Device for making beverages

The invention relates to a device for producing beverages by adding a beverage concentrate to carbonated tap water.

Devices of the type described above are known. she are called postmix systems. In them is carbonated made impregnated water with a given carbonic acid content, which is used by adding beverage concentrate to produce a preferably non-alcoholic beverage.

In a known embodiment of such a device "-only manufactures] For beverages, a pressure vessel is provided to which the pressurized tap water is carbonated from a carbonic acid storage container is added and from which the impregnated water is fed to a mixing valve, in which it is added before the addition of the concentrate with still tap water to achieve the desired ir th carbonic acid content can be mixed.

In a known embodiment of the device described above is this through a water pressure regulator with regard to his Pressure-regulated tap water is sprayed in the upper part of the pressure vessel, which increases the surface area of the water, which favors its impregnation with carbonic acid. By supplying carbon dioxide from a carbon dioxide storage tank, the Depending on the water inlet temperature and the tap water pressure, a carbonated water with a certain carbonic acid

salary. Here it is necessary to check the filling level of the pressure vessel for example darch two built-in electrodes between one A maximum and a minimum value to regulate, these two electrodes control a solenoid valve. The impregnated water is removed from the lower part of the pressure vessel through a built-in riser pipe, and fed to the mixing switch. By supplying still, ' that is, normal tap water can reduce the carbonic acid content of the f Pressure vessel impregnated water can be reduced to the desired carbonic acid content for the respective drink. In the fresh water supply line there is preferably a water filter to filter the tap water coming from the city water connection. A water pressure regulator is also provided behind this water filter, which regulates the water pressure of both the pressure vessel and the the mixing valve regulates the water supplied.

Have the known devices of the type described above the disadvantage that they include technically complex components with the pressure vessel and possibly the mixing switch, which together are expensive with their accessories and also have a not inconsiderable space requirement.

The present invention is based on the object of a device of the type described above to create that with relatively few and simple components and can be accommodated in a space-saving manner.

The solution to this problem by the invention is thereby characterized in that in the tap water supply line a cylindrical Mixing tank is arranged in which the with a check valve and a supply line provided with a nozzle ends and in the one also Carbonic acid line provided with a check valve was introduced is * ;.

This inventive training, it is possible on the expensive To do without pressure vessel with level control for carbonating the water, so that not only a simplification of the device

but also achieved a considerable reduction in space requirements
can be. The cylindrical mixing container can have a circular or polygonal cross section. Since that from the
Tap water supply incoming tap water by means of the nozzle in
If the mixing tank is injected, the surface of the water increases, which results in a good impregnation. the
The degree of impregnation is essentially dependent on the pressure of the
supplied carbonic acid, so that it is possible to adjust the degree of impregnation
to vary by changing the carbonic acid pressure. Although the device according to the invention is intended in particular for the production of carbonated water with a certain carbonic acid content,
In this way, a variable degree of impregnation can also be achieved by changing the carbonic acid pressure.

To ensure an intimate mixing of the tap water with the supplied
Carbon dioxide and thus a uniform impregnation is to be achieved
According to a further feature of the invention, the mouth of the carbon dioxide line is directed towards the nozzle of the tap water supply line. f. This results in a certain turbulence in the mixing container, which s favors the mixing process. \

In a further development of the idea according to the invention, we will continue

proposed a cooling coil in front of and / or behind the mixing container
to arrange. It is therefore optionally possible to use a so-called warm | or cold carbonation. k

According to a further feature of the invention, a low-pressure pump with a pressure monitor is arranged in the tap water \ supply line. This further expansion of the device according to the invention is necessary when the pressure in the water network is subject to greater fluctuations, | which can no longer be controlled by a water pressure regulator built into the tap water supply line. According to the invention it may be advantageous, finally, except for the tap water supply line I: the Wasserdruekregler incorporate a water filter. {

In the drawing are two exemplary embodiments of the invention: ■ sen device shown schematically, namely show: |

Pig. 1 shows a first embodiment for cold carbonation and 2 shows a second embodiment for warm carbonation.

The training according to Fig.l, which represents the simplest embodiment shows a supply line 1 for tap water coming from a city water connection, in which a water filter 2 and a water pressure regulator 3 are built in. A cooling coil 4 is also arranged behind the water pressure regulator 3.

The supply line 1 for the tap water is behind the cooling coil 4 provided with a check valve 5 and ends in a cylindri- ^ see mixing container 6. At the end of the supply line 1, a nozzle 7 is arranged that splashes the tap water inside the mixing container 6 and thereby creates an enlargement of the surface.

The mixing container 6 is made of a carbonic acid bottle 8 under Zwischenei circuit of a pressure regulator 9 carbonic acid of a certain pressure fed through a carbonic acid line 10. Even at the end of this Kohler Acid line 10, a check valve 11 is arranged, which prevents that a backflow occurs in the carbon dioxide line 10. The mouth of the carbon dioxide line Iu is on the nozzle 7 of the supply line 1 directed, so that a turbulence is generated in the mixing container 6, the ensures a good mix of carbon dioxide and the splashed tap water.

The water impregnated in this way in the mixing container 6 is fed through a line 12 to a tap 13, which is also supplied with a beverage concentrate through a syrup line 14, so that a drink can be dispensed from the tap 13 in the so-called postmix process can. Which takes place in the device according Pig.l Karbonierungsvorgang is referred to as Kaltkarbonierung as dei mixing vessel 6 is arranged in the direction of flow of the tap water behind the cooling coil. 4

In the embodiment according to Pig.2, that in all essential individual parts corresponds to the first embodiment is the cooling coil

in the line running between the mixing container 6 and the tap 13 12 arranged. In this embodiment there is thus a warm carbonation instead, as the impregnated water only occurs after the impregnation process is cooled.

In this second embodiment, a low-pressure pump with a pressure switch 16 is arranged in the feed line 1 for the soffit water leading to the mixing container 6, which ensures that even larger pressure fluctuations in the city water connection are compensated, so that a uniform impregnation takes place in the mixing container 6 despite considerable pressure differences.
