Description

Die Erfindung betrifft eine elektrisch betriebene Kühlbox, die von Hand tragbar ist und die bevorzugt im Urlaub, am Strand oder am Badesee Ver­ wendung findet.The invention relates to an electrically operated cool box made by hand is portable and preferred on vacation, on the beach or at the Ver lake turns.

Bekannte Kühlboxen dieser Art sind auf externe Stromquellen angewiesen. Dies erweist sich dann als Nachteil, wenn beispielsweise an einem Badesee keine derartige Stromquelle vorhanden ist. Auch die Möglichkeit, den Ziga­ rettenanzünder eines Autos als Stromquelle zu nutzen kann nur dann bean­ sprucht werden, wenn das Auto auch in der Nähe geparkt ist.Known cool boxes of this type rely on external power sources. This proves to be a disadvantage if, for example, at a swimming lake there is no such power source. Also the possibility of the Ziga Only then can a car's lighter socket be used as a power source if the car is parked nearby.

Es ist Aufgabe der Erfindung, eine Kühlbox der eingangs genannten Art so weiterzuentwickeln, dass diese nicht ausschließlich auf eine externe Strom­ quelle angewiesen ist. Ferner soll die zu entwickelnde Kühlbox in der Lage sein, auf verstärkte Sonneneinstrahlung auch mit verstärkter Kühlleistung zu reagieren.It is an object of the invention to provide a cool box of the type mentioned to further develop that this is not solely based on an external electricity source is instructed. Furthermore, the cool box to be developed should be able to be towards increased solar radiation even with increased cooling capacity react.

Die Lösung der Aufgabe besteht darin, dass die Kühlbox mit wenigstens einer Stromquelle in Form von Solarzellen ausgestattet ist.The solution to the problem is that the cool box with at least a power source in the form of solar cells.

Die vorgeschlagene Kühlbox nutzt den Umstand, dass Kühlboxen eigentlich nur dann Verwendung finden, wenn zu kühlende Speisen und Getränke vor Sonneneinstrahlung und damit vor starker Wärme geschützt werden sollen. Da nun Solarzellen als ausschließliche oder als weitere Stromquelle vor­ handen sind, nutzen die Solarzellen die ohnehin vorhandene Sonnenein­ strahlung und erzeugen um so mehr Strom, je stärker die Sonneneinstrah­ lung wirkt. Es lässt sich daher bei zunehmender Wärme nicht nur die Kühl­ leistung der Kühlbox steigern, sondern die so gestaltete Kühlbox ist ein au­ tarkes System, das bei Sonneneinstrahlung auch ohne externe Stromquelle auskommen kann. Diese Eigenschaft steigert den Kühlkomfort und die An­ wendbarkeit der erfindungsgemäßen Kühlbox in erheblichem Maße. Letzt­ endlich lässt sich mit der vorgeschlagenen Kühlbox auch Netzstrom sparen. The proposed cool box takes advantage of the fact that cool boxes actually only be used if food and drinks to be cooled are available Sun exposure and thus should be protected from excessive heat. Since solar cells now exist as an exclusive or additional power source are available, the solar cells use the sunshine that is already there radiation and generate more electricity the stronger the sun's rays lung works. Therefore, not only the cooling can be done with increasing heat increase the performance of the cool box, but the cool box designed in this way is an au strong system that works even in the sun without an external power source can get by. This property increases the cooling comfort and the on Applicability of the cool box according to the invention to a significant extent. last Finally, the proposed cool box can also save mains electricity.  

Es erweist sich als vorteilhaft, die Solarzellen auf dem Deckel der Kühlbox anzuordnen. Noch vorteilhafter ist es, die Solarzellen am Deckel auf einer Platte anzubringen, die sich um eine horizontale Achse nach oben ver­ schwenken lässt, während der Deckel natürlich geschlossen bleibt. Die So­ larzellen können somit in eine zur Sonne geneigte Lage geschwenkt werden, so dass sich der Wirkungsgrad der Solarzellen noch erheblich steigern lässt.It turns out to be advantageous to put the solar cells on the lid of the cool box to arrange. It is even more advantageous to have the solar cells on the cover on a Attach plate that ver up about a horizontal axis can pivot, while the lid of course remains closed. The sun lar cells can thus be swiveled into a position inclined to the sun, so that the efficiency of the solar cells can be increased significantly.

Die Erfindung wird anhand von zwei Ausführungsbeispielen näher erläu­ tert. Es zeigtThe invention is explained in more detail using two exemplary embodiments tert. It shows

Fig. 1 eine Kühlbox sowie Fig. 1 a cool box as well

Fig. 2 eine Kühlbox, bei der die Solarzellen auf einer schwenkbaren Platte angeordnet sind. Fig. 2 is a cool box, in which the solar cells are arranged on a pivotable plate.

Die in Fig. 1 dargestellte Kühlbox 1 weist ein mit einem Kühlraum 3 ausge­ stattetes Gehäuse 2 auf, das von oben her durch einen bevorzugt schwenk­ baren Deckel 5 verschließbar ist. Die Kühlbox 1 ist von Hand tragbar und eignet sich insbesondere zum Mitnehmen in den Urlaub. Sie lässt sich beim Baden oder auf dem Campingplatz verwenden. Die Kühlbox 1 trägt eine nicht näher dargestellte Kühleinrichtung 4, die imstande ist, den Kühlraum 3 zu kühlen. Die Kühleinrichtung 4 wird elektrisch betrieben, wobei sich als Kühlelemente insbesondere die sogenannten "Peltier-Elemente" eignen. Dies schließt jedoch nicht aus, dass auch andere Kühlelemente bekannter Bauart Verwendung finden können. Um der Kühleinrichtung 4, die sich im Deckel 5 und/oder im Gehäuse 2 befindet, auch ohne externe Stromquelle den erforderlichen Strom zu liefern, sind an einem Teil der Außenfläche 6 der Kühlbox 1 bekannte Solarzellen 7 vorgesehen, welche das Sonnenlicht in elektrischen Strom umwandeln. Die Solarzellen 7 sind mit der Kühlein­ richtung 4 elektrisch geschaltet, so dass der von den Solarzellen 7 erzeugte elektrische Strom von der Kühleinrichtung 4 genutzt wird, um eine stetige Kühlung des Kühlraumes 3 zu bewirken. Im Beispiel befinden sich die So­ larzellen 7, die somit wenigstens eine Stromquelle bilden, als elektrische Baueinheit gestaltet auf dem Deckel 5 der Kühlbox 1. The cooler 1 shown in Fig. 1 has an out with a cooling chamber 3 stattetes casing 2 from above is here closed by a preferably pivoting cash cover 5. The cool box 1 is portable and is particularly suitable for taking with you on vacation. It can be used when bathing or at the campsite. The cool box 1 carries a cooling device 4 , not shown, which is able to cool the cooling room 3 . The cooling device 4 is operated electrically, the so-called "Peltier elements" being particularly suitable as cooling elements. However, this does not exclude that other cooling elements of a known type can also be used. In order to supply the cooling device 4 , which is located in the cover 5 and / or in the housing 2 , even without an external power source, known solar cells 7 are provided on a part of the outer surface 6 of the cooling box 1 , which convert the sunlight into electrical current , The solar cells 7 are electrically connected to the Kühlein device 4 , so that the electrical current generated by the solar cells 7 is used by the cooling device 4 to effect a constant cooling of the cooling room 3 . In the example, the solar cells 7 , which thus form at least one power source, are designed as an electrical unit on the cover 5 of the cool box 1 .

Gemäß der Erweiterung zeigt Fig. 2 eine Kühlbox 1, die genauso funktio­ niert wie jene in Fig. 1 beschrieben. Bei diesem Ausführungsbeispiel sind die Solarzellen 7 an der Oberseite 9 des Trägers, beispielsweise einer Platte 8 angeordnet, die sich auf dem Deckel 5 befindet und die um eine horizon­ tale Achse 10 nach oben verschwenkbar ist, wobei zumindest eine nicht näher dargestellte Rasteinrichtung einfachster Art vorhanden ist, die es er­ laubt, die Platte 8 und damit die Solarzellen 7 in einer schrägen Lage zur Sonne ausgerichtet zu arretieren. Die Platte 8 lässt sich nach Lösen der Ar­ retiereinrichtung wieder auf die Ebene des Deckels 5 herabsenken und dort ebenfalls arretieren.According to the extension, FIG. 2 shows a cool box 1 , which functions in exactly the same way as that described in FIG. 1. In this embodiment, the solar cells 7 are arranged on the top 9 of the carrier, for example a plate 8 , which is located on the cover 5 and which can be pivoted upwards about a horizontal axis 10 , at least one simple-type latching device not shown is that it allows the plate 8 and thus the solar cells 7 to be locked in an oblique position aligned with the sun. The plate 8 can be lowered after loosening the Ar locking device back to the level of the lid 5 and also lock there.

Bei beiden beschriebenen Ausführungsbeispielen kann am Deckel 5 eine nicht näher dargestellte lageveränderbare Abdeckung vorgesehen sein, die zum Schutz der Solarzellen 7 bei Nichtgebrauch bestimmt ist. Soll auf die Solarzellen 7 die Sonne einwirken, lässt sich die Abdeckung entweder weg­ schwenken oder entfernen. Natürlich kann bei beiden Ausführungsbeispie­ len ein separater Stromanschluss vorgesehen sein, durch den man mit Hilfe einer externen Stromquelle die Kühlbox 1 auch zu Hause noch vorkühlen kann. Als geeignetes Mittel bietet sich hier ein auf geeignete Weise gestal­ tetes Stromkabel an, in welches ein Trafo dazwischengeschaltet ist. Eine derart vorgekühlte Kühlbox 1 kann anschließend auf die Reise oder zum Baden usw. mitgenommen werden, wo dann, wie bereits beschrieben, die Solarzellen 7 ihre Wirkung entfalten können und für permanente Kühlung sorgen.In both of the exemplary embodiments described, a position-changeable cover (not shown in more detail) can be provided on the cover 5 , which cover is intended to protect the solar cells 7 when not in use. If the sun is to act on the solar cells 7 , the cover can either be pivoted away or removed. Of course, a separate power connection can be provided in both embodiments, through which the cool box 1 can also be pre-cooled at home with the help of an external power source. A suitable means here is a suitably designed power cable, in which a transformer is interposed. Such a pre-cooled cool box 1 can then be taken on a trip or for bathing, etc., where, as already described, the solar cells 7 can then take effect and ensure permanent cooling.
