Bei Wäschetrocknern, insbesondere Haushaltswäschetrocknern, besteht der Bedarf, Informationen über die in der Trommel befindlichen Wäsche an die Steuerung des Geräts weiterzugeben. Im Stand der Technik sind die Messungen des Wäschewiderstands über das Elektrodenpaar Mitnehmer-Trommelmantel und die Herausführung dieses Signals mittels Schleifkontakten sowie die Messung der Lufttemperatur am Trommelaustritt bekannt. Der maschinenbauliche Aufwand für die Schleifkontakte ist erheblich, was zu entsprechend hohen Kosten des Wäschetrockners führt. Außerdem kann der prozesstechnisch wichtige Zustand des Riemenrisses nicht erfaßt werden.In the case of clothes dryers, in particular household clothes dryers, there is a need Information about the laundry in the drum to the control of the device pass. In the prior art, the laundry resistance measurements are over the pair of electrodes of the drum-drum jacket and the output of this signal using sliding contacts and measuring the air temperature at the drum outlet known.

Bei einer Waschmaschine wurde gemäß DE 40 31 981 A1 eine Messvorrichtung für Temperatur- und Feuchtegradmessungen des Waschgutes sowie für die Messung der chemischen Zusammensetzung der Waschlauge in einer Waschtrommel einer Waschmaschine vorgeschlagen. Dabei wird eine kugelförmige Messwerterfassungseinrichtung, die eine Sendeeinrichtung hat, zusammen mit der Wäsche in die Trommel der Waschmaschine gelegt. Eine Empfangseinrichtung ist in der Waschmaschine angeordnet und empfängt die von der Messwerterfassungseinrichtung gesendeten Messdaten. Die erfassen Messdaten werden dann einer Steuereinrichtung der Waschmaschine zugeführt.In a washing machine according to DE 40 31 981 A1, a measuring device for Temperature and moisture degree measurements of the laundry as well as for the measurement of chemical composition of the wash liquor in a washing drum Washing machine suggested. This will be a spherical Measured value acquisition device, which has a transmission device, together with the Laundry placed in the drum of the washing machine. A receiving device is in the Washer arranged and receives the from the data acquisition device sent measurement data. The recorded measurement data are then sent to a control device fed to the washing machine.
Ein besonderer Nachteil dieser Messvorrichtung ist, dass der Ort des Senders in der Waschtrommel unbestimmt ist, und die Ausbildung der Messkugel aufwendig ist, da sie gemäß DE 40 31 981 A1 eine Batterie benötigt und die Empfangseinrichtung entsprechend so ausgestaltet werden muss, dass sie jeden möglichen Ort, den die Messkugel erreichen kann, abdeckt. A particular disadvantage of this measuring device is that the location of the transmitter in the Washing drum is indefinite, and the formation of the measuring ball is complex since it according to DE 40 31 981 A1 requires a battery and the receiving device accordingly must be designed in such a way that it covers every possible place the Measuring ball can reach covers.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen Wäschebehandlungsvorrichtung zu schaffen, bei der Messwerte und Informationen über die in der Trommel befindliche Wäsche oder das in der Trommel befindlichen Prozessmedium auf einfache Weise bei hoher Übertragungssicherheit übertragen werden und bei der die Betriebssicherheit erhöht ist.The present invention is therefore based on the object Laundry treatment device to create readings and information about the laundry in the drum or the laundry in the drum Process medium can be transferred easily with high transmission security and with which operational safety is increased.
Diese Aufgabe wird durch einen Wäschetrockner mit den Merkmalen nach Anspruch 1
gelöst.This object is achieved by a clothes dryer with the features of
Eine Wäschebehandlungsvorrichtung insbesondere ein Wäschetrockner ist versehen mit einem Gehäuse, einer Trommel, die in dem Gehäuse drehbar angeordnet ist, einer Messeinrichtung, die zur Erfassung wenigstens eines Parameters der in der Trommel befindlichen Wäsche und/oder dem durch die Trommel geförderten Prozessmedium insbesondere der Prozessluft dient, wobei die Messeinrichtung eine Messwerterfassungseinrichtung und eine am Gehäuse angeordnete Leseeinrichtung umfasst. Die Messwerterfassungseinrichtung ist an der Trommel angeordnet und hat eine Sende- und/oder Empfangseinrichtung, die die Messwerte der Messwerterfassungseinrichtung an die Leseeinrichtung, die ebeso eine Sende- und/oder eine Empfangseinrichtung hat, drahtlos überträgt.A laundry treatment device, in particular a tumble dryer, is provided with a housing, a drum rotatably disposed in the housing, one Measuring device for detecting at least one parameter of the drum laundry and / or the process medium conveyed by the drum In particular, the process air is used, the measuring device Measured value acquisition device and a reading device arranged on the housing includes. The measured value detection device is arranged on the drum and has one Transmitting and / or receiving device that the measured values of Measured value acquisition device to the reading device, which is also a transmitting and / or has a receiving device, transmits wirelessly.
Weiterhin ist bei der Wäschebehandlungsvorrichtung die Messwerterfassungseinrichtung an der Trommel angeordnet und die Leseeinrichtung regt die Messwerterfassungseinrichtung zur drahtlosen Übertragung der erfassten Messwerte an.Furthermore, the measured value detection device is in the laundry treatment device arranged on the drum and the reading device excites the Measured value acquisition device for wireless transmission of the acquired measured values.
Indem die Messwerterfassungseinrichtung an der Trommel angeordnet ist und die Leseeinrichtung die Messwerterfassungseinrichtung zur drahtlosen Übertragung der entsprechenden Meßwerte anregt, wird erreicht, dass die Messwerte in der Trommel erfasst werden, d. h. in einem Bereich, in dem es einen intensiven Kontakt mit der Wäsche gibt, so dass die erfassten Messwerte sehr genau sind. Weiterhin benötigt durch das Anregen der Messwerterfassungseinrichtung durch die Leseeinrichtung die Messwerterfassungseinrichtung keine eigene Energieversorgung, wie beispielsweise über eine Batterie oder über Schleifkontakte, wodurch die Messwerterfassungseinrichtung kompakt ausgebildet werden kann. Zudem entfällt die Wartung einer in der Messwerterfassungseinrichtung untergebrachten Energieversorgung, wie Wechsel der Batterien oder Wechsel der Schleifkontakte.In that the measured value detection device is arranged on the drum and the Reading device the measured value acquisition device for wireless transmission of stimulates corresponding measured values, it is achieved that the measured values in the drum are recorded, d. H. in an area where there is intensive contact with the Laundry there, so that the recorded measured values are very accurate. Still needed by the excitation of the measured value acquisition device by the reading device Measured value acquisition device does not have its own energy supply, such as via a battery or via sliding contacts, which makes the measured value acquisition device can be made compact. In addition, the maintenance of one in the Measured value acquisition device housed energy supply, such as changing the Batteries or change of sliding contacts.
Vorteilhafterweise kann somit bei jeder Trommelumdrehung die Meßwerterfassungseinrichtung mit einem Energieimpuls aus dem Lesegerät angeregt und dabei die erfaßten Meßwerte dem Lesegeräte drahtlos übertragen werden.Advantageously, the Measured value detection device excited with an energy pulse from the reader and the readings are transmitted wirelessly to the readers.
Sowohl die Energieübertragung als auch die Informationsübertragung erfolgt analog zur Transpondertechnologie mittels eines Schwingkreises. Dementsprechend überträgt in einer vorteilhaften Ausführung der Erfindung die Leseinrichtung drahtlos Energie an die Messwerterfassungseinrichtung, wobei die Messwerterfassungseinrichtung einen Energiespeicher bevorzugt einen Kondensator zur Speicherung der übertragenen Energie aufweist. Hierdurch wird eine einfache Anordnung zur Übertragung und Speicherung der Energie an die Messwerterfassungseinrichtung zur Verfügung gestellt.Both the transmission of energy and the transmission of information take place analogously to Transponder technology using an oscillating circuit. Accordingly transmits in an advantageous embodiment of the invention, the reading device wireless energy to the Measured value acquisition device, wherein the measured value acquisition device has a Energy storage preferably a capacitor for storing the transmitted energy having. This creates a simple arrangement for transferring and storing the Energy made available to the measured value acquisition device.

Prozessmedium erfassbar sind.In an advantageous embodiment of the invention, the measurement value acquisition device a temperature sensor and / or a moisture sensor and / or one Weight sensor, whereby all relevant measurement parameters of those in the drum Laundry and / or process air or process medium can be detected.
In einer vorteilhaften Ausführung der Erfindung sind die Messwerterfassungseinrichtung
und die Leseeinrichtung zueinander derart positioniert, dass bei jeder Umdrehung der
Trommel, die Messwerterfassungseinrichtung an der Leseinrichtung unter einem
vorbestimmten Abstand vorbeibewegt wird, wobei die Drehbewegung bzw. die Drehzahl
oder die Position der Trommel gegenüber der am Gehäuse angeordneten Leseinrichtung
erfasst wird und/oder Messdaten und/oder Energie zwischen
Messwerterfassungseinrichtung und Leseeinrichtung übertragen werden. Hierdurch ist es
nicht nur möglich, die Messdaten und die Energie effizient zu übertragen, da der
vorbestimmte Abstand so klein wie möglich ausgeführt wird, sondern auch eine
Information darüber zu gewinnen, mit welcher Drehzahl sich die Trommel dreht und/oder
ob sich die Trommel überhaupt noch dreht. Im Fall einer Drehzahl der Trommel, die
unterhalb einer kritischen Drehzahl liegt oder im Fall eines Stillstands der Trommel wird
auf einen Defekt des Trommelantriebs geschlossen, so dass in Folge dessen
Sicherheitsmaßnahmen eingeleitet werden, wie beispielsweise eine in der Vorrichtung
bzw. im Wäschetrockner vorgesehene Heizeinrichtung abzuschalten und/oder die
Fördermenge einer Prozessluft durch die Trommel fördernden Ventilatoreinrichtung zu
erhöhen, oder das Gerät abzuschalten.
Beim Erfassen von Messwerten, die für den Betrieb der Vorrichtung einen kritischen
Zustand oder eine Fehlfunktion darstellen, werden daher Maßnahmen zum sicheren
Betrieb ergriffen.In an advantageous embodiment of the invention, the measured value detection device and the reading device are positioned relative to one another in such a way that with each revolution of the drum, the measured value detection device is moved past the reading device at a predetermined distance, the rotational movement or the rotational speed or the position of the drum relative to that on the Housing arranged reading device is detected and / or measurement data and / or energy between measurement value acquisition device and reading device are transmitted. This makes it possible not only to transmit the measurement data and the energy efficiently since the predetermined distance is made as small as possible, but also to obtain information about the speed at which the drum is rotating and / or whether the drum is rotating at all still spins. In the event of a speed of the drum that is below a critical speed or in the event of a standstill of the drum, a defect in the drum drive is concluded, so that safety measures are initiated as a result, such as switching off a heating device provided in the device or in the tumble dryer and / or to increase the flow rate of a process air through the drum-promoting fan device, or to switch off the device.
When recording measured values that represent a critical state or a malfunction for the operation of the device, measures for safe operation are therefore taken.
