Der Erfindung liegt die Aufgabe zugrunde, bei einer Geschirrspülmaschine der in Rede stehenden Art Maßnahmen zu treffen, durch welche das Reinigungsmittel ohne zu verkleben für mehrere Spülgänge bevorratet und dosiert ausgegeben werden kann.The invention has for its object in a dishwasher take measures of the kind in question, through which the detergent for several without sticking Rinses can be stored and dispensed in doses.
Die Lösung dieser Aufgabe gemäß der Erfindung ist im kennzeichnenden
Teil des Anspruches 1 angegeben.The solution to this problem according to the invention is in the characterizing
Part of
Bei einer Ausgestaltung einer Geschirrspülmaschine gemäß der Erfindung werden Reinigungsmitteltabletten in einer Menge, die für mehrere komplette Geschirrspülprogrammabläufe ausreicht, manuell in einen Vorratsbehälter eingebracht, aus dem durch ein zugeordnetes Dosiergerät nur die für den jeweiligen Geschirr-Reinigungsprogrammablauf erforderliche Anzahl von Tabletten aus dem Vorrat vereinzelt und programmgerecht in den jeweiligen Spülprogrammabschnitt ausgegeben wird. Je Spülgang können dabei eine oder auch mehrere Tabletten in die Spülflüssigkeit ausgegeben werden, wobei die Menge von der Wasserhärte, dem Verschmutzungsgrad der Spülflüssigkeit und dergleichen programmabhängig gesteuert sein kann. Aufgrund des großen Volumens, welches insbesondere der Vorratsbehälter für das in Tablettenform vorliegende Geschirreinigungsmittel aufweisen muß, ist die Dosiervorrichtung vorzugsweise losgelöst von der den Arbeitsbehälter verschließenden Tür innerhalb des Arbeitsbehälters angeordnet und mit Steuermitteln gekoppelt, wobei ein Teil der notwendigen Steuermittel der Dosiervorrichtung zugeordnet und der andere Teil der Steuermittel außerhalb des Arbeitsbehälters angeordnet ist, wobei beide Teile der Steuermittel miteinander gekoppelt sind, um Antriebs- und/oder Steuersignale für das Dosiergerät zu übertragen. Die Kopplung kann dabei rein drahtlos erfolgen, wofür sich Funk- und/oder Ultraschall- und/oder Lichtenergie eignen bzw. eine kapazitive oder induktive Kopplung mittels eines geteilten Wechselstromübertragers möglich ist. Über diese Kopplung kann die für den mechanischen Antrieb erforderliche Energie und ggf. zusätzlich auch ein Steuersignal übertragen werden. Reicht die drahtlos übertragene Energie für eine unmittelbare Ansteuerung des Dosiergeräts nicht aus, kann das Dosiergerät mit einem elektrischen Energiespeicher ausgestattet sein, der durch die drahtlose Speisung übertragene geringe elektrische Energie speichert und erst nach Auftreten eines Steuersignals das Dosiergerät speist. Zusätzlich oder alternativ können jedoch auch mechanische Steuermittel vorgesehen sein, die von einer außerhalb des Arbeitsbehälters angeordneten Antriebseinrichtung betätigt werden und die für die Betätigung des Dosiergeräts notwendigen mechanischen Kräfte auf den Dosiermechanismus übertragen. Die Dosiervorrichtung kann an einem Geschirrkorb angebracht werden, wo sie in besonders einfacher Weise durch Herausziehen desselben frei zugänglich ist, wenn Tabletten nachgefüllt oder der Tablettenvorrat kontrolliert werden soll. Die Dosiervorrichtung ist dabei insbesondere lösbar angebracht, um evtl. notwendige Reparaturen oder Reinigungsvorgänge in einfacher Weise daran vornehmen zu können. Die Dosiervorrichtung kann jedoch auch an einer Wand des Arbeitsbehälters angebracht sein, wobei hier der Vorteil besteht, daß dann die Koppelmittel eng zueinander angeordnet werden können und eine zuverlässige Energieübertragung möglich wird. Ein geringer Abstand zwischen den Koppelmitteln ist dabei insbesondere bei induktiver oder kapazitiver Kopplung von Vorteil. Die Lösbarkeit ist auch in diesem Fall gegeben. Als Anbringungsort für die Dosiervorrichtung eignet sich dabei der Boden des Arbeitsbehälters unterhalb des unteren Geschirrkorbes im Eckbereich, wo der rotierende Sprüharm nicht hinreicht und der zur Verfügung stehende Raum für die Aufnahme von Spülgut nicht beeinträchtigt wird. Bei induktiver Kopplung ist es zweckmäßig, eine geteilte wechselstromgespeiste Spule eines elektrischen Übertragers vorzusehen, von dem eine Spule in der Dosiervorrichtung und die andere im Arbeitsbehälter oder bei nicht magnetischer Behälterwandung außerhalb derselben angebracht sein kann. Dabei ist es möglich, über einen Spulensatz die Energieübertragung wie die Steuersignale zu übertragen, wenn hierfür getrennte Signale erforderlich sind. Es ist jedoch auch möglich, zwei oder mehrere Spulensätze vorzusehen, über die im Bedarfsfall unterschiedliche elektrische Signale übertragen werden können.In one embodiment of a dishwasher according to the Invention detergent tablets are available in an amount that sufficient for several complete dishwasher programs, manually placed in a storage container from which through a assigned dosing device only those for the respective dishes cleaning program sequence required number of tablets the stock individually and according to the program in the respective Rinsing program section is issued. Each rinse can dispensed one or more tablets into the rinsing liquid the amount of water hardness, the degree of pollution the rinsing liquid and the like depending on the program can be controlled. Because of the large volume which especially the storage container for that in tablet form The present dishwashing detergent must be the dosing device preferably detached from the work container locking door inside the Work container arranged and with tax funds coupled, with part of the necessary control means of Dosing device assigned and the other part of the Control means is arranged outside the work container, wherein both parts of the control means are coupled together are to drive and / or control signals for the Transfer dosing device. The coupling can be pure done wirelessly, for which radio and / or ultrasound and / or Suitable light energy or a capacitive or inductive coupling by means of a split AC transformer is possible. About this coupling can the energy required for the mechanical drive and possibly also transmit a control signal become. Is the wirelessly transmitted energy enough for one direct control of the dosing device can not the dosing device with an electrical energy storage be equipped by the wireless feed low electrical energy transferred and stores the dosing device feeds after a control signal occurs. Additionally or alternatively, however, mechanical Control means may be provided by an outside of the Work container arranged drive device actuated be and for the operation of the dosing device necessary mechanical forces on the dosing mechanism transfer. The metering device can be on one Dish rack can be attached wherever in particular simply by pulling it out freely is accessible when tablets are refilled or the Tablet supply should be checked. The Dosing device is in particular detachably attached, to possibly necessary repairs or cleaning processes in easy way to do it. The Dosing device can also on a wall of the Work container be attached, which is the advantage there is that then the coupling means closely to each other can be arranged and reliable Energy transfer becomes possible. A short distance between the coupling means is particularly at Inductive or capacitive coupling is an advantage. The Solvability is also given in this case. As The location for the dosing device is suitable the bottom of the work tank below the bottom Crockery basket in the corner area where the rotating spray arm not enough and the space available for the Absorption of wash ware is not impaired. At inductive coupling it is appropriate to use a split AC-fed coil of an electrical transformer provide a coil in the metering device and the other in the working container or in the case of non-magnetic Container wall can be attached outside the same. It is possible to use a coil set Power transmission to transmit like the control signals if separate signals are required for this.

Die Erfindung ist nachfolgend anhand der Zeichnungen von Ausführungsbeispielen näher erläutert.The invention is based on the drawings of Exemplary embodiments explained in more detail.
Es zeigen:
Eine Dosiervorrichtung 1 umfaßt manuell einen zu
beschickenden, verschließbaren Vorratsbehälter für
tablettenförmiges Reinigungsmittel und ein zugeordnetes
Dosiergerät mit Steuermitteln für die gesteuerte Ausgabe
von einer oder mehreren Tabletten während eines Vorspül- oder
Reinigungsganges im Programmablauf einer
Geschirrspülmaschine. Der der Dosiervorrichtung 1
zugeordnete Teil der Steuermittel ist mit dem weiteren für
die Steuerung notwendigen Teil der Steuermittel außerhalb
des Arbeitsbehälters der Geschirrspülmaschine angeordnet
und vorzugsweise drahtlos mit dem ersten Teil der
Steuermittel in der Dosiervorrichtung gekoppelt. Die
drahtlose Kopplung eignet sich insbesondere dann, wenn die
Dosiervorrichtung 1 einem aus dem Arbeitsbehälter zumindest
teilweise herausfahrbaren Geschirrkorb 2 vorzugsweise
lösbar zugeordnet ist. Dagegen ist eine drahtgebundene
Koppelleitung dann möglich, wenn die Dosiervorrichtung 1
gemäß Fig. 2 getrennt vom Geschirrkorb 2 an einer Wand des
Arbeitsbehälters ggf. lösbar festgesetzt ist. In diesem
Falle ist es auch möglich, die Kopplung über mechanische
Steuermittel vorzusehen, nachdem dann eine vorgegebene
Position der Dosiervorrichtung 1 innerhalb des
Arbeitsbehälters gegeben ist und ein Steuerschieber oder
dgl. als Koppelglied zielgenau auf die der
Dosiervorrichtung zugeordneten Teile der ersten
Steuermittel gerichtet werden kann. Vorzugsweise ist die
Dosiervorrichtung 1 am Boden des Arbeitsbehälters im
Bereich einer Ecke angeordnet, wohin ein drehbar gelagerter
Sprüharm nicht reicht. Es geht dann kein Raum für die
Unterbringung von zu spülenden Gut im Geschirrkorb 2
verloren und auch die Funktion des Sprüharms wird nicht
beeinflußt. Die Anordnung der Dosiervorrichtung 1 im
Eckbereich nahe der Tür ermöglicht dann eine gute
Zugänglichkeit bei auf die Tür ausgefahrenem unterem
Geschirrkorb 2. Die Dosiervorrichtung 1 kann jedoch auch an
der Unterseite des Geschirrkorbes 2 ebenfalls lösbar und
ggf. mit Abstand festgesetzt sein, so daß in diesem Bereich
des Geschirrkorbes 2 zumindest solche Spülgutteile
aufgelegt werden können, die nicht oder wenig durch
Gitterstäbe des Geschirrkorbes 2 nach unten stehen. Diese
Anbringungsart ist auch dann von Vorteil, wenn die Kopplung
der Steuermittel optisch, induktiv oder kapazitiv erfolgt,
weil dann die Dosiervorrichtung so angeordnet werden, daß
sie mit den ihr zugeordneten Kopplern der Steuermittel nahe
an die benachbarte Seitenwand des Arbeitsbehälters
herangeführt werden kann, welche die entsprechenden
Koppelmittel des anderen Steuerteils trägt. Die Anordnung
der Dosiervorrichtung 1 kann dann vorzugsweise am Oberkorb
einer Geschirrspülmaschine erfolgen, deren zugeordneter
Sprüharm mittels eines mit Spülflüssigkeit gespeistem
Tragrohres 3 mit Spülflüssigkeit versorgt wird und das
durch eine Seitenwand des Arbeitsbehälters hindurchgeführt
ist sowie unterhalb des Geschirrkorbes den notwendigen
Sprüharm trägt und speist.A
