Description
Elektrisch beheizbarer Wärmebehälter für Speisen.Electrically heatable warming containers for meals.
Häufig ist es notwendig, in Küchen zubereite— te warme Speisen an von den Küchen entfernter liegende Plätze zu transportieren} sie dort zunächst zu lagern und erst später den Verbrauchern zu servieren. Diese Notwendigkeit ergibt sich insbesondere bei solchen warmen Speisen, die den Gästen von Verkehrsflugzeugen während des kluges angeL^ten werden. Um ein zu starkes Abkühlen der Speisen zu verhüten, wurden tragbare Warmhaltebehälter geschaffen, die aus einem Innen- und einem Aussenbehälter bestehen und neben wärmedämmenden Stoffen zwischei Innen- und Aussenbehälter an der Aussenwand des Innenbehälters eine elektrische Heizung aufweisen, die in dar Regel aus Rohrheizkörpern, besteht, denen der Strom aus dem am Verbraucherort vorhandenen elektrischen Versorgungsnetz zugeführt wird. Auf diese Weise wird es ermöglicht, nicht nur etwaige während des Transports entstandene Wärmeverluste auszugleichen, sondern auch die Speisen beliebig lange Zeit auf der Temperatur zu halten oder wieder auf die Temperatur anzuheben, welche die Speisen unmittelbar nach ihrer Fertigstellung in der Küche hatten.It is often necessary to transport in kitchens zubereite- te hot meals to more distant from the kitchens lying places them} there initially to store and serve consumers later. This necessity arises in particular with those warm dishes that are aimed at the guests of airliners during the wise period. In order to prevent the food from cooling down too much, portable warming containers were created which consist of an inner and an outer container and, in addition to heat-insulating materials between the inner and outer containers, have an electric heater on the outer wall of the inner container, which usually consists of tubular heaters, consists, to which the current is supplied from the electrical supply network at the point of use. In this way it is possible not only to compensate for any heat losses that may have occurred during transport, but also to keep the food at the same temperature for any length of time or to raise it back to the temperature that the food had in the kitchen immediately after its completion.
Die bisher gebräuchlichen beheizbaren Wärmebehälter haben sich zwar durchaus bewährt, sie haben aber den Nachteil, daß die Montage der aus Rohrheizkörpern bestehenden Beheizung zeitraubend und teuer ist, ferner den, daß ihr Energiebedarf verhältnismässig groß ist, dies deshalb, weil wegen des unvollkommenen Anliegens des Rohrheizkörpers die Wärmeübertragung auf den Innenbehälter nur mangelhaft ist.The previously used heatable warming containers have proven their worth, but they have the Disadvantage that the assembly of the heating consisting of tubular heaters is time-consuming and expensive, also that their energy requirements is relatively large, because the heat transfer due to the imperfect fit of the tubular heater on the inner container is insufficient.
Diese Nachteile werden durch einen Wärmebehälter beseitigt, dessen Innenbehälter gemäß der Neuerung an seiner Aussenwand ganz oder z.T. mit einem mit Isolierfolien isolierten dünnwandigen Flächenheizleiter versehen ist, der aus einem aus einem Graphit-Rußgemisch hergestelltem Widerstandsmaterial besteht, dessen Träger ein geeignetes temperaturbeständiges These disadvantages are eliminated by a heating container, the inner container of which is based on the innovation its outer wall is completely or partially provided with a thin-walled surface heating conductor, insulated with insulating foils, which consists of a resistor material made from a graphite-carbon black mixture consists, whose carrier is a suitable temperature-resistant
Gewebe ist. Die Stromzuführung zum Flächenheizieiter erfolgt über an ihm befestigte Kupferleiter, z.B. aufgenähte Kupferbänder, die mit der an der Aussenbehälterwand befestigten Gerätesteckvorrichtung verbunden sind. Der Flächenheizieiter ist auf die Aussenwand des Innenbehälter aufgeklebt, sodafi die Wärmeübertragung gleichmäßig durch seine ganie fläche erfolgt, sodaß die Aufheizzeit kurz und der Energiebedarf wesentlich geringer ist als bei Benutzung der bisher gebräuchlichen Beheizungen.Tissue is. The power supply to the surface heater takes place Via copper conductors attached to it, e.g. sewn on copper strips that are attached to the outer container wall Device connector are connected. The surface heating element is glued to the outer wall of the inner container, so it is the heat transfer evenly through its ganie surface takes place, so that the heating-up time is short and the energy requirement is significantly lower than when using the heating systems that have been used up to now.
Es ist zweckmässig, die Isolierfolie des Flächenheizleiters selbstklebend auszubilden. Die Höh· der Leistung des Heizleiter^ kann den Jeweiligen Bedürfnissen entsprechend gewählt werden. Sie wird durch sein· Abmessungen und durch die Art des G*fciiit-Ruߣeeischee bestirnt.It is advisable to make the insulating film of the surface heating conductor self-adhesive. The height Performance of the heating conductor ^ can meet the respective needs be chosen accordingly. It is determined by its dimensions and by the nature of the G * fciiit-soot.
In der Zeichnung ist ein Ausführungebeispiel des Gegenstandes der Neuerung dargestellt· Mit 2 ist der Innenbehälter und mit 3 der Aussenbehälter des Wäraebehälters bezeichnet. Der Flächenheizieiter 5 ist auf die Aussenwand des Innenbehälters 2 aufgeklebt. 4- ist ein wärmedämmender Stoff, z.B. Glaswolle, der zwischen Innen- und Aussenbehälter angeordnet ist.The drawing shows an exemplary embodiment of the subject of the innovation. With 2 is the inner container and with 3 the outer container of the Wäraebehälters. The surface heater 5 is on the The outer wall of the inner container 2 is glued on. 4- is a heat-insulating material, e.g. glass wool, which is placed between the interior and the Outer container is arranged.
