Abstract

A refrigerator with interior lighting (6), fitted with a control circuit (3) for adjusting the intensity of said interior lighting (6) according to a brightness value detected by a light-sensitive element (4).

Description

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.Refrigerators such as refrigerators or freezers are conventionally provided with interior lighting which is automatically switched on and off by a switch located on the door of the appliance.

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. Ein Kältegerät gemäß dem Oberbegriff von Anspruch 1 ist aus JP 05060458 bekannt.The bulbs currently used for the interior lighting of refrigerators actually translate only a small fraction of their electrical power consumption into light output; By far the greater part of the power consumption is converted into heat, which undesirably heats and dissipates the interior. Of course, this heat input could be avoided by dispensing with interior lighting; On the other hand, the lighting is felt to be necessary to find a searched item in the interior quickly. A refrigerator according to the preamble of claim 1 is made JP 05060458 known.

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.Object of the present invention is to provide a refrigeration device in which the heating of the interior is reduced by the illumination, without this having to be bought with a reduction in comfort for the user. On the contrary, with skillful use, the comfort for the user can even be increased.

Die Aufgabe wird gelöst durch ein Kältegerät mit Innenraumbeleuchtung und einer Steuerschaltung zum Steuern der Leistung der Innenraumbeleuchtung in Abhängigkeit von einem von einem lichtempfindlichen Element erfassten Helligkeitswert wobei die Steuerschaltung mit einem Stellglied zum Einstellen der Abhängigkeit zwischen erfasstem Helligkeitswert und Leistung der Innenraumbeleuchtung ausgestattet ist. 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 object is achieved by a refrigerator with interior lighting and a control circuit for controlling the power of the interior lighting in response to a detected by a photosensitive member brightness value wherein the control circuit is equipped with an actuator for adjusting the relationship between detected brightness value and performance of the interior lighting. By setting such an actuator, a user can customize the behavior of the control circuit to his personal needs. Thus, e.g. the control is performed such that the power of the interior lighting set by the control circuit supplements the light intensity incident from the outside, so that a substantially constant brightness in the interior is always achieved, irrespective of the brightness of the surroundings, i. the power set by the control circuit changes in opposition to a change in ambient brightness; However, it is also conceivable to control the power of the interior lighting in a manner that corresponds to the ambient brightness with the aim of achieving a brightness in the interior which is proportional to the ambient brightness to a certain extent. Namely, if the room in which the refrigeration device is set up, for example, by directly sunlit sunlight is extremely bright, and the eyes of a user adapted to this level of illumination, so he needs to find objects in the refrigerator conveniently, a higher illuminance in this, as if he looks in a twilight environment in the refrigerator.

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, the performance of the interior lighting when the ambient brightness is sufficient to illuminate the interior of the refrigerator sufficiently with the door 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 photosensitive element is arranged on an outside of the refrigerating appliance in order to directly control the intensity of the light in the refrigerator Environment of the refrigerator to capture. Preferably, the photosensitive element is located on a control panel of the refrigerator, which forms the visible side of the refrigerator together with the door and thus exposed to an ambient light intensity, which also falls into the interior of the refrigerator when the door is open. The attachment to the control panel is also preferred because it allows the wiring of the photosensitive element with the associated control circuit with little effort, together with the wiring of other controls.

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 photosensitive element is arranged in the interior of the refrigeration device so that it is exposed to the combined intensity of the interior lighting and the ambient light (when the door is open). This embodiment allows, in particular, the regulation of the performance of the interior lighting as a function of the degree of opening of the door or of 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 photosensitive element and the control circuit may be connected to the interior lighting to form a structural unit, which is mountable as a prefabricated element in the interior. The cost of mounting such an element is not higher than that for the installation of a conventional interior lighting.

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 will become apparent from the following description of exemplary embodiments with reference to the accompanying figures. Show it:

a view of a housing for an 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 is located at the front of a control panel 2, are arranged on the various, not shown in the figure setting and display elements, eg for the temperature of the interior. Behind the control panel 2 an electronic control unit 3 is housed, with which the various control and display elements are connected, and controls, for example, in a conventional manner, the operation of a (not shown) coolant circuit.

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 is mounted as a photosensitive element, a photodiode 4, which provides a representative of the brightness in the vicinity of the refrigerator photocurrent 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 (1 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 further 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 whose power is regulated as a function of the photocurrent of the photodiode 4. Examples of a possible control behavior of the control electronics 3 are shown as characteristics of the supply power P for the interior lighting as a function of the intensity of the ambient lighting or the photocurrent I. At low ambient brightness (1 near 0), the power supplied to the interior lighting 6 is P the rated power Pmax of the illuminant of the interior lighting 6; with increasing ambient brightness I decreases the power P and finally reaches the value 0 when the ambient brightness has reached such a level that it can be assumed that this is sufficient to illuminate the refrigerator interior.

Die Kurve b zeigt ein entgegengesetztes Steuerverhalten: Im Falle geringer Umgebungshelligkeit (1 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.The curve b shows an opposite control behavior: In the case of low ambient brightness (1 near 0), the interior is first illuminated with a low power Pmin, and with increasing brightness, the lighting power increases until it finally reaches the rated power Pmax, for the interior lighting 6 is designed. This type of regulation is based on the consideration that at a low ambient brightness the eyes of a user will generally be accommodated to such a brightness, so that an excessive interior lighting could dazzle him, while conversely in a very bright environment also a strong interior lighting desirable 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 as more comfortable and appropriate by a user 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 gives the user a choice between the control strategies according to curve a or b and the setting of stepless transitions between these two curves, as in Fig. 2 dashed lines, allowed.

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 an interior lighting of a refrigerator, which is suitable for implementing a second embodiment of the present invention. The housing 10 comprises a transparent housing part 11, behind which a lighting means 12 such as a conventional light bulb or halogen bulb is installed, and an opaque housing part 13, which receives the socket of the lighting means and a control circuit for the electrical power supplied to the lighting means 12 becomes. A light-sensitive element connected to the control circuit is arranged behind a window 14 on a side facing away from the bulb 12 side of the opaque housing part 13, so that light which falls through the window 14 of the housing mounted in a refrigerator on the photosensitive element, a superposition of the open door of the refrigerator incidence outside light and of the Interior lighting is self-generated, scattered on the walls of the interior and nearby objects light.

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 with little effort on the inner wall of a refrigerator. In particular, a single line pair is sufficient for the electrical supply of the entire unit, which is switched by a door switch such as the switch 5, because the control circuit only needs a supply current, even if the light source is in operation.

Ein Drehschalter 15 zum Einstellen der Steigung der P/I-Kennlinie ist am Gehäuseteil 13 montiert.A rotary switch 15 for adjusting the slope of the P / I characteristic 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.Unlike with respect to Fig. 1 described embodiment, where the performance of the interior lighting is controlled in an open circuit, takes place in this embodiment, a closed-loop control, since the photosensitive element also detects light generated by the interior lighting itself. This makes it possible to regulate the overall brightness in the interior to an always constant, independent of the ambient brightness value by appropriate adjustment of the slope of the P / I curve or to specify the extent of the increase in overall brightness in the interior with increasing ambient brightness.

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, may be provided for adjusting the P-axis portion of the P / I characteristic.
