Abstract

Each cup (2) is positioned upside down in a cleansing chamber (4) between two outer rotary brushes (8) and over a single inner brush (9) mounted centrally on a pivot arm (10). The rotation is effected by a motor and belt drive to a central pulley (15) on the shaft of the inner brush. Pivotal motion of the arm is produced by another pulley (20) and a crank (21). A to-and-fro movement lifts the cup on to the inner brush for spraying from two vertical nozzles (40) and a lateral nozzle.

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.
Es sind 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.
Die bekannten Reinigungsvorrichtungen zeigen keine konkreten Lösungsvorschläge für dieses Problem.The invention relates to a cleaning device for reusable dishes, 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.
Tableware cleaning devices are 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.
The known cleaning devices show no concrete proposals for solving 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 dergleichne Geschirr möglich ist. Trotzdem soll dabei der Energie- und Reinigungsmittelbedarf möglichst gering sein.The object of the present invention is to provide a cleaning device of the type mentioned at the outset, with which a thorough cleaning of cups, mugs and similar dishes is possible in the shortest possible time. Nevertheless, the energy and cleaning agent requirements should be as low as possible.

Zur Lösung dieser Aufgabe wird erfindungsgemäß insbesondere vorgeschlagen, daß 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 daß die Vorrichtung einen Halte- und Hubmechanismus zum Zuführen und Überstülpen der Tasse auf die Innenbürste(n) aufweist.
Durch diese spezielle Anordnung der Reinigungsbürsten und deren Arbeitsbewegung erfolgt eine direkte mechanische Beaufschlagung der gesamten zu reinigenden Oberfläche des Geschirrteiles, 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 in particular that at least one outer brush engaging on the outside of the cup and pivotable in the circumferential direction of the cup and at least one rotating inner brush engaging on the inside of the cup are provided and that the device has a holding and lifting mechanism for feeding and putting on the cup on the inner brush (s).
This special arrangement of the cleaning brushes and their working movement results in a direct mechanical action on the entire surface of the dishes to be cleaned, so that intensive and thorough cleaning is possible in the shortest possible time in connection with a cleaning liquid, usually hot water with a little washing-up liquid. 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, vorzugsweise 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 eine 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. Auch innenseitig ergibt sich eine gründliche Reinigung der Tasse, da nach einer Weiterbildung der Erfindung eine zentral in die 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.
Die Maßnahme nach Anspruch 4 begünstigt einen einfachen und kompakten Aufbau der Reinigungsvorrichtung.
Nach einer Ausgestaltung der Erfindung ist vorgesehen, daß die Reinigungskammer beziehungsweise die Vorrichtung 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 verbunden ist. Dies ermöglicht eine einfache Handhabung, da die zu reinigende Tasse oder dergleichen aus der oberen Einsetzlage beim Schließen des Deckels automatisch nach unten in Reinigungsstellung positioniert wird.According to a preferred embodiment, it is provided that two, preferably 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 thorough cleaning and loading of the entire circumferential side of the cup, with the edges and the bottom region or bottom edge region being acted upon, since the brushes are positioned correspondingly close to the cup and the bristles at the top and protrude the lower rim of the cup radially inwards. A thorough cleaning of the cup also results on the inside, since according to a further development of the invention a rotating inner brush is provided which engages centrally in the cup, which preferably points downward with its opening and acts on the inside on the circumference. This brush is with hers undeformed outer contour 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.
The measure according to claim 4 favors a simple and compact structure of the cleaning device.
According to one embodiment of the invention, it is provided that the cleaning chamber or the device has an upper closure lid, which is connected to the holding and lifting mechanism for positioning the cup in a lowered cleaning position and in a raised insertion and removal position. This enables simple handling, since the cup or the like to be cleaned is automatically positioned downwards into the cleaning position when the lid is closed from the upper insert position.

Zusätzliche Ausgestaltungen der Erfindung sind in den weiteren Unteransprüchen aufgeführt. Nachstehend ist die Erfindung mit ihren wesentlichen Einzelheiten anhand der Zeichnungen noch näher erläutert.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 cups 2.
The cleaning device 1 essentially has a cleaning chamber 4 located in an outer housing 3, a drive device 5 and a hot water preparation 6.
Within the cleaning chamber 4 there is a holding and lifting mechanism 7 with which the cup 2 in the inserted position in FIG. 2 is positioned from this upper position into the cleaning position shown in FIG. 1 and from this again into the removal position corresponding to the inserted position (FIG. 2) can be.
In addition, in the cleaning chamber 4 there are external brushes 8 (see FIGS. 3 and 4) positioned to the side next to the cup 2 and an internal brush 9 which engages in the cup 2 pointing downwards. For the sake of clarity, the external brushes 8 are shown in the side views according to FIG 1 and 2 omitted.

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 outer brushes 8 are provided, which are pivotably and rotatably mounted at the ends of a pivotally mounted pivot arm 10. As can be clearly seen in FIG. 3, the outer brushes 8 point upwards with their bristle field and laterally act on the cup 2 located therebetween. The inner brush 9 is also rotatably mounted centrally on the swivel arm 10 and engages the cup 2 from below. The rotational movements of the outer brushes 8 and the inner brushes 9 and also the pivoting movement of the outer brushes 8 are derived from a common drive motor 11 via the drive device 5. 5 shows details of the drive device 5 recognizable. For the rotation of the outer brushes 8 and the inner brush 9, the rotary movement is transmitted from the motor shaft 12 via a pulley 13 and a belt 14 to a central pulley 15, which is located on the rotary shaft 16 of the inner brush 9. The rotational movement for the outer brushes 8 is transmitted from the pulley 15 via a belt 17 to two outer pulleys 18 which are attached to the rotating shafts 19 of the outer brushes 8.

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 outer brushes 8 also perform a counter-rotating swivel movement according to the double arrows Pf1 in FIGS. 4 and 5. For this purpose, a drive transmission from the motor shaft 12 takes place via a pulley 20 to a crank mechanism 21, in which the rotating rotary movement is converted into a reciprocating oscillating movement. This is transmitted to the swivel arm 10 via a belt 22.
As can be clearly seen in FIGS. 4 and 5, the outer brushes 8 are arranged approximately diametrically opposite one another and can each be pivoted in opposite directions to such an extent that practically the entire outside of the cup 2 is acted upon during a back and forth swiveling movement. In the exemplary embodiment, the connecting straight line between the two outer brushes 8 is provided offset somewhat parallel to the diameter of the cup or the cup support.

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 lifting mechanism 7 within the cleaning chamber 4 has a support 23 for the cup rim pointing downwards, this support having an annular body 24 with three support webs 25 (FIG. 4). The inner brush 9 engages through this ring body 24 and into the cup. The cup support 23 is connected to a lifting slide 27 mounted on a guide 26 (FIGS. 1 and 2), with which the cup 2 resting on the support 23 moves between the insertion and removal position (FIG. 2) and the cleaning position (FIG. 1) can be positioned here. The lifting slide 27 is via a Bowden cable 28 with a pivotable closure cover 29 connected. In the pivot bearing 30 of the closure cap 29, a pull lever 31 engages, the other end of which is connected to the Bowden cable 28.
On the inside, the closure lid 29 has a buffer-like hold-down device 32 for loading the bottom 33 of the cup 2 pointing downward.
If, after inserting a cup 2 to be cleaned (FIG. 2), the lid 29 is closed, the cup 2 is pushed down by the holding-down device 32 together with the lifting slide 27 into the cleaning position of the cup 2 with the lid 29 fully closed. After the cleaning process, the cover 29 can be swung open on its handle 34, the cup 2 being lifted upwards into the removal position by the drive transmission from the cover 29 via the pull lever 31 and the Bowden cable 28 to the lifting slide 27, and then correspondingly easily removable is. This mechanism enables a cup to be cleaned to be inserted and removed quickly and easily.
Instead of the Bowden cable 28, a permanent restoring force can be provided in the holding and lifting mechanism 7, preferably by a restoring spring. As a result, the cup is positioned in the raised insertion and removal position when the closure lid 29 is open. When the lid is closed, it acts on the bottom of the cup 2 pointing downward with its buffer-like hold-down device 32 and presses it against the restoring force in the lowered cleaning position.
In order to prevent the cup 2 from rotating when it is loaded by the brushes, its handle 35 engages in a slot running along the travel path between two guide rails 36.

Als Reinigungsflüssigkeit dient heißes Wasser, dem bedarfsweise ein Reinigungs- oder Spülmittel beigegeben werden kann.
