Description
Vorrichtung im Spülwasser-Kreislaufsystem von Geschirrwaschmaschinen zum Reinigen des umlaufenden Spülwassers. Gegenstand der Erfindung ist eine Vor richtung im Spülwasser-Kreislaufsystem von Geschirrwaschmaschinen zum Reinigen des umlaufenden Spülwassers. Die Spül wasser führenden Organe der Vorrichtung sind so angeordnet, dass ein vom Spülwasser durchströmtes Sieb sowohl während des Be triebes der Vorrichtung, wie auch beim Ab lassen des Spülwassers selbsttätig durch ;die Strömung des Spülwassers gereinigt -,wird.
Die Zeichnung zeigt in Fig. 1. die Ge samtanordnung eines Ausführungsbeispiels der Vorrichtung im Vertikalschnitt, in den Fig. 2, bis 4 in vergrössertem Massstabe einige weitere Ausführungsbeispiele der Siebanord nung, ebenfalls im Vertikalschnitt, alles in schematischer Darstellung.
Unter der wegnehmbaren Glocke 1 in Fig. 1 wird das nicht gezeichnete zu rei nigende Geschirr auf einem ebenfalls nicht gezeichneten Gestell aufgeschichtet. Mittelst der Spritzvorrichtung 2 werden Wasser strahlen gegen .das Geschirr gespritzt. Das abfliessende Spülwasser sammelt sich im Trichter 3 und fliesst durch einen Rohr stutzen 4 nach dem Wasserbehälter 5. Von hier aus fliesst es durch ein Rohr 6, in wel ches eine Schraubenfläche 7 eingebaut ist, in den Einlaufhohlraum 8 und den Innenraum des zylindrischen iSiebers 9.
Durch die Schraubenfläche 7 erhält das Spülwasser zu der abwärts gerichteten mit verhältnis mässig geringer Geschwindigkeit erfolgenden Hauptströmung eine zusätzliche rasche Ro tationsbewegung, so dass aus beiden Bewe gungen die durch einen gewundenen Pfeil angedeutete Schraubenströmung im Sieb innenraum 8 resultiert. Durch die Öffnun gen .des Siebes 9' hindurch strömt das Spül wasser in den zylinderringförmigen Ablauf- hohlraum 10, welcher durch das Sieb 9 und den zylindrischen Mantel 11 gebildet wird. Ein Deckel 12 mit einem Ablasskanal 13 schliesst den Ringraum 10 nach unten ab und hält gleichzeitig das Sieb 9 in seiner Lage.
Der obere erweiterte Teil 14 des Ablass- kanales 13 .dient gleichzeitig als Sammel raum für die Rückstände, welche durch die Schraubenströmung im Einlaufhohlraum 8 von der Innenfläche der Siebes 9 weggespült und nach unten befördert werden. Der Ab lasskanal 13 trägt einen Ablasshahn 15, wel cher in der gezeichneten Stellung geschlos sen ist.
Aus dem Ringraum 10 fliesst das Spül wasser durch .das Rohr 16 einer beliebig an getriebenen Pumpe 17 von beliebiger Bauart zu. Diese fördert das Spülwasser durch ein Rohr 18 wieder zur Spritzvorrichtung 2, und der Kreislauf des Spülwassers beginnt hier von neuem.
Nach beendigter Geschirr-Reinigung wird die Pumpe 17 zum Stillstand gebracht und durch Öffnen das Hahnes 15 das Spülwasser abgelassen. Nun strömt einerseits aus dem Wasserbehälter 5 das Spülwasser wie bisher schraubengangartig durch den Siebinnenraum 8 nach unten, indem es dabei etwa noch an der Innenfläche des Siebes 9 haftende Rück stände mitnimmt.
Gleichzeitig strömt aber aus der Spritzvorrichtung 2, aus Rohr 18, Pumpe 17 und Rohr 16 das darin befindliche Spülwasser zurück in den Ringraum 10 und von da durch die Öffnungen des Siebes 9 in den .Siebinnenraum 8 und hilft seiner seits durch diese rückläufige Strömung die noch an der Siebinnenfläche haftenden Rück stände zu entfernen. Die Pumpe 17 muss natürlich von geeigneter Bauart sein, da mit sie bei Stillstand diese Rückströmung gestattet.
Ehe das Spülwasser durch den Hahn 15 abfliessen kann, drückt es zuerst die im Raum 14 angesammelten Rückstände vor sich her durch den Hahn hinaus. , Durch Anbringung einer Durchgangsöff nung 15a von geeigneter Grösse im Hahn 15 hat man es in der Hand, den Abfluss des Spülwassers mit einer für eine gründliche Reinigung des Siebes und der ganzen Vor richtung möglichst günstigen Geschwindig keit abfliessen zu lassen.
Die in den Fig. 2 und 3 dargestellten Siebanordnungen sind Ausführungsbeispiele von einfacherer Bauart als die Anordnung nach Fig. 1.
In Fig. 3 ist das Sieb 9 *in einer gegen die Horizontale wenig geneigten Lage ange ordnet. Der Einlaufhohlraum 8 liegt unter, der Auslaufhohlraum 10 über dem Sieb 9. Durch Rohr 6 gelangt das Spülwasser in dea Raum 8, den es vorwiegend \horizontal durch strömt. Die Strömung hat eine grosse Be wegungskomponente entlang der Fläche des Siebes 9, welche die vom Sieb zurückgehal tenen Rückstände nach dem Sammelraum 11 befördert. Nach dem Durchtritt durch das Sieb 91 gelangt das Spülwasser in den Aus laufraum 10 und strömt von da durch Rohr 16 zur Pumpe. Durch den Hahn 15: können Rückstände und Spülwasser abgelassen wer den.
Die Anordnung nach Fig. 2 unterschei det sich von der vorbeschriebenen im wesent lichen nur durch die senkrechte Anordnung des Siebes.
Die Anordnung nach Fig. 3 hat den Vor teil sehr geringer Bauhöhe; bei der Anord nung nach Fig. 2 begünstigt die natürliche Sinkbewegung der Rückstände, indem sie mit der Strömungsrichtung zusammenfällt, deren Abscheidung.
Das Ausführungsbeispiel der Siebanord nung nach Fig. 4 verbindet verhältnismässig geringe Bauhöhe mit der Anwendung der sehr vorteilhaften Schraubenströmung. Gleich zeitig ist es ein Beispiel \für die Verwendung des das Sieb umgebenden Ringhohlraumes als<B>Ei</B> inlaufhohlraum.
Durch das Rohr 6 strömt das .Spülwasser tangential in den zwischen dem Sieb 9 und dem Mantel 11 gelegenen Ringhohlraum 8 ein, wodurch eine Rotationsströmung um das Sieb 9 herum entsteht. Durch das gleich zeitige verhältnismässig langsame Fort schreiten der Flüssigkeit in Achsenrichtung des Zylinderringraumes entsteht die ge wünschte Schraubenströmung, die noch durch schraubenförmige Rippen 7a im Raum 8 un terstützt werden kann. Die Rückstände wer den dabei nach dem Sammelraum 14 gespült. Die leicht geneigte Lage des Zylinders 11 begünstigt die Bewegung der Rückstände.
Die Rippen 7a können zwecks besseren Ab wärtsspülens der Rückstände unterhalb des Siebes 9 bei 7h oder auch an andern Stellen des Umfangs unterbrochen sein. Während des achsialen Fortschreitens des Spülwassers im Raum 8 tritt dasselbe allmählich nach dem Siebinnenraum 10 über und fliesst von da durch Rohr 16 zur Pumpe.
Device in the rinse water circulation system of dishwashers for cleaning the circulating rinse water. The invention relates to a device in the rinse water circulation system of dishwashers for cleaning the circulating rinse water. The rinsing water-carrying organs of the device are arranged in such a way that a sieve through which the rinsing water flows, both during operation of the device and when the rinsing water is drained through automatically; the flow of the rinsing water is cleaned.
The drawing shows in Fig. 1. the overall arrangement of an embodiment of the device in vertical section, in Figs. 2 to 4 on an enlarged scale some further embodiments of Siebanord voltage, also in vertical section, all in a schematic representation.
Under the removable bell 1 in Fig. 1, the not shown to rei-nishing dishes is stacked on a frame, also not shown. By means of the spray device 2, water jets are sprayed against the dishes. The draining rinse water collects in the funnel 3 and flows through a pipe connector 4 to the water tank 5. From here it flows through a pipe 6, in which a screw surface 7 is built, into the inlet cavity 8 and the interior of the cylindrical filter 9 .
Due to the screw surface 7, the rinsing water receives an additional rapid rotational movement in addition to the downwardly directed main flow, which takes place at a relatively low speed, so that the screw flow indicated by a winding arrow in the screen interior 8 results from both movements. The rinsing water flows through the openings of the sieve 9 'into the cylindrical drainage cavity 10, which is formed by the sieve 9 and the cylindrical casing 11. A cover 12 with a discharge channel 13 closes the annular space 10 downwards and at the same time holds the sieve 9 in its position.
The upper widened part 14 of the drainage channel 13 serves at the same time as a collecting space for the residues, which are washed away from the inner surface of the sieves 9 by the screw flow in the inlet cavity 8 and conveyed downwards. From the outlet channel 13 carries a drain cock 15, wel cher is closed sen in the position shown.
From the annular space 10, the rinsing water flows through .das pipe 16 to any pump 17 of any type that can be driven. This conveys the rinsing water through a pipe 18 back to the spray device 2, and the cycle of the rinsing water starts again here.
After the dishes have been cleaned, the pump 17 is brought to a standstill and the rinsing water is drained off by opening the tap 15. Now, on the one hand, the rinse water flows from the water tank 5, as before, in a helical manner through the inner space 8 of the sieve downwards, while still taking with it about the inner surface of the sieve 9 adhering rear.
At the same time, however, flows from the spray device 2, from pipe 18, pump 17 and pipe 16, the rinse water located therein back into the annular space 10 and from there through the openings of the sieve 9 into the .Siebinnenraum 8 and, on the other hand, helps through this reverse flow to remove residues adhering to the inner surface of the sieve. The pump 17 must, of course, be of a suitable type, since it allows this backflow when it is at a standstill.
Before the rinsing water can flow out through the tap 15, it first presses the residues that have accumulated in the space 14 out through the tap. By attaching a passage opening 15a of suitable size in the faucet 15 you have it in your hand to drain the drainage of the rinse water at a speed that is as favorable as possible for thorough cleaning of the sieve and the whole device.
The screen arrangements shown in FIGS. 2 and 3 are exemplary embodiments of a simpler design than the arrangement according to FIG. 1.
In Fig. 3, the sieve 9 * is arranged in a position slightly inclined to the horizontal. The inlet cavity 8 is below, the outlet cavity 10 above the sieve 9. The rinsing water passes through the pipe 6 into the space 8, through which it predominantly flows horizontally. The flow has a large movement component Be along the surface of the sieve 9, which conveys the residues retained by the sieve to the collecting chamber 11. After passing through the sieve 91, the rinsing water enters the outlet chamber 10 and flows from there through pipe 16 to the pump. Through the tap 15: residues and rinsing water can be drained.
The arrangement of Fig. 2 is different from the above-described in wesent union only by the vertical arrangement of the screen.
The arrangement of FIG. 3 has the advantage of a very low overall height; in the arrangement according to FIG. 2, the natural sinking movement of the residues, by coinciding with the direction of flow, promotes their separation.
The embodiment of Siebanord voltage according to FIG. 4 combines a relatively low overall height with the use of the very advantageous helical flow. At the same time it is an example \ for the use of the ring cavity surrounding the sieve as an <B> egg </B> inlet cavity.
The rinsing water flows through the pipe 6 tangentially into the annular cavity 8 located between the sieve 9 and the jacket 11, whereby a rotational flow around the sieve 9 arises. The simultaneous relatively slow progress of the liquid in the axial direction of the cylinder annulus creates the ge desired helical flow, which can still be supported by helical ribs 7a in space 8 un. The residues who rinsed the after the collecting chamber 14. The slightly inclined position of the cylinder 11 favors the movement of the residues.
The ribs 7a can be interrupted for the purpose of better flushing from the residues below the screen 9 at 7h or at other points on the circumference. During the axial progression of the flushing water in space 8, the same gradually passes over to the sieve interior 10 and flows from there through pipe 16 to the pump.
