Die Erfindung betrifft ferner eine Waschmaschine, umfassend einen Laugenbehälter zur Aufnahme von Waschflüssigkeit und eine Steuereinereinrichtung, mit einer Dosiereinrichtung, die entfernt von der Waschmaschine angeordnet werden kann, die über zwei Schlauchleitungen mit der Waschmaschine verbunden ist und mit der Steuereinrichtung der Waschmaschine in Wirkverbindung steht.The invention further relates to a washing machine, comprising a tub for receiving washing liquid and a control device, with a metering device, which can be arranged away from the washing machine, which is connected via two hose lines to the washing machine and is in operative connection with the control device of the washing machine.
In Waschmaschinen für den Haushalt wird üblicherweise das Waschmittel von Hand in eine Kammer gegeben, die nach dem Start des Waschprogramms mit Wasser ausgespült und in den Laugenbehälter eingelassen wird. Der Benutzer muss hierbei die Dosiervorschriften für das jeweils verwendete Waschmittel einhalten und darauf achten, dass er die richtige Menge in die Kammer einfüllt. Um die Beschickung mit Waschmittel oder sonstigen Zugabemitteln, zu vereinfachen, werden automatische Dosiereinrichtungen verwendet, in denen in einem Vorratsbehälter eine größere Menge Waschmittel gelagert ist. Beim Start eines Waschprogramms wird dann die voreingestellte Waschmittelmenge der Waschflüssigkeit zugeführt, so dass der Benutzer nicht bei jedem Waschgang auf die einzufüllende Waschmittelmenge achten muss. Besonders bei gewerblich eingesetzten Waschmaschinen werden derartige Dosiereinrichtungen häufig verwendet.In domestic washing machines, the detergent is usually added by hand to a chamber, which is rinsed with water after starting the washing program and introduced into the tub. The user must comply with the dosing instructions for the detergent used in each case and make sure that he fills the correct amount in the chamber. In order to simplify the loading of detergent or other additives, automatic dosing devices are used, in which a reservoir in a larger amount of detergent is stored. When starting a washing program, the preset amount of detergent is then supplied to the washing liquid, so that the user does not have to pay attention to the amount of detergent to be filled in each wash cycle. Especially with commercially used washing machines such dosing devices are often used.

Der Erfindung liegt somit Aufgabe zugrunde, eine Dosiereinrichtung oder eine Waschmaschine dahingehend zu verbessern, dass auf einfache Weise eine genaue Dosierung bereitgestellt wird.The invention is therefore an object of the invention to improve a metering device or a washing machine to the effect that a precise dosage is provided in a simple manner.
Erfindungsgemäß wird die Aufgabe durch eine Dosiereinrichtung mit den Merkmalen des Patentanspruchs 1 und durch eine Waschmaschine mit den Merkmalen des Patentanspruchs 13 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen 2 bis 12 und 14 bis 17.According to the invention, the object is achieved by a metering device having the features of
Die mit der Erfindung erreichbaren Vorteile bestehen darin, dass eine mengengenaue Dosierung automatisch vorgenommen werden kann. Hierzu umfasst das Dosiermittel eine zylinderförmige Kammer mit einem darin enthaltenen Zellenrad mit mehreren durch Stege getrennte Kammersegmenten bzw. Zellen, das über eine vertikale Drehachse drehbar unterhalb des Bodens des Vorratsbehälters angeordnet ist. Der Boden des Vorratsbehälters besitzt eine Einlassöffnung zum Befüllen der Kammersegmente und auf der Unterseite eine Auslassöffnung zur Fördereinrichtung, wobei das Zellenrad mit der Drehachse des Rührwerks gekoppelt ist. Dadurch ist nur ein Elektroantrieb für das Rührwerk notwendig, welches durch die umlaufenden Messer das Einrieseln in die Kammer bzw. in ein Kammersegment bewirkt. Zumindest ein umlaufendes Messer ist nah am Boden des Vorratsbehälters angeordnet, so dass durch das Abstreifen des Pulvers oberhalb der Öffnung eine vollständige Befüllung einer Zelle erreicht wird. Durch das vorbekannte Volumen einer Zelle wird anhand der Anzahl der in die Fördereinrichtung zu entleerenden Zellen die zu dosierende Menge festgelegt. Die Kopplung ist so ausgeführt, dass sich ein Messer des Rührwerks mindestens einmal über die Einlassöffnung bewegt, bevor das Zellenrad sich weiterdreht. Die Richtungsangaben oder Positionsangaben beziehen sich auf die betriebsgemäße Aufstellposition der Dosiereinrichtung und Waschmaschine.The achievable with the invention advantages are that a precise dosage can be made automatically. For this purpose, the dosing means comprises a cylindrical chamber with a cellular wheel contained therein with a plurality of chamber segments or cells separated by webs, which is arranged rotatably via a vertical axis of rotation below the bottom of the reservoir. The bottom of the reservoir has an inlet opening for filling the chamber segments and on the bottom of an outlet opening to the conveyor, wherein the cell wheel is coupled to the axis of rotation of the agitator. As a result, only an electric drive for the agitator is necessary, which causes by the rotating blades trickling into the chamber or in a chamber segment. At least one rotating knife is arranged close to the bottom of the reservoir, so that by the stripping of the powder above the opening, a complete filling of a cell is achieved. Due to the known volume of a cell, the quantity to be dispensed is determined on the basis of the number of cells to be emptied into the conveyor. The coupling is designed so that a blade of the agitator moves over the inlet opening at least once before the cellular wheel continues to rotate. The directions or position information refer to the operating position of the metering device and washing machine.
In einer zweckmäßigen Ausführung ist die Drehachse des Zellenrades beabstandet zur Drehachse des Rührwerks angeordnet, wobei die Einlassöffnung und die Auslassöffnung jeweils etwa der Form eines Kammersegments entsprechen, und die Einlassöffnung nah zur Achse des Rührwerks und die Auslassöffnung entfernt zur Achse des Rührwerks angeordnet ist. Dadurch ist sichergestellt, dass das Behandlungsmittel sicher und vollständig jeweils in eine Zelle eingefüllt und erst nach dem Weiterdrehen des Zellenrades aus der Zelle in die Fördereinrichtung gefüllt wird. Es kann somit kein Behandlungsmittel durch die Kammer hindurchrieseln, was zu einer erhöhten Zugabemenge führen würde. Die genaue Dosierung erfolgt deshalb unabhängig vom Rieselverhalten oder vom Anbackverhalten des Behandlungsmittels.In an expedient embodiment, the axis of rotation of the cellular wheel is arranged at a distance from the axis of rotation of the agitator, wherein the inlet opening and the outlet opening each correspond approximately to the shape of a chamber segment, and the inlet opening is arranged close to the axis of the agitator and the outlet opening is remote from the axis of the agitator. This ensures that the treatment agent is safely and completely filled in each case in a cell and filled only after further rotation of the cell wheel from the cell into the conveyor. Thus, no treatment agent can trickle through the chamber, which would lead to an increased amount of added. The exact dosage is therefore independent of the trickle or the baking behavior of the treatment agent.
In einer zweckmäßigen Ausführung umfasst die Fördereinrichtung eine Laugenpumpe und eine Mischkammer zur Aufnahme des zu dosierenden Behandlungsmittels, wobei das in der Mischkammer eingelassene Behandlungsmittel mittels des zulaufenden Wassers ausgespült und mit der Laugenpumpe zur Waschmaschine gefördert werden kann. Dadurch kann die Dosiereinrichtung wahlfrei aufgestellt werden. Auch eine Aufstellung neben der Waschmaschine oder darunter ist möglich, da durch die Laugenpumpe sichergestellt ist, dass das mit Behandlungsmittel versetzte Wasser unabhängig von der Schwerkraft in die Waschmaschine gelangt.In an expedient embodiment, the conveying device comprises a drain pump and a mixing chamber for receiving the treatment agent to be metered, wherein the treatment agent let into the mixing chamber can be flushed out by means of the incoming water and conveyed to the washing machine with the drain pump. As a result, the metering device can be set up optionally. Also, a list next to the washing machine or below is possible because it is ensured by the drain pump that the treated with treatment agent water enters the washing machine regardless of gravity.
Zur Kopplung des Zellenrades ist es zweckmäßig, an der Achse des Rührwerks zumindest einen Mitnehmer anzubringen, die in eine Öffnung in die Kammer ragen kann und dabei mit einem Steg zusammenwirkt, wodurch das Zellenrad um eine Teildrehung bewegbar ist.
