Description

Die vorliegende Erfindung betrifft ein System zum Dosieren eines Behandlungsmittels in einen Reinigungs- oder Desinfektionsautomaten, umfassend einen Behälter, in dem das Behandlungsmittel als zu dosierendes Fluid angeordnet ist, und eine Dosierleitung, die mit dem Desinfektions- oder Reinigungsgerät gegebenenfalls unter Zwischenschaltung einer Dosiereinrichtung verbindbar ist und durch die das zu dosierende Fluid geleitet wird.The present invention relates to a system for dosing a treatment agent in a cleaning or disinfecting machine comprising a container in which the treatment agent is arranged as a fluid to be dosed, and a dosing, which is optionally connectable with the disinfecting or cleaning device with the interposition of a dosing and through which the fluid to be dosed is passed.

Aus der DE 201 15 173 U1 ist ein Dosiergebinde für eine programmgesteuerte Geschirrspülmaschine oder Waschmaschine bekannt, bei dem mehrere auswechselbare Vorratsbehälter mit zu dosierenden Fluiden, wie Reinigungsmittel oder Spülmitteln vorgesehen sind. An den Vorratsbehältern sind abtastbare Identifikationsmarkierungen angeordnet, um die Zuordnung der Behälter zu der jeweiligen Dosierleitung zu ermöglichen. Der Einsatz von Identifikationsmarkierungen durch entsprechende Farbgestaltung ist fehleranfällig, da der Benutzer versehentlich die falsche Dosierleitung anschließen kann. Sofern die Identifikationsmarkierungen mittels Sensoren geprüft werden, ist der Aufbau vergleichsweise aufwendig.From the DE 201 15 173 U1 is a Dosiergebinde for a program-controlled dishwasher or washing machine, in which a plurality of interchangeable reservoir are provided with fluids to be metered, such as detergent or detergent. At the reservoirs scannable identification marks are arranged to allow the assignment of the container to the respective dosing. The use of identification marks by appropriate color design is prone to error, since the user can inadvertently connect the wrong dosing line. If the identification marks are checked by means of sensors, the structure is comparatively expensive.

Es ist daher Aufgabe der vorliegenden Erfindung, ein System zum Dosieren eines Behandlungsmittels in einen Reinigungs- oder Desinfektionsautomaten zu schaffen, das einfach aufgebaut ist und zuverlässig den Anschluss eines falschen Behälters vermeidet.It is therefore an object of the present invention to provide a system for dosing a treating agent in a washer-disinfector which is simple in construction and reliably avoids the connection of a false container.

Diese Aufgabe wird mit einer Dosiereinrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a metering device having the features of claim 1.

Erfindungsgemäß ist an der Dosierleitung eine Absperreinrichtung vorgesehen, die mittels eines mit dem Behälter gekoppelten Kodierstiftes entriegelbar ist, um die Dosierleitung freizugeben. Dadurch kann erreicht werden, dass über mechanische Mittel sichergestellt ist, dass an die Dosierleitung nur derjenige Behälter angeschlossen wird, der den für die Absperreinrichtung vorgesehenen Kodierstift trägt. Denn an den Behälter ist der Kodierstift gekoppelt, der dann zum Entriegeln der Absperreinrichtung benötigt wird. Dies vermeidet eine Fehlbetätigung bei vergleichsweise moderatem Aufwand.According to the invention, a shut-off device is provided on the dosing line, which can be unlocked by means of a coding pin coupled to the container in order to release the dosing line. It can thereby be ensured that it is ensured by means of mechanical means that only one container is connected to the dosing line, which carries the coding pin provided for the shut-off device. Because to the container of the coding pin is coupled, which is then required to unlock the shut-off device. This avoids a faulty operation at a comparatively moderate expense.

Gemäss einer bevorzugten Ausgestaltung der Erfindung ist der Kodierstift an dem Behälter festgelegt und beim Auswechseln des Behälters wird durch den Kodierstift an dem neuen Behälter sichergestellt, dass der korrekte Behälter mit dem entsprechenden Fluid an die Dosierleitung angeschlossen ist. Der Benutzer muss sich somit keine Identifikationsmittel, wie visuelle Kennzeichnungen merken, sondern kann anhand des Kodierstiftes feststellen, ob der Behälter an die korrekte Dosierleitung angeschlossen ist.According to a preferred embodiment of the invention, the coding pin is fixed to the container and when replacing the container, the coding pin on the new container ensures that the correct container with the corresponding fluid is connected to the dosing line. The user thus does not need any means of identification, such as memorizing visual markings, but can determine from the coding pin whether the container is connected to the correct dosing line.

Vorzugsweise umfasst die Absperreinrichtung ein vorgespanntes Klemmelement, über das die Dosierleitung absperrbar ist. Die Dosierleitung kann dabei als flexibler Schlauch ausgebildet sein, der über das Klemmelement abklemmbar ist. Dadurch kann mit einfachen Mitteln eine entsprechende Absperreinrichtung bereitgestellt werden. Das Klemmelement kann dabei über eine Druckfeder vorgespannt sein, die zwischen einem Ventilgehäuse und dem Klemmelement angeordnet ist.Preferably, the shut-off device comprises a prestressed clamping element, via which the metering line can be shut off. The metering line can be designed as a flexible hose, which can be clamped off via the clamping element. As a result, a corresponding shut-off device can be provided by simple means. The clamping element can be biased by a compression spring, which is arranged between a valve housing and the clamping element.

Gemäss einer weiteren Ausgestaltung der Erfindung ist an dem Klemmelement eine Aussparung gebildet, in die der Kodierstift bei entriegeltem Klemmelement einfügbar ist. Die Form der Aussparung muss dann im Wesentlichen mit der Form des Kodierstiftes fluchten, damit das Klemmelement in der entriegelten Position gehalten wird. Durch unterschiedliche Geometrien von Kodierstiften und Aussparungen können unterschiedliche Fluide entsprechend durch eine anders ausgestaltete Absperreinrichtung voneinander getrennt werden. Dabei kann der Kodierstift durch eine Aussparung in einem Ventilgehäuse durchsteckbar sein, so dass sowohl an dem Ventilgehäuse als auch an dem Klemmelement eine entsprechende Aussparung in Form des Kodierstiftes vorhanden sein kann. Zudem kann an dem Klemmelement eine Aussparung zur Durchführung der Dosierleitung vorgesehen sein, so dass die Absperreinrichtung aus nur wenigen Bauteilen hergestellt werden kann.According to a further embodiment of the invention, a recess is formed on the clamping element into which the coding pin can be inserted when the clamping element is unlocked. The shape of the recess then has to be substantially aligned with the shape of the coding pin so that the clamping element is held in the unlocked position. By different geometries of coding pins and recesses different fluids can be separated accordingly by a differently configured shut-off device. In this case, the coding pin can be pushed through a recess in a valve housing, so that both on the valve housing and on the clamping element a corresponding recess in the form of the coding pin can be present. In addition, a recess for carrying out the dosing can be provided on the clamping element, so that the shut-off device can be made of only a few components.

Bei Systemen, in denen mindestens zwei Dosierleitungen zur Dosierung unterschiedlicher Behandlungsmittel verwendet werden, ist es vorteilhaft, wenn diese Dosierleitungen mit Absperreinrichtungen für unterschiedlich ausgebildete Kodierstifte ausgestattet sind. Hierdurch wird sichergestellt, dass die jeweilige Dosierleitung an den richtigen Behälter angeschlossen wird und demzufolge ein Vertauschen der Behälter ausgeschlossen ist. Dies ist insbesondere dann wichtig, wenn eines der Behandlungsmittel ein Desinfektionsmittel ist, da bei einer Zugabe dieses Mittels zum falschen Zeitpunkt der Desinfektionserfolg ausbleibt.In systems in which at least two metering lines are used for metering different treatment agents, it is advantageous if these metering lines are equipped with shut-off devices for differently formed coding pins. This ensures that the respective dosing line is connected to the correct container and therefore a swap of the container is excluded. This is particularly important if one of the treatment agents is a disinfectant, since the addition of this agent at the wrong time the disinfection success fails.

Ein System 1 zum Dosieren eines Behandlungsmittels in einen nicht näher dargestellten Reinigungs- oder Desinfektionsautomaten umfasst einen Behälter 2, in dem das Behandlungsmittel, beispielsweise ein Reinigungsmittel oder ein Desinfektionsmittel, als zu dosierendes Fluid 3 angeordnet ist. Das Fluid 3 kann über eine Sauglanze 4 aus dem Behälter herausgesaugt werden, wobei in einer Platte 5 eines Deckels 6 eine entsprechende Durchführung angeordnet ist. Die Sauglanze 4 ist mit einem Stutzen 7 mit einer Dosierleitung 8 verbunden, die als flexibler Schlauch ausgebildet ist. Die Dosierleitung 8 ist Bestandteil eines Dosiersystems, das mit dem Reinigungs- oder Desinfektionsautomaten verbunden ist. Hierzu kann in dem Automaten, wie beispielsweise aus der DE 201 15 173 U1 bekannt und deshalb hier nicht näher dargestellt, ein Aufnahmeraum für mehrere Behälter angeordnet sein.A system 1 for dosing a treatment agent in a cleaning or disinfection machine, not shown, comprises a container 2, in which the treatment agent, for example a cleaning agent or a disinfectant, is arranged as fluid 3 to be dosed. The fluid 3 can be sucked out of the container via a suction lance 4, wherein a corresponding passage is arranged in a plate 5 of a lid 6. The suction lance 4 is connected to a nozzle 7 with a metering 8, which is designed as a flexible hose. The dosing 8 is part of a dosing system that is connected to the washer or disinfector. For this purpose, in the machine, such as from the DE 201 15 173 U1 known and therefore not shown here in detail, a receiving space for several containers may be arranged.

Die Dosierleitung 8 kann über ein Klemmelement 9 als Absperreinrichtung abgeklemmt werden, die über eine Feder 10 vorgespannt ist. Ferner ist in Figur 1 schematisch ein Kodierstift 11 dargestellt, der an einem Griff 12 des Behälters 2 über ein Seil oder Band festgelegt ist. Nach dem Anschließen der Dosierleitung 8 an die Sauglanze 4 kann somit kein Fluid 3 aus dem Behälter 2 dem Desinfektions- oder Reinigungsgerät zugeführt werden, da zunächst das Klemmelement 9 entriegelt werden muss. Erst wenn der Kodierstift 11 das Klemmelement 9 in der entriegelten Position hält, kann das Fluid zu dem Desinfektions- oder Reinigungsgerät geleitet werden.The dosing line 8 can be clamped off via a clamping element 9 as a shut-off device, which is biased by a spring 10. Furthermore, a coding pin 11 is shown schematically in Figure 1, which is fixed to a handle 12 of the container 2 via a rope or tape. After connecting the dosing 8 to the suction lance 4 thus no fluid 3 can be supplied from the container 2 to the disinfecting or cleaning device, since first the clamping element 9 must be unlocked. Only when the coding pin 11 holds the clamping element 9 in the unlocked position, the fluid can be passed to the disinfecting or cleaning device.

In Figur 2 ist eine Ausgestaltung der Absperreinrichtung dargestellt, bei der zum Abklemmen des Schlauches ein Klemmelement 9 vorgesehen ist, das mit einer Spitze 15 gegen die flexible Dosierleitung 8 drückt. Dadurch wird eine Wand 16 der Dosierleitung 8 gegen eine gegenüberliegende Wand 17 gedrückt, so dass kein Fluid mehr durch die Dosierleitung 8 strömen kann.In Figure 2, an embodiment of the shut-off device is shown, in which for clamping the hose, a clamping element 9 is provided which presses with a tip 15 against the flexible metering line 8. As a result, a wall 16 of the dosing 8 is pressed against an opposite wall 17, so that no fluid can flow through the dosing 8.

Die Dosierleitung 8 ist dabei durch ein Ventilgehäuse 13 geführt, wobei an dem Ventilgehäuse eine Aussparung zur Durchführung der Dosierleitung 8 und an dem Klemmelement 9 eine weitere Durchführung 19 für die Dosierleitung 8 angeordnet ist.The metering line 8 is guided through a valve housing 13, wherein on the valve housing, a recess for the passage of the dosing 8 and on the clamping element 9, a further passage 19 is arranged for the dosing 8.

Das Klemmelement 9 ist dabei durch eine Druckfeder 10 vorgespannt, die einerseits am Klemmelement 9 und andererseits an einem Boden 14 des Ventilgehäuses 13 abgestützt ist. Ohne eine Entriegelung des Klemmelementes 9 bleibt die Dosierleitung 8 somit verschlossen.The clamping element 9 is biased by a compression spring 10, which is supported on the one hand on the clamping element 9 and on the other hand on a bottom 14 of the valve housing 13. Without an unlocking of the clamping element 9, the dosing 8 is thus closed.

An dem Ventilgehäuse 13 ist ferner eine Aussparung 18 für den Kodierstift 11 vorgesehen, der einerseits durch die Aussparung 18 an dem Ventilgehäuse 13 und andererseits an einer Aussparung 20 in dem Klemmelement 9 durchgeführt werden kann.On the valve housing 13, a recess 18 is further provided for the coding pin 11, which can be performed on the one hand by the recess 18 on the valve housing 13 and on the other hand on a recess 20 in the clamping element 9.

Wie in Figur 3 zu sehen ist, muss für den Kodierstift 11 zunächst das Klemmelement 9 über einen Griffabschnitt 21 in das Ventilgehäuse 13 gegen die Kraft der Feder 10 hineingedrückt werden, so dass einerseits die Dosierleitung 8 nicht mehr durch die Spitze 15 des Klemmelementes 9 zusammengedrückt wird und andererseits die Aussparung 20 des Klemmelementes 9 mit der Aussparung 18 des Ventilgehäuses 13 fluchtet. Dadurch kann der zapfenartig ausgebildete Kodierstift 11 in die Aussparungen 18 und 20 eingefügt werden, so dass das Klemmelement 9 in der nach unten gedrückten Position gehalten ist und das Fluid 3 nun durch die Dosierleitung 8 strömen kann.As can be seen in FIG. 3, the clamping element 9 must first be pressed into the valve housing 13 against the force of the spring 10 for the coding pin 11, so that on the one hand the metering line 8 is no longer compressed by the tip 15 of the clamping element 9 On the other hand, the recess 20 of the clamping element 9 is aligned with the recess 18 of the valve housing 13. Thereby, the pin-like formed coding pin 11 can be inserted into the recesses 18 and 20, so that the clamping element 9 is held in the depressed down position and the fluid 3 can now flow through the dosing 8.

Die Aussparungen 18 und 20 sind dabei so gestaltet, dass sie mit der Querschnittsform des Kodierstiftes 11 im Wesentlichen fluchten. Der Kodierstift 11 kann im Querschnitt beispielsweise rechteckig, kreisförmig, dreieckig oder mit einer anderen Form ausgebildet sein, wobei eine Form des Kodierstiftes 11 nur in eine bestimmte Form der Aussparungen 18 und 20 passt. Dadurch kann verhindert werden, dass ein Behälter 2 an die falsche Dosierleitung 8 angeschlossen wird, da der Kodierstift 11 an dem Behälter 2 festgelegt ist und an das entsprechende Klemmelement 9 angebracht werden muss, um eine Durchleitung des Fluids durch die Dosierleitung 8 zu ermöglichen.The recesses 18 and 20 are designed so that they are substantially aligned with the cross-sectional shape of the coding pin 11. The coding pin 11 may be formed in cross section, for example, rectangular, circular, triangular or with another shape, wherein a shape of the coding pin 11 fits only in a certain shape of the recesses 18 and 20. As a result, a container 2 can be prevented from being connected to the wrong metering line 8, since the coding pin 11 is fixed to the container 2 and has to be attached to the corresponding clamping element 9 in order to allow passage of the fluid through the metering line 8.

In Figuren 4 und 5 ist eine modifizierte Ausführungsform einer Absperreinrichtung gezeigt, bei der eine Dosierleitung 8 wieder über ein Klemmelement 9' abgeklemmt werden kann, wobei das Klemmelement 9' über einen Griffabschnitt 21' in ein Ventilgehäuse 13 gegen die Kraft einer Feder gedrückt werden kann. Das Einfügen eines Kodierstiftes 11' erfolgt allerdings von der Seite durch eine Aussparung 20' an dem Ventilgehäuse 13', um das Klemmelement 9' in der nach unten gedrückten Position zu halten und die Dosierleitung 8 freizugeben. Dabei ist an dem Kodierstift 11' ein Griffabschnitt 25 ausgebildet, um die Handhabung zu vereinfachen.FIGS. 4 and 5 show a modified embodiment of a shut-off device in which a dosing line 8 can be disconnected again via a clamping element 9 ', whereby the clamping element 9' can be pressed against a valve spring 13 against the force of a spring via a handle section 21 ' , The insertion of a coding pin 11 ', however, takes place from the side through a recess 20' on the valve housing 13 'in order to hold the clamping element 9' in the depressed position and to release the dosing line 8. In this case, a handle portion 25 is formed on the coding pin 11 'in order to simplify handling.

In Figur 5 ist die geöffnete Position der Absperreinrichtung gezeigt, in der die Dosierleitung 8 durchströmt werden kann. Die Absperreinrichtung mit dem Ventilgehäuse 13 kann dabei an dem Behälter 2 oder einem anderen Bauteil festgelegt werden.In Figure 5, the open position of the shut-off device is shown, in which the dosing 8 can be flowed through. The shut-off device with the valve housing 13 can be fixed to the container 2 or another component.

Es sind verschiedene Ausgestaltungen für die mechanische Entriegelung der Dosierleitung 8 möglich. Ein Kodierstift 11 kann beispielsweise auf eine Rasteinrichtung oder auf ein Ventil wirken, um die Dosierleitung 8 freizugeben. In jedem Fall wird mittels des am Behälter 2 festgelegten Kodierstiftes 11 und des Klemmelementes 9' vermieden, dass ein falsches Fluid durch die Absperreinrichtung geleitet wird.There are various embodiments for the mechanical release of the dosing 8 possible. A coding pin 11 can, for example, act on a latching device or on a valve in order to release the metering line 8. In any case, by means of the coding pin 11 fixed to the container 2 and the clamping element 9 'it is avoided that a wrong fluid is passed through the shut-off device.

Bei Verwendung von zwei oder mehr Dosierleitungen 8 (nicht dargestellt) für verschiedene Behandlungsmittel ist es wichtig, dass alle Klemmelemente 9' unterschiedlich geformte Aussparungen 20' besitzen und demzufolge nur durch den Kodierstift 11' des passenden Behälters 2 in der entriegelten Position gehalten werden können.When using two or more dosing lines 8 (not shown) for different treatment agents, it is important that all clamping elements 9 'have differently shaped recesses 20' and consequently can only be held in the unlocked position by the coding pin 11 'of the mating container 2.
