Abstract

The controls (3 to 9 and 17) in a control screen (1) are provided for the input of individual functions of an individual operating program flow, said functions being filed in a memory. The operating program flow can be initiated under a name and can run according to order in a microprocessor guided manner. The controls also serve to adjust defined operating program sequences or defined parameter values of program functions and, in addition, can serve as a code for defined update functions in one or more defined sequences of function input.

Description

Programmgesteuertes HaushaltgerätProgram-controlled household appliance
Die Erfindung betrifft ein programmgesteuertes Haushaltgerät mit einer Bedienblende, in der Handhaben zur Eingabe einzelner Funktionen eines individuellen Betriebsprogrammablaufes, der unter einem Namen aufgerufen werden und mikroprozessorgeführt ordnungsgemäß ablaufen kann, angeordnet sind, und mit einem Speicher für unterschiedliche Funktionen dieses Programmablaufs.The invention relates to a program-controlled household appliance with an operating panel, in which handles for entering individual functions of an individual operating program sequence, which can be called under a name and can run properly under microprocessor control, are arranged, and with a memory for different functions of this program sequence.
Ein derartiges Haushaltgerät ist beispielsweise aus DE 44 22 128 A1 bekannt. Darin ist eine An- passung der werksseitigen Programmvorgaben an Kundenwünsche dadurch möglich, daß die elektronische Steuerung über eine Datenein- und -ausgabeeinheit mit einem Display frei programmierbar ist. Dazu müssen auf nicht näher erläuterte Weise weitere Daten bzw. Parameter eingegeben werden, damit die vorhandenen Programmvorgaben variiert bzw. ergänzt werden können. Da Angaben über die Art und Weise der Eingaben fehlen, sind gemäß anderen bekann- ten Haushaltgeräten dieser Art zusätzliche Eingabehandhaben vorzusehen, die für den Aufruf abgespeicherter Programmvorgaben ansich nicht nötig sind. Außerdem ist ein Display für die bekannte Einrichtung erforderlich.Such a household appliance is known for example from DE 44 22 128 A1. This allows the factory program specifications to be adapted to customer requirements in that the electronic control is freely programmable via a data input and output unit with a display. For this purpose, further data or parameters must be entered in a manner that is not explained in detail so that the existing program specifications can be varied or supplemented. Since information about the type of input is missing, additional input handles are to be provided according to other known household appliances of this type which are not actually necessary for calling up stored program specifications. A display is also required for the known device.
Weiterhin sind Waschmaschinen bekannt, in deren Bedienblenden ebenfalls Handhaben zum Einstellen von bestimmen Programmfunktionen angeordnet sind. Logische Verknüpfungen der Bedienung dieser Handhaben sind darin so eingerichtet, daß eingeweihte Personen (z.B. Kundendiensttechniker) durch Eingabe eines Codes von bestimmten Bedienungshandlungen, nämlich die Reihenfolge der Betätigung einzelner Bedienungshandhaben, bestimmte Funktionen oder bestimmte Kundendienst-Programme aufrufen können, deren Verlauf dem Kundendiensttechniker bei der Beobachtung der Waschmaschine Aufschlüsse über deren ordnungsgemäßen Betriebsprogrammablauf geben kann, dessen Ablauf seinerseits nämlich für die nötige Beobachtung zu lange dauern würde. Andererseits können durch geeignete Codierungen sogenannte Demonstrationsprogramme aufgerufen werden, bei denen ein bestimmter Betriebsprogrammablauf der Maschine simuliert wird, ohne daß Funktionselemente der Waschmaschine tatsäch- lieh betrieben werden. Dadurch sind installierte Programmabläufe an der Bedienblende der Waschmaschine demonstrierbar.Washing machines are also known, in whose control panels also handles for setting certain program functions are arranged. Logical links for the operation of these handles are set up in such a way that initiated persons (e.g. customer service technicians) can call certain functions or certain customer service programs by entering a code of certain operating actions, namely the sequence of the operation of individual operating handles, the course of which the customer service technician can call Observation of the washing machine can provide information about its proper operating program sequence, the sequence of which in turn would take too long for the necessary observation. On the other hand, so-called demonstration programs can be called up by means of suitable codings, in which a certain operating program sequence of the machine is simulated without functional elements of the washing machine actually being be operated. This means that installed program sequences can be demonstrated on the control panel of the washing machine.
Ferner sind Waschmaschinen bekannt, deren mikroprozessorgesteuerte Programmsteuerungseinrichtung über einen Datenbus an eine äußere Schnittstelle geführt sind, an die von außen über eine Busleitung ein Computer (z.B. ein Laptop) anschließbar ist, um bestimmte Veränderungen im installierten Programm des Mikrocomputers vorzunehmen, z.B. Änderungen an Programmsequenzen oder an Parameterwerten des betreffenden Programmablaufs. Nachteil solcher sogenannter Update-Funktionen ist die Notwendigkeit, für Änderungen in installierten Programmen einen großen Aufwand an Ausrüstungsgegenständen mitzuführen (z.B. Computer und Zubehör), zumal sich Update-Handlungen in der Regel auf kurze und geringfügige Änderungen beziehen.Furthermore, washing machines are known whose microprocessor-controlled program control devices are led via a data bus to an external interface to which a computer (e.g. a laptop) can be connected externally via a bus line in order to make certain changes in the installed program of the microcomputer, e.g. Changes to program sequences or to parameter values of the relevant program sequence. The disadvantage of such so-called update functions is the need to carry a large amount of equipment (e.g. computers and accessories) for changes in installed programs, especially since update actions usually relate to short and minor changes.
Der Erfindung liegt die Aufgabe zugrunde, bei einem eingangs bezeichneten Haushaltgerät eine Bedienungshandlung vorzusehen, die geeignet ist, entsprechende Update-Funktionen vorzunehmen, ohne dazu aufwendige Gerätschaften benutzen bzw. für den Aufruf abgespeicherter Pro- grammvorgaben nicht erforderliche, zusätzliche Bedienungshandhaben vorsehen zu müssen.The invention is based on the object of providing an operating action in a household appliance referred to at the outset which is suitable for carrying out corresponding update functions without having to use complex equipment for this purpose or having to provide additional operating handles which are not necessary for calling up stored program specifications.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine oder mehrere bestimmte Reihenfolgen von Funktionseingaben als Code für die Einstellung bestimmter Betriebsprogrammsequenzen bzw. bestimmter Parameterwerte von Programmfunktionen dienen. Dadurch sind eingeweihte Personen in der Lage, durch eine bestimmte Reihenfolge von Bedienungshand- lungen an den in der Bedienblende vorgesehenen und ohnehin erforderlichen Handhaben Veränderungen an einmal installierten Programmsequenzen oder Programmparametern vorzunehmen. Bei Bedienungsblenden, in denen auch ein Anzeigedisplay in Form einer alphanumerischen Anzeige vorgesehen ist, lassen sich solche Eingabehandlungen auch kontrollieren.According to the invention, this object is achieved in that one or more specific sequences of function inputs serve as code for the setting of certain operating program sequences or certain parameter values of program functions. As a result, initiated persons are able to make changes to program sequences or program parameters that have already been installed by means of a certain sequence of operating actions on the manipulations provided and required in any case in the control panel. In the case of control panels in which a display in the form of an alphanumeric display is also provided, such input operations can also be checked.
In einer vorteilhaften Ausführungsform der Erfindung für Wasch- oder Geschirrspülmaschinen können die Parameterwerte den Wasserstand im Laugenbehälter, die Temperatur der Lauge, sowie die Takte und die Zeitdauer für bestimmte Behandlungsschritte während des Betriebsprogrammablaufes betreffen. Eine weitere vorteilhafte Ausbildung der Erfindung in einer Waschoder Geschirrspülmaschine bestimmt als Programmsequenzen die Reihenfolgen von Wasserzulauf, Laugenheizung, Trommelbewegung, Laugenumwälzen und Abpumpen der Lauge. In ähnlicher Weise können bei einem Wäschetrockner die Parameterwerte die Temperatur derIn an advantageous embodiment of the invention for washing machines or dishwashers, the parameter values can relate to the water level in the tub, the temperature of the tub, as well as the cycles and the duration for certain treatment steps during the operating program sequence. Another advantageous embodiment of the invention in a washing machine or dishwasher determines as program sequences the sequences of water supply, lye heating, drum movement, lye circulation and pumping out of the lye. Similarly, in a tumble dryer, the parameter values can change the temperature of the
Prozeßluft, die Takte und die Zeitdauer für bestimmte Behandlungsschritte und die Restfeuchte der Wäsche betreffen. In bezug auf die Programmsequenzen können bei einem Wäschetrockner die Eingriffe die Reihenfolgen von Trommelbewegungen, Prozeßluftförderung, Kühlluftförderung und Kondensatabführung betreffen. Die Reihenfolge von Funktionseingaben kann in einer weiteren Fortbildung der Erfindung auch durch einen Drehwahlschalter als Bedienungshandhabe erfolgen, der zur Eingabe des Codes in unterschiedliche Drehpositionen stellbar ist. Zur Quittierung der Eingabe in der betreffenden Drehposition kann beispielsweise die zusätzliche Betätigung einer ohnehin in der Bedienungs- blende vorhandenen Taste für eine beliebige Funktion oder eine Push-Funktion am Drehwahlschalter selbst dienen.Process air, the cycles and the time for certain treatment steps and the residual moisture of the laundry concern. With regard to the program sequences, the interventions in a tumble dryer can relate to the sequences of drum movements, process air delivery, cooling air delivery and condensate removal. In a further development of the invention, the sequence of functional entries can also be made using a rotary selector switch as an operating handle, which can be set to different rotary positions for entering the code. To confirm the entry in the relevant rotary position, for example, the additional actuation of a button that is already present in the control panel for any function or a push function on the rotary selector switch itself can be used.
Anhand einer in der Zeichnung dargestellten Bedienblende für eine Waschmaschine ist die Erfindung nachstehend erläutert.The invention is explained below on the basis of a control panel for a washing machine shown in the drawing.
Die rechts neben der Griffschale 2 für eine Waschmittelschublade der nicht dargestellten Wasch- maschine angeordnete Bedienungsblende 1 enthält mehrere Bedienungs-Handhaben, nämlich einen Drehwahlschalter 3 und sechs Tasten 4 bis 9. Über den Tasten 4 bis 9 sind zur Quittierung der Betätigung LEDs 10 bis 15 vorgesehen, während ein alphanumerisches Anzeigedisplay 16 oberhalb eines zur Einstellung beispielsweise von Drehzahlwerten dienenden Drehwahlschalters 17 zur Darstellung von Parameterwerten (z.B. von Drehzahlwerten) geeignet ist. Die Ta- ste 18 dient ausschließlich zur Ein- bzw. Ausschaltung der elektronischen Steuerung und damit der gesamten Waschmaschine.The control panel 1 arranged to the right of the handle shell 2 for a detergent drawer of the washing machine (not shown) contains a number of operating handles, namely a rotary selector switch 3 and six keys 4 to 9. LEDs 10 to 15 are above the keys 4 to 9 to acknowledge the actuation provided, while an alphanumeric display 16 above a rotary selector 17 used for setting, for example, speed values is suitable for displaying parameter values (eg speed values). The button 18 is used only to switch the electronic control on and off and thus the entire washing machine.
Hinter der Bedienungsblende 1 ist bekanntermaßen eine elektronische Platine angeordnet (nicht dargestellt), auf der mehrere elektronische Bauelemente durch Leiterbahn-Kaschierung der Platine untereinander verbunden sind. Unter solchen elektronischen Bauelementen befinden sich regelmäßig auch Mikroprozessoren, Speicherbausteine, Schalter und ähnliches. Die durch dieAs is known, an electronic circuit board is arranged behind the control panel 1 (not shown), on which a plurality of electronic components are connected to one another by means of conductor lamination of the circuit board. Such electronic components regularly include microprocessors, memory chips, switches and the like. The through the
Bedienungshandhaben 3 bis 9 und 17 möglichen Funktionseingaben werden durch solche Mikroprozessoren und Speicherbausteine erfaßt und dienen in der Regel dazu, bestimmte Betriebsprogrammsequenzen und Parameterwerte für ein anschließend ablaufendes Programm festzulegen. Solche Programmsequenzen und Parameterwerte sind durch herstellerseitige In- stallation in der Programmsteuerungs-Elektronik festgelegt.Operating handles 3 to 9 and 17 possible functional inputs are recorded by such microprocessors and memory modules and are generally used to determine certain operating program sequences and parameter values for a program which is then to run. Such program sequences and parameter values are defined by the manufacturer's installation in the program control electronics.
Gemäß der Erfindung kann eine eingeweihte Person (z.B. ein Kundendiensttechniker) durch Eingabe einer bestimmten Reihenfolge von Funktionen an den Bedienungshandhaben bestimmte Betriebsprogrammsequenzen bzw. bestimmte Parameterwerte von Programmfunktionen verändern. Beispielsweise kann er eine bestimmte Reihenfolge von Tastenbedienungen vollführen, um die Zeitdauer einer Waschphase zu beeinflussen oder um die Temperatur der Lauge für eine bestimmte Programmsequenz nach unten oder nach oben zu korrigieren. Desgleichen können derartige Programmeingaben auch durch eine kombinierte Bedienung der Drehwahlschalter 3 und 17 sowie der Tasten 4 bis 9 erfolgen. Beispielsweise kann die Reihenfolge der Eingaben durch jeweilige Einstellungen bestimmter Drehpositionen des Drehwahlschalters 3 und/oder 17 bestimmt werden, während die einzugebenden Drehpositionen durch Betätigen einer bestimm- ten der Tasten 4 bis 9 oder durch Drücken des betreffenden Drehwahlschalters quittiert werden. Zur Kontrolle der Eingriffshandlungen kann beispielsweise das alphanumerische Display 16 dienen. Dabei müssen bestimmte für entsprechende Maßnahmen vorgesehene und zugeordnete Anzeigebilder entstehen, die die korrekte Eingriffshandlung bestätigen. Im Falle von zu verän- dernden Parameterwerten können solche Bilder die Anzeige von bestimmten Zahlenwerten sein.According to the invention, an initiated person (eg a customer service technician) can change certain operating program sequences or certain parameter values of program functions by entering a certain sequence of functions on the operating handles. For example, he can perform a certain sequence of key operations in order to influence the duration of a washing phase or to correct the temperature of the alkali for a certain program sequence downwards or upwards. Likewise, such program entries can also be made by a combined operation of the rotary selector switches 3 and 17 and the keys 4 to 9. For example, the order of the inputs can be determined by respective settings of specific rotary positions of the rotary selector switch 3 and / or 17, while the rotary positions to be entered can be determined by actuating a specific ten of the buttons 4 to 9 or by pressing the relevant rotary selector switch. The alphanumeric display 16 can be used, for example, to control the intervention. Certain display images provided and assigned for corresponding measures must be created, which confirm the correct intervention. In the case of parameter values to be changed, such images can be the display of certain numerical values.
Programmelemente, die bei Waschmaschinen und Geschirrspülmaschinen veränderbar sind, können beispielsweise folgende Funktionen sein: Wasserzulauf, Laugenheizung, Trommelbewegung, Laugenumwälzung, Abpumpen der Lauge. Bei Wäschetrocknern können solche Programmelemente die Trommelbewegung, Rechtslauf, Linkslauf, Prozeßluftförderung, Kühlluftför- derung und Kondensatabführung sein. Als veränderbare Parameter von Programmfunktionen sind bei Waschmaschinen und Geschirrspülmaschinen folgende Einstellungen möglich: Laugenniveau, Laugentemperatur, Zeitdauer, Zeittakte und Trommeldrehzahl. Bei Wäschetrocknern können folgende Parameter eingestellt werden: Prozeßlufttemperatur, Restfeuchte, Zeitdauer, Zeittakte. Die vorstehenden Angaben sind nur als Beispiele für solche Programmelemente oder Parameter zu verstehen. Program elements that can be changed in washing machines and dishwashers can be, for example, the following functions: water supply, lye heating, drum movement, lye circulation, pumping out the lye. In the case of tumble dryers, such program elements can be drum movement, clockwise rotation, counterclockwise rotation, process air supply, cooling air supply and condensate discharge. The following settings are possible as changeable parameters of program functions for washing machines and dishwashers: alkali level, alkali temperature, time duration, time cycles and drum speed. The following parameters can be set for tumble dryers: process air temperature, residual moisture, time duration, time cycles. The above information is only to be understood as examples of such program elements or parameters.
