A dish-washing machine, in particular for domestic use, in which a flow pipe (6) carrying a stream of washing fluid during the washing operation is coaxially disposed within a further flow pipe (12) wherein the flow pipe (12) is provided with a coaxial tubular heater (11), so that an air stream for drying the dishes, flowing through the annular space between both flow pipes (6, 12), is heated, characterized in that the flow pipes (6, 12) and the tubular heater (11) are disposed below the bottom of the container (1) receiving the dishes, in such manner that the tubular heater (11) is located within the annular space, carrying the air stream, between both flow pipes (6, 12) and also heats the flow pipe (6) carrying the stream of washing fluid.

Description

Die Erfindung betrifft eine Geschirrspülmaschine, insbesondere für den Hausgebrauch, mit einer elektrischen Heizeinrichtung zur Erhitzung der Spülflüssigkeit und zur Trocknung des Geschirrs.The invention relates to a dishwasher, in particular for domestic use, with an electrical heating device for heating the washing liquid and for drying the dishes.

Die üblichen Geschirrspülmaschinen besitzen in dem das Geschirr aufnehmenden Behälter einen Heizstab aus einem elektrischen Rohrheizkörper. Während des Spülvorganges trifft ein Teil der z. B. von Verteilerarmen abgesprühten Waschflüssigkeit auf den Rohrheizkörper, so daß diese erhitzt und der Rohrheizkörper abgekühlt wird. Diese Konstruktionen haben den Nachteil, daß Schmutz und Geschirrspülmittelreste an der Oberfläche des Rohrheizkörpers haften bleiben und eintrocknen, so daß die Wärmeabgabe des Rohrheizkörpers verschlechtert wird. Manchmal werden die Sprühstrahlen auch durch Geschirrteile abgedeckt, so daß es zu örtlichen Überhitzungen des Rohrheizkörpers kommt. Die Trocknung des Geschirrs erfolgt durch die Strahlung des Rohrheizkörpers. Der Trockenvorgang ist dementsprechend ungleichmäßig, d. h. in der Nähe des Rohrheizkörpers oder im Strahlungsbereich angeordnete Geschirrteile werden stärker erhitzt als abgedeckte Geschirrteile. Der ungleichmäßige Wärmeübergang auf die Spülflüssigkeit und auf das Geschirr beim Trockenvorgang führt zu einem erhöhten Energieverbrauch.The usual dishwashers have a heating rod made of an electric tubular heater in the container holding the dishes. During the rinsing process, part of the z. B. sprayed from distributor arms washing liquid on the tubular heater, so that it is heated and the tubular heater is cooled. These constructions have the disadvantage that dirt and detergent residues adhere to the surface of the tubular heater and dry up, so that the heat emission from the tubular heater is impaired. Sometimes the spray jets are also covered by dishes so that the tubular heater overheats locally. The dishes are dried by the radiation from the tubular heater. The drying process is accordingly uneven, ie in the vicinity of the tubular heater or dishes placed in the radiation area are heated more than covered dishes. The uneven heat transfer to the washing liquid and the dishes during the drying process leads to increased energy consumption.

Der Erfindung liegt nun die Auf gabe zugrunde, eine Geschirrspülmaschine vorzuschlagen, bei der mittels einer elektrischen Heizeinrichtung sowohl die Spülflüssigkeit als auch ein Luftstrom erhitzt wird, und zwar unter einem gleichmäßigen energiesparenden Wärmeübergang von der Heizeinrichtung auf die Spülflüssigkeit bzw. auf den Luftstrom.The invention is based on the task of proposing a dishwasher in which both the washing liquid and an air stream are heated by means of an electric heating device, with a uniform, energy-saving heat transfer from the heating device to the washing liquid or to the air stream.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1. Die Unteransprüche beschreiben bevorzugte Ausführungsformen.The solution to this problem results from the characterizing features of claim 1. The subclaims describe preferred embodiments.

Auf den Zeichnungen ist eine bevorzugte Ausführungsform des Gegenstandes der Erfindung dargestellt. Es zeigen:

  • Fig. 1 schematisch eine Schnittansicht einer bevorzugten Ausführungsform einer Geschirrspülmaschine;
  • Fig. 2 in vergrößertem Maßstab eine Schnittansicht des Bodenteiles der Geschirrspülmaschine.
A preferred embodiment of the subject matter of the invention is shown in the drawings. Show it:
  • 1 schematically shows a sectional view of a preferred embodiment of a dishwasher;
  • Fig. 2 is an enlarged sectional view of the bottom part of the dishwasher.

Eine Geschirrspülmaschine besitzt in üblicher Weise ein Gehäuse 1 mit im allgemeinen ausfahrbaren Körben 2, welche der Aufnahme des Geschirrs 3 dienen. Ein Sammelsumpf 4 dient zum Sammeln der ablaufenden Spülflüssigkeit, welche von einer Pumpe 5 über ein Rohr 6 einem unteren Verteilerarm 7 und einem oberen Verteilerarm 8 zugeleitet wird. Die Verteilerarme 7 und 8 sind an einem Rohrstück 9 befestigt.A dishwasher has in the usual way a housing 1 with generally extendable baskets 2, which serve to hold the dishes 3. A collecting sump 4 is used to collect the outflowing rinsing liquid, which is supplied by a pump 5 via a pipe 6, a lower distributor arm 7 and an upper Ver divider arm 8 is fed. The distributor arms 7 and 8 are attached to a pipe section 9.

Auf dem Rohrstück 6 sind drei Rohrheizkörper 11 angeordnet, und zwar sind die Rohrheizkörper 11 wendelförmig um das Rohrstück 6 herumgebogen. Weiterhin ist ein Rohrstück 12 vorgesehen, das einen größeren Durchmesser als das Rohrstück 6 besitzt und das konzentrisch zu der Achse des Rohrstückes 6 und der Wendelachse der Rohrheizkörper 11 angeordnet ist. Mit dem Rohrstück 12 ist eine Luftleitung 13 verbunden, so daß durch ein Gebläse 14 angesaugte Luft durch den von dem Rohr 6 und dem Rohr 12 gebildeten Ringkanal während des Trockungsvorganges getrieben wird.Three tubular heating elements 11 are arranged on the tubular piece 6, specifically the tubular heating elements 11 are bent helically around the tubular piece 6. Furthermore, a pipe section 12 is provided which has a larger diameter than the pipe section 6 and which is arranged concentrically to the axis of the pipe section 6 and the helical axis of the tubular heating element 11. An air line 13 is connected to the pipe section 12, so that air sucked in by a blower 14 is driven through the annular channel formed by the pipe 6 and the pipe 12 during the drying process.

Die Anordnung 7, 8, 9 ist drehbar in den oberen Enden der Rohrstücke 6 und 12 gelagert. Der untere Verteilerarm 7 ist mittels einer Scheidewand 15 zweigeteilt. Der untere Bereich des Verteilerarmes 7 steht mit dem Ringraum zwischen den Rohrstücken 6 und 12 in Verbindung, so daß die von dem Gebläse 14 angesaugte und über die Rohrheizkörper 11 streichende Luft aus Düsen 16 in den Innenraum des Behälters 1 ausgeblasen wird. Der obere Teil des Verteilerarms 7 sowie das Innere des Verteilerarmes 8 stehen mit dem Inneren des Rohrstückes 6 in Verbindung, so daß die von der Pumpe 5 umgetriebene Waschflüssigkeit über Sprühdüsen 17 auf das Geschirr ausgesprüht wird.The arrangement 7, 8, 9 is rotatably mounted in the upper ends of the pipe sections 6 and 12. The lower distributor arm 7 is divided in two by means of a partition 15. The lower region of the distributor arm 7 communicates with the annular space between the pipe sections 6 and 12, so that the air sucked in by the blower 14 and passing over the tubular heating element 11 is blown out of the nozzles 16 into the interior of the container 1. The upper part of the distributor arm 7 and the interior of the distributor arm 8 are connected to the interior of the pipe section 6, so that the washing liquid driven by the pump 5 is sprayed onto the dishes via spray nozzles 17.

Zur drehbaren Lagerung der in sich starren Anordnung aus dem Rohr 9 und den Verteilerarmen dienen Drehlager 18, welche an den oberen Enden der Rohre 6 und 12 angeordnet sind. Der Antrieb erfolgt in bekannter Weise durch den Rückstoß der aus den entsprechend schräggestellten Düsen 16 und 17 austretenden Medien ströme, d. h. des Spülmittelflüssigkeitsstromes bzw. des erhitzten Luftstromes.Rotary bearings 18, which are arranged at the upper ends of the tubes 6 and 12, serve for the rotatable mounting of the rigid arrangement of the tube 9 and the distributor arms. The drive takes place in a known manner by the recoil of the media emerging from the correspondingly inclined nozzles 16 and 17 streams, ie the detergent liquid flow or the heated air flow.

Die neuartige Ausbildung hat nun eine Reihe von Vorteilen:

  • Die Spülflüssigkeit kommt nicht mit dem Rohrheizkörper 11 in Berührung, so daß Ablagerungen auf denselben und örtliche Überhitzungen vermieden werden. Die Rohrmäntel der Rohrheizkörper 11 brauchen dementsprechend nicht aus teuren Chromnickelstählen zu bestehen, die außerdem noch besonders gegen Spannungsrißkorrosion geschützt werden müssen. Wenn bei bekannten Ausbildungen ein Rohrheizkörper einerSpannungsrißkorrosionunterliegt, dann besteht die Gefahr, daß die Spülflüssigkeit in den Rohrheizkörper eindringt und dementsprechend die Maschine unter Spannung gesetzt wird. Eine derartige Möglichkeit ist bei der neuartigen Ausbildung ausgeschlossen, so daß auch entsprechende Sicherheitsvorkehrungen entfallen können. Die Rohrheizkörper 11 sind weiterhin durch das Rohr 12 geschützt. Der Behälter 1 kann dementsprechend auch aus Kunststoff gefertigt werden, da keine Gefahr besteht, daß durch Strahlungshitze oder durch Absprühen von flüssigem Metall bei Überhitzung eines Rohrheizkörpers das Kunststoffgehäuse in Brand gerät. Weiterhin ist der Wärmeübergang sowohl auf den Spülflüssigkeitsstrom als auch auf den Luftstrom äußerst günstig, so daß eine entsprecheide Energieeinsparung erzielt wird. Da die Rohrheizkörper 11 in Form einer Wendel auf das Rohr 6 aufgebracht sind, wird der Luftstrom gedreht und entsprechend verwirbelt. Der Energiebedarf während des Trockenvorganges ist dementsprechend gering, so daß es genügt, wenn für den Trockenvorgang die Rohrheizkörper 11 in Serie geschaltet werden. Während des Aufheizvorganges der Spülflüssigkeit werden die Rohrheizkörper 11 parallel geschaltet, so daß sich eine möglichst kurze Aufheizzeit ergibt. Diese Parallelschaltung kann während des Spülvorganges beibehalten werden. Es kann jedoch dann auch einer der Rohrheizkörper 11 abgeschaltet oder in Serie dazugeschaltet werden.
The new training now has a number of advantages:
  • The flushing liquid does not come into contact with the tubular heating element 11, so that deposits on the same and local overheating are avoided. Accordingly, the pipe jackets of the tubular heating element 11 do not have to be made of expensive chromium-nickel steels, which also have to be particularly protected against stress corrosion cracking. If, in known designs, a tubular heating element is subject to stress corrosion cracking, there is a risk that the flushing liquid will penetrate into the tubular heating element and, accordingly, the machine will be energized. Such a possibility is excluded in the novel design, so that corresponding safety precautions can also be omitted. The tubular heater 11 are still protected by the tube 12. The container 1 can accordingly also be made of plastic, since there is no risk that the plastic housing will catch fire due to radiant heat or by spraying liquid metal when a tubular heating element overheats. Furthermore, the heat transfer to both the flushing liquid flow and the air flow is extremely favorable, so that a corresponding energy saving is achieved. Since the tubular heating elements 11 are applied to the tube 6 in the form of a spiral, the air flow is rotated and swirled accordingly. The energy requirement during the drying process is accordingly low, so that it is sufficient if the tubular heating elements 11 are connected in series for the drying process. During the heating process of the rinsing liquid, the tubular heating elements 11 are connected in parallel, so that the heating time is as short as possible. This parallel connection can be maintained during the rinsing process. However, one of the tubular heating elements 11 can then also be switched off or connected in series.

Besonders bewährt hat sich die koaxiale vertikale Anordnung des Rohres 6, der Rohrheizkörper 11 und des Rohres 12 im Unterteil der Geschirrspülmaschine, da auf diese Weise bei verhältnismäßig geringem Platzbedarf eine unbehinderte Führung der Medienströme und eine leichte Lagerung und Auswechselbarkeit der Anordnung aus den Verteilerarmen erzielt wird.The coaxial vertical arrangement of the tube 6, the tubular heater 11 and the tube 12 in the lower part of the dishwasher has proven particularly useful, since in this way an unimpeded guidance of the media streams and easy storage and interchangeability of the arrangement from the distributor arms is achieved with a relatively small space requirement .

Anstelle der Rohrheizkörper 11 können auch andere Heizeinrichtungen vorgesehen werden. So kann das Durchlaufrohr 6 auch von einem Druckgußteil gebildet werden, der an seiner Außenseite wendelförmige Rinnen zur Aufnahme von Heizwendeln und Isoliermaterial besitzt.Instead of the tubular heater 11, other heating devices can also be provided. Thus, the flow tube 6 can also be formed by a die-cast part that has helical grooves on its outside for receiving heating coils and insulating material.
