Bei diesen aus dem Stand der Technik bekannten Art der Beduftung von Wäschestücken während des Trocknungsvorganges kann es vorkommen, dass der Duftmittelträger bereits aufgebraucht ist, ohne dass es der Benutzer bemerkt. Der Trocknungsvorgang findet dann hierbei ohne Duftstoffzugabe statt, sodass eine zuverlässige Duftabgabe oder Duftverteilung in der Wäsche nicht sichergestellt ist.In these known from the prior art type of scenting laundry items during the drying process, it may happen that the fragrance carrier is already used up, without the user noticed. The drying process then takes place here without fragrance addition, so that a reliable fragrance delivery or fragrance distribution in the laundry is not guaranteed.

Der Erfindung liegt somit die Aufgabe zu Grunde, ein Verfahren zum Bertreiben eines Wäschetrockners mit einer Beduftung von Wäschestücken bereitzustellen, bei dem stets die gewünschte Beduftung auf einfache Weise und benutzerfreundlich sichergestellt ist.The invention is therefore based on the object to provide a method for Bertreiben a tumble dryer with a scent of laundry, in which always the desired scenting is ensured in a simple and user-friendly.
Erfindungsgemäß wird diese Aufgabe durch den unabhängigen Anspruch 1 gelöst, vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention this object is achieved by the
Die mit der Erfindung erreichten Vorteile bestehen nun darin, dass dem Benutzer eine zuverlässige Ausgabe einer Information ausgegeben wird, wenn der Duftmittelträger aufgebraucht oder zumindest die Gefahr besteht, dass der Duftmittelträger nicht mehr genügend Duftstoff für den nächstfolgenden Trocknungszyklus beinhaltet. Die Ausgabe erfolgt hierbei nicht erst dann, wenn es sozusagen zu spät ist und wirklich kein Duftstoff mehr im Duftmittelträger vorhanden ist, sondern anhand einer Plausibilitätsprüfung, die anhand von aufgezeichneten, mehreren durchgeführten Trocknungsprogrammen erfolgt. Die Plausibilitätsprüfung umfasst hierzu die Schritte
- Ermitteln einer Bedingung zur Identifikation eines aufgebrauchten Duftmittelträgers und
- Aktivieren eines Ausgabemittels, wenn die Bedingung erfüllt ist, dass ein aufgebrauchter Duftmittelträger identifiziert ist. Als aufgebrauchter Duftmittelträger wird hierbei das aufgebrauchte oder nicht mehr wirksame Duftmittel im Duftmittelträger verstanden. Insbesondere können als Duftmittelträger sogenannte Einwegkartuschen eingesetzt werden, die ebenfalls als aufgebraucht gelten, wenn das Duftmittel darin aufgebraucht ist.
- Determining a condition for identifying a depleted fragrance carrier and
- Activating a dispensing means when it is satisfied that a depleted fragrance carrier is identified. A depleted fragrance carrier is here understood to mean the depleted or no longer effective fragrance in the fragrance carrier. In particular, so-called disposable cartridges can be used as a fragrance carrier, which are also considered to be used up when the fragrance is used up therein.
Dadurch kann sehr zuverlässig aufgrund der tatsächlichen Bedingungen, die bei mehreren, nacheinander abgelaufenen Trocknungsprozessen aufgetreten sind, erfasst werden, wie viel Duftmittel verbraucht wurde und daraus abgeleitet, wie viel Duftmittel sich noch im Duftmittelträger befindet bzw. ob das noch im Duftmittelträger vorhandene Duftmittel für den aktuell eingestellten Trocknungszyklus ausreicht. Der Benutzer bekommt also vor oder nach dem Start, zumindest zu Beginn des Trocknungszyklus signalisiert, wenn die Duftmittelmenge nicht mehr ausreicht bzw. die gewünschte Beduftung nicht sichergestellt ist. Der Benutzer kann dann den Trocknungsprozess unterbrechen oder erst gar nicht starten und den Duftmittelträger gegen einen neuen austauschen oder mit Duftstoff wieder auffüllen. Anschließend kann der Trocknungszyklus gestartet oder fortgesetzt werden. Insgesamt ist es hierbei vorteilhaft, dass kein Sensor für die Erfassung des Befüllungszustandes des Duftmittelträgers notwendig ist.This can be very reliable due to the actual conditions that have occurred in several consecutively expired drying processes are detected how much fragrance was consumed and derived from how much fragrance is still in the fragrance carrier or whether the fragrance carrier still present in the fragrance carrier for the currently set drying cycle is sufficient. The user gets so before or after the start, at least at the beginning of the drying cycle signals when the amount of fragrance is no longer sufficient or the desired fragrance is not guaranteed. The user can then interrupt the drying process or not even start and exchange the fragrance carrier for a new or replenished with perfume. Subsequently, the drying cycle can be started or continued. Overall, it is advantageous in this case that no sensor is necessary for detecting the filling state of the fragrance carrier.
In einer Ausführung ist als Bedingung eine vorgegebene Dauer in Summe des aktivierten Gebläses mehrerer Trocknungszyklen festgelegt. Damit kann genauer die Aktivität der Beduftung erfasst werden. Beispielsweise wird hierbei berücksichtigt, dass der Duftmittelträger für weniger Trocknungszyklen aktivierbar ist, wenn sie jeweils eine längere Gebläseaktivität, beispielsweise jeweils von eineinhalb bis drei Stunden Dauer, beinhalten. Ferner kann die Kapazität des Duftmittelträgers für mehr Trocknungszyklen ausreichen, wenn es sich jeweils um kürzere Trocknungszyklen, beispielsweise nur um halbstündigeTrocknungszyklen handelt. Die Gesamtdauer der Gebläseaktivität ist auf die Kapazität des Duftmittelträgers ausgelegt, wobei es sich als zweckmäßig erwiesen hat, den Duftmittelträger so zu dimensionieren, dass die Gesamtdauer der Gebläseaktivität aus der Summe mehrerer Trocknungszyklen im Bereich von 20 und 100 Stunden festgelegt ist.In one embodiment, a predetermined duration is defined as the sum of the activated blower of several drying cycles as a condition. In this way, the activity of the scenting can be more accurately recorded. For example, it is taken into account here that the fragrance carrier can be activated for fewer drying cycles if they each contain a longer fan activity, for example of one and a half to three hours duration in each case. Further, the capacity of the fragrance carrier may be sufficient for more drying cycles, each being shorter drying cycles, for example only half an hour drying cycles. The total duration of the fan activity is designed for the capacity of the fragrance carrier, wherein it has proven to be expedient to dimension the fragrance carrier so that the total duration of the fan activity is determined from the sum of several drying cycles in the range of 20 and 100 hours.
In einer anderen vorteilhaften Weiterbildung ist als Bedingung eine vorgegebene Dauer in Summe der aktivierten Heizeinrichtung mehrerer Trocknungszyklen festgelegt. Hierbei wird das hitzebedingte Auflösungsverhalten des Duftstoffes mit berücksichtigt. So verhält es sich bei den meisten Duftstoffen derart, dass bei kalter Umgebungsluft, wie 15 bis 25°C eine langsamere Diffusion oder Verdunstung stattfindet, als bei warmer oder heißer Umgebungsluft, wie beispielsweise 50 bis 90 °C. Die Gesamtdauer der Heizungsaktivität ist auf die Kapazität des Duftmittelträgers ausgelegt, wobei es sich als zweckmäßig erwiesen hat, den Duftmittelträger so zu dimensionieren, dass die Gesamtdauer der Heizungsaktivität aus der Summe mehrerer Trocknungszyklen im Bereich von 20 und 100 Stunden festgelegt ist. Auch die Kombination der Gebläsedauer, Luftdurchsatz der Prozessluft und eingestellte Heizleistung wird in einer weiteren Ausführung mit berücksichtigt.In another advantageous development, a predetermined duration in sum of the activated heating device of several drying cycles is defined as a condition. Here, the heat-related dissolution behavior of the fragrance is taken into account. For most fragrances, for example, in cold ambient air, such as 15 to 25 ° C, slower diffusion or evaporation occurs than in warm or hot ambient air, such as 50 to 90 ° C. The total duration of the heating activity is based on the capacity of the Designed fragrance carrier, wherein it has proven to be expedient to dimension the fragrance carrier so that the total duration of the heating activity of the sum of several drying cycles is set in the range of 20 and 100 hours. The combination of the blower duration, air flow rate of the process air and set heating power is also taken into account in a further design.
In einer insgesamt zweckmäßigen Ausführung kann die vorgegebene Anzahl von Trocknungszyklen oder die vorgegebene Dauer des aktivierten Gebläses oder der aktivierten Heizeinrichtung mittels eines Eingabemittels eingestellt werden. Somit wird die Bedingung für die Identifikation eines aufgebrauchten Duftmittelträgers auf die Eigenschaften und Lebensdauer des jeweils eingesetzten Duftmittels eingestellt oder angepasst.In an overall expedient embodiment, the predetermined number of drying cycles or the predetermined duration of the activated blower or the activated heating device can be set by means of an input means. Thus, the condition for the identification of a spent fragrance carrier on the properties and life of the fragrance used in each case is set or adjusted.
Insgesamt ist es vorteilhaft, dass als Ausgabemittel eine optische Anzeige, wie LED oder Symbol - oder Textausgabe auf einem Display eingesetzt oder verwendet wird. Damit können bereits vorhandene Anzeigemittel auf der Bedienblende des Trockners für diese Informations-oder Warnausgabe verwendet werden.Overall, it is advantageous that an optical display, such as LED or symbol or text output is used or used as a display on a display. Thus existing display means can be used on the control panel of the dryer for this information or warning output.
Zusätzlich oder alternativ kann auch eine akustische Ausgabe der Warnmeldung für einen leeren oder aufgebrauchten Duftmittelträger verwendet werden.Additionally or alternatively, an acoustic output of the warning message for an empty or spent fragrance carrier can be used.
In einer zweckmäßigen Weiterbildung des erfindungsgemäßen Verfahrens werden weitere Schritte durchgeführt:
- Auffüllen oder Auswechseln des Duftmittelträgers;
- Zurücksetzen oder Löschen der Bedingung für die Identifikation eines aufgebrauchten Duftmittelträgers und
- Deaktivieren des Ausgabemittels.
- Filling or replacing the fragrance carrier;
- Resetting or deleting the condition for the identification of a depleted fragrance carrier and
- Disabling the output device.
Damit wird der Zähler für die Gesamtzeiten oder Zyklenanzahl auf einen Initialwert Null gesetzt und die Erfassung beginnt von neuem.This sets the Total Time or Number of Cycles counter to an initial value of zero and acquisition begins again.
In einer einfach bereitzustellenden Ausführung erfolgen das Zurücksetzen der besagten Bedingung und das Deaktivieren des Ausgabemittels mittels einer manuellen Bedienhandhabe.In an easily provided embodiment, the resetting of the said condition and the deactivation of the output means take place by means of a manual operating handle.
In einer etwas komfortableren Ausführung erfolgt das Zurücksetzen der besagten Bedingung und das Deaktivieren des Ausgabemittels selbständig beim Einsetzen des Duftmittelträgers in eine vorgegebene, betriebsgemäße Position. Hierbei werden Fehlbedienungen, beispielsweise durch Vergessen des manuellen Zurücksetzens der Bedingung, nahezu gänzlich oder gänzlich vermieden. Der Wechsel des Duftmittelträgers kann hierbei mittels eines Mikroschalters, einer berührungslosen Sensoranordnung oder einer anderen Kopplung mit der Steuereinrichtung erfasst werden.In a somewhat more comfortable embodiment, the resetting of the said condition and the deactivation of the dispensing means occur automatically when the fragrance carrier is inserted into a predetermined, operative position. In this case, incorrect operation, for example, by forgetting the manual reset of the condition, almost completely or completely avoided. The change of the fragrance carrier can in this case be detected by means of a microswitch, a contactless sensor arrangement or another coupling with the control device.
