"Espresso machine ¹¹ .

The innovation relates to an espresso machine with a steam container, a heating element for Heating water in the steam tank, a filter device, a water pipe for transporting under steam pressure of hot water from the steam container the filter device and with a stalked steam pipe for transporting steam.

Such espresso machines are generally known. A disadvantage of these devices is that there is foaming milk can only be made using the steam from the steam pipe if espresso coffee is being prepared at the same time will. It is not possible to generate steam without preparing coffee because the ground coffee in the filter device, that is effective as a counter pressure is missing.

The innovation now has the task of creating an espresso

To create a device that has at least one separate steam generation option for frothing milk. The “espresso machine” according to the innovation points to this the mark on that for the steam pipe and the water pipe a common tap is provided.

An exemplary embodiment according to the innovation Espresso machine has the indicator that in a first position of the tap the water pipe is open and the Steam pipe locked and in the second position of the tap the water pipe blocked and there; Steam pipe is open.

Another embodiment of the innovation Espresso machine shows that the tap has a third position in which the water pipe and the steam pipe is partially open. In this position It is still possible to have espresso coffee at the same time to prepare and froth milk.

In an alternative embodiment of the espresso machine the cock has a third position in which

the water pipe and the steam pipe are blocked and that
Heating element is switched off at the same time *

A special embodiment of the espresso machine indicates that the cock has a

has a cylindrical body running across the water pipe
and the steam pipe protrudes, which is cylindrical
Body is provided with two holes that are perpendicular
cross and those in the first or second position of the
Halmes in alignment with the water pipe or steam pipe

are adjustable.

Preferably the tap is with a cam disc
to operate an on / off switch, which can be found in
an electrical circuit of the heating element was added
is.

An embodiment of the innovation is in

shown in the drawing and is explained in more detail below

opens outside the housing. In an arm 16, the water pipe k and the steam pipe 5 extend parallel to one another. In this arm 16 there is a tap housing 17t which is provided with parallel connecting tubes 18 and 19 which are in the extension of the water pipe k and the steam pipe 5. The tap housing 17 is provided with a cylindrical bore 20. The tub 20 is formed by a cylindrical body 22 and an operating button 23- The cylinder-shaped body 22 fits into a bore 20 of the tap housing. The cylindrical body 22 is provided with two bores Zk and 25 which intersect perpendicularly. By turning the tap with the aid of the button 23, the bores Zk and 25 can be adjusted to be aligned with the connecting pipes 18 and 19, respectively, and in this way the water pipe k and the steam pipe 5 can be opened. Intermediate positions in which each of the tubes is only partially open are also possible. The tap is also provided with a cam disk 26 which actuates an on / off switch for the heating element 7.

In the figures 3a, b and c three different positions for the cock 21 and the cam disk 26 are shown in a schematic manner. In FIG. 3a, the steam pipe 5 is open and the water pipe k is closed. In this position it is possible to only generate steam. The .Switch 27 for the heating element is closed. In Fig. 3b the steam pipe 5 is blocked and the water pipe k open. The switch 27 is closed. In Fig. 3c the water pipe and the steam pipe are blocked. The switch 27 is open and the heating element 7 cannot be switched on. For the valve according to FIGS. 3a, b and c, the cam disk 26 is provided with two cams 28 and 29 which are displaced 90 opposite one another on the circumference of the disk.

In Fig. 3d an alternative representation for the locked position from Fig. 3c is shown. The diameters of the bores Zk and 25 have been chosen here in such a way that the water pipe and the steam pipe are somewhat open. In this position you can simultaneously

Espresso coffee is prepared and steam generated to froth milk. The switch 27 for the heating element 7 is closed. In this example, the cam disk 2.6 has only one cam 30. In addition to this double open position, a completely locked or open position and vice versa of the water pipe or the steam pipe, as in FIGS. 3a and 3b, are of course also possible.
