Definitions
- the invention relates to a household appliance and a method for operating a household appliance.
- a washing machine has a water switch, which directs a flow of water to the various detergent chambers.
- a water diverter to direct a flow of water to the various spray arms in the tub.
- Such water switches can be understood as an electrically controllable actuator and are usually stored in their position variable to lock or unlock the respective outflows.
- a water diverter from its first position in which it directs water from an inflow only into a first outflow, may be transferred by an electrical signal from a controller to a second position in which the diverter allows a flow of water only into a second outflow, but not more in the first outflow.
- the positions can also be approached in the transition area.
- a sensor which detects a reference position of the water switch. Since a drive of the water switch is usually done via a synchronous motor, based on the reference position and the engine revolutions and possibly a gear ratio starting from the reference position each position be approached controlled. Conventionally, for example, a stationary mechanical position switch interacts with the water switch so that the reference position is determined when the position switch contacts the water switch.
- the household appliance has a water pipe system.
- an inflow is typically led to a branch, from which branch several, ie at least two outflows depart.
- inflow and outflows are formed as tubes.
- the inflow is acted upon at least temporarily in the operation of the household appliance with water, which, possibly already added with a detergent, depending on the type of device used to clean, for example, textiles or crockery.
- a water switch is now arranged, preferably at or near the junction.
- the water diverter serves to direct the water supplied via the inflow into a selection of outflows.
- the respective selection of outflows preferably depends on the program operation.
- such a selection of outflows can also contain no outflow, if in a certain section of the program operation no outflow of water should lead.
- the water diverter preferably assumes a position in which all outlets are closed by the water diverter, and preferably by a closure part of the water diverter become.
- Another choice may include a single one of the outlets, so that the water supplied is routed through this one drain, whereas other outlets through the water diverter are closed at the same time.
- such a selection may also include multiple or all outflows, so that the supplied water is split among these multiple or all outflows.
- the household appliance also has a turbidity sensor.
- This turbidity sensor is designed to measure turbidity of water in the water pipe system.
- Water in the water pipe system may in particular be rinse water, which, for example, a water cycle, the constituent part including the aforementioned water pipe system and the tub with the material to be cleaned, passes through several times and is thus brought together several times for cleaning with the material to be cleaned. Such an operation lowers the water consumption of the household appliance.
- the rinsing water may no longer have sufficient cleaning power due to the repeated absorption of dirt at a certain point in time.
- the above turbidity sensor may be used, which detects turbidity in this water, and may preferably detect a degree of turbidity.
- the turbidity sensor may be an optical sensor having an optical transmitter and an optical receiver.
- the turbidity sensor can also be designed as a forked or reflex light barrier.
- the dirt particles present in the water absorb or reflect the light of the transmitter, so that the received light output in the above embodiment can be regarded as a measure of the turbidity of the water.
- an associated controller may modify the operation of the household appliance, and for example, remove and divert the water consumed from the water cycle, or else Add fresh water, or increase the detergent concentration in the water by adding detergent or affect the transit times or temperature guides.
- the water switch and the turbidity sensor are now arranged to one another such that at least one reference position of the water switch is detectable by the turbidity sensor.
- the turbidity sensor is thus not only used to detect the turbidity of passing water, but also serves to detect at least one specific position of the water switch, the so-called reference position, which, as described above, can serve as a starting point, the water gate in combination with To convert a defined number of revolutions of the drive from the reference position or another position in a desired position, for example, to release a certain outflow.
- the turbidity sensor thus assumes two functions, since it can detect at least a single, but possibly also a plurality of positions of the movably mounted part (s) of the water separator due to its arrangement relative to the water switch and in particular to its closure part.
- the water switch and in particular its closure part has a projection which cooperates with the turbidity sensor.
- the projection may serve as a breaker for the optical path between transmitter and receiver. Since the receiver preferably a shading detects the emitted light, a shading caused by the projection is high compared to a caused by a water turbidity shading, so that is preferably recognized on the caused by the projection shading when the received light power falls below a predetermined threshold.
- the closure part of the water switch is rotatably mounted. It may have one or more openings allowing the passage of water from the inflow into one or more outlets, provided that the water diverter is positioned so that the respective opening coincides with an inlet of the associated outflow.
- the at least one opening is not arranged symmetrically with respect to an axis of rotation of the closure part, so that in different positions of the closure part a flow into the respective outflow (s) can be enabled or disabled.
- the above-mentioned projection as a preferred means for cooperation with the turbidity sensor may be arranged at a rotatably mounted closure member with a preferably circular circumference at this circumference.
- the closure part may take the form of a plate whose circumference is ultimately formed only approximately circular due to the projection.
- a hole pattern in the water switch can take over this function.
- coded hole patterns in which a direction of rotation can be detected can be realized, for example, by a long and a short shading of the light barrier next to each other.
- the inflow is preferably connected to a pump which pumps water from a sump of the tub to different spray arms.
- the water pipe system with the water switch the Take over distribution of water on the spray arms, wherein preferably a first spray arm is connected to a first outlet of the water pipe system, and a second spray arm with a second drain of the water pipe system.
- the household appliance may also be designed as a washing machine.
- an operation of the household appliance is controlled as a function of a measured turbidity of water in a water pipe system of the household appliance.
- a reference position of a water diverter provided for directing water in the water supply system between an inflow and a plurality of outlets is recognized by the measured turbidity.
- the water switch is converted based on the determined reference position in a defined position.
- FIG. 1 shows a cut-open water pipe system 1 with a water diverter 2 in plan view, according to an embodiment of the invention.
- the water pipe system 1 is cut open in the region of a branch 15.
- Above the junction 15, so outstanding from the drawing level would join various outflows, in the present example three drainpipes, which are separated from the inflow through the water separator 2.
- a plate-shaped closure part 21 can be seen, which separates the inflow from the drains.
- the closure member 21 is rotatably supported about a shaft 26.
- the closure member 21 has three openings / openings 23, 24 and 25, which, if they are brought into agreement with the drains by rotation of the closure member 21, establish a continuous connection of the respective outflow with the inflow, so that supplied via the inflow water in the relevant outflow is directed.
- the closure member 21 in such a position must allow access to all three drains simultaneously through openings 23-25. There may therefore be positions of the closure part 21 in which only one of the outflows is connected to the inflow by means of the branch 15 in each case.
- the geometry of the closure part 21 depends on distribution patterns for the supplied water. For example, if an operating program of the household appliance requires the simultaneous admission of several outlets, then the closure part 21 is geometrically designed such that that in a position of the closure part 21, two or more of its openings correspond to the respective drains. When turning the closure part 21 so rotate its openings 23-25 and can be brought into correspondence with one or more drains.
- the closure part 21 of the water switch 2 has in this embodiment, a projection 22 which protrudes from the otherwise circular circumference of the closure part 21.
- the projection 22 In the present position of the closure member 21, the projection 22 at least partially overlies an optical receiver 32 mounted in the branch 15.
- An unillustrated, arranged above the plane of the optical transmitter emits a light signal to the optical receiver 32 from.
- This light signal which defines an optical path between the transmitter and the receiver 32, is at least partially interrupted by the projection 22 in the illustrated position of the closure part 21. This interruption manifests itself in the signal emitted by the optical receiver 32 as a collapse in the received light power.
- turbidity sensor by evaluating this signal of the so-called turbidity sensor, a reference position of the closure part 21 and thus of the water switch 2 can be detected.
- the senor serves as a turbidity sensor for detecting turbidity of the water passed between the transmitter and the receiver 32 due to which observed turbidity of operation of the household appliance, for example its program flow, can be influenced.
- FIG. 2 shows a schematic water pipe system 1 in a household appliance in a longitudinal section, according to an embodiment of the invention.
- the inflow 11 is now visible in the form of a tube, is supplied via the water of the branch 15 and thus the water switch 2.
- the inflow 11 opens into the branch 15, in which branch 15 the closure part 21 is arranged.
- the closure part 21 closes or opens paths, in this example three outflows 12, 13 and 14. In this case, only the outflow 12 lies in the selected sectional plane.
- the drains 13 and 14 are arranged offset to the cutting plane, which is expressed by the hatching. It can be seen that the outflows 12-14 can not only have different radii, but can also be arranged radially offset relative to the shaft for the water distributor 2.
- the closure member 21 just at a position in which an opening 23 is brought into conformity with the drain 12, so that the water supplied via the inflow 11 is fed into the drain 12. It is assumed that the inlets to the other two drains 13 and 14 are closed in this position of the closure part 21 by the same.
- FIG. 2 a drive 27 for the shaft 26 and thus the closure part 21 is shown.
- the drive 27 is an actuator with a stepper motor and a gearbox for endless rotation of the closure part 21.
- the drive 27 is controlled by a controller 4. So if another outflow as drain 12 record the water supplied, so causes the Control 4 a signal to the drive 27, the closure member 21 a defined time and thus to rotate by a certain angle to then release the other drain in the new position through an associated opening, and at the same time the drain 12 through the closure part 21st to close again.
- the controller 4 receives a signal from the turbidity sensor 3, which is now shown in section and has an optical receiver 32 and an optical transmitter 31.
- the arrow 33 indicates an optical path between transmitter 31 around receiver 32. If the projection 22 of the closure part 21 interrupts the optical path 33, Thus, a significant loss in the signal strength of the receiver is detected by the controller 4, so that in this case can be closed to the reference position of the closure part 21, in which just the projection 22 passes the turbidity sensor 3. This reference position now uses the controller 4 again for precise positioning of the closure part 21.
- the turbidity sensor 3 also supplies its signal to the controller 4 for another purpose. If the water conducted past the turbidity sensor 3 is contaminated and contains, for example, many particles, these particles cause shading and thus a signal of reduced intensity at the receiver 32 Turbidity of the past water may lead to a change in the operation of the household appliance. Thus, for example, fresh water can be mixed into the water cycle, the program times and the temperature control are influenced, etc.
- the interaction of the closure part 21 with the turbidity sensor 3 is preferably such that the signal caused by the interaction with the water separator is quantitatively significantly different from the signal caused by a clouding of water.

Abstract
Description
Die Erfindung betrifft ein Haushaltsgerät sowie ein Verfahren zum Betreiben eines Haushaltsgeräts.The invention relates to a household appliance and a method for operating a household appliance.
Haushaltsgeräte mit flüssigkeitsbasierten Reinigungsmechanismen weisen häufig eine sogenannte Wasserweiche auf. Beispielsweise weist eine Waschmaschine eine Wasserweiche auf, die einen Wasserzufluss auf die diversen Waschmittelkammern leitet. In Geschirrspülern kann einen Wasserweiche vorgesehen sein, um einen Wasserzufluss auf die diversen Spritzarme im Bottich zu leiten.Domestic appliances with liquid-based cleaning mechanisms often have a so-called water switch. For example, a washing machine has a water switch, which directs a flow of water to the various detergent chambers. In dishwashers may be provided a water diverter to direct a flow of water to the various spray arms in the tub.
Solche Wasserweichen können als elektrisch ansteuerbares Stellglied verstanden werden und sind gewöhnlich in ihrer Position veränderlich gelagert, um die jeweiligen Abflüsse zu sperren oder freizugeben. So mag beispielsweise eine Wasserweiche aus ihrer ersten Position, in der sie Wasser aus einem Zufluss nur in einen ersten Abfluss leitet, durch ein elektrisches Signal einer Steuerung in eine zweite Position überführt werden, in der die Wasserweiche einen Wasserfluss lediglich in einen zweiten Abfluss erlaubt, nicht jedoch mehr in den ersten Abfluss. Die Positionen können auch im Übergangsbereich angefahren werden.Such water switches can be understood as an electrically controllable actuator and are usually stored in their position variable to lock or unlock the respective outflows. For example, a water diverter from its first position, in which it directs water from an inflow only into a first outflow, may be transferred by an electrical signal from a controller to a second position in which the diverter allows a flow of water only into a second outflow, but not more in the first outflow. The positions can also be approached in the transition area.
Um die Position der Wasserweiche genau einstellen zu können, ist gewöhnlich ein Sensor vorgesehen, der eine Referenzposition der Wasserweiche erkennt. Da ein Antrieb der Wasserweiche meistens über einen Synchronmotor erfolgt, kann auf Basis der Referenzposition und der Motorumdrehungen und allenfalls einer Getriebeübersetzung ausgehend von der Referenzposition jede Position gesteuert angefahren werden. Herkömmlich wirkt beispielsweise ein stationärer mechanischer Positionsschalter mit der Wasserweiche zusammen, sodass bei einem Kontakt des Positionsschalters mit der Wasserweiche die Referenzposition ermittelt ist.To accurately adjust the position of the water switch, a sensor is usually provided which detects a reference position of the water switch. Since a drive of the water switch is usually done via a synchronous motor, based on the reference position and the engine revolutions and possibly a gear ratio starting from the reference position each position be approached controlled. Conventionally, for example, a stationary mechanical position switch interacts with the water switch so that the reference position is determined when the position switch contacts the water switch.
Ein solcher Positionsschalter ist jedoch ein zusätzliches Bauteil, das es zu verkabeln und zu überwachen gilt. Insofern besteht der Wunsch nach einer aufwandsarmen Referenzpositionserkennung für eine Wasserweiche in einem Haushaltsgerät.However, such a position switch is an additional component that has to be wired and monitored. In this respect, there is a desire for a low-cost reference position detection for a water switch in a household appliance.
Diese Aufgabe wird gelöst durch ein Haushaltsgerät mit den Merkmalen des Patentanspruchs 1. Das Haushaltsgerät weist ein Wasserleitungssystem auf. Darin wird typischerweise ein Zufluss zu einer Verzweigung geführt, von welcher Verzweigung mehrere, also mindestens zwei Abflüsse abgehen. Vorzugsweise sind Zufluss und Abflüsse als Rohre ausgebildet. Typischerweise wird der Zufluss zumindest zeitweise im Betrieb des Haushaltsgeräts mit Wasser beaufschlagt, das, gegebenenfalls bereits mit einem Reinigungsmittel versetzt, je nach Gerätetypus der Reinigung von beispielsweise Textilien oder Geschirr dient. Zwischen Zufluss und Abflüssen ist nun eine Wasserweiche angeordnet, vorzugsweise an oder in der Nähe der Verzweigung. Die Wasserweiche dient dazu, das über den Zufluss zugeführte Wasser in eine Auswahl der Abflüsse zu leiten. Die jeweilige Auswahl der Abflüsse richtet sich dabei vorzugsweise nach dem Programmbetrieb. So kann eine solche Auswahl der Abflüsse auch keinen Abfluss enthalten, wenn in einem bestimmten Abschnitt des Programmbetriebs kein Abfluss Wasser führen soll. Hierbei nimmt die Wasserweiche vorzugsweise eine Position ein, in der alle Abflüsse durch die Wasserweiche, und vorzugsweise durch ein Verschlussteil der Wasserweiche verschlossen werden. Eine andere Auswahl mag einen einzigen der Abflüsse umfassen, sodass das zugeführte Wasser über diesen einen Abfluss weitergeleitet wird, wohingegen andere Abflüsse durch die Wasserweiche gleichzeitig verschlossen werden. Eine solche Auswahl mag aber auch mehrere oder alle Abflüsse umfassen, sodass das zugeführte Wasser aufgeteilt wird auf diese mehreren oder alle Abflüsse.This object is achieved by a household appliance with the features of
Das Haushaltsgerät weist weiterhin einen Trübungssensor auf. Dieser Trübungssensor ist dazu bestimmt, eine Trübung von Wasser in dem Wasserleitungssystem zu messen. Wasser in dem Wasserleitungssystem mag insbesondere Spülwasser sein, das beispielsweise einen Wasserkreislauf, dessen Bestandteil unter anderem auch das vorgenannte Wasserleitungssystem sowie der Bottich mit dem zu reinigenden Gut ist, mehrfach durchläuft und damit mehrfach zum Reinigen mit dem zu reinigenden Gut zusammengebracht wird. Ein solcher Betrieb senkt den Wasserverbrauch des Haushaltsgeräts. Allerdings mag das Spülwasser durch die wiederholte Aufnahme von Schmutz ab einem gewissen Zeitpunkt keine ausreichende Reinigungskraft mehr aufweisen. Zum Feststellen eines solchen verunreinigten Zustandes des Spülwassers mag der obige Trübungssensor dienen, der eine Trübung in diesem Wasser erkennt, und vorzugsweise einen Grad der Trübung feststellen kann.The household appliance also has a turbidity sensor. This turbidity sensor is designed to measure turbidity of water in the water pipe system. Water in the water pipe system may in particular be rinse water, which, for example, a water cycle, the constituent part including the aforementioned water pipe system and the tub with the material to be cleaned, passes through several times and is thus brought together several times for cleaning with the material to be cleaned. Such an operation lowers the water consumption of the household appliance. However, the rinsing water may no longer have sufficient cleaning power due to the repeated absorption of dirt at a certain point in time. To detect such a contaminated state of the rinse water, the above turbidity sensor may be used, which detects turbidity in this water, and may preferably detect a degree of turbidity.
Vorzugsweise kann es sich bei dem Trübungssensor um einen optischen Sensor handeln, der einen optischen Sender und einen optischen Empfänger aufweist. Insbesondere kann der Trübungssensor auch als Gabel- oder Reflexlichtschranke ausgebildet sein. Die im Wasser vorhandenen Schmutzpartikel absorbieren oder reflektieren dabei das Licht des Senders, sodass die empfangene Lichtleistung in obigem Ausführungsbeispiel als Mass der Trübung des Wassers gewertet werden kann. Abhängig von einer so festgestellten Trübung des Wassers kann eine zugehörige Steuerung den Betrieb des Haushaltsgeräts modifizieren, und beispielsweise das verbrauchte Wasser aus dem Wasserkreislauf entnehmen und ableiten, oder aber weiteres Frischwasser zuführen, oder aber die Waschmittelkonzentration im Wasser durch Zufuhr von Waschmittel erhöhen oder die Laufzeiten oder Temperaturführungen beeinflussen. Dies sind nur einige repräsentative Beispiele, die darstellen, wie aufgrund eines erkannten Trübungsgrades der Betrieb des Haushaltsgeräts beeinflusst werden kann.Preferably, the turbidity sensor may be an optical sensor having an optical transmitter and an optical receiver. In particular, the turbidity sensor can also be designed as a forked or reflex light barrier. The dirt particles present in the water absorb or reflect the light of the transmitter, so that the received light output in the above embodiment can be regarded as a measure of the turbidity of the water. Depending on such a detected turbidity of the water, an associated controller may modify the operation of the household appliance, and for example, remove and divert the water consumed from the water cycle, or else Add fresh water, or increase the detergent concentration in the water by adding detergent or affect the transit times or temperature guides. These are but a few representative examples that illustrate how, due to a detected level of turbidity, the operation of the household appliance can be affected.
Die Wasserweiche und der Trübungssensor sind nun so zueinander angeordnet, dass zumindest eine Referenzposition der Wasserweiche durch den Trübungssensor erkennbar ist. Der Trübungssensor wird also nicht nur dazu verwendet, die Trübung von vorbei geführtem Wasser zu erkennen, sondern dient auch dem Erkennen zumindest einer spezifischen Position der Wasserweiche, der sogenannten Referenzposition, die, wie zuvor beschrieben, als Ausgangspunkt dienen kann, die Wasserweiche in Kombination mit einer definierten Umdrehungszahl des Antriebs aus der Referenzposition oder einer anderen Position in eine gewünschte Position zu überführen, um beispielsweise einen bestimmten Abfluss freizugeben.The water switch and the turbidity sensor are now arranged to one another such that at least one reference position of the water switch is detectable by the turbidity sensor. The turbidity sensor is thus not only used to detect the turbidity of passing water, but also serves to detect at least one specific position of the water switch, the so-called reference position, which, as described above, can serve as a starting point, the water gate in combination with To convert a defined number of revolutions of the drive from the reference position or another position in a desired position, for example, to release a certain outflow.
Durch die Erfindung kann auf andere Mittel zum Erkennen der Referenzposition der Wasserweiche verzichtet werden. Der Trübungssensor übernimmt damit zwei Funktionen, da er aufgrund seiner Anordnung relativ zur Wasserweiche und insbesondere zu ihrem Verschlussteil zumindest eine einzige, möglicherweise aber auch mehrere Positionen des/der beweglich gelagerten Teils/e der Wasserweiche erkennen kann.By the invention can be dispensed with other means for detecting the reference position of the water switch. The turbidity sensor thus assumes two functions, since it can detect at least a single, but possibly also a plurality of positions of the movably mounted part (s) of the water separator due to its arrangement relative to the water switch and in particular to its closure part.
Vorzugsweise weist die Wasserweiche, und insbesondere ihr Verschlussteil einen Vorsprung auf, der mit dem Trübungssensor zusammenwirkt. Dabei wird im Falle einer optischen Ausgestaltung des Trübungssensors ein optischer Pfad zwischen einem optischen Sender und einem optischen Empfänger durch den Vorsprung nur beeinflusst, wenn sich die Wasserweiche in der Referenzposition befindet. Hier mag der Vorsprung beispielsweise als Unterbrecher für den optischen Pfad zwischen Sender und Empfänger dienen. Da der Empfänger vorzugsweise eine Abschattung des ausgesandten Lichts erkennt, ist eine durch den Vorsprung hervor gerufene Abschattung im Vergleich zu einer durch eine Wassertrübung hervorgerufene Abschattung hoch, sodass auf die durch den Vorsprung hervorgerufene Abschattung vorzugsweise erkannt wird, wenn die empfangene Lichtleistung einen vorgegebenen Schwellwert unterschreitet.Preferably, the water switch, and in particular its closure part has a projection which cooperates with the turbidity sensor. In this case, in the case of an optical design of the turbidity sensor, an optical path between an optical transmitter and an optical receiver is only influenced by the projection when the water separator is in the reference position. Here, for example, the projection may serve as a breaker for the optical path between transmitter and receiver. Since the receiver preferably a shading detects the emitted light, a shading caused by the projection is high compared to a caused by a water turbidity shading, so that is preferably recognized on the caused by the projection shading when the received light power falls below a predetermined threshold.
In einer bevorzugten Weiterbildung der Erfindung ist das Verschlussteil der Wasserweiche drehbar gelagert. Es kann eine oder mehrere Öffnungen aufweisen, die das Durchtreten von Wasser aus dem Zufluss in einen oder mehrere Abflüsse erlauben, sofern die Wasserweiche derart positioniert ist, dass sich die jeweilige Öffnung mit einem Einlass des zugehörigen Abflusses deckt. Vorzugsweise ist die mindestens eine Öffnung nicht symmetrisch bezüglich einer Drehachse des Verschlussteils angeordnet, sodass in unterschiedlichen Positionen des Verschlussteils ein Durchfluss in den/die betreffenden Abflüsse ermöglicht oder gesperrt werden kann.In a preferred embodiment of the invention, the closure part of the water switch is rotatably mounted. It may have one or more openings allowing the passage of water from the inflow into one or more outlets, provided that the water diverter is positioned so that the respective opening coincides with an inlet of the associated outflow. Preferably, the at least one opening is not arranged symmetrically with respect to an axis of rotation of the closure part, so that in different positions of the closure part a flow into the respective outflow (s) can be enabled or disabled.
Der oben erwähnte Vorsprung als bevorzugtes Mittel zum Zusammenwirken mit dem Trübungssensor kann bei einem drehbar gelagerten Verschlussteil mit bevorzugt kreisrundem Umfang an diesem Umfang angeordnet sein. Hier mag das Verschlussteil die Form einer Platte einnehmen, deren Umfang aufgrund des Vorsprungs letztendlich nur noch in etwa kreisrund ausgebildet ist. Alternativ können kann auch ein Lochbild in der Wasserweiche diese Funktion übernehmen. Denkbar sind auch codierte Lochbilder, an denen eine Drehrichtung erkannt werden kann. Diese Codierung kann beispielsweise durch ein langes und ein kurzes Abschatten der Lichtschranke nebeneinander realisiert sein.The above-mentioned projection as a preferred means for cooperation with the turbidity sensor may be arranged at a rotatably mounted closure member with a preferably circular circumference at this circumference. Here, the closure part may take the form of a plate whose circumference is ultimately formed only approximately circular due to the projection. Alternatively, a hole pattern in the water switch can take over this function. Also conceivable are coded hole patterns in which a direction of rotation can be detected. This coding can be realized, for example, by a long and a short shading of the light barrier next to each other.
Ist das Haushaltsgerät beispielsweise als Geschirrspüler ausgebildet, so ist vorzugsweise der Zufluss mit einer Pumpe verbunden, die Wasser aus einem Sumpf des Bottichs zu unterschiedlichen Spritzarmen pumpt. Dabei kann das Wasserleitungssystem mit der Wasserweiche die Verteilung des Wassers auf die Spritzarme übernehmen, wobei bevorzugt ein erster Spritzarm mit einem ersten Abfluss des Wasserleitungssystems verbunden ist, und ein zweiter Spritzarm mit einem zweiten Abfluss des Wasserleitungssystems. In einer Alternative kann das Haushaltsgerät auch als Waschmaschine ausgebildet sein.If the household appliance is designed, for example, as a dishwasher, the inflow is preferably connected to a pump which pumps water from a sump of the tub to different spray arms. Here, the water pipe system with the water switch the Take over distribution of water on the spray arms, wherein preferably a first spray arm is connected to a first outlet of the water pipe system, and a second spray arm with a second drain of the water pipe system. In an alternative, the household appliance may also be designed as a washing machine.
Ferner wird die Aufgabe gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 13. Dabei wird ein Betrieb des Haushaltsgeräts gesteuert in Abhängigkeit einer gemessenen Trübung von Wasser in einem Wasserleitungssystem des Haushaltsgeräts. Eine Referenzposition einer Wasserweiche, die zum Leiten von Wasser in dem Wasserleitungssystem zwischen einem Zufluss und einer Auswahl von mehreren Abflüssen vorgesehen ist, wird durch die gemessene Trübung erkannt. Vorzugsweise wird die Wasserweiche auf Basis der ermittelten Referenzposition in eine definierte Position überführt.Furthermore, the object is achieved by a method having the features of
Die obigen Verfahrensschritte können in der angegebenen Reihenfolge, oder aber in einer beliebigen Reihenfolge, sofern technisch sinnvoll, durchgeführt werden.The above process steps can be carried out in the order given, or else in any order, if technically expedient.
Bevorzugte Weiterbildungen, die in Bezug zu dem Haushaltsgerät offenbart sind, sollen auch als zu dem Verfahren zugehörig offenbart gelten, und umgekehrt.Preferred developments, which are disclosed in relation to the domestic appliance, should also be considered to be disclosed as belonging to the method, and vice versa.
Weitere Ausgestaltungen, Vorteile und Anwendungen der Erfindung ergeben sich aus den abhängigen Ansprüchen und aus der nun folgenden Beschreibung anhand der Figuren. Dabei zeigen:
-
FIG. 1 ein aufgeschnittenes Wasserleitungssystem mit einer Wasserweiche in Draufsicht, gemäss einem Ausführungsbeispiel der Erfindung, und -
FIG. 2 ein schematisches Wasserleitungssystem in einem Haushaltsgerät im Längsschnitt, nach einem Ausführungsbeispiel der Erfindung.
-
FIG. 1 a cut-open water supply system with a water diverter in plan view, according to an embodiment of the invention, and -
FIG. 2 a schematic water pipe system in a household appliance in a longitudinal section, according to an embodiment of the invention.
Von der Wasserweiche 2 ist insbesondere ein plattenförmiges Verschlussteil 21 zu sehen, das den Zufluss von den Abflüssen separiert. Das Verschlussteil 21 ist drehbar um eine Welle 26 gelagert. Das Verschlussteil 21 weist drei Öffnungen/Durchbrüche 23, 24 und 25 auf, die, sofern sie in Überseinstimmung mit den Abflüssen durch Rotation des Verschlussteils 21 gebracht sind, eine durchgängige Verbindung des betreffenden Abflusses mit dem Zufluss herstellen, sodass über den Zufluss zugeführtes Wasser in den betreffenden Abfluss geleitet wird. Es ist aber nicht notwendigerweise so, dass das Verschlussteil 21 in einer solchen Position den Zugang zu allen drei Abflüssen gleichzeitig über Öffnungen 23-25 ermöglichen muss. Es kann deshalb Positionen des Verschlussteils 21 geben, in denen jeweils nur einer der Abflüsse mit dem Zufluss mittels der Verzweigung 15 verbunden ist. In der Praxis richtet sich die Geometrie des Verschlussteils 21 nach Verteilmustern für das zugeführte Wasser. Fordert ein Betriebsprogramm des Haushaltsgeräts beispielsweise die gleichzeitige Beaufschlagung von mehreren Abflüssen, so wird das Verschlussteil 21 geometrisch so gestaltet, dass in einer Position des Verschlussteils 21 zwei oder mehr seiner Öffnungen mit den betreffenden Abflüssen korrespondieren. Beim Drehen des Verschlussteils 21 rotieren also seine Öffnungen 23-25 mit und können in Korrespondenz mit einem oder mehreren Abflüssen gebracht werden.Of the
Das Verschlussteil 21 der Wasserweiche 2 weist in diesem Ausführungsbeispiel einen Vorsprung 22 auf, der aus dem im Übrigen kreisrunden Umfang des Verschlussteils 21 hervorragt. In der gegenwärtigen Position des Verschlussteils 21 überdeckt der Vorsprung 22 zumindest teilweise einen optischen Empfänger 32, der in der Verzweigung 15 angebracht ist. Ein nicht dargestellter, oberhalb der Zeichenebene angeordneter optischer Sender sendet ein Lichtsignal an den optischen Empfänger 32 aus. Dieses Lichtsignal, das einen optischen Pfad zwischen dem Sender und dem Empfänger 32 definiert, wird in der dargestellten Position des Verschlussteils 21 durch den Vorsprung 22 zumindest teilweise unterbrochen. Dieser Unterbruch äussert sich in dem vom optischen Empfänger 32 abgegebenen Signal als Einbruch in der empfangenen Lichtleistung. Insofern kann durch Auswertung dieses Signals des sogenannten Trübungssensors eine Referenzposition des Verschlussteils 21 und somit der Wasserweiche 2 erkannt werden. Über das Erkennen der Referenzposition des Verschlussteils 21 hinaus dient der Sensor als Trübungssensor zum Erfassen einer Trübung des zwischen Sender und dem Empfänger 32 vorbei geführten Wassers aufgrund welcher festgestellten Trübung der Betrieb des Haushaltsgeräts, beispielsweise sein Programmablauf, beeinflusst werden kann.The
Im vorliegenden Beispiel weist das Verschlussteil 21 gerade eine Position auf, in der eine Öffnung 23 in Übereinstimmung mit dem Abfluss 12 gebracht ist, sodass das über den Zufluss 11 zugeführte Wasser in den Abfluss 12 geleitet wird. Es wird angenommen, dass die Einlässe zu den anderen beiden Abflüssen 13 und 14 in dieser Position des Verschlussteils 21 durch selbiges verschlossen sind.In the present example, the
Ferner ist in
Die Steuerung 4 erhält ein Signal von dem Trübungssensor 3, der nun im Schnitt gezeigt ist und einen optischen Empfänger 32 und einen optischen Sender 31 aufweist. Der Pfeil 33 zeigt einen optischen Pfad zwischen Sender 31 um Empfänger 32 an. Unterbricht der Vorsprung 22 des Verschlussteils 21 den optischen Pfad 33, so wird ein signifikanter Verlust in der Signalstärke des Empfängers durch die Steuerung 4 erkannt, sodass in diesem Falle auf die Referenzposition des Verschlussteils 21 geschlossen werden kann, in der eben der Vorsprung 22 den Trübungssensor 3 passiert. Diese Referenzposition nutzt nun die Steuerung 4 wiederum zum präzisen Positionieren des Verschlussteils 21.The
Der Trübungssensor 3 liefert sein Signal auch zu einem anderen Zweck an die Steuerung 4. Ist das am Trübungssensor 3 vorbei geführte Wasser verschmutzt und enthält beispielsweise viele Partikel, so verursachen diese Partikel eine Abschattung und damit ein Signal geminderter Stärke am Empfänger 32. Eine solche festgestellte Eintrübung des vorbei geführten Wassers mag zu einem veränderten Betrieb des Haushaltsgeräts führen. So kann aufgrund dessen etwa Frischwasser in den Wasserkreislauf beigemischt werden, die Programmzeiten und die Temperaturführung beeinflusst werden, etc. Die Interaktion des Verschlussteils 21 mit dem Trübungssensor 3 ist vorzugsweise dergestalt, dass sich das Signal hervorgerufen durch die Wechselwirkung mit der Wasserweiche quantitativ signifikant unterscheidet von dem Signal hervorgerufen durch eine Eintrübung von Wasser.The
Während in der vorliegenden Anmeldung bevorzugte Ausführungen der Erfindung beschrieben sind, ist klar darauf hinzuweisen, dass die Erfindung nicht auf diese beschränkt ist und in auch anderer Weise innerhalb des Umfangs der folgenden Ansprüche ausgeführt werden kann. Insbesondere kann die Anordnung der Zu- und Abflüsse der Wasserweiche in beliebigen Winkeln erfolgen.While preferred embodiments of the invention are described in the present application, it is to be understood that the invention is not limited thereto and may be embodied otherwise within the scope of the following claims. In particular, the arrangement of the inflows and outflows of the water diverter can be done at any angle.
