Description

Anzeige an einem HaushaltgerätDisplay on a household appliance
Die vorliegende Erfindung betrifft eine Anzeige an einem Haushaltgerät, insbesondere an einem Wäschepflegegerät.The present invention relates to a display on a household appliance, in particular on a laundry care device.
Aus dem Stand der Technik sind Wäschepflegegeräte wie beispielsweise Waschmaschinen, Kombinationsgeräte zum Waschen und Schleudern sowie Wäschetrockner bekannt, welche als Arbeitselement eine die Wäsche aufnehmende, rotierende Trommel aufwei- sen. Zum Einstellen von Wasch- oder Schleuderprogrammen sowie der Waschtemperaturen dient in der Regel ein in der Frontblende aufgenommener Drehschalter, dessen Drehknebel mit einer Markierungslinie versehen ist. Der Drehknebel ist von einem Leuchtring umgeben, auf oder neben welchem Waschtemperaturen sowie Wasch- oder Schleuderprogramme angetragen sind. Dabei ist jeweils die Waschtemperatur oder das Wasch- oder Schleuderprogramm eingestellt, auf welches die Markierungslinie des Drehknebels weist. Dem bekannten Leuchtring sind über seinen gesamten Umfang gleichmäßig verteilte und mit Umfangsabstand zueinander angeordnete Leuchtdioden zugeordnet. Gemäß einer bekannten Leuchtringansteuerung werden sämtliche Leuchtdioden des Leuchtrings gleichzeitig und gleichmäßig ausgeleuchtet, um die dem Leuchtring zugeordnete Skala zu beleuchten.From the prior art, laundry care devices such as washing machines, combination devices for washing and spinning and tumble dryers are known, which have a rotating drum that receives the laundry as a working element. A rotary switch in the front panel, whose rotary knob is provided with a marking line, is usually used to set washing or spinning programs and the washing temperatures. The rotary knob is surrounded by a light ring on or next to which washing temperatures as well as washing or spinning programs are indicated. The washing temperature or the washing or spinning program is set to which the marking line of the rotary knob points. The known light ring is assigned uniformly distributed light-emitting diodes over its entire circumference and spaced apart from one another. According to a known light ring control, all the light-emitting diodes of the light ring are illuminated simultaneously and uniformly in order to illuminate the scale assigned to the light ring.
Aufgabe der vorliegenden Erfindung ist es, eine Anzeige nach dem Oberbegriff des Patentanspruchs 1 dahingehend weiter zu entwickeln, daß die momentan vorliegende Rotationsgeschwindigkeit eines Arbeitselements des Haushaltgeräts und/oder der Status des gerade ablaufenden Geräteprogrammes veranschaulicht werden kann.The object of the present invention is to further develop a display according to the preamble of claim 1 to the extent that the current rotational speed of a working element of the household appliance and / or the status of the appliance program currently running can be illustrated.
Erfindungsgemäß wird dies bei einer Anzeige nach dem Oberbegriff des Patentanspruchs 1 dadurch erreicht, daß sie eine Geschwindigkeitsanzeige für die Rotationsgeschwindigkeit eines rotierenden Arbeitselements des Haushaltgeräts aufweist, beinhal- tend ein in sich geschlossenes Leuchtelement-Band mit entlang seines Umfangs ange- ordneten Leuchtelementen, welche derart angesteuert sind, daß sie mit einer Umdrehungsgeschwindigkeit rotierend aufblinken, welche proportional zu einer momentanen Rotationsgeschwindigkeit des Arbeitselements ist und /oder daß sie eine Programmablaufanzeige aufweist, beinhaltend ein Leuchtelement-Band mit Leuchtelementen, welche derart angesteuert sind, daß ausgehend von einem ersten Leuchtelement des Leuchtelement-Bandes mit steigender Programmdauer eine größere Anzahl von Leuchtelementen beleuchtet wird und bei Programmende alle Leuchtelemente des Leuchtelement- Bandes beleuchtet sind oder daß ausgehend von einem ersten Leuchtelement des Leuchtelement-Bandes jeweils nur das Leuchtelement beleuchtet wird, dessen Stellung innerhalb des Leuchtelement-Bandes der momentan vergangenen Programmdauer entspricht.According to the invention, this is achieved in a display according to the preamble of patent claim 1 in that it has a speed display for the rotational speed of a rotating working element of the household appliance, including a self-contained strip of luminous elements with a circumference attached along its circumference. arranged lighting elements which are controlled in such a way that they flash in a rotating manner at a rotational speed which is proportional to a current rotational speed of the working element and / or that it has a program sequence display, including a lighting element band with lighting elements which are controlled in such a way that starting from a first light element of the light element band with increasing program duration a larger number of light elements is illuminated and at the end of the program all light elements of the light element band are illuminated or that starting from a first light element of the light element band only the light element is illuminated, the position of which within the Luminous element band corresponds to the current duration of the program.
Durch die erfindungsgemäße Geschwindigkeitsanzeige ist es möglich, auf symbolisch einfache Weise einer Bedienperson die jeweils vorliegende Rotationsgeschwindigkeit und die Rotationsrichtung des Arbeitselements durch einen sich entlang des Leuchtelement-The speed display according to the invention makes it possible, in a symbolically simple manner, for an operator to determine the rotational speed and the direction of rotation of the working element in each case by means of a
Bandes bewegenden Lichtpunkt darzustellen, was auch einen Rückschluß über das gerade ablaufende Programm des Haushaltgeräts zulässt. Somit kann eine Bedienperson, selbst wenn sie sich im Abstand zu dem Haushaltgerät befindet und dessen Betrieb nur oberflächlich beobachtet, sich auf einen Blick über die momentane Drehzahl des Arbeits- elements und somit auch über den momentanen erreichten Programmschritt des Haushaltgeräts informieren. Die dargestellte Information ist dabei leicht verständlich, da ein sich schneller drehendes Arbeitselement ein schnelleres Rotationsblinken der Leuchtdioden des Leuchtrings hervorruft und umgekehrt. Darüber hinaus ermöglicht auch die erfindungsgemäße Programmablaufanzeige eine schnelle Information über den zeitlichen Fortschritt des gerade ablaufenden Programmes, weil sie als optisch leicht erfaßbareTo represent the band's moving point of light, which also allows a conclusion to be drawn about the current program of the household appliance. Thus, an operator, even if he is at a distance from the household appliance and only superficially observes its operation, can obtain information at a glance about the current speed of the working element and thus also about the current program step of the household appliance. The information shown is easy to understand, since a faster rotating working element causes the LEDs of the light ring to flash faster and vice versa. In addition, the program sequence display according to the invention also enables quick information about the temporal progress of the currently running program, because it is easy to grasp optically
Analoganzeige ähnlich einem Balkendiagramm präsentiert wird.Analog display is presented similar to a bar chart.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird das Leuchtelement-Band der Geschwindigkeitsanzeige durch einen kreisförmigen Leuchtring mit entlang seines Umfangs angeordneten Leuchtelementen gebildet, welche in Drehrichtung des Arbeitselements rotierend aufblinken.According to a preferred embodiment of the invention, the light element band of the speed indicator is formed by a circular light ring with light elements arranged along its circumference, which flash in a rotating manner in the direction of rotation of the working element.
Im Sinne einer Funktionsvereinigung sind gemäß einer Weiterbildung mit Hilfe eines einzigen Leuchtrings wahlweise die Geschwindigkeitsanzeige, die Programmablaufanzeige oder weitere Funktionen darstellbar. Hierzu kann das Leuchtelement-BandIn the sense of a function combination, according to a further development, the speed display, the program sequence display or other functions can be displayed with the aid of a single light ring. For this purpose, the light element tape

Nachfolgend sind anhand schematischer Darstellungen mehrere Ausführungsbeispiele der erfindungsgemäßen Anzeige beschrieben.Several exemplary embodiments of the display according to the invention are described below using schematic representations.

Ausführungsform der Erfindung.Embodiment of the invention.
In einer Frontblende 1 eines ansonsten nicht näher dargestellten Kombinationsgeräts zum Waschen und Schleudern von Wäsche ist ein Drehschalter 2 mit einem aus der Frontblende 1 ragenden Drehknebel 4 mit einer Markierung 6 drehbar gehalten. DerIn a front panel 1 of an otherwise not shown combination device for washing and spinning laundry, a rotary switch 2 is rotatably held with a rotary knob 4 protruding from the front panel 1 with a marking 6. The
Drehschalter 2 dient zum Einstellen von Wasch- und Schleuderprogrammen sowie von Waschtemperaturen, welche neben einem den Drehknebel 4 vollständig umgebenden transparenten Leuchtring 8 umfangsseitig angetragen sind. In bekannter Weise ist dabei jeweils die Waschtemperatur bzw. das Wasch- oder Schleuderprogramm eingestellt, auf welches die Markierung 6 des Drehknebels 4 weist. Der Leuchtring 8 bildet ein Leuchtelement-Band, wobei auf der von einem frontseitigen Betrachter weg weisenden Seite des Leuchtrings 8 entlang seines Umfangs mehrere Leuchtdioden 10 mit Umfangsab- stand zueinander angeordnet sind. Erfindungsgemäß fungiert der Leuchtring 8 als Geschwindigkeits- und Drehrichtungsanzeige für die Rotation einer Wäschetrommel des Kombinationsgeräts. Hierzu stehen die Leuchtdioden 10 des Leuchtrings 8 mit einer aus Maßstabsgründen nicht dargestellten Steuereinrichtung in Verbindung, welche von einem Drehzahlsensor die momentaneRotary switch 2 is used to set washing and spinning programs and washing temperatures, which are indicated on the circumference in addition to a transparent light ring 8 completely surrounding the rotary knob 4. In each case, the washing temperature or the washing or spinning program to which the mark 6 of the rotary knob 4 points is set in a known manner. The light ring 8 forms a light-emitting element band, a plurality of light-emitting diodes 10 having a circumferential spacing from one another being arranged along its circumference on the side of the light ring 8 pointing away from a front viewer. According to the invention, the light ring 8 functions as a speed and direction of rotation indicator for the rotation of a laundry drum of the combination device. For this purpose, the light-emitting diodes 10 of the light ring 8 are connected to a control device, not shown for reasons of scale, which controls the instantaneous value of a speed sensor
Drehzahl der Wäschetrommel als Sensorsignal erhält. Die Leuchtdioden 10 sind dabei von der Steuereinrichtung derart selektiv angesteuert, daß sie mit einer Umdrehungsgeschwindigkeit rotierend aufblinken, welche proportional zu einer Rotationsgeschwindigkeit der Wäschetrommel des Kombinationsgeräts ist. Beispielsweise ist die Umdrehungsge- schwindigkeit des rotierenden Aufblinkens der Leuchtdioden 10 im Betriebszustand „Waschen" geringer als beim Betriebszustand „Schleudern". Das rotierende Aufblinken der Leuchtdioden 10 erfolgt, wie durch die Pfeile in der Figur angedeutet ist, vorzugsweise im gerade vorliegenden Drehsinn der Wäschetrommel.Speed of the laundry drum receives as a sensor signal. The light emitting diodes 10 are so selectively actuated by the control device that they flash in a rotating manner which is proportional to a rotational speed of the laundry drum of the combination device. For example, the rotational speed of the flashing of the light-emitting diodes 10 is lower in the “washing” operating state than in the “spinning” operating state. The rotating flashing of the light-emitting diodes 10 takes place, as indicated by the arrows in the figure, preferably in the currently existing direction of rotation of the laundry drum.
Rotierendes Aufblinken bedeutet, daß von den einzelnen Leuchtdioden 10 jeweils eine kurzzeitig aufblinkt und zeitversetzt die im Uhrzeigersinn oder im Gegenuhrzeigersinn jeweils benachbarte Leuchtdiode 10 nachfolgt. Dem Betrachter erscheint dieser Vorgang dann so, als ob sich ein Lichtpunkt 12 mit einer bestimmten Rotationsgeschwindigkeit entlang des Umfangs des Leuchtrings 10 bewegt.Rotating flashing means that one of the individual light-emitting diodes 10 flashes briefly and the light-emitting diode 10, which is adjacent in the clockwise or counterclockwise direction, follows with a time delay. This process then appears to the viewer as if a point of light 12 is moving at a certain rotational speed along the circumference of the light ring 10.
Gemäß einer weiteren, in Fig.2 dargestellten Ausführungsform wird die Geschwindigkeitsanzeige für die Rotationsgeschwindigkeit und Rotationsrichtung der Wäschetrommel ebenfalls durch einen Leuchtring 14 mit entlang seines Umfangs mit Umfangsabstand zueinander angeordneten Leuchtdioden 16 gebildet. Im Unterschied zum vorangehend beschriebenen Ausführungsbeispiel umgibt der Leuchtring 14 ein Bullauge 18 des Wäschepflegegeräts. Alternativ kann der Leuchtring 14 auch entlang des Umfangsrandes des Bullauges 18 selbst verlaufen. Die Ansteuerung der Leuchtdioden 16 erfolgt analog dem vorangehenden Ausführungsbeispiel in der Weise, daß diese mit einer Umdrehungsgeschwindigkeit rotierend aufblinken, welche proportional zu einer Rotationsge- schwindigkeit der Wäschetrommel ist. Für den Betrachter erscheint dies dann als ein sich entlang des Leuchtrings 14 bewegender Lichtpunkt, dessen Drehrichtung vorzugsweise mit der der Wäschetrommel identisch ist. Darüber hinaus erfüllt der Leuchtring 14 vorzugsweise eine weitere Funktion, indem er zugleich als Programmablaufanzeige des gerade ablaufenden Programmes des Kombinationsgeräts dient. Hierzu werden in Reihe nacheinander die Leuchtdioden des Leuchtrings 14 aktiviert, deren Anzahl dem momentanen Fortschritt des Programmablaufs ent- spricht. Dies bedeutet, daß beispielsweise ausgehend von der im Leuchtring 14 oberstenAccording to a further embodiment shown in FIG. 2, the speed display for the rotation speed and direction of rotation of the laundry drum is likewise formed by a light ring 14 with light-emitting diodes 16 arranged along its circumference at a circumferential distance from one another. In contrast to the exemplary embodiment described above, the light ring 14 surrounds a porthole 18 of the laundry care device. Alternatively, the light ring 14 can also run along the peripheral edge of the porthole 18 itself. The control of the light-emitting diodes 16 takes place analogously to the preceding exemplary embodiment in such a way that they flash at a rotational speed which is proportional to a rotational speed of the laundry drum. To the viewer, this then appears as a point of light moving along the light ring 14, the direction of rotation of which is preferably identical to that of the laundry drum. In addition, the illuminated ring 14 preferably fulfills a further function in that it also serves as a program sequence display of the program of the combination device that is currently running. For this purpose, the LEDs of the light ring 14 are activated one after the other, the number of which corresponds to the current progress of the program. This means that, for example, starting from the uppermost in the illuminated ring 14
Leuchtdiode 20 im Uhrzeigersinn proportional zum zeitlichen Programmlauf eine steigende Anzahl von Leuchtdioden 16 aktiviert werden, so daß, wenn das Programm beispielsweise zu 50% abgelaufen ist, die Leuchtdioden eines Kreisbogens 22 von 180 Grad aufleuchten, wie in Fig.3 veranschaulicht ist. Bei Erreichen des Programmendes sind dann schließlich die Leuchtdioden 16 des genannten Leuchtrings 14 aktiviert. Um das Erreichen des Programmmendes besonders zu kennzeichnen, können darüber hinaus sämtliche Leuchtdioden 16 des Leuchtrings 14 aufblinken.Light-emitting diode 20 clockwise in proportion to the time program run an increasing number of light-emitting diodes 16 are activated, so that when the program has run for example 50%, the light-emitting diodes of an arc 22 of 180 degrees light up, as illustrated in FIG. 3. When the program ends, the light emitting diodes 16 of the light ring 14 mentioned are finally activated. In order to particularly mark the end of the program, all the light-emitting diodes 16 of the light ring 14 can also flash.
Die beiden Anzeigefunktionen des Leuchtringes 14, die Geschwindigkeitsanzeige einer- seits und die Programmablaufanzeige andererseits, können sich automatisch abwechseln oder wahlweise programmiert werden. Insbesondere können für die beiden Funktionen Leuchtelemente verschiedener Farbe vorhanden sein und die Geschwindigkeitsanzeige in einer von der Farbe der Programmablaufanzeige unterschiedlichen Farbe erfolgen. Dann sind auf dem Leuchtring 14 beispielsweise Leuchtelemente 16 verschiedener Farbe ab- wechselnd hintereinander angeordnet. Eine Verwendung von Leuchtdioden 16 alsThe two display functions of the light ring 14, the speed display on the one hand and the program sequence display on the other hand, can alternate automatically or can be programmed optionally. In particular, lighting elements of different colors can be present for the two functions and the speed display can take place in a color different from the color of the program sequence display. Then, for example, lighting elements 16 of different colors are arranged alternately one behind the other on the lighting ring 14. Use of LEDs 16 as
Leuchtelemente ist nicht zwingend notwendig, ebenso kann jegliche andere Art von selektiv ansteuerbaren Leuchtelementen verwendet werden, beispielsweise auch mit Lichtquellen verbundene Lichtleiter, deren freie Enden im Leuchtring 14 aufgenommen sind.Luminous elements are not absolutely necessary, and any other type of selectively controllable luminous elements can also be used, for example also light guides connected to light sources, the free ends of which are accommodated in the light ring 14.
Die beschriebenen Anzeigen mittels Leuchtringen 8, 14 sind nicht auf eine Verwendung inThe displays described by means of light rings 8, 14 are not for use in
Kombinationsgeräten zum Waschen und Schleudern von Wäsche beschränkt, vielmehr können sie für jegliche Art von mit einem rotierenden Arbeitselement ausgestatteten Haushaltgeräten eingesetzt werden, beispielsweise auch für Küchenmixer.Combination devices for washing and spinning laundry limited, rather they can be used for any type of household appliances equipped with a rotating work element, for example also for kitchen mixers.
In Fig. 4 ist eine weitere Ausführungsform einer Programmablaufanzeige mit einem4 shows a further embodiment of a program flow display with a
Leuchtelement-Band 24 dargestellt, welches vorzugsweise in linearer und horizontaler Reihe angeordnete Leuchtelemente 26 aufweist, die derart angesteuert sind, daß ähnlich einem Balkendiagramm ausgehend von einem ersten Leuchtelement 28 des Leuchtelement-Bandes 24 mit steigender Programmdauer eine größere Anzahl von Leuchtelemen- ten beleuchtet wird und bei Programmende alle Leuchtelemente 26 beleuchtet sind. Die aktivierten Leuchtelemente 26 bilden somit einen Lichtbalken 30, dessen Länge von der bisherigen Dauer des Programmlaufs abhängt. Zusätzlich kann die Programmablaufanzeige eine digitale Anzeige 32 zum Anzeigen der Uhrzeit des Endes des jeweiligen Pro- grammes enthalten.Illuminated element band 24 is shown, which preferably has linear elements 26 arranged in a linear and horizontal row, which are controlled in such a way that, like a bar chart, a larger number of illuminating elements is illuminated with increasing program duration, starting from a first illuminating element 28 of the illuminating element band 24 and at the end of the program all lighting elements 26 are illuminated. The activated lighting elements 26 thus form a light bar 30, the length of which depends on the previous duration of the program run. In addition, the program sequence display can contain a digital display 32 for displaying the time of the end of the respective program.
In der Ausführungsform von Fig.5 ist parallel zum Leuchtelement-Band 34 der Programmablaufanzeige eine Zeitskala 36 von 0 bis 80 Minuten in Zeitschritten von 20 Minuten angetragen, um dem aus Leuchtelementen 37 gebildeten Lichtbalken 38 eine bestimmte Programmlaufzeit zuordnen zu können.In the embodiment of FIG. 5, a time scale 36 from 0 to 80 minutes in time increments of 20 minutes is plotted parallel to the luminous element band 34 of the program sequence display in order to be able to assign a specific program runtime to the light bar 38 formed from luminous elements 37.
Gemäß der Ausführungsform von Fig.6 wird ausgehend vom ersten Leuchtelement 40 der Leuchtelemente 41 des Leuchtelement-Bandes 42 jeweils nur das Leuchtelement 44 aktiviert, dessen Stellung in der Reihe von Leuchtelementen 41 der momentan vergangenen Programmdauer entspricht. Demzufolge ergibt sich ein von links nach rechts wan- dernder Lichtpunkt 44, wobei der Programmablauf umso weiter fortgeschritten ist, je weiter rechts sich der Lichtpunkt 44 befindet. Anfang und Ende des Leuchtelement- Bandes 42 können zusätzlich durch ständig aktivierte Leuchtelemente 40, 46 markiert sein.According to the embodiment of FIG. 6, starting from the first lighting element 40 of the lighting elements 41 of the lighting element band 42, only the lighting element 44 is activated in each case, the position of which in the row of lighting elements 41 corresponds to the currently past program duration. This results in a light spot 44 moving from left to right, the program sequence having progressed the further the light spot 44 is located to the right. The beginning and end of the lighting element band 42 can additionally be marked by permanently activated lighting elements 40, 46.
Die Form der Programmablaufanzeige und/oder der Geschwindigkeitsanzeige ist nicht auf kreisrunde oder lineare Leuchtelement-Bänder 8, 14, 24, 34, 42 beschränkt, vielmehr können hierzu beliebige Formen wie beispielsweise Rechtecke oder Ellipsen verwendet werden. Dabei kann ein Leuchtelement-Band 8, 14, 24, 34, 42 Leuchtelemente verschiedener Farben aufweisen, wobei jede Farbe eine eigene Funktion symbolisiert. Beispiels- weise kann durch blaue Leuchtelemente der relative Programmablauf, durch weiße oder grüne Leuchtelemente die Rotationsgeschwindigkeit des Arbeitselements und durch rot aufblinkende Leuchtelemente eine Störung dargestellt werden. The form of the program sequence display and / or the speed display is not limited to circular or linear light element strips 8, 14, 24, 34, 42; rather, any shapes such as rectangles or ellipses can be used for this purpose. A light element band 8, 14, 24, 34, 42 can have light elements of different colors, each color symbolizing its own function. For example, the relative program sequence can be represented by blue light elements, the speed of rotation of the work element by white or green light elements, and a fault can be represented by light elements flashing red.
