Die vorliegende Erfindung betrifft das Gebiet der Waschmaschinen, die einen Waschbottich umfassen, der mit Waschwasser zu füllen ist und eine Ablauföffnung, eine Ablaufpumpe, eine Ablaufleitung, die den Bottich wassermäßig mit der Ablaufpumpe verbindet und einen Ventilteil aufweist, der dicht mit dem Bottich verbunden ist, sowie einen Rohrteil aufweist, der wassermäßig mit der Ablaufpumpe verbunden ist; wobei die Waschmaschine weiter ein im Waschwasser schwimmfähiges Ablaufventil umfasst, das beweglich im Inneren des Ventilteils angeordnet ist, um die Ablauföffnung zu verschließen, wenn sich Waschwasser im Inneren des Bottichs befindet und die Ablaufpumpe in Ruhe ist, oder um die Ablauföffnung zu öffnen, wenn sich kein Waschwasser im Inneren des Bottichs befindet oder die Ablaufpumpe in Betrieb ist.The present invention relates to the field of washing machines comprising a washing tub to be filled with washing water and a drain port, a drain pump, a drain line which watertably connects the tub to the drain pump and has a valve member which is sealed to the tub , and a pipe part, which is watertermally connected to the drain pump; wherein the washing machine further comprises a drain valve floatable in the washing water, which is movably disposed inside the valve member to close the drain hole when wash water is inside the tub and the drain pump is at rest or to open the drain hole when there is no wash water inside the tub or the drain pump is in operation.
Stand der Technik Das Patent DE 4442089 A1 beschreibt eine Waschmaschine, die einenPRIOR ART The patent DE 4442089 A1 describes a washing machine which has a
Waschbottich aufweist, in dem eine Trommel angeordnet ist, die sich im Inneren drehen kann und in welche die zu waschenden Kleidungsstücke gelegt werden.Has a washing tub in which a drum is arranged, which can rotate inside and in which the clothes to be washed are placed.
Der Waschbottich weist in seinem oberen Teil eine Waschwasser- Einlaufanschluss auf, um den Waschbottich zum Waschen und Spülen der zu waschenden Materialien teilweise zu füllen. Im unteren Teil des Tanks ist eine Ablauföffnung angeordnet, an die am äußeren Teil des Waschbottichs eine Ablaufleitung angeschlossen ist, die den Waschbottich mit der Ablaufpumpe verbindet, um das Waschwasser aus dem Waschbottich zu entleeren, wenn es der Waschvorgang erfordert. Zum Abschluss des Waschvorgangs stößt die Ablaufpumpe das gesamte Wasser aus dem Inneren des Bottichs und der Ablaufleitung aus, weshalb am Beginn des folgenden Zyklus das in den Waschbottich eingeflossene Wasser die Ablaufleitung füllt und nicht am Waschvorgang teilnimmt. Um zu vermeiden, dass das in den Bottich für den Waschvorgang eingebrachte Waschmittel in die Ablaufleitung gelangt, weist diese einen Ventilteil auf, in dem sich ein schwimmfähiges Ventil in Form einer Hohlkugel befindet, die sich in die Ablauföffnung einpasst, wenn genügend Wasser für den Beginn des Zyklus eingeströmt ist. Auf diese Weise entweicht das Waschmittel nicht durch die Ablaufleitung, wodurch Umweltschäden vermieden werden. Der Ventilteil der Ablaufleitung ist ein flexibles Teil mit ziemlich komplexer Form, das auf dichte Weise mittels eines beliebigen Systems in Art eines Flansches am Waschbottich befestigt sein muss. Das Patent DE 3624065 A1 beschreibt eine Waschmaschine ähnlich der vorhergehenden, die eine Ablaufleitung ähnlich derjenigen der vorhergehenden Maschine mit einem Ventilteil aufweist, der auf dichte Weise mit dem Waschbottich mittels eines Flansches verbunden ist. Das Ventil befindet sich im Inneren des Ventilteils und ist als Klappe oder Zunge ausgeführt, die aus einem Stück mit der Wand der Ablaufleitung verbunden ist, genauer mit der Wand des Ventilteils. Der Ventilteil und das Ventil sind aus einem komplexen Teil aus flexiblen Material hergestellt. Wenn sich kein Wasser im Inneren der Ablaufleitung befindet oder die Pumpe in Betrieb ist, senkt sich das Ventil und erlaubt die Verbindung zwischen dem Inneren des Bottichs und der Ablaufleitung. Ähnlich wie beim Vorgang der vorhergehenden Maschine füllt sich, wenn der Waschzyklus beginnt, die Ablaufleitung mit Wasser, und das Wasser selbst bringt das Ventil zum Schwimmen und drückt es gegen die Ablauföffnung des Waschbottichs.The washing tub has in its upper part a wash water inlet port to partially fill the washing tub for washing and rinsing the materials to be washed. In the lower part of the tank a drain opening is arranged, to the outer part of the washing tub, a drain line is connected, which connects the washing tub with the drain pump to empty the washing water from the washing tub, if it requires the washing process. At the completion of the washing operation, the drain pump discharges all the water from the inside of the tub and the drain pipe, therefore, at the beginning of the following cycle, the water poured into the washing tub fills the drain pipe and does not participate in the washing operation. In order to avoid that the introduced into the tub for washing detergent enters the drain line, this has a valve member in which there is a buoyant valve in the form of a hollow ball, which fits into the drain opening, if enough water for the beginning of the cycle has flowed. In this way, the detergent does not escape through the drain line, thereby avoiding environmental damage. The valve member of the drain line is a flexible part of rather complex shape, which must be tightly fastened to the wash tub by any system, such as a flange. The patent DE 3624065 A1 describes a washing machine similar to the preceding, which has a drain line similar to that of the previous machine with a valve member which is connected in a sealed manner with the washing tub by means of a flange. The valve is located inside the valve part and is designed as a flap or tongue, which is connected in one piece with the wall of the drain line, more precisely with the wall of the valve part. The valve part and the valve are made of a complex part of flexible material. If there is no water inside the drain line or the pump is operating, the valve lowers and allows communication between the interior of the tub and the drain line. Similar to the process of the previous machine, when the washing cycle starts, the drain line fills with water, and the water itself makes the valve float and pushes it against the drain opening of the washing tub.
Beide Konfigurationen einer Waschmaschine weisen eine komplexe Ablaufleitung auf, weshalb Dichtigkeitsprobleme hervorgerufen werden können. Aufgabe der ErfindungBoth configurations of a washing machine have a complex drain line, which can cause leakage problems. Object of the invention
Es ist die Aufgabe der Erfindung, eine Waschmaschine mit einer vereinfachten, dichten und leicht am Waschbottich der Waschmaschine zu montierenden Ablaufleitung zu schaffen.It is the object of the invention to provide a washing machine with a simplified, dense and easy to be mounted on the washing tub of the washing machine drain line.
Diese Aufgabe wird mittels einer Waschmaschine gelöst, die einen Waschbottich umfasst, der mit Waschwasser zu füllen ist und eine Ablauföffnung, eine Ablaufpumpe, eine Ablaufleitung, die den Waschbottich wassermäßig mit der Ablaufpumpe verbindet und einen Ventilteil aufweist, der dicht mit dem Waschbottich verbunden ist, sowie einen Rohrteil aufweist, der wassermäßig mit der Ablaufpumpe verbunden ist; sowie ein Ablaufventil, das im Waschwasser schwimmfähig ist und beweglich im Inneren des Ventilteils angeordnet ist, um die Ablauföffnung zu verschließen, wenn sichThis object is achieved by means of a washing machine comprising a washing tub which is to be filled with washing water and a drain opening, a drain pump, a drain line which connects the washing tub to the drainage pump in water and has a valve part tightly connected to the washing tub. and a pipe part which is watertermally connected to the drain pump; and a drain valve floatable in the wash water and movably disposed inside the valve member to close the drain hole when
Waschwasser im Inneren des Waschbottichs befindet und die Ablaufpumpe in Ruhe ist, oder um die Ablauföffnung zu öffnen, wenn sich kein Waschwasser im Inneren desWash water is inside the wash tub and the drain pump is at rest, or to open the drain hole when no wash water inside the
Waschbottichs befindet oder die Ablaufpumpe in Betrieb ist, wobei der Ventilteil in einem Stück mit dem Waschbottich ausgebildet ist und der Rohrteil mit einem Austrittsanschluss des Ventilteils verbunden ist.Washer is located or the drain pump is in operation, the valve part in a piece with the washing tub is formed and the pipe part is connected to an outlet port of the valve member.
Auf diese Weise enthält der Waschbottich neben der Ablauföffnung den Ventilteil aus einem Stück, weshalb die Dichtigkeit immer besser ist, da Verbindungen zwischen beiden Teilen vermieden werden. Die Ablaufleitung vereinfacht sich, da beim Einbeziehen in einem Stück in den Waschbottich nur der Rohrteil mit dem Austrittsanschluss des Ventilteils verbunden werden muss. Insbesondere kann der Rohrteil ein zylindrisches Normrohr sein, das mittels herkömmlicher Flansche in den Austrittsanschluss und in die Ablaufpumpe eingeschoben wird. Die Waschmaschine kann ein Frontlader oder ein Toplader sein; sie kann imIn this way, the washing tub in addition to the drain opening, the valve member in one piece, which is why the tightness is always better, since connections between the two parts are avoided. The drain line simplifies, since only one part of the pipe has to be connected to the outlet connection of the valve part when it is integrated into the washing tub in one piece. In particular, the pipe part may be a cylindrical standard pipe which is inserted by means of conventional flanges into the outlet connection and into the drainage pump. The washing machine may be a front loader or a top loader; she can in
Inneren des Waschbottichs eine Trommel mit horizontaler Rotation oder eine Trommel mit vertikaler Rotation aufweisen.Inside the wash tub have a drum with horizontal rotation or a drum with vertical rotation.
Der Ventilteil ist als Bestandteil des Bottichs ausgeführt und weist einen Innenraum auf, der mit dem Inneren des Waschbottichs über die Ablauföffnung verbunden ist. Bestandteil bedeutet, dass er kein Teil ist, das demontiert und wieder montiert werden kann. Die Ablauföffnung ist mittels des im Waschwasser schwimmfähigen Ventils verschließbar. Der Innenraum des Ventilteils weist einen Austrittsanschluss auf, an den der Rohrteil angeschlossen wird. Das schwimmfähige Ventil kann als ein Element mit niedrigerer Dichte als das Waschwasser ausgeführt sein, mit einer solchen Form, dass es sich in die Ablauföffnung einpasst. Es ist besonders vorteilhaft, dass die Ablauföffnung kreisförmig ist, da das Ventil eine Kugelform oder teilweise Kugelform aufweisen kann, die sich darin einpasst und den Durchfluss des Waschwassers versperrt. Es ist notwendig, dass das Innere des Ventilteils eine solche Form aufweist, welche die Bewegung des Ventils in ihrem Inneren auf unbeabsichtigte Weise erlaubt und dabei verschlossen bleibt. Die Funktionsweise des Ventils während des Waschvorgangs ist gleich derjenigen nach dem Stand der Technik, indem es die Ablauföffnung verschlossen hält, während Wasser im Ventilteil vorhanden ist, um das Ventil gegen die Öffnung zu drücken.The valve member is designed as part of the tub and has an inner space which is connected to the interior of the washing tub via the drain opening. Component means that it is not a part that can be dismantled and reassembled. The drain opening can be closed by means of the valve floatable in the wash water. The interior of the valve member has an outlet port to which the pipe part is connected. The buoyant valve may be embodied as a lower density member than the washing water having a shape to fit in the drainage hole. It is particularly advantageous that the discharge opening is circular, since the valve may have a spherical shape or a partial spherical shape, which fits therein and blocks the flow of washing water. It is necessary that the interior of the valve member has such a shape as to allow the movement of the valve in its interior inadvertently while remaining closed. The operation of the valve during the washing process is similar to that of the prior art, by keeping the drainage opening closed while there is water in the valve member to urge the valve against the opening.
In einer bevorzugten Ausführungsform ist der Bottich aus zwei Bottich- Teilstücken aus Kunststoff ausgeführt. Jedes der Bottich-Teilstücke weist einen Teil des Ventilteils auf, der in einem Stück mit dem entsprechenden Teilstück gespritzt wurde. Vorzugsweise werden sie mittels Kunststoffschweißtechnik verbunden, wenn auch nicht notwendigerweise, da sie verklebt oder verklammert werden können. Die Ablauföffnung ist in einem ersten Bottich-Teilstück ausgeführt, und so, bei der Ausführung aus einem Spritzgussteil, wird verhindert, dass sein Rand Grate aufweist, die ein korrektes Schließen des Ventils stören könnten.In a preferred embodiment, the tub is made of two tub sections made of plastic. Each of the tub sections has a portion of the valve member that has been molded in one piece with the corresponding section. Preferably, they are joined by means of plastic welding technology, although not necessarily, since they can be glued or clamped. The Drain port is embodied in a first tub section, and thus, in the embodiment of an injection molded part, prevents its edge has burrs that could interfere with a proper closing of the valve.
In einer besonderen Ausführungsform des Ventils ist vorgesehen, dass es die Form einer Klappe aufweist. Bei einer solchen Geometrie wird weniger Raum imIn a particular embodiment of the valve is provided that it has the shape of a flap. With such a geometry, less space is needed

Stopfenteil auf, der sich in die Ablauföffnung einpasst, einen Schwimmerteil sowie einStopper part, which fits into the drain hole, a float part and a
Scharnierelement, das mit dem Ventilteil verbunden ist, um die Drehung desHinge element, which is connected to the valve member to prevent the rotation of the
Ablaufventils zwischen der geöffneten und der geschlossenen Position zu erlauben. Bei dieser Konfiguration wird die Bewegung des Ventils im Inneren des Ventilteils begrenzt und das Verschlusssystem besser kontrolliert.Allow drain valve between the open and the closed position. In this configuration, the movement of the valve inside the valve member is limited and the closure system is better controlled.
Und um sie noch mehr zu begrenzen, weist das Ablaufventil einen Anschlag auf, der die Drehung des Ablaufventils in der offenen Stellung begrenzt und verhindert, dass es an der Wand des Ventilteils haften bleibt. Um zu verhindern, dass der Schwimmerteil überflutet wird, wodurch dasAnd to further limit it, the drain valve has a stop that limits the rotation of the drain valve in the open position and prevents it from sticking to the wall of the valve member. To prevent the float part from being flooded, causing the float to flounder
Aufschwimmen des Ablaufventils und damit seine Funktion unmöglich gemacht würde, begrenzt der Anschlag die Drehung des Ablaufventils in der geöffneten Stellung auf eine Öffnung zwischen 15° und 35°, vorzugsweise zwischen 20° und 30°, vorteilhafterweise 25°. Das Scharnierelement ist als eine Rippe ausgeführt, die in eine Aussparung des ersten Bottich-Teilstücks eingefügt ist. Dies ist eine einfach auszuführende Montage, die außerdem die korrekte Position mittels eines Schiebers sichert, der sich in die Aussparung einpasst und seine Verschiebung in der Aussparung begrenzt. Und um zu verhindern, dass er sich in der Aussparung verschiebt, drückt das zweite Bottich- Teilstück auf das Scharnierelement in der Aussparung des ersten Teilstücks des Bottichs, wenn die beiden Teilstücke vereinigt sind.Floating the drain valve and thus its function would be impossible, the stop limits the rotation of the drain valve in the open position to an opening between 15 ° and 35 °, preferably between 20 ° and 30 °, advantageously 25 °. The hinge member is designed as a rib which is inserted into a recess of the first tub section. This is an easy-to-install assembly that also secures the correct position by means of a slide that fits into the recess and limits its displacement in the recess. And to prevent it from shifting in the recess, the second tub section presses on the hinge member in the recess of the first section of the tub when the two sections are unified.
Um besseren Kontakt mit der Ablauföffnung zu machen, ist das Ablaufventil aus elastischem Material ausgeführt. Auf diese Weise ist dies vor allem bei dem Ablaufventiltyp in Klappenform, der einen Scharnierteil aufweist, vorteilhaft, um das Biegen dieses Teils zu unterstützen, da es vorzugsweise aus einem Stück ausgeführt ist und sich im Bereich des Scharniers unter dem Eigengewicht des Stopfenteils und des Schwimmerteils biegen muss. In dem Falle, dass es ein Ventil in Form einer Hohlkugel ist, ist es nicht notwendig, dass es flexibel ist, jedoch, dass es eine glatte Oberfläche aufweist, um sich an die Ablauföffnung anzupassen. Es ist auch vorteilhaft, dass das Ablaufventil zumindest im Stopfenteil eine Anti-Haft-Oberfläche aufweist, um die Möglichkeit zu reduzieren, dass sich Waschmittelreste, Fäden oder andere Elemente anheften, die das Schließen verschlechtern könnten. Es ist vorteilhaft, dass die Ablauföffnung eine Kreisform und der Stopfenteil teilweise eine Kugelform aufweist, die sich in die Ablauföffnung einpasst. Die Form des Stopfenteils ist nicht notwendigerweise teilweise kugelförmig, da auch eine Kegelform dieselbe Funktion ausüben kann.To make better contact with the drain opening, the drain valve is made of elastic material. In this way, this is particularly advantageous in the valve-type drain valve type, which has a hinge part, to assist in bending this part, as it is preferably made in one piece and below the weight of the plug part and the float part in the region of the hinge must bend. In the case that it is a valve in the form of a hollow sphere, it is not necessary that it is flexible, but that it is a smooth Has surface to adapt to the drain opening. It is also advantageous that the drain valve has an anti-stick surface, at least in the plug part, to reduce the possibility of sticking detergent residues, filaments or other elements that could worsen closure. It is advantageous that the drain opening has a circular shape and the plug part partially has a spherical shape, which fits into the drain opening. The shape of the plug part is not necessarily partly spherical, since a cone shape can also perform the same function.
Es ist vorgesehen, dass der Schwimmerteil eine zylindrische Hohlform aufweist mit einem Ende, das mit dem Stopfenteil verbunden ist, und dass sein anderes Ende offen ist, wo die Luft eintreten kann, wenn der Wasserspiegel im Ventilteil ansteigt, und das Aufschwimmen des Ventils unterstützt. Er kann auch hermetisch verschlossen sein, damit die Luft im Inneren das Ventil zum Schwimmen bringt.It is envisaged that the float part has a cylindrical hollow shape with one end connected to the plug part, and that its other end is open, where the air can enter, when the water level in the valve part rises, and supports the floating of the valve. It can also be hermetically sealed so that the air inside makes the valve swim.
