichtete Abschlußfläche des Querkanales 26 dargestellt ist, sind neben den ersten Austrittsdüsen 24 auch Öffnungen 33 dargestellt, welche die Verbindung zwischen dem Querkanal 26 und den Zwischenkanälen 28 verdeutlichen sollen. Die Geometrie der Durchtrittsöffnungen 33 ist nur als Beispiel gezeigt und richtet sich nach den Strömungsbedingungen in der gesamten Luftverteilungseinrichtung 22 und insbesondere dem erwünschten Druckverlust der Trocknungsluft beim Eintritt vom Querkanal in die Zwischenkanäle.2, in each case on the two intermediate channels 28 only the end face of the cross channel pointing downwards 26 are shown, in addition to the first outlet nozzles 24 openings 33 are also shown, which the connection between clarify the transverse channel 26 and the intermediate channels 28 should. The geometry of the passage openings 33 is only as Example shown and depends on the Flow conditions throughout Air distribution device 22 and in particular the desired Pressure loss of the drying air when entering the cross channel in the intermediate channels.

Nach dem Durchströmen der Zwischenkanäle gelangt die Trocknungsluft in die sich an diese anschließenden Längskanäle 30, wobei die Strömungskanäle für die Trocknungsluft in den Zwischenkanälen 28 und in den Längskanälen 30 miteinander in Verbindung stehen. Die Längskanäle 30 dienen dazu, die Trocknungsluft den zweiten Luftaustrittsdüsen 36 in der Umlenkwanne 32 zuzuführen. Hierzu sind in der Umlenkwanne 32 Formkörper 38 eingelegt, welche die zweiten Luftaustrittsdüsen 36 aufweisen sowie einen geschlossenen Hohlkörper, welcher der Verteilung der Trocknungsluft von den Längskanälen 30 zu den zweiten Luftaustrittsdüsen 36 hin dient. Die aus den zweiten Austrittsdüsen 36 austretende Trocknungsluft gelangt von den Längskanälen 30 in die Formkörper 38 durch geeignete Öffnungen (nicht dargestellt) zwischen den Längskanälen 30 und den in die Umlenkwanne 32 eingelegten Formkörpern 38.After flowing through the intermediate channels, the Drying air into the longitudinal channels connected to these 30, the flow channels for the drying air in the Intermediate channels 28 and in the longitudinal channels 30 with each other in Connect. The longitudinal channels 30 serve the Drying air the second air outlet 36 in the Feed the deflector pan 32. For this purpose, 32 Shaped body 38 inserted, which the second air outlet nozzles 36 have and a closed hollow body, which the Distribution of the drying air from the longitudinal channels 30 to the second air outlet nozzle 36 serves. The second Exit nozzles 36 exiting drying air passes from the Longitudinal channels 30 in the molded body 38 through suitable openings (not shown) between the longitudinal channels 30 and the in the deflection trough 32 inserted molded bodies 38.

Die Formkörper 38 sind vorzugsweise so gestaltet, daß sie aus der Umlenkwanne 32 bequem und ohne Verwendung von Werkzeugen herausnehmbar sind, so daß sich die Vorrichtung 10 im Bereich der Umlenkwanne leicht reinigen läßt. Aus demselben Grund kann die Umlenkwanne vorteilhafterweise im Rahmen regelmäßiger Reinigungsarbeiten ohne die Verwendung von Werkzeugen aus der Vorrichtung 10 entnommen werden, beispielsweise indem die Umlenkwanne in Form einer Schublade ausgestaltet ist und in geeigneter Weise auf Schienen oder einem anderen Führungselement läuft und seitlich, d.h. in Fig. 1 senkrecht zur Zeichenebene, aus der Vorrichtung 10 entnommen werden kann.The shaped bodies 38 are preferably designed so that they are made of the deflection tray 32 conveniently and without the use of tools are removable so that the device 10 in the area the deflecting tub can be easily cleaned. For the same reason the deflecting tub advantageously within the framework of regular Cleaning work without the use of tools from the Device 10 are removed, for example by the Deflection tub is designed in the form of a drawer and in suitably on rails or another Guide element runs and sideways, i.e. in Fig. 1 vertically to the drawing plane, can be removed from the device 10 can.

Wendet man sich wieder der Fig. 1 zu, so ist der Austritt der Trocknungsluft aus den Formkörpern 38 schematisch durch die Pfeile C und D dargestellt. Während der in Bewegungsrichtung des Transportbandes vorne in der Umlenkwanne gelegene Formkörper 38b drei Austrittsdüsen 36 aufweist, sind in hinten angeordneten Formkörper 38a zwei Austrittsdüsen gebildet.Turning back to Fig. 1, the exit is the Drying air from the moldings 38 schematically through the Arrows C and D are shown. During the movement of the conveyor belt located in the front of the deflection trough Shaped body 38b has three outlet nozzles 36 are in the rear arranged shaped body 38a formed two outlet nozzles.

Wie in Fig. 1 dargestellt ist, besitzen die zweiten Luftaustrittsdüsen 36 in den Formkörpern 38a und 38b eine Geometrie, die einen Luftaustritt nach oben in einem Winkel zur Bewegungsrichtung der Geschirr- und/oder Tabletteile auf dem Transportband 14 erzeugt. Während der in Bewegungsrichtung A vor den Zwischenkanälen 28 angeordnete Formkörper 38b eine Luftaustrittsrichtung in einem Winkel entgegen der Senkrechten zur Bewegungsrichtung A des Transportbandes 14 erzeugt, besitzt der andere Formkörper 38a im dargestellten Ausführungsbeispiel Düsen, die sowohl in einem Winkel in Richtung der Bewegungsrichtung als auch entgegen der Bewegungsrichtung des Transportbandes angeordnet sind. Die Winkel α zur Senkrechten liegen hierbei zwischen 5 Grad und 30 Grad und vorzugsweise bei etwa 15 Grad. Da sich bei der in Fig. 1 gezeigten, unterbrochenen Linie der Austritt aus der Trocknungseinrichtung 10 und somit der gesamten Durchlaufgeschirrspülvorrichtung befindet, wird durch den gezielten Austritt der Trocknungsluft in Pfeilrichtung C aus den zweiten Luftaustrittsdüsen 36 sichergestellt, daß nur ein geringer Anteil der erwärmten Trockenluft ungenutzt aus der Geschirrspülvorrichtung entweicht. Die gezielte, zwangsgeführte Zirkulation des Trocknungsluftstromes führt dazu, daß etwa zwei Drittel der gesamten Trocknungsluft umgewälzt werden, indem diese durch den Lufteinlaß 18 dem Gebläse 16 zugeführt werden. Um insbesondere im Bereich des Lufteinlasses 18 die Verlustströme an warmer Luft gering zu halten, ist in diesem Bereich ein geeignetes Abdeckelement 42, zum Beispiel in Form eines Vorhanges, am offenen Austritt aus der Trocknungseinrichtung 10 angeordnet.As shown in Fig. 1, the second ones Air outlet nozzles 36 in the shaped bodies 38a and 38b Geometry that exits air at an angle to the direction of movement of the crockery and / or tablet parts the conveyor belt 14 generated. During the movement A arranged in front of the intermediate channels 28, a molded body 38b Air outlet direction at an angle to the vertical to the direction of movement A of the conveyor belt 14, has the other molded body 38a in the illustrated Embodiment nozzles that both at an angle in Direction of movement as well as against the Direction of movement of the conveyor belt are arranged. The Angle α to the vertical is between 5 degrees and 30 degrees and preferably at about 15 degrees. Since the in Fig. 1, broken line of exit from the Drying device 10 and thus the entire Continuous dishwashing device is located by the targeted exit of the drying air in the direction of arrow C. the second air outlet 36 ensures that only one small proportion of the heated dry air unused from the Dishwasher escapes. The targeted, forced circulation of the drying air flow leads that about two thirds of the total drying air are circulated by this through the air inlet 18 to the Blower 16 are supplied. In particular in the area of Air inlets 18 the leakage currents in warm air to little hold is a suitable cover element 42 in this area, for example in the form of a curtain, at the open outlet arranged the drying device 10.

Weil eine zu hohe Zirkulationsrate die Beladungsfähigkeit der Trockenluft mit Feuchte zu stark verringern würde, wird ein Teilluftstrom D gezielt aus der Trocknungseinrichtung 10 abgeführt und vorzugsweise unter Ausnutzung des Wärmeinhaltes durch das Durchlaufen eines Wärmetauschers von der Durchlaufgeschirrspülvorrichtung abgezogen.Because too high a circulation rate the loading capacity of the Dry air with moisture would decrease too much, will Partial air flow D selectively from the drying device 10 dissipated and preferably using the heat content by going through a heat exchanger from the Continuous dishwasher removed.

Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung liegt darin, daß sowohl die aus den ersten Luftaustrittsdüsen 24 austretende Trocknungsluft als auch die aus den zweiten Luftaustrittsdüsen 36 abgegebene Trocknungsluft jeweils unter Verwendung gezielter Umlenkvorrichtungen nach oben, vorzugsweise sogar in einem geeigneten Winkel zur Bewegungsrichtung des Transportbandes abgegeben werden, um die Wärmeverluste durch Trocknungsluft, die aus der Vorrichtung 10 in die Umgebung austritt, möglichst gering zu halten.Another advantage of the device according to the invention is that both from the first air outlet nozzles 24 emerging drying air as well as that from the second Air outlet nozzles 36 drying air each below Use of targeted deflection devices upwards, preferably even at a suitable angle to the Direction of movement of the conveyor belt are given to the Heat losses due to drying air coming from the device 10 leaks into the environment to keep as low as possible.
