Description

Die Erfindung betrifft eine Mischvorrichtung für Flüssigkeiten, insbesondere zur Verdünnung von Reinigungs- und Desinfektionskonzentraten mit Wasser in einem definierten Mischungsverhältnis.The invention relates to a mixing device for liquids, in particular for the dilution of cleaning and disinfecting concentrates with water in a defined mixing ratio.

Vorrichtungen der eingangs genannten Art finden unter anderem Anwendung in Großküchen. Zur Reinigung und Desinfektion der Küchen werden unterschiedliche Reinigungs- und Desinfektionsmittel benötigt. Diese werden in der Regel in Form hochwertiger Superkonzentrate zur Verfügung gestellt. Die Verwendung der Superkonzentrate erfolgt dann unter Beimengung von warmem oder kaltem Wasser. Das Mischungsverhältnis des Konzentrates zur Wassermenge ist in der Regel genau vorgegeben. Zur sachgerechten Verwendung ist es daher erforderlich, das vorgegebene Mischungsverhältnis genau einzuhalten. Darüber hinaus besteht auf Seiten der Anwender der Wunsch einer genauen Abmessung, da die Konzentrate teuer sind und die Anwender folglich einen verschwenderischen Einsatz der Konzentrate vermeiden möchten.Devices of the type mentioned are used, inter alia, in commercial kitchens. To clean and disinfect the kitchens, different cleaning agents and disinfectants are needed. These are usually provided in the form of high quality supercontents. The use of the super concentrate is then with the addition of hot or cold water. The mixing ratio of the concentrate to the amount of water is usually specified exactly. For proper use, it is therefore necessary to strictly adhere to the predetermined mixing ratio. In addition, there is a desire on the part of the user for a precise dimension, since the concentrates are expensive and therefore the users want to avoid a wasteful use of the concentrates.

Die Verdünnung der Reinigungs- und Desinfektionsmittel erfolgt im Stand der Technik mit Vorrichtungen, die nach dem so genannten "Venturi-Prinzip" arbeiten. Es handelt sich hierbei um ein Unterdrucksystem, das proportional zur Durchflussmenge arbeitet. Durch den hinter der Venturi-Düse entstehenden Unterdruck, der theoretisch allein von der Durchflussmenge des Wassers abhängt, werden die jeweiligen Mengen an Reinigungs- oder Desinfektionsmittel dem Wasser beigemischt. Die Menge an angesaugtem Reinigungs- oder Desinfektionsmittel ist jedoch auch von anderen Faktoren abhängig, als allein der durchfließenden Wassermenge. So ist die Menge unter anderem von dem jeweiligen Wasserdruck abhängig. Schwankende Wasserdrücke im Leitungssystem führen daher zu einem ungenauen Mischungsverhältnis. Darüber hinaus haben auch Wassertemperatur und Wasserhärte Einfluss auf die zugeführte Konzentratmenge. Durch diese vom jeweiligen Anwender nicht beeinflussbare Faktoren erfolgt die Mischung bei den Vorrichtungen nach dem Stand der Technik ungenau. Hinzu kommt, dass insbesondere bei der Beimengung von Konzentrat in warmem Wasser sich Mehrschwebeteilchen im Wasser befinden, als dies bei kaltem Wasser der Fall ist. Hierbei sind insbesondere Schwebeteilchen in Form von Kalkteilchen zu nennen. Diese haben jedoch die Eigenschaft, mit dem jeweils beigemischten Reinigungs- bzw. Desinfektionsmitteln zusammenzuklumpen. Hierdurch kann es zu Ablagerung in der Düse kommen, die wiederum Einfluss auf den erzeugten Unterdruck haben, der wiederum Einfluss auf die angesaugte Menge an Reinigungs- oder Desinfektionsmittel hat. Im äußersten Fall wird die Düse durch die Ablagerungen verstopft.The dilution of detergents and disinfectants is done in the prior art with devices that operate on the so-called "Venturi principle". It is a vacuum system that works in proportion to the flow rate. Due to the negative pressure arising behind the venturi nozzle, which theoretically depends solely on the flow rate of the water, the respective amounts of cleaning agent or disinfectant are added to the water. However, the amount of sucked cleaning or disinfecting agent is also dependent on other factors, than only the amount of water flowing through. Among other things, the amount depends on the respective water pressure. Varying water pressures in the pipe system therefore lead to an inaccurate mixing ratio. In addition, water temperature and water hardness have an effect on the amount of concentrate supplied. As a result of these factors which can not be influenced by the respective user, the mixing in the devices according to the prior art is carried out inaccurately. In addition, especially in the addition of concentrate in warm water Mehrschwebeteilchen are in the water, as is the case with cold water. In particular, suspended particles in the form of lime particles should be mentioned here. However, these have the property to clump together with the respectively admixed cleaning or disinfecting agents. This can lead to deposits in the nozzle, which in turn have an influence on the generated negative pressure, which in turn has an influence on the sucked amount of detergent or disinfectant. In the extreme case, the nozzle is clogged by the deposits.

Die als Ausführungsbeispiel gewählte Vorrichtung zum Dosieren von Reinigungs- und Desinfektionsmitteln umfasst ein Warmwasser-Leitungssystem 1 und ein Kaltwasser-Leitungssystem 2. Das Warmwasser-Leitungssystem 1 weist im Ausführungsbeispiel zwei und das Kaltwasser-Leitungssystem 2 jeweils vier Abzweigungen auf, die jeweils in Mischventile 3 münden, in denen warmes und kaltes Wasser miteinender mischbar sind. Die Mischventile 3 sind Bestandteil einer - nicht dargestellten - Mischbatterie zur exakten Warmwassertemperatursteuerung. An der Mischbatterie ist eine definierte maximal zulässige Wassertemperatur einstellbar. Die Mischventile 3 stehen jeweils mit einem Proportionalmischer 4 in Verbindung, an dem jeweils ein Behälter 5 für die Aufnahme von Reinigungs- oder Desinfektionskonzentrat angeschlossen ist. Aus jedem Proportionalmischer 4 führt eine Abgabeleitung 6 heraus, die an ihrem freien Ende mit einem Ventil 7 versehen ist. Die gesamte Vorrichtung ist im Ausführungsbeispiel in einem Schrank 8 angeordnet, der aus Edelstahl besteht und abschließbar ist.The selected as an embodiment device for dosing of cleaning and disinfecting agents comprises a hot water pipe system 1 and a cold water pipe system 2. The hot water pipe system 1 has in the embodiment two and the cold water pipe system 2 each four branches, each in mixing valves open, in which hot and cold water are mischbar miteinender. The mixing valves 3 are part of a - not shown - mixer for accurate hot water temperature control. A defined maximum permissible water temperature can be set on the mixer tap. The mixing valves 3 are in each case connected to a proportional mixer 4, to each of which a container 5 for receiving cleaning or disinfecting concentrate is connected. From each proportional mixer 4 performs a discharge line 6, which is provided at its free end with a valve 7. The entire device is arranged in the embodiment in a cabinet 8, which consists of stainless steel and is lockable.

Das Warmwasser-Leitungssystem 1 tritt durch eine Öffnung 81 in den Schrank 8 ein; das Kaltwasser-Leitungssystem 2 tritt durch eine Öffnung 82 in den Schrank 8 ein. Benachbart zu den Öffnungen 81 und 82 sind in den Leitungssystemen 1 und 2 jeweils Systemtrenner 11, 21 angeordnet. Die Systemtrenner 11, 21 sind bei Vorrichtungen der vorliegenden Art vorgeschrieben, um einen Rückfluss von Reinigungs- oder Desinfektionsmittel in die Wasserleitungen, aus denen das warme bzw. kalte Wasser entnommen wird, zu verhindern. Die Leitungssysteme 1, 2 weisen des Weiteren Druckminderer 12, 22 auf, die einen gleichmäßigen Druck in der Vorrichtung gewährleisten und somit einen Schutz gegen Druckschwankungen insbesondere für den Proportionaldosierer 4 bilden. Die Druckminderer 12, 22 sind im Ausführungsbeispiel mit einem Filtersieb auf der Wasserzulaufseite ausgerüstet. Sie können zudem mit einem Manometer versehen sein.The hot water pipe system 1 enters the cabinet 8 through an opening 81; the cold water pipe system 2 enters the cabinet 8 through an opening 82. Adjacent to the openings 81 and 82, system dividers 11, 21 are respectively arranged in the piping systems 1 and 2. The system separators 11, 21 are prescribed in devices of the present type, in order to prevent a backflow of cleaning or disinfecting agent into the water pipes from which the hot or cold water is removed. The line systems 1, 2 furthermore have pressure reducers 12, 22, which ensure a uniform pressure in the device and thus form a protection against pressure fluctuations, in particular for the proportional doser 4. The pressure reducer 12, 22 are equipped in the embodiment with a filter on the water inlet side. They can also be equipped with a pressure gauge.

Die Mischventile 3 sind im Ausführungsbeispiel als Kugelhähne ausgebildet. Sie weisen jeweils zwei Zuläufe auf, von denen der eine für warmes, der andere für kaltes Wasser vorgesehen ist. Die Mischventile 3 weisen weiterhin jeweils einen Ablauf auf, aus dem das aus kaltem und warmem Wasser entstandene Gemisch das jeweilige Mischventil 3 verlässt. Die Einstellung des Mischverhältnisses erfolgt jeweils über einen Betätigungshebel 31.The mixing valves 3 are formed in the embodiment as ball valves. They each have two inlets, one of which is intended for hot, the other for cold water. The mixing valves 3 furthermore each have an outlet, from which the mixture resulting from cold and warm water leaves the respective mixing valve 3. The setting of the mixing ratio takes place via an actuating lever 31.

Der Proportionalmischer 4 weist einen Zulauf für das Mischwasser aus warmem sowie kaltem Wasser und einen Zulauf für das Reinigungs- und Desinfektionskonzentrat auf. Weiterhin ist der Proportionalmischer 4 mit einem Auslauf versehen, an dem die Abgabeleitung 6 angeschlossen ist. Zum Anschluss eines Ansaugschlauches 52 ist an dem Proportionalmischer 4 ein Anschlussstück 41 angeordnet, welches zur stufenlosen Einstellung des gewünschten Mischungsverhältnisses eine Regulierungsschraube mit Feststellring 411 aufweist, die mit einem Saugventil 412 verbunden ist. Das Saugventil 412 ist über eine Saugventilfeder 413 vorgespannt und ist über eine Saugventildichtung 414 gegenüber dem Zulauf 415 des Anschlussstücks 41 abgedichtet. Der Ansaugschlauch 52 ist über einen Anschlusskopf 416 mit dem Anschlussstück 41 verbindbar. Der Proportionalmischer 4 arbeitet prinzipiell wie eine Pumpe. Er beinhaltet im Ausführungsbeispiel einen Kolben, der stromlos betätigbar ist. Der Wasserdruck des den Proportionalmischers 4 durchströmenden Mischwassers wirkt als Antrieb für den Kolben und saugt das Konzentrat aus den Behältern 5. Vor dem Auslauf aus dem Proportionalmischer 4 erfolgt die Mischung des Wassers mit dem Konzentrat in einer integrierten Mischkammer, in der die dosierte Lösung homogenisiert wird. Die Förderleistung der Pumpe ist abhängig vom Volumenstrom des Wassers, das durch den Proportionalmischer 4 fließt. Das Mischverhältnis des Reinigungs- oder Desinfektionsmittelkonzentrats zur Wassermenge muss nach einmaliger Einstellung nicht mehr kontrolliert und nachgestellt werden. Die Menge des Konzentrats bleibt auch bei eventuellen Druck- oder Durchsatzschwankungen konstant und streng proportional zur Wassermenge.The proportional mixer 4 has an inlet for the mixed water of hot and cold water and an inlet for the cleaning and disinfecting concentrate. Furthermore, the proportional mixer 4 is provided with an outlet to which the discharge line 6 is connected. To connect a suction hose 52, a connecting piece 41 is arranged on the proportional mixer 4, which has a regulating screw with locking ring 411 for continuous adjustment of the desired mixing ratio, which is connected to a suction valve 412. The suction valve 412 is biased by a Saugventilfeder 413 and is sealed via a Saugventildichtung 414 opposite the inlet 415 of the fitting 41. The intake hose 52 can be connected to the connection piece 41 via a connection head 416. The proportional mixer 4 operates in principle like a pump. It includes in the exemplary embodiment a piston which can be actuated without current. The water pressure of the mixed water flowing through the proportional mixer 4 acts as a drive for the piston and sucks the concentrate from the containers 5. Before leaving the proportional mixer 4, the mixture of water with the concentrate takes place in an integrated mixing chamber in which the metered solution is homogenized , The delivery rate of the pump is dependent on the volume flow of the water flowing through the proportional mixer 4. The mixing ratio of the detergent or disinfectant concentrate to the amount of water does not need to be checked and readjusted after a single adjustment. The amount of concentrate remains constant and strictly proportional to the amount of water even in case of pressure or throughput fluctuations.

Bei den Behältern 5 handelt es sich in der Regel um handelsübliche Kanister, in denen die Reinigungs- und Desinfektionskonzentrate von den Herstellern angeboten werden. Die Gebindegrößen können beliebig sein, wobei Größen bis zu 10 kg überwiegend Anwendung finden. Die Behälter 5 weisen jeweils eine Öffnung 51 auf. Über einen Ansaugschlauch 52 stehen die Behälter 5 mit dem Proportionalmischer 4 in Verbindung. Es ist dabei nicht erforderlich, die Ansaugschläuche 52 an den Behältern 5 zu befestigen; vielmehr ist es ausreichend, die Ansaugschläuche 52 durch die Öffnungen 51 der Behälter 5 in diese einzuhängen. Die Ansaugschläuche 52 weisen hierzu an ihrem Ende ein Rückschlagventil mit einem Gewicht 53 auf, wodurch ein unbeabsichtigtes Ansaugen von über dem Konzentratfüllpegel befindlicher Luft vermieden ist. Aufgrund der gesicherten Unterbringung der Behälter 5 in dem Schrank 8 besteht nicht die Gefahr, dass die Ansaugschläuche 52 versehentlich aus den Behältern 5 entfernt werden.The containers 5 are usually commercially available canisters in which the cleaning and disinfecting concentrates are offered by the manufacturers. The container sizes can be arbitrary, with sizes up to 10 kg predominantly apply. The containers 5 each have an opening 51. Via a suction hose 52, the container 5 are connected to the proportional mixer 4 in connection. It is not necessary to attach the suction hoses 52 to the containers 5; rather, it is sufficient to suspend the suction tubes 52 through the openings 51 of the container 5 in this. The suction hoses 52 have for this purpose at their end a check valve with a weight 53, whereby an inadvertent suction of over the Konzentratfüllpegel air is avoided. Due to the secure placement of the container 5 in the cabinet 8 there is no risk that the suction hoses 52 are accidentally removed from the containers 5.

Die Abgabeleitung 6 führt von dem Proportionaldosierer 4 zu dem Boden des Schrankes 8, in dem Öffnungen 83 für den Austritt der Leitungen 6 vorgesehen sind. Im Bereich der Öffnungen 83 sind die Ventile 7 angeordnet, über die die Entnahme der dosierten Lösung absperrbar ist. Die Ventile 7 sind mit Anschlüssen 71 für Reinigungsschläuche versehen. Hierdurch ist einerseits die Möglichkeit geschaffen, die dosierte Lösung direkt in eine Heißwasserpistole 72 zu führen und so direkt aus der Vorrichtung die dosierte Lösung auf die zu reinigenden Flächen aufzubringen. Im Ausführungsbeispiel sind die Anschlüsse 71 als Schnellkupplung ausgeführt. Andererseits kann über die Ventile 7 die dosierte Lösung auch in einen Eimer oder eine Gießkanne angefüllt werden.The discharge line 6 leads from the proportional meter 4 to the bottom of the cabinet 8, in which openings 83 are provided for the exit of the lines 6. In the region of the openings 83, the valves 7 are arranged, via which the removal of the metered solution can be shut off. The valves 7 are provided with connections 71 for cleaning hoses. As a result, on the one hand, the possibility is created to lead the metered solution directly into a hot water gun 72 and so applied directly from the device, the metered solution to the surfaces to be cleaned. In the exemplary embodiment, the terminals 71 are designed as a quick coupling. On the other hand, via the valves 7, the metered solution can also be filled in a bucket or a watering can.
