Description

The invention relates to an espresso pot and a mounting kit for retrofitting a commercial one Espresso pot. The invention further relates to an espresso jug, which with an assembly kit according to the invention is equipped.

In contrast to "normal" filter coffee, on the boiling water is poured and that has time harmful and while going through taste not desired Solving substances comes the water or steam when preparing espresso only very briefly in contact with the espresso powder. The water will pressed through the espresso powder at high pressure and takes significantly less harmful Substances such as caffeine and bitter substances. espresso is for this reason also much more tolerable, heart and stomach friendly as "normal" filter coffee.

There are different types of espresso machines. Under espresso jug or mocha jug is meant in the sense of this Invention a device made of aluminum or stainless steel, which is used for cooking of espresso after it is filled is simply placed on a stove. Espresso cans These types are widely used as an inexpensive alternative to professional espresso machines or vending machines. Jugs of this type consist of several parts. In the lower part can water and in a funnel-like insert, which in the lower part is used, the espresso powder can be filled. In the upper part, which has a spout and a lid the finished drink is collected. The lower and the upper part are threaded together screwed.

To make espresso, the water heated in the lower part. The resulting steam presses it boiling water through the funnel-shaped insert and so through the espresso powder in the upper part of the jug. For espresso the powder becomes more roasted Beans used as for normal coffee. The classic espresso blend consists of the Arabica and Robusta beans.

The production of cappuccino is based on espresso. This is diluted with milk foam and can be made as desired be sweetened with sugar. The milk foam can be prepared in two ways:

• - foaming: Hot steam is about a tube passed into a saucepan with milk. At the end of the tube is usually located a special nozzle, which distributes the steam. The milk is heated by the steam and whirled up, this leads causing the milk to foam.
• - Crack open: heated Milk (approx. 70 ° C) is opened in a special container. By moving a fine network up and down, air gets under the hot milk whirled and foam is created. This foam is mostly something fine-pored than the foam of milk, which with hot steam frothed has been.

The classic described above Espresso pot is for the preparation of a cappuccino is not suitable as it is not in is able to froth milk. Therefore, there is another device for frothing milk required or a considerably expensive professional espresso machine, like they do in cafes or restaurants is used.

In the EP 0 607 765 B1 (= De 693 12 670 T2 ) describes an espresso pot that is suitable for cooking espresso and frothing milk. The lower part of this jug is mechanically much more complex than a conventional espresso jug. It is divided into two chambers for receiving water, a piston driven by the water vapor from the outer chamber pushing the water of the central chamber through the espresso powder. This "indirect" way of pushing the water through the espresso powder into the upper part is to ensure a gentler espresso preparation. The water vapor that is created in the outer chamber can not only function but also move the piston via a nozzle for foaming Milk are used EP 0 607 765 B1 described espresso jug is a completely independent device which, like a separate device for frothing milk, must be purchased in addition to an existing espresso jug.

Based on this state of the art it is an object of the present invention to provide an espresso pot disposal to ask which besides brewing espresso while minimizing the effort of foaming of milk is suitable and on the simple and inexpensive Construction of a conventional one Espresso pot based. additionally the invention provides a mounting kit that allows a commercial espresso pot to be simple and inexpensive Way to convert that them afterwards also suitable for frothing milk is. One equipped or converted in this way Espresso jug is also the subject of the invention.

This object is achieved by the features listed in claims 1 and 3. For an espresso jug consisting of an upper part ( 13 ) with lid and a lower part ( 16 ) into which a funnel-shaped insert ( 17 ) is introduced, with the upper part ( 13 ) and lower part ( 16 ) via a thread ( 14 ) are screwed together, the invention provides that

• - The lower part for filling and heating water through a cup-shaped insert, which is connected to the outside of the upper half of the funnel shaped insert is flush and extends to the bottom of the lower part, is divided into two separate chambers, and
• - yourself on the outside of the lower part a steam pipe with a steam tap for metered draining of a steam jet, wherein
• - the Steam pipe is pressure-tight and tight with the lower part by suitable means connected is.

In preliminary experiments to develop the espresso jug according to the invention could be shown that in the lower part of a conventional The steam pressure generated by the espresso pot is sufficient to froth milk. aim the invention was therefore to provide an espresso pot, which allows this steam to flow in with minimal effort the lower part of the machine, also for foaming To use milk. So it is basically possible with an espresso pot, in which the lower part of the funnel-shaped insert has been shortened, after boiling the espresso, enough steam to froth To get milk. But this steam escapes through the chimney, through which the espresso was previously pressed. Therefore, it changes color Milk foam when using the fireplace to drain the water vapor brown due to espresso scraps.

Through the measures according to the invention however it allows with a simple espresso pot milk foam without discoloration manufacture. This is made possible by the lower part the espresso pot is divided into two chambers using the simplest of means becomes. So the water that heats up in the inner chamber will be used for cooking espresso and the water of the outer chamber for foaming of milk. The construction according to the invention ensures that just a few moves for the production of a cappuccino is necessary and no discoloration of the milk foam occur. In addition, an espresso pot according to the invention is distinguished by a simple construction. This has advantages with the Cost of an espresso pot according to the invention as well as maintenance and repair, especially under hygienic Aspects.

The assembly kit for converting a usual Espresso pot consists of

• - one Mug with the outside of the funnel-shaped Insert flush concludes and its height so chosen is that it extends to the bottom of the lower container, as well
• - one Steam pipe, which has a steam nozzle on one side and on a steam tap on the opposite side, and
• - Means around a precisely fitting hole for the steam pipe ( 11 ) in the lower part ( 16 ) to drill, and
• - means for fastening the steam tap to the lower container of the Espresso pot.

The assembly kit according to the invention makes it possible to convert a commercially available espresso pot in a very simple way so that with this afterwards Not only can espresso be cooked, but milk can also be foamed.

The installation of the assembly kit according to the invention can be placed in an existing espresso jug and is therefore unnecessary the purchase of another device, such as one equipment for frothing milk or a professional espresso machine. The assembly kit consequently represents an inexpensive Alternative to receiving a device which is suitable for making cappuccino.

An espresso pot that comes with a assembly kit according to the invention equipped is a further object of the invention.
