Description
Die Erfindung betrifft ein wasserführendes Haushaltsgerät nach dem Oberbegriff des Patentanspruchs 1. Ferner betrifft die Erfindung eine Elektronikbaugruppe und einen Flüssigkeitssensor.The The invention relates to a water-conducting household appliance according to the The preamble of claim 1. Furthermore, the invention relates an electronic assembly and a liquid sensor.
In wasserführenden Haushaltsgeräten, wie beispielsweise Geschirrspülern, wird ein Bodenwannenschwimmer verwendet, der durch die Auftriebskraft von Leckagewasser ab einer bestimmten Leckagewassermenge einen Mikroschalter betätigt. Eine mit dem Mikroschalter in Verbindung stehende Steuerung des wasserführenden Haushaltsgeräts veranlasst daraufhin, dass ein Füllventil geschlossen und die Laugenpumpe eingeschaltet wird. Wenn der Mikroschalter/Sensor zusätzlich mit einer Überlaufleitung verbunden ist, kann außerdem ein Überlaufen aufgrund eines Überfüllens des Geschirrspülers erfasst werden.In water-bearing Household appliances, such as dishwashers, a floor pan float is used, which is controlled by the buoyancy force of leakage water from a certain amount of leakage water a microswitch actuated. A with the microswitch related control of the aquifer Home appliance causes then that a filling valve closed and the drain pump is turned on. When the microswitch / sensor additionally with an overflow line can be connected as well an overflow due overfilling the dishwasher be recorded.

Es ist daher Aufgabe der Erfindung ein wasserführendes Haushaltsgerät mit einem vereinfachten Leckagesensor bereitzustellen.It is therefore an object of the invention is a water-conducting household appliance with a to provide simplified leakage sensor.
Die Aufgabe der Erfindung wird gelöst durch ein wasserführendes Haushaltsgerät mit den Merkmalen des Patentanspruchs 1. Dadurch, dass die Sensor-Empfänger-Einheit auf einer Elektronikbaugruppe angeordnet ist, wird ein kompaktes Bauteil bereitgestellt, dass einfach in ein wasserführendes Haushaltsgerät zu montieren ist und insbesondere eine Montage ohne nachfolgende Justierung erlaubt.The The object of the invention is achieved through a water-bearing household appliance With the features of claim 1. By virtue of the fact that the sensor-receiver unit is arranged on an electronic assembly, becomes a compact Component provided that easy to mount in a water-bearing household appliance is and in particular a mounting without subsequent adjustment allowed.
Die Messstrecke kann durch die an dem ersten Ende der Messstrecke angeordnete Sender-/Empfängereinheit und ein am zweiten Ende angeordnetem Reflexionselement gebildet sein. Dabei kann das Reflexionselement ein separates Bauteil, wie z.B. ein Spiegel oder ein Bodenabschnitt mit Reflexionseigenschaften im Inneren eines Haushaltsgeräts sein. In einer bevorzugten Ausführungsform ist vorgesehen, dass die Messstrecke durch einen Tauchstab gebildet ist. Dabei kann der Tauchstab aus einem lichtdurchlässigem Material, beispielsweise einem geeigneten Kunststoffmaterial, gefertigt sein. Der Tauchstab kann dabei derart unterhalb oder neben einer elektronischen Steuerung angeordnet sein, dass die Sender-/Empfängereinheit auf der elektronischen Steuerung angeordnet werden kann.The Measuring path can be arranged by the at the first end of the measuring section Transmitter / receiver unit and a reflection element disposed on the second end is formed be. In this case, the reflection element may be a separate component, such as e.g. a mirror or floor section with reflective properties inside a household appliance be. In a preferred embodiment is provided that the measuring section formed by a dipstick is. In this case, the dipstick made of a translucent material, for example, a suitable plastic material to be made. Of the Dipstick can be so below or next to an electronic Control be arranged that the transmitter / receiver unit on the electronic Control can be arranged.
Das Reflexionselement kann derart ausgebildet sein, dass bei Abwesenheit von Flüssigkeit in dem zu überwachenden Bereich keine Reflexions-, insbesondere keine Totalreflexionsbedingungen, gegeben sind. Vorzugsweise ist jedoch vorgesehen, dass das Reflexionselement derart ausgebildet ist, das bei Anwesenheit von Flüssigkeit in dem zu überwachenden Bereich keine Reflexions-, insbesondere keine Totalreflexionsbedingungen, gegeben sind. Dabei kann das Reflexionselement als prismenförmiger Abschnitt am zweiten Ende der Messstrecke angeordnet sein, wobei die Winkelgestaltung des Prismenabschnitts unter Berücksichtigung des Brechungsindex derart gewählt wird, dass bei Anwesenheit von Flüssigkeit keine Reflexions- oder Totalreflexionsbedingungen gegeben sind.The Reflection element can be designed such that in the absence of liquid in the to be monitored Range no reflection, in particular no total reflection conditions, given are. Preferably, however, it is provided that the reflection element is formed in the presence of liquid in the to be monitored Range no reflection, in particular no total reflection conditions, given are. In this case, the reflection element as a prism-shaped section be arranged at the second end of the measuring section, wherein the angle design of the prism section under consideration of the refractive index selected is that in the presence of liquid no reflection or total reflection conditions are given.
In einer bevorzugten Ausführungsform ist vorgesehen, dass die Sender/Empfänger-Einheit zum Aussenden und Empfangen von Licht ausgebildet ist. Hierzu kann als Sender eine Leuchtdiode und als Empfänger ein Fototransistor verwendet werden. Jedoch können auch andere Bauelemente zur Erzeugung und Erfassung von elektromagnetischen oder anderen Signalen verwendet werden. Die Sender-/Empfänger-Einheit kann zum Aussenden und Empfangen von beliebigen Signalen, wie z.B. Licht-, Ultraschall-, UV- oder Infrarotsignalen ausgebildet sein.In a preferred embodiment is provided that the transmitter / receiver unit for sending and receiving is formed of light. For this purpose, as a transmitter, a light emitting diode and as a receiver a phototransistor can be used. However, other components can also be used for the generation and detection of electromagnetic or other Signals are used. The transmitter / receiver unit can transmit and receive of any signals, e.g. Light, ultrasonic, UV or Infrared signals to be formed.
In einer bevorzugten Ausführungsform ist vorgesehen, dass die Elektronikbaugruppe derart ausgebildet ist, das sie im eingebauten Zustand oberhalb dem auf Leckagen zu überwachenden Bereich angeordnet ist. Hierdurch wird ein besonders einfacher Aufbau erreicht, bei dem sich der Tauchstab nach unten in den auf Leckagen zu überwachenden Bereich erstreckt. Dabei kann die Fixierung des Tauchstabs mittels einer im Bodenbereich des zu überwachenden Bereichs vorgesehenen Halterung erfolgen oder allein durch eine Rastverbindung an einem Gehäuse, in der die elektronische Steuerung vor Spritzwasser geschützt aufgenommen ist.In a preferred embodiment it is envisaged that the electronic assembly designed in this way is that they are in the installed state above the leak to monitor Area is arranged. This will be a particularly simple structure reached, with which the dipstick down in the on leaks area to be monitored extends. Here, the fixation of the dipstick by means of a in the floor area of the monitored Area provided bracket or alone by a Locking connection to a housing, in which the electronic control is protected against splashing water is.
