Description

Die Erfindung betrifft ein Kühloöbel mit einer Leuchtstofflampe, die von einer Schlagschutzverkleidung umgeben ist.The invention relates to a refrigerated cabinet with a fluorescent lamp which is surrounded by an impact protection lining.

Es ist seit langem üblich, Kühlmöbel, wie z.B. Kühltruhen, Kühlregale oder Verkaufstiefkühlschränke mit Glastüren, mit Leuchtstofflampen auszustatten, um die im Kühlmöbel gelagerte oder ausgestellte Ware zu beleuchten. Leuchtstofflampen werdeh wegen ihrer gegingen Wärmeentwicklung Glühlampen vorgezogen. Zum Schutz gegen mechanische Beschädigungen beim Befüllen des Kühlmöbels durch das Bedienungspersonal, bei der Warenentnahme durch Kunden, bei Reinigungsarbeiten u.ä. ist die Leuchtstoffröhre im allgemeinen von einer Verkleidung umgeben. Die Verkleidung kann sowohl ein Rohr aus einem schlagfesten, lichtdurchlässigen Material als auch eine Metallfassung mit einer schlagfesten, lichtdurchlässigen Abdeckung sein.It has long been common practice to use refrigeration cabinets, e.g. Freezers, refrigerated shelves or freezers with glass doors, equipped with fluorescent lamps to illuminate the goods stored or displayed in the refrigerator. Fluorescent lamps are preferred to incandescent lamps due to the fact that heat is lost. To protect against mechanical damage when the refrigerator is filled by the operating personnel, when goods are removed by customers, during cleaning work, etc. the fluorescent tube is generally surrounded by a panel. The cladding can be both a tube made of an impact-resistant, translucent material and a metal frame with an impact-resistant, translucent cover.

Standardleuchtstcfflampen mit ihren nach VDE zugeordneten Vorschaltgeräten entfalten ihre volle Leuchtkraft nur bei Temperaturen von über 20° C. Es hat sich herausgestellt, daß die Leuchtkraft der Leuchtstofflampen mit sinkender Temperatur abnimmt. Bei Temperaturen, wie sie in Kühlmöbeln herrschen, beginnen die Lampen zu flackern. Als Abhilfe wurden bisher in Kühlmöbeln Hochleistungs-Leuchtstoffröhren verwendet, die jedoch zwei Vorschaltgeräte benötigen und außerdem mehr elektrische Energie verbrauchen als Standard-Leuchtstofflampen.Standard fluorescent lamps with their ballasts assigned according to VDE only develop their full luminosity at temperatures of over 20 ° C. It has been found that the luminosity of the fluorescent lamps decreases with decreasing Temperature decreases. At temperatures such as those prevailing in refrigeration units, the lamps begin to flicker. Have been as a remedy in refrigeration units Hochleistun g s fluorescent tubes used but need two ballasts, and also consume more electrical energy than standard fluorescent lamps.

Der Erfindung liegt die Aufgabe zugrunde, ein Kühlmöbel der eingangs beschriebenen Art zu entwickeln, bei dem in energiesparender Weise Standard-Leuchtstoffröhren verwendet werden und das bei allen im Kühlmöbel auftretenden Temperaturen gleichmäßig ausgeleuchtet wird.The invention has for its object to develop a refrigerator of the type described above in which standard fluorescent tubes are used in an energy-saving manner and which is uniformly illuminated at all temperatures occurring in the refrigerator.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mit der Schlagschutzverkleidung eine mit Abstand zu ihr angeordnete lichtdurchlässige luftdichte Umhüllung verbunden ist, und die Schlagschutzverkleidung und/oder die Umhüllung dicht mit der Leuchtstofflampe verbunden sind.This object is achieved in that a light-permeable airtight envelope arranged at a distance from it is connected to the impact protection cladding, and the impact protection cladding and / or the envelope are tightly connected to the fluorescent lamp.

Durch das Zusammenwirken der Umhüllung mit der Schlagschutzverkleidung wird ein luftdichter Raum geschaffen, der. eine wirksame Wärmeisolierung darstellt. Die Leuchtstofflampe ist dicht-mit der doppelwandigen Verkleidung verbunden. Die Wärme, die beim Betrieb der Leuchtstofflampe erzeugt wird, wird durch die Wärmeisolierung zurückgehalten. Somit dient die Leuchtstoffröhre selbst zur Erzeugung einer günstigen.Betriebstemperatur und es ist durch den Erfindungsgegenstand möglich, die volle Leuchtkraft von Standard-Leuchtstofflampen auch in Kühlmöbeln auszunutzen.The interaction of the casing with the impact protection lining creates an airtight space that. represents an effective thermal insulation. The fluorescent lamp is tightly connected to the double-walled cladding. The heat generated during the operation of the fluorescent lamp is retained by the thermal insulation. Thus, the fluorescent tube itself is used to generate a favorable operating temperature and the subject matter of the invention makes it possible to utilize the full luminosity of standard fluorescent lamps even in refrigerated furniture.

Die Umhüllung weist vorteilhafterweise eine der Form der Schlagschutzverkleidung ähnliche Form auf. Bei einer zweckmäßigen Ausgestaltung des Erfindungsgegenstandes ist die Umhüllung rohrförmig ausgebildet, wobei bei Verwendung einer ebenfalls rohrförmigen Schlagschutzverkleidung zwischen den beiden Rohren ein ringförmiger Isolierraum entsteht. Grundsätzlich sind aber auch andere Formen für die Umhüllung denkbar. Ist beispielsweise die Schlagschutzverkleidung in Form einer Haube auf eine Metallfassung aufgesetzt, umgibt zweckmäßigerweise auch die Umhüllung die Verkleidung haubenförmig, wobei dann allerdings noch für eine zusätzliche Wärmeisolierung der nichtumhüllten Metallfassung gesorgt sein muß.The covering advantageously has a shape similar to the shape of the impact protection cladding. In an expedient embodiment of the subject matter of the invention, the casing is tubular, an annular insulation space being used between the two tubes when a likewise tubular impact protection cladding is used arises. In principle, however, other shapes for the wrapping are also conceivable. If, for example, the impact protection cladding in the form of a hood is placed on a metal frame, the casing also expediently surrounds the casing in a hood-like manner, although additional heat insulation of the non-covered metal frame must then be provided.

Mit besonderem Vorteil ist in Weiterbildung des Erfindungsgegenstandes die Umhüllung mit einer handelsüblichen Feuchtraumfassung abgedichtet.In a further development of the subject matter of the invention, the covering is sealed with a commercially available moisture-proof frame.

In der Regel ist die zwischen Schlagschutzverkleidung und Umhüllung bestehende Luftschicht bereits zur Wärmeisolierung ausreichend, um an der Leuchtstoffröhre die für einen störungsfreien Betrieb benötigte Umgebungstemperatur zu halten. Eine noch wirksamere Wärmeisolierung läßt sich bei Bedarf dadurch herstellen, daß gemäß einer günstigen Ausführungsform des Erfindungsgegenstandes der Zwischenraum zwischen Schlagschutzverkleidung und Umhüllung evakuiert und/oder in dem Zwischenraum eine Gasfüllung vorgesehen ist, die eine kleinere Wärmeleitfähigkeit als Luft aufweist.As a rule, the air layer between the impact protection cladding and the covering is already sufficient for thermal insulation in order to maintain the ambient temperature required for trouble-free operation on the fluorescent tube. An even more effective heat insulation can be produced if necessary in that, according to a favorable embodiment of the subject matter of the invention, the space between the impact protection cladding and the covering is evacuated and / or a gas filling is provided in the space which has a lower thermal conductivity than air.

Weitere Einzelheiten der vorliegenden Erfindung werden anhand von schematisch dargestellten Ausführungsbeispielen beschrieben.Further details of the present invention are described using schematically illustrated exemplary embodiments.

Hierbei zeigen:

  • Figur 1 eine erfindungsgemäße Leuchtstofflampe,
  • Figur 2 eine modifizierte Leuchtstofflampe gemäß Figur 1.
Here show:
  • 1 shows a fluorescent lamp according to the invention,
  • FIG. 2 shows a modified fluorescent lamp according to FIG. 1.

Analoge Bauteile sind in beiden Figuren mit denselben Bezugszeichen versehen. Zur Beleuchtung von Kühlmöbeln ist eine Leuchtstofflampe 1 vorgesehen. Die Leuchtstofflampe steckt in einer Feuchtraumfassung 2. Die Leuchtstofflampe 1 ist von einer koaxial zur Lampe 1 angeordneten Schlagschutzverkleidung 3 umgeben. Erfindungsgemäß ist mit Abstand zur Schlagschutzverkleidung 3 koaxial zu dieser eine lichtdurchlässige luftdichte Umhüllung 4 angeordnet, die zusammen mit der Schlagschutzverkleidung 3 einen ringförmigen Raum um die Leuchtstofflampe bildet, der mit einer Dichtung 5 luftdicht verschlossen ist. Mit einer Dichtung 6 ist das System Leuchtstofflampe/Schlagschutzverkleidung/Umhüllung dicht mit der Feuchtraumfassung 2 verbunden und gegen den Außenraum abgedichtet. Der ringförmige Raum zwischen Schlagschutzverkleidung 3 und Umhüllung 4 bildet eine Wärmeisolierung für die Leuchtstofflampe 1. Durch die Eigenwärme der Leuchtstofflampe 1 wird an der Lampe die für die Erreichung der vollen Leuchtkraft erforderliche Temperatur erzeugt. Zur Erhöhung der wärmeisolierenden Wirkung kann in dem ringförmigen Raum ein Unterdruck hergestellt und/ oder eine Gasfüllung mit kleinerer Wärmeleitfähigkeit als Luft vorgesehen sein. Mit 7 ist ein Distanzring zur Montageerleichterung bezeichnet. Die Feuchtraumfassung umfaßt ferner eine Dichtung 8, einen Adapter 9 und eine Hülse 10.Analog components are provided with the same reference symbols in both figures. A fluorescent lamp 1 is provided for illuminating refrigerated furniture. The fluorescent lamp is in a moisture-proof socket 2. The fluorescent lamp 1 is surrounded by an impact protection cladding 3 arranged coaxially to the lamp 1. According to the invention, a translucent, airtight envelope 4 is arranged at a distance from the impact protection covering 3, which together with the impact protection covering 3 forms an annular space around the fluorescent lamp, which is sealed airtight with a seal 5. With a seal 6, the system fluorescent lamp / impact protection cladding / covering is tightly connected to the moisture-proof socket 2 and sealed against the outside. The ring-shaped space between impact protection cladding 3 and envelope 4 forms thermal insulation for the fluorescent lamp 1. The temperature required for achieving the full luminosity is generated on the lamp by the inherent heat of the fluorescent lamp 1. To increase the heat-insulating effect, a negative pressure can be produced in the annular space and / or a gas filling with a lower thermal conductivity than air can be provided. 7 with a spacer ring for ease of assembly is designated. The wet room socket further comprises a seal 8, an adapter 9 and a sleeve 10.

Figur 2.zeigt eine modifizierte Ausführungsform, die sich von Figur 1 durch die Art der Dichtung zwischen der Schlagschutzverkleidung 3 und der Umhüllung 4 unterscheidet. Die Dichtung 11 ist so geformt, daß sie zugleich als Distanzring für die Schlagschutzkleidung 3 wirkt. Der separate Distanzring kann daher entfallen.FIG. 2 shows a modified embodiment which differs from FIG. 1 by the type of seal between the impact protection lining 3 and the casing 4. The seal 11 is shaped so that it also acts as a spacer for the impact protection clothing 3. The separate spacer ring can therefore be omitted.

Selbstverständlich ist es nicht erforderlich, daß die Umhüllung 4 und die Schlagschutzverkleidung 3 kreisförmige Querschnitte aufweisen, entscheidend ist, daß zwischen beiden ein luftdichter, dicht mit der Leuchtstofflampe 1 verbundener Isolierraum geschaffen ist.Of course, it is not necessary for the covering 4 and the impact protection cladding 3 to have circular cross sections, it is crucial that an airtight insulating space tightly connected to the fluorescent lamp 1 is created between the two.
