Description

The The invention relates to a vehicle, in particular a motor vehicle, with a tap module for liquids and / or Steam, in particular for hot water, according to the preamble of claim 1.

The use of hot water generation devices is already known in vehicles in connection with the production of infusion beverages, such as coffee. So it is for example from the DE 103 47 047 A1 known to arrange a water tank together with pump and heater in a trunk of a motor vehicle, so that from there heated water via a corresponding feed line to a brewing unit, which is arranged in the passenger compartment, can be supplied. In this brewing unit can be inserted coffee or tea tabs, which are then flowed through by the heated water to provide coffee or tea available, which is guided as an extract via another feed line to a cup holder on a cup positioned where dripped in the usual way from above into the cup. The cup holder is here part of a rest container, can be disposed of in the extra residues or other waste. Such a device is a total of relatively large construction and large volume and less practical for use in motor vehicles, especially for optical reasons. A similar hot beverage preparation device is also known from DE 10 2004 016 194 A1 known.

From the WO 00/71006 A1 Furthermore, a hot water conditioner is known, which can be connected for installation in a motor vehicle to a 12 or 24 V DC power source of the electrical system of the vehicle. For this purpose, a low-voltage boiler is provided, in which with one or two 12 V elements about 3.5 dl of water can be heated. This amount of hot water should be sufficient to be able to deliver one to two portions of hot water within a very short time in a vessel. The control of the amount of water via a pump and a valve. As a fresh water reservoir is a commercial PET bottle, on the standard spout opening a connection valve is screwed. As a reservoir for a coffee granules is a commercial coffee powder. The aroma closure of the can is broken during the insertion of the can on the connecting piece through the arranged in this neck opener. A cup or a cup, in which the coffee granules and / or the hot water is filled, is held by a bracket under a tap, so that here drips the hot water from above into the cup or in the cup.

Next is from the DE 102 34 025 A1 a device for processing hot drinks for a motor vehicle, in which a mobile container an espresso machine is housed, which is operable through an opening on top of the container. The container has the shape of a cuboid and is made of a stable plastic, wherein fixing means are arranged on the bottom side, which serve to hold the container in the passenger compartment, wherein the container can be moved in different positions along a rail arranged on the vehicle floor. Through an opening on the top of the container, the espresso machine can be positively inserted into the container. A similar construction in connection with a hot water heater is also from the DE 198 16 031 A1 known.

A device for hot water or steam generation for vehicles is also from the WO 2008/098683 A2 known. In this structure, a separate Wasserzapfstelle is provided in the vehicle, which can be operated independently of a coffee or espresso machine, for example, and thus is also available for other applications or applications. As containers which can be connected to the tapping point, a drinking vessel is described here in particular which, in the preferred embodiment, serves as a coffee cup which can be equipped with a portion capsule containing a coffee powder. In an alternative embodiment, the configuration of the container is described here as a hot-towel receptacle, in which a refreshment towel or a towel with hot water or steam of predetermined temperature is applied.
