Abstract

The floating refrigerator is used for example, for providing cool, refreshing drinks for swimming pool parties. The electrically powered refrigerator ensures refrigeration over long periods of time. the heat is pumped by electric current from the refrigerator container and directed, together with inherent heat losses of the system to the surrounding water through the housing walls. The container with good thermal conductivity contains drinks. A number of cooling elements are fitted on the container and they direct heat to the outer wall of the system once the heat reaches the water. The foam plastics insulation prevents heat losses. The system is powered by direct current from a battery or from the mains via a rectifier. The low voltage used is not dangerous in this application.

Schwimmfähiger Kühler mit PeltierelementenFloatable cooler with Peltier elements

Die Erfindung betrifft einen schwimmfähigen Kühler, der beispielsweise zur Erfrischung der Gäste einer "Pool—Party" mit gekühlten Getränken dienen kann.The invention relates to a buoyant cooler, for example can be used to refresh the guests of a "pool party" with chilled drinks.

Es sind bereits Vorrichtungen ähnlicher Art bekannt. Es gibt zum Beispiel gut isolierte, schwimmfähige Behälter, die mit Eisstückchen Getränke kühlen oder vorgekühlte Getränke kühl halten. Die Kühlwirkung dieser Anordnungen sind jedoch zeitlich sehr begrenzt.Devices of a similar type are already known. There are, for example, well-insulated, buoyant containers with pieces of ice Cool drinks or keep pre-chilled drinks cool. However, the cooling effect of these arrangements is very limited in time.

Die vorliegende Erfindung betrifft nun eine zeitlich unbegrenzte Kühlwirkung durch Anwendung des an und für sich lange bekannten Peitiereffektes, indem man mit Hilfe des elektrischen Stromes aus der zu kühlenden Seite (Kühlbehälter) Wärme puapt und diese zusammen mit der sich aus den Verlusten der Peltierpumpe ergebende Wärme über einen äusseren Behälter an das umgebende Wasser abgibt.The present invention relates to a cooling effect which is unlimited in time by using what has been known per se for a long time Whip effect by puapting heat with the help of the electric current from the side to be cooled (cooling container) and putting these together with the heat resulting from the losses of the Peltier pump is given off to the surrounding water via an outer container.

Die Wirkungsweise sei anhand des folgenden Ausführungsbeispiels und der Fig. 1 näher erläutert.The mode of operation will be explained in more detail with reference to the following exemplary embodiment and FIG. 1.

In einem zum besseren Temperaturausgleich gut wärmeleitenden Behälter 1 ist das zu kühlende Gut 2 eingebracht. An den Behälter werden, je nach der erforderlichen Kühlleistung, eines oder mehrere Peltierelemente 3 angebracht, welche die Wärme des zu kühlenden Behälters 1 an die Wandung eines zweiten, ebenfalls gut wärmeleitenden schwimmfähigen Behälters 4 und von diesem in das umgebende Wasser pumptn. Dieser Behälter 4 kann zum Erreichen einer besseren Schwerpunktslage mit einem Auftriebskörper .versehen sein.In a container that conducts heat well for better temperature equalization 1, the item 2 to be cooled is introduced. Depending on the required cooling capacity, one or more can be attached to the container Peltier elements 3 attached, which the heat of the to be cooled Container 1 to the wall of a second, also highly thermally conductive buoyant container 4 and from this into the surrounding area Pumping water. This container 4 can be used to achieve a better center of gravity with a buoyancy.

Zur Verhinderung von Wärmeverlusten ist der Zwischenraum 6 zwischen Behälter 1 und Behälter 4 mit einem Kunststoffschaum gefüllt. Die zum Betrieb der Peltierelemente 3 notwendige elektrische Leistung wird über ein Kabel 5 zugeführt und kann wahlweise einer Autobatterie 7 oder über ein passendes Gleichrichter—Netzgerät-8 dem Stromnetz entnommen werden.To prevent heat loss, the space 6 is between Container 1 and container 4 are filled with a plastic foam. The electrical power required to operate the Peltier elements 3 is supplied via a cable 5 and can optionally a car battery 7 or a suitable rectifier power supply unit 8 taken from the power grid.

Da die Peltierelemente 3 mit kleiner Spannung betrieben werden (ca. 3 V pro Element), ist eine Gefährdung durch elektrischen Strom nicht gegeben.Since the Peltier elements 3 are operated with a low voltage (approx. 3 V per element), there is no risk of electrical current.

Selbstverständlich ist die Anwendung des Kühlers nicht auf Swimmingpools begrenzt, sondern kann auch beispielsweise beim Picknick am See, beim Angelen oder beim Wochenende auf dem Boot verwendet werden. Ebenso können natürlich auch Nahrungsmittel, gefangene Fische oder dergl. gekühlt werden.Of course, the application of the cooler is not on swimming pools limited, but can also be used, for example, at a picnic by the lake, when fishing or at the weekend on the boat will. Food, caught fish or the like can of course also be cooled.
