Definitions
- the invention relates to a metering system for flowable washing or cleaning agents with the features of the preamble of claim 1.
- Dishwashing detergents are available to consumers in a variety of forms. In addition to the traditional liquid hand dishwashing detergents, machine dishwashing detergents have become particularly important with the spread of household dishwashing machines. These machine dishwashing agents are typically offered to the consumer in solid form, for example as powder or as tablets, but increasingly also in liquid form. For some time now, the main focus has been on the convenient dosage of detergents and cleaning agents and the simplification of the work steps required to carry out a washing or cleaning process. Similar questions also arise with household washing machines.
- one of the main goals of the manufacturers of machine cleaning agents is to improve the cleaning performance of these agents, with a recent focus on cleaning performance in low-temperature cleaning cycles or in cleaning cycles with reduced water consumption.
- new ingredients for example more effective surfactants, polymers, enzymes or bleaching agents, were preferably added to the cleaning agents.
- new ingredients are only available to a limited extent and the amount of ingredients used per cleaning cycle cannot be increased to any extent for ecological and economic reasons, there are natural limits to this approach.
- the starting point for the teaching of the present invention is a metering system according to the WO 2010/006761 A2 .
- EP 0 268 451 A2 Another dosing system is out EP 0 268 451 A2 is known, this further metering system having a cartridge and a receiving module for the cartridge, wherein a triggering means connected to a reset switch is provided in the receiving module, so that the reset switch is actuated by removing an empty cartridge and coupling a new cartridge via the triggering means and thereby a pump control, not shown, is triggered.
- the teaching of the present invention is based on the problem of providing a metering system which is improved with regard to handling in daily operation. To provide the dosing system.
- the metering device of the metering system for flowable detergents or cleaning agents has a housing and an energy source and an electronic control unit are provided in the housing.
- the metering device can include an actuator which is connected to the energy source and the control unit in such a way that a control signal from the control unit causes the actuator to move.
- a closure element is actuated by the actuator, which closes the outlet of a metering chamber in the metering device or releases.
- the dosing chamber in the dosing device is then communicatively connected to at least one cartridge chamber of the cartridge in the assembled state of the dosing device and cartridge, and the dosing chamber has an inlet for the inflow of washing or cleaning agent from the cartridge chamber and an outlet for the outflow of the washing or cleaning agent in dosed form from the dosing chamber into the environment.
- the electronic control unit serves to control the dosing process of the dosing device for the detergent or cleaning agent.
- the control unit is used to implement the method for operating the metering device.
- at least one dosing program is stored in the control unit.
- the control unit controlled by the dosing program, interacts with at least one actuator located in the dosing device in such a way that the flowable washing or cleaning agent is released from the dosing device into the interior of the household appliance, in particular thus into the interior of the dishwasher.
- the detergent is dosed from the cartridge once or several times in a predetermined amount from the cartridge during a specific device cycle.
- the control unit controls the dosing device in such a way that when the device is used several times, in particular the dishwasher, the dosing cycle always runs accordingly.
- control unit keeps track of how many cycles have been processed by the dosing device with the existing cartridge. This can be used to determine whether the cartridge needs to be replaced.
- this control unit has a reset switch.
- the dosing device can also have a separate reset switch, which is then connected to the control unit. It is essential that the control unit is set in terms of circuitry in such a way that actuation of the reset switch in the control unit leads to a reset control signal.
- the term “set in terms of circuit technology” normally does not mean a fixed specification in terms of circuit technology, but in particular corresponding programming of the control unit.
- the reset switch is now designed according to the invention so that it is itself reset.
- the reset switch By coupling a cartridge to the dosing device, the reset switch is actuated so that it leads to the reset control signal.
- the reset switch When the cartridge is detached from the dosing device, the reset switch is released again and resets itself.
- This reset control signal in the control unit can be used to generate switching functions in or by the control unit.
- a special switching function that is particularly preferred according to the invention is that a counter for dosing cycles of the dosing device is reset when the reset control signal occurs.
- the reset value of the counter is preferably the setting value for a new cartridge with a filled cartridge chamber.
- the metering device of the metering system can also be designed in such a way that the control unit has a cartridge emptying sensor or is connected to one. This can then be used to monitor the filling status of a cartridge coupled to the dosing device.
- the reset control signal initiated by the reset switch can be used, for example, to activate the cartridge emptying sensor.
- the reset switch can also be used for a further function, namely in such a way that the control unit is set in terms of circuitry so that the reset control signal serves simultaneously as a switch-on signal for the control unit as a whole or for parts of the control unit that consume significant energy, so that when the reset switch is reset, the control unit total or the essential energy-consuming parts of the control unit are switched off. If, on the other hand, the reset switch is not switched on - directly or indirectly - in the supply circuit of the control unit or in parts of the control unit that consume significant energy, essential functions of the electronic control unit can also be carried out when the reset switch is reset. However, this also increases the energy consumption of the control unit.
- the reset switch as an electromechanical switch with a spring-loaded mechanical switching rocker or the like, one with the switching rocker or the like. movable, electrical or magnetic influencing element and a sensor that can be influenced in or on the control unit.
- the reset switch as a magnetic switch, in particular as a reed switch, with a magnetic field-sensitive sensor in or on the control unit and an influencing magnet that is adjustable against it.
- Such an electromechanical or mechanical / magnetic construction can also be made reliable, for example in the interior of a dishwasher, in a moist environment.
- a construction with a pivotable cartridge is provided.
- a coupling which is preferably designed as a recess, for coupling the cartridge is provided at one end of the connection section of the housing.
- a particularly expedient embodiment of the invention is selected such that the reset switch is arranged at the opposite end of the connection section of the housing. The reset switch is only activated when the cartridge is finally snapped into the dispenser, because it is only then that it is reached by the corresponding area of the cartridge.
- an actuating element for a reset switch of the metering device is arranged and / or configured on the cartridge such that the actuating element becomes ineffective, in particular breaks off, when the cartridge is released from the metering device.
- the reset switch is actuated. If the cartridge is released, the cartridge is changed so that the reset switch can no longer be actuated when the cartridge is connected again.
- Corresponding information can then be derived from this for the control unit. In particular, the control unit may not be switched on. The user notices that he has made a mistake and replaces the partially empty cartridge with a new, functional cartridge.
- the dosing system according to the invention is particularly suitable for use in water-bearing household appliances such as dishwashers or washing machines. However, use is not limited to such use.
- Fig. 1 First shows a large household appliance, here in the form of a dishwasher 1 with an interior, which is accessible in this illustration because of the front door 2 folded down.
- a drawer 3 shown as a dish holder basket, in which there is a dosing system 4 according to the invention.
- the dosing system 4 can in principle be positioned anywhere within the drawer 3 of the dishwasher 1. It is advantageous to have a metering system 4 shaped like a plate, so that it can be set in a corresponding plate holder of the drawer 3.
- a dosing chamber is indicated on the front door 2 of the dishwasher 1, into which a detergent tablet or the like. can be entered.
- the dosing system 4 according to the invention is located inside the dishwasher 1, it is not necessary to use the dosing chamber since the detergent or cleaning agent is dispensed into the interior of the dishwasher by the dosing system 4.
- Indicated display and / or control elements 9 are located on the front of the housing 6, which display the operating state of the metering device 5 and / or can act on it.
- connection section 10 here formed as a peripheral edge, for the detachable coupling of a cartridge 11 shown above the metering device 5.
- This cartridge 11 is therefore shown here detached from the metering device 5.
- the cartridge 11 has at least one cartridge chamber 12.
- the cartridge 11 has two cartridge chambers 12, so that two different flowable detergents or cleaning agents can be stored.
- the WO 2010/006761 A2 explains very extensively what these washing or cleaning agents are typically and what the compositions are. In this respect, reference may also be made to the state of the art.
- outlet openings 13 of the cartridge chambers 12 are found on each of the two cartridge chambers 12.
- Dosing chamber inlets 14 on the top of the housing 6 of the metering device 5 correspond to the outlet openings 13 of the cartridge chambers 12 of the cartridge 11.
- the metering chamber inlets 14 also have means which, when the cartridge 11 is plugged / coupled onto the housing 6 of the metering device 5, open the outlet openings 13 cause so that in the coupled state of cartridge 11 and metering device 5, the interior of the cartridge chambers 12 is communicatively connected to the metering chamber inlets 14.
- Fig. 2 shows on the right the situation that exists when the cartridge 11 is coupled to the metering device 5. Here the dosing system 4 is complete and ready for operation.
- FIG Fig. 3 and 4 A more detailed implementation of a dosing system 4 is shown in FIG Fig. 3 and 4 , There you can also see more precise details of the various cartridge chambers 12 of the cartridge 11, the outlet openings 13 and the metering chamber inlets 14 Fig. 3 and 4 in the metering device 5 below the metering chamber inlets 14, the metering chambers 15 with associated actuators 16 and closure elements 17. All of this is shown in detail in the WO 2010/006761 A2 described and so far requires no further detailed explanation.
- Fig. 3 and 4 can be seen in the left half of the housing 6 of the metering device 5, the control unit 8 with the energy source 7, all shown schematically.
- the control unit has a reset switch 18 or is connected to it.
- the reset switch 18 is self-resetting, is actuated by coupling a cartridge 11 to the metering device 5 and is released when the cartridge 11 is released and then resets itself.
- the control unit 8 is set in such a way that actuation of the reset switch 18 in the control unit 8 leads to a reset control signal. This can be used in the system for control purposes.
- the term “set in terms of circuit technology” today means primarily that control unit 8 is programmed accordingly.
- a reset control signal is generated in the control unit 8 which supplies the information as to whether a cartridge 11 is coupled to the metering device 5 or not. This information can be used in the control unit 8 in various ways.
- a first and particularly essential form of using the reset control signal is that the control unit 8 has a counter for dosing cycles of the dosing device 5 and the counter is reset when the reset control signal occurs, the reset value of the counter preferably being the setting value for corresponds to a new cartridge 11 with a filled cartridge chamber 12.
- counter in this context means any type of electronic or programmed device, the measured value of which can be changed or changed depending on the number of metering cycles that have elapsed. In particular, this is just a counter in the narrower sense.
- the reset control signal that is generated when a new cartridge 11 is attached to the dosing device 5 means that the reset value of the counter is the setting value for a new cartridge 11 with a completely filled cartridge chamber 12.
- the metering device 5 or its control unit 8 thus has the information that a filled cartridge 11 can be assumed and the full number of expected metering cycles can be processed.
- the control unit 8 can thus use the counter to determine independently whether the coupled cartridge 11 is still full, already partially emptied or almost completely emptied and must be replaced. Accordingly, the control unit 8 can emit a signal, in particular via the display or control elements 9 on the housing 6 of the metering device 5.
- the reset switch 18 can take on a further function, namely in such a way that the control unit 8 is set in terms of circuitry in such a way that the reset control signal simultaneously serves as a switch-on signal for the control unit 8 as a whole or for parts of the control unit 8 that consume significant energy, so that when the reset switch is reset 18 the control unit 8 as a whole or the essential energy-consuming parts of the control unit 8 are switched off.
- control unit 8 the essential energy-consuming parts of the control unit 8 are switched off when the reset switch 18 is reset.
- Some essential functions of the cartridge 11 that are also required in the absence of a cartridge Control unit 8 can be retained, in particular also the function of switching control unit 8 on when the reset switch 18 is actuated.
- control unit 8 has a reset switch 18 or is connected to it.
- the reset switch can therefore initially be a complete part of the control unit 8. This can be done with an electronic, capacitive or inductive proximity switch, for example.
- Such constructions are not optimal in the environment of a dishwasher with the very humid ambient atmosphere.
- the metering device 5 has a reset switch 18 connected to the control unit 8, which is designed as an electromechanical switch.
- the reset switch 18 has a spring-loaded mechanical rocker switch 19 or another, similar mechanical actuating element.
- This rocker switch 19 or the like is arranged in a suitable place in the housing 6 of the metering device 5.
- An electrical or magnetic influencing element 20 is movable with the rocker switch 19.
- the reset switch 18 is designed as a magnetic switch, in particular as a reed switch.
- the sensor 21 is a magnetic field sensitive sensor, which is preferably arranged in the control unit 8 protected from moisture. A Hall sensor is particularly recommended here.
- an influencing magnet which here represents the influencing element 20 of the reset switch 18, is adjustable.
- FIG. 3 and 4 the drawing only indicate the reset switch 18.
- Fig. 5 and 6 The drawing shows the reset switch 18 in a greatly enlarged illustration at the left end of the housing 6.
- Fig. 5 shows the position of the reset switch 18 when no cartridge 11 is attached, ie reset.
- the encapsulated control unit 8 with the Hall sensor located therein can be seen on the right as the sensor 21 of the control unit 8.
- On the left of the wall of the control unit 8 one can see the influencing magnet, which here represents the influencing element 20 of the reset switch 18. It is located on the right arm of a rocker switch 19 which is pivotally mounted in the housing 6 of the metering device 5 by means of the pivot axis 19 '.
- a spring element 19 is integrally formed on the rocker switch 19", which the rocker switch 19 normally in the in Fig. 5 Preset position shown biased. The further arm of the The rocker switch 19 is moved from the downwardly projecting edge 22 of the cartridge 11 when the cartridge 11 is coupled to the housing 6.
- the cartridge 11 is in Fig. 5 and 6 not shown. Fig. 6 but shows the position of the upstanding arm of the rocker switch 19 as it is taken when the cartridge 11 has been coupled to the housing 6 and the edge 22 has pressed this arm of the rocker switch 19 to the left against the wall of the housing 6.
- the reset switch 18 is therefore composed of a mechanical component, namely the rocker switch 19 with its components, a magnetic component, namely the influencing magnet 20, and an electronic component, namely the Hall sensor 21.
- the reset switch 18 can also be composed of other components, for example can have only one component in a targeted manner.
- the particularly preferred and special exemplary embodiment of a metering system 4 according to the invention is particularly characterized in that the metering device 5 at the connection section 10 of the housing 6 is provided at one end with a coupling, preferably designed as a recess 23, for coupling the cartridge 11 and that the reset switch 18 is on opposite end of the connection section 10 of the housing 6 is arranged.
- a coupling preferably designed as a recess 23
- the reset switch 18 is on opposite end of the connection section 10 of the housing 6 is arranged.
- the indentation 24 is approximately semicircular and has a shoulder at its bottom end.
- the indentation 24 with the shoulder is configured such that the shoulder can be inserted into the recess 23 on the housing 6 by pivoting the cartridge 11 when the cartridge 11 is coupled to the housing 6 of the metering device 5.
- a targeted, precisely defined, sequential coupling of the outlet openings 13 of the successive cartridge chambers 12 to the metering chamber inlets 14 of the metering device 5 takes place WO 2010/006761 A2 advantages explained in detail.
- the in Fig. 3 and 4 The latching elements 25 and 26 indicated on the left on the cartridge 11 and on the metering device 5 the cartridge 11 in the coupled position.
- These snap-in elements 25, 26 are designed such that they can be released again by a user, for example by compressing a clip-like snap-in element 26 on the metering device 5 Fig. 4 directional pivoting movement, the cartridge 11 can then be separated from the metering device 5 again.
- the reset switch 18 is arranged at the end of the housing 6 which lies opposite the end forming the swivel connection.
- the reset switch 18 is therefore only actuated at the very end, when the cartridge 11 is fully engaged. In this way, incorrect actuation of the reset switch 18 can be avoided.
- an actuating element for a reset switch 18 of the metering device 5 is arranged and / or configured on the cartridge 11 such that the actuating element becomes ineffective when the cartridge 11 is detached from the metering device 5, in particular aborts.
- the actuating element for the reset switch 18 is then unusable. A renewed coupling of the cartridge 11 to the housing 6 has no effect with regard to the control unit 8. In particular, if the reset switch 18 also has an overall influence on the activation of the control unit 8, this is a very effective protective measure.

Die Erfindung betrifft ein Dosiersystem für fließfähige Wasch- oder Reinigungsmittel mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a metering system for flowable washing or cleaning agents with the features of the preamble of
Geschirrspülmittel stehen dem Verbraucher in einer Vielzahl von Angebotsformen zur Verfügung. Neben den traditionellen flüssigen Handgeschirrspülmitteln haben mit der Verbreitung von Haushaltsgeschirrspülmaschinen insbesondere die maschinellen Geschirrspülmittel eine große Bedeutung. Diese maschinellen Geschirrspülmittel werden dem Verbraucher typischerweise in fester Form, beispielsweise als Pulver oder als Tabletten, zunehmend jedoch auch in flüssiger Form angeboten. Ein Hauptaugenmerk liegt dabei seit geraumer Zeit auf der bequemen Dosierung von Wasch- und Reinigungsmitteln und der Vereinfachung der zur Durchführung eines Wasch- oder Reinigungsverfahrens notwendigen Arbeitsschritte. Ähnliche Fragen treten auch bei Haushalts-Waschmaschinen auf.Dishwashing detergents are available to consumers in a variety of forms. In addition to the traditional liquid hand dishwashing detergents, machine dishwashing detergents have become particularly important with the spread of household dishwashing machines.

Similar questions also arise with household washing machines.
Ferner ist eines der Hauptziele der Hersteller maschineller Reinigungsmittel die Verbesserung der Reinigungsleistung dieser Mittel, wobei in jüngster Zeit ein verstärktes Augenmerk auf die Reinigungsleistung bei Niedrigtemperatur-Reinigungsgängen bzw. in Reinigungsgängen mit verringertem Wasserverbrauch gelegt wird. Hierzu wurden den Reinigungsmitteln vorzugsweise neue Inhaltsstoffe, beispielweise wirksamere Tenside, Polymere, Enzyme oder Bleichmittel zugesetzt. Da neue Inhaltsstoffe jedoch nur in begrenztem Umfang zur Verfügung stehen und die pro Reinigungsgang eingesetzte Menge der Inhaltsstoffe aus ökologischen und wirtschaftlichen Gründen nicht in beliebigem Maß erhöht werden kann, sind diesem Lösungsansatz natürliche Grenzen gesetzt.Furthermore, one of the main goals of the manufacturers of machine cleaning agents is to improve the cleaning performance of these agents, with a recent focus on cleaning performance in low-temperature cleaning cycles or in cleaning cycles with reduced water consumption. For this purpose, new ingredients, for example more effective surfactants, polymers, enzymes or bleaching agents, were preferably added to the cleaning agents. However, since new ingredients are only available to a limited extent and the amount of ingredients used per cleaning cycle cannot be increased to any extent for ecological and economic reasons, there are natural limits to this approach.
In diesem Zusammenhang sind in jüngster Zeit insbesondere Vorrichtungen zur Mehrfachdosierung von Wasch- und Reinigungsmitteln in das Blickfeld der Produktentwickler geraten. Bei diesen Vorrichtungen kann zwischen in die Geschirrspülmaschine oder Textilwaschmaschine integrierten Dosierkammern einerseits und eigenständigen, von der Geschirrspülmaschine oder Textilwaschmaschine unabhängigen Vorrichtungen andererseits unterschieden werden. Mittels dieser Vorrichtungen, welche ein Mehrfaches der für die Durchführung eines Reinigungsverfahrens notwendigen Reinigungsmittelmenge enthalten, werden Wasch- oder Reinigungsmittelportionen in automatischer oder halbautomatischer Weise im Verlauf mehrerer aufeinander folgender Reinigungsverfahren in den Innenraum der Reinigungsmaschine dosiert. Für den Verbraucher entfällt die Notwendigkeit der manuellen Dosierung bei jedem Reinigungs- bzw. Waschgang.In this context, devices for multiple dosing of detergents and cleaning agents have recently come into the focus of product developers. In these devices, a distinction can be made between metering chambers integrated in the dishwasher or textile washing machine on the one hand and independent devices independent of the dishwasher or textile washing machine on the other hand. Using these devices, which contain a multiple of the amount of detergent required to carry out a cleaning process, detergent or cleaning agent portions dosed into the interior of the cleaning machine in an automatic or semi-automatic manner in the course of several successive cleaning processes. The consumer no longer needs to dose manually with every cleaning or washing cycle.

Bevorzugte Ausgestaltungen und Weiterbildungen eines solchen Dosierystems sind Gegenstand der Unteransprüche.The problem presented above is first solved with a metering system with the features of the preamble of
Wesentlich für die Lehre der vorliegenden Erfindung ist zunächst nur, dass das Dosiergerät des Dosiersystems für fließfähige Wasch- oder Reinigungsmittel ein Gehäuse aufweist und im Gehäuse eine Energiequelle und eine elektronische Steuereinheit vorgesehen ist. Wie in der den Ausgangspunkt für die Lehre darstellenden Quelle beschrieben wird, kann das Dosiergerät einen Aktuator beinhalten, der derart mit der Energiequelle und der Steuereinheit verbunden ist, dass ein Steuersignal der Steuereinheit eine Bewegung des Aktuators bewirkt. Vom Aktuator wird ein Verschlusselement betätigt, das den Auslass einer Dosierkammer im Dosiergerät verschließt oder freigibt. Die Dosierkammer im Dosiergerät ist dann im zusammengesetzten Zustand von Dosiergerät und Kartusche mit mindestens einer Kartuschenkammer der Kartusche kommunizierend verbunden, und die Dosierkammer weist einen Einlass für das Einströmen von Wasch- oder Reinigungsmittel aus der Kartuschenkammer und einen Auslass für das Ausströmen des Wasch-oder Reinigungsmittels in dosierter Form aus der Dosierkammer in die Umgebung auf.It is only essential for the teaching of the present invention that the metering device of the metering system for flowable detergents or cleaning agents has a housing and an energy source and an electronic control unit are provided in the housing. As described in the source representing the starting point for the teaching, the metering device can include an actuator which is connected to the energy source and the control unit in such a way that a control signal from the control unit causes the actuator to move. A closure element is actuated by the actuator, which closes the outlet of a metering chamber in the metering device or releases. The dosing chamber in the dosing device is then communicatively connected to at least one cartridge chamber of the cartridge in the assembled state of the dosing device and cartridge, and the dosing chamber has an inlet for the inflow of washing or cleaning agent from the cartridge chamber and an outlet for the outflow of the washing or cleaning agent in dosed form from the dosing chamber into the environment.
Die elektronische Steuereinheit dient dazu, den Dosierprozess des Dosiergerätes für das Wasch- oder Reinigungsmittel zu steuern. Die Steuereinheit dient dazu, das Verfahren zum Betrieb des Dosiergerätes umzusetzen. Dazu ist in der Steuereinheit wenigstens ein Dosierprogramm gespeichert. Die Steuereinheit wirkt, gesteuert vom Dosierprogramm, mit wenigstens einem im Dosiergerät befindlichen so Aktuator zusammen, dass das fließfähige Wasch- oder Reinigungsmittel vom Dosiergerät ins Innere des Haushaltsgerätes freigesetzt wird, insbesondere also ins Innere der Geschirrspülmaschine. Auf diese Weise wird durch das Dosiergerät aus der Kartusche während eines bestimmten Gerätezyklus das Wasch- oder Reinigungsmittel einmal oder mehrfach in vorgegebener Menge dosiert. Außerdem steuert die Steuereinheit das Dosiergerät so, dass bei mehrfacher Benutzung des Gerätes, insbesondere der Geschirrspülmaschine, der Dosierzyklus immer wieder entsprechend abläuft.The electronic control unit serves to control the dosing process of the dosing device for the detergent or cleaning agent. The control unit is used to implement the method for operating the metering device. For this purpose, at least one dosing program is stored in the control unit. The control unit, controlled by the dosing program, interacts with at least one actuator located in the dosing device in such a way that the flowable washing or cleaning agent is released from the dosing device into the interior of the household appliance, in particular thus into the interior of the dishwasher. In this way, the detergent is dosed from the cartridge once or several times in a predetermined amount from the cartridge during a specific device cycle. In addition, the control unit controls the dosing device in such a way that when the device is used several times, in particular the dishwasher, the dosing cycle always runs accordingly.
Mittels eines Zählers oder einer äquivalenten, einem Zähler in der Wirkung entsprechenden Einrichtung in der Steuereinheit vollzieht die Steuereinheit nach, wie viele Zyklen vom Dosiergerät mit der vorhandenen Kartusche abgearbeitet worden sind. Daraus lässt sich ermitteln, ob die Kartusche ausgewechselt werden muss.By means of a counter or an equivalent device in the control unit corresponding to a counter in effect, the control unit keeps track of how many cycles have been processed by the dosing device with the existing cartridge. This can be used to determine whether the cartridge needs to be replaced.
Erfindungsgemäß ist es nun so, dass diese Steuereinheit einen Resetschalter aufweist. Das Dosiergerät kann auch einen separaten Resetschalter aufweisen, der dann mit der Steuereinheit verbunden ist. Dabei ist wesentlich, dass die Steuereinheit schaltungstechnisch so eingestellt ist, dass eine Betätigung des Resetschalters in der Steuereinheit zu einem Reset-Steuersignal führt. Der Begriff "schaltungstechnisch eingestellt" bedeutet heutzutage normalerweise keine schaltungstechnisch feste Vorgabe, sondern insbesondere eine entsprechende Programmierung der Steuereinheit.According to the invention, this control unit has a reset switch. The dosing device can also have a separate reset switch, which is then connected to the control unit. It is essential that the control unit is set in terms of circuitry in such a way that actuation of the reset switch in the control unit leads to a reset control signal. Nowadays, the term "set in terms of circuit technology" normally does not mean a fixed specification in terms of circuit technology, but in particular corresponding programming of the control unit.
Der Resetschalter wird nun erfindungsgemäß so ausgeführt, dass er selbst rückstellend ist. Durch das Ankoppeln einer Kartusche an das Dosiergerät wird der Resetschalter betätigt, so dass er zu dem Reset-Steuersignal führt. Beim Lösen der Kartusche vom Dosiergerät wird der Resetschalter wieder frei gegeben und stellt sich selbst zurück. Dieses Reset-Steuersignal in der Steuereinheit kann man nutzen, um Schaltfunktionen in der oder durch die Steuereinheit zu generieren.The reset switch is now designed according to the invention so that it is itself reset. By coupling a cartridge to the dosing device, the reset switch is actuated so that it leads to the reset control signal. When the cartridge is detached from the dosing device, the reset switch is released again and resets itself. This reset control signal in the control unit can be used to generate switching functions in or by the control unit.
Eine besondere und erfindungsgemäß besonders bevorzugte Schaltfunktion ist die, dass ein Zähler für Dosierzyklen des Dosiergerätes bei Auftreten des Reset-Steuersignals zurückgesetzt wird. Vorzugsweise ist der zurückgesetzte Wert des Zählers gerade der Einstellwert für eine neue Kartusche mit gefüllter Kartuschenkammer. Das handhabungstechnische Ergebnis dieser Gestaltung besteht darin, dass beim Ankoppeln einer Kartusche an das Dosiergerät die Steuereinheit, insbesondere der genannte Zähler, zurückgesetzt wird und klar ist, dass nun eine neue Kartusche im Einsatz ist. Davon ausgehend kann dann die Steuereinheit eigenständig anhand eines Abzählens der Dosierzyklen im weiteren Verlauf der Benutzung des Dosiergerätes z. B. ermitteln, wann die Kartusche leer ist und ausgetauscht werden muss.A special switching function that is particularly preferred according to the invention is that a counter for dosing cycles of the dosing device is reset when the reset control signal occurs. The reset value of the counter is preferably the setting value for a new cartridge with a filled cartridge chamber. The result of this design in terms of handling technology is that when a cartridge is coupled to the metering device, the control unit, in particular the counter mentioned, is reset and it is clear that a new cartridge is now in use. Based on this, the control unit can then independently use a counting of the dosing cycles in the further course of use of the dosing device, for. B. determine when the cartridge is empty and needs to be replaced.
Grundsätzlich kann das Dosiergerät des erfindungsgemäßen Dosiersystems auch so ausgestaltet sein, dass die Steuereinheit einen Kartuschen-Entleerungssensor aufweist oder mit einem solchen verbunden ist. Mit diesem kann dann der Füllzustand einer am Dosiergerät angekoppelten Kartusche überwacht werden. In diesem Fall kann das vom Resetschalter initiierte Reset-Steuersignal beispielsweise dafür genutzt werden, den Kartuschen-Entleerungssensor zu aktivieren.In principle, the metering device of the metering system according to the invention can also be designed in such a way that the control unit has a cartridge emptying sensor or is connected to one. This can then be used to monitor the filling status of a cartridge coupled to the dosing device. In this case, the reset control signal initiated by the reset switch can be used, for example, to activate the cartridge emptying sensor.
Den Resetschalter kann man außerdem für eine weitere Funktion nutzen, nämlich dergestalt, dass die Steuereinheit schaltungstechnisch so eingestellt ist, dass das Reset-Steuersignal gleichzeitig als Einschaltsignal für die Steuereinheit insgesamt oder wesentliche Energie verbrauchende Teile der Steuereinheit dient, so dass bei rückgestelltem Resetschalter die Steuereinheit insgesamt oder die wesentlichen Energie verbrauchenden Teile der Steuereinheit abgeschaltet sind. Ist der Resetschalter hingegen nicht - direkt oder indirekt - in den Versorgungs-Kreis der Steuereinheit oder wesentlicher Energie verbrauchender Teile der Steuereinheit eingeschaltet, so können auch bei rückgestelltem Resetschalter wesentliche Funktionen der elektronischen Steuereinheit ausgeführt werden. Allerdings ist damit dann auch der Energieverbrauch der Steuereinheit höher.The reset switch can also be used for a further function, namely in such a way that the control unit is set in terms of circuitry so that the reset control signal serves simultaneously as a switch-on signal for the control unit as a whole or for parts of the control unit that consume significant energy, so that when the reset switch is reset, the control unit total or the essential energy-consuming parts of the control unit are switched off. If, on the other hand, the reset switch is not switched on - directly or indirectly - in the supply circuit of the control unit or in parts of the control unit that consume significant energy, essential functions of the electronic control unit can also be carried out when the reset switch is reset. However, this also increases the energy consumption of the control unit.
Unter Berücksichtigung der Einsatzumgebung eines Dosiergerätes der in Rede stehenden Art empfiehlt es sich ferner, dass der Resetschalter als elektromechanischer Schalter mit einer federbelasteten mechanischen Schaltwippe o.dgl., einem mit der Schaltwippe o.dgl. beweglichen, elektrischen oder magnetischen Beeinflussungselement und einem davon beeinflussbaren Sensor in oder an der Steuereinheit ausgeführt ist. Nach besonders bevorzugter Lehre ist dabei vorgesehen, dass der Resetschalter als Magnetschalter, insbesondere als Reedschalter, mit einem magnetfeldempfindlichen Sensor in oder an der Steuereinheit und einem dagegen verstellbaren Beeinflussungsmagneten ausgeführt ist. Eine solche elektromechanische bzw. mechanisch/magnetische Konstruktion ist auch im feuchten Umfeld im Inneren beispielsweise einer Geschirrspülmaschine verlässlich zu gestalten.Taking into account the operating environment of a metering device of the type in question, it is also recommended that the reset switch as an electromechanical switch with a spring-loaded mechanical switching rocker or the like, one with the switching rocker or the like. movable, electrical or magnetic influencing element and a sensor that can be influenced in or on the control unit. According to a particularly preferred teaching, it is provided that the reset switch as a magnetic switch, in particular as a reed switch, with a magnetic field-sensitive sensor in or on the control unit and an influencing magnet that is adjustable against it. Such an electromechanical or mechanical / magnetic construction can also be made reliable, for example in the interior of a dishwasher, in a moist environment.
Hinsichtlich der konstruktiven Gestaltung des Dosiergerätes ist in der eingangs erwähnten
Die bisher beschriebene Konstruktion trägt noch nicht der Frage Rechnung, was mit der Steuereinheit des Dosiergerätes geschieht, wenn eine Kartusche zum Teil geleert worden ist, dann vom Dosiergerät gelöst wird und anschließend wieder angekoppelt wird. Um hier eine verwechslungsfreie Konstruktion zu realisieren ist erfindungsgemäß an der Kartusche ein Betätigungselement für einen Resetschalter des Dosiergerätes derart angeordnet und/oder ausgebildet ist, dass das Betätigungselement beim Lösen der Kartusche vom Dosiergerät unwirksam wird, insbesondere abbricht. Beim erstmaligen Ankoppeln einer neuen Kartusche am Dosiergerät wird der Resetschalter also betätigt. Wird die Kartusche gelöst, so wird die Kartusche so verändert, dass bei einem erneuten Ankoppeln der Resetschalter nicht mehr betätigt werden kann. Daraus kann man dann für die Steuereinheit wieder entsprechende Informationen ableiten. Insbesondere kann es so sein, dass die Steuereinheit nicht eingeschaltet wird. Der Benutzer merkt, dass er einen Fehler gemacht hat und tauscht die teilentleerte Kartusche gegen eine neue, funktionsfähige Kartusche aus.The construction described so far does not take into account the question of what happens to the control unit of the metering device when a cartridge has been partially emptied, then detached from the metering device and then coupled again. In order to achieve a mix-up-free construction, according to the invention an actuating element for a reset switch of the metering device is arranged and / or configured on the cartridge such that the actuating element becomes ineffective, in particular breaks off, when the cartridge is released from the metering device. The first time a new cartridge is connected to the dosing device, the reset switch is actuated. If the cartridge is released, the cartridge is changed so that the reset switch can no longer be actuated when the cartridge is connected again. Corresponding information can then be derived from this for the control unit. In particular, the control unit may not be switched on. The user notices that he has made a mistake and replaces the partially empty cartridge with a new, functional cartridge.
Das erfindungsgemäße Dosiersystem ist besonders geeignet zur Verwendung in Wasser führenden Haushaltsgeräten wie Geschirrspülmaschinen oder auch Waschmaschinen. Der Einsatz ist jedoch nicht auf eine derartige Verwendung beschränkt.The dosing system according to the invention is particularly suitable for use in water-bearing household appliances such as dishwashers or washing machines. However, use is not limited to such use.

Diese Kartusche 11 ist hier also noch vom Dosiergerät 5 gelöst dargestellt. Die Kartusche 11 hat mindestens eine Kartuschenkammer 12.

In
Mit dem erfindungsgemäß vorhandenen Resetschalter 18 wird erfindungsgemäß in der Steuereinheit 8 ein Reset-Steuersignal generiert, das die Information liefert, ob eine Kartusche 11 am Dosiergerät 5 angekoppelt ist oder nicht. Diese Information kann man in der Steuereinheit 8 auf verschiedene Weise nutzen.With the
Eine erste und besonders wesentliche Form, das Reset-Steuersignal zu nutzen besteht darin, dass die Steuereinheit 8 einen Zähler für Dosierzyklen des Dosiergerätes 5 aufweist und der Zähler bei Auftreten des Reset-Steuersignals zurückgesetzt wird, wobei der zurückgesetzte Wert des Zählers vorzugsweise dem Einstellwert für eine neue Kartusche 11 mit gefüllter Kartuschenkammer 12 entspricht.A first and particularly essential form of using the reset control signal is that the
Der Begriff "Zähler" bedeutet in diesem Zusammenhang jede Art elektronischer oder programmierter Einrichtung, deren Messwert sich in Abhängigkeit von der Anzahl abgelaufener Dosierzyklen verändert oder verändern lässt. Insbesondere ist das eben ein Zähler im engeren Sinne.The term "counter" in this context means any type of electronic or programmed device, the measured value of which can be changed or changed depending on the number of metering cycles that have elapsed. In particular, this is just a counter in the narrower sense.
Das Reset-Steuersignal, das beim Ansetzen einer neuen Kartusche 11 an das Dosiergerät 5 generiert wird, führt also bei dieser Ausführungsform dazu, dass der zurückgesetzte Wert des Zählers der Einstellwert für eine neue Kartusche 11 mit vollständig gefüllter Kartuschenkammer 12 ist. Das Dosiergerät 5 bzw. dessen Steuereinheit 8 hat so die Information, dass von einer gefüllten Kartusche 11 ausgegangen werden kann und die volle Anzahl zu erwartender Dosierzyklen abgearbeitet werden kann. Damit kann die Steuereinheit 8 durch Benutzung des Zählers eigenständig ermitteln, ob die angekoppelte Kartusche 11 noch voll, bereits teilweise entleert oder so gut wie vollständig entleert ist und ausgewechselt werden muss. Entsprechend kann von der Steuereinheit 8 ein Signal abgegeben werden, insbesondere über die Anzeige- oder Bedienelemente 9 am Gehäuse 6 des Dosiergerätes 5.In this embodiment, the reset control signal that is generated when a
Ist eine Kartusche 11 nicht am Dosiergerät 5 angekoppelt, so ist das Dosiergerät 5 an sich funktionsunfähig. Deshalb kann man vorsehen, dass das Dosiergerät 5 und dessen Steuereinheit 8 überhaupt nur betriebsfähig ist, wenn eine Kartusche 11 angekoppelt ist. Hier kann der Resetschalter 18 eine weitere Funktion übernehmen, nämlich dergestalt, dass die Steuereinheit 8 schaltungstechnisch so eingestellt ist, dass das Reset-Steuersignal gleichzeitig als Einschaltsignal für die Steuereinheit 8 insgesamt oder wesentliche Energie verbrauchende Teile der Steuereinheit 8 dient, so dass bei rückgestelltem Resetschalter 18 die Steuereinheit 8 insgesamt oder die wesentlichen Energie verbrauchenden Teile der Steuereinheit 8 abgeschaltet sind.If a
Insbesondere kann man in diesem Zusammenhang vorsehen, dass die wesentlichen Energie verbrauchenden Teile der Steuereinheit 8 abgeschaltet sind, wenn der Resetschalter 18 rückgestellt ist. Einige wesentliche, auch bei fehlender Kartusche 11 erforderliche Funktionen der Steuereinheit 8 können dabei erhalten bleiben, insbesondere auch die Funktion des Einschaltens der Steuereinheit 8 bei Betätigen des Resetschalters 18.In particular, it can be provided in this connection that the essential energy-consuming parts of the
Zuvor ist ausgeführt worden, dass die Steuereinheit 8 erfindungsgemäß einen Resetschalter 18 aufweist oder mit diesem verbunden ist. Der Resetschalter kann also zunächst einmal vollständiger Bestandteil der Steuereinheit 8 sein. Das kann man beispielsweise mit einem elektronischen, kapazitiven oder induktiven Näherungsschalter realisieren. Solche Konstruktionen sind aber im Umfeld einer Geschirrspülmaschine mit der sehr feuchten Umgebungsatmosphäre nicht optimal.It was previously stated that the
Demzufolge weist nach bevorzugter Lehre der Erfindung das Dosiergerät 5 einen mit der Steuereinheit 8 verbundenen Resetschalter 18 auf, der als elektromechanischer Schalter ausgeführt ist. Im Einzelnen ist vorgesehen, dass nach bevorzugter Lehre der Resetschalter 18 eine federbelastete mechanische Schaltwippe 19 oder ein anderes, ähnliches mechanisches Betätigungselement aufweist. Diese Schaltwippe 19 oder dgl. ist im Gehäuse 6 des Dosiergerätes 5 an passender Stelle angeordnet. Mit der Schaltwippe 19 beweglich ist ein elektrisches oder magnetisches Beeinflussungselement 20. Innerhalb der Steuereinheit 8 und geschützt vor Feuchtigkeit befindet sich ein vom elektrischen oder magnetischen Beeinflussungselement 20 körperlich getrennter, jedoch beeinflussbarer Sensor 21.Accordingly, according to the preferred teaching of the invention, the
Ganz konkret kann man das so ausgestalten, dass der Resetschalter 18 als Magnetschalter, insbesondere als Reedschalter, ausgeführt ist. Der Sensor 21 ist dabei ein magnetfeldempfindlicher Sensor, der bevorzugt in der Steuereinheit 8 feuchtigkeitsgeschützt angeordnet ist. Insbesondere empfiehlt sich hier ein Hallsensor. Dagegen verstellbar ist ein Beeinflussungsmagnet, der hier das Beeinflussungselement 20 des Resetschalters 18 darstellt.In concrete terms, this can be designed in such a way that the

Im hier dargestellten und bevorzugten Ausführungsbeispiel setzt sich also der Resetschalter 18 aus einer mechanischen Komponente, nämlich der Schaltwippe 19 mit ihren Bestandteilen, einer magnetischen Komponente, nämlich dem Beeinflussungsmagneten 20, und einer elektronischen Komponente, nämlich dem Hallsensor 21 zusammen.In the exemplary embodiment shown and preferred here, the

Beim dargestellten Ausführungsbeispiel ist nun vorgesehen, dass der Resetschalter 18 an dem Ende des Gehäuses 6 angeordnet ist, das dem die Schwenkverbindung bildenden Ende gegenüberliegt. Der Resetschalter 18 wird also erst ganz am Schluss, bei vollständig eingerasteter Kartusche 11 betätigt. So kann man Fehlbetätigungen des Resetschalters 18 vermeiden.In the exemplary embodiment shown, it is now provided that the
An sich liegt es auf der Hand, dass die Kartusche 11, wenn sie einmal am Dosiergerät 5 angekoppelt war, zu Ende verwendet werden muss. Löst man nämlich die Kartusche 11 vom Dosiergerät 5, so bleiben die Auslassöffnungen 13 der Kartuschenkammern 12 offen. Das in den Kartuschenkammern 12 befindliche Wasch- oder Reinigungsmittel kann dann mehr oder weniger ungehindert aus den Kartuschenkammern 12 heraustropfen. Eine solche Kartusche 11 kann man an sich nur entsorgen.It is obvious that the
Um Fehlbedienungen zu vermeiden kann man aber vorsehen, dass die Kartusche 11, ist sie denn erst einmal benutzt worden, nicht ein weiteres Mal am Dosiergerät 5 angesetzt werden kann. Zumindest kann verhindert werden, dass das Dosiergerät 5 mittels des Resetschalters 18 dann wieder aktiviert wird. Dazu ist nach bevorzugter, jedoch nicht dargestellter Lehre der Erfindung vorgesehen, dass an der Kartusche 11 ein Betätigungselement für einen Resetschalter 18 des Dosiergerätes 5 derart angeordnet und/oder ausgebildet ist, dass das Betätigungselement beim Lösen der Kartusche 11 vom Dosiergerät 5 unwirksam wird, insbesondere abbricht.In order to avoid incorrect operation, it can be provided that the
Nimmt man die Kartusche 11 vom Gehäuse 6 des Dosiergerätes 5 ab, so ist dann das Betätigungselement für den Resetschalter 18 unbrauchbar. Ein erneutes Ankoppeln der Kartusche 11 an das Gehäuse 6 hat hinsichtlich der Steuereinheit 8 keine Wirkung mehr. Insbesondere dann, wenn der Resetschalter 18 auch auf die Einschaltung der Steuereinheit 8 insgesamt einen Einfluss hat, ist das eine sehr wirkungsvolle Schutzmaßnahme.If the
