- the invention according to claim 1 consists in that, since each program of the washing machine is preceded by a pumping process or each program is started first with a pumping process, the residual water in the tub is conveyed into the drain hose of the drain system before the fresh water supply and detergent flushing is started. Because of the hydrostatic water pressure then present in the drain hose of the drain system, which is enlarged in volume, the tub valve device is brought into its sealing, closed position in the drain port and is also held. This ensures, without manual intervention, that at the time of washing in or other laundry treatment agents, the valve device is pressed into its position preventing detergents from penetrating into the drain system.
- the drain pump is switched on before the start of each laundry treatment program via the machine-side program switching mechanism, the control disk of which controls the drain pump or emptying pump is designed accordingly.
- the duration of the start-up of the drain pump is coordinated so that the residual or collected water pumped out of the drain container can only be pumped with certainty into the liquid collection space formed in the drain hose and is not funded into the sewage network.
- the enlarged receiving volume of the drain hose or a corresponding storage or additional container for the residual or collecting water is provided at the highest point of the drain hose in order to ensure a corresponding hydrostatic water pressure for tightly closing the valve device.
- the valve device is formed from an elastic flap valve known per se, which is held on a valve support plate with a flow opening centered in the bellows-like outlet connection.

- the valve flap 15 is pressed against its valve seat by the hydrostatic water pressure and the flow opening 17 in the valve support plate 12 is closed.
- the detergent washed into the tub 5 from the detergent dispenser 2 thus remains in the tub 5 and cannot settle into the drain system of the washing machine. It is particularly expedient to first briefly start up the drain pump 8 before the fresh water supply into the tub 5 begins.
- the duration of the start-up of the drain pump 8 is chosen so that the residual water to be pumped out of the drain container is pumped into the collecting space or additional container 10 provided in the drain hose 9 at its highest point.
- the brief activation of the drain pump 8 before the start of each laundry treatment program takes place via the machine-side program switching mechanism.
Description
Die Erfindung betrifft eine Trommelwaschmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a drum washing machine according to the preamble of claim 1.
Bei den bisher bekannten Waschmaschinen stellt sich nach wie vor das Problem, eine bessere Ausnutzung der eingesetzten Wasch- und Spülmittel zu erzielen. Ein erheblicher Waschmittelverlust kann insbesondere dadurch hervorgerufen werden, daß sich das eingespülte Waschmittel im Ablaufsystem der Maschine absetzt und mit dem Waschmittel im nachfolgenden Abpumpvorgang ungenutzt abfließt. Um dieser nachteiligen Erscheinung entgegenzuwirken, sind bereits zahlreiche Vorschläge bekanntgeworden, die aber entweder nicht zu dem erwünschten Erfolg führten oder wegen ihres technischen Aufwandes in der Praxis nicht realisierbar waren.With the washing machines known to date, the problem still arises of achieving better utilization of the detergents and washing-up agents used. A considerable loss of detergent can be caused, in particular, by the fact that the detergent which has been flushed in settles in the drain system of the machine and flows off unused with the detergent in the subsequent pumping process. In order to counteract this disadvantageous phenomenon, numerous proposals have already become known, which either did not lead to the desired success or were not feasible in practice due to their technical complexity.
So ist bei einer aus der DE-U-78 13 695 bekannten Waschmaschine der in Rede stehenden Art im balgartigen Ablaufstutzen des Laugenbehälters eine Dichtungsventileinrichtung aus einer Kunststoff-Hohlkugel angeordnet, durch die der Durchfluß der Waschlauge zur Laugenpumpe hin entweder gesperrt oder freigegeben wird. Die Laugenpumpe ist über eine zusätzliche Speiseleitung mit dem Frischwasserzulauf in Verbindung gebracht. Nach Öffnen des Frischwasserzulaufs gelangt das einlaufende Frischwasser hier zunächst nicht in den Waschmitteleinspülkasten der Waschmaschine sondern wird über die Speiseleitung direkt in den balgartigen Ablaufstutzen des Ablaufsystems geleitet. Wenn Frischwasser in genügender Menge in den balgartigen Ablaufstutzen eingelaufen ist, wird die Kunststoff-Hohlkugel der Dichtungsventileinrichtung in ihre Dichtposition gebracht und durch den im Ablaufsystem vorhandenen hydrostatischen Wasserdruck in dieser Position gehalten.Thus, in a washing machine of the type in question known from DE-U-78 13 695, a sealing valve device made of a hollow plastic ball is arranged in the bellows-like drain socket of the tub, through which the flow of the washing liquor to the tub pump is either blocked or released. The drain pump is connected to the fresh water supply via an additional feed line. After opening the fresh water inlet, the incoming fresh water does not get into the detergent dispenser box of the washing machine, but is fed via the feed line directly into the bellows-shaped drain socket of the drain system. If fresh water The plastic hollow ball of the sealing valve device is brought into its sealing position and is held in this position by the hydrostatic water pressure in the drainage system.
Der Eintritt von Wasser aus dem Laugenbehälter in das Ablaufsystem der Waschmaschine ist somit verhindert. Nunmehr erst wird das Frischwasser in den Waschmitteleinspülkasten geleitet und mit diesem das Behandlungsmittel bzw. Waschmittel ausgespült und dem Laugenbehälter zugeführt. Durch den auf diese Weise verschlossenen Laugenbehälter-Ablaufstutzen wird dafür gesorgt, daß während des Waschmitteleinspülvorganges kein Wasch- bzw. Behandlungsmittel in das Ablaufsystem gelangen kann, wo es für den folgenden Waschvorgang dann verloren wäre. Wegen der Größe der von der Ventileinrichtung im Ablaufstutzen zu verschließenden Laugendurchflußöffnung und der Einfachheit des zur Verwendung gelangenden Ventils sowie der nicht zu unterschätzenden Möglichkeit der Verschmutzung des Ventildichtsitzes durch Ablagerungen von Waschmittel oder auch Wäscheflusen kann nicht sichergestellt werden, daß die dem Ventilverschluß dienende Wassersäule im Ablaufschlauch bei längerer Betriebsstillstandszeit infolge Ventilundichtigkeiten in den Laugenbehälter zurückläuft. Der Vorteil der Vermeidung von Waschmittelverlusten wäre dann nicht mehr gegeben.The entry of water from the tub into the drain system of the washing machine is thus prevented. Only now is the fresh water directed into the detergent dispenser drawer, with which the treatment agent or detergent is rinsed out and fed to the tub. The suds container drain neck which is closed in this way ensures that no detergent or treatment agent can get into the drain system during the detergent dispensing process, where it would then be lost for the subsequent washing process. Because of the size of the liquor flow opening to be closed by the valve device in the drain connection and the simplicity of the valve used, and the possibility of contamination of the valve sealing seat due to deposits of detergent or laundry fluff, which cannot be underestimated, it cannot be ensured that the water column serving the valve closure in the drain hose runs back into the tub for longer periods of inactivity due to valve leaks. The advantage of avoiding loss of detergent would then no longer exist.
Der Erfindung liegt nun die Aufgabe zugrunde, durch einfache Maßnahmen sicherzustellen, daß die im Ablaufsystem der Waschmaschine angeordnete Dichtungs-Ventileinrichtung vor Anlauf bzw. vor Beginn eines Wasch- bzw. Reinigungsprogrammes automatisch und damit immer zuverlässig in ihre das Ablaufsystem der Waschmaschine verschließende Stellung gebracht wird.The invention is based on the object to ensure by simple measures that the sealing valve device arranged in the drain system of the washing machine is automatically and thus always reliably brought into its position closing the drain system of the washing machine before starting or before the start of a washing or cleaning program .
Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved according to the invention by the characterizing features of claim 1.
Es ist zwar bei einer programmgesteuerten Waschmaschine bekannt (DE-A-2 818 464), über deren Programmsteuereinrichtung vor dem Öffnen eines Ventils für die Frischwasserzufuhr kurzzeitig die Entleerungspumpe einzuschalten. Diese Maschine hat jedoch keine Richtungsventilanordnung im Ablaufstutzen der lange. Durch das Einschalten du Entleerungspumpe soll aber anstehendes Restwasser aus dem Ablaufsystem abgepumpt und die mit dem Ablaufsystem verbundene Niveauregeleinrichtung, bestehend aus Druckwächter mit Luftfalle, vom Restwasser befreit und gleichzeitig entlüftet werden. Durch eine solche Maßnahme wird bei dieser bekannten Waschmaschine verhindert, daß der am Ablaufsystem der Waschmaschine angeschlossene Druckwächter bei der Frischwasserzufuhr eine falsche Anzeige liefert und ein exaktes Abschalten des Wasserzulaufs bei einem gewünschten Niveau sicherstellt. Nach Abschalten der Entleerungspumpe läuft das im Ablaufschlauch befindliche Restwasser wieder in den tiefer liegenden Bereich des Ablaufsystems zurück und verhindert, daß mit dem Frischwasser eingespülte Wäschebehandlungsmittel in das vorher teilweise oder völlig entleerte Ablaufsystem geschwemmt werden.It is known in a program-controlled washing machine (DE-A-2 818 464), via its program control device before opening a valve for the fresh water supply to briefly switch on the drain pump. However, this machine does not have a directional valve arrangement in the drain port of the long. By switching on the drain pump, any residual water present is to be pumped out of the drain system and the level control device, consisting of a pressure switch with air trap, connected to the drain system is to be freed of residual water and vented at the same time. Such a measure prevents in this known washing machine that the pressure switch connected to the drain system of the washing machine supplies an incorrect display when the fresh water is supplied and ensures that the water supply is shut off precisely at a desired level. After the emptying pump has been switched off, the residual water in the drain hose runs back into the lower area of the drain system and prevents washing agent washed in with the fresh water from being washed into the previously partially or completely emptied drain system.
Demgegenüber besteht die Erfindung nach Anspruch 1 darin, daß, da jedem Programm der Waschmaschine ein Abpumpvorgang vorgeschaltet bzw. jedes Programm zuerst mit einem Abpumpvorgang begonnen wird, das im Laugenbehälter befindliche Restwasser vor Beginn der Frischwasserzuführung und der Waschmitteleinspülung in den Ablaufschlauch des Ablaufsystems gefördert wird. Aufgrund des dann im volumenmäßig vergrößerten Ablaufschlauch des Ablaufsystems anstehenden hydrostatischen Wasserdrucks wird die Laugenbehälter-Ventileinrichtung in ihre dichtende Schließposition im Ablaufstutzen gebracht und auch gehalten. Damit ist ohne manuelles Zutun sichergestellt, daß zum Zeitpunkt des Einspülens von Wasch- oder sonstigen Wäschebehandlungsmitteln die Ventileinrichtung in ihre ein Eindringen von Waschmitteln in das Ablaufsystem verhindernde Stellung festgedrückt ist.In contrast, the invention according to claim 1 consists in that, since each program of the washing machine is preceded by a pumping process or each program is started first with a pumping process, the residual water in the tub is conveyed into the drain hose of the drain system before the fresh water supply and detergent flushing is started. Because of the hydrostatic water pressure then present in the drain hose of the drain system, which is enlarged in volume, the tub valve device is brought into its sealing, closed position in the drain port and is also held. This ensures, without manual intervention, that at the time of washing in or other laundry treatment agents, the valve device is pressed into its position preventing detergents from penetrating into the drain system.
Das Einschalten der Laugenpumpe vor Beginn eines jeden Wäschebehandlungsprogrammes erfolgt über das maschinenseitige Programmschaltwerk, dessen die Laugenpumpe bzw. Entleerungspumpe steuernde Steuerscheibe dafür entsprechend ausgelegt ist. Die Dauer des Inbetriebsetzens der Laugenpumpe ist dabei so abgestimmt, daß das aus dem Laugenbehälter abgepumpte Rest- oder Sammelwasser mit Sicherheit nur bis in den im Ablaufschlauch gebildeten Flüssigkeits-Sammelraum gepumpt und nicht in das Abwassernetz gefördert wird. Das vergrößerte Aufnahmevolumen des Ablaufschlauches bzw. eines entsprechenden Vorratsoder Zusatzbehälters für das Rest- oder Sammelwasser ist dabei an der höchsten Stelle des Ablaufschlauches vorgesehen, um einen entsprechenden hydrostatischen Wasserdruck zum dichten Schließen der Ventileinrichtung sicherzustellen.The drain pump is switched on before the start of each laundry treatment program via the machine-side program switching mechanism, the control disk of which controls the drain pump or emptying pump is designed accordingly. The duration of the start-up of the drain pump is coordinated so that the residual or collected water pumped out of the drain container can only be pumped with certainty into the liquid collection space formed in the drain hose and is not funded into the sewage network. The enlarged receiving volume of the drain hose or a corresponding storage or additional container for the residual or collecting water is provided at the highest point of the drain hose in order to ensure a corresponding hydrostatic water pressure for tightly closing the valve device.
In Weiterbildung der Erfindung ist die Ventileinrichtung aus einem an sich bekannten elastischen Klappenventil gebildet, das an einer im balgartigen Ablaufstutzen zentrierten Ventilträgerplatte mit Durchflußöffnung gehaltert ist. Im elastischen Klappenventil ist eine Schlitzöffnung ausgebildet, mit der das Klappenventil an einem an der Ventilsitzseite der Ventilträgerplatte angeformten bzw. ausgeformten Pilz durch Auf- bzw. Anknöpfen befestigbar ist. Durch diese Maßnahmen wird die Montage und das Auswechseln des Klappenventils im Kundendienstfall erheblich erleichtert.In a further development of the invention, the valve device is formed from an elastic flap valve known per se, which is held on a valve support plate with a flow opening centered in the bellows-like outlet connection. A slot opening is formed in the elastic flap valve, by means of which the flap valve can be attached to a mushroom molded or molded on the valve seat side of the valve carrier plate by buttoning it on or off. These measures make installation and replacement of the flap valve in customer service considerably easier.

Die Trommelwaschmaschine 1 besitzt in ihrem oberen Bereich einen Waschmitteleinspülkasten 2 bekannter Bauart für die Aufnahme pulverförmiger und/oder flüssiger Behandlungsmittel. Eine Frischwasserzuleitung 3 zum Waschmitteleinspülkasten 2 wird in üblicher Weise von einem nicht dargestellten Magnetventil programmabhängig gesteuert. Die Wäschetrommel 4 der Trommelwaschmaschine 1 ist in einem Laugenbehälter 5 umlaufend angeordnet. Der Laugenbehälter 5 besitzt bodenseitig einen balgartigen flexiblen Ablaufstutzen 6, an dem eine Entlüftungsleitung 7 angeschlossen ist. Der balgartige Ablaufstutzen 6 stellt eine Verbindung zu einer das Entleeren des Laugenbehälters 5 bewirkenden Laugenpumpe 8 her, an der ein Ablaufschlauch 9 angebracht ist. Im Ablaufschlauch 9 ist zweckmäßig ein kleiner Zusatzbehälter 10 zur Vergrößerung von dessen Volumen angeordnet bzw. gebildet. Der balgartige Ablaufstutzen 6 ist mit einer Ventileinrichtung ausgerüstet, die zweckmäßig als Klappenventil 11 ausgebildet ist, dessen Einzelheiten in den Fig. 2 bis 6 näher dargestellt sind.
Diese Klappenventileinrichtung soll verhindern, daß mit Einspülen des Waschmittels aus dem Waschmitteleinspülkasten 2 Waschmittel in das beschriebene Ablaufsystem der Trommelwaschmaschine gelangen können, von wo sie für den Waschvorgang dann ungenutzt in das Abwassernetz gefördert werden.The drum washing machine 1 has in its upper area a

Die vorgenannte Klappenventileinrichtung 11 im balgartigen Ablaufstutzen 6 besteht aus einer in den Ablaufstutzen 6 einsetzbaren und dort zentrierten Ventilträgerplatte 12, deren Unterseite 13, die der Laugenpumpe 8 zugerichtet ist, einen angeformten Pilz 14 zum Aufknöpfen einer aus elastischem Material, z. B. Gummi, bestehenden Ventilklappe 15 trägt. Die Ventilklappe 15 ist zu diesem Zweck mit einer Schlitzöffnung 16 versehen und deckt in Anlage mit der Unterseite 13 der Ventilträgerplatte 12 eine in dieser gebildete Durchflußöffnung 17 dicht ab. An der Oberseite 18 der Ventilrägerplatte 12 sind zwei nebeneinanderliegende Zapfen 19, 19' angeformt.The aforesaid
Es wäre auch denkbar, die Klappenventileinrichtung 11, 16 als aus- bzw. angeformten Bestandteil des balgartigen Ablaufstutzens 6 auszubilden.It would also be conceivable to design the
Die Klappenventileinrichtung 11 zur Verhinderung des Waschmittelaustrittes bzw. -verlustes aus dem Laugenbehälter 5 arbeitet in der Weise, daß die Entleerungs- bzw. Laugenpumpe 8 so gesteuert wird, daß nach deren Abschalten das Niveau h2 sowohl im entsprechend dimensionierten Ablaufschlauch 9 als auch in der Entlüftungsleitung 7 mit ausreichender Sicherheit immer höher liegt als das höchste Niveau h1 bei irgendeinem Waschprogramm der Maschine, d. h. h2 muß immer größer als h1 sein. Damit wird die Ventilklappe 15 durch den anstehenden hydrostatischen Wasserdruck gegen ihren Ventilsitz gepreßt und die Durchflußöffnung 17 in der Ventilträgerplatte 12 geschlossen. Das aus dem Waschmitteleinspülkasten 2 in den Laugenbehälter 5 eingespülte Waschmittel verbleibt somit im Laugenbehälter 5 und kann sich nicht in das Ablaufsystem der Waschmaschine absetzen. Als besonders zweckmäßig ist es dabei, vor Beginn der Frischwasserzufuhr in den Laugenbehälter 5 zuerst die Laugenpumpe 8 kurzzeitig in Betrieb zu setzen. Die Dauer des Inbetriebsetzens der Laugenpumpe 8 wird dabei so gewählt, daß das aus dem Laugenbehälter abzupumpende Restwasser m[t Sicherheit in den im Ablaufschlauch 9 an dessen höchster Stelle vorgesehenen Sammelraum bzw. Zusatzbehälter 10 gepumpt wird. Das kurzzeitige Einschalten der Laugenpumpe 8 vor Beginn eines jeden Wäschebehandlungsprogrammes erfolgt dabei über das maschinenseitige Programmschaltwerk.The
