Description

Die Erfindung bezieht sich auf eine Einrichtung zum Trocknen von Geschirr in einer Haushalt-Geschirrspülmaschine oder dergl., in der die Spülflotte durch einen außerhalb eines Spülbehälters angeordneten Erhitzer, vorzugsweise einen elektrischen Durchlauferhitzer, aufgeheizt wird, unter Verwendung eines weitgehend geschlossenen Trockensystems, bei dem Luft aus dem Spülbehälter über eine durch Aufheizung regenerierbare Trockenvorrichtung und von dieser zurück in den Spülbehälter zirkuliert.The invention relates to a device for drying dishes in a household dishwasher or the like., In which the washing liquor is heated by a heater arranged outside a washing container, preferably an electric instantaneous water heater, using a largely closed drying system, in which air from the rinsing tank via a drying device that can be regenerated by heating and from there circulates back into the rinsing tank.

Das in einen Geschirrspüler eingelegte Geschirr wird nach Abschluß des Reinigungsvorganges in einem sog. Klarspülgang durch die umgewälzte Spülflotte auf ca. 60°C bis 70°C aufgeheizt. Nach Abschluß dieses Heizvorganges wird Klarspülmittel zugefügt und auf dem Geschirr verteilt. Danach wird die heiße Spülflotte abgepumpt und damit der Trockenvorgang eingeleitet. Im allgemeinen sind die Wandungen des Geschirrspülers etwas kühler als das gespülte Geschirr, so daß Wasser an diesen Wandungen auskondensiert und damit vom Geschirr abdunstet.After the cleaning process has been completed, the dishes placed in a dishwasher are heated to about 60 ° C. to 70 ° C. in a so-called rinse cycle through the circulated washing liquor. After this heating process is completed, rinse aid is added and spread over the dishes. The hot washing liquor is then pumped out and the drying process is initiated. In general, the walls of the dishwasher are somewhat cooler than the washed dishes, so that water condenses on these walls and thus evaporates from the dishes.

Nicht in allen Fällen erfolgt bei dieser Art der Trocknung der Trockenvorgang gleichmäßig und nicht in allen Fällen rasch genug. Insbesondere bei Geschirr mit geringer Wärmekapazität bleiben häufig Tropfen haften, die nicht nur zu unschönen Flecken, sondern auch zu Korrosionen Anlaß geben können. Man hat deshalb versucht, den Trockenvorgang zu verbessern. So kann durch Kühlung eines Wandungsteiles mit einer Wasser-Berieselungseinrichtung der Niederschlag an dieser gekühlten Fläche wesentlich verbessert werden. Auch durch Umwälzen der Luft, z.B. über eine in den Behälter eingelassene Kaltwasserfläche, kann der Trockenvorgang ebenso verbessert werden, wie durch das Umwälzen der Luft über außerhalb des Spülbehalters angeordnete Trockeneinrichtungen. Auch das Auslassen der mit Wasserdampf gesättigten Luft aus dem Behälter fördert die Trocknung, hat jedoch den Nachteil, daß die Feuchtigkeit an die umliegenden Möbel und in die Räume gelangt.Not in all cases with this type of drying does the drying process take place evenly and not in all cases quickly enough. Especially with dishes with low heat capacity drops often stick, which can give rise not only to unsightly stains but also to corrosion. An attempt has therefore been made to improve the drying process. Thus, by cooling a wall part with a water sprinkler, the precipitation on this cooled surface can be significantly improved. Also by circulating the air, for example via a cold water surface let into the container, the drying process can be improved as well as by circulating the air via drying devices arranged outside the rinsing container. Exhausting the air saturated with water vapor from the container promotes drying, but has the disadvantage that the moisture gets to the surrounding furniture and into the rooms.

Zur Vermeidung der zuletzt genannten Nachteile bevorzugt man geschlossene Systeme. Hier wurde auch schon vorgeschlagen, Latentwärmespeicher einzusetzen, durch die die mit Wasserdampf gesättigte Luft gekühlt und damit entfeuchtet wird.To avoid the disadvantages mentioned last, closed systems are preferred. It has already been proposed here to use latent heat stores, by means of which the air saturated with water vapor is cooled and thus dehumidified.

In der den nächstkommenden Stand der Technik bildenden DE-OS 20 16 831 ist eine Geschirrspülmaschine beschrieben, bei der an eine Wand des Spülbehälters ein mit dessen Innenraum durch eine verschließbare Öffnung verbundener Behälter zur Aufnahme eines Trocknungsmittels angebaut ist, das Feuchtigkeit aufzunehmen und bei Erhitzung wieder abzugeben vermag. Diese bekannte Ausführungsform hat den Nachteil, daß zum einen der Behälter mit dem Trocknungsmittel nur schwer gegenüber dem Innenraum des Spülbehälters abzutrennen ist und zum anderen eine Zusatzheizung erforderlich ist, die zum richtigen Zeitpunkt eingeschaltet sein muß, damit beim Abschluß des Klarspülvorganges das Trocknungsmittel ausreichend getrocknet ist.DE-OS 20 16 831, which forms the closest prior art, describes a dishwasher in which, on a wall of the washing compartment, a container for receiving a drying agent, which is connected to the interior thereof through a closable opening, is built in, to absorb the moisture and to heat it again when heated can deliver. This known embodiment has the disadvantage that, on the one hand, the container with the drying agent is difficult to separate from the interior of the washing container and, on the other hand, additional heating is required, which must be switched on at the right time so that the drying agent is sufficiently dried when the rinsing process is completed .

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Trocknen von Geschirr zu schaffen, bei der der Trockenvorgang rasch und ohne besonderen zusätzlichen Aufwand durchgeführt wird. Gemäß der Erfindung wird dies bei einer Einrichtung der eingangs genannten Art dadurch erreicht, daß die Trockenvorrichtung aus einem mit dem Erhitzer in Wärmekontakt stehenden Trockenbehälter besteht.The invention has for its object to provide a device for drying dishes, in which the drying process is carried out quickly and without any special additional effort. According to the invention, this is achieved in a device of the type mentioned at the outset in that the drying device consists of a drying container which is in thermal contact with the heater.

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. Im einfachsten Fall kann der Trockenbehälter mit Steinen aus Ton oder dergl. gefüllt sein, wie sie z.B. bei Hydrokulturen Verwendung finden. Bessere Eigenschaften, d.h. eine höhere Feuchtigkeitsaufnahme bei geringerem Volumen, haben Trockenmittel, die mit ihren molekularen Strukturen Feuchtigkeit adsorbieren. Vorzugsweise werden als Trockenmittel Zeolithe eingesetzt, wie sie im Chemie-Lexikon von Römpp 1977 beschrieben sind. Damit das Trockenmittel gut handhabbar ist, ist es vorteilhaft, ein granulatartiges Schüttgut zu verwenden. Die Verbindung des Trockenbehälters mit dem Spülbehälter erfolgt zweckmäßig über Luftführungen, in die auch ein Gebläse eingebaut sein kann.By connecting the drying container to the heater, which is in any case available for heating the washing liquor, the drying device is immediately ready for operation after the washing process has ended. In the simplest case, the drying container can be filled with stones made of clay or the like, e.g. used in hydroponics. Better properties, i.e. Desiccants which absorb moisture with their molecular structures have a higher moisture absorption at a lower volume. Zeolites such as are described in the Römpp chemistry lexicon 1977 are preferably used as drying agents. In order for the desiccant to be easy to handle, it is advantageous to use a granular bulk material. The connection between the drying container and the rinsing container is expediently carried out via air ducts in which a blower can also be installed.

Wird das Trockenmittel zumindest teilweise als Mantel um die Heizelemente des Erhitzers gelegt, dann ersetzen diese Teile die an sich sonst übliche thermische Abschirmfläche. Die Heizelemente erreichen Oberflächentemperaturen bis 250°C, so daß die Trockenmittel im Trockenbehälter während jedes Aufheizvorganges sicher aufgeheizt und damit getrocknet werden. Eine besonders gute konstruktive Durchbildung sieht einen Trockenbehälter vor, der als doppelwandiger Hohlzylinder ausgeformt und so um die Heizung des Durchlauferhitzers gelegt ist. Der Trockenbehälter kann aus Gründen einfacher Montage auch aus zwei Halbschalen bestehen. Die Ein- und Auslaßöffnungen des Behälters können diagonal gegenüberliegend angeordnet sein, damit sich eine gleichmäßige Durchströmung des Trockenbehälters ergibt. Wärmebrücken, die ggf. auch als Luftleitflächen ausgebildet sind, können im Trockenbehälter die Abscheidung der Feuchtigkeit aus der Luft verbessern.If the desiccant is at least partially placed as a jacket around the heating elements of the heater, then these parts replace the otherwise usual thermal shielding surface. The heating elements reach surface temperatures of up to 250 ° C, so that the desiccants in the drying container are safely heated during each heating process and thus dried. A particularly good constructive design provides for a drying container which is shaped as a double-walled hollow cylinder and is thus placed around the heater of the instantaneous water heater. For reasons of simple assembly, the drying container can also consist of two half-shells. The inlet and outlet openings of the container can be arranged diagonally opposite one another, so that there is a uniform flow through the drying container. Thermal bridges, which may also be designed as air guiding surfaces, can improve the separation of moisture from the air in the drying container.

Da die Luftführungen im Spülbehälter zweckmäßig einerseits oben und andererseits im unteren Teil des Spülbehälters münden und die Luftfeuchtigkeit während des Spülvorganges aus dem Trockner ferngehalten werden soll, ist es vorteilhaft, die Luftführung mit einem Verschluß zu versehen, der während des Spülens die Luftzirkulation unterbricht. Ist ein Gebläse für die Luftzirkulation vorgesehen, so kann die bodenseitig vorgesehene Ausblasöffnung mit einem durch den Luftstrom abhebbaren Verschluß versehen werden, der z.B. kappenartig die Auslaßöffnung abdeckt.Since the air ducts in the washing compartment expediently open on the one hand at the top and on the other hand in the lower part of the washing compartment and the air humidity is to be kept away from the dryer during the washing process, it is advantageous to provide the air duct with a closure which interrupts the air circulation during washing. If a blower is provided for the air circulation, the outlet opening provided on the bottom can be provided with a closure which can be lifted off by the air flow and which, e.g. covers the outlet opening in a cap-like manner.

Anhand der Zeichnung sei ein Ausführungsbeispiel der Erfindung beschrieben. Es zeigen:

  • Fig. 1 in schematischer Darstellung einen Geschirrspüler mit der Einrichtung nach der Erfindung und
  • Fig. 2 in schematischer Darstellung die Ausbildung und Zuordnung des Trockenbehälters zum Durchlauferhitzer.
An embodiment of the invention will be described with reference to the drawing. Show it:
  • Fig. 1 shows a schematic representation of a dishwasher with the device according to the invention and
  • Fig. 2 shows a schematic representation of the design and assignment of the drying container to the water heater.

Ein Spülbehälter 1 ist bodenseitig mit einem Sumpf 2 ausgestattet, von dem aus die Spülflotte über den Durchlauferhitzer 3 von einer Pumpe 4 in das nicht gezeichnete Verteiler- und Sprühsystem des Spülers gedrückt wird. Um den Durchlauferhitzer 3, bestehend aus dem Durchflußrohr 5 und dem Rohrheizkörper 6, ist ein doppelwandiger Hohlzylinder 7 als Trockenbehälter gelegt, der mit einem Trockenmittel gefüllt ist. Über den Anschluß 8 ist der Trockenbehälter 7 mit einer im Behälter 1 mündenden Ausblasöffnung 9 verbunden, die mit einer kappenartigen Abdeckung 10 versehen ist. Über den Anschluß 11 ist der Trockenbehälter 7 mit der Luftführung 12 verbunden, in die ein Gebläse 13 eingeschleift ist. Die Öffnung 14 der Luftführung 12 endet deckseitig im Spülbehälter 1.A rinsing container 1 is equipped on the bottom side with a sump 2, from which the rinsing liquor is pressed by a pump 4 into the distribution and spray system (not shown) of the rinser via the flow heater 3. Around the instantaneous water heater 3, consisting of the flow tube 5 and the tubular heater 6, a double-walled hollow cylinder 7 is placed as a drying container, which is filled with a drying agent. Via the connection 8, the drying container 7 is connected to a discharge opening 9 which opens into the container 1 and is provided with a cap-like cover 10. Via the connection 11, the drying container 7 is connected to the air duct 12, into which a fan 13 is looped. The opening 14 of the air duct 12 ends on the top side in the washing compartment 1.

Nach Abschluß eines Aufheizvorganges, bei dem der Rohrheizkörper 6 auch den Trockenbehälter 7 auf Temperaturen von z.B. mehr als 100°C aufheizt, wird die Spülflotte durch eine nicht gezeichnete Abwasserpumpe aus dem Behälter 1 entfernt. Wird nun das Gebläse 13 eingeschaltet, so wird die stark feuchtigkeitshaltige Luft aus dem Spülbehalter über die Öffnung 14 abgesaugt und durch das Gebläse 13 in den Trockenbehälter 7 gedrückt. Das im Trockenbehälter 7 gelagerte Trockenmittel nimmt die Feuchtigkeit auf und die vergleichsweise trockene Luft wird über den Anschluß 8 und die Ausblasöffnung 9 in den Behälter 1 zurückgedrückt. Die Luft nimmt hier erneut Feuchtigkeit auf und gibt sie im Kreislauf an das Trockenmittel wieder ab.After completing a heating process, in which the tubular heater 6 also the drying container 7 to temperatures of e.g. heats up more than 100 ° C, the washing liquor is removed from the tank 1 by a sewage pump, not shown. If the fan 13 is now switched on, the highly moisture-containing air is sucked out of the rinsing container through the opening 14 and pressed into the drying container 7 by the fan 13. The desiccant stored in the drying container 7 absorbs the moisture and the comparatively dry air is pressed back into the container 1 via the connection 8 and the blow-out opening 9. The air again absorbs moisture here and releases it back into the desiccant.

Mit einer Einrichtung nach der Erfindung wird bei geringem Aufwand erreicht, daß der Trockenvorgang ohne Beeinträchtigung der Umgebung rasch zum Abschluß gebracht werden kann.With a device according to the invention it is achieved with little effort that the drying process can be brought to a conclusion quickly without impairing the environment.

Bei der nächsten Inbetriebnahme des Geschirrspülers wird schon im Spülgang, also beim Aufheizen der Reinigungsflotte, das Trockenmittel im Trockenbehälter wieder aufgeheizt und dabei die Feuchtigkeit über die Luftführung in den Spülbehälter zurückgeführt.The next time the dishwasher is started up, the desiccant in the drying container is heated up again in the wash cycle, i.e. when the cleaning liquor is heated up, and the moisture is returned to the washing container through the air duct.

Zur besseren Wärmeverteilung und auch zur gleichmäßigeren Abscheidung der Feuchtigkeit können in den doppelwandigen Hohlkörper Wärmebrücken und Luftleitflächen eingesetzt sein.For better heat distribution and also for more uniform separation of moisture, thermal bridges and air guiding surfaces can be used in the double-walled hollow body.
