Definitions
- the invention relates to a dishwasher with a rinsing container and devices for rinsing dishes by means of rinsing liquor and with a Sorptionstrockenvorraum which is air-conductively connected to the rinse tank by circulating air and has a heater and a sorbent column with reversibly dehydratable material, wherein the sorbent in a housing with an air inlet and an air outlet is arranged.

- the drying device consists of a heater in thermal contact with the heater
- Dry container which is filled with a moisture adsorbing desiccant.
- a moisture adsorbing desiccant By connecting the drying container with the heating of the rinsing liquor Any existing heater results in the immediate operation of the dryer after the flushing process.
- the desiccant is hereby placed at least partly as a jacket around the heating elements of the heater, so that the desiccant can be heated in the drying container during each heating process and thus dried.
- the drying container is formed as a double-walled hollow cylinder in which the dry material is stored.
- the arrangement of the inlet and outlet ports for connection to the closed air system takes place in a diagonally opposite arrangement. This results in the disadvantage of a relatively high flow resistance, so that the fan provided for the promotion of the air flow must be operated with very high power. This is negative in terms of noise and energy consumption noticeable.
- the desorption is time consuming and can also lead to local overheating of the desiccant and thus to its irreversible damage.
- the desorption is also difficult because the heater is located in the center of the double-walled hollow cylinder and a radial propagation of the heat to the desiccant close to the outer hollow cylinder wall is hardly possible due to the axially flowing air flow.
- the object of the present invention is therefore to provide a dishwasher, in which the dry material contained in a Sorptionstrockenvorraum is evenly heated for the purpose of desorption.
- the sorption column is arranged in a housing with an air inlet and an air outlet, wherein the heater is arranged in the flow direction of the air in front of the air inlet , As a result, evenly heated air is introduced into the sorption column.
- the advantage of this procedure is that the air is heated at the inlet of the sorption column, preferably outside of it, whereby this uniformly hot air is supplied and this hot air is passed through the sorption column. Overheating of the reversibly dehydratable material of the sorption column during desorption is excluded. This is especially true when the heater is located outside the housing.
- the housing has a base area having the air inlet and a cover area having the air outlet. This advantageously ensures a low flow resistance within the sorption column, since the air can be conducted "straight" through the housing of the sorption column.
- the base surface and / or the top surface are at least partially formed as a sieve, so that the air inlet and / or the air outlet is or are formed by the sieve surface.
- the flow resistance of the air stream guided through the sorption column can be kept low as a result.
- the heater and the air inlet are arranged at least partially overlapping.

This makes it possible to integrally form the fan housing and the housing of the sorption column, so that an overall compact unit is provided, which takes up only a small space in the dishwasher.

- the content of the applications DE 10353774 and / or DE 1035375 is thus included, as far as appropriate, in this application.

- the sorption column is, as explained above, used both for drying and for heating air conducted through.
- FIG. 1 shows a first exemplary embodiment, which represents the sorption drying device 1 in a sectional side view (FIG. 1 a) and a view from below (FIG. 1 b).
- the sorption drying apparatus 1 has a radial fan 2 with a propeller 11 in a housing 8, via whose inlet 12 air is drawn in, compressed and fed to the sorption column 3 via a heater 6 designed as a wire heater.
- the sorption column 3 is formed in a housing 9 which has a cylindrical shape.
- a wall 10, also referred to as housing jacket, is provided with an insulation, which may be formed for example in the form of a thermal insulation or a double wall with or without vacuum.
- the base 6 facing the heater 6 forms an inlet 13 of the sorption column 3, which is preferably designed as a sieve for fixing the reversibly dehydratable material 4 of the sorption column 3 arranged in the housing 9. While the air inlet 13 extends over the entire base area in the exemplary embodiment, an air outlet 7 of the sorption column, arranged in the center of the base area, takes by way of example only a small area section. Due to the size of the air outlet 7, on the one hand, the flow resistance of the passed through the sorption column 3 Air and their exit velocity set in the washing. The airway is indicated by the arrows A, B and C.
- the heater 6 designed as a wire heater is arranged at least partially with the air inlet 13 overlapping outside of the air inlet of the sorption column. Contrary to the drawing, the wire heater could be formed completely overlapping below the air inlet 13. How big the wire heater is made and which part of the air intake covers it depends essentially on the power dissipated by the wire heater. Due to the outside, but in close proximity to the air inlet 13, arranged heater 6, there is the effect that the air routed through the heater away until the entry into the Sorptioskolonne 3 can not or at least not significantly cool, so that an effective heat and Desorption of reversibly dehydratable material is ensured. On the other hand - with possibly too high power output of the heater - no local overheating of reversibly dehydratable material occur.
- the flow resistance of the air passed through it is determined by the diameter of the spherical reversibly dehydratable material 4.
- the diameter of the reversibly dehydratable material a tradeoff must be made between the desired surface area of this material and the resulting direct flow resistance. It has proved to be advantageous spherical formed reversibly dehydratable material with a diameter of 2.5 to 5 mm.

- the heating is predominantly formed as a tubular heater (for example in the form of a wire or belt heater), which now extends over the entire surface of the air inlet 13.
- Disadvantage of a tubular heater is the need for a very high heat output or a very high fan speed. Should the Sorptionstrockenvoriques be used simultaneously for heating treatment liquid in the interior of the washing by hot air or hot steam is introduced into the washing, this type of heating is optionally not suitable for reasons of time.

Description
Geschirrspülmaschine mit einer Sorptionstrockenvorrichtung Dishwasher with a Sorptionstrockenvorrichtung
Die Erfindung betrifft eine Geschirrspülmaschine mit einem Spülbehälter und Vorrichtungen zum Spülen von Geschirr mittels Spülflotte sowie mit einer Sorptionstrockenvorrichtung, die mit dem Spülbehälter durch umgewälzte Luft luftleitend verbunden ist und eine Heizung sowie eine Sorptionskolonne mit reversibel dehydrierbarem Material aufweist, wobei die Sorptionskolonne in einem Gehäuse mit einem Lufteinlass und einem Luftauslass angeordnet ist.The invention relates to a dishwasher with a rinsing container and devices for rinsing dishes by means of rinsing liquor and with a Sorptionstrockenvorrichtung which is air-conductively connected to the rinse tank by circulating air and has a heater and a sorbent column with reversibly dehydratable material, wherein the sorbent in a housing with an air inlet and an air outlet is arranged.
Gemäß der DE 103 53 774 und/oder der DE 103 53 775 der Anmelderin wird reversibel dehydrierbare Material zur Desorption auf sehr hohe Temperaturen erhitzt. Dabei tritt die in diesem gespeicherte Flüssigkeit als heißer Wasserdampf aus. Durch die Leitung vonAccording to DE 103 53 774 and / or DE 103 53 775 of the Applicant, reversibly dehydratable material is heated to very high temperatures for desorption. The stored liquid in this case exits as hot water vapor. Through the management of

Geschirr ausreichend zu erwärmen. Damit kann gegebenenfalls auf eine weitere Heizung weitgehend verzichtet werden, und die zur Desorption eingesetzte Energie kann bis auf die Energie, die zur Überwindung der Bindungskräfte zwischen Wasser und reversibel dehydrierbarem Material benötigt wird, nahezu vollständig zur Erwärmung der Spülflotte und/oder des Geschirrs verwendet werden. Neben einer Energieeinsparung ist damit eine effiziente Reinigung des Spülguts gewährleistet.To heat dishes sufficiently. Thus, if necessary, can be largely dispensed with a further heating, and the energy used for desorption can be almost completely used for heating the rinsing liquor and / or the dishes except for the energy needed to overcome the binding forces between water and reversibly dehydratable material , In addition to energy savings, this ensures efficient cleaning of the items to be washed.
Aus der EP 0 358 279 B1 ist eine Einrichtung zum Trocknen von Geschirr in einer Haushalts-Geschirrspülmaschine bekannt, in der die Spülflotte durch einen außerhalb desEP 0 358 279 B1 discloses a device for drying dishes in a domestic dishwasher, in which the rinsing liquor is conveyed through an outside of the dishwasher

Trocknungsvorrichtung und von dieser zurück in den Spülbehälter zirkuliert. Dabei besteht die Trocknungsvorrichtung aus einem mit dem Erhitzer in Wärmekontakt stehendenDrying device and circulated from this back into the washing. In this case, the drying device consists of a heater in thermal contact with the heater
Trockenbehälter, welcher mit einem die Feuchtigkeit adsorbierenden Trockenmittel gefüllt ist. Durch die Verbindung des Trockenbehälters mit dem für die Aufheizung der Spülflotte ohnehin vorhandenen Erhitzer ergibt sich nach Ablauf des Spülvorganges eine sofortige Betriebsbereitschaft der Trockenvorrichtung. Das Trockenmittel wird hierbei zumindest teilweise als Mantel um die Heizelemente des Erhitzers gelegt, so dass das Trockenmittel im Trockenbehälter während jedes Aufheizvorganges aufgeheizt und damit getrocknet werden kann.Dry container, which is filled with a moisture adsorbing desiccant. By connecting the drying container with the heating of the rinsing liquor Any existing heater results in the immediate operation of the dryer after the flushing process. The desiccant is hereby placed at least partly as a jacket around the heating elements of the heater, so that the desiccant can be heated in the drying container during each heating process and thus dried.
Der Trockenbehälter ist als doppelwandiger Hohlzylinder ausgeformt, in welchen das Trocken material eingelagert ist. Die Anordnung der Einlass- und Auslassöffnung zum Anschluss an das geschlossene Luftsystem erfolgt in diagonal gegenüberliegender Anordnung. Hieraus ergibt sich der Nachteil eines verhältnismäßig hohen Strömungswiderstands, so dass das zur Förderung des Luftstroms vorgesehene Gebläse mit sehr hoher Leistung betrieben werden muss. Dies macht sich negativ hinsichtlich der Geräuschentwicklung und hinsichtlich des Energieverbrauchs bemerkbar.The drying container is formed as a double-walled hollow cylinder in which the dry material is stored. The arrangement of the inlet and outlet ports for connection to the closed air system takes place in a diagonally opposite arrangement. This results in the disadvantage of a relatively high flow resistance, so that the fan provided for the promotion of the air flow must be operated with very high power. This is negative in terms of noise and energy consumption noticeable.
Aufgrund der konstruktiven Ausgestaltung der Sorptionstrockenvorrichtung, welche eine inhomogene Wärmeeinleitung in das Trocken material bedingt, ist die Desorption zeitaufwendig und kann darüber hinaus zu lokalen Überhitzungen des Trockenmittels und damit zu dessen irreversibler Schädigung führen. Die Desorption ist auch deshalb schwierig, da der Erhitzer im Zentrum des doppelwandigen Hohlzylinders angeordnet ist und eine radiale Ausbreitung der Hitze zu dem nahe der äußeren Hohlzylinderwand gelegenen Trocknungsmittel aufgrund des axial vorbeiströmenden Luftstroms kaum möglich ist.Due to the structural design of the Sorptionstrockenvorrichtung, which causes an inhomogeneous heat input into the dry material, the desorption is time consuming and can also lead to local overheating of the desiccant and thus to its irreversible damage. The desorption is also difficult because the heater is located in the center of the double-walled hollow cylinder and a radial propagation of the heat to the desiccant close to the outer hollow cylinder wall is hardly possible due to the axially flowing air flow.
Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, eine Geschirrspülmaschine bereitzustellen, bei welcher das in einer Sorptionstrockenvorrichtung enthaltene Trocken material zum Zwecke der Desorption gleichmäßig erwärmbar ist.The object of the present invention is therefore to provide a dishwasher, in which the dry material contained in a Sorptionstrockenvorrichtung is evenly heated for the purpose of desorption.
Diese Aufgabe wird erfindungsgemäß mit einer Geschirrspülmaschine gemäß den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Patentansprüchen.This object is achieved with a dishwasher according to the features of claim 1. Advantageous embodiments will be apparent from the dependent claims.
Bei der erfindungsgemäßen Geschirrspülmaschine mit einem Spülbehälter und Vorrichtungen zum Spülen von Geschirr mittels Spülflotte sowie mit einer Sorptionstrockenvorrichtung, die mit dem Spülbehälter durch umgewälzte Luft luftleitend verbunden ist und eine Heizung sowie eine Sorptionskolonne mit reversibel dehydrierbarem Material aufweist, ist die Sorptionskolonne in einem Gehäuse mit einem Lufteinlass und einem Luftauslass angeordnet, wobei die Heizung in Strömungsrichtung der Luft vor dem Lufteinlass angeordnet ist. Dadurch wird gleichmäßig erwärmte Luft in die Sorptionskolonne eingeleitet.In the dishwasher according to the invention with a washing container and devices for rinsing dishes by means of rinsing liquor and with a Sorption drying apparatus, which is air-conductively connected to the washing container by circulating air and has a heating and a sorption column with reversibly dehydratable material, the sorption column is arranged in a housing with an air inlet and an air outlet, wherein the heater is arranged in the flow direction of the air in front of the air inlet , As a result, evenly heated air is introduced into the sorption column.
In einer bevorzugten Ausgestaltung ist die Heizung im Bereich des Lufteinlass der Sorptionskolonne, d. h. in unmittelbarer räumlicher Nähe des Lufteinlasses, angeordnet. Der Vorteil dieser Vorgehensweise besteht darin, dass die Erhitzung der Luft am Eingang der Sorptionskolonne, vorzugsweise außerhalb davon, erfolgt, wodurch dieser gleichmäßig heiße Luft zugeführt wird und diese heiße Luft durch die Sorptionskolonne durchgeleitet wird. Eine Überhitzung des reversibel dehydrierbaren Materials der Sorptionskolonne während der Desorption ist dabei ausgeschlossen. Dies gilt insbesondere dann, wenn die Heizung außerhalb des Gehäuses angeordnet ist. Aufgrund der unmittelbaren räumlichen Nähe der Heizung zu dem Lufteinlass der Sorptionskolonne ist weiterhin gewährleistet, dass die zur Erwärmung des Luftstroms aufgewendete Energie mit bestmöglichem Wirkungsgrad an das reversibel dehydrierbare Material weitergegeben werden kann, da eine Erkaltung des Luftstroms aufgrund der unmittelbaren räumlichen Nähe vermieden wird.In a preferred embodiment, the heating in the region of the air inlet of the sorption column, d. H. in the immediate vicinity of the air inlet, arranged. The advantage of this procedure is that the air is heated at the inlet of the sorption column, preferably outside of it, whereby this uniformly hot air is supplied and this hot air is passed through the sorption column. Overheating of the reversibly dehydratable material of the sorption column during desorption is excluded. This is especially true when the heater is located outside the housing. Due to the immediate spatial proximity of the heater to the air inlet of the sorption column is further ensured that the energy used to heat the air flow energy can be passed to the reversibly dehydratable material with the best possible efficiency, since a cooling of the air flow due to the immediate proximity is avoided.
In einer bevorzugten Ausgestaltung weist das Gehäuse eine den Lufteinlass aufweisende Grundfläche und eine den Luftauslass aufweisende Deckfläche auf. Hierdurch ist mit Vorteil ein geringer Strömungswiderstand innerhalb der Sorptionskolonne gewährleistet, da die Luft „gerade" durch das Gehäuse der Sorptionskolonne leitbar ist.In a preferred embodiment, the housing has a base area having the air inlet and a cover area having the air outlet. This advantageously ensures a low flow resistance within the sorption column, since the air can be conducted "straight" through the housing of the sorption column.
In einer weiteren zweckmäßigen Ausgestaltung sind die Grundfläche und/oder die Deckfläche zumindest bereichsweise als Sieb ausgebildet, so dass der Lufteinlass und/oder der Luftauslass durch die Siebfläche gebildet ist bzw. sind. Neben einer Fixierung des reversibel dehydrierbaren Materials innerhalb der Sorptionskolonne kann hierdurch der Strömungswiderstand des durch die Sorptionskolonne geleiteten Luftstromes gering gehalten werden. - A -In a further expedient embodiment, the base surface and / or the top surface are at least partially formed as a sieve, so that the air inlet and / or the air outlet is or are formed by the sieve surface. In addition to a fixation of the reversibly dehydratable material within the sorption column, the flow resistance of the air stream guided through the sorption column can be kept low as a result. - A -
In einer weiteren zweckmäßigen Ausgestaltung sind die Heizung und der Lufteinlass sich zumindest teilweise überdeckend angeordnet. Der Überdeckungsgrad zwischen Heizung und Lufteinlass des Gehäuses der Sorptionskolonne wird dabei im wesentlichen durch die Bauart sowie die von einer Heizung zur Verfügung stellbare Leistung bestimmt.In a further expedient embodiment, the heater and the air inlet are arranged at least partially overlapping. The degree of overlap between the heater and the air inlet of the housing of the sorption column is determined essentially by the type and the power available from a heater.
Es kann gemäß einer anderen Ausgestaltung vorgesehen sein, die Heizung in unmittelbarer räumlicher Nähe zu dem Lufteinlass der Sorptionskolonne im Inneren des Gehäuses der Sorptionskolonne anzuordnen. Zur Vermeidung von lokalen Überhitzungen ist es hierbei vorteilhaft, die Heizung mit einer möglichst großen Oberfläche innerhalb der Sorptionskolonne anzuordnen, wobei die spezifische Leistung pro Fläche derart gering bemessen werden kann, dass lokale Überhitzungen an dem reversibel dehydrierbaren Material nicht auftreten können.It may be provided according to another embodiment, to arrange the heater in the immediate vicinity of the air inlet of the sorption column inside the housing of the sorption column. To avoid local overheating, it is advantageous in this case to arrange the heater with the largest possible surface area within the sorption column, wherein the specific power per area can be dimensioned so small that local overheating of the reversibly dehydratable material can not occur.
In einer weiteren zweckmäßigen Ausgestaltung weist das Gehäuse einen wärmeisoliert ausgebildeten Gehäusemantel auf. Dieser kann beispielsweise durch eine doppelte Wandung ausgebildet sein. Alternativ oder zusätzlich kann auf die Außenseite des Gehäusemantels beispielsweise eine Wärmedämmung aufgebracht sein. Weiterhin ist denkbar, in dem zwischen der Doppelwandung entstandenen Zwischenraum ein Vakuum auszubilden, um eine möglichst gute Isolation nach außen zu erhalten. Durch das Vorsehen einer Wärmeisolierung auf dem Gehäusemantel, welcher bevorzugt den größten Teil der Oberfläche der Sorptionskolonne ausbildet, ist sichergestellt, dass die durch die Heizung aufgewendete Energie bestmöglich zur Desorption des reversibel dehydrierbaren Materials verwendet werden kann.In a further expedient embodiment, the housing has a heat-insulated housing jacket. This can be formed for example by a double wall. Alternatively or additionally, for example, a heat insulation may be applied to the outside of the housing shell. Furthermore, it is conceivable to form a vacuum in the gap formed between the double wall in order to obtain the best possible insulation to the outside. By providing a heat insulation on the housing shell, which preferably forms the largest part of the surface of the sorption column, it is ensured that the energy expended by the heating can be used as best as possible for the desorption of the reversibly dehydratable material.
In einer weiteren zweckmäßigen Ausgestaltung ist die Höhe des Gehäusemantels kleiner als die Breite oder der Durchmesser von Grund- und Deckfläche. Allgemein ausgedrückt bedeutet dies, dass die von der Luftströmung zu durchströmende Länge geringer ist als die größte Breite oder der Durchmesser von Grund- und Deckfläche. Hierdurch ergibt sich mit Vorteil ein geringer Strömungswiderstand, so dass die Leistung des Gebläses bzw. die Drehzahl des Gebläses gering ausgelegt werden kann. Eine besonders bevorzugte Anordnung ist hierbei eine zylindrische Ausbildung des Gehäuses der Sorptionskolonne, da mit dieser geometrischen Form eine besonders homogene Durchströmung desIn a further expedient embodiment, the height of the housing shell is smaller than the width or the diameter of the base and top surfaces. Generally speaking, this means that the length to be flowed through by the air flow is less than the maximum width or the diameter of the base and top surfaces. This results in advantage with a low flow resistance, so that the performance of the fan or the speed of the fan can be made low. A particularly preferred arrangement here is a cylindrical configuration of the housing of the sorption column, since with this geometric shape a particularly homogeneous flow through the
Luftstroms gewährleistet ist. In einer weiteren zweckmäßigen Ausgestaltung weist die Sorptionstrockenvorrichtung ein Gebläse mit einem Gebläsegehäuse zur Erzeugung eines Luftstroms auf, welches in räumlicher Nähe vor dem Lufteinlass des Gehäuses der Sorptionskolonne angeordnet ist. Hierdurch ist es möglich, Gebläsegehäuse und das Gehäuse der Sorptionskolonne integral auszubilden, so dass eine insgesamt kompakte Einheit bereitgestellt wird, welche in der Geschirrspülmaschine einen nur geringen Platz beansprucht.Air flow is guaranteed. In a further expedient embodiment, the sorption drying device has a fan with a fan housing for generating an air flow, which is arranged in spatial proximity in front of the air inlet of the housing of the sorption column. This makes it possible to integrally form the fan housing and the housing of the sorption column, so that an overall compact unit is provided, which takes up only a small space in the dishwasher.
In einer Variante kann das Gebläse als Axialgebläse vor dem Einlass des Gehäuses der Sorptionskolonne angeordnet sein. In einer anderen Variante ist das Gebläse als Radialgebläse seitlich des Einlasses des Gehäuses der Sorptionskolonne angeordnet. Welche Variante bevorzugt zu wählen ist, ergibt sich im wesentlichen aus der räumlichen Anordnung der Sorptionstrockenvorrichtung in der Geschirrspülmaschine und den dabei herrschenden Platzverhältnissen.In a variant, the blower can be arranged as an axial blower in front of the inlet of the housing of the sorption column. In another variant, the fan is arranged as a radial fan laterally of the inlet of the housing of the sorption column. Which variant is preferable to choose, results essentially from the spatial arrangement of the Sorptionstrockenvorrichtung in the dishwasher and the prevailing space conditions.
Die zur Desorption eingesetzte Heizung kann als Drahtheizung, als Rohrheizkörper, als Keramikheizung oder in PTC-Technologie ausgebildet sein.The heater used for desorption can be designed as a wire heater, as a tubular heater, as a ceramic heater or in PTC technology.
In einer vorteilhaften Ausgestaltung ist die Heizung dabei in das Gebläsegehäuse integriert. Dies lässt sich vor allem bei Verwendung einer Heizung in PTC-Technologie besonders einfach realisieren, da die Widerstandsschicht oder -schichten auf der Innenseite der Gehäusewandung aufgebracht werden können. Ein weiterer Vorteil in der Verwendung einer PTC-Heizung besteht in der einfachen Fertigung, da die Schichten durch einen Druckprozess aufgebracht werden können. Weiterhin regelt sich die Heizleistung über die in den Heizabschnitten vorherrschenden Temperaturen von selbst, so dass eine Überhitzung prinzipbedingt ausgeschlossen ist. Durch entsprechende Anordnung bzw. Verschaltung einzelner Schichtabschnitte lässt sich darüber hinaus eine Heizung mit mehreren Heizleistungen realisieren.In an advantageous embodiment, the heater is integrated into the fan housing. This can be particularly easily realized, especially when using a heater in PTC technology, since the resistance layer or layers can be applied to the inside of the housing. Another advantage of using a PTC heater is the ease of fabrication since the layers can be applied by a printing process. Furthermore, the heating power regulates itself over the prevailing temperatures in the heating sections by itself, so that overheating is inherently precluded. By appropriate arrangement or interconnection of individual layer sections, moreover, a heater with several heating powers can be realized.

B. Zeolith, aufweist. Die Sorptionskolonne wird, wie eingangs erläutert, sowohl zur Trocknung als auch zur Erwärmung durchgeleiteter Luft verwendet.Dishwasher usable Sorptionstrockenvorrichtung. A dishwasher according to the invention, not shown in detail in the figures, usually has a washing container, are arranged in the baskets for the classification of items to be washed. In all embodiments of the dishwasher according to the invention, the drying of the dishes is preferably carried out as described in DE 10353774 and / or DE 1035375 of the applicant. The content of the applications DE 10353774 and / or DE 1035375 is thus included, as far as appropriate, in this application. Furthermore, a sorption drying device 1 connected in air-conducting manner to the washing container is provided, which is connected in an air-conducting manner to the washing container and a heater 6, a blower 2 and a sorption column 3 with reversibly dehydratable material, eg. As zeolite having. The sorption column is, as explained above, used both for drying and for heating air conducted through.
In den nachfolgend näher erläuterten Figuren sind verschiedene Ausführungsbeispiele derartiger Sorptionstrockenvorrichtungen dargestellt.In the figures explained in more detail below, various embodiments of such Sorptionstrockenvorrichtungen are shown.
Figur 1 zeigt ein erstes Ausführungsbeispiel, welches die Sorptionstrockenvorrichtung 1 in einer geschnittenen Seitenansicht (Fig. 1a) sowie einer Sicht von unten (Fig. 1 b) darstellt. Die Sorptionstrockenvorrichtung 1 weist ein Radialgebläse 2 mit einem Propeller 11 in einem Gehäuse 8 auf, über dessen Einlass 12 Luft angesaugt, verdichtet und über eine als Drahtheizung ausgebildete Heizung 6 der Sorptionskolonne 3 zugeführt wird. Die Sorptionskolonne 3 ist in einem Gehäuse 9 ausgebildet, welches eine zylindrische Form aufweist. Eine Wandung 10, auch als Gehäusemantel bezeichnet, ist mit einer Isolierung versehen, die beispielsweise in Form einer Wärmedämmung oder einer doppelten Wandung mit oder ohne Vakuum ausgebildet sein kann.FIG. 1 shows a first exemplary embodiment, which represents the sorption drying device 1 in a sectional side view (FIG. 1 a) and a view from below (FIG. 1 b). The sorption drying apparatus 1 has a radial fan 2 with a propeller 11 in a housing 8, via whose inlet 12 air is drawn in, compressed and fed to the sorption column 3 via a heater 6 designed as a wire heater. The sorption column 3 is formed in a housing 9 which has a cylindrical shape. A wall 10, also referred to as housing jacket, is provided with an insulation, which may be formed for example in the form of a thermal insulation or a double wall with or without vacuum.
Die der Heizung 6 zugewandte Grundfläche bildet einen Einlass 13 der Sorptionskolonne 3 aus, welche bevorzugt als Sieb zur Fixierung des im Gehäuse 9 angeordneten reversibel dehydrierbaren Materials 4 der Sorptionskolonne 3 ausgebildet ist. Während der Lufteinlass 13 sich im Ausführungsbeispiel über die gesamte Grundfläche erstreckt, nimmt ein Luftauslass 7 der Sorptionskolonne, im Zentrum der Grundfläche angeordnet, beispielhaft nur einen kleinen Flächenabschnitt ein. Durch die Größe des Luftauslasses 7 werden einerseits der Strömungswiderstand der durch die Sorptionskolonne 3 geleiteten Luft sowie deren Austrittsgeschwindigkeit in den Spülbehälter festgelegt. Der Luftweg ist mit den Pfeilen A, B und C angedeutet.The base 6 facing the heater 6 forms an inlet 13 of the sorption column 3, which is preferably designed as a sieve for fixing the reversibly dehydratable material 4 of the sorption column 3 arranged in the housing 9. While the air inlet 13 extends over the entire base area in the exemplary embodiment, an air outlet 7 of the sorption column, arranged in the center of the base area, takes by way of example only a small area section. Due to the size of the air outlet 7, on the one hand, the flow resistance of the passed through the sorption column 3 Air and their exit velocity set in the washing. The airway is indicated by the arrows A, B and C.
Die als Drahtheizung ausgebildete Heizung 6 ist sich zumindest teilweise mit dem Lufteinlass 13 überdeckend außerhalb des Lufteinlasses der Sorptionskolonne angeordnet. Entgegen der zeichnerischen Darstellung könnte die Drahtheizung auch vollständig überdeckend unterhalb des Lufteinlasses 13 ausgebildet sein. Wie groß die Drahtheizung ausgeführt wird und welchen Teil des Lufteinlasses sie überdeckt, hängt im wesentlichen von der von der Drahtheizung abgegebenen Leistung ab. Aufgrund der außerhalb, jedoch in unmittelbarer Nähe zu dem Lufteinlass 13, angeordneten Heizung 6 ergibt sich der Effekt, dass die über die Heizung hinweg geleitete Luft bis zum Eintritt in die Sorptioskolonne 3 nicht oder zumindest nicht wesentlich erkalten kann, so dass eine effektive Wärmezufuhr und Desorption des reversibel dehydrierbaren Materials sichergestellt ist. Andererseits kann - bei gegebenenfalls zu hoher Leistungsabgabe der Heizung - auch keine lokale Überhitzung des reversibel dehydrierbaren Materials auftreten.The heater 6 designed as a wire heater is arranged at least partially with the air inlet 13 overlapping outside of the air inlet of the sorption column. Contrary to the drawing, the wire heater could be formed completely overlapping below the air inlet 13. How big the wire heater is made and which part of the air intake covers it depends essentially on the power dissipated by the wire heater. Due to the outside, but in close proximity to the air inlet 13, arranged heater 6, there is the effect that the air routed through the heater away until the entry into the Sorptioskolonne 3 can not or at least not significantly cool, so that an effective heat and Desorption of reversibly dehydratable material is ensured. On the other hand - with possibly too high power output of the heater - no local overheating of reversibly dehydratable material occur.
Neben den geometrischen Abmaßen des Gehäuses 9 der Sorptionskolonne 3 wird der Strömungswiderstand der durch diese durchgeleiteten Luft durch den Durchmesser des kugelförmigen reversibel dehydrierbaren Materials 4 festgelegt. Bei der Festlegung des Durchmessers des reversibel dehydrierbaren Materials muss eine Abwägung zwischen der gewünschten Oberfläche dieses Materials und dem unmittelbar daraus resultierenden Strömungswiderstand getroffen werden. Als vorteilhaft hat sich kugelförmig ausgebildetes reversibel dehydrierbares Material mit einem Durchmesser von 2,5 bis 5 mm erwiesen.In addition to the geometrical dimensions of the housing 9 of the sorption column 3, the flow resistance of the air passed through it is determined by the diameter of the spherical reversibly dehydratable material 4. When determining the diameter of the reversibly dehydratable material, a tradeoff must be made between the desired surface area of this material and the resulting direct flow resistance. It has proved to be advantageous spherical formed reversibly dehydratable material with a diameter of 2.5 to 5 mm.
Figur 2 zeigt ein zweites Ausführungsbeispiel einer Sorptionstrockenvorrichtung 1 zum Einsatz in einer erfindungsgemäßen Geschirrspülmaschine. Figur 2a zeigt eine geschnittene Seitenansicht, Fig. 2b eine Sicht von unten. Die relative Anordnung von Gebläsegehäuse 8, Heizung 6 und Gehäuse 9 der Sorptionskolonne entspricht dabei dem in Zusammenhang mit Fig. 1 beschriebenen Ausführungsbeispiel. Im Unterschied zum vorangegangenen Beispiel ist die Heizung vorwiegend als Rohrheizkörper ausgebildet (z.B. in Form einer Draht- oder Bandheizung), welche sich nunmehr über die gesamte Fläche des Lufteinlasses 13 erstreckt. Nachteil eines Rohrheizkörpers ist die Notwendigkeit einer sehr hohen Heizleistung bzw. einer sehr hohen Lüfterdrehzahl. Soll die Sorptionstrockenvorrichtung gleichzeitig zur Erwärmung von Behandlungsflüssigkeit im Inneren des Spülbehälters verwendet werden, indem heiße Luft bzw. heißer Wasserdampf in den Spülbehälter eingeleitet wird, so ist dieser Heizungstyp gegebenenfalls aus Zeitgründen nicht geeignet.FIG. 2 shows a second embodiment of a sorption drying device 1 for use in a dishwasher according to the invention. FIG. 2a shows a sectional side view, FIG. 2b a view from below. The relative arrangement of blower housing 8, heater 6 and housing 9 of the sorption column corresponds to the embodiment described in connection with FIG. In contrast to the previous example, the heating is predominantly formed as a tubular heater (for example in the form of a wire or belt heater), which now extends over the entire surface of the air inlet 13. Disadvantage of a tubular heater is the need for a very high heat output or a very high fan speed. Should the Sorptionstrockenvorrichtung be used simultaneously for heating treatment liquid in the interior of the washing by hot air or hot steam is introduced into the washing, this type of heating is optionally not suitable for reasons of time.
Figur 3 zeigt ein drittes Ausführungsbeispiel, dessen konstruktiver Aufbau ebenfalls dem in Zusammenhang mit Fig. 1 beschriebenen Beispiel entspricht. Figur 3a zeigt eine geschnittene Seitenansicht, Fig. 3b ein Sicht von unten. Im Unterschied hierzu ist die Heizung nunmehr als Keramikheizung (sogenannte Honeycomb-Heizung) ausgebildet, welche gegenüber einer Drahtheizung eine größere Robustheit aufweist. Ein Nachteil eines derartigen Heizungstyps ist jedoch der größere Druckverlust beim Durchströmen der Heizung 6, so dass das Gebläse 2 mit einer höheren Drehzahl betrieben werden muss.Figure 3 shows a third embodiment, the constructive structure also corresponds to the example described in connection with FIG. FIG. 3a shows a sectional side view, FIG. 3b a view from below. In contrast, the heater is now designed as a ceramic heater (so-called honeycomb heater), which has a greater robustness than a wire heater. A disadvantage of such a heating type, however, is the greater pressure loss when flowing through the heater 6, so that the blower 2 must be operated at a higher speed.
Figuren 4 und 5 zeigen weitere Ausführungsbeispiele, bei denen die Heizung im Inneren der Sorptionskolonne 3 ausgebildet ist. Zur Vermeidung einer sehr hohen Leistungsdichte erstreckt sich die Heizung bevorzugt über eine große Länge über den gesamten Innenraum der Sorptionskolonne 3. Eine derartige Ausführungsvariante hat den Vorteil, dass das Gebläse 2 sowohl als Radialgebläse (Fig. 4) als auch als Axialgebläse (Fig. 5) ausgebildet werden kann. Dabei ist es insbesondere bei der in Fig. 4 gezeigten Variante möglich, den mit dem Bezugszeichen 14 gekennzeichneten Luftkanal mit einer sehr geringen Höhe h auszuführen, wodurch sich eine kompaktere Anordnung ergibt. Die in Fig. 5 gezeigte Variante lässt sich selbstverständlich auch mit den in den vorangegangenen Ausführungsbeispielen genannten Heizungstypen realisieren, wobei gegebenenfalls ein größeres Bauvolumen in Kauf genommen werden muss.Figures 4 and 5 show further embodiments in which the heater is formed in the interior of the sorption column 3. To avoid a very high power density, the heater preferably extends over a large length over the entire interior of the sorption column 3. Such a variant has the advantage that the fan 2 both as a radial fan (Fig. 4) and as an axial fan (Fig ) can be formed. In this case, it is possible, in particular in the variant shown in FIG. 4, to carry out the air duct designated by the reference numeral 14 with a very small height h, resulting in a more compact arrangement. Of course, the variant shown in FIG. 5 can also be realized with the types of heating mentioned in the preceding exemplary embodiments, with a larger construction volume possibly having to be accepted.
In dem in Fig. 6 dargestellten sechsten Ausführungsbeispiel ist als Heizung eine PTC- Heizung dargestellt, welche im Inneren des Gehäuses 8 des Gebläses 2 angeordnet ist. So kann die PTC-Schicht beispielsweise durch einen Druckvorgang auf die Innenseite des Gehäuses 8 aufgebracht werden. Vorteil einer PTC-Heizung ist, dass sich die Heizleistung über die in der PTC-Schicht vorherrschende Temperatur von alleine regelt. In entsprechender weise kann der Luftkanal 14 sehr klein ausgebildet werden, wodurch sich ebenfalls eine kompakte Sorptionstrockenvorrichtung ergibt. Bei allen vorstehend beschriebenen Varianten ist es besonders vorteilhaft möglich, Gebläse2 , Heizung 6 und Sorptionskolonne 3 zu einer integralen Einheit auszubilden, insbesondere deren Gehäuse einstückig auszuführen. Hierdurch ist einerseits eine sehr einfache Montage der Sorptionstrockenvorrichtung in der Geschirrspülmaschine möglich, andererseits können die baulichen Abmaße gering gehalten werden.In the sixth exemplary embodiment illustrated in FIG. 6, a PTC heater, which is arranged in the interior of the housing 8 of the blower 2, is shown as the heater. For example, the PTC layer can be applied to the inside of the housing 8 by a printing process. The advantage of a PTC heater is that the heating power is controlled on its own by the temperature prevailing in the PTC layer. In a corresponding manner, the air channel 14 can be made very small, which also results in a compact Sorptionstrockenvorrichtung. In all the variants described above, it is particularly advantageous possible to form blower 2, heater 6 and sorption column 3 to form an integral unit, in particular to carry out their housing in one piece. As a result, on the one hand, a very simple installation of the sorption drying device in the dishwasher is possible, on the other hand, the structural dimensions can be kept low.
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. Weiterhin ist eine einfache Montage gewährleistet, welche einen kostengünstigen Herstellungsprozess erlaubt. 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. Furthermore, a simple assembly is guaranteed, which allows a cost-effective manufacturing process.
