Description
Kältegerät mit Innenraumbeleuchtung Refrigerator with interior lighting
Die vorliegende Erfindung betrifft ein Kältegerät mit Innenraumbeleuchtung.The present invention relates to a refrigerator with interior lighting.
Kältegeräte wie etwa Kühlschränke oder Gefriergeräte sind herkömmlicherweise mit einer Innenraumbeleuchtung versehen, die durch einen an der Tür des Geräts angeordneten Schalter automatisch ein- und ausgeschaltet wird.Refrigerating devices such as refrigerators or freezers are conventionally provided with interior lighting which is automatically switched on and off by a switch arranged on the door of the device.
Die gegenwärtig für die Innenraumbeleuchtung von Kältegeräten verwendeten Leuchtmittel setzen nur einen geringen Bruchteil ihrer elektrischen Leistungsaufnahme tatsächlich in Lichtleistung um; der bei weitem überwiegende Teil der Leistungsaufnahme wird in Wärme umgesetzt, die den Innenraum unerwünschterweise aufheizt und abgeführt werden muss. Dieser Wärmeeintrag ließe sich natürlich durch den Verzicht auf eine Innenraumbeleuchtung vermeiden; andererseits wird die Beleuchtung als notwendig empfunden, um einen gesuchten Gegenstand in dem Innenraum schnell auffinden zu können.The illuminants currently used for the interior lighting of refrigeration appliances actually only convert a small fraction of their electrical power consumption into light output; the vast majority of the power consumption is converted into heat, which undesirably heats up and dissipates the interior. This heat input could of course be avoided by dispensing with interior lighting; on the other hand, the lighting is felt to be necessary in order to be able to find a desired object quickly in the interior.
Aufgabe der vorliegenden Erfindung ist, ein Kältegerät anzugeben, bei dem die Erwärmung des Innenraumes durch dessen Beleuchtung reduzierbar ist, ohne dass dies mit einer Verminderung des Komforts für den Benutzer erkauft werden muss. Im Gegenteil kann bei geschickter Anwendung der Komfort für den Benutzer sogar noch gesteigert werden.The object of the present invention is to provide a refrigeration device in which the heating of the interior can be reduced by illuminating it, without this having to be bought with a reduction in comfort for the user. On the contrary, comfort for the user can even be increased with skillful use.
Die Aufgabe wird gelöst durch ein Kältegerät mit Innenraumbeleuchtung, das mit einerThe task is solved by a refrigerator with interior lighting, which with a
Steuerschaltung zum Steuern der Leistung der Innenraumbeleuchtung in Abhängigkeit von einem von einem lichtempfindlichen Element erfassten Helligkeitswert ausgerüstet ist.Control circuit for controlling the performance of the interior lighting depending on a brightness value detected by a light-sensitive element.
Eine solche Steuerschaltung erlaubt die Steuerung, insbesondere die Reduzierung, der Leistung der Innenraumbeleuchtung, wenn die Umgebungshelligkeit ausreicht, um auch den Innenraum des Kältegeräts bei geöffneter Tür hinreichend auszuleuchten.Such a control circuit allows the control, in particular the reduction, of the output of the interior lighting if the ambient brightness is sufficient to also adequately illuminate the interior of the refrigerator when the door is open.
Einer ersten Ausgestaltung der Erfindung zufolge ist das lichtempfindliche Element an einer Außenseite des Kältegeräts angeordnet, um direkt die Intensität des Lichts in der Umgebung des Kältegeräts zu erfassen. Vorzugsweise befindet sich das lichtempfindliche Element an einer Bedienblende des Kältegeräts, die zusammen mit der Tür die Sichtseite des Kältegeräts bildet und somit einer Umgebungslichtstärke ausgesetzt ist, die bei geöffneter Tür auch in den Innenraum des Kältegerätes fällt. Die Anbringung an der Bedienblende ist auch deshalb bevorzugt, weil dies die Verdrahtung des lichtempfindlichen Elements mit der zugeordneten Steuerschaltung mit geringem Aufwand, zusammen mit der Verdrahtung anderer Bedienelemente erlaubt.According to a first embodiment of the invention, the light-sensitive element is arranged on an outside of the refrigeration device in order to directly determine the intensity of the light in the Detect the environment of the refrigerator. The light-sensitive element is preferably located on an operating panel of the refrigeration device, which together with the door forms the visible side of the refrigeration device and is thus exposed to an ambient light intensity that also falls into the interior of the refrigeration device when the door is open. The attachment to the control panel is also preferred because this allows the wiring of the light-sensitive element with the associated control circuit with little effort, together with the wiring of other control elements.
Einer zweiten Ausgestaltung der Erfindung zufolge ist das lichtempfindliche Element im Innenraum des Kältegeräts angeordnet, so dass es der kombinierten Intensität der Innenraumbeleuchtung und des Umgebungslichts (bei geöffneter Tür) ausgesetzt ist. Diese Ausgestaltung erlaubt insbesondere die Regelung der Leistung der Innenraumbeleuchtung in Abhängigkeit vom Öffnungsgrad der Tür oder von der Abschattung des Innenraums durch einen davor stehenden Benutzer.According to a second embodiment of the invention, the light-sensitive element is arranged in the interior of the refrigerator, so that it is exposed to the combined intensity of the interior lighting and the ambient light (with the door open). This configuration allows in particular the regulation of the performance of the interior lighting depending on the degree of opening of the door or the shading of the interior by a user standing in front of it.
Bei dieser Ausgestaltung können das lichtempfindliche Element und die Steuerschaltung mit der Innenraumbeleuchtung zu einer Baueinheit verbunden sein, die als ein vorgefertigtes Element im Innenraum montierbar ist. Der Aufwand für die Montage eines solchen Elements ist nicht höher als der für die Montage einer herkömmlichen Innenraumbeleuchtung.In this embodiment, the light-sensitive element and the control circuit can be connected to the interior lighting to form a structural unit which can be installed as a prefabricated element in the interior. The effort for the assembly of such an element is not higher than that for the assembly of a conventional interior lighting.
Vorzugsweise ist die Steuerschaltung mit einem Stellglied zum Einstellen der Abhängigkeit zwischen erfasstem Helligkeitswert und Leistung der Innenraumbeleuchtung ausgestattet. Durch Einstellen eines solchen Stellgliedes kann ein Benutzer das Verhalten der Steuerschaltung an seine persönlichen Bedürfnisse anpassen. So kann z.B. die Steuerung so vorgenommen werden, dass die von der Steuerschaltung eingestellte Leistung der Innenraumbeleuchtung die von außen einfallende Lichtstärke ergänzt, so dass unabhängig von der Helligkeit der Umgebung stets eine im wesentlichen gleich bleibende Helligkeit im Innenraum erreicht wird, d.h. die von der Steuerschaltung eingestellte Leistung ändert sich gegenläufig zu einer Änderung der Umgebungshelligkeit; denkbar ist aber auch eine mit der Umgebungshelligkeit gleichläufige Regelung der Leistung der Innenraumbeleuchtung mit dem Ziel, eine in gewissem Umfang zur Umgebungshelligkeit proportionale Helligkeit im Innenraum zu erreichen. Wenn nämlich der Raum, in dem das Kältegerät aufgestellt ist, beispielsweise durch direkt hineinscheinendes Sonnenlicht extrem hell beleuchtet ist, und die Augen eines Benutzers an diese Beleuchtungsstärke angepasst sind, so benötigt er, um Gegenstände in dem Kältegerät bequem finden zu können, eine höhere Beleuchtungsstärke in diesem, als wenn er in einer dämmerigen Umgebung in das Kältegerät hineinschaut.The control circuit is preferably equipped with an actuator for setting the dependence between the detected brightness value and the power of the interior lighting. By setting such an actuator, a user can adapt the behavior of the control circuit to his personal needs. For example, the control can be carried out in such a way that the power of the interior lighting set by the control circuit supplements the luminous intensity incident from the outside, so that, regardless of the brightness of the surroundings, an essentially constant brightness is always achieved in the interior, ie that of the control circuit set power changes in the opposite direction to a change in the ambient brightness; However, it is also conceivable to regulate the output of the interior lighting in a manner consistent with the ambient brightness with the aim of achieving a brightness in the interior which is proportional to the ambient brightness to a certain extent. If the room in which the refrigerator is installed, for example, directly Sunlight shining in is extremely brightly lit, and the eyes of a user are adapted to this illuminance, so that in order to be able to find objects comfortably in the refrigeration device, the illuminance in the refrigeration device is higher than when looking into the refrigeration device in a dim environment.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen mit Bezug auf die beigefügten Figuren. Es zeigen:Further features and advantages of the invention result from the following description of exemplary embodiments with reference to the attached figures. Show it:
Fig. 1 einen schematischen Schnitt durch ein erfindungsgemäßes Kältegerät; und1 shows a schematic section through a refrigerator according to the invention; and
Fig. 2 eine Ansicht eines Gehäuses für eine Innenraumbeleuchtung gemäß einer zweiten Ausgestaltung der Erfindung.Fig. 2 is a view of a housing for interior lighting according to a second embodiment of the invention.
Fig. 1 zeigt einen schematischen Schnitt durch einen Kühlschrank gemäß einer ersten Ausgestaltung der Erfindung. Oberhalb der Tür 1 des Kühlschranks befindet sich an dessen Vorderseite eine Bedienblende 2, an der diverse, in der Fig. nicht dargestellte Einstell- und Anzeigeelemente, z.B. für die Temperatur des Innenraums, angeordnet sind. Hinter der Bedienblende 2 ist eine Steuerelektronik 3 untergebracht, mit der die diversen Bedien- und Anzeigeelemente verbunden sind, und die z.B. in herkömmlicher Weise den Betrieb eines (nicht dargestellten) Kühlmittelkreislaufs regelt.Fig. 1 shows a schematic section through a refrigerator according to a first embodiment of the invention. Above the door 1 of the refrigerator there is a control panel 2 on its front, on which various setting and display elements, not shown in the figure, e.g. for the temperature of the interior are arranged. Behind the control panel 2 there is control electronics 3 with which the various operating and display elements are connected and which e.g. regulates the operation of a coolant circuit (not shown) in a conventional manner.
Hinter einem lichtdurchlässigen Fenster der Bedienblende 2 ist als ein lichtempfindliches Element eine Photodiode 4 montiert, die einen für die Helligkeit in der Umgebung des Kühlschranks repräsentativen Photostrom an die Steuerelektronik 3 liefert.Behind a translucent window of the control panel 2, a photodiode 4 is mounted as a light-sensitive element and supplies a photocurrent representative of the brightness in the vicinity of the refrigerator to the control electronics 3.
Die Steuerelektronik 3 ist ferner mit einem Schalter 5 zum Erfassen der Öffnung bzw. Schließung der Tür 1 verbunden. Wenn der Schalter 5 einen geöffneten Zustand der Tür 1 anzeigt, so versorgt die Steuerelektronik 3 die Innenraumbeleuchtung 6 mit einem Strom, dessen Leistung sie in Abhängigkeit vom Photostrom der Photodiode 4 regelt. Beispiele für ein mögliches Regelverhalten der Steuerelektronik 3 sind als Kennlinien der Versorgungsleistung P für die Innenraumbeleuchtung in Abhängigkeit von der Intensität der Umgebungsbeleuchtung bzw. des Photostroms I dargestellt. Bei geringer Umgebungshelligkeit (I nahe 0) ist die der Innenraumbeleuchtung 6 zugeführte Leistung P die Nennleistung Pmax des Leuchtmittels der Innenraumbeleuchtung 6; mit zunehmender Umgebungshelligkeit I nimmt die Leistung P ab und erreicht schließlich den Wert 0, wenn die Umgebungshelligkeit einen solchen Wert erreicht hat, dass davon ausgegangen werden kann, dass diese auch zum Ausleuchten des Kühlschrankinnenraums genügt.The control electronics 3 is also connected to a switch 5 for detecting the opening or closing of the door 1. When the switch 5 indicates an open state of the door 1, the control electronics 3 supplies the interior lighting 6 with a current, the power of which it regulates as a function of the photocurrent of the photodiode 4. Examples of a possible control behavior of the control electronics 3 are shown as characteristic curves of the supply power P for the interior lighting as a function of the intensity of the ambient lighting or of the photocurrent I. In the case of low ambient brightness (I close to 0), the power P supplied to the interior lighting 6 is the nominal power Pmax of the illuminant of the interior lighting 6; With increasing ambient brightness I, the power P decreases and finally reaches the value 0 when the ambient brightness has reached such a value that it can be assumed that it is also sufficient to illuminate the interior of the refrigerator.
Die Kurve b zeigt ein entgegengesetztes Steuerverhalten: Im Falle geringer Umgebungshelligkeit (I nahe 0) wird der Innenraum zunächst mit einer geringen Leistung Pmin beleuchtet, und mit zunehmender Helligkeit nimmt auch die Beleuchtungsleistung zu, bis sie schließlich die Nennleistung Pmax erreicht, für die die Innenraumbeleuchtung 6 konzipiert ist. Dieser Art der Regelung liegt die Überlegung zugrunde, dass bei einer niedrigen Umgebungshelligkeit die Augen eines Benutzers im allgemeinen an eine solche Helligkeit akkommodiert sein werden, so dass eine zu starke Innenraumbeleuchtung ihn blenden könnte, während umgekehrt in einer sehr hellen Umgebung auch eine starke Innenraumbeleuchtung wünschenswert sein kann.Curve b shows an opposite control behavior: In the case of low ambient brightness (I close to 0), the interior is first illuminated with a low power Pmin, and with increasing brightness the lighting power also increases until it finally reaches the nominal power Pmax for which the interior lighting 6 is designed. This type of control is based on the consideration that, in the case of a low ambient brightness, the eyes of a user will generally be accommodated to such a brightness that excessive indoor lighting could dazzle him, while conversely, strong indoor lighting is also desirable in a very bright environment can be.
Welche der beiden Steuerstrategien letztlich von einem Benutzer als angenehmer und angemessener empfunden wird, kann von den Gewohnheiten des Benutzers und von den Bedingungen abhängen, unter denen der Kühlschrank aufgestellt ist. Es ist daher zweckmäßig, eine Einstellvorrichtung vorzusehen, die dem Benutzer eine Auswahlmöglichkeit zwischen den Steuerstrategien gemäß Kurve a bzw. b gewährt bzw. die das Einstellen von stufenlosen Übergängen zwischen diesen zwei Kurven, wie in Fig. 2 gestrichelt eingezeichnet, erlaubt.Which of the two control strategies is ultimately perceived by a user as more pleasant and appropriate may depend on the user's habits and the conditions under which the refrigerator is installed. It is therefore expedient to provide an adjustment device which allows the user to choose between the control strategies according to curve a or b or which allows the adjustment of stepless transitions between these two curves, as shown in dashed lines in FIG. 2.
Fig. 2 zeigt ein Gehäuse 10 für eine Innenraumbeleuchtung eines Kältegeräts, die zur Realisierung einer zweiten Ausgestaltung der vorliegenden Erfindung geeignet ist. Das Gehäuse 10 umfasst ein transparentes Gehäuseteil 11 , hinter dem ein Leuchtmittel 12 wie etwa eine herkömmliche Glühbirne oder Halogenbirne installiert ist, sowie ein opakes Gehäuseteil 13, welches die Fassung des Leuchtmittels und eine Steuerschaltung für die elektrische Leistung aufnimmt, mit der das Leuchtmittel 12 versorgt wird. Ein mit der Steuerschaltung verbundenes lichtempfindliches Element ist hinter einem Fenster 14 an einer vom Leuchtmittel 12 abgewandten Seite des opaken Gehäuseteils 13 angeordnet, so dass Licht, welches durch das Fenster 14 des in einem Kältegerät montierten Gehäuses auf das lichtempfindliche Element fällt, eine Überlagerung von durch die geöffnete Tür des Kältegeräts einfallendem Außenlicht und von der Innenraumbeleuchtung selbst erzeugtem, an den Wänden des Innenraums und nahe befindlichen Gegenständen gestreutem Licht ist.FIG. 2 shows a housing 10 for interior lighting of a refrigeration device, which is suitable for realizing a second embodiment of the present invention. The housing 10 comprises a transparent housing part 11, behind which an illuminant 12, such as a conventional light bulb or halogen bulb, is installed, and an opaque housing part 13, which receives the socket of the illuminant and a control circuit for the electrical power with which the illuminant 12 supplies becomes. A light-sensitive element connected to the control circuit is arranged behind a window 14 on a side of the opaque housing part 13 facing away from the illuminant 12, so that light which falls on the light-sensitive element through the window 14 of the housing mounted in a refrigerator is overlaid by the open door of the refrigerator and the outside light coming in Interior lighting is self-generated light that is scattered on the walls of the interior and nearby objects.
Das Gehäuse 10 bildet zusammen mit den darin enthaltenen Komponenten eine Baueinheit, die mit geringem Aufwand an der Innenwand eines Kältegerätes montierbar ist. Insbesondere genügt ein einziges Leitungspaar zur elektrischen Versorgung der gesamten Baueinheit, das durch einen Türschalter wie den Schalter 5 geschaltet wird, denn die Steuerschaltung benötigt nur genau dann einen Versorgungsstrom, wenn auch das Leuchtmittel in Betrieb ist.The housing 10 forms, together with the components contained therein, a structural unit which can be mounted on the inner wall of a refrigeration device with little effort. In particular, a single line pair is sufficient for the electrical supply of the entire structural unit, which is switched by a door switch such as switch 5, because the control circuit only requires a supply current when the lamp is also in operation.
Ein Drehschalter 15 zum Einstellen der Steigung der P/I-Kennlinie ist am Gehäuseteil 13 montiert.A rotary switch 15 for setting the slope of the P / I characteristic curve is mounted on the housing part 13.
Im Gegensatz zum mit Bezug auf Fig. 1 beschriebenen Ausführungsbeispiel, wo die Leistung der Innenraumbeleuchtung in einem offenen Kreis gesteuert wird, findet bei dieser Ausgestaltung eine Regelung im geschlossenen Kreis statt, da das lichtempfindliche Element auch von der Innenraumbeleuchtung selbst erzeugtes Licht erfasst. Dadurch ist es möglich, durch geeignete Einstellung der Steigung der P/I- Kennlinie die Gesamthelligkeit im Innenraum auf einen stets gleichbleibenden, von der Umgebungshelligkeit unabhängigen Wert zu regeln oder das Ausmaß des Zuwachses an Gesamthelligkeit im Innenraum bei zunehmender Umgebungshelligkeit vorzugeben.In contrast to the exemplary embodiment described with reference to FIG. 1, where the performance of the interior lighting is controlled in an open circuit, in this configuration regulation takes place in a closed circuit, since the light-sensitive element also detects light generated by the interior lighting itself. This makes it possible to regulate the overall brightness in the interior to a constant value that is independent of the ambient brightness, or to specify the extent of the increase in overall brightness in the interior as the ambient brightness increases, by suitably adjusting the slope of the P / I characteristic curve.
Ein weiterer, in der Fig. nicht dargestellter Regler kann zum Einstellen des P- Achsenabschnitts der P/I-Kennlinie vorgesehen werden. Another controller, not shown in the figure, can be provided for setting the P-axis section of the P / I characteristic.
