Description

Die Erfindung betrifft ein Waschgerät zum Reinigen von Teilen wie Maschinenteilen oder dergleichen, mit einem Gehäuse, in dem ein Tank und eine Pumpe angeordnet sind, die über eine Verbindungsleitung Reinigungsflüssigkeit einer Wascheinrichtung zuführt. Die Reinigungsflüssigkeit läuft nach dem Reinigungsvorgang wieder in den Tank zurück, um bei einem nachfolgenden Reinigungsvorgang erneut verwendet zu werden. Meist haben solche Waschgeräte eine Heizeinrichtung in dem Tank, mit dem die Reinigungsflüssigkeit bevorzugt auf ca. 45°C erwärmt wird, wodurch die Teile in dem Waschgerät hochgradig wirksam von den Verschmutzungen gereinigt werden können. Bei derartigen Waschgeräten besteht allgemein das Problem, die Reinigungsflüssigkeit möglichst gründlich von den Verunreinigungen zu befreien, damit sie lang genutzt werden kann, bevor sie gegen neue Reinigungsflüssigkeit ausgetauscht wird. Außerdem ist der Wärmeverlust in vielen Geräten sehr hoch, was sich in erheblichen Energiekosten wiederspiegelt.The invention relates to a washing device for cleaning parts such as machine parts or the like, with a housing in which a tank and a pump are arranged, which supplies cleaning liquid to a washing device via a connecting line. The cleaning liquid returns after the cleaning process back into the tank to be used again in a subsequent cleaning process. Most such washing devices have a heater in the tank, with which the cleaning liquid is preferably heated to about 45 ° C, whereby the parts can be cleaned in the washing device highly effective from the contaminants. In such washing devices, there is generally the problem of cleaning the cleaning fluid as thoroughly as possible from the contaminants so that they can be used for a long time before being replaced with new cleaning fluid. In addition, the heat loss in many devices is very high, which is reflected in significant energy costs.

Aus der EP 2 208 546 B1 ist ein Waschgerät zum Reinigen von Maschinenteilen oder dergleichen bekannt, das eine mit einem aufklappbaren Deckel versehene Waschkabine hat, die durch einen Zwischenboden von dem darunter liegenden Tank getrennt ist. Über dem Zwischenboden ist ein um eine vertikale Achse drehbarer korbähnlicher Teilebehälter angeordnet, in den zu reinigende Teile gelegt werden. Über und unter dem Teilebehälter befinden sich Düsenrohre, deren Strahlen auf den Teilebehälter gerichtet sind. Die Reinigungsflüssigkeit läuft auf dem schräg angeordneten Zwischenboden ab und strömt durch eine Öffnung in dem Zwischenboden in einen Filterkasten und von dort zurück in den Tank. Dieses Waschgerät ist für einen automatischen Reinigungsvorgang von verschmutzten Teilen geeignet, die zuvor in den drehbaren Teilebehälter eingelegt werden.From the EP 2 208 546 B1 a washer for cleaning machine parts or the like is known, which has a hinged lid provided with a washing cabin, which is separated by an intermediate bottom of the underlying tank. About the intermediate bottom a rotatable about a vertical axis basket-like parts container is placed in the parts to be cleaned. Above and below the parts container are nozzle pipes whose jets are directed to the parts container. The cleaning liquid drains on the inclined intermediate bottom and flows through an opening in the Intermediate bottom in a filter box and from there back into the tank. This washer is suitable for automatic cleaning of soiled parts that are previously placed in the rotating parts container.

Wenn Maschinenteile oder dergleichen eine für einen Waschvorgang ungünstige Form haben, beispielsweise enge, tiefe Sackbohrungen oder verwinkelte Formbereiche, können sie durch einen automatischen Waschvorgang durch Strahlen aus Düsenrohren häufig nur unzureichend gereinigt werden, so dass sie von Hand nachgereinigt werden müssen. Dies kann beispielsweise mit Hilfe einer Spritzpistole oder eines Sprühpinsels erfolgen. Die DE 10 2011 109 957 A1 offenbart ein Waschgerät mit einer Waschkabine mit einer Tür mit Sichtscheibe und zwei Eingriffsöffnungen mit Halterungen für Handschuhe oder Stulpen. Eine Bedienungsperson kann bei geschlossener Tür durch die beiden Eingriffsöffnungen hindurch eine Spritzpistole in der Waschkabine betätigen, um von Hand Maschinenteile oder dergleichen zu reinigen. Ein automatischer Waschvorgang ist bei diesem Waschgerät nicht möglich.When machine parts or the like have an unfavorable shape for a washing process, such as narrow, deep blind holes or angled mold areas, they can often be insufficiently cleaned by an automatic washing process by jetting from nozzle pipes, so they must be cleaned by hand. This can be done for example by means of a spray gun or a spray brush. The DE 10 2011 109 957 A1 discloses a washing machine with a washing cubicle with a door with viewing window and two engagement openings with holders for gloves or cuffs. An operator, with the door closed, can actuate a spray gun in the washing booth through the two engaging holes to manually clean machine parts or the like. An automatic washing process is not possible with this washing machine.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Waschgerät anzugeben, das die obigen Nachteile vermeidet.The present invention has for its object to provide a washing device that avoids the above disadvantages.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Die Erfindung sieht vor, dass auf dem Gehäuse eine offene Waschwanne befestigt ist, die einen Sprühpinsel und/oder eine Spritzpistole oder ein ähnliches Reinigungswerkzeug enthält. Die Waschwanne hat an ihrem Boden eine zu öffnende, vorzugsweise schwenkbare Klappe, die etwa so groß ist wie der darunter liegende Tank. Weiter sieht die Erfindung vor, dass unter der Klappe ein Zwischenboden und wenigstens ein Düsenrohr, vorzugsweise zwei einander gegenüber liegende Düsenrohre angeordnet sind, dessen/deren Strahlen auf den Zwischenboden gerichtet sind.The invention provides that an open wash tub is mounted on the housing containing a spray brush and / or a spray gun or a similar cleaning tool. The washing tub has at its bottom an openable, preferably hinged flap, which is about as large as the underlying tank. Next, the invention provides that under the flap, an intermediate bottom and at least one nozzle tube, preferably two opposing nozzle tubes are arranged, whose / their rays are directed to the intermediate bottom.

Damit bietet das erfindungsgemäße Waschgerät die Möglichkeit, in der offenen Waschwanne verschmutzte Maschinenteile oder dergleichen mit dem Sprühpinsel oder der Spritzpistole von Hand zu reinigen und außerdem einen automatischen Reinigungsvorgang durchzuführen, der unter der geschlossenen Klappe abläuft. Diese Reinigungsvorgänge können getrennt voneinander oder auch gleichzeitig ausgeführt werden, wenn die Pumpe eine entsprechende Leistung hat.Thus, the washing device according to the invention offers the possibility to clean in the open washing tub dirty machine parts or the like with the spray brush or the spray gun by hand and also perform an automatic cleaning process that runs under the closed flap. These cleaning operations can be carried out separately or simultaneously, if the pump has a corresponding capacity.

Mit großem Vorteil ist vorgesehen, dass zwischen der geschlossenen Klappe und dem umgebenden Boden der Waschwanne ein Spalt verbleibt und dass unter dem Rand der Klappe ein umlaufender Rücklaufkanal angeordnet ist, der ein Rücklaufloch enthält, unter dem ein Rücklauffilter, vorzugsweise ein Grobfilter angeordnet ist. Die offene Waschwanne ist zweckmäßigerweise in der Vorderansicht des Waschgeräts breiter als das Gehäuse, auf dem sie befestigt ist, so dass zu beiden Seiten der Klappe Platz genug vorhanden ist, um (auch) dort Teile zu reinigen. Der Boden der Waschwanne ist eben und hat eine solche Neigung, dass die Reinigungsflüssigkeit auf dem Boden zu dem Spalt zwischen der Klappe und dem umgebenden Bereich des Bodens fließt und in den umlaufenden Rücklaufkanal fällt, der seinerseits mit einer solchen Neigung versehen ist, dass die gesamte Reinigungsflüssigkeit in das Rücklaufloch und von dort in den Filter und den darunter befindlichen Tank abläuft. Mit Hilfe des Sprühpinsels oder der Spritzpistole ist die Waschwanne nach dem Reinigungsvorgang leicht zu reinigen.With great advantage, it is provided that a gap remains between the closed flap and the surrounding bottom of the washing tub and that a circumferential return channel is arranged below the edge of the flap, which contains a return hole, under which a return filter, preferably a coarse filter is arranged. The open wash tub is conveniently wider in the front view of the washer than the housing on which it is mounted, so there is enough space on either side of the door to clean (even) parts there. The bottom of the washing tub is flat and has such a tendency that the cleaning liquid flows on the floor to the gap between the flap and the surrounding area of the floor and falls into the circulating return channel, which in turn is provided with such a slope that the entire Cleaning liquid drains into the return hole and from there into the filter and the tank underneath. With the help of the spray brush or the spray gun, the washing tub is easy to clean after the cleaning process.

Die automatische Reinigung mittels der aus den Düsenrohren austretenden Wasserstrahlen erfolgt nur bei geschlossener Klappe und ist mit sehr geringen Wärmeverlusten verbunden, da die Reinigungsflüssigkeit entweder direkt in den unter dem Zwischenboden befindlichen Tank zurück läuft oder durch einen unter dem Zwischenboden befindlichen Filter.The automatic cleaning by means of emerging from the nozzle pipes jets of water occurs only with the door closed and is associated with very low heat losses, since the cleaning liquid either runs directly back into the tank located under the false floor or through a filter located under the false floor.

Der Zwischenboden liegt zweckmäßigerweise lose auf Auflagern auf, so dass er einfach entnehmbar ist. Der Zwischenboden hat Löcher und kann beispielsweise durch ein Lochblech oder ein Filtersieb gebildet sein. Darüber kann ein Maschenkorb angeordnet sein. Er hält die zu reinigenden Teile und ermöglicht das ungehinderte Ablaufen der Reinigungsflüssigkeit.The intermediate bottom is expediently loose on supports, so that it is easily removed. The intermediate bottom has holes and can be formed for example by a perforated plate or a filter screen. In addition, a mesh basket can be arranged. It holds the parts to be cleaned and allows unhindered drainage of the cleaning fluid.

Wie bereits erwähnt, kann der automatische Reinigungsvorgang mittels der Düsenrohre nur dann eingeleitet und durchgeführt werden, wenn die Klappe geschlossen ist. Hierzu ist vorgesehen, dass ein Reedschalter die Stellung der Klappe überwacht und mit einem Magnetventil in Verbindung steht, das in die zu den Düsenrohren führende Leitung eingeschaltet ist. Außerdem ist eine Zeitschaltuhr mit dem·Magnetventil verbunden, die einen automatischen Reinigungsvorgang einleiten und durchführen kann, wenn der Reedschalter ein die Schließstellung der Klappe anzeigendes Signal abgegeben hat.As already mentioned, the automatic cleaning process by means of the nozzle tubes can only be initiated and carried out when the flap is closed. For this purpose, it is provided that a reed switch monitors the position of the flap and communicates with a solenoid valve which is connected in the line leading to the nozzle tubes. In addition, a timer is connected to the solenoid valve, which can initiate and perform an automatic cleaning process when the reed switch has issued a signal indicating the closed position of the flap.

In einer Ausführungsform der Erfindung hat das Gehäuse mit dem Tank einen rechteckigen Querschnitt. Eine Pumpe ragt mit dem Ansaugstutzen in den Tank und fördert Reinigungsflüssigkeit durch einen Filter zu der Wascheinheit der offenen Waschwanne oder der automatischen Wascheinheit unter dem Boden der Waschwanne, wobei auch beide Wascheinheiten gleichzeitig mit Reinigungsflüssigkeit versorgt werden können.In one embodiment of the invention, the housing with the tank has a rectangular cross-section. A pump protrudes with the intake into the tank and promotes cleaning fluid through a filter to the washing unit of the open washing tub or the automatic washing unit under the bottom of the washing tub, both washing units can be supplied simultaneously with cleaning liquid.

In einer anderen Ausführungsform hat das Gehäuse mit dem Tank eine kreisrunde Querschnittsform und von der zu den Wascheinheiten führenden Verbindungsleitung zweigt eine weitere Leitung ab, die durch die Gehäusewand und damit durch die Tankwand führt und bevorzugt mit einem kreisbogenförmigen Endabschnitt nahe der Innenwand des Tanks verläuft, um dann, wenn kein Reinigungsvorgang ausgeführt wird, Reinigungsflüssigkeit so in den Tank zurück zu pumpen, dass die in dem Tank befindliche Reinigungsflüssigkeit in Rotation versetzt wird. Hierdurch sammeln sich allmählich die Schmutzpartikel in dem Tank in dessen Zentrum, von wo Reinigungsflüssigkeit mit konzentrierten Schmutzpartikeln durch die in diesem Fall unter dem Boden des Tanks angeordnete Pumpe abgesaugt wird. Dieser Vorgang kann mehrere Stunden dauern und hat zur Folge, dass sich an den Tankwänden praktisch keine Schmutzpartikel ansetzen können. Die Schmutzpartikel werden in dem in die Verbindungsleitung eingeschalteten Filter entfernt.In another embodiment, the housing with the tank has a circular cross-sectional shape and from the connecting line leading to the washing units branches off from another line, which passes through the housing wall and thus through the tank wall and preferably with an arcuate end portion near the inner wall of the tank, to then, if no cleaning operation is performed, pumping cleaning liquid back into the tank in such a way that the cleaning liquid in the tank is set in rotation. As a result, gradually accumulate the dirt particles in the tank in the center, from where cleaning liquid is sucked with concentrated dirt particles through the arranged in this case below the bottom of the tank pump. This process can take several hours and has the result that virtually no dirt particles can attach to the tank walls. The dirt particles are removed in the filter connected in the connecting line.

Die Erfindung sieht somit ein Waschgerät vor, das die Ausführung verschiedenartiger Reinigungsvorgänge von Maschinenteilen oder dergleichen ermöglicht und mit geringen Wärmeverlusten arbeitet. In der bevorzugten Ausführungsform wird zudem der Tank weitestgehend vor Verschmutzung bewahrt.The invention thus provides a washing device that allows the execution of various cleaning processes of machine parts or the like and with low heat losses works. In addition, in the preferred embodiment, the tank is largely preserved from contamination.

Der Boden 4 des Tanks ist wärmeisoliert.The FIGS. 1 and 2 show an embodiment of the washing device, in which a rectangular in plan view of the housing 1 is held on feet 2. Inside the housing 1 is a tank 3, which thus also has a rectangular plan shape. The bottom 4 of the tank is thermally insulated.

Oben auf dem Gehäuse 1 und den Füßen 2 ist eine offene Waschwanne 5 befestigt, die ebenfalls eine rechteckige Grundrißform hat. und in der Frontansicht des Gerätes seitlich über das Gehäuse 1 übersteht. Der Boden 6 der Waschwanne 5 enthält eine rechteckige Aussparung 7 an deren hinteren Rand eine schwenkbare Klappe 8 angelenkt ist. Zwischen der geschlossenen Klappe 8 und dem übrigen Boden 6 der Waschwanne 5 verbleibt entlang der freien Randkanten der Klappe 8 ein kleiner Spalt 9 in der Größenordnung von einigen Millimetern. Der Boden 6 der Waschwanne 5 ist mit einer solchen Neigung versehen, dass die dort befindliche Reinigungsflüssigkeit in den Spalt 9 fließt.On top of the housing 1 and the feet 2, an open washing tub 5 is attached, which also has a rectangular planform. and projects laterally beyond the housing 1 in the front view of the device. The bottom 6 of the washing tub 5 includes a rectangular recess 7 at the rear edge of a pivotable flap 8 is articulated. Between the closed flap 8 and the remaining bottom 6 of the washing tub 5 remains along the free edges of the flap 8, a small gap 9 in the order of a few millimeters. The bottom 6 of the washing tub 5 is provided with such a tendency that the cleaning liquid located there flows into the gap 9.

Die Klappe 8 ist mit einer Klappenarretierung 10 und an ihrer Unterseite mit einem Magneten 11 versehen, der den geschlossenen Zustand der Klappe 8 überwacht. Unter dem Spalt 9 ist ein um die gesamte Aussparung 7 herum umlaufender Rücklaufkanal 12 angeordnet 12, der ein Rücklaufloch 13 enthält, unter dem ein Rücklauffilter 14 befestigt ist. Die den Filter 14 durchströmende Reinigungsflüssigkeit fällt in den Tank 3 zurück.The flap 8 is provided with a flap lock 10 and on its underside with a magnet 11 which monitors the closed state of the flap 8. Under the gap 9 a around the entire recess 7 around circulating return channel 12 is arranged 12 which includes a return hole 13, below which a return filter 14 is attached. The cleaning fluid flowing through the filter 14 falls back into the tank 3.

Unter der Klappe 8 ist ein Zwischenboden 15 angeordnet, der nur lose auf Auflagern aufliegt, so dass er leicht entnommen werden kann. Auf den Zwischenboden 15, der mit Löchern versehen ist, werden zu reinigende Maschinenteile oder dergleichen gelegt, die in einem automatischen Waschvorgang von ihren Verschmutzungen befreit werden sollen. Hierzu befinden sich oberhalb des Zwischenbodens 15 zwei oder mehr einander gegenüber liegende Düsenrohre 16, deren Strahlen auf den Zwischenboden 15 gerichtet sind. Nach Entnahme des Zwischenbodens kann man auch Teile zum Einweichen in die Flüssigkeit eintauchen.Under the flap 8, an intermediate bottom 15 is arranged, which rests only loosely on supports, so that it can be easily removed. On the intermediate bottom 15, which is provided with holes to be cleaned machine parts or the like are laid, which should be freed of their contamination in an automatic washing process. For this purpose, located above the intermediate bottom 15, two or more opposing nozzle tubes 16 whose jets are directed to the intermediate bottom 15. After removal of the false floor you can also dip parts for soaking in the liquid.

In einer neben dem Tank 3 angeordneten, durch eine Tür 17 verschlossenen Gerätekammer 18 ist eine Pumpe 19 angeordnet, deren Saugstutzen 20 durch die Wand des Tanks 3 verläuft und innerhalb des Tanks mit einem Vorfilter 21 versehen ist. Die Pumpe 19 fördert die angesaugt Reinigungsflüssigkeit durch eine Druckleitung zu einem Verteilerblock 22, von dem eine mit einem Magnetventil 23 versehene Zuleitung 24 zu den Düsenrohren 16 führt. Von dem Verteilerblock 22 zweigt außerdem eine Zuleitung 25 zu einem auf dem Boden der Waschwanne 5 angeordneten Verteilerblock 26 ab, der entweder über einen Kugelhahn 27 Reinigungsflüssigkeit einem Reinigungspinsel 28 oder über einen weiteren Kugelhahn 29 einem Gelenkschlauch 30 zuführen kann. Außerdem kann auch eine Spritzpistole über einen zusätzlichen Anschluss angeschlossen werden. Mit Hilfe des Pinsels 28 oder des Gelenkschlauchs 30 sowie gegebenenfalls einer Spritzpistole können Maschinenteile oder dergleichen in der offenen Waschwanne 5 von Hand gereinigt werden. Die Reinigungsflüssigkeit läuft bei geschlossener Klappe 8 durch die Spalte 9, die Rücklaufrinne 12 und den Filter 14 in den Tank 3 zurück.In a arranged next to the tank 3, closed by a door 17 device chamber 18, a pump 19 is arranged, the suction nozzle 20 extends through the wall of the tank 3 and is provided within the tank with a pre-filter 21. The pump 19 conveys the sucked cleaning liquid through a pressure line to a manifold block 22, from which a feed line 24 provided with a solenoid valve 23 leads to the nozzle tubes 16. From the distribution block 22 also branches off a supply line 25 to a arranged on the bottom of the washing tub 5 manifold block 26, which can either a ball valve 27 cleaning liquid a cleaning brush 28 or another ball valve 29 a joint tube 30 perform. In addition, a spray gun can be connected via an additional connection. With the help of the brush 28 or the flexible hose 30 and optionally a spray gun machine parts or the like in the open washing tub 5 can be cleaned by hand. The cleaning liquid runs with the flap 8 closed through the column 9, the return channel 12 and the filter 14 in the tank 3 back.

Bei einem automatischen Reinigungsvorgang, bei dem die Klappe 8 geschlossen sein muss, läuft das aus den Düsenrohren 16 austretende Spritzwasser durch den mit Öffnungen versehenden Zwischenboden 15 hindurch und von dort in den Tank 3 zurück.In an automatic cleaning operation, in which the flap 8 must be closed, the spray water emerging from the nozzle tubes 16 passes through the apertured intermediate shelf 15 and from there back into the tank 3.

Die Wände des Tanks sind zweckmäßigerweise isoliert.The walls of the tank are suitably insulated.

An der Stirnseite des Waschgeräts sind eine Zeitschaltuhr 31, ein Bediendisplay 32, ein Hauptschalter 33 und ein Knietaster 34 zum Einleiten eines automatischen Waschvorgangs angeordnet. Statt eines Knietasters kann auch ein Fußschalter vorgesehen sein.On the front side of the washing machine, a timer 31, an operating display 32, a main switch 33 and a knee switch 34 are arranged to initiate an automatic washing process. Instead of a knee switch and a foot switch can be provided.

Bei der in den Figuren 4 und 5 dargestellten Ausführungsform hat der Tank 35 eine kreisrunde Querschnittsform. Die Wände 36 und der Boden 37 des Tanks 35 sind wärmeisoliert. Die Pumpe 38 befindet sich in einer unter dem Tank 35 angeordneten Pumpenkammer 39 und ist mit ihrem Ansaugstutzen und Vorfilter 40 von unten bündig am Boden des Tanks 35 angeschlossen. Von der Druckleitung 41 der Pumpe zweigt bei dem Verteilerblock 22 eine weitere Zuleitung 42 ab, in die ein Filter 43 eingeschaltet ist. Die Zuleitung 42 führt durch die Wand 36 des Tanks 35 und geht in ein kreisrundes Düsenrohr 44 über, das nahe der Wand 36 des Tanks angeordnet ist. Durch dieses Düsenrohr 44 kann dann, wenn kein Waschvorgang ausgeführt wird, Reinigungsflüssigkeit so in den Tank 35 umgepumpt werden, dass die Reinigungsflüssigkeit in eine Kreisbewegung versetzt wird. Hierdurch wandern die in der Reinigungsflüssigkeit befindlichen Verunreinigungen ins Zentrum der Kreisbewegung, wo sie von dem Ansaugstutzen 40 der Pumpe 38 abgesaugt werden. Der Filter 43 säubert die umlaufende Reinigungsflüssigkeit, so dass sich praktisch keine Schmutzpartikel an den Wänden des Tanks 35 absetzen, so dass die Schmutzpartikel im Filter abgesondert werden und stets ein sauberes Medium zur Verfügung steht. Das Düsenrohr 44 hat einen erheblich kleineren Durchmesser als die Zuleitung 42. Es kann sich auch nur über einen kurzen Kreisbogen erstrecken oder als ein kurzer geradliniger Rohrabschnitt nahe der Tankwand angeordnet sein, um die Reinigungsflüssigkeit in eine Drehbewegung zu versetzen.In the in the FIGS. 4 and 5 illustrated embodiment, the tank 35 has a circular cross-sectional shape. The walls 36 and the bottom 37 of the tank 35 are thermally insulated. The pump 38 is located in a pump chamber 39 arranged below the tank 35 and is connected with its intake manifold and pre-filter 40 from below flush with the bottom of the tank 35. From the pressure line 41 of the pump branches off at the manifold block 22 from another supply line 42, in which a filter 43 is turned on. The supply line 42 passes through the wall 36 of the tank 35 and passes into a circular nozzle tube 44 which is disposed near the wall 36 of the tank. By means of this nozzle tube 44, if no washing process is carried out, cleaning liquid can be pumped into the tank 35 in such a way that the cleaning liquid is set in a circular motion. As a result, the impurities contained in the cleaning fluid migrate to the center of the circular movement, where they are sucked from the intake manifold 40 of the pump 38. The filter 43 cleans the circulating cleaning liquid, so that virtually no dirt particles settle on the walls of the tank 35, so that the dirt particles are separated in the filter and always a clean medium is available. The nozzle tube 44 has a considerably smaller diameter than the feed line 42. It may also extend only over a short circular arc or be arranged as a short rectilinear pipe section near the tank wall in order to set the cleaning liquid in a rotary motion.

Von dem Verteiler 22 zweigen dieselben Zuleitungen zu den Wascheinheiten wie bei der ersten Ausführungsform ab, wobei die hier nicht erwähnten Bauteile und Anordnungen mit denjenigen der ersten Ausführungsform übereinstimmen.From the manifold 22 branch off the same supply lines to the washing units as in the first embodiment, wherein the components and arrangements not mentioned here match those of the first embodiment.
