Abstract
Description
Die Erfindung betrifft eine Vorrichtung mit einem Vorlagebehälter und einem Ausspülraum zur portionierten Zudosierung von insbesondere pulverförmigem Reinigermaterial aus dem Vorlagebehälter in den Ausspülraum zur Beschickung von gewerblichen Spül- oder Waschmaschinen.The invention relates to a device with a storage container and a rinsing space for portioned metering of, in particular, powdered cleaning material from the storage container into the rinsing space for loading commercial dishwashers or washing machines.
Eine solche Pulverdosiervorrichtung wird vorzugsweise in gewerblichen Geschirrspülmaschinen oder Waschmaschinen verwendet. In solchen Maschinen wird das Spül- oder Waschmittel in einem Vorlagebehälter permanent in so großer Menge bereitgehalten, daß das Reinigungsmittel jeweils bei Bedarf dem Frischwasser oder Umwälzwasser automatisch beizugeben ist. Beispielsweise wird ein in einen als Ausspülwanne ausgebildeten Ausspülraum einer gewerblichen Geschirrspülmaschine eindosiertes Pulverprodukt für die Vordosierung über ein Magnetventil mit kaltem oder warmem Frischwasser und für eine Nachdosierung mit warmem Umwälzwasser über ein Gefälle in den zu dosierenden Tank der zu versorgenden Maschine eingeschwemmt. In diesem Zusammenhang sind Dosiergeräte geschaffen worden, die es gestatten, pulverförmiges Reinigungsmittel gesteuert in den Ausspülraum einzubringen. Schwierigkeiten ergeben sich dann, wenn der Pulverreiniger durch Luftfeuchtigkeit verklumpt, klamm oder pastös geworden ist, so daß die Dosiermechanik nicht in der vorgesehenen Weise zur Wirkung kommen kann. Bei Pulverreinigern wird häufig eine größere Menge Reinigungsmittel in einen Vorlagebehälter geschüttet, so daß wegen des bei allmählichem Verbrauch abnehmenden Produktdrucks die Dosiereinheit im Laufe des Entleerens des Vorlagebehälters abnimmt.Such a powder metering device is preferably used in commercial dishwashers or washing machines. In such machines, the detergent or detergent is permanently kept in such a large quantity in a storage container that the detergent is to be added to the fresh water or circulating water automatically when required. For example, a powder product metered into a rinsing basin of a commercial dishwasher for pre-metering with a magnetic valve with cold or warm fresh water and for a metering with warm circulating water via a gradient is washed into the tank to be metered in the machine to be supplied. In this context, dosing devices have been created that allow powdered cleaning agents to be introduced into the rinsing space in a controlled manner. Difficulties arise when the powder cleaner has become clumped, clammy or pasty due to atmospheric moisture, so that the metering mechanism cannot work in the intended manner. In powder cleaners, a large amount of detergent is often poured into a storage container, so that because of the gradual Consumption decreasing product pressure the dosing unit decreases in the course of emptying the storage container.
Aufgabe der Erfindung ist die Schaffung einer Lösung, die sowohl die Zudosierung von einwandfrei rieselfähigem als auch von Pulverreiniger mit Schollen, Klumpen und dergleichen ermöglicht, wobei auch bei unterschiedlichem Höhenstand des Pulverreinigers im Vorlagebehälter stets im wesentlichen dieselbe Dosierleistung erreicht und zusätzlich die Gefahr des Eindringens von Feuchtigkeit aus dem Ausspülraum in den Vorlagebehälter vermindert wird.The object of the invention is to provide a solution that allows both the metering of perfectly free-flowing and powder cleaner with clods, lumps and the like, whereby even at different levels of the powder cleaner in the storage container always achieves essentially the same dosing and also the risk of penetration Moisture from the rinsing space is reduced in the storage container.
Bei einer Vorrichtung der eingangs genannten Art wird diese Aufgabe gemäß der Erfindung durch Dosierlöcher im Boden des Vorlagebehälters und je einen mit Abstand unter den Dosierlöchern angeordneten Auffangteller sowie eine im Raum zwischen der Unterseite des Bodens und den Auflagetellern bewegliche, die Tellerfläche im wesentlichen überstreichende Abstreifmechanik gelöst. Vorzugsweise sind die Dosierlöcher und die Auffangteller im wesentlichen symmetrisch um eine vertikale Achse verteilt.In a device of the type mentioned, this object is achieved according to the invention by metering holes in the bottom of the storage container and a collecting plate arranged at a distance below the metering holes and a movable in the space between the underside of the bottom and the support plates, the plate surface essentially sweeping scraper mechanism . The metering holes and the collecting plates are preferably distributed essentially symmetrically about a vertical axis.
Die Dosierlöcher im Boden des Vorlagebehälters sollen ein Hindurchrieseln von Reinigungspulver aus dem Vorlagebehälter auf den jeweils unter einem Dosierloch befindlichen Auffangteller ermöglichen. Hierbei rieselt jeweils soviel Pulverprodukt durch das einzelne Dosierloch, bis eine kegelstumpfförmige Einheit mit dem Schüttwinkel entsprechender Steigung am Rande des Dosierlochs anstößt. Weiteres Pulver kann durch das Loch erst nach unten strömen, wenn vorhandene portionierte Produktmengen zwischen der Unterseite des Bodens und in den Auffangtellern beiseite geschoben worden sind. Hierzu wird eine im Raum zwischen der Unterseite des Bodens und in den Auffangtellern bewegliche, die gesamte Tellerfläche im wesentlichen überstreichende Abstreifmechanik vorgesehen. Im Prinzip wird erfindungsgemäß also in Form von kegelstumpfförmigen Einheiten vordosiert und bei Bedarf mit Hilfe einer Abstreifmechanik das vordosierte Produkt der bestimmungsgemäßen Verwendung zugeführt. Ohne Betätigung der Abstreifmechanik dagegen bilden die vordosierten Produktmengen selbst einen Verschluß zwischen dem angrenzenden Teil des Maschineninnern und dem das weitere Pulverprodukt enthaltenden Vorlagebehälter, wodurch auch das Eindringen von Feuchtigkeit aus dem Ausspülraum in den Vorlagebehälter verhindert wird. Da die Pulverfüllung des Vorlagebehälters außer an den Dosierlöchern durch den Boden gestützt und gehalten wird, wirkt sich der Höhenstand des noch im Vorlagebehälter befindlichen Pulvers nicht nennenswert auf die Dosierleistung aus. Schließlich können die Dosierlöcher so groß gemacht werden und/oder es kann ein Rührer zum Verteilen des Reinigungspulvers am Boden vorgesehen werden, derart, daß auch schollen- oder klumpenförmig verbackener Pulverreiniger problemlos für die Dosiermechanik zugänglich ist.The dosing holes in the bottom of the storage container are intended to allow cleaning powder to trickle through from the storage container onto the collecting plate located under a dosing hole. In this case, as much powder product trickles through the individual metering hole until a truncated cone-shaped unit with a slope corresponding to the angle of repose hits the edge of the metering hole. Additional powder can only flow down through the hole when existing portioned product quantities have been pushed aside between the underside of the base and in the collecting plates. For this purpose, one which is movable in the space between the underside of the base and in the collecting plates and essentially sweeps over the entire plate surface Scraper mechanism provided. In principle, according to the invention, pre-metering is carried out in the form of frustoconical units and, if necessary, the pre-metered product is fed to the intended use with the aid of a scraper mechanism. Without actuation of the stripping mechanism, on the other hand, the pre-metered product quantities themselves form a seal between the adjacent part of the interior of the machine and the storage container containing the further powder product, which also prevents the penetration of moisture from the rinsing space into the storage container. Since the powder filling of the storage container is supported and held by the floor in addition to the dosing holes, the level of the powder still in the storage container has no significant effect on the dosing performance. Finally, the metering holes can be made so large and / or a stirrer can be provided for distributing the cleaning powder on the floor, in such a way that powder cleaner which is clumped or clumped is easily accessible for the metering mechanism.
Gemäß weiterer Erfindung besteht die Abstreifmechanik der Auffangteller, aus mindestens einem um die vertikale Achse, um welche Dosierlöcher und Auffangteller im wesentlichen symmetrisch verteilt sein sollen, drehbar gelagerten Dosierfinger. Bei Verwendung von drei Dosierlöchern und drei Auffangtellern kann es für eine gleichmäßige Dosierung günstig sein, eine Abstreifmechanik bestehend aus vier zu der Achse symmetrischen Dosierfingern vorzusehen. Eine einfach herzustellende Form der Auffangteller besteht aus an der vertikalen Achse befestigten, in Umfangsrichtung auf Abstand gesetzten Kreissektoren jeweils senkrecht unterhalb eines Dosierloches. Der Durchlaßquerschnitt der Dosierlöcher, der vertikale Abstand zwischen Unterseite des Bodens und den Auffangtellern sowie die Fläche der letzteren im Bereich unterhalb der Dosierlöcher sollen dann dem Schüttwinkel des Reinigungspulvers entsprechend so aufeinander abgestimmt werden, daß bei stillstehender Abstreifmechanik der Durchgang zwischen Vorlagebehälter und Ausspülraum durch vordosiertes Reinigungspulver gesperrt wird. Es wird auf diese Weise also eine selbstsperrende Dosiermechanik geschaffen.According to a further invention, the scraper mechanism of the collecting plate consists of at least one metering finger rotatably mounted about the vertical axis, about which metering holes and collecting plate are to be distributed essentially symmetrically. When using three dosing holes and three collecting plates, it may be advantageous for a uniform dosing to provide a wiper mechanism consisting of four dosing fingers symmetrical to the axis. A simple form of the collecting plate consists of circular sectors attached to the vertical axis and spaced apart in the circumferential direction, each vertically below a metering hole. The passage cross section of the metering holes, the vertical distance between the underside of the bottom and the collecting plates and the area of the latter in the area below the metering holes should then be the angle of repose of the cleaning powder must be coordinated accordingly so that the passage between the storage container and the rinsing space is blocked by pre-metered cleaning powder when the scraper mechanism is at a standstill. In this way, a self-locking metering mechanism is created.
Gemäß noch weiterer Erfindung wird im Boden des Vorlagebehälters eine, vorzugsweise in Bezug auf die vertikale Achse symmetrische Mulde vorgesehen, in deren Bodenfläche sich die Dosierlöcher befinden sollen. Unmittelbar oberhalb der Dosierlöcher, innerhalb der Mulde und ggf. zusätzlich oder stattdessen unmittelbar an dem die Mulde umgebenden Boden des Vorlagebehälters können Rührer mit einem oder mehreren Rührfingern drehbar um die vertikale Achse vorgesehen werden. Mit Hilfe dieser Rührer kann auch mehr oder weniger stark verbackenes Pulverprodukt problemlos und ständig in die Dosierlöcher eingebracht werden, wenn die unterhalb des Bodens angeordnete Abstreifmechanik in Betrieb ist.According to yet another invention, a trough, preferably symmetrical with respect to the vertical axis, is provided in the bottom of the storage container, in the bottom surface of which the metering holes are to be located. Stirrers with one or more stirring fingers can be provided rotatably about the vertical axis directly above the metering holes, inside the trough and possibly additionally or instead directly on the bottom of the storage container surrounding the trough. With the help of these stirrers, more or less heavily baked powder product can be easily and continuously introduced into the metering holes when the scraper mechanism located below the bottom is in operation.
Durch die auf die Auffangteller portionierten Pulvermengen und die ebenfalls erfindungsgemäße dynamische Zwangsabräumung der Auffangteller mit Hilfe der Abstreifmechanik wird eine zuverlässige Pulverdosierung gewährleistet. Falls die Gefahr besteht, daß sich an den Abstreifflächen der Abstreifmechanik feuchtes Pulverprodukt ansetzt, werden diese Dosiermittel regelmäßig, beispielsweise bei jeder Umdrehung einmal, an einer Bügelfeder oder dergleichen abgestreift.Reliable powder metering is ensured by the powder quantities portioned onto the collecting plates and the dynamic forced clearing of the collecting plates according to the invention with the help of the stripping mechanism. If there is a risk that moist powder product will accumulate on the stripping surfaces of the stripping mechanism, these dosing means are stripped regularly, for example once every revolution, on a bow spring or the like.
Die Absteifmechanik wird so ausgebildet, daß sie auch nach längerer Stillstandzeit verkrustete und verhärtete Pulverkegel auf den Auffangtellern nach Einschalten mühelos in den nachgeschalteten Ausspülraum abräumen kann.The stiffening mechanism is designed in such a way that it can effortlessly clear incrusted and hardened powder cones on the collecting plates after switching on after switching on in the downstream rinsing area.
Als Antrieb der Dosier- und Rührmechanik der erfindungsgemäßen Pulverdosierungsvorrichtung wird vorzugsweise ein Elektromotor, insbesondere Spaltpolmotor mit Getriebeuntersetzung, vorgesehen, dessen Abtriebswelle in der vertikalen Achse von Dosierlöchern und Auffangstellern liegen soll. Der Antrieb soll dabei als geschlossener Block unterhalb des Ausspülraums angeordnet werden, damit der Raum oberhalb der Dosiervorrichtung zum Aufsetzen eines im Handel erhältichen Pulvergebindes frei bleibt.An electric motor, in particular a shaded-pole motor with gear reduction, is preferably provided as the drive for the metering and stirring mechanism of the powder metering device according to the invention, the output shaft of which should lie in the vertical axis of metering holes and catch points. The drive is to be arranged as a closed block below the rinsing space, so that the space above the metering device remains free for placing a commercially available powder container.
Der Boden des Vorlagebehälters und die beweglichen Teile von Abstreifmechanik und Rührer einschließlich der zugehörigen Achse sollen wegen der Aggressivität des eingesetzten Reinigers und der erforderlichen Stabilität der bewegten Teile vorzugsweise aus Edelstahl, V 4, bestehen. Die Auffangteller und der Boden des Ausspülraums können dagegen im wesentlichen aus ebenfalls gegenüber dem aggressiven Reinigungspulver beständigen Kunststoff, z. B. PE oder PP, bestehen.The bottom of the storage container and the moving parts of the scraper mechanism and stirrer including the associated axis should preferably be made of stainless steel, V 4, because of the aggressiveness of the cleaner used and the required stability of the moving parts. The collecting plate and the bottom of the rinsing space can, however, essentially consist of plastic, which is also resistant to the aggressive cleaning powder, e.g. B. PE or PP exist.
Um eine Beobachtung des Pulvervorrates in dem Vorlagebehälter zu ermöglichen, sieht die Erfindung weiterhin vor, daß der Vorlagebehälter aus transparentem Kunststoff besteht.In order to enable observation of the powder supply in the storage container, the invention further provides that the storage container consists of transparent plastic.
Um die Gefahr des Eindringens von Feuchtigkeit in den Vorlagebehälter noch weiter zu vermindern, sieht die Erfindung weiterhin einen an dem Ausspülraum über dem Wasserabfluß angeordneten kaminartigen Wrasenabzug vor. Dieser ist insbesondere bei einer Vorrichtung mit permanent von Umwälzwasser durchflossenem Ausspülraum zweckmäßig.In order to further reduce the risk of moisture penetrating into the storage container, the invention further provides a chimney-like fume hood arranged on the rinsing space above the water outlet. This is particularly expedient in the case of a device with a rinsing space through which circulating water flows permanently.
Verstärkt unterstützt wird die Wirkung des Wrasenabzuges durch ein im Übergang vom Ausspülraum zum Wrasenabzug angeordnetes Luftleitblech mit aerodynamisch ausgebildeter Umströmungskante und in den Seitenwänden des Ausspülraumes ausgebildete Luftschlitze, wie die Erfindung es ebenfalls vorsieht. Durch das Luftleitblech und die Luftschlitze wird in Zusammenwirken mit dem Wrasenabzug in dem Ausspülraum eine Luftströmung erzeugt, die etwa entstehende Feuchtigkeitsnebel in den Wrasenabzug zieht, so daß die Feuchtigkeit von der Dosiermechanik ferngehalten wird. Das Luftleitblech ist dabei derart ausgebildet, daß sich etwa daran niederschlagende Feuchtigkeit im Bereich der Umströmungskante sammelt und dann von dem Luftstrom in den Wrasenabzug mitgerissen wird. Die Luftschlitze sind in einer Höhe angeordnet, die deutlich über dem normalen Flüssigkeitsspiegel in dem Ausspülraum liegt.The effect of the vapor extraction is enhanced by an air baffle arranged in the transition from the rinsing space to the vapor extraction, with an aerodynamically designed flow-around edge and in the side walls of the rinsing space Louvres, as the invention also provides. Through the air baffle and the air slots, an air flow is generated in cooperation with the fume hood in the rinsing space, which draws any moisture mist into the fume hood, so that the moisture is kept away from the metering mechanism. The air baffle is designed in such a way that moisture, which is deposited thereon, collects in the region of the flow-around edge and is then entrained by the air flow into the vapor exhaust. The louvers are arranged at a height that is significantly above the normal liquid level in the rinsing space.
Zur Vermeidung von Spritzwasserbildung und zur Erzielung eines geregelten Strömungsverlaufes der Flüssigkeit in dem Ausspülraum zeichnet sich die erfindungsgemäße Vorrichtung weiterhin dadurch aus, daß im Ausspülraum ein die Antriebswelle für den Rührer umfassender, querschnittlich im wesentlichen rautenförmiger Leitkern angeordnet ist.To avoid the formation of splash water and to achieve a regulated flow of the liquid in the rinsing space, the device according to the invention is further characterized in that in the rinsing space a drive shaft for the stirrer comprising a cross-sectionally essentially diamond-shaped guide core is arranged.
Besonders schonend, sowie unter Zurückhaltung etwa mitgeführter Speisereste wird das Umwälzwasser gemäß weiterer Erfindung durch eine als Wasserverteillippe ausgebildete Umwälzwasser-Zuführeinrichtung im Ausspülraum zugeführt.Particularly gently, and with restraint of any food residues that are carried along, the circulating water according to a further invention is supplied in the rinsing space by a circulating water supply device designed as a water distribution lip.
Schließlich sieht die Erfindung in weiterer Ausbildung zumindest eine im Bereich des Wasserablaufes angeordnete Elektrode zur Erfassung der Wasserstandshöhe im Ausspülraum vor.Finally, the invention provides in a further embodiment at least one electrode arranged in the area of the water drain for detecting the water level in the rinsing space.

Der Vorlagebehälter 2 wird so groß bzw. passend ausgebildet, daß er für die Aufnahme eines Originalgebindes geeignet ist. Er weist einen Deckel 4 auf und ist damit an seiner Oberseite gegen Feuchtigkeitszutritt verschließbar. Am Boden des Vorlagebehälters können (nicht gezeichnet) Mittel zum Öffnen beispielsweise Aufstechen, einer ungeöffnet in den Behälter eingebrachten Originalpackung vorgesehen werden.The device shown in FIGS. 1 to 4 and generally designated 1 consists of a
Im Ausführungsbeispiel enthält der vorzugsweise aus V 4 A -Edelstahl bestehende und in Richtung auf die Mittelachse 6 des Behälters 2 geneigte Boden 5 mittig eine Mulde 7, in deren Boden 8 Dosierlöcher 9 vorgesehen sind. Unterhalb jedes Dosierlochs befindet sich ebenfalls ortsfest ein sektorförmiger Auffangteller 10. Zweckmäßig werden je drei Dosierlöcher 9 und Auffangteller 10 auf einem Teilkreis nahezu symmetrisch in bezug auf die Mittelachse 6 angeordnet.In the exemplary embodiment, the
Zwischen dem Boden 8 der Mulde 7 und den Auffangtellern 10 wird drehbar um die Mittelachse 6 eine Abstreifmechanik 11 bestehend beispielsweise aus vier Dosierfingern 12 vorgesehen. Oberhalb des Bodens 8 der Mulde 7 wird im Ausführungsbeispiel ein Rührer 13 bestehend aus zwei Gruppen 14 und 15 von Rührfingern drehbar um die Mittelachse 6 angeordnet. Die Rührfinger 14 werden dabei innerhalb der Mulde 7 bewegt, während die Rührfinger 15 auch den die Mulde 7 umgebenden Boden 5 des Vorlagebehälters 2 überstreichen. Durch den Rührer 13 wird erreicht, daß auch angefeuchtetes oder verklumptes oder in Schollen vorliegendes Pulverprodukt zuverlässig in die Dosierlöcher 9 einzubringen und zu dosieren ist.Between the
Bei Betrieb fällt durch die Dosierlöcher 9 Pulverprodukt auf die Auffangteller 10 und bleibt dort als kegelstumpfförmige Dosiereinheit 16 liegen. Bei Bedarf an Reinigungsmittel in der nachgeschalteten Maschine wird die Abstreifmechanik 11 eingeschaltet, derart, daß die Dosierfinger die kegelstumpfförmig auf den Auffangtellern 10 liegenden Dosiereinheiten 18 über die jeweilige radial verlaufende Kante 17 der Auffangteller 10 in einem darunter fest angeordneten, als Ausspülwanne ausgebildeten Ausspülraum 3 abstreifen. Gleichzeitig werden mit den rotierenden Rührfingern 14, 15 über die Mulde 7 bei zur Mitte geneigter Bodenfläche 5 des Vorlagebehälters 2 die Dosierlöcher 9 permanent mit Pulverprodukt 18 versorgt. Um eine übermäßige Pulverbeschichtung der Abstreifflächen der Dosierfinger 12 zu verhindern, werden die Dosierfinger 12 bei jeder Umdrehung einmal von einer Bügelfeder 19 abgestreift.During operation, powder product falls through the
Das in den Ausspülraum 3 dosierte Pulverprodukt wird mit Hilfe einer Wasserverteilerlippe 20, die duch die Leitung 24 mit ca. 60 °C warmem Umwälzwasser versorgt wird, über ein Gefälle und anschließend durch den Wasserablauf 21, dem eine hier nicht näher dargestellt Kreiselpumpe oder einen Injektor nachgeschaltet ist, beispielsweise zu einer Geschirrspülmaschine gefördert. Gewünschtenfalls kann dem Ausspülraum 3 über eine Düse 25 auch kaltes oder warmes Frischwasser zugeführt werden. Ist die Vorrichtung 1 einer Waschmaschine zugeordnet, wird dem Ausspülraum 3 nur kaltes Frischwasser zugeführt.The powder product dosed into the rinsing
Zum Antrieb des Rührers 13 und der Abstreifmechanik 11 wird, aus Platzgründen zweckmäßig unterhalb des Ausspülraums 3 ein Elektromotor 22 mit Untersetzungsgetriebe 23 vorgesehen. Der Antrieb über in der Mittelachse 6 liegende Wellen kann so ausgebildet und steuerbar sein, daß entweder der Rührer 13 und die Abstreifmechanik 11 gemeinsam rotieren, oder daß der Rührer 13 permanent und die Abstreifmechanik 11 jeweils wenn Reinigungsmittel benötigt wird, zu rotieren sind.To drive the
Wenn im Boden 8 der Mulde 7 drei Dosierlöcher 9 vorgesehen werden sollen, kommen z. B. folgende Maße in Frage:
Durchmesser der Dosierlöcher = 18mm
Radius des Lochkreises = 31mm
Sektorgröße der Auffangteller = 80 °
Abstand Auffangteller/Boden = 10mmIf in the
Diameter of the dosing holes = 18mm
Radius of the bolt circle = 31mm
Sector size of the collecting plate = 80 °
Distance collecting tray / floor = 10mm
Die Wasserverteillippe 20 ist so ausgebildet, daß sie das zufließende Umwälzwasser gleichmäßig über die Bodenfläche des Ausspülraumes 3 verteilt. Etwaige in dem Umwälzwasser mitgeführte Speisereste können sich aber aus der an einer Achse 26 beweglich gelagerten Wasserverteillippe 20 lösen und fließen durch den Wasserablauf 21 wieder der Geschirrspülmaschine zu.The
Zur Ableitung von bei der Einspülung des ca. 60 °C warmen Umwälzwassers entstehenden wasserdampfförmigen Wrasen ist an der Vorrichtung 1 über dem Wasserablauf 21 ein kaminartiger Wrasenabzugsschacht 27 angeordnet. In den Seitenwänden des Ausspülraumes 3 befinden sich Luftschlitze 28, von denen einer in Figur 1 gestrichelt dargestellt ist. Zusammen mit durch die Luftschlitze 28 zuströmender Frischluft werden die sich in dem Ausspülraum 3 bildenden Wrasen von dem Wrasenabzugsschacht 27 aufgenommen und in die Umgebung abgeführt. Um Verwirbelungen von Wrasen und Luft durch Kanten und Flächen an der Dosiermechanik im Bereich des Ausspülraumes zu verhindern, sind diese in Strömungsrichtung aerodynamisch ausgelegt. Insbesondere ist im Übergangsbereich vom Ausspülraum 3 zum Wrasenabzugsschacht 27 ein Luftleitblech 29 mit einer aerodynamisch ausgebildeten Umströmungskante 30 angeordnet. Duch den Wrasenabzugsschacht 27, die Luftschlitze 28 und das Luftleitblech 29 wird eine Luftströmung erzeugt, die verhindert, daß sich Feuchtigkeit im Bereich der Dosiermechanik niederschlagen kann.A chimney-like
Im Bereich der Leitung 24 ist unterhalb des Ausspülraums 3 eine Kohlenstoff-Durchflußelektrode 31 zur Leitfähigkeitsmessung des zulaufenden Umwälzwassers installiert. Bei Unterschreiten eines festgelegten Leitfähigkeitswertes wird die Abstreifmechanik 11 in Gang gesetzt und Reinigungspulver in den Ausspülraum dosiert. Es kann aber auch vorgesehen sein, der Abstreifmechanik 11 ein Zeitrelais zuzuordnen, mit deren Hilfe die Abstreifmechanik 11 automatisch in bestimmten Zeitabständen betätigt wird, da sich die erfindungsgemäße Vorrichtung außergewöhnlich gut für eine exakte Zeit/Mengenregelung eignet.In the area of the
Schließlich sind innerhalb des Ausspülraums 3 im Bereich des Wasserablaufes 21 zwei Elektroden 32 zur Erfassung der Wasserstandshöhe im Ausspülraum vorgesehen. Die höher angeordnete Elektrode schaltet bei einem zu hohen Flüssigkeitsspiegel die Wasserzufuhr ab, und die niedriger angeordnete Elektrode schaltet bei zu geringem Flüssigkeitsspiegel in dem Ausspülraum 3 den Elektromotor 22 aus.Finally, two
Ferner ist in dem Ausspülraum 3 um die Antriebswelle für den Rührer 13 herum ein querschnittlich im wesentlichen rautenförmiger Leitkern 33 angeordnet, der von dem zulaufenden Wasser in Richtung des Pfeiles gemäß Figur 4 umströmt wird.Furthermore, in the rinsing
Schließlich ist dem Deckel 4 noch ein Sicherheitsschalter 34 zugeordnet, der bei nicht geschlossenem Deckel ein Einschalten der Dosiermechanik bzw. die Zuführung von Wasser unterbindet.Finally, the cover 4 is also assigned a
