Abstract
Transportable Kühlbox mit einem elektrisch betriebenen Kühlaggregat, einer Temperaturmesseinrichtung in einem Innenraum und einer Temperaturanzeige, wobei die Temperaturanzeige über eine LCD-Anzeige in einem Deckel der Kühlbox erfolgt, dadurch gekennzeichnet, dass die Temperaturmesseinrichtung im Deckel und in einem von einer Luftumwälzvorrichtung in dem Innenraum induzierten Luftstrom der Kühlbox angeordnet ist.Transportable cool box with an electrically operated cooling unit, a temperature measuring device in an interior and a temperature display, the temperature being displayed via an LCD display in a lid of the cool box, characterized in that the temperature measuring device in the lid and in one induced by an air circulation device in the interior Airflow of the cool box is arranged.
Description
Die Erfindung betrifft eine transportable Kühlbox mit den Merkmalen des Anspruchs 1.The invention relates to a portable cool box with the features of
Transportable Kühlboxen weisen in Abhängigkeit von verfügbarer Kühlleistung und Außentemperaturen unterschiedliche Temperaturen im Innenraum auf. Um diese Temperaturen im Innenraum zu kontrollieren wird üblicherweise der Deckel der Kühlbox geöffnet, wodurch wiederum sich der Innenraum der Kühlbox an die Umgebungstemperatur angleicht, insbesondere dann wenn diese Kontrolle häufiger durchgeführt wird.Transportable coolers have different temperatures in the interior depending on available cooling capacity and outside temperatures. In order to control these temperatures in the interior, the lid of the cooler is usually opened, which in turn adjusts the interior of the cooler to the ambient temperature, especially if this control is performed more frequently.
Bekannt ist es auch Temperaturmesseinrichtungen und eine Temperaturanzeige an der Kühlbox anzubringen, wobei die Temperaturmesseinrichtungen direkt an den Kühlelementen angebracht sind und daher in aller Regel nicht die Temperatur im Innenraum der Kühlbox, sondern einen zu niedrigen Wert angeben. Die Anzeige der Temperatur gibt zudem keine leicht ablesbaren genauen Temperaturwerte an.It is also known to install temperature measuring devices and a temperature display on the cooling box, wherein the temperature measuring devices are mounted directly on the cooling elements and therefore generally do not indicate the temperature in the interior of the cooler, but too low a value. The display of the temperature also does not indicate easily readable exact temperature values.
So offenbart z. B. die
Aufgabe der Erfindung ist es, eine transportable Kühlbox zu schaffen, mit der die Temperaturen im Innenraum der Kühlbox korrekt erfasst und genau und leicht lesbar an der Kühlbox wiedergegeben werden.The object of the invention is to provide a portable cool box, with which the temperatures recorded in the interior of the cool box correctly and reproduced accurately and easily readable on the cool box.
Die Lösung erfolgt mit einer transportablen Kühlbox mit den Merkmalen des Anspruchs 1.The solution is carried out with a portable cool box with the features of
Gemäß der Erfindung ist eine transportable Kühlbox mit einem elektrisch betriebenen Kühlaggregat, einer Luftumwälzvorrichtung, einer Temperaturmesseinrichtung und einer Temperaturanzeige ausgestattet. Die Temperaturanzeige erfolgt über eine LCD-Anzeige in einem Deckel der Kühlbox und die Temperaturmeßeinrichtung ist in einem Luftstrom in einem Innenraum der Kühlbox angeordnet. Der Luftstrom im Innenraum der erfindungsgemäßen Kühlbox sorgt für eine gleichmäßige Temperaturverteilung, so daß der von der Temperaturmeßeinrichtung im Luftstrom erfaßte Temperaturwert repräsentativ ist für die Temperatur im gesamten Innenraum. Die LCD-Anzeige ist gut sichtbar an der Außenseite der Kühlbox angeordnet und gibt exakt in digitaler Angabe die gemessenen Temperaturwerte in der erfindungsgemäßen Kühlbox wieder.According to the invention, a portable cool box is equipped with an electrically operated cooling unit, an air circulating device, a temperature measuring device and a temperature indicator. The temperature is displayed via an LCD display in a lid of the cooler and the temperature measuring device is arranged in an air flow in an interior of the cooler. The air flow in the interior of the cooling box according to the invention ensures a uniform temperature distribution, so that the temperature value detected by the temperature measuring device in the air flow is representative of the temperature in the entire interior. The LCD display is arranged clearly visible on the outside of the cool box and reproduces exactly in digital form the measured temperature values in the cool box according to the invention.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die Temperaturmeßeinrichtung im Deckel angeordnet. Mit der Anordnung der Temperaturmeßeinrichtung im Deckel wird vermieden, daß in Bereichen der Kühlbox, die von Kondenswasser beaufschlagt werden können, wie z. B. am Boden, Montagebohrungen für die Temperaturmeßeinrichtung eingebracht werden müssen, aus denen Dichtigkeitsprobleme resultieren können.According to an advantageous embodiment of the invention, the temperature measuring device is arranged in the lid. With the arrangement of the temperature measuring in the lid it is avoided that in areas of the cool box, which can be acted upon by condensation, such. B. on the ground, mounting holes for the temperature measuring must be introduced from which leakage problems can result.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die LCD-Anzeige mit einer vom elektrisch betriebenen Kühlaggregat unabhängigen Energieversorgung ausgestattet, so daß die Temperatur des Innenraums auch angezeigt wird, wenn die Kühlbox von elektrischen Versorgungssystemen getrennt ist, wie z. B. während eines Picknicks ohne Stromversorgung. Vorzugsweise erfolgt die Energieversorgung der LCD-Anzeige durch Batterien.According to a further advantageous embodiment of the invention, the LCD display is equipped with a power supply independent from the electrically operated cooling unit, so that the temperature of the interior is also displayed when the cool box is disconnected from electrical supply systems, such. B. during a picnic without power. Preferably, the power supply of the LCD display is done by batteries.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Kühlaggregat der erfindungsgemäßen Kühlbox mit einem Peltier-Element versehen.According to a further advantageous embodiment of the invention, the cooling unit of the cooler according to the invention is provided with a Peltier element.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Luftumwälzvorrichtung als doppelseitiges Gebläse im Deckel ausgebildet ist, das sowohl die kalte als auch die warme Seite des Kühlaggregats beaufschlagt.According to a further advantageous embodiment of the invention, the air circulation device is designed as a double-sided blower in the lid, which acts on both the cold and the warm side of the cooling unit.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels dargestellt.The invention is illustrated below with reference to an embodiment.
