Es ist Aufgabe der vorliegenden Erfindung, eine alternative Einrichtung zur Überwachung des Betriebsablaufs einer Geschirrspülmaschine anzugeben, mit welcher die Drehbewegung eines Sprüharmes der Geschirrspülmaschine auf einfache Weise überwachbar ist und eine alternative Geschirrspülmaschine mit einer derartigen Einrichtung.It Object of the present invention, an alternative device for monitoring indicate the operation of a dishwasher, with which the rotational movement of a spray arm the dishwasher easy to monitor and an alternative dishwasher with such Facility.
Diese Aufgabe wird mit den Merkmalen der Patentansprüche 1 und 9 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Patentansprüchen.These The object is achieved with the features of claims 1 and 9. advantageous Embodiments emerge from the dependent claims.
In einer erfindungsgemäße Einrichtung zur Überwachung des Betriebsablaufs einer Geschirrspülmaschine ist ein in eine Rotationsbewegung versetzbarer Sprüharm vorhanden und eine Überwachungseinrichtung zum Feststellen der Blockierung des Sprüharmes und/oder für die Rotationsbewegung des Sprüharmes, die wenigstens ein Mittel zum Erzeugen eines Magnetfelds vorzugsweise an dem zumindest einen Sprüharm und eine Detektionseinrichtung zur Erfassung des Magnetfelds umfasst, wobei die Überwachungseinrichtung zur Detektion der Änderung der Magnetfeldrichtung ausgebildet ist und das wenigstens eine Mittel zum Erzeugen eines Magnetfeldes ein Magnetfeld in unterschiedlicher Richtung erzeugen kann.In a device according to the invention for monitoring the operation of a dishwasher is in a rotational movement displaceable spray arm present and a monitoring device for detecting the blocking of the spray arm and / or for the rotational movement the spray arm, the at least one means for generating a magnetic field preferably on the at least one spray arm and a detection device for detecting the magnetic field, wherein the monitoring device to detect the change the magnetic field direction is formed and the at least one means for generating a magnetic field, a magnetic field in different Can generate direction.
In einer Ausführungsform weist die Detektionseinrichtung einen Hall-Sensor mit einem nachgeschalteten Schmitt-Trigger auf, wobei bei jeder Feldänderung einer Umschaltung eines von der Detektionseinrichtung abgegebenen Ausgangsignals erfolgt. Dreht sich der Sprüharm, wird durch den Hall-Sensor mit integriertem Schmitt-Trigger die Änderung der Magnetfeldrichtung detektiert. Bei Rotation des Sprüharms ist damit das Ausgangssignal des Schmitt-Trigger alternierend "high" oder "low". Die Messung der Rotation des Sprüharmes ist damit durch eine Zählung der High- und/oder Low-Ausgangssignale möglich.In an embodiment the detection device has a Hall sensor with a downstream one Schmitt trigger on, with each field change a switching of a is output by the detection device output signal. Rotates the spray arm, is changed by the Hall sensor with integrated Schmitt trigger the magnetic field direction detected. On rotation of the spray arm is so that the output signal of the Schmitt trigger alternately "high" or "low". The measurement of Rotation of the spray arm is thus by a count the high and / or low output signals possible.
Gemäß einer weiteren Ausführungsform ist die Detektionseinrichtung außerhalb des Spülbehälters angeordnet, wenn der Spülbehälter aus einem magnetisch nicht schirmenden Material gebildet ist. Die Detektionseinrichtung kann auch am zumindest einen Sprüharm angeordnet sein und das Mittel zum Erzeugen eines Magnetfeldes z. B. im Bereich des Spülbehälters. Umgekehrt bedeutet dies, wenn der Spülbehälter aus einem magnetisch schirmenden Material gebildet ist, sind die Detektionseinrichtung oder zumindest die für die Kopplung eines elektromagnetischen Feldes notwendigen Bestandteile im Inneren des Spülbehälters angeordnet.According to one another embodiment if the detection device is arranged outside the washing container, when the rinse tank off a magnetically non-shielding material is formed. The detection device can also on at least one spray arm be arranged and the means for generating a magnetic field z. B. in the washing container. Vice versa This means when the rinse tank off a magnetically shielding material is formed, the detection device or at least the for the coupling of an electromagnetic field necessary components arranged inside the washing container.
Das Mittel zum Erzeugen eines Magnetfelds an dem zumindest einen Sprüharm ist durch einen ersten und einen zweiten Magnet an dem zumindest einen Sprüharm gebildet. Der erste und der zweite Magnet sind insbesondere als Permanentmagnet oder Elektromagnet ausgebildet.The Means for generating a magnetic field on the at least one spray arm by a first and a second magnet on the at least one spray arm educated. The first and the second magnet are in particular as Permanent magnet or electromagnet formed.
Die magnetischen Pole des ersten und des zweiten Magneten sind weiter senkrecht zur Rotationsrichtung des zumindest einen Sprüharmes angeordnet. Dabei ist der magnetische Nordpol des ersten Magneten dem magnetischen Südpol des zweiten Magneten zugewandt, oder umgekehrt. Es ist weiter vorgesehen, dass der erste Magnet an einem ersten Abschnitt des Sprüharms und der zweite Magnet an einem zweiten Abschnitt des Sprüharms angeordnet sind, wobei der erste und der zweite Abschnitt des Sprüharms durch die Drehachse des Sprüharms voneinander getrennt sind.The magnetic poles of the first and the second magnets are arranged further perpendicular to the direction of rotation of the at least one spray arm. In this case, the magnetic north pole of the first magnet faces the magnetic south pole of the second magnet, or vice versa. It is further contemplated that the first magnet is disposed on a first portion of the spray arm and the second magnet on a second portion of the spray arm, wherein the first and second portions of the spray arm are separated by the axis of rotation of the spray arm.
Es ist gemäß einer weiteren Ausführungsform vorgesehen, dass der erste und der zweite Magnet in einem gleichen Abstand von der Drehachse des Sprüharms auf dem ersten bzw. dem zweiten Abschnitt angebracht sind. Durch diese Maßnahme ist sichergestellt, dass der erste und der zweite Magnet in einem gleichen, definierten Abstand zu der Detektionseinrichtung angeordnet sind. Hierdurch erzeugen sowohl der erste und der zweite Magnet, wenn sich diese im Kopplungsbereich zu der Detektionseinrichtung befinden, ein Signal gleicher Amplitude. Dies ist zwar für das bestimmungsgemäße Funktionieren der Erfindung nicht zwingend notwendig, erleichtert jedoch eine zuverlässige Detektion.It is according to one another embodiment provided that the first and the second magnet in a same Distance from the axis of rotation of the spray arm on the first or the second section are attached. This measure ensures that that the first and the second magnet in a same, defined Spaced to the detection device are arranged. hereby Both the first and second magnets generate when they are located in the coupling region to the detection device, a signal same amplitude. This is true for the proper functioning However, the invention is not absolutely necessary, but facilitates one reliable Detection.
Besonders bevorzugt ist es dabei, wenn der erste und der zweite Magnet im radial äußersten Bereich des ersten und des zweiten Abschnitts des Sprüharms angeordnet sind. Hierdurch werden der erste und der zweite Magnet im kürzestmöglichen Abstand zu der Detektionseinrichtung während einer Rotation vorbeigeführt, wodurch eine maximale Signalkopplung bewirkt ist.Especially it is preferred if the first and the second magnet in radially outermost Area of the first and second portions of the spray arm arranged are. As a result, the first and the second magnet in the shortest possible distance to the detection device during passed a rotation, whereby a maximum signal coupling is effected.
Die Erfindung und deren Vorteile werden nachfolgend anhand eines Ausführungsbeispiels in der Figur näher erläutert.The Invention and its advantages will be described below with reference to an embodiment closer in the figure explained.
