Description
Die Erfindung betrifft ein Verfahren zur Salzmangelerkennung bei einer mit einem Enthärter ausgestatteten Geschirrspülmaschine oder Waschmaschine, wobei ein Salzbehälter des Enthärters zur Soleaufbereitung an Frischwasser oder dergl. angeschlossen und ein Ionenaustauscher mit der Salzsole aus dem Salzbehälter regeneriert wird, und wobei zur Sensierung eines Salzmangels die Dichte der Salzsole herangezogen wird. Ferner betrifft die Erfindung eine entsprechende Einrichtung zur Durchführung des Verfahrens.The invention relates to a method for salt deficiency detection in a softener equipped dishwasher or washing machine, using a salt container of the softener connected to fresh water or the like for brine treatment and an ion exchanger is regenerated with the brine from the salt container, and being used to sense a In the absence of salt, the density of the brine is used. The invention further relates to a corresponding one Facility for carrying out the procedure.
Aus der DE-A 2 354 662 ist ein aus Salzbehälter und lonenaustauscher bestehender regenerierbarer Enthärter für eine Geschirrspülmaschine oder Waschmaschine bekannt, bei welchem zur Anzeige einer genügenden Solekonzentration im Salzbehälter in einem vertikalen Raum ein Schwimmer untergebracht ist, dessen Gewicht oder Hohlvolumen so bemessen ist, dass dieser bei einem Konzentrationswert oder Dichte der Salzsole oberhalb eines kritischen Wertes aufschwimmt und andererseits absinkt, wenn die Dichte der Sole unterhalb des kritischen Wertes liegt. Ist dies der Fall, so muss Regeneriersalz nachgefüllt werden. Zur Anzeige dieser Situation beinhaltet der Schwimmer einen Permanentmagneten, welcher einen außerhalb des Salzbehälters angebrachten Reedkontakt schaltet, der für den Benutzer des Gerätes das entsprechende Signal zum Salznachfüllen abgibt. Die Meldung zum Salznachfüllen erfolgt somit erst dann, wenn die kritische Dichte bereits unterschritten, also der lonenaustauscher schon nahezu erschöpft ist. Dies kann ggf. zu einem verschlechterten Spülergebnis mit Kalkablagerungen insbesondere bei empfindlichen Gläsern führen. Darüber hinaus besteht die Gefahr, dass sich der Schwimmer durch nachgefülltes Regeneriersalz verklemmt, oder dass dieser undicht wird und die Auftriebsverhältnisse für eine sichere Anzeige nicht mehr gegeben sind. Auch hier soll die Erfindung Abhilfe schaffen.DE-A 2 354 662 describes a regenerable system consisting of a salt container and an ion exchanger Softener known for a dishwasher or washing machine, in which to indicate a sufficient brine concentration in the salt container in a vertical room Float is housed, whose weight or hollow volume is dimensioned so that this at a concentration value or density of the brine above a critical value and on the other hand decreases when the density of the brine is below the critical value lies.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Salzmangelsensierung mit hoher Zuverlässigkeit, Genauigkeit und niedrigen Kosten zu schaffen.The invention is therefore based on the object of detecting a lack of salt with high reliability, To create accuracy and low cost.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren gemäß den Merkmalen des Patentanspruchs
1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben
sich aus den nachfolgenden Unteransprüchen. Die Einrichtung zur Durchführung des Verfahrens
ist durch die Merkmale des Anspruchs 3 gekennzeichnet, wobei den nachfolgenden abhängigen
Unteransprüchen vorteilhafte Weiterentwicklungen der erfindungsgemäßen Einrichtung
zur Salzmangelsensierung zu entnehmen sind.According to the invention, this object is achieved by a method according to the features of the
Durch die vorteilhafte Ausnutzung des jeweiligen Dichteunterschieds zwischen dem zugeführten Frischwasser und der Salzsole und der daraus erfindungsgemäß umgesetzten Flüssigkeitshöhendifferenzen von Sole und Frischwasser in entsprechende Flüssigkeitssäulen kann einfach und zuverlässig mit wenig Bauaufwand und niedrigen Kosten sehr genau die jeweilige Solekonzentration sensiert werden. Dies ist durch einen einfachen Lichtsensor in Art einer optischen Lichtschranke oder auch durch einen einfachen Schwimmkörper realisierbar, welcher auf der Flüssigkeitssäule unbeeinflusst von der Solekonzentration im Frischwasser schwimmt. Eine Verschmutzung des Sensors bzw. der Reflexionsflächen des optischen Sensors ist nicht zu erwarten, weil der Leitungsweg mit dem Sensor mit jedem Regeneriervorgang des Ionenaustauschers im Spülbetrieb des wasserführenden Gerätes mit Frischwasser durchflutet wird.Through the advantageous use of the respective density difference between the supplied Fresh water and the brine and the resulting liquid height differences according to the invention of brine and fresh water in appropriate liquid columns simple and reliable with little construction effort and low costs very precisely the respective one Brine concentration to be sensed. This is due to a simple light sensor in the manner of an optical one Photoelectric barrier or also realizable by a simple floating body, which on the liquid column floats unaffected by the brine concentration in the fresh water. A Contamination of the sensor or the reflection surfaces of the optical sensor is not to be avoided expect because the conduction path with the sensor with every regeneration process of the ion exchanger is flooded with fresh water in the flushing mode of the water-carrying device.

Ein regenerierbarer Enthärter (1) einer nicht dargestellten an ein Frischwassernetz angeschlossenen Geschirrspülmaschine oder Waschmaschine für zum Geschirrspülen oder Waschen bereitzustellendes weiches Wasser weist einen Salzbehälter (2) mit einem Frischwasseranschluss (3) zur Aufbereitung von Salzsole (8) zum Regenerieren eines nachgeschalteten lonenaustauschers (4) der Einrichtung auf.A regenerable softener (1) connected to a fresh water network, not shown Dishwasher or washing machine for dishwashing or washing Soft water to be provided has a salt container (2) with a fresh water connection (3) for the treatment of brine (8) for the regeneration of a downstream ion exchanger (4) the facility.
Der Salzbehälter (2) kann beispielsweise innerhalb der Gerätetür der Geschirrspülmaschine installiert sein, und weist oberseitig eine Einfüllöffnung (5) zum Nachfüllen von Regeneriersalz (6) für den eingebauten Salzbehälter (2) des geräteeigenen Enthärters (1) auf. Bei in der Gerätetür angeordnetem Salzbehälter (2) ist die Einfüllöffnung (5) türinnenseitig in einer bedienerfreundlichen Türhöhe angebracht.The salt container (2) can, for example, inside the appliance door of the dishwasher be installed, and has a filling opening (5) on the top for refilling regeneration salt (6) for the built-in salt container (2) of the device's own softener (1). At in the Salt container (2) arranged on the appliance door, the filling opening (5) on the inside of the door is user-friendly Door height attached.
Im Innern des Salzbehälters (2), siehe auch Fig. 2, ist eine Kammer (7) oberhalb eines Salzsiebes (20) vorgesehen, welche das in den Behälter eingefüllte Regeneriersalz (6) sowie die über dem Salz im Behälterraum befindliche Salzsole (8) aufnimmt. Der Behälterraum mit dem gelösten Regeneriersalz (Salzsole 8) ist durch einen Soleüberlauf (9) begrenzt, von welchem eine auch vorzugsweise ventilgesteuerte Soleleitung (10) zum lonenaustauscher (4) führt, der seinerseits in den Spülbehälter (11) der nicht gezeigten Wasch- oder Geschirrspülmaschine ausmündet. Zur Weichwasseraufbereitung ist der lonenaustauscher (4) in an sich bekannter Weise ebenfalls mit einem Anschluss (12) für Frischwasser (F) versehen. Inside the salt container (2), see also Fig. 2, is a chamber (7) above a salt sieve (20) provided, which the filled in the container of regeneration salt (6) and the the salt brine (8) located in the container space. The container room with the solved Regeneration salt (brine 8) is limited by a brine overflow (9), one of which also preferably valve-controlled brine line (10) leads to the ion exchanger (4), which in turn leads opens into the washing container (11) of the washing machine or dishwasher, not shown. For soft water treatment, the ion exchanger (4) is in a manner known per se also provided with a connection (12) for fresh water (F).
Für die Soleaufbereitung wird das in einem niveaumäßig oberhalb des Salzbehälters (2) angeordneten Vorratsbehälter (13) bevorratete Frischwasser (F) benutzt, das nicht enthärtet ist. Der vom Vorratsbehälter (13) zum Salzbehälter (2) geführte Frischwasserzulauf (14) ist ventilgesteuert (Magnetventil 15). Am Ende eines Spülprogramms erfolgt automatisch das Regenerieren des lonenaustauschers (4), wobei sichergestellt sein muss, dass hierfür eine Solemenge mit ausreichender Solekonzentrationen oder Dichte zur Verfügung steht.For the brine preparation, this is arranged in a level above the salt container (2) Reservoir (13) used fresh water (F) is used, which is not softened. The The fresh water inlet (14) from the storage container (13) to the salt container (2) is valve-controlled (Solenoid valve 15). Regeneration takes place automatically at the end of a washing program of the ion exchanger (4), whereby it must be ensured that a brine quantity is required for this with sufficient brine concentrations or density is available.
Zum Regenerierzeitpunkt wird das im Frischwasserzulauf (14) angeordnete Magnetventil (15) solange geöffnet, bis eine bemessene Frischwassermenge aus dem Vorratsbehälter (13) in den Salzbehälter (2) abgeführt ist. Dabei wird eine entsprechende Solemenge aus dem Salzbehälter (2) verdrängt und über den Soleüberlauf (9) in den lonenaustauscher (4) geleitet. Herrscht ein Salzmangel vor, der aufgrund der damit verbundenen Verringerung der Soledichte ein unzureichendes Regenerieren des Enthärters (1) veranlassen würde, so ist dieser Zustand dem Gerätebediener frühzeitig anzuzeigen. Hierfür ist die Einrichtung mit einer Salzmangelanzeige (16) ausgebildet.At the time of regeneration, the solenoid valve (15) arranged in the fresh water inlet (14) is open until a measured amount of fresh water from the reservoir (13) in the salt container (2) is removed. A corresponding amount of brine from the salt container (2) displaced and passed through the brine overflow (9) into the ion exchanger (4). There is a lack of salt due to the associated reduction in brine density this would result in inadequate regeneration of the softener (1) to notify the device operator in good time. This is the facility with a salt deficiency indicator (16) trained.
Zur Sensierung eines Salzmangels wird nach der Erfindung die Dichte der Salzsole sowie die Dichte des dem Salzbehälter (2) zur Aufbereitung der Salzsole zugeführten Frischwassers aus dem Vorratsbehälter herangezogen. Aus den unterschiedlichen Flüssigkeitsdichten werden erfindungsgemäß unterschiedlich hohe Flüssigkeitssäulen (SSO; SF) von Salzsole und Frischwasser erzeugt. Die jeweilige Höhendifferenz (H) der beiden Flüssigkeitssäulen (SSO; SF) wird als Maß für die Solekonzentration gewertet und angezeigt.According to the invention, the density of the salt brine and the density of the fresh water supplied to the salt container (2) for the treatment of the salt brine from the storage container are used to sense a lack of salt. According to the invention, different liquid columns (S SO ; S F ) of brine and fresh water are produced from the different liquid densities. The respective height difference (H) of the two liquid columns (S SO ; S F ) is evaluated and displayed as a measure of the brine concentration.
Die Einrichtung zur Durchführung des Verfahrens ist dazu wie folgt aufgebaut:The device for carrying out the method is structured as follows:
Vom Salzbehälter (2) zweigt unterhalb des Salzsiebes (20) aus der Salzsole (8) ein nach Art einer kommunizierenden Röhre ausgebildeter nach oben hin offener (Luft oder Umgebungsdruck) Leitungsweg (17) mit einem Überlauf (18) ab. Dieser Leitungsweg (17) wird vom Frischwasser (F) über den Frischwasseranschluss (3) des Salzbehälters (2) gespeist. Der für das Frischwasser vorgesehene Überlauf (18) im Leitungsweg (17) ist vorzugsweise unterhalb der Schwelle des im Salzbehälter (2) liegenden Soleüberlaufs (9) zum lonenaustauscher (4) angeordnet (siehe Fig. 2), wobei der Soleüberlauf (9) ortsfest und dementsprechend konstant ist. Im Leitungsweg (17) mit dem Überlauf (18) ist die Flüssigkeitssäule (SF) für das Frischwasser ausgebildet, deren Niveau je nach Dichte der kommunizierenden Sole-Flüssigkeitssäule (SSO) des Salzbehälters (2) mehr oder weniger über dem Überlauf (18) für das Frischwasser bei gesperrtem Magnetventil (15) pendelt. Die Messung eines Salzmangels erfolgt bei geschlossenem Magnetventil (15).A line path (17) with an overflow (18), which is open at the top (air or ambient pressure) and is designed in the manner of a communicating tube, branches off from the salt container (2) below the salt sieve (20) from the salt brine (8). This line path (17) is fed by the fresh water (F) via the fresh water connection (3) of the salt container (2). The overflow (18) provided for the fresh water in the conduit (17) is preferably arranged below the threshold of the brine overflow (9) in the salt container (2) to the ion exchanger (4) (see FIG. 2), the brine overflow (9) being stationary and is accordingly constant. The liquid column (S F ) for the fresh water is formed in the line path (17) with the overflow (18), the level of which, depending on the density of the communicating brine liquid column (S SO ) of the salt container (2), is more or less above the overflow (18 ) for the fresh water with the solenoid valve (15) locked. A lack of salt is measured with the solenoid valve (15) closed.
Der vorerwähnte Leitungsweg (17) ist außerhalb des Salzbehälters (2) verlegt, vorzugsweise an diesen angeformt, wobei die Salzmangelanzeige (16) zur Sensierung der Flüssigkeitshöhendifferenz (H) im Leitungsweg (17) oberhalb des Überlaufs (18) vorgesehen und vorzugsweise durch einen optischen Sensor (19) in Art einer Reflexionslichtschranke realisiert. Die Anzeige kann aber auch durch einen im Leitungsweg (17) in der Flüssigkeitssäule (SF) des Frischwassers angeordneten Schwimmer realisiert werden, wobei der Schwimmer auf der Frischwasser-Flüssigkeitssäule (SF) schwimmt.The above-mentioned line path (17) is laid outside the salt container (2), preferably molded onto it, the salt deficiency indicator (16) being provided for sensing the liquid level difference (H) in the line path (17) above the overflow (18) and preferably by an optical one Sensor (19) implemented in the manner of a reflection light barrier. However, the display can also be implemented by a float arranged in the conduit path (17) in the liquid column (S F ) of the fresh water, the float floating on the fresh water liquid column (S F ).
Die auf dem System kommunizierender Röhren basierende Salzmangelerkennung arbeitet einfach und zuverlässig. Eine Verschmutzung des Sensors (19) bzw. der Reflexionsflächen des optischen Sensors (19) ist nicht zu erwarten, weil der Leitungsweg (17) mit dem Sensor (19) mit jedem Regeneriervorgang des Ionenaustauschers (4) im Spülbetrieb des wasserführenden Gerätes mit Frischwasser durchflutet wird. Durch den labyrinthartig am Salzbehälter (2) hochgeführten Leitungsweg (17) wird verhindert, dass sich das Frischwasser im Leitungsweg (17) bzw. im Frischwasseranschluss (3) mit Salzsole (8) aus dem Salzbehälter (2) vermischt. Im Falle eines Einbaus des Salzbehälters (2) in der Gerätetür einer Geschirrspül- oder Waschmaschine treten somit auch beim mehrfachen Türöffnen und -schließen keine Flüssigkeitsvermischungen auf, welche die Anzeige ungenau arbeiten lassen. Aufgrund des Dichteunterschiedes steht die Frischwassersäule (SF) im Leitungsweg (Labyrinth) höher als die vom Soleüberlauf bestimmte Salzsolesäule (SSO). Diese Höhendifferenz wird sensiert und ist ein Maß für die Solekonzentration.The salt deficiency detection based on the system of communicating tubes works simply and reliably. Contamination of the sensor (19) or the reflection surfaces of the optical sensor (19) is not to be expected because the line path (17) with the sensor (19) is flooded with fresh water with each regeneration process of the ion exchanger (4) in the flushing operation of the water-carrying device becomes. The labyrinthine line path (17) leads up to prevent that the fresh water in the line path (17) or in the fresh water connection (3) is mixed with brine (8) from the salt container (2). In the event that the salt container (2) is installed in the door of a dishwasher or washing machine, there are no liquid mixtures, even if the door is opened and closed several times, which would make the display work inaccurately. Due to the difference in density, the fresh water column (S F ) in the pipeline (labyrinth) is higher than the brine overflow determined by the brine overflow (S SO ). This height difference is sensed and is a measure of the brine concentration.
Gemäß dem gezeigten Ausführungsbeispiel wird der Solespiegel konstant gehalten. Nimmt die Solekonzentration ab, sinkt der Frischwasserspiegel. Um den Salzmangel zu sensieren, ist in der bestimmten Mindesthöhe (über dem Überlauf) der Sensor (19) der Salzmangelanzeige (16) installiert. Andererseits könnte der Frischwasserspiegel aber auch konstant gehalten werden, damit der Solespiegel in Abhängigkeit von der Solekonzentration auswertbar pendeln kann. Erstere Anordnung mit dem ortsfesten Soleüberlauf (9) ist jedoch am einfachsten zu realisieren.According to the exemplary embodiment shown, the brine level is kept constant. Take that Brine concentration drops, the fresh water level drops. To sense the lack of salt, is in the determined minimum height (above the overflow) of the sensor (19) of the low salt indicator (16) Installed. On the other hand, the fresh water level could also be kept constant, so that the brine level can oscillate depending on the brine concentration. The first arrangement with the stationary brine overflow (9) is, however, the easiest to implement.
