Abstract
Description
Die Erfindung bezieht sich auf eine Reinigungsvorrichtung für
Mehrwege-Geschirr, insbesondere für einzelne Tassen, mit einer
Reinigungskammer, in der sich Sprühdüsen für den Austritt von
Reinigungsmedium und Mittel zum Positionieren der Tasse innerhalb
der Reinigungskammer befinden, wobei wenigstens eine außen an der
Tasse angreifende und in Umfangsrichtung der Tasse verschwenkbare
Außenbürste sowie wenigstens eine innen an der Tasse angreifende,
rotierende Innenbürste vorgesehen sind und wobei die Vorrichtung
einen Halte- und Hubmechanismus zum Zuführen und Überstülpen der
Tasse auf die Innenbürste(n) aufweist.
Aus der US-A-3 866 265 ist eine Gläserwaschmaschine bekannt, bei
der die zu reinigenden Gläser einzeln von oben mit der Öffnung nach
unten in ein Gehäuse eingeführt werden, wobei das Glas mit seiner
umlaufenden Wand zwischen wenigstens einer inneren Bürste und
mehreren äußeren Bürsten eingreift.
Die Bürsten befinden sich in dem Gehäuse, das eine obere Einführöffnung
für zu reinigende Gläser aufweist. Während des Reinigungsvorgangs
bildet das Glas selbst einen oberen Abschluß der
Einführöffnung, wobei aber eine Abdichtung, insbesondere auch bei
unterschiedlichen Durchmessern von zu reinigenden Gläsern, nicht
möglich und dementsprechend der Austritt von Reinigungsflüssigkeit
nicht verhindert werden kann.
Auch ist es erforderlich, das zu reinigende Glas während der
Reinigungsprozedur direkt festzuhalten und nach unten zu bewegen,
so daß der Benutzer mit Spritzwasser und gegebenenfalls mit den
äußeren Bürsten in Berührung kommen kann.
Das Festhalten ist insbesondere auch bei schmalen Gläsern
erforderlich, da diese zwischen der inneren Bürste und in gleiche
Richtung rotierende, mittlere Bürsten eingreifen.
Zum Reinigen von im Durchmesser größeren Gläsern dienen die
mittleren, umlaufenden aber nicht rotierenden Bürsten zum Reinigen
der Glasinnenseite, während äußere, jeweils um ihre eigene Achse
rotierende, jedoch nicht umlaufende Bürsten zum Reinigen der
Glasaußenseite vorgesehen sind. Um die gesamte, äußere Umfangsseite
des Glases zu beaufschlagen, sind eine Vielzahl von Außen-Bürsten
erforderlich.The invention relates to a cleaning device for reusable crockery, in particular for individual cups, with a cleaning chamber in which there are spray nozzles for the discharge of cleaning medium and means for positioning the cup within the cleaning chamber, at least one acting on the outside of the cup and outer brush pivotable in the circumferential direction of the cup and at least one rotating inner brush acting on the inside of the cup are provided and the device has a holding and lifting mechanism for feeding and putting the cup on the inner brush (s).
From US-A-3 866 265 a glass washing machine is known in which the glasses to be cleaned are introduced individually from above with the opening downwards into a housing, the glass with its peripheral wall between at least one inner brush and several outer brushes intervenes.
The brushes are located in the housing, which has an upper insertion opening for glasses to be cleaned. During the cleaning process, the glass itself forms an upper end of the insertion opening, but sealing, in particular also in the case of different diameters of glasses to be cleaned, is not possible and, accordingly, the escape of cleaning liquid cannot be prevented.
It is also necessary to hold the glass to be cleaned directly during the cleaning procedure and to move it downward, so that the user can come into contact with splashing water and possibly with the outer brushes.
Holding on is particularly necessary with narrow glasses, since they engage between the inner brush and middle brushes rotating in the same direction.
The middle, rotating but not rotating brushes are used to clean the inside of the glass for cleaning larger-diameter glasses, while outer brushes rotating around their own axis but not rotating are used for cleaning the outside of the glass. A large number of external brushes are required to act on the entire outer peripheral side of the glass.
Es sind auch bereits Geschirr-Reinigungsvorrichtungen bekannt, bei
denen als Reinigungsmedium Sprühwasser, Dampf, Reinigungsbürsten
und zum Trocknen Luft verwendet werden. Bei solchen Reinigungsvorrichtungen
besteht das Problem, daß einerseits eine sehr kurze
Reinigungszeit erwünscht ist, daß andererseits aber trotz dieser
kurzen, zur Verfügung stehenden Zeit eine gründliche Reinigung der
Tasse gefordert ist, auch wenn Getränkereste an der Tasse oder
dergleichen eingetrocknet und schwer entfernbar sind.
Diese bekannten Reinigungsvorrichtungen zeigen jedoch keine konkreten
Lösungsvorschläge für dieses Problem.Tableware cleaning devices are also already known, in which spray water, steam, cleaning brushes and air for drying are used as the cleaning medium. The problem with such cleaning devices is that, on the one hand, a very short cleaning time is desired, but on the other hand, despite this short, available time, thorough cleaning of the cup is required, even if beverage residues on the cup or the like have dried out and are difficult to remove.
However, these known cleaning devices do not show any concrete solutions to this problem.
Aufgabe der vorliegenden Erfindung ist es, eine Reinigungsvorrichtung der eingangs erwähnten Art zu schaffen, mit der in kürzester Zeit eine gründliche Reinigung von Tassen, Bechern und dergleichen Geschirr möglich ist. Trotzdem soll dabei der Energie- und Reinigungsmittelbedarf möglichst gering sein. Außerdem soll ein einfacher Aufbau sowie eine einfache Handhabung und ein bequemes und schnelles Einsetzen und Entnehmen einer zu reinigenden Tasse möglich sein.The object of the present invention is a cleaning device of the type mentioned at the beginning, with the shortest time thorough cleaning of cups, mugs and the like Dishes are possible. Nevertheless, the energy and The need for cleaning agents should be as low as possible. In addition, a simple construction as well as easy handling and a convenient and quick insertion and removal of a cup to be cleaned to be possible.
Zur Lösung dieser Aufgabe wird erfindungsgemäß
vorgeschlagen, daß daß die Reinigungskammer einen oberen Verschlußdeckel
aufweist, der mit dem Halte- und Hubmechanismus zum
Positionieren der Tasse in eine abgesenkte Reinigungsstellung und
in eine angehobene Einsetz- und Entnahmestellung in Antriebsverbindung
steht, daß für die Schwenkbewegung der Außenbürste(n)
und die Rotationsbewegung der Innenbürste ein gemeinsamer Antrieb
vorgesehen ist, daß die Antriebsverbindung für die Schwenkbewegung
der Außenbürste(n) ein Kurbelgetriebe oder einen Exzenterantrieb
aufweist, daß die Außenbürste(n) an den Enden eines mit dem
Kurbelgetriebe oder dergleichen verbundenen Schwenkarmes
verschwenkbar sowie um ihre Längsachse drehbar gelagert sind und
daß der Antrieb für die Drehbewegung der Außenbürste(n) von dem
Antrieb für die Drehbewegung der Innenbürste abgeleitet ist (sind).
Durch die Antriebsverbindung zwischen dem Verschlußdeckel und dem
Halte- und Hubmechanismus ist eine einfache Handhabung ermöglicht,
da die zu reinigende Tasse aus der oberen Einsetzlage beim Schließen
des Deckels automatisch nach unten in Reinigungsstellung positioniert
wird.
Der gemeinsame Antrieb für die Schwenkbewegung und die Rotationsbewegung
der Außenbürste(n) sowie die Rotationsbewegung der
Innenbürste begünstigt einen einfachen und kompakten Aufbau der
Reinigungsvorrichtung, wobei sich durch die Verwendung eines
Kurbelgetriebes oder eines Exzenterantriebs Vorteile hinsichtlich
der Lebensdauer und der Betriebssicherheit ergeben.
Die vorgesehene Anordnung der Reinigungsbürsten und deren
Arbeitsbewegung mit Schwenkbewegung der Außenbürsten bei gleichzeitiger
Rotation ergibt ergibt eine direkte mechanische Beaufschlagung
der gesamten zu reinigenden Oberfläche der Tasse, so daß
in Verbindung mit einer Reinigungsflüssigkeit, in der Regel
Heißwasser mit etwas Spülmittel, in kürzester Zeit eine intensive
und gründliche Reinigung möglich ist. Versuche haben ergeben, daß
ein Reinigungszeit von nur 5 Sekunden für eine einwandfreie Reinigung
ausreichend ist. Durch diese sehr kurze Reinigungszeit ergibt sich
schon zwangsläufig ein geringer Verbrauch von Spülflüssigkeit und
Spülmittel und auch ein dementsprechend geringer Energiebedarf für
eine Aufheizung des Spülwassers.To achieve this object, it is proposed according to the invention that the cleaning chamber has an upper closure cover which is in drive connection with the holding and lifting mechanism for positioning the cup in a lowered cleaning position and in a raised insertion and removal position, that for the pivoting movement of the outer brush (n) and the rotational movement of the inner brush, a common drive is provided, that the drive connection for the pivoting movement of the outer brush (s) has a crank mechanism or an eccentric drive, that the outer brush (s) can be pivoted at the ends of a pivot arm connected to the crank mechanism or the like and are rotatably mounted about their longitudinal axis and that the drive for the rotary movement of the outer brush (s) is (are) derived from the drive for the rotary movement of the inner brush. The drive connection between the closure lid and the holding and lifting mechanism enables simple handling, since the cup to be cleaned is automatically positioned downwards in the cleaning position when the lid is closed when the lid is closed.
The common drive for the swiveling movement and the rotational movement of the outer brush (s) and the rotational movement of the inner brush favors a simple and compact structure of the cleaning device, whereby advantages in terms of service life and operational safety result from the use of a crank mechanism or an eccentric drive.
The proposed arrangement of the cleaning brushes and their working movement with swiveling movement of the outer brushes with simultaneous rotation results in a direct mechanical action on the entire surface of the cup to be cleaned, so that in conjunction with a cleaning liquid, usually hot water with a little washing-up liquid, an intensive one in the shortest possible time and thorough cleaning is possible. Experiments have shown that a cleaning time of only 5 seconds is sufficient for perfect cleaning. This very short cleaning time inevitably results in a lower consumption of washing-up liquid and washing-up liquid and also a correspondingly lower energy requirement for heating the washing-up water.
Nach einer bevorzugten Ausführungsform ist vorgesehen, daß zwei
etwa diametral zu der Tasse oder dergleichen gegenüberliegend
angeordnete, rotierende Außenbürsten vorgesehen sind, die
vorzugsweise gegenläufig um einen vorgebbaren Schwenkwinkel um die
Tasse schwenkbar sind. Durch die Schwenkbewegung der Außenbürsten
bei gleichzeitiger Rotation ergibt sich trotz Verwendung von nur
zwei Außenbürsten eine besonders gründliche Reinigung und eine
Beaufschlagung der gesamten Umfangsseite der Tasse, wobei die Ränder
und der Bodenbereich bzw. Bodenrandbereich mit beaufschlagt werden,
da die Bürsten entsprechend dicht an der Tasse positioniert sind
und die Borsten am oberen und unteren Tassenrand radial nach innen
überstehen. Durch die Verwendung von nur zwei Außenbürsten ist ein
entsprechend reduzierter Aufwand vorhanden.
Auch innenseitig ergibt sich eine gründliche Reinigung der Tasse,
da nach einer Weiterbildung der Erfindung eine zentral in die im
Betriebszustand mit ihrer Öffnung vorzugsweise nach unten weisende
Tasse eingreifende und diese innenseitig umfänglich beaufschlagende,
rotierende Innenbürste vorgesehen ist. Diese Bürste ist mit ihrer
unverformten Außenkontur etwas größer als der Tasseninnenraum, so
daß auch hier eine gründliche Reinigung in kürzester Zeit erfolgt,
selbst wenn angetrocknete Getränke- oder Speisereste abgelöst werden
müssen.
Zusätzliche Ausgestaltungen der Erfindung sind in den weiteren
Unteransprüchen aufgeführt. Nachstehend ist die Erfindung mit ihren
wesentlichen Einzelheiten anhand der Zeichnungen noch näher
erläutert.According to a preferred embodiment, it is provided that two rotating outer brushes arranged approximately diametrically opposite the cup or the like are provided, which are preferably pivotable in opposite directions about the cup by a predeterminable pivoting angle. The swiveling movement of the outer brushes with simultaneous rotation results in a particularly thorough cleaning and loading of the entire circumferential side of the cup despite the use of only two outer brushes, with the edges and the bottom region or bottom edge region being acted on, since the brushes are correspondingly close to the cup are positioned and the bristles protrude radially inwards at the top and bottom of the cup. By using only two outer brushes, there is a correspondingly reduced effort.
The inside of the cup is also thoroughly cleaned, since, according to a further development of the invention, a rotating inner brush is provided which engages centrally in the cup, which in the operating state preferably points downward, and acts on the inside circumferentially. With its undeformed outer contour, this brush is slightly larger than the inside of the cup, so that thorough cleaning can be carried out in the shortest possible time, even if dried-on beverage or food residues have to be removed.
Additional embodiments of the invention are listed in the further subclaims. The invention with its essential details is explained in more detail below with reference to the drawings.

In den Seitenansichten gemäß Figur 1 und 2 ist gut der innere
Aufbau der erfindnungsgemäßen Reinigungsvorrichtung 1 erkennbar.
Sie ist im Ausführungsbeispiel als sogenannter Eintassen-Spüler
ausgebildet und dient dementsprechend zum Reinigen von einzeln
zugeführten Tassen 2.
Die Reinigungsvorrichtung 1 weist im wesentlichen eine in einem
Außengehäuse 3 befindliche Reinigungskammer 4, eine Antriebseinrichtung
5 sowie eine Warmwasseraufbereitung 6 auf.
Innerhalb der Reinigungskammer 4 befindet sich eine Halte- und
Hubmechanismus 7, mit dem die in Figur 2 in Einsetzstellung
befindliche Tasse 2 von dieser Obenstellung in die in Figur 1
gezeigte Reinigungsstellung und von dieser auch wieder in die
der Einsetzstellung entsprechende Entnahmestellung (Figur 2)
positioniert werden kann.
Außerdem befinden sich in der Reinigungskammer 4 noch seitlich
außen neben der Tasse 2 positionierte Außenbürsten 8 (vgl. Figur
3 und 4) sowie eine in die nach unten weisende Tasse 2 eingreifende
Innenbürste 9. Der Übersichtlichkeit halber sind die
Außenbürsen 8 in den Seitenansichten nach Figur 1 und 2
weggelassen.The inner structure of the cleaning device 1 according to the invention can be clearly seen in the side views according to FIGS. 1 and 2. In the exemplary embodiment, it is designed as a so-called single-cup dishwasher and accordingly serves to clean individually supplied
The cleaning device 1 essentially has a

In addition, in the
Im Ausführungsbeispiel sind zwei Außenbürsten 8 vorgesehen, die
an den Enden eines mittig schwenkbar gelagerten Schwenkarmes 10
verschwenkbar und drehbar gelagert sind. Wie gut in Figur 3
erkennbar, weisen die Außenbürsten 8 mit ihrem Borstenfeld nach
oben und beaufschlagen seitlich die dazwischen befindliche Tasse
2. Die Innenbürste 9 ist zentral ebenfalls an dem Schwenkarm 10
drehbar gelagert und greift von unten in die Tasse 2 ein. Die
Rotationsbewegungen der Außenbürsten 8 sowie der Innenbürsten 9
und auch die Schwenkbewegung der Außenbürsten 8 werden über die
Antriebseinrichtung 5 von einem gemeinsamen Antriebsmotor 11
abgeleitet. In Figur 5 sind Einzelheiten der Antriebseinrichtung
5 erkennbar. Für die Rotation der Außenbürsten 8 und der
Innenbürste 9 erfolgt eine Übertragung der Drehbewegung von der
Motorwelle 12 über eine Riemenscheibe 13 und einen Riemen 14 zu
einer zentralen Riemenscheibe 15, die sich auf der Drehwelle 16
der Innenbürste 9 befindet. Die Rotationsbewegung für die
Außenbürsten 8 wird von der Riemenscheibe 15 über einen Riemen
17 auf zwei Außen-Riemenscheiben 18, die auf den Drehwellen 19
der Außenbürsten 8 angebracht sind, übertragen.In the exemplary embodiment, two
Zusätzlich zu der Rotationsbewegung führen die Außenbürsten 8
auch noch eine gegenläufige Schwenkbewegung gemäß den Doppelpfeilen
Pf1 in Figur 4 und 5 durch. Von der Motorwelle 12 erfolgt dazu
über eine Riemenscheibe 20 eine Antriebsübertragung zu einem
Kurbelgetriebe 21, in dem die umlaufende Drehbewegung in eine
Hin- und Her-Schwingbewegung umgesetzt wird. Diese wird über einen
Riemen 22 auf den Schwenkarm 10 übertragen.
Wie gut in den Figuren 4 und 5 erkennbar, sind die Außenbürsten
8 etwa diametral gegenüberliegend angeordnet und lassen sich
gegenläufig jeweils soweit verschwenken, daß praktisch die gesamte
Außenseite der Tasse 2 während einer Hin- und Herschwenkbewegung
beaufschlagt wird. Im Ausführungsbeispiel ist die Verbindungsgerade
zwischen den beiden Außenbürsten 8 etwas zum Durchmesser der Tasse
bzw. der Tassenauflage parallel versetzt vorgesehen.In addition to the rotational movement, the
As can be clearly seen in FIGS. 4 and 5, the
Der Halte- und Hubmechanismus 7 innerhalb der Reinigungskammer
4 weist eine Auflage 23 für den nach unten weisenden Tassenrand
auf, wobei diese Auflage einen Ringkörper 24 mit drei Auflagestegen
25 aufweist (Figur 4). Die Innenbürste 9 greift durch diesen
Ringkörper 24 hindurch und in die Tasse ein. Die Tassenauflage
23 ist mit einem an einer Führung 26 (Figur 1 und 2) gelagerten
Hubschlitten 27 verbunden, mit dem die auf der Auflage 23
aufliegende Tasse 2 zwischen der Einsetz- und Entnahmestellung
(Figur 2) und der Reinigungsstellung (Figur 1) hin und her
positioniert werden kann. Der Hubschlitten 27 ist über einen
Bowdenzug 28 mit einem verschwenkbaren Verschlußdeckel 29
verbunden. Bei der Schwenklagerung 30 des Verschlußdeckels 29
greift ein Zughebel 31 an, dessen anderes Ende mit dem Bowdenzug
28 verbunden ist.
Der Verschlußdeckel 29 weist innenseitig einen pufferartigen
Niederhalter 32 zur Baufschlagung des Bodens 33 der nach unten
weisenden Tasse 2 auf.
Wird nun nach dem Einsetzen einer zu reinigenden Tasse 2 (Figur
2) der Deckel 29 geschlossen, so wird die Tasse 2 durch den
Niederhalter 32 zusammen mit dem Hubschlitten 27 nach unten bis
in die Reinigungsposition der Tasse 2 bei vollständig geschlossenem
Deckel 29 verschoben. Nach Beendigung des Reinigungsvorganges kann
der Verschlußdeckel 29 an seinem Griff 34 aufgeschwenkt werden,
wobei durch die Antriebsübertragung von dem Verschlußdeckel 29
über den Zughebel 31 und den Bowdenzug 28 zu dem Hubschlitten
27, die Tasse 2 nach oben in Entnahmestellung angehoben wird und
dann entsprechend gut entnehmbar ist. Durch diesen Mechanismus
ist ein bequemes und schnelles Einsetzen und Entnehmem einer zu
reinigenden Tasse möglich.
Anstatt des Bowdenzuges 28 kann bei dem Halte- und Hubmechanismus
7 eine permanente Rückstellkraftbeaufschlagung, vorzugsweise durch
eine Rückstellfeder vorgesehen sein. Dadurch wird die Tasse bei
offenem Verschlußdeckel 29 in die angehobene Einsetz- und
Entnahmestellung positioniert. Beim Schließen des Deckels
beaufschlagt dieser mit seinem pufferartigen Niederhalter 32 den
Boden der nach unten weisenden Tasse 2 und drückt diese gegen
die Rückstellkraftbeaufschlagung in die abgesenkte Reinigungsstellung.
Um ein Mitdrehen der Tasse 2 bei Baufschlagung durch die Bürsten
zu vermeiden, greift sein Henkel 35 in einen längs des Hubweges
verlaufenden Schlitz zwischen zwei Führungsschienen 36 ein.The holding and
