Gemäß einer bevorzugten Ausgestaltung der Erfindung weist die Anzeigeeinrichtung mehrere LEDs auf, insbesondere LEDs unterschiedlicher Farbe. Damit kann in einfach erkennbarer und eindringlicher Weise dem Benutzer hinsichtlich mehrerer zu überwachender Zustände im oder am Hause die gewünschte Information gegeben werden. Ist zum Beispiel der zu überwachende Zustand die Temperatur einer entfernt vom genannten Kühlschrank angeordneten Tiefkühltruhe (zum Beispiel im Keller), dann kann für diesen Zustand eine "Ampel" mit zum Beispiel drei Farben grün, gelb und rot vorgesehen werden, wobei der weiter unten beschriebene Rechner dann, wenn die Temperatur in der Tiefkühltruhe dem vorgesehenen Wert entspricht, mit der LED das grüne Licht aktiviert, während dann, wenn die Temperatur nahe einem unerwünschten Grenzbereich liegt, mit der LED die Farbe gelb angezeigt wird, und dann, wenn die Temperatur in der Tiefkühltruhe oberhalb einem vorgegebenen Grenzwert liegt, mit der LED die Farbe rot angezeigt wird.According to a preferred embodiment of the invention, the display device has a plurality of LEDs, in particular LEDs of different colors. Thus, the user can be given the desired information in an easily recognizable and urgent manner with respect to several states to be monitored in or at home. If, for example, the state to be monitored is the temperature of a freezer (for example in the cellar) remote from the said refrigerator, then a "traffic light" with, for example, three colors green, yellow and red can be provided for this state, the one described below Calculator then, when the temperature in the freezer corresponds to the intended value, with the LED activates the green light, while when the temperature is close to an undesirable limit, with the LED the color is yellow, and then when the temperature in the freezer is above a predetermined limit, with the LED the color is displayed in red.

Figur 1 zeigt einen Kühlschrank 10, der zum Beispiel zwei Türen 12, 14 aufweist, die Zugang zu unterschiedlichen Kühlräumen ermöglichen. In einer Kopfleiste 16 über der oberen Tür 14 ist eine Anzeigeeinrichtung 18 mit einzelnen LEDs (LichtEmittierende-Dioden) angeordnet. Dabei können die Buchstaben a, b, c und d jeweils unterschiedliche LED mit verschiedenen Farben kennzeichnen, zum Beispiel grün, gelb, orange und rot. Diese Farben können in sinnfälliger Weise unterschiedlichen Zuständen eines zu überwachenden Parameters, zum Beispiel der Temperatur in einer Tiefkühltruhe, zugeordnet werden. Es würden, in einem einfachen Fall, auch drei LEDs ausreichen, um einem Besucher mit hinreichender Genauigkeit die jeweils aktuellen Zustände des zu überwachenden Parameters mitzuteilen.Figure 1 shows a
In Abwandlung des vorstehend beschriebenen Ausführungsbeispieles kann Figur 1 auch so zugeordnet werden, dass die Leuchtfelder 18a, 18b, 18c und 18d jeweils unterschiedlichen Zuständen, die im Haus überwacht werden, zugeordnet sind, also zum Beispiel das Leuchtfeld a der Temperatur in der Tiefkühltruhe, das Leuchtfeld b einer Feuchtigkeit an einem Ort im Keller des Hauses (Wasserschaden), das Leuchtfeld c dem Zustand einer Heizung (zum Beispiel einem mit zeitgemäßen Heizungsanlagen elektronisch ermittelten Betriebszustand), und das Leuchtfeld d einem vierten Parameter, wie zum Beispiel dem Öffnungszustand eines Garagentores (offen oder zu). Bei diesem Ausführungsbeispiel der Erfindung kann dann jedes der vier genannten Leuchtfelder a, b, c und d in unterschiedlichen Farben (zum Beispiel grün, gelb und rot) zum Leuchten gebracht werden. Hierfür stehen nach dem Stand der Technik LEDs zu Verfügung, die von einer Elektronik unterschiedlich elektrisch ansteuerbar sind und dabei zum Beispiel aus drei Farbkomponenten unterschiedliche Endfarben zusammenmischen, also zum Beispiel die gewünschten Endfarben grün, gelb oder rot.In a modification of the embodiment described above, Figure 1 can also be assigned so that the light panels 18a, 18b, 18c and 18d respectively different states that are monitored in the house, are assigned, so for example, the light field a of the temperature in the freezer, the Light field b of a moisture at a location in the basement of the house (water damage), the illuminated field c the state of a heater (for example, an electronically detected with modern heating systems operating state), and the light field d a fourth parameter, such as the opening state of a garage door ( open or closed). In this embodiment of the invention, each of the four luminous fields a, b, c and d can then be illuminated in different colors (for example green, yellow and red). For this purpose, according to the state of the art, LEDs are available which can be controlled differently by an electronic system and, for example, mix different final colors together from three color components, that is, for example, the desired end colors green, yellow or red.

So kann zum Beispiel der Sensor 28 eine Überwachung eines Garagentores vornehmen, also ermitteln, ob das Tor zuverlässig geschlossen ist oder nicht. Je nach dem ermittelten Zustand des Tores gibt der Sensor 28 dann über eine Leitung 36 ein entsprechendes Signal an einen Rechner 26 (der auch als festverdrahtete Elektronik ausgebildet sein kann), der dieses Signal verarbeitet und entsprechend eine Anzeigeeinrichtung, zum Beispiel 18, ansteuert. Dabei ist die Anzeigeinrichtung 18 mit LEDs so versehen, dass der Rechner 26 eine Schaltung der LEDs dahingehend vornimmt, dass bei geschlossenem Garagentor das dem Anzeigegerät 18 zugeordnete Leuchtfeld (zum Beispiel das Feld a in Figur 1) grün aufleuchtet, während dann, wenn das Garagentor nicht geschlossen ist, das Leuchtfeld a rot aufleuchtet, bei entsprechend anderer Beaufschlagung der diesem Leuchtfeld zugeordneten LEDs.According to FIG. 2,
Der Sensor 30 kann zum Beispiel ein Meldegerät sein, welches Wasser meldet an einer unerwünschten Stelle, zum Beispiel in der Küche hinter Schränken oder im Keller, zum Beispiel nahe einer Waschmaschine oder dergleichen. Der Sensor 30 meldet dann ein entsprechendes Signal über die Leitung 38 an den Rechner 26, der die Auswertung vornimmt, um dann eine andere Anzeigeeinrichtung 20 in Form eines anderen Leuchtfeldes, also zum Beispiel des Leuchtfeldes b in Figur 1, analog dem oben beschriebenen Garagentor anzusteuern.The

Entsprechendes gilt auch für den oben beschriebenen Zustand des Garagentores, der zum Beispiel elektrisch durch einen einfachen Schalter, der im Schließzustand geschlossen wird, ermittelbar ist.Measuring instruments with which the moisture itself can be measured are available to the person skilled in the art from other sources. The same applies to the above-described state of the garage door, which can be determined, for example, electrically by a simple switch, which is closed in the closed state.
Beim Sensor 32 kann es sich zum Beispiel um ein Gerät handeln, mit dem eine Heizung überwacht wird, also zum Beispiel die Feststellung, ob die Heizung betriebsbereit ist, eine Störung vorliegt, oder ausgeschaltet ist. Solche Heizungsüberwachungen sind als solche dem Fachmann bekannt. Sie können ein gewünschtes Signal über den Heizungszustand liefern, welches dann beim Ausführungsbeispiel gemäß Figur 2 drahtlos über die Funkstrecke 40 dem Rechner 26 mitgeteilt wird, der hierfür einen entsprechenden Empfänger aufweist. Die Auswertung erfolgt analog der oben beschriebenen, also derart, dass die dem Heizungszustand zugeordnete Anzeigeeinrichtung 22 zum Beispiel dem Feld c in Figur 1 entspricht, wobei ein rotes Signal anzeigt, dass bei der Heizungsanlage ein Störzustand vorliegt.The sensor 32 may be, for example, a device with which a heater is monitored, for example, the determination of whether the heater is ready for operation, there is a fault, or is turned off. Such heating monitors are known as such to the person skilled in the art. They can provide a desired signal on the heating state, which is then communicated wirelessly in the embodiment of Figure 2 via the radio link 40 to the
Analog kann es sich bei dem weiteren Sensor 34 auch zum Beispiel um eine Überwachungseinrichtung handeln, die die Temperatur in einer Gartenwasserleitung (außerhalb des Hauses) misst, um eine eventuelle Gefriergefahr anzuzeigen. Bei diesem Sensor 34 erfolgt die Übertragung des Signals zum Rechner 26 drahtlos über die Infrarotstrecke 42, für die dann der Rechner 26 mit einem entsprechenden Empfänger ausgerüstet ist.Analogously, the further sensor 34 may also be, for example, a monitoring device which measures the temperature in a garden water line (outside the house) in order to indicate a possible risk of freezing. In this Sensor 34, the transmission of the signal to the
