Abstract

Dryer has electronic measuring devices. Parameters registered by the measuring installations are evaluated by a microprocessor and the drying cycle is subsequently controlled. Dryer has a means to enable the operator to preselect the ending time of the drying process. Progress of the removal of moisture from the laundry is measured continuously and the data is fed to a microprocessor. Projected end time is calculated on the basis of the registered drying speed and a drying target pre-set by the operator. ADVANTAGE - In the programme controlled laundry dryer, drying process is brought to an end at a predetermined point in time with an optimum deg. of efficiency.

Description

Die Erfindung betrifft einen programmgesteuerten Wäschetrockner nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a program-controlled clothes dryer according to the Preamble of claim 1.

Es sind Wäschetrockner für den Haushaltsgebrauch bekannt, die mit einer sogenannten Startzeitvorwahl ausgerüstet sind. Eine solche Startzeitvorwahl erlaubt es, den Beginn des Trocknungsvorganges auf eine bestimmte Zeit festzulegen. Dadurch wird erreicht, daß beispielsweise günstige Nachtstromtarife ausgenutzt werden können. Weiterhin sind Wäschetrockner mit einem mechanischen oder elektrischen Zeitschalter bekannt, mit dem sich die voraussichtliche Trocknungsdauer durch die Bedienungsperson vorwählen läßt. Die einzustellende Trocknungsdauer erfordert aber bei der Bedienungsperson einen gewissen Kenntnisstand von Erfahrungswerten, die aber erst im Laufe der Zeit erworben werden. Da die Dauer eines Trocknungsvorganges von vielen Parametern, wie Wäschemenge, Wäscheart, Wäschezusammensetzung, Entfeuchtung, gewähltes Trocknungsziel, gewählte Heizleistung usw. abhängt, ist die Abschätzung der Trocknungsdauer für einen Wäscheposten sehr schwierig und damit oftmals ungenau.There are tumble dryers for household use, with a so-called start times are equipped. Such Delay start time allows the drying process to start to set a certain time. This ensures that, for example cheap night electricity tariffs can be used. Furthermore are Tumble dryer with a mechanical or electrical timer known with which the expected drying time by the Lets operator select. The drying time to be set but requires a certain level of knowledge of the operator Empirical values, which are only acquired over time. There the duration of a drying process of many parameters, such as Amount of laundry, type of laundry, laundry composition, dehumidification, selected Drying target, selected heating output etc. depends on the estimate the drying time for a lot of laundry very difficult and therefore often inaccurate.

Der Erfindung liegt die Aufgabe zugrunde, einen Wäschetrockner der in Rede stehenden Art so auszugestalten, daß ein Trocknungsvorgang zu einem bestimmten Zeitpunkt mit einem optimalen Wirkungsgrad beendet ist.The invention has for its object a dryer in Specified type to design that a drying process to a certain point in time has ended with an optimal efficiency.

Die Lösung dieser Aufgabe besteht nun darin, daß der Wäschetrockner mit Mitteln ausgestattet ist, durch die das Ende des Wäschetrocknungsvorganges zeitlich von der Bedienungsperson vorwählbar ist. Durch die Festlegung des Wäschetrocknungsvorgangendes durch die Bedienungsperson auf eine bestimmte Zeit ist es einer sogenannten intelligenten elektronischen Steuerung z. B., einem Microprozessor, möglich, den Trocknungsverlauf selbsttätig so zu steuern, daß innerhalb des zum Trocknen verfügbaren Zeitraumes ein optimales Trocknungsergebnis bei Berücksichtigung des günstigsten Energieverbrauchs usw. erreicht wird.The solution to this problem is that the dryer with Is equipped by means of which the end of the Laundry drying process can be preselected by the operator  is. By determining the laundry drying process end by the Operator at a certain time it is a so-called intelligent electronic control z. B., a microprocessor, possible to control the drying process automatically so that within of the period available for drying an optimal drying result achieved taking into account the cheapest energy consumption, etc. becomes.

Ein solcher Trocknungs-Vorgang läuft nun in der Weise ab, daß die Bedienungsperson beispielsweise morgens um 8.00 Uhr das Ende des Wäschetrocknungsvorganges auf 18.00 Uhr vorwählt bzw. festlegt, um dann ab diesem Zeitpunkt eine Nachbehandlung der Wäsche (beispielsweise bügeln oder mangeln) durchführen zu können. Die Festlegung des Wäschetrocknungsvorgangendes auf einen bestimmten Zeitpunkt hat nun den Vorteil, daß der für den Trocknungsvorgang zur Verfügung stehende Zeitraum optimal genützt werden kann, d. h. daß beispielsweise die Heizleistung, Luftmenge oder Wäschetrommelbewegung in Abhängigkeit von der zur Verfügung stehenden Trocknungszeit vom Microprozessor so berechnet und vorgegeben wird, daß ein optimaler Energieverbrauch sowie optimalste Wäscheschonung usw. erreicht wird. So wird beispielsweise bei einer verfügbaren Trocknungszeit von 4 Stunden der Trocknungsvorgang mit einer Heizleistung von 2000 Watt begonnen. Die fortschreitende Entfeuchtung der Wäsche wird dabei laufend mit Hilfe der üblichen elektronischen Meßverfahren (Leitwertmessung, Messung der elektrostatischen Aufladung der Wäsche, Temperaturdifferenzmessung) erfaßt und die Meßdaten dem Microprozessor zugeführt. Aus der von diesem ermittelten Trocknungsgeschwindigkeit und dem von der Bedienungsperson vorgewählten bzw. vorgegebenen Trocknungsziel (Wäsche schranktrocken, bügelfeucht oder mangelfeucht) ist es nun möglich, eventuell auch unter Zugrundelegung eines empirisch ermittelten gerätetypischen Trocknungsverlaufs, zunächst die voraussichtliche Trocknungsdauer u. damit Trocknungsendzeit zu errechnen. Aus der Differenz zwischen der errechneten Trocknungsendzeit und der zur Verfügung stehenden Trocknungszeit (hier vier Stunden) wird dann das Steuersignal für eine höhere oder eine niedrigere Heizleistung abgeleitet und entsprechende Schaltmaßnahmen veranlaßt. Such a drying process now takes place in such a way that the For example, the operator ends the morning of 8:00 a.m. Preselect or set the laundry drying process at 6:00 p.m. and then from this point in time, post-treatment of the laundry (for example ironing or ironing). The determination of the The laundry drying process at a certain time now has the Advantage that the available for the drying process Period can be used optimally, d. H. that for example the Heating output, air volume or washing drum movement depending on the drying time available from the microprocessor is calculated and specified that an optimal energy consumption as well optimal laundry protection etc. is achieved. For example, at the drying process with an available drying time of 4 hours a heating power of 2000 watts started. The progressive Dehumidification of the laundry is carried out continuously with the help of the usual electronic measuring methods (conductance measurement, measurement of electrostatic charging of the laundry, temperature difference measurement) detected and the measurement data supplied to the microprocessor. From that of this determined drying speed and that of the operator Preselected or predefined drying target (laundry dry in the cupboard, iron damp or insufficiently damp) it is now possible, possibly also under On the basis of an empirically determined device-typical Drying process, first the expected drying time u. to calculate the end of drying time. From the difference between the calculated drying time and the available Drying time (here four hours) then becomes the control signal for one derived higher or lower heating output and corresponding Switching measures initiated.  

In Weiterbildung der Erfindung wäre es auch denkbar, die voraussichtliche Trocknungsendzeit bzw. die Trocknungsdauer gleich zu Beginn des Trocknungsvorganges durch Ermittlung des jeweiligen Wäschebeladungsgewichtes zu errechnen und der Bedienungsperson zur Anzeige zu bringen. Für die Erkennung bzw. Errechnung der voraussichtlichen Trocknungsendzeit wird zweckmäßig die Entfeuchtung der Wäsche als Funktion der Zeit oder der Temperaturverlauf der die Wäschetrommel verlassenden Abluft über die Zeit oder die Temperaturdifferenzänderung zwischen Trommeleintritts- oder Trommelaustrittstemperatur oder die Dämpfung eines Hochfrequenzsignals als Funktion der Zeit oder die Kombination mehrerer dieser Maßnahmen zugrundegelegt. Die Differenz zwischen verfügbarer Trocknungszeit und voraussichtlicher Trocknungsdauer, die durch die jeweilige Parametereinstellung bestimmt ist, wird zweckmäßig laufend ermittelt. In Abhängigkeit von der ermittelten Differenz und unter Berücksichtigung der eingestellten Parameter wird z. B. die Heizleistung, Luftmenge oder Trommelbewegung so verändert, daß die verfügbare Trocknungszeit optimal ausgenutzt wird. Diese Anpassung kann dabei laufend vorgenommen werden.In a further development of the invention, it would also be conceivable that expected end of drying time or drying time Start the drying process by determining the respective To calculate laundry load weight and the operator Bring ad. For the detection or calculation of the The expected drying end time will be the dehumidification of the Laundry as a function of time or the temperature curve of the Exhaust air leaving the washing drum over time or Temperature difference change between drum entry or Drum outlet temperature or the damping of a Radio frequency signal as a function of time or a combination of several based on these measures. The difference between available Drying time and expected drying time by the the respective parameter setting is determined, is expediently ongoing determined. Depending on the determined difference and under Taking into account the set parameters, e.g. B. the heating power, Air volume or drum movement changed so that the available Drying time is optimally used. This adjustment can be done be made continuously.
