Description

Die Erfindung betrifft ein wasserführendes Haushaltsgerät, insbesondere eine Geschirrspül- oder Waschmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a water-bearing household appliance, in particular a dishwasher or washing machine according to the preamble of claim 1.

Wasserführende Haushaltsgeräte, wie beispielsweise Geschirrspülmaschinen, weisen ein Leitungssystem auf, das es erlaubt, Spülflotte nach Beendigung eines Reinigungsvorganges aus dem wasserführenden Haushaltsgerät in ein hausseitiges Abwasserentsorgungssystem zu fördern. In Geschirrspülmaschinen ist hierfür eine Laugenpumpe vorgesehen, die hierzu mit einem Leitungssystem des wasserführenden Haushaltsgeräts in Verbindung steht.Water-carrying household appliances, such as dishwashers, have a pipeline system that allows washing liquor to be conveyed out of the water-carrying household appliance into a domestic wastewater disposal system after a cleaning process has ended. For this purpose, a drain pump is provided in dishwashers, which for this purpose is connected to a line system of the water-carrying household appliance.

Aus der EP 17 67 788 A1 ist eine Laugenpumpe für eine Geschirrspülmaschine bekannt, die zusätzlich eine Ventilfunktion aufweist, die es erlaubt, unerwünschte Strömungsvorgänge in dem Leitungssystem der Geschirrspülmaschine zu verhindern, z.B. ein Leersaugen des Haushaltsgerätes durch Strömungen in dem hausseitigen Abwasserentsorgungssystem. Dabei ist das Flügelrad in der Pumpe zugleich als Ventilkörper ausgebildet und koaxial entlang einer Achse verschiebbar angeordnet, auf der der Ventilkörper angeordnet ist, wobei die Achse mit einem Motor zum Antrieb der Pumpe in Wirkverbindung steht. Zur axialen Verschiebung des Ventilkörpers zwischen einer geöffneten und einer geschlossenen Position können Federmittel oder alternativ Elektromagnete als Aktuatoren Verwendung finden. Die Vorrichtung gemäß der EP 17 67 788 A1 weist jedoch einen komplizierten Aufbau auf.From the EP 17 67 788 A1 is known a drain pump for a dishwasher, which additionally has a valve function, which allows undesired flow processes in the pipe system of the dishwasher, for example an empty suction of the household appliance by currents in the house-side sewage disposal system. The impeller in the pump is at the same time designed as a valve body and arranged coaxially displaceably along an axis on which the valve body is arranged, the axis being operatively connected to a motor for driving the pump. Spring means or alternatively electromagnets can be used as actuators for the axial displacement of the valve body between an open and a closed position. The device according to the EP 17 67 788 A1 however, has a complicated structure.

Die Geschirrspülmaschine der GB 876 839 A weist eine Umwälzpumpe mit der Zusatzfunktion als Zerkleinerer auf. Ihr "impeller" 152 ist mit einer über einen Motor 42 rotierend angetriebenen "hollow spray tube" 30 gekoppelt, über deren Öffnungen 32 im Spülbehälter Spülflüssigkeit versprüht wird (siehe Seite 1, Spalte 2, Zeilen 82 - 90 und die Figuren 1, 9 und 11). Für diesen Sprühbetrieb nimmt das "valve assembly" 174 eine untere Stellung ein und verschließt die "drain conduit opening" 180 einer Abwasserleitung "drain conduit" 168. Wird die "valve assembly" 174 in eine obere Stellung gebracht, so wird eine Abflußöffnung "drain conduit opening" 180 der Abwasserleitung 168 (siehe Figur 11) geöffnet, so dass das schmutzige Spülwasser am Ende eines Teilspülgangs aus dem Spülbehälter ablaufen kann.The dishwasher of the GB 876 839 A has a circulation pump with the additional function as a shredder. Your "impeller" 152 is coupled to a "hollow spray tube" 30 which is driven in rotation by a motor 42 and through the openings 32 of which spray liquid is sprayed in the washing container (see page 1, column 2, lines 82-90 and FIGS. 1, 9 and 11). For this spraying operation, the "valve assembly" 174 occupies a lower position and closes the "drain conduit opening" 180 of a sewage pipe "drain conduit" 168. If the "valve assembly" 174 is brought into an upper position, then a drain conduit opening 180 of the waste water line 168 (see FIG. 11) is opened so that the dirty washing water can run out of the washing container at the end of a partial washing cycle.

Es ist daher Aufgabe der Erfindung, eine Alternative mit einem einfachen Aufbau anzugeben.It is therefore an object of the invention to provide an alternative with a simple structure.

Die Erfindung geht aus von einem wasserführenden Haushaltsgerät, Wasserführendes Haushaltsgerät, insbesondere Geschirrspül- oder Waschmaschine, wenigstens aufweisend eine mit einem Leitungssystem des wasserführenden Haushaltsgerätes in Verbindung stehende Pumpe, die mit einem Motor in Verbindung steht, und mit einem Ventil mit einem axial bewegbaren Ventilkörper, der am Pumpenrad der Pumpe angeordnet ist. Dabei kann es sich bei der Pumpe mit einem Ventil um eine Laugenpumpe handeln, die dazu dient, am Ende eines Spülvorgangs verschmutzte Spülflotte, die zusätzlich mit Schmutzpartikeln versetzt sein kann, aus einem Behandlungsraum, wie beispielsweise einem Spülbehälter einer Geschirrspülmaschine, in ein hausseitiges Abwasserentsorgungssystem zu fördern. Der Ventilkörper kann unabhängig von dem Pumpenrad zwischen einer ersten Position, in der das Ventil geöffnet ist und einer zweiten Position, in der das Ventil geschlossen ist, bewegt werden, d.h. es handelt sich bei dem Pumpenrad und dem Ventilkörper um zwei Bauteile. Vorzugsweise ist jedoch vorgesehen, die Pumpe mit einem Ventil integral auszuführen, d.h., das Pumpenrad der Pumpe bildet zugleich einen Ventilkörper zum Sperren eines Durchgangs der Pumpe, wobei dieses Bauteil axial, insbesondere axial entlang einer Motorachse zum Antrieb der Pumpe bewegt werden kann, um so das Ventil zu öffnen oder zu schließen.The invention is based on a water-conducting household appliance, water-conducting household appliance, in particular dishwasher or washing machine, at least comprising a pump which is connected to a line system of the water-conducting household appliance and is connected to a motor, and with a valve with an axially movable valve body, which is arranged on the pump impeller of the pump. The pump with a valve can be a drain pump, which is used at the end of a rinsing process to wash the dirty washing liquor, which can also be contaminated with dirt particles, from a treatment room, such as a dishwasher rinse tank, to a sewage disposal system on site promote. The valve body can be moved independently of the impeller between a first position in which the valve is open and a second position in which the valve is closed, i.e. the pump wheel and the valve body are two components. However, it is preferably provided to design the pump integrally with a valve, ie the pump impeller of the pump also forms a valve body for blocking a passage of the pump, this component being able to be moved axially, in particular axially, along a motor axis to drive the pump, and so on to open or close the valve.

Die Aufgabe der Erfindung wird dadurch gelöst, dass der Motor in zwei Drehrichtungen betreibbar ist und das Ventil in Abhängigkeit von der Drehrichtung des Motors öffnet oder schließt. Somit kann durch einfache Art und Weise ein gesteuertes Öffnen und Schließen des Ventils erreicht werden und damit eine Sperrung des Durchgangs der Pumpe. Ferner ist keine Entlüftung der als Laugenpumpe dienenden Pumpe im Fall einer Geschirrspülmaschine nötig.The object of the invention is achieved in that the motor can be operated in two directions of rotation and the valve opens or closes depending on the direction of rotation of the motor. Controlled opening and closing of the valve and thus blocking the passage of the pump can thus be achieved in a simple manner. Furthermore, no venting of the pump serving as a drain pump is necessary in the case of a dishwasher.

Dabei ist bevorzugt vorgesehen, dass der Motor in Wirkverbindung mit dem Ventil steht, sodass sichergestellt ist, dass allein durch die beliebige Drehrichtung des Motors das Ventil geöffnet oder geschlossen wird und nicht durch Strömungsverhältnisse im Leitungssystem des wasserführenden Haushaltsgerätes in ungewollter Weise beeinflusst wird.It is preferably provided that the motor is in operative connection with the valve, so that it is ensured that the valve is opened or closed solely by the arbitrary direction of rotation of the motor and is not influenced in an undesired manner by flow conditions in the line system of the water-carrying household appliance.

Ferner weist das Ventil einen zwischen einer geöffneten und geschlossenen Stellung bewegbaren Ventilkörper auf, wobei bei geöffneter Stellung ein Durchgang von einem Einlass zu einem Auslass der Pumpe freigegeben ist und die Pumpe Spülflotte zu fördern vermag und bei geschlossener Stellung dieser Durchgang geschlossen ist, sodass auch bei strömungsbedingten Unterdruckverhältnissen keine Strömung in dem Leitungssystem des wasserführenden Haushaltsgerätes auftreten kann. Jedoch ist es auch denkbar, dass der Ventilkörper beliebige Stellungen zwischen der geöffneten und der geschlossenen Stellung einnehmen kann, um so beispielsweise eine Mengenregulierung zu ermöglichen.Furthermore, the valve has a valve body which can be moved between an open and closed position, a passage being opened from an inlet to an outlet of the pump in the open position and the pump being able to convey rinsing liquor and this passage being closed in the closed position, so that at flow-related negative pressure conditions, no flow can occur in the pipe system of the water-carrying household appliance. However, it is also conceivable that the valve body can assume any positions between the open and the closed position, so as to enable quantity regulation, for example.

Vorzugsweise ist vorgesehen, dass der Ventilkörper axial entlang einer Motor und Pumpe verbindenden Welle bewegbar ist. Dies erlaubt einen besonders einfachen Aufbau mit einer direkten Verbindung von Motor und Pumpe.It is preferably provided that the valve body can be moved axially along a shaft connecting the motor and the pump. This allows a particularly simple construction with a direct connection between the motor and the pump.

Um in Abhängigkeit von der Drehrichtung des Motors ein Öffnen und Schließen des Ventils zu bewirken ist vorzugsweise zwischen Motor und Ventil ein Getriebe vorgesehen. Dabei wandelt das Getriebe eine Drehbewegung der Welle in eine lineare, zur Welle koaxiale verlaufende Bewegung um. Hierzu weist das Getriebe vorzugsweise eine Gewindespindel auf, die derart ausgebildet ist, dass in Abhängigkeit von einer Drehrichtung, der Ventilkörper aus einer geöffneten in die geschlossene Position bewegt wird und bei Umkehrung der Drehrichtung des Motors aus der geschlossenen in die geöffnete Position bewegt wird.In order to cause the valve to open and close depending on the direction of rotation of the motor, a gear is preferably provided between the motor and the valve. The gearbox converts a rotary movement of the shaft into a linear movement that is coaxial to the shaft. For this purpose, the transmission preferably has a threaded spindle which is designed such that the valve body is moved from an open to the closed position depending on a direction of rotation and is moved from the closed to the open position when the direction of rotation of the motor is reversed.

Als Motor kann jeder in wasserführenden Haushaltsgeräten übliche Elektromotor verwendet werden. Vorzugsweise ist jedoch vorgesehen, dass bürstenlose Gleichstrom- oder Wechselstrommotoren mit Permanentmagneten Verwendung finden, wie beispielsweise BLDC- oder BLAC-Motoren. Bürstenlose Gleichstrom- oder Wechselstrommotoren können eine sensorlose Erfassung der Drehzahl des Motors und damit ein Blockieren des Antriebs erlauben, sodass ohne zusätzlich Sensoren eine Erfassung eines Blockieren des Antriebs erkannt werden kann, insbesondere auch, wenn durch einen Drehrichtungswechsel bedingt das Ventil von der geöffneten in die geschlossene Position oder umgekehrt bewegt wird und die weitere Bewegung durch einen Anschlag begrenzt ist. BLCD- und BLAC-Motoren erlauben ferner einen schnellen Drehrichtungswechsel und damit eine Ausnutzung der Trägheit des Flügelrades der Pumpe, um einen Positionswechsel zu bewirken, ohne das hierzu weitere mechanische Hilfsmittel nötig sind.Any electric motor common in water-bearing household appliances can be used as the motor. However, it is preferably provided that brushless direct current or alternating current motors with permanent magnets, such as BLDC or BLAC motors, are used. Brushless DC or AC motors can allow a sensorless detection of the speed of the motor and thus a blocking of the drive, so that without additional sensors Detection of a blocking of the drive can be detected, in particular also if the valve is moved from the open to the closed position or vice versa due to a change in direction of rotation and the further movement is limited by a stop. BLCD and BLAC motors also allow a quick change of direction of rotation and thus use of the inertia of the impeller of the pump to effect a change of position without the need for further mechanical aids.

Dabei steht vorzugsweise der Motor mit einer Steuerung des wasserführenden Haushaltsgerätes in Erfindung, in der Art, dass ein geschlossenes Ventil erfasst wird und entsprechend der Motor nicht weiter angesteuert wird. Ferner kann so problemlos vorgesehen sein, auf den Fehlerfall zu reagieren, dass ein Blockieren bei einem Drehrichtungswechsel ausbleibt, z.B. durch Nachfüllen einer bestimmten Menge Frischwasser bei gleichzeitigem Abpumpen.The motor with a control of the water-carrying household appliance is preferably in accordance with the invention in such a way that a closed valve is detected and, accordingly, the motor is no longer activated. Furthermore, it can easily be provided to react to the fault that there is no blocking when changing the direction of rotation, e.g. by refilling a certain amount of fresh water with simultaneous pumping.

Ferner ist vorzugsweise vorgesehen, dass eine Ablaufleitung unterhalb des Spülbehälterbodens angeordnet ist, d.h., dass das wasserführende Haushaltsgerät keine einen Siphon bildende Ablaufführung und Ablaufbelüftung aufweist, die eine Rücklaufsperre bilden. Somit weist das wasserführende Haushaltsgerät einen vereinfachten Aufbau auf, wobei der gewonnene Bauraum beispielsweise zur Verbesserung der Dämmung oder zur Anordnung von Zwischenspeichern für Spülflotte verwendet werden kann. Zugleich kann die Pumpe von ihrer Leistungsfähigkeit her geringer dimensioniert werden, was eine Energieersparnis und einen zusätzlichen Bauraumgewinn liefert.Furthermore, it is preferably provided that a drain line is arranged below the bottom of the washing container, i.e. that the water-carrying household appliance does not have a drain guide and drain ventilation forming a siphon, which form a backstop. Thus, the water-carrying household appliance has a simplified structure, and the space gained can be used, for example, to improve the insulation or to arrange intermediate stores for the washing liquor. At the same time, the pump can be dimensioned smaller in terms of its performance, which provides energy savings and additional installation space.

Außerdem ist vorzugsweise vorgesehen, dass eine mit dem Ventilkörper zusammenwirkende Dichtung an einem Deckel der Pumpe angeordnet ist, sodass sich ein besonders einfacher Aufbau ergibt, der auch die Durchführung von Wartungs- oder Instandsetzungsarbeiten erleichtert.In addition, it is preferably provided that a seal which interacts with the valve body is arranged on a cover of the pump, so that there is a particularly simple construction which also facilitates the carrying out of maintenance or repair work.

Erfindungsgemäß ist vorgesehen, dass das Pumpenrad der Pumpe zusammen mit dem Ventilkörper des Ventils axial bewegbar angeordnet ist, d.h. Pumpenrad und Ventilkörper sind ein Bauteil und zwischen einer ersten Position bewegbar, in der das Ventil geöffnet ist und einer zweiten Position, in der das Ventil geschlossen ist.According to the invention, it is provided that the pump wheel of the pump is arranged to be axially movable together with the valve body of the valve, ie the pump wheel and valve body are one component and can be moved between a first position in which the valve is open and a second position in which the valve is closed is.

Ferner gehört zur Erfindung eine erfindungsgemäße Pumpe für ein erfindungsgemäßes Haushaltsgerät.The invention also includes a pump according to the invention for a household appliance according to the invention.

Im Folgenden wird die Erfindung anhand der Zeichnung erläutert. Es zeigt:

Das Flügelrad 14 weist an seinem vorderen Ende einen Ventilkörper 20 auf, der in der geschlossenen Position (nicht dargestellt) an der Innenseite des Pumpenraums 22 angeordneten Dichtung 10 anliegt und so einen sicheren Verschluss des Durchgangs der Pumpe bewirkt. Zur Abdichtung ist ferner am Pumpendeckel 16 eine weitere Dichtung 12 vorgesehen.At its front end, the impeller 14 has a valve body 20 which, in the closed position (not shown), bears against the seal 10 arranged on the inside of the pump chamber 22 and thus securely closes the passage of the pump. A further seal 12 is also provided on the pump cover 16 for sealing.

Zusammen bilden der Ventilkörper 20 und die Dichtung 10 das Ventil 4. Dabei ist der Ventilkörper 20 mit dem Flügelrad 14 fest verbunden und insbesondere einstückig, beispielsweise aus Kunststoff, gebildet.Together, the valve body 20 and the seal 10 form the valve 4. The valve body 20 is firmly connected to the impeller 14 and in particular is formed in one piece, for example from plastic.

Das Flügelrad 14 weist ferner ein ein Spindelgetriebe aufweisendes Gewinde 8 auf, das in Eingriff mit der Welle 6 steht und es erlaubt, dass je nach Drehrichtung der Welle 6 das Flügelrad 14 mit dem Ventilkörper 20 von der geöffneten in die geschlossene Position oder umgekehrt bewegt wird. Hierzu wandelt das Spindelgetriebe (nicht dargestellt) des Getriebes 8 die Drehbewegung der Welle 6 in eine koaxial zur Welle 6 verlaufende, lineare, drehrichtungsabhängige Hin- und Herbewegung des Ventilskörpers 20 um.The impeller 14 also has a thread 8 having a spindle gear, which is in engagement with the shaft 6 and allows, depending on the direction of rotation of the shaft 6, the impeller 14 with the valve body 20 to be moved from the open to the closed position or vice versa . For this purpose, the spindle gear (not shown) converts the Gear 8, the rotary movement of the shaft 6 in a coaxial to the shaft 6, linear, rotational direction-dependent back and forth movement of the valve body 20.

Im Betrieb erfolgt ein Öffnen des Ventils 4 durch Ansteuern des Motors 18, worauf durch das Getriebe 8 eine Umwandlung der Drehbewegung der Welle 6 in eine lineare Verschiebung des Ventilkörpers 20 aus der geschlossen in die in Fig. 1 dargestellt offene Position erfolgt. Wenn diese Position erreicht ist, stoppt ein Anschlag (nicht dargestellt) diese Bewegung. Zugleich erfasst die Steuerung der Geschirrspülmaschine, dass diese Bewegung durch den Anschlag blockiert ist und beendet hierauf diesen Vorgang. Anschließend kann Flüssigkeit durch antreiben des Flügelrades 4 gefördert werden. Zum Verschließen wird der Motor 18 in entgegen gesetzter Richtung angetrieben, sodass der Ventilkörper 20 aus der offenen in die geschlossene Position bewegt wird, bis diese Bewegung wieder durch einen Anschlag begrenzt und von der Steuerung erfasst wird.In operation, the valve 4 is opened by actuating the motor 18, whereupon the transmission 8 converts the rotary movement of the shaft 6 into a linear displacement of the valve body 20 from the closed position to the position shown in FIG Fig. 1 shown open position takes place. When this position is reached, a stop (not shown) stops this movement. At the same time, the control of the dishwasher detects that this movement is blocked by the stop and then ends this process. Then liquid can be conveyed by driving the impeller 4. For closing, the motor 18 is driven in the opposite direction, so that the valve body 20 is moved from the open to the closed position until this movement is again limited by a stop and is detected by the control.
