Ein derartiges Gerät ist das allenthalben bekannte italienische Espresso-Kännchen. Dieses Kännchen wird zur Zubereitung von Espresso auf eine Kochstelle eines Gasherds oder auch auf eine Kochplatte eines Elektroherds gestellt. Das Kochgefäß eines solchen Espresso-Kännchens hat üblicherweise einen wesentlich kleineren Durchmesser als eine normale Kochplatte eines Elektroherds. Im Vergleich zur dissipierten, insbesondere abgestrahlten Wärme ist der Wärmeübergang von der Kochplatte auf das Kochgefäß sehr schlecht und damit der Energieverbrauch sehr hoch. Auch die Aufheizdauer bis das Wasser in dem Kochgefäß auf Siedetemperatur gebracht ist, ist gemessen an der Füllmenge fast unerträglich hoch, da zuerst die große Masse der Kochplatte erhitzt werden muß, bis Wärme an das Espresso-Kännchen weitergeleitet werden kann.Such a device is the well known Italian espresso jug. This jug becomes Preparation of espresso on a gas stove or placed on a hotplate of an electric cooker. The Cooking jar of such an espresso pot usually has a much smaller diameter than a normal one Cooking plate of an electric cooker. Compared to the dissipated, radiated heat in particular is the heat transfer from the Hotplate on the cooking vessel very bad and therefore the Very high energy consumption. Also the heating up time until that Water in the cooking vessel is brought to boiling temperature Measured against the filling quantity almost unbearably high, because first the large mass of the hotplate must be heated until warm can be forwarded to the espresso pot.
Es wurde bereits der Vorschlag gemacht, die Größe einer externen Heizvorrichtung in Form einer elektrischen Kochplatte auf die Größe des Durchmessers der Standfläche üblicher Espresso-Kännchen zu reduzieren. Dies ist allerdings aufwendig und erfordert den Erwerb und die Lagerung eines zusätzlichen KÜchengeräts in Form der externen Heizplatte. Auch die Handhabung beim Espresso-Kochen ist kompliziert, da nicht nur das Espresso-Kännchen zur Hand genommen werden muß, sondern zusätzlich die externe Heizplatte aus einem Küchenschrank genommen, positioniert und nach Gebrauch und hinreichendem Abkühlen wieder verstaut werden muß.The proposal has already been made, the size of a external heating device in the form of an electric hotplate to the size of the diameter of the footprint more common Reduce espresso jug. However, this is expensive and requires the purchase and storage of an additional one Kitchen appliance in the form of an external heating plate. Also the Handling when cooking espresso is complicated because not only the espresso pot has to be picked up, but additionally the external heating plate from a kitchen cupboard taken, positioned and after use and sufficient Cooling must be stowed away again.
Der vorliegenden Erfindung liegt hiervon ausgehend die Aufgabe zugrunde, ein Gerät der eingangs erwähnten Art so zu verbessern, daß der Energieverbrauch reduziert und die Zubereitungszeit verkürzt und damit auch der Bedienungskomfort erhöht wird.Based on this, the object of the present invention based on a device of the type mentioned above improve that energy consumption is reduced and the Preparation time is shortened and with it the ease of use is increased.
Diese Aufgabe wird durch ein Gerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß eine elektrische Heizeinrichtung am Kochbehälter vorgesehen ist.This task is performed by a device as described in the introduction Art solved according to the invention in that an electrical Heating device is provided on the cooking container.

Die Figur eine schematische Darstellung einer Ausführungsform eines erfindungsgemäßen Espresso-Kännchens.The figure is a schematic representation of an embodiment of an espresso jug according to the invention.
Die Figur zeigt ein erfindungsgemäßes Espresso-Kännchen. Das im Kochbehälter (1) befindliche Wasser (2) wird durch die vom Heizelement (12) zugeführte Energie bis zum Kochen erhitzt. Der entstehende Überdruck preßt das Wasser (2) über ein Steigrohr (3) durch Sieb (4), Kaffeemehl (5) und Sieb (6) über ein weiteres Steigrohr (7) in das Brühgefäß (8). Um diesen Überdruck zu erzeugen ist der Kochbehälter (1) mit dem Brühgefäß (8) druckdicht verbunden, lediglich über die Siebkammer (14) und damit durch das Kaffeemehl (5) besteht eine offene Verbindung zwischen Kochgefäß (1) und Brühgefäß (8). Wenn das gesamte Wasser (2) verdampft ist, steigt die Temperatur des Heizelements (12) an. Ein Thermostat (15) unterbricht nun die Stromzufuhr. Ein Anzeigeelement, z. B. eine Kontrollampe, signalisiert nun, daß der Zubereitungsvorgang abgeschlossen ist.The figure shows an espresso jug according to the invention. The water ( 2 ) in the cooking container ( 1 ) is heated up to the boil by the energy supplied by the heating element ( 12 ). The resulting overpressure presses the water ( 2 ) through a riser pipe ( 3 ) through sieve ( 4 ), ground coffee ( 5 ) and sieve ( 6 ) through a further riser pipe ( 7 ) into the brewing vessel ( 8 ). In order to generate this overpressure, the cooking container ( 1 ) is connected to the brewing vessel ( 8 ) in a pressure-tight manner; there is only an open connection between the cooking vessel ( 1 ) and the brewing vessel ( 8 ) via the sieve chamber ( 14 ) and thus through the coffee grounds ( 5 ). When all the water ( 2 ) has evaporated, the temperature of the heating element ( 12 ) increases. A thermostat ( 15 ) now cuts off the power supply. A display element, e.g. B. a control lamp, now signals that the preparation process is complete.
Der fertige Espresso-Kaffee (10) kann nun ausgeschenkt werden, dazu ist das Gerät vorzugsweise mit einem Griff (11) und einem Deckel (17) versehen. Bei einer Ausführung mit Kontaktsockel (16) ist das Gerät bequem abzunehmen, ohne das Netzkabel ausstecken zu müssen. Zur Absicherung des entstehenden Überdrucks ist ein Überdruckventil (13) in den Kochbehälter (1) integriert.The finished espresso coffee ( 10 ) can now be poured out, for this purpose the device is preferably provided with a handle ( 11 ) and a lid ( 17 ). In the case of a version with a contact base ( 16 ), the device can be easily removed without having to unplug the power cord. To protect the resulting overpressure, an overpressure valve ( 13 ) is integrated in the cooking container ( 1 ).
Das elektrische Heizelement (12) ist direkt auf den Boden des Kochbehälters (1) aufgebracht. Dieses Heizelement (12) kann in verschiedensten Bauarten ausgeführt sein, wie z. B. in Form eines aufgelöteten oder aufgepreßten Rohrheizkörpers oder in Form eines in Dickschichttechnik aufgebrachten Widerstandsheizelements. The electric heating element ( 12 ) is applied directly to the bottom of the cooking container ( 1 ). This heating element ( 12 ) can be carried out in various designs, such as. B. in the form of a soldered or pressed tubular heater or in the form of a resistance heating element applied in thick-film technology.
