Abstract

The coffee machine for the prodn. of filter coffee has a special feature, so that the coffee powder with the assistance of an electric motor with an eccentric or similar working device, is subjected to vibrations or shaking. The system can be an electric motor with an eccentric or cam, which makes contact with the filter or the complete coffee machine, and displaces it in vibrations, and a contact breaker, similar to the known knife switch. A sound transmitter can be aligned on the powder, or a vibrating body is dipped in the coffee filter.

Description

Bei der Herstellung von Filterkaffee wird üblicherweise so vorgegangen, daß heißes Wasser von oben auf das Kaffeepulver tropft. Dabei wird das Pulver in der Filtermitte und am Filterboden stärker mit Wasser durchtränkt als das Pulver am oberen äuße­ ren Filterrand. Die Folge ist, daß das Pulver nicht optimal ausgenutzt wird. Das zeigt sich auch daran, daß nach dem "Kaffeekochen" das Pulver im Filter sehr ungleich­ mäßig verteilt ist: in der Filtermitte ist eine Vertiefung, fast das gesamte Pulver haftet am Filterrand.In the production of filter coffee, the usual procedure is that hot Water drips onto the ground coffee from above. The powder is in the middle of the filter and more saturated with water on the filter bottom than the powder on the upper outside filter edge. The result is that the powder is not used optimally. This shows also remember that after "making coffee" the powder in the filter is very uneven is moderately distributed: there is a depression in the center of the filter, almost all of the powder adheres at the filter edge.

Eine besser Ausnützung wäre gegeben, wenn das gesamte Pulver immer unter der Wasseroberfläche bleiben würde.A better use would be made if the entire powder was always under the Water surface would stay.

Dies erreicht man dadurch, daß das Pulver Erschütterungen ausgesetzt ist, die es immer wieder nach unten sacken lassen.This is achieved by exposing the powder to vibrations that it let it sink down again and again.

Solche Vibrationen können durch unterschiedlichste Verfahren erzeugt werden.Such vibrations can be generated by a wide variety of methods.

Bild 1 zeigt eine Variante mit Elektromotor, der über einen Exzenter an die Kaffeemaschine oder den Filter "klopft" Figure 1 shows a variant with an electric motor that "knocks" on the coffee machine or the filter via an eccentric

Bild 2 zeigt eine Variante mit Elektromagnet, ähnlich der bekannten Klingelschaltung, bei der ein Klöppel bei Stromdurchfluß angezogen wird. Dabei unterbricht er selbst den Stromkreislauf und kehrt in die Ruhelage zurück, so daß der Strom wieder fließt usw. Der Klöppel schlägt an das Gehäuse. Figure 2 shows a variant with an electromagnet, similar to the known bell circuit, in which a clapper is attracted when current flows through it. He interrupts the circuit himself and returns to the rest position so that the current flows again, etc. The clapper hits the housing.

Bei Bild 2 übernimmt der Filteraufnahmebehälter die Aufgabe des Klöppels.In Figure 2, the filter receptacle takes on the role of the bobbin.

Kaffeemaschine zur Herstellung von Filterkaffee mit der Besonderheit, daß das Kaffeepulver mit Hilfe eines Elektromotors mit Exzenter (oder einer ähnlich wirkenden Vorrichtung) Vibrationen (oder Erschütterungen) ausgesetzt wird.Coffee machine for the production of filter coffee with the peculiarity that the coffee powder using an electric motor with an eccentric (or similar) acting device) is exposed to vibrations (or shocks). Die Vorrichtung kann ein Elektromotor mit Exzenter sein, der den Filter oder die komplette Kaffeemaschine berührt und somit in Schwingungen (Vibrationen) versetzt oder eine Anordnung mit Elektromagnet und Unterbrecher, ähnlich der bekannten Klingelschaltung.The device can be an electric motor with an eccentric, the filter or the touches the entire coffee machine and thus vibrates or an arrangement with an electromagnet and a breaker, similar to the known one Bell switch. Denkbar ist auch ein Schallsender, der auf das Kaffeepulver gerichtet ist oder ein vibrierender Körper, der in den Kaffeefilter getaucht wird.A sound transmitter is also conceivable, which is aimed at the coffee powder or a vibrating body that is immersed in the coffee filter.
