Kaffeemaschinecoffee machine
Die Neuerung bezieht eich auf eine Kaffeemaschine mit einem elektrischen Durchlauferhitzer, der aus einer wasserführenden Rohrschlange und einem Rohrheizkörper "besteht. Bei elektrischen Kaffeemaschinen besteht das Bedürfnis, die Brühzeit möglichst kurz zu halten. Dies setzt eine möglichst rasche Erhitzung des BrUbwassers voraus, die weitgehend vom Wärmeübergang von der Wärmequelle zu dem zu erhitzenden Wasser abhängt.The innovation relates to a coffee machine with a Electric instantaneous water heater, which consists of a water-carrying pipe coil and a tubular heating element ". In the case of electric Coffee machines need to keep the brewing time as short as possible. This means that the boiling water is heated as quickly as possible which largely depends on the heat transfer from the heat source to the water to be heated.
Dieser Wärmeübergang wird bei bekannten Kaffeemaschinen der eingangs beschriebenen Art dadurch verzögert, daß zwischen der wasserr führenden Rohrschlange und dem Rohrheizkörper Zwischenglieder, z.B. metallische Stege, angeordnet sind.This heat transfer is delayed, in known coffee machines of the type described initially characterized in that disposed between the water leading pipe coil r and the heating element intermediate members, for example metal bars.
Neuerungsgemäß läßt sich ein rascherer Wärmeübergang bei derartigen Kaffeemaschinen dadurch erzielen, daß die wasserführende Rohrschlange und der Rohrheizkörper in unmittelbarem Wärmekontakt stehen. Besonders vorteilhaft ist es, wenn der Rohrheizkörper und die wasserführende Rohrschlange in einer gemeinsamen Hut eingelegt sind, die auf der Unterseite einer Warmhalteplatte für eine Kaffeekanne angeordnet ist und deren Bemessung so gewählt ist, als zwischen Rohrheizkörper und Rohrschlange ein guter unmittelbarer Wärmekontakt besteht.According to the innovation, a faster heat transfer can be achieved with such Coffee machines achieve that the water-bearing pipe coil and the tubular heating element in direct thermal contact stand. It is particularly advantageous if the tubular heating element and the water-carrying pipe coil are placed in a common hat are, which is arranged on the underside of a hotplate for a coffee pot and whose dimensioning is chosen when there is good direct thermal contact between the tubular heating element and the pipe coil.

Auf der Unterseite einer Warmhalteplatte 1 für eine nicht dargestellte Kaffeekanne ist eine von Stegen 2,3 begrenzte Rut 4 vorgesehen, in die ein elektrischer Rohrheizkörper 5 und eine das Brühwasser führende Rohrschlange 6 eingelegt sind. Die Wandungen des Rohrheizkörpers 5 und der Rohrschlange 6 sind, wie Fig. 2 zeigt, auf den sich zugewandten Seiten abgeflacht, so daß sich eine verhältnismäßig große Kontaktfläche zwischen diesen beiden Elementen ergibt, die einen guten Wärmeübergang vom Rohrheizkörper 5 zur Rohrschlange 6 zur Folge hat. Die den Wandungen der Nut 4 zugewandten Flächenteile des Rohrheizkörpers 5 und der Rohrschlange 6 sind so ausgebildet, daß sie möglichst ohne Zwischenraum anliegen.On the underside of a warming plate 1 for a coffee pot, not shown, a channel 4 delimited by webs 2, 3 is provided, into which an electric tubular heating element 5 and a pipe coil 6 carrying the brewing water are inserted. The walls of the tubular heater 5 and the coil 6 are, as Fig. 2 shows, flattened on the facing sides, so that there is a relatively large contact surface between these two elements, which has a good heat transfer from the tubular heater 5 to the coil 6 result . The surface parts of the tubular heater 5 and the coil 6 facing the walls of the groove 4 are designed so that they rest as closely as possible without a gap.
