Abstract

Monitor for the liq. flow system in (dish) washing machines has a leak water collection chamber provided in the trough-shaped equipment base. A float is arranged in the collection chamber and actuates a switch circuit, when leak water is entering the equipment base, to close the inlet valve to the machine and/or emit a warning signal. An actuating lever is pref. placed on the float. A magnet is provided to actuate the switch circuit by the actuating lever lifted in the region of attraction of the magnet by the float. The effective monitoring system for leak water or overflow prevents damage to the rooms housing the machines.

Description

Überwachungsvorrichtung für das Flüssigkeitsdurchlaufsystem in Wasch- oder Geschirrspülmaschinen Die Erfindung betrifft eine tlberwachungsvorrichtung für das Flüssigkeitsdurchlaufsystem in Wasch- oder Geschirrspülmaschinen. Monitoring device for the liquid flow system in washing or dishwashers. The invention relates to an oil monitoring device for the liquid flow system in washing machines or dishwashers.

Aus der DT-OS 1 926 791 ist eine Überwachungseinrichtung für den Wasserkreislauf einer Wasch- oder Geschirrspülmaschine bekannt, die aus in der Nähe des Bodens der Maschine angeordneten Flüssigkeitsfühlern und einer von den Flüssigkeitsfühlern beeinflußten elektronischen Schaltung besteht, welche beim Auftreten von Flüssigkeitslachen auf dem Fußboden des Wohnraumes die Maschine abschaltet und/oder ein Warnsignal erzeugt.From DT-OS 1 926 791 is a monitoring device for the water cycle a washing machine or dishwasher known that from near the bottom of the Liquid sensors arranged in the machine and one of the liquid sensors influenced electronic circuitry, which occurs when puddles of liquid occur the machine switches off and / or a warning signal on the floor of the living room generated.

Aufgabe der Erfindung ist es eine Überwachungsvorrichtung für Wasch- und Geschirrspülmaschinen zu schaffen, die verhindert, daß durch undicht gewordene Wasserführungsleitungen oder durch ein Überlaufen des Waschbehälters Wasserschäden im Aufstellungsraum der Maschine, insbesondere in Wohnungen entstehen.The object of the invention is a monitoring device for washing and to create dishwashers that prevent leaks through Water ducts or water damage from overflowing the washing container occur in the room where the machine is installed, especially in apartments.

Erfindungsgemäß wird dies dadurch erreicht, daß in einem muldenförmigen Geräteboden ein Leckwasser-Sammelraum vorgesehen ist, ferner im Sammelraum ein Schwimmer angeordnet ist und daß schließlich eine vom Schwimmer beeinflußbare Schaltvorrichtung beim Auftreten von Leckwasser auf dem Geräteboden das Einlaßventil der Maschine schließt und/oder ein Warnsignal auslöst.According to the invention this is achieved in that in a trough-shaped A leakage water collecting space is provided on the bottom of the device, and a float is also provided in the collecting space is arranged and that finally a switching device that can be influenced by the float the inlet valve of the machine in the event of water leakage on the bottom of the device closes and / or triggers a warning signal.

In vorteilhafter Weise sind damit Schäden im Flüssigkeitsdurchlauf system einer Wasch- oder Geschirrspülmaschine ohne Verwendung komplizierter und teuerer elektronischer Bauteile bereits im Gerät erfaßbar, ohne daß eine schon schädliche Lachenbildung auf dem Wohnungsfußboden Voraussetzung für das Ansprechen der Überwachungsvorrichtung ist.Advantageously, there is thus damage in the fluid flow system of a washing machine or dishwasher without the use of complicated and expensive electronic components can already be detected in the device without an already harmful one Pool formation on the apartment floor is a prerequisite for the monitoring device to respond is.

Die Erfindung wird nachstehend anhand zweier in der Zeichnung dargestellter Ausführungsbeispiele näher erläutert.The invention is illustrated below with reference to two in the drawing Embodiments explained in more detail.

Es zeigen: Fig. 1 eine schematische Darstellung der wesentlichen Teile einer Waschmaschine mit einer erfindungsgemäßen t)terwachungsvorrichtung, Fig. 2 eine Ausführung der flberwachungsvorrichtung, bei der nach einem geringen Hub des Schwimmers durch das in den Sammelraum laufende Leckwasser ein auf dem Schwimmer ruhender Betätigungshebel in den Anzugsbereich eines Magneten kommt, der dann die Schaltung eines Sicherheitsschalters übernimmt.1 shows a schematic representation of the essential parts a washing machine with a monitoring device according to the invention, FIG. 2 a version of the monitoring device in which, after a small stroke of the Float through the leakage water running into the collecting chamber to the Float-resting operating lever comes into the area of attraction of a magnet, which then takes over the switching of a safety switch.

Wie aus Fig. 1 ersichtlich, sind von einer Waschmaschine teilweise das Gehäuse 1, das durch Federbeine 2 getragene Antriebsaggregat mit Laugenbehälter 3 und Antriebsmotor 4 dargestellt.As can be seen from Fig. 1, are partially of a washing machine the housing 1, the drive unit supported by struts 2 with a tub 3 and drive motor 4 shown.

Im Unterteil des Gehäuses 1 ist ein muldenförmiger Geräteboden 5 vorgesehen, der in einer Ausformung am Muldenboden einen Leckwasser-Sammelraum 6 bildet. Tritt im Flüssigkeitsdurchlaufsystem eine Undichtheit auf, wird z.B. eine Wasserführungsleitung der Maschine undicht oder läuft der Behälter 3 durch Versagen eines Niveauwächters oder dgl. über, so gelangt Leckwasser in den Sammelraum 6 des Gerätebodens 5 und bewirkt ein Anheben eines darin angeordneten Schwimmers 7, der eine Schaltvorrichtung beeinflußt, wodurch ein nicht gezeigtes Einlaßventil der Maschine geschlossen und/ oder eine ebenfalls nicht dargestellte Warnanlage zur Auslösung eines Warnsignals eingeschaltet wird.In the lower part of the housing 1, a trough-shaped device base 5 is provided, which forms a leakage water collecting space 6 in a recess on the trough bottom. Kick If there is a leak in the liquid flow system, e.g. a water conduit becomes the machine leaks or the container 3 runs due to the failure of a level monitor Or the like. About, so leak water gets into the collecting space 6 of the device bottom 5 and causes a float 7 arranged therein, which is a switching device, to be raised influenced, whereby a not shown inlet valve of the machine closed and / or a warning system, also not shown, for triggering a warning signal is switched on.

Nach der Ausführung gemäß Fig. 1 wird dabei durch den vom Leckwasser angehobenen, z.B. aus EunstschaumstoPf bestehenden Schwimmer 7 ein an einem Lagerbock 8 des Gerätebodens 5 angeordneter Mikroschalter 9 oder dgl. direkt oder über einen Hebel, vorzugsweise einen Winkelhebel 10 mit unterschiedlich langen Hebelarmen betätigt.According to the embodiment according to FIG. 1, it is by the leakage water raised float 7, e.g. made of synthetic foam, is attached to a bearing block 8 of the device bottom 5 arranged microswitch 9 or the like. Directly or via a Lever, preferably an angle lever 10 operated with lever arms of different lengths.

Gemäß dem Ausführungsbeispiel nach Fig. 2 ist ein Schwimmer 7, auf dem in der Normallage der Betätigungshebel 10 ruht, und ein Magnet 11 vorgesehen. Wird bei dieser Ausführung der Schwimmer und damit der aus magnetisierbarem Material bestehende Betätigungshebel 10 durch das Leckwasser geringfügig beispielsweise etwa 2 - 3 mm angehoben, so gelangt der Hebel 10 in den Anzugsbereich des Magneten 11 und es wird durch den vom Magneten angezogenen Hebel der Mikroschalter 9 betätigt. Damit wird erreicht, daß die Schaltvorrichtung mit geringer Auftriebskraft des Schwimmers betätigbar ist und daß die Uberwachungsvorrichtung bereits bei kleinen Leckwassermengen ansprechen kann.According to the embodiment of FIG. 2, a float 7 is on which rests in the normal position of the operating lever 10, and a magnet 11 is provided. Is used in this execution the float and thus the magnetizable one Material existing operating lever 10 by the leakage water slightly for example Raised about 2-3 mm, the lever 10 comes into the area of attraction of the magnet 11 and the microswitch 9 is actuated by the lever attracted by the magnet. This ensures that the switching device with a low buoyancy force of the swimmer can be actuated and that the monitoring device is already used in the event of small amounts of leakage water can address.

Nach einer weiteren Ausbildung wäre es auch möglich, daß der Schwimmer 7 einen Eisenkern 12 trägt und direkt mit dem Magneten zur Ausführung des Schaltvorgangs zusammenwirkt.After further training it would also be possible that the swimmer 7 carries an iron core 12 and directly to the magnet to carry out the switching process cooperates.
