Description

Die Erfindung betrifft eine Haushalt-Geschirrspülmaschine nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a household dishwasher according to the preamble of the first claim.

Bei einer bekannten Haushalt-Geschirrspülmaschine dieser Art (DE-GM 87 03 731) mit Wasserenthärtungsvorrichtung, bestehend aus Salzvorratsbehälter und lonenaustauscher, Regenerierwasser-Speicherbehälter und Wärmeaustauscher ist ein wärmeleitend mit dem Spülbehälter verbundener Vorratsbehälter, der Ionenaustauscher, der Salzvorratsbehälter, der Speicherbehälter, eine freie Fließstrecke und ein Niveaugeber in einem Wassereinlaufbehälter zusammengefaßt, wobei der Wassereinlaufbehälter eine mit dem Salzvorratsbehälter strömungsverbundene Röhre aufweist, in der ein Schwimmer zur Salzmangelanzeige vorgesehen ist.In a known household dishwasher of this type (DE-GM 87 03 731) with a water softening device, consisting of a salt storage container and ion exchanger, regeneration water storage container and heat exchanger, a storage container connected in a heat-conducting manner, the ion exchanger, the salt storage container, the storage container, is a free one The flow path and a level transmitter are combined in a water inlet container, the water inlet container having a tube which is in flow connection with the salt reservoir and in which a float is provided to indicate the lack of salt.

Bei einer weiteren Haushalt-Geschirrspülmaschine dieser Art (DE-P 38 05 084.6) ist eine mittels eines Deckels verschließbare Enfüllöffnung des Salzvorratsbehälters durch eine Spülbehälter-Seitenwand geführt und vom Spülraum des Spülbehälters aus zugänglich, wobei die Einfüllöffnung in einem in die Spülbehälter-Seitenwand eingesetzten Rahmen angeordnet ist und der Deckel abschwenkbar im Bereich des unteren Einfüllrandes des Rahmens gelagert ist. Eine das Regeneriermittel für den Salzvorratsbehälter aufnehmende Schütte ist in den Deckel einsetzbar und wird bei geschlossenem Deckel in diesem in Dosierlage gehalten.In another household dishwasher of this type (DE-P 38 05 084.6), a filler opening of the salt storage container, which can be closed by a lid, is guided through a side wall of the washing container and is accessible from the washing compartment of the washing container, the filling opening being inserted into a side wall of the washing container Frame is arranged and the lid is pivotally mounted in the region of the lower filling edge of the frame. A chute receiving the regenerating agent for the salt storage container can be inserted into the lid and is held in the metering position in the lid when the lid is closed.

Bei bekannten Haushalt-Geschirrspülmaschinen der eingangs erwähnten Art wird nach dem Einfüllen des Salzes durch den Benutzer die Salzmangelanzeige nicht sofort gelöscht, da zur Lösung des Salzes und damit zur Anzeige des Füllzustandes des Salzvorratsbehälters eine längere Zeit benötigt wird. Diese Fehlanzeige führt zum weiteren unnötigen Nachfüllen von Salz durch den Benutzer. Durch das Mehreinfüllen von Salz kommt es zu einem Überlaufen des Salzvorratsbehälters und die übergelaufene Sole wird über den Spülbehälter der Haushalt-Geschirrspülmaschine in den Abfluß geleitet, was zu einer unnötigen Salzbelastung des Abwassers führt. Außerdem treten natürlich Mehrkosten für den Benutzer durch unnötig eingefülltes Salz auf. Bei Haushalt-Geschirrspülmaschinen dieser Art kann bei der Fertigung eine Funktionskontrolle der Salzmangelanzeige nicht erfolgen. Weiterhin werden Haushalt-Geschirrspülmaschinen in Gebieten eingesetzt, in denen die Wasserhärte so niedrig ist, daß der Betrieb der Wasserenthärtungsvorrichtungen nicht notwendig wird und vom Benutzer kein Salz eingefüllt werden soll. Bei Haushalt-Geschirrspülmaschinen der eingangs erwähnten Art zeigt die Salzmangelanzeige dann aber ständig einen Salzmangel an, was zu Täuschungen des Benutzers führt.In known household dishwashers of the type mentioned at the outset, the salt deficiency indicator is not deleted immediately after the salt has been filled in by the user, since a longer time is required to dissolve the salt and thus to display the filling status of the salt storage container. This incorrect display leads to further unnecessary refilling of salt by the user. The additional filling of salt leads to an overflow of the salt storage container and the overflowed brine is led into the drain via the washing container of the household dishwasher, which leads to an unnecessary salt load in the waste water. In addition, there are of course additional costs for the user due to unnecessarily filled salt. In household dishwashers of this type, the salt deficiency indicator cannot be functionally checked during manufacture. Household dishwashers are also used in areas where the water hardness is so low that the operation of the water softening devices is not necessary and the user should not fill in salt. In household dishwashers of the type mentioned at the outset, however, the salt deficiency indicator then constantly indicates a salt deficiency, which leads to the user being deceived.

Der Erfindung liegt die Aufgabe zugrunde, eine Haushalt-Geschirrspülmaschine der eingangs genannten Art so zu gestalten, daß eine Falschanzeige in den vorgenannten Fällen vermieden und eine Fertigungskontrolle möglich wird.The invention has for its object to design a household dishwasher of the type mentioned so that a false display in the aforementioned cases is avoided and a production control is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Stellmittel angeordnet sind, über die der Schwimmer vom Benutzer in eine zumindest Salzsolevorrat anzeigende Stellung verstellbar ist und in dieser Stellung freigegeben wird. Bevorzugte Ausführungsarten sind im folgenden dargelegt.This object is achieved in that adjusting means are arranged, via which the float can be adjusted by the user into a position indicating at least brine and is released in this position. Preferred embodiments are set out below.

Nach einem bevorzugten Merkmal der Erfindung bewegt der Deckel die Stellmittel beim Öffnen oder Schließen und gibt die Stellmittel beim Schließen frei.According to a preferred feature of the invention, the cover moves the adjusting means when opening or closing and releases the adjusting means when closing.

Nach einem weiteren Merkmal der Erfindung bleibt der Schwimmer in der zumindest Salzsolevorrat anzeigenden Stellung festgelegt, bis das in den Salzvorratsbehälter eingefüllte Salz zum größten Teil aufgelöst ist.According to a further feature of the invention, the float remains in the position indicating at least salt brine until the salt poured into the salt reservoir is largely dissolved.

Zweckmäßigerweise wird der Schwimmer durch das eingefüllte Salz in der zumindest Salzsolevorrat anzeigenden Stellung festgelegt.The float is expediently fixed by the filled salt in the position indicating at least the salt brine.

Bei einer von dem Schwimmer ausgelösten Salzmangelanzeige wird also vom Benutzer durch das zur Behebung des angezeigten Salzmangels notwendig gewordenen Nachfüllen von Salz, das bei den eingangs erwähnten Haushalts-Geschirrspülmaschinen durch das Einschütten von Salz in die Einfüllöffnung des Salzvorratsbehälters und das dabei zwangsläufig notwendig gewordenen Öffnen und Schließen des diese Einfüllöffnung verschließenden Deckels geschieht über durch den Deckel bewegte Stellmittel der Schwimmer in eine zumindest Salzsolevorrat anzeigende Stellung gebracht und zweckmäßigerweise von dem eingefüllten Salz selbst in dieser Stellung gehalten, bis das Salz zum größten Teil aufgelöst ist.In the event of a salt deficiency indicator triggered by the float, the user is therefore required to refill the salt that has become necessary to remedy the salt deficiency indicated, in the case of the household dishwashers mentioned at the beginning by pouring salt into the filling opening of the salt storage container and the opening and opening that has become necessary Closing the lid closing this filling opening takes place by means of actuating means moved by the lid, the float is brought into a position indicating at least brine and is advantageously held in this position by the filled salt until the salt is largely dissolved.

Nach einem bevorzugten Merkmal der Erfindung sind die Stellmittel zur zwangsweisen Bewegung des Schwimmers ein Durchbruch des Schwimmers, der Deckel und eine im Bereich der Einfüllöffnung angeordnete Wippe, wobei die Wippe durch das Schließen des Deckels zwangweise bewegt wird.According to a preferred feature of the invention, the actuating means for the forced movement of the float are an opening in the float, the lid and a rocker arranged in the area of the filler opening, the rocker being forcibly moved by closing the lid.

Vorteilhafterweise ist die Wippe an dem Rahmen der Einfüllöffnung drehbar gelagert und mit einem in den Bereich des Deckels ragenden Schalthebel und mit einem in den Durchbruch des Schwimmers ragenden Auslösehebel ausgestattet.Advantageously, the rocker is rotatably mounted on the frame of the filling opening and is equipped with a switching lever protruding into the area of the cover and with a release lever protruding into the opening of the float.

Zweckmäßigerweise ist der Deckel mit einem im Bereich der Wippe vorstehenden einstückig angeformten Schaltbügel ausgestattet.The cover is expediently equipped with a switching bracket formed in one piece in the region of the rocker.

Vorteilhafterweise beaufschlagt der Schaltbügel während der Schließbewegung des Deckels über die Wippe den Schwimmer anhebend.Advantageously, the switching bracket acts on the float during the closing movement of the cover via the rocker.

Erfindungsgemäß gibt der Schaltbügel bei vollständig geschlossenem Deckel die Wippe wieder frei.According to the invention, the switching bracket releases the rocker when the cover is completely closed.

Bei dieser bevorzugten Ausführungsform der Erfindung wird also durch das Schließen des Deckels die mit ihrem Auslösehebel in den Durchbruch des Schwimmers ragende Wippe so gedreht, daß der Schwimmer angehoben wird und bei vollständig geschlossenem Deckel wird die Wippe wieder freigegeben.In this preferred embodiment of the invention, the rocker which projects with its release lever into the opening of the float is rotated by closing the lid in such a way that the float is raised and when the lid is completely closed, the rocker is released again.

Nach einer vorteilhaften Ausführungsform der Erfindung wird der Schwimmer mit Stellmitteln dauernd in einer zumindest Salzsolevorrat anzeigenden Stellung festgelegt.According to an advantageous embodiment of the invention, the float is permanently fixed with adjusting means in a position indicating at least brine.

Zweckmäßigerweise sind die Stellmittel zur dauernden Festlegung des Schwimmers der Durchbruch des Schwimmers, die Wippe und eine am Rahmen der Einfüllöffnung angeordnete Rastnocke, wobei die Wippe mittels der Rastnocke dauernd festgelegt wird.Expediently, the actuating means for permanently fixing the float are the breakthrough of the float, the rocker and a locking cam arranged on the frame of the filler opening, the rocker being permanently fixed by means of the locking cam.

Mit diesen Maßnahmen ist es für den Einsatz von Haushalt-Geschirrspülmaschinen in Gebieten, in denen die Wasserhärte so niedrig ist, daß der Betrieb der Wasserenthärtungsvorrichtung der Haushalt-Geschirrspülmaschine nicht notwendig ist, möglich, für den Benutzer irreführende Salzmangelanzeigen zu vermeiden.With these measures it is possible for the use of household dishwashers in areas where the water hardness is so low that the operation of the water softening device of the household dishwashing machine is not necessary to avoid misleading salt deficiency indicators for the user.

Nach einem weiteren Merkmal der Erfindung wirkt der Schwimmer auf eine Anzeigevorrichtung, die ein optisches oder akustisches Signal abgibt, ein. Alternativ kann die Anzeigevorrichtung an einer Bedienungseinheit der Haushalt-Geschirrspülmaschine oder im Bereich des Deckels angeordnet sein.According to a further feature of the invention, the float acts on a display device that emits an optical or acoustic signal. Alternatively, the display device can be arranged on an operating unit of the household dishwasher or in the area of the cover.

Erfindungsgemäß ist der Schwimmer mit einer Auslösevorrichtung versehen, die auf eine Schaltvorrichtung einwirkt, die unmittelbar oder mittelbar die Anzeigevorrichtung schaltet.According to the invention, the float is provided with a triggering device which acts on a switching device which switches the display device directly or indirectly.

Nach einer Ausführungsform der Erfindung ist die Auslösevorrichtung des Schwimmers ein Permanent-Magnet, der einen außerhalb des Salzbehälters angeordneten, als Schaltvorrichtung dienenden magnetisch schaltbaren Schalter schaltet. Dieser magnetisch schaltbare Schalter ist am Wassereinlaufbehälter höhenverstellbar angebracht.According to one embodiment of the invention, the triggering device of the float is a permanent magnet which switches a magnetically switchable switch which is arranged outside the salt container and serves as a switching device. This magnetically switchable switch is attached to the water inlet tank in a height-adjustable manner.

Nach einer weiteren Ausführungsform der Erfindung ist die Auslösevorrichtung des Schwimmers eine einstückig an dem Schwimmer angeordnete Schaltnocke, die einen in den Einfüllstutzen des Salzbehälters ragenden Hebel eines als Schaltvorrichtung dienenden Mikroschalters beaufschlagt.According to a further embodiment of the invention, the triggering device of the float is a switch cam which is arranged in one piece on the float and which acts on a lever of a microswitch serving as a switching device which projects into the filler neck of the salt container.

Zweckmäßigerweise unterbricht der magnetisch schaltbare Schalter oder der Mikroschalter in der zumindest Salzsolevorrat anzeigenden Stellung des Schwimmers den Stromkreis zur Anzeigevorrichtung.The magnetically switchable switch or the microswitch expediently interrupts the circuit to the display device in the position of the float which indicates at least brine.

Diese Maßnahmen zeigen alternative Ausführungen einer mittelbaren Schaltung der Anzeigevorrichtung.These measures show alternative designs of an indirect switching of the display device.

Die unmittellbare Schaltung der Anzeigevorrichtung wird nach einer bevorzugten Ausführungsform der Erfindung dadurch erreicht, daß die Wippe als Schaltvorrichtung und als Anzeigevorrichtung ausgebildet ist und daß die Wippe mit einem als Anzeigevorrichtung dienenden Zeiger ausgestattet ist, der in der zumindest Salzsolevorrat anzeigenden Stellung des Schwimmers durch einen Durchbruch des Deckels ragt.The immediate switching of the display device is achieved according to a preferred embodiment of the invention in that the rocker is designed as a switching device and as a display device and that the rocker is equipped with a pointer serving as a display device, which in the at least brine-indicating position of the float through a breakthrough of the lid protrudes.

Vorzugsweise ist in dem Wassereinlaufbehälter im Bereich der Wippe und des Schwimmers eine Abdeckung und eine Schottrippe angeordnet.A cover and a bulkhead are preferably arranged in the water inlet container in the area of the rocker and the float.

Diese Schutzvorrichtung verhindert in dem geschützten Bereich das Eindringen des eingeschütteten Salzes und damit Funktionsstörungen der erfindungsgemäßen Anordnung.This protective device prevents penetration of the poured salt in the protected area and thus malfunctions of the arrangement according to the invention.

Mit der vorbeschriebenen Erfindung wird eine Falschanzeige des Füllzustandes des Salz- bzw. Salzsolestandes in den schon erwähnten Fällen des Nachfüllens von Salz durch den Benutzer oder bei nicht benutzten Wasserenthärtungsvorrichtung wirkungsvoll verhindert. Da nach dem Auflösen des Salzes der durch das Salz festgelegte Schwimmer wieder freigegeben wird, kann er dann den Füllzustand aufgrund seiner eigentlichen Funktion als Auftriebskörper entsprechend der Dichte der Salzsolelösung erfüllen. Die Salzmangelanzeige nach Verbrauch des eingefüllten Salzes wird durch die erfindungsgemäßen Maßnahmen nicht berührt.With the above-described invention, a false indication of the filling status of the salt or salt brine level is effectively prevented in the aforementioned cases of salt refilling by the user or when the water softening device is not used. Since the float defined by the salt is released again after the salt has been dissolved, it can then fulfill the filling state due to its actual function as a buoyancy body in accordance with the density of the brine solution. The salt deficiency indicator after consumption of the filled salt is not affected by the measures according to the invention.

Die Fertigungskontrolle für den richtigen Einbau und die richtige Funktion der für die Salzmangelanzeige notwendigen Teile kann durch Öffnen und Schließen des Dekkels auf einfache Weise erfolgen. Da bei der Fertigungskontrolle kein Salz eingefüllt wird, wird der Schwimmer beim vollständigen Schließen des Deckels durch die Wippe vollständig freigegeben und sinkt auf die zur Salzmangelanzeige führende Stellung ab, so daß also bei richtigem Einbau und richtiger Funktion der zu prüfenden Anordnung während des Schließen des Deckels eine Anzeige von Salzsolevorrat und bei vollständig geschlossenem Deckel eine Salzmangelanzeige erfolgen muß.The production control for the correct installation and the correct function of the parts necessary for the salt deficiency indicator can be easily done by opening and closing the lid. Since no salt is poured in during production control, the float is completely released by the rocker when the lid is fully closed and drops to the position leading to the salt deficiency indicator, so that when the lid is properly installed and functioning correctly, the arrangement to be tested is closed a display of brine and if the lid is completely closed, a salt deficiency indicator must be displayed.
