Description
Die Erfindung betrifft einen Haushaltswäschetrockner und ein Verfahren zum Erkennen einer Drehbewegung einer mittels eines Motors drehbaren Trommel eines Haushaltswäschetrockners der im Oberbegriff der Patentansprüche 1 bzw. 11 angegebenen Art.The invention relates to a household laundry dryer and a method for detecting a rotational movement of a rotatable drum of a motor drum of a household laundry dryer specified in the preamble of claims 1 and 11, respectively.
Bei derartigen, ganz allgemein beispielsweise aus der
Aus diesem Grund sind bei heute üblichen Haushaltswäschetrocknern Einrichtungen vorgesehen, mit denen eine Drehbewegung respektive ein Stillstand der Trommel erkannt werden kann (siehe z.B. das Dokument
Aufgabe der vorliegenden Erfindung ist es, einen Haushaltswäschetrockner sowie ein Verfahren zum Erkennen einer Drehbewegung einer Trommel der eingangs genannten Art so zu verbessern, dass auf baulich einfache Weise eine überwiegende Zahl von zum Stillstand der Trommel führenden Fehlerfällen ermittelt werden können.Object of the present invention is to improve a household tumble dryer and a method for detecting a rotational movement of a drum of the type mentioned so that a structurally simple manner, a vast number of leading to a standstill of the drum error cases can be determined.
Diese Aufgabe wird erfindungsgemäß durch einen Haushaltswäschetrockner und ein Verfahren zum Erkennen einer Drehbewegung einer Trommel mit den Merkmalen der Patentansprüche 1 bzw. 11 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen beschrieben.This object is achieved by a household laundry dryer and a method for detecting a rotational movement of a drum with the features of claims 1 and 11, respectively. Advantageous embodiments with expedient and non-trivial developments of the invention are described in the remaining claims.
Bei dem Haushaltswäschetrockner nach der Erfindung umfasst die Einrichtung zum Erkennen einer Drehbewegung bzw. eines Stillstandes der Trommel einen kapazitiven Sensor, dessen erster leitfähiger Belag an einem bei der Drehbewegung der Trommel mitdrehenden Teil und dessen zweiter leitfähiger Belag gegenüber dem ersten Belag ortsfest angeordnet ist. Mit anderen Worten bilden die beiden leitfähigen Beläge einen elektrischen Kondensator, dessen erster leitfähiger Belag entsprechend der Drehbewegung der Trommel mitgedreht und dessen zweiter leitfähiger Belag demgegenüber an Ort und Stelle verbleibt. Die beiden leitfähigen Beläge sind dabei so an dem mit der Trommel mitdrehenden Teil bzw. demgegenüber ortsfest angeordnet, dass sich zwischen den beiden Belägen ein das isolierende Dielektrikum bildender Spalt ausbildet.In the household laundry drier according to the invention, the device for detecting a rotational movement or a standstill of the drum comprises a capacitive sensor, the first conductive pad is fixedly arranged on a co-rotating during the rotation of the drum part and the second conductive pad against the first pad. In other words, the two conductive pads form an electrical capacitor whose first conductive pad rotates according to the rotational movement of the drum and the second conductive pad remains in place on the other hand. In this case, the two conductive coverings are arranged so as to be stationary on the part rotating with the drum or, in contrast, in such a way that a gap forming the insulating dielectric is formed between the two coverings.
Beim hierzu erfindungsgemäß vorgesehenen Verfahren zum Erkennen einer Drehbewegung der Trommel wird dabei die Kapazität des durch den ersten und zweiten leitfähigen Belag gebildeten kapazitiven Sensors ermittelt. Hierbei wird dem Umstand Rechnung getragen, dass die Trommel bedingt durch konstruktionsbedingte Unregelmäßigkeiten wie Falze, Schweißnähte und Prägungen sowie fertigungstechnische Toleranzen naturgemäß eine gewisse Unwucht aufweist und sich demgemäß der Abstand und die Überschneidung der beiden leitfähigen Beläge im Verlauf der Drehbewegung der Trommel ändern. Die hierdurch im Verlauf der Drehbewegung der Trommel entstehende Kapazitätsänderung kann dabei auf äußerst einfache Weise erfasst werden.When inventively provided for detecting a rotational movement of the drum, the capacitance of the capacitive sensor formed by the first and second conductive coating is determined. Here, the fact is taken into account that the drum caused by design-related irregularities such as folds, welds and embossing and manufacturing tolerances naturally has a certain imbalance and accordingly change the distance and the overlap of the two conductive pads in the course of rotation of the drum. The resulting in the course of the rotational movement of the drum capacitance change can be detected in a very simple manner.
Im Unterschied zu bekannten Fliehkraftschaltern an der Antriebswelle - welche beispielsweise einen Riss des Antriebsriemens nicht erfassen können - und Riemenrissschaltern -welche beispielsweise einen durchrutschenden Antriebsriemen nicht erkennen - ermöglicht der erfindungsgemäße Einsatz eines kapazitiven Sensors unmittelbar an einem bei der Drehbewegung der Trommel mitdrehenden Teil die Erfassung annähernd aller Fehlerfälle, die zu einem Stillstand der Trommel während des Trockenvorgangs führen können. Dabei erfolgt die Messung auf besonders einfache und zuverlässige Weise.In contrast to known centrifugal force switches on the drive shaft - which can not detect, for example, a crack of the drive belt - and belt breakers - which, for example, do not recognize a slipping drive belt - allows the inventive use of a capacitive sensor directly on a co-rotating during the rotation of the drum part, the detection approximately all faults that can lead to a standstill of the drum during the drying process. The measurement is carried out in a particularly simple and reliable manner.
So hat es sich beispielsweise als insbesondere vorteilhaft gezeigt, den ersten leitfähigen Belag am Außenumfang eines Trommelhalses oder der Trommel selbst auszubilden. Der kapazitive Sensor kann hierdurch insgesamt sehr einfach aufgebaut sein, wobei die Erkennung der Drehbewegung bzw. des Stillstandes der Trommel - beispielsweise im Unterschied zu einem Fliehkraftschalter an der Antriebswelle - unmittelbar an der Trommel selbst durchgeführt werden kann. Eine besonders einfache Gestaltung des ersten leitfähigen Belages kann dadurch erreicht werden, dass dieser unmittelbar durch die Außenumfangsfläche der Trommel bzw. des Trommelhalses gebildet wird. Erfahrungsgemäß besteht zumindest der Trommelhals in den allermeisten Fällen aus einem leitfähigen Metall und ist normalerweise gut geerdet, so dass sich die Außenumfangsfläche des Trommelhalses auf besonders gute Weise für die Bildung eines Kondensators eignet.For example, it has proven particularly advantageous to form the first conductive coating on the outer circumference of a drum neck or the drum itself. The capacitive sensor can thereby be constructed very simple overall, the detection of the rotational movement or the standstill of the drum - for example, in contrast to a centrifugal switch on the drive shaft - can be performed directly on the drum itself. A particularly simple design of the first conductive coating can be achieved in that it is formed directly by the outer peripheral surface of the drum or the drum neck. Experience has shown that at least the drum neck in the vast majority of cases consists of a conductive metal and is normally well grounded, so that the outer peripheral surface of the drum neck is particularly well suited for the formation of a capacitor.
Als weiter vorteilhaft hat es sich gezeigt, den ersten leitfähigen und mit der Trommel mitdrehenden Belag als am Außenumfang der Trommel bzw. des Trommelhalses vollständig umlaufender Ringbelag auszubilden. Hierdurch kann während der gesamten Umdrehung der Trommel die Kapazitätsänderung des kapazitiven Sensors ermittelt werden. Gleichfalls wäre es natürlich auch denkbar, den ersten leitfähigen Belag nur bereichsweise am Außenumfang der Trommel anzuordnen. So wäre es beispielsweise denkbar, den ersten leitfähigen Belag lediglich an einem Viertel oder der Hälfte des Außenumfangs vorzusehen. Dabei wäre es natürlich auch denkbar, dass der leitfähige Belag von einem von der Trommel oder dem Trommelhals separaten Teil gebildet wird, welches dann beispielsweise über eine Klebverbindung am Außenumfang der Trommel bzw. des Trommelhalses fixiert wird.As a further advantage, it has been shown to form the first conductive and co-rotating with the drum pad as the outer circumference of the drum or the drum neck completely circumferential annular coating. This can during the entire revolution of the drum, the capacitance change of the capacitive sensor can be determined. Likewise, it would of course also conceivable to arrange the first conductive coating only in regions on the outer circumference of the drum. For example, it would be conceivable to provide the first conductive coating only on a quarter or half of the outer circumference. It would of course also conceivable that the conductive coating is formed by a separate from the drum or the drum neck part, which is then fixed, for example via an adhesive bond on the outer circumference of the drum or the drum neck.
Bei der Durchführung des erfindungsgemäßen Verfahrens hat es sich zudem als vorteilhaft gezeigt, die Kapazitätsänderungen des kapazitiven Sensors über eine vorbestimmte Zeitdauer zu ermitteln. Hierdurch wird eine besonders sichere Erkennung eines Trommelstillstandes ermöglicht. Wird während dieser vorbestimmten Zeitdauer keine Kapazitätsänderung ermittelt, so wird ein Signal beispielsweise zum Abschalten einer Heizung und/oder des Motors erzeugt.In carrying out the method according to the invention, it has also proven to be advantageous to determine the capacitance changes of the capacitive sensor over a predetermined period of time. This allows a particularly secure detection of a drum standstill. If no change in capacitance is determined during this predetermined period of time, then a signal is generated, for example, to switch off a heater and / or the motor.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung; diese zeigt:
- Eine schematische Schnittansicht durch einen Haushaltswäschetrockner mit einer mittels eines Motors drehbaren Trommel und einer Einrichtung zum Erkennung der Drehbewegung der Trommel.
- Von einem Haushaltswäschetrockner ist in der Figur im Wesentlichen ein
Gehäuse 10 mit einer Ober- und Unterseite sowie einervorderen Stirnseite 12 und einerRückseite 14 erkennbar. Innerhalb des Haushaltswäschetrockners ist einedrehbare Trommel 16 angeordnet, welche mit einerTrommelwelle 18 und einer fest mit derRückseite 14 verbundenen Wellenbuchse 20 - um die Trommelachse T drehbar - gehalten ist. An ihrem dervorderen Stirnseite 12 zugeordneten Ende ist dieTrommel 16 außerdem über einTrommellagerrad 22 gehalten. Zum Drehantrieb der Trommel 16 ist einMotor 24 vorgesehen, der ein mit einemAntriebsriemen 26 in Eingriffstehendes Zahnrad 28 dreht. Hierzu steht derAntriebsriemen 26 mit einer am Außenumfang derTrommel 16 vorgesehenen und nicht dargestellten Zahnung im Eingriff. - Über eine
Beschickungstür 30 in derStirnseite 12 desGehäuses 10 kann die Trommel mit nassem Trockengut befüllt. Während des Trockenvorgangs wird dieTrommel 16 bzw. das sich darin befindende Trockengut mit einem Luftstrom beaufschlagt, der über einGebläse 32 erzeugt wird. DasGebläse 32 ist im vorliegenden Ausführungsbeispiel innerhalb einesAuslasskanals 34 nahe derStirnseite 12 desGehäuses 10 angeordnet. In einem Einlasskanal 36 nahe derRückseite 14 desGehäuses 10 ist eineHeizung 38 angeordnet, mit welcher der durch dieTrommel 16 bzw. das Trockengut strömende Luftstrom erwärmt werden kann. Der Trockenvorgang ist über eineProgrammsteuerung 40 steuerbar, welche mit einerBedieneinheit 42 in Kontakt steht.
- A schematic sectional view through a household laundry dryer with a drum rotatable by a motor and means for detecting the rotational movement of the drum.
- From a household tumble dryer in the figure, a
housing 10 with a top and bottom and afront end face 12 and arear side 14 is substantially recognizable. Within the household tumble dryer, arotatable drum 16 is arranged, which is held with adrum shaft 18 and a firmly connected to theback 14 shaft bushing 20 - rotatable about the drum axis T. At itsfront end 12 associated end of thedrum 16 is also held on a drum bearingwheel 22. For the rotary drive of thedrum 16, amotor 24 is provided which one with aDrive belt 26 engagedgear 28 rotates. For this purpose, thedrive belt 26 is provided with a provided on the outer circumference of thedrum 16 and not shown teeth in engagement. - About a
feed door 30 in theend face 12 of thehousing 10, the drum can be filled with wet dry material. During the drying process, thedrum 16 or the dry matter therein is subjected to an air flow, which is generated by ablower 32. Thefan 32 is arranged in the present embodiment within anoutlet channel 34 near theend face 12 of thehousing 10. In an inlet channel 36 near theback 14 of thehousing 10, aheater 38 is arranged, with which the air flow flowing through thedrum 16 and the dry material can be heated. The drying process can be controlled via aprogram control 40, which is in contact with anoperating unit 42.
Damit eine unerwünschte Unterbrechung der Drehbewegung der Trommel 16 bzw. ein Stillstand - beispielsweise aufgrund eines Schadens des Motors 24, eines Reißens oder Durchrutschens des Antriebsriemens 26 oder eines Blockierens der Trommel 16 - ermittelt werden kann, ist eine Einrichtung 44 zum Erkennen der Drehbewegung der Trommel 16 nahe der Rückseite 14 des Gehäuses 10 vorgesehen. Diese Einrichtung 44 umfasst einen kapazitiven Sensor 45, dessen erster leitfähiger Belag 46 am Außenumfang eines Trommelhalses 50 der Trommel 16 ausgebildet ist. Im vorliegenden Ausführungsbeispiel ist der dem Trommelhals 50 zugeordnete erste leitfähige Belag 46 durch die Außenumfangsfläche des Trommelhalses 50 selbst gebildet. Hierzu ist der Trommelhals 50 aus einem leitfähigen Metall gestaltet, wobei der Trommelhals 50 in üblicher Weise geerdet ist. Außerdem ist im vorliegenden Ausführungsbeispiel der erste Belag 46 als am Außenumfang des Trommelhalses 50 vollständig umlaufender Ringbelag ausgebildet. Gleichfalls wäre es natürlich auch denkbar, dass sich der erste Belag 46 lediglich über eine Teillänge am Außenumfang des Trommelhalses 50 erstreckt. Außerdem wäre es auch denkbar, den ersten Belag 46 als separates Teil auszubilden und beispielsweise mittels einer Klebverbindung an dem Trommelhals 50 zu befestigen. Dem um den Trommelhals 50 umlaufenden ersten leitfähigen Belag 46 gegenüberliegend ist ein zweiter leitfähiger Belag 48 mittels eines Tragteils 52 am Gehäuse 10 und gegenüber dem ersten leitfähigen Belag 46 ortsfest angeordnet. Der zweite leitfähige Belag 48 ist im vorliegenden Ausführungsbeispiel von einem kleinen Plattenteil gebildet, welches im Wesentlichen flächenparallel zum Außenumfang des Trommelhalses 50 angeordnet ist. Die beiden leitfähigen Beläge 46, 48 sind dabei in einem derartigen Abstand zueinander angeordnet, dass ein Spalt entsteht, welcher das isolierende Dielektrikum zwischen den beiden Belägen 46, 48 des kapazitiven Sensors 45 bildet. Das Dielektrikum besteht demgemäß im vorliegenden Ausführungsbeispiel aus der innerhalb des Haushaltswäschetrockners vorliegenden Umgebungsluft.In order that an unwanted interruption of the rotational movement of the
Zwischen dem zweiten leitfähigen Belag 48 und dem Tragteil 52 ist eine im vorliegenden Ausführungsbeispiel nicht gezeigte Isolation vorgesehen. Als im Rahmen der Erfindung mit umfasst ist es zu betrachten, dass anstelle des hier vorgesehenen einen kapazitiven Sensors 45 natürlich auch mehrere am Außenumfang des Trommelhalses 50 angeordnet sein können. Dies wäre im vorliegenden Ausführungsbeispiel einfach dadurch zu verwirklichen, dass eine Mehrzahl von zweiten leitfähigen Belägen 48 gegenüber dem Außenumfang des Trommelhalses 50 verteilt angeordnet werden.Between the second
Wird nun die Trommel 16 gedreht, so entstehen am Trommelhals 50 aufgrund von fertigungsbedingten Toleranzen Unwuchten im Bereich seines Außenumfangs, so dass sich der Abstand und die Überschneidung der beiden leitfähigen Beläge 46, 48 während der Drehbewegung der Trommel 16 permanent ändert. Diese Kapazitätsänderung kann durch eine geeignete Messeinrichtung 54 erfasst werden, welche über Messleitungen 56, 58 mit dem ersten und zweiten Belag 46, 48 verbunden ist. Wird nun aufgrund eines Fehlerfalls die Drehbewegung der Trommel 16 unterbrochen bzw. steht diese still, so wird demgemäß über die Messeinrichtung 54 keine Kapazitätsänderung mehr erfasst. Hierzu wird die Kapazität über einen gewissen Zeitraum durch die Messeinrichtung 54 ermittelt und überprüft, ob eine Kapazitätsänderung vorliegt bzw. ob die Kapazität des Sensors 45 von einem vorbestimmten Wert über den vorbestimmten Zeitraum nicht abweicht. Wird über die Messeinrichtung 54 demgemäß keine Kapazitätsänderung des Sensors 45 und somit ein Trommelstillstand festgestellt, so kann beispielsweise über eine Signalleitung 60 ein Störungssignal an die Programmsteuerung 40 gemeldet werden. Über die Programmsteuerung 40 ist dann gegebenenfalls der Motor 24, das Gebläse 32 sowie die Heizung 38 abschaltbar, damit weitere Schäden innerhalb des Haushaltswäschetrockners wirksam vermieden werden können.If the
