Description

Die Erfindung bezieht sich auf eine Waschmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a washing machine according to the preamble of claim 1.

Aus der DE-PS 15 85 797 ist eine Waschmaschine bekannt, die mit einer Enthärtungseinrichtung ausgerüstet ist. Durch den zusätzlichen Einbau eines Enthärters ist es hierbei möglich, die Waschgänge mit Weichwasser und die Spülgänge mit Hartwasser durchzuführen. Wenn für den Waschprozeß weiches Wasser zur Verfügung steht, bringt dies den Vorteil, daß man mit einer geringeren Menge Waschmittel auskommt Besonders in Gegenden, die nur über sehr hartes Leitungswasser verfügen, wäre die Ausrüstung der Waschmaschine mit einem Enthärter wünschenswert.From DE-PS 15 85 797 a washing machine is known which is equipped with a softening device. The additional installation of a softener makes it possible to carry out the wash cycles with soft water and the rinse cycles with hard water. If soft water is available for the washing process, this has the advantage that a smaller amount of detergent can be used. Especially in areas that have very hard tap water, equipping the washing machine with a softener would be desirable.

Während sich der Einsatz einer Enthärtungseinrichtung auf dem Spülmaschinensektor durchgesetzt hat und üblich ist, ist der Einbau von Enthärtungseinrichtungen in Waschmaschinen bislang ohne praktische Bedeutung geblieben. Die Gründe dafür liegen im weserttlichen darin, daß zusätzliche Teile im ohnehin schon reichlich ausgefüllten Gehäuse der Maschine untergebracht werden müssen und daß die Bevorratung und Zugabe von Salz einen weiteren Bedienungsaufwand nach sich ziehtWhile the use of a softening device has established itself in the dishwasher sector and is common, the installation of softening devices in washing machines has so far been of no practical importance. The reasons for this lie essentially in the fact that additional parts have to be accommodated in the already abundantly filled housing of the machine and that the storage and addition of salt entails a further operating effort

Der Erfindung liegt die Aufgabe zugrunde, eine Waschmaschine zu schaffen, bei der die für die Enthärtungseinrichtung notwendigen Teile in einer bestehenden Waschmaschinenkonzeption innerhalb des Gehäuses integriert werden können und daß sich für den Benutzer trotzdem noch eine leichte Bedienbarkeit und Zugabe der Behandlungsmittel ergibt Weiterhin sollen neben der Enthärtungseinrichtung zusätzliche Vorkehrungen getroffen werden, um eine noch weitergehende Reduzierung der eingesetzten Waschmittel zu erreichen.The invention has for its object to provide a washing machine in which the parts necessary for the softening device can be integrated into an existing washing machine concept within the housing and that the user is still easy to use and add the treatment agent Additional precautions are to be taken in order to achieve a further reduction in the detergent used.

Die Lösung dieser Aufgabe wird durch die im Hauptanspruch gekennzeichneten Merkmale erzielt Weitere erfindungsgemäße Merkmale ergeben sich aus Anspruch 2. Vorteilhafte Ausgestattungen sind in den nachfolgenden Unteransprüchen aufgeführtThis object is achieved by the features characterized in the main claim. Further features according to the invention result from claim 2. Advantageous configurations are listed in the following subclaims

Die Vorteile der erfindungsgemäßen Lösung bestehen insbesondere darin, daß man von Geschirrspülmaschinen her bewährte Enthärtungseinrichtungen nur leicht abwandeln muß, damit sie für den Einsatz in einer Waschmaschine geeignet sind und daß der Benutzer trotzdem noch eine zentrale Zugabeskelle an der Maschine vorfindet bei der er sämtliche Wasch- und Behandlungsmittel einfüllen kann.The advantages of the solution according to the invention are in particular that softening devices which have been tried and tested in dishwashers only have to be modified slightly so that they are suitable for use in a washing machine and that the user still finds a central addition trowel on the machine in which he has all the washing and fill treatment agents.

Die erfindungsgemäß ausgebildete Waschmaschine zeichnet sich darüber hinaus durch einen besonders sparsamen Waschmittehrerbrauch aus. Während des Einspülvorgangs kann kein Waschmittel unausgenutzt in das Ablaufsystem gelangen.The washing machine designed according to the invention is also characterized by a particularly economical use of detergent. No detergent can get into the drain system unused during the induction process.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen rein schematisch dargestellt.Embodiments of the invention are shown purely schematically in the drawings.

  • Fig. 2 also the water flow diagram of a drum washing machine as shown in FIG. 1 with additional precautions in the drain elements to prevent loss of detergent.

Der Wasserzulauf zur Maschine wird von den Magnetventilen (1) für Kaltwasser und vom Magnetventil (2) für Warmwasser vom Programmschaltwerk gesteuert. Zur Enthärtungseinrichtung sind im wesentlichen die Wasserkammer (3), der Enthärter (4) und das Salzgefäß (5) zu zählen. Die Wasserkammer (3) ist, wie von Geschirrspülmaschinen bekannt, mit einer integrierten Rücksaugverhinderung versehen. Je nachdem welches Steuerungsverfahren für die Wassermenge zum Regenerieren angewendet wird, kann die Wasserkammer (3) als Wasservorraisbehälter (Schwerkraftprinzip) oder als Durchflußbehälter (Zeitsteuerungsprinzip) dienen. Der Laugenbehälter (6) der Maschine nimmt die Wäschetrommel (7) auf und ist über den Laugenbehälterablauf (8) mit der Ablaufpumpe (9) verbunden. Die Waschmittelzugabe erfolgt über den Einspülkasten (10).The water supply to the machine is controlled by the solenoid valves (1) for cold water and the solenoid valve (2) for hot water from the program switch. The water chamber (3), the softener (4) and the salt vessel (5) are to be counted as essential for the softening device. As is known from dishwashers, the water chamber (3) is provided with an integrated back suction prevention. Depending on which control method is used for the amount of water for regeneration, the water chamber (3) can serve as a water pre-storage tank (gravity principle) or as a flow tank (time control principle). The tub (6) of the machine receives the laundry drum (7) and is connected to the drain pump (9) via the tub drain (8). The detergent is added via the dispenser drawer (10).

Der Enthärter (4) steht mit dem Einspülkasten (10) über eine Leitung (11) in Verbindung. In diese Leitung (11) ist ein Abzweig (12) zwischengeschaltet, von dem aus eine Verbindungsleitung (13) zur Ablaufpumpe (9) führt.The softener (4) is connected to the induction bowl (10) via a line ( 1 1). A branch (12) is interposed in this line ( 1 1), from which a connecting line (13) leads to the drain pump (9).

Der Enthärter (4) und das Satzgefäß (5) stehen mit der Wasserkammer (3) in üblicher Weise über Leitungen (14 und 15) in Verbindung. Der Einfüllstutzen (16) für das Salzgefäß (5) wird in vorteilhafter Ausbildung bis in den oberen Deckelbereich der Maschine geführt wobei er vorzugsweise in der Nähe des EinspOlkastens (10) für den Benutzer zugänglich wird.The softener ( 4 ) and the set vessel (5) are connected to the water chamber (3) in the usual way via lines (14 and 15). In an advantageous embodiment, the filler neck (16) for the salt vessel (5) is guided up to the upper lid area of the machine, and is preferably accessible to the user in the vicinity of the feed box (10).

In der Fig. 2 ist in einer Weiterbildung der Erfindung ein im Laugenbehälterablauf (8) angeordneter Auftriebskörper (23) angeordnet. In der Ablaufleitung (24) ist ein Wasserreservoir (25) gebildet, welches innerhalb des Maschinegehäuses an einer über dem üblichen Waserstand des Laugenbehälters (6) gelegenen Stelle angebracht ist2, in a further development of the invention, a buoyancy body (23) arranged in the tub drain (8) is arranged. A water reservoir (25) is formed in the drain line (24), which is attached inside the machine housing at a location above the usual water level of the tub (6)

Die Funktion der in der Fig. 1 gezeigten Anordnung ist wie folgtThe function of the arrangement shown in Fig. 1 is as follows

Der Waschprozeß wird mit weichem Wasser durchgeführt. Hierzu wird wames oder kaltes Wasaer oder beides gemischt über die Leitung (19) in die Wasserkammer (3) geleitet. In dieser Wasserkammer (3) bildet sich ein Wasserreservoir und über die Leitung (14) wird der Enthärter (4) beaufschlagt Das Weichwasser verläßt den Enthärter über die Leitungen (17,11) und wird in den Einspülkasten (10) geführt, wo das Waschmittel für den Vor-oder Hauptwaschgang ausgespült und in den Laugenbehälter (6) geleitet wird.The washing process is carried out with soft water. For this purpose, waxy or cold Wasaer or both are mixed and fed via the line (19) into the water chamber (3). A water reservoir forms in this water chamber (3) and the softener (4) is acted on via the line (14). The soft water leaves the softener via the lines (17, 11) and is fed into the dispenser drawer (10), where the detergent for the pre-wash or main wash and rinsed into the tub (6).

Da das ganze Spülprogramm oder zumindest die letzten Spülgänge mit Hariwasser durchgeführt werden, wird über die Leitung (18) und den Einspülkasten (10) eine direkte Einleitung in den Laugenbehälter (6) vorgenommen. Während nun das Spülprogramm abläuft, vollzieht sich der Regenerationsablauf des Enthärters (4) und zwar vorteilhaft während des Abpumpens zwischen zwei Spülgängen. Hierzu wird das Ventil (20) geöffnet und das in der Wasserkammer (3) gespeicherte Wasser läuft durch Schwerkraft über die Leitung (15) in das Salzgefäß (5) und drückt eine Salzsole in den Enthärter (4), in dem dann die Regeneration des Enthärters (4) einsetzt Das aus dem Enthärter verdrängte Restwasser läuft über die Leitung (17), den Abzweig (12) und die Leitung (13) direkt in die Ablaufpumpe (9).Since the entire rinsing program or at least the last rinse cycles are carried out with Hari water, direct introduction into the tub (6) is carried out via the line (18) and the induction bowl (10). While the rinsing program is now running, the regeneration process of the softener ( 4 ) takes place, advantageously during pumping between two rinsing cycles. For this purpose, the valve (20) is opened and the water stored in the water chamber (3) runs by gravity through the line (15) into the salt vessel (5) and presses a brine into the softener (4), in which the regeneration of the Softener (4) used The residual water displaced from the softener runs directly through the pipe (17), the branch (12) and the pipe (13) into the drain pump (9).

Das Ausspülen des regenerierten Enthärters (4) wird mit dem Abpumpen nach dem letzten Spülgang eingeleitet. Hierzu fließt über die Leitung (19), die Waserkammer (3) und die Leitung (14) Frischwasser durch den Enthärter (4) und drückt die Regenerationslösung über die Leitung (11) und den Einspülkasten (10) in den Ablauf der Maschine. Damit steht der Enthärter für die nächste Weichwasserentnahme des nachfolgenden Waschgangs zur Verfügung.Rinsing of the regenerated softener (4) is initiated by pumping out after the last rinse. For this purpose, fresh water flows through the line (19), the water chamber (3) and the line (14) through the softener (4) and presses the regeneration solution via the line (11) and the induction bowl (10) into the machine outlet. The softener is now available for the next soft water withdrawal of the subsequent wash cycle.

In den Leitungen (11 und 13) oder in dem Abzweig - (12) können selbsttätig oder vom Programmschaltwerk steuerbare Ventilanordnungen eingeschaltet sein, die den richtigen Wasserweg in der bestimmungsgemäßen Funktion steuern.In the lines (11 and 13) or in the branch - (12), valve arrangements that control the correct water path in the intended function can be switched on automatically or by the program switching mechanism.

Ein Wasserhärte-Umschalter (21) an der Wasserkammer (3) läßt eine Einstellmöglichkeit für unterschiedliche Härtebereiche zu. Wie üblich, steht die Wasserkammer (3) mit einer Entlüftüngsleitung (22) mit dem Wassereinlaufsystem der Maschine zwecks Entlüftung in Verbindung.A water hardness switch (21) on the water chamber (3) allows adjustment for different hardness ranges. As usual, the water chamber (3) is connected with a ventilation line (22) to the water inlet system of the machine for the purpose of ventilation.

Bei dem in der Fig. 2 dargestellten Ausführungsbeispiel ist die Funktion wei folgtIn the embodiment shown in FIG. 2, the function follows white

Auch hier wird im Waschgang über die Magnetventile (1 und/oder 2) der Wasserzulauf zur Wasserkammer (3) gesteuert. Von hier aus wird das Hartwasser in den Enthärter (4) geleitet, um von hier als Weichwasser über die Leitung (11) und geöffnetem Ventil (26) in den Einspülkasten (10) geführt zu werden. Dabei ist das Ventil - (27) in der Verbindungsleitung (13) geschiossen. Das für den Waschprozeß erforderliche Waschmittel wird aus dem Einspülkasten (10) in den Laugenbehälter (6) eingespült Während des Einspüivorgangs wird die Ablauföffnung des Laugenbehälters (6) durch den Auftriebskörper (23) verschlossen. Das aus dem vorherigen Waschprogramm in der Ablaufleitung (24) und dem Wasserreservoir (25) verbleibende Restwasser drückt nach dem Abschalten der Ablaufpumpe (9) den Auftriebskörper (23) in eine nicht näher gezeigte Dichtungsanordnung in der Laugenbehätteröffnung. Dadurch kann kein Waschmittel unausgenutzt in den Ablauf gelangen, so daß geringere Waschmittelmengen dosiert werden können.Here, too, the water supply to the water chamber (3) is controlled in the wash cycle via the magnetic valves (1 and / or 2). From here, the hard water is fed into the softener (4) in order to be fed from there as soft water via the line (11) and the open valve (26) into the induction bowl (10). The valve - (27) is closed in the connecting line (13). The detergent required for the washing process is flushed from the dispenser box (10) into the tub (6). During the dispensing process, the drain opening of the tub (6) is closed by the buoyancy body (23). The residual water remaining in the drain line (24) and the water reservoir (25) from the previous washing program, after the drain pump (9) is switched off, presses the buoyancy body (23) into a sealing arrangement (not shown) in the tub opening. As a result, no detergent can get into the drain unused, so that smaller amounts of detergent can be dosed.

Bei der Regeneration des Enthärters (4) wird in der Anordnung der Fig. 2 die notwendige Wassermenge zum Regenerieren durch zeitliche Ansteuerung eines Magnetvenails (1) Ober eine Leitung (29) zur Verfügung gestellt Über die Wasserkammer (3) wird das Wasser über die Leitung (15) gegebenenfalls über ein ebenfalls vorgesehenes Ventil (20) (hier nicht gezeigt) in das Satzgefäß (5) gecfrückt Von dort gelangt die Salzsote dann in den Enthärter (4).During the regeneration of the softener (4) in the arrangement of FIG. 2, the amount of water required for regeneration is made available by a magnetic valve (1) being activated via a line (29) (15) optionally crimped into the set container (5) via a valve (20) (not shown here), which is also provided. From there, the brine then reaches the softener (4).

Nach erfolgter Regeneration des Enthärters (4) wird die Regeneratinslösung durch einen emeuten Wasserstoß Ober die Verbindungsleitung (13) zur Ablaufpumpe (9) geleilet Dabei ist das Ventil (27) geöffnet und das Ventil (26) geschlossen. In vorteilhafter Ausbildung wird das Ventii - (27) gleichzeitig mit der Ablaufpumpe (9) eingeschaltet, so daß die aus dem Enthärter (4) ausgespülte Regeneratinonsiösung sofort über den Ablauf (28) aus der Maschine herausbefördert wird.After regeneration of the softener (4), the regeneration solution is passed through the water line via the connecting line (13) to the drain pump (9). The valve (27) is open and the valve (26) is closed. In an advantageous embodiment, the valve (27) is switched on simultaneously with the drain pump (9), so that the regeneration solution rinsed out of the softener (4) is immediately conveyed out of the machine via the drain (28).

Anstelle des Ventils (26) kann das Ventil (27) auch als 3-Wege-Ventil ausgeführt sein, um entweder die Leitung - (13) oder die Leitung (11) zu öffnen oder zu schließen. Diese Ausbildung erfüllt denselben Zweck, wie die gezeigte Anordnung nach Fig. 2.Instead of the valve (26), the valve (27) can also be designed as a 3-way valve in order to either open or close the line - (13) or line (11). This design serves the same purpose as the arrangement shown in FIG. 2.
