Description

Sieb- und Filtereinrichtung für mit Flüssigkeit arbeitende Reinigungsmaschine Die Erfindung betrifft eine Sieb- und Filtereinrichtung für mit Flüssigkeit arbeitende Reinigungsmaschinen, insbesondere Geschirrspülmaschinen.Sieve and filter device for cleaning machines that work with liquids The invention relates to a sieve and filter device for those working with liquids Cleaning machines, in particular dishwashers.

Es sind Einrichtungen zum Abscheiden von festen Bestandteilen aus Flüssigkeiten bekannt, bei denen die auf einem rotationssymmetrisch gekrümmten Sieb sich ablagernden festen Bestandteile mit Bürsten entfernt werden. Die Bürsten sind dabei am Umfang eines rotierenden zylindrischen Körpers angebracht, der gleichachsig zur gekrümmten Siebfläche gelagert ist. Solche Einrichtungen haben den Nachteil, daß bei Abnutzung der Bürsten diese einzeln in radialer Richtung verstellt werden müssen und ihre Lagerung zu diesem Zweck entsprechend ausgebildet sein muß. Dies bedingt einen hohen Aufwand an technischen Mitteln an den Lagern der Bürsten.There are facilities for the separation of solid components Liquids known in which the on a rotationally symmetrically curved sieve solid components that have built up can be removed with brushes. The brushes are attached to the circumference of a rotating cylindrical body that is equiaxed is mounted to the curved screen surface. Such facilities have the disadvantage that when the brushes wear they are adjusted individually in the radial direction must and their storage must be designed accordingly for this purpose. this requires a lot of technical resources on the bearings of the brushes.

An einer Sieb- und Filtereinrichtung für mit Flüssigkeit arbeitende Reinigungsmaschinen, insbesondere Geschirrspülmaschinen, vereinfacht sich der technische Aufwand und die erforderliche Wartungsarbeit vornehmlich dadurch, daß erfindungsgemäß eine bekannte Siebreinigungseinrichtung angewendet ist, bei der ein rotationssymmetrischer Siebkörper von Bürsten überstrichen wird und die Siebreinigungseinrichtung in der Weise ausgebildet ist, daß der Siebkörper konisch ist und daß die Bürsten gegenüber dem Siebkörper axial verschiebbar sind. Bei dieser Anordnung nutzen sich die Bürsten gleichmäßig ab, da alle Bürsten gemeinsam verstellt werden. Die notwendigen Wertungsarbeiten beschränken sich somit auf einen Austausch des Bürstenträgers, mit dem die Bürsten zu einer Baueinheit zusammengefaßt sein können. Die Nachstellung der Bürsten erfolgt während des Betriebes der Maschine. Sie kann durch eine einzige Feder bewirkt werden, die auf den verschiebbaren Träger der Bürsten eine Kraft in axialer Richtung ausübt.On a sieve and filter device for those working with liquids Cleaning machines, in particular dishwashers, simplify the technical Effort and the necessary maintenance work mainly due to the fact that according to the invention a known sieve cleaning device is used in which a rotationally symmetrical The screen body is swept over by brushes and the screen cleaning device in the Way is designed that the screen body is conical and that the brushes opposite the screen body are axially displaceable. With this arrangement, the brushes make use of each other evenly, as all brushes are adjusted together. The necessary evaluation work are therefore limited to an exchange of the brush holder with which the brushes can be combined to form a unit. The brushes are adjusted while the machine is in operation. It can be done by a single spring, which exerts a force in the axial direction on the sliding support of the brushes.

Nach einer Weiterbildung der Erfindung ist der Siebkörper feststehend angeordnet; an einem gleichachsig zum Siebkörper angeordneten Träger sind die umlaufenden Bürsten befestigt.According to a further development of the invention, the screen body is stationary arranged; on a carrier arranged coaxially to the screen body are the circumferential Brushes attached.

Eine andere Weiterbildung der Erfindung ist dadurch gekennzeichnet, daß die Bürsten ortsfest angeordnet sind und der Siebkörper rotiert.Another development of the invention is characterized in that that the brushes are fixed and the screen body rotates.

Die Erfindung ist mit Vorteil auf alle Arten von Reinigungsmaschinen anwendbar, die mit Flüssigkeit arbeiten.The invention is advantageous in all types of cleaning machines applicable who work with liquid.

Ein Anwendungsbeispiel der Erfindung ist in der Abbildung dargestellt und im folgenden beschrieben. Es ist eine vereinfachte Darstellung einer Spülmaschine gezeigt, bei der die Reinigung durch Abspritzen des Spülgutes erfolgt. Die im Waschraum 1 über das Spülgut gespritzte Flüssigkeit 2 sowie die durch den Spülvorgang entstandenen Verunreinigungen sammeln sich im Sumpf 3 des Spülbeckens. Die Flüssigkeit wird durch den konischen Siebkörper 4 über die Saugleitung 5 von der Pumpe 6 abgesaugt und zu den Waschdüsen 12 gefördert. Die Außenfläche des konischen Siebkörpers 4 wird von den rotierenden Bürsten 7 überstrichen und gereinigt. Dabei sinken die vom Siebkörper abgestreiften festen Schmutzteile 10 zu Boden und werden beim Wechseln der Spülflüssigkeit durch Öffnen einer Entleerungsklappe 11 entfernt. Die Bürsten 7 sind mit ihrem Träger 13 gegen die Kraft einer Feder 14 axial verschiebbar auf einer angetriebenen Welle 8 angeordnet. Die beim Betrieb entstehende Abnutzung der Bürsten 7 wird durch eine axiale Verschiebung des Trägers 13 ausgeglichen. Ein Elektromotor 9 treibt die Bürsten 7 und die Pumpe 6 an.An example of the application of the invention is shown in the figure and described below. It is a simplified representation of a dishwasher shown, in which cleaning is carried out by hosing down the items to be washed. The one in the washroom 1 liquid 2 sprayed over the items to be washed, as well as those resulting from the washing process Impurities collect in the sump 3 of the sink. The liquid is through the conical screen body 4 is sucked off by the pump 6 via the suction line 5 and promoted to the washing nozzles 12. The outer surface of the conical screen body 4 is swept over by the rotating brushes 7 and cleaned. In the process, they sink from the strainer body stripped solid dirt particles 10 to the ground and are when changing the rinsing liquid removed by opening an emptying flap 11. The brushes 7 are with their carrier 13 against the force of a spring 14 axially displaceable on a driven shaft 8 arranged. The wear of the brushes 7 during operation is caused by a axial displacement of the carrier 13 compensated. An electric motor 9 drives the brushes 7 and the pump 6.
