(2) FIG. 1 shows a schematic representation of an embodiment of a subject water dispenser intermediate part; and

(3) FIG. 2 shows a schematic representation of an arrangement of water reservoir with drinking vessel, water dispenser intermediate part and water tank.

DETAILED DESCRIPTION

(4) The FIG. 1 shows a schematic representation of a water dispenser intermediate part 1, wherein the water dispenser intermediate part 1 comprises first connecting means 2 for connecting a water tank 3 to the water dispenser intermediate part 1, wherein the water dispenser intermediate part 1 comprises second connecting means 4 for connecting the water dispenser intermediate part 1 to a water dispenser 5, wherein the water dispenser intermediate part 1 comprises a water pipe piece 6, which connects the first connecting means 2 to the second connecting means 4, wherein the water dispenser intermediate part 1 has a water consumption meter 7 and/or a water level sensor 15 for determining a water consumption via the water pipe piece 6 and/or a water level in the water tank 3, wherein the water dispenser intermediate part 1 has at least one transmitter part 8, 9 for wireless transmission of water consumption values and/or water level messages of the water tank 3.

(5) This allows existing water dispenser devices 5 to be retrofitted in such a way that they can at least send reports to a service company or another interested party regarding the quantity of water dispensed or the water level in the water tank 3 of the water dispenser. This can prevent a situation in which a water dispenser is unrecognizably out of water for delivery by sending a message to an employee or company responsible for exchanging the water tank 3, at the latest when a predefinable residual quantity in the water tank 3 has been reached.

(6) This also allows further information concerning the operation or operating status of the water dispenser 5, such as the operation according to an intended function, or the water temperature, to be transmitted. This makes it possible to retrofit already existing and still reliable devices easily and with little effort. As it is not necessary to transport the water dispenser 5 itself, as the water dispenser intermediate part 1 can simply be attached on site to a water dispenser 5 that has already been installed, the environment is also protected. If the water dispenser intermediate part 1 is defective, it can be replaced easily, quickly and without complications. Even in the event of a total failure of the water dispenser intermediate part 1, it is still possible to withdraw water. A combination of water dispenser 5 and water dispenser intermediate part 1 can easily be adapted to changing technical conditions, such as a changed telecommunications environment, by simply replacing an existing water dispenser intermediate part 1 with a new water dispenser intermediate part 1 adapted to the current state of transmission technology, without having to modify the water dispenser 5 itself. This makes it possible to operate a water dispenser 5 over its entire service life without restriction, wherein additional functions can be kept up to date by adapting or replacing the water dispenser intermediate part 1.

(7) The water dispenser intermediate part 1 in question is intended to be arranged between a water tank 3 or water reservoir, which is designed as a transparent plastic container with a capacity of for example 3 to 15 liters, and a water dispenser 5, which is also called water dispenser device 5 synonymously in this case. FIG. 2 shows a schematic representation of such an arrangement. In addition to the water dispenser 5, the water tank 3 and the water dispenser intermediate part 1, a drinking vessel 13 is also shown, which is arranged in a water withdrawal opening of the water dispenser 5.

(8) The water dispenser intermediate part 1 has first connecting means 2 for connecting a water tank 3 to the water dispenser intermediate part 1. The first connecting means 2 are designed to be essentially watertight, and preferably correspondingly diametrically opposed to the connecting means of a water tank 3 to be arranged. The first connecting means 2 are designed to approximately comprise a screw thread and at least one sealing ring.

(9) The water dispenser intermediate part 1 also has second connecting means 4 for connecting the water dispenser intermediate part 1 to a water dispenser device 5. The second connecting means 4 are also preferably designed to be watertight and correspondingly diametrically opposed to the connecting means of a water dispenser 5. The second connecting means 4 are designed to approximately comprise a screw thread and at least one sealing ring. It is preferably provided that the first connecting means 2 and the second connecting means 4 are designed in such a way that a release resistance of the first connecting means 2 is lower than a release resistance of the second connecting means 4. This can be achieved so that the connection between the water dispenser intermediate part 1 and the water dispenser 5 is not opened when the water tank 3 is replaced. Release resistance is designated as the resistance to the initial release of the corresponding fixed connection. With the preferred design of the two connecting means 2, 4 including screw threads, this would mean that the maximum required torque at the second connecting means 4 would be greater than the corresponding torque at the first connecting means 2.

(10) It is particularly preferably provided that a mechanical locking device is associated with the second connecting means 4, which mechanical locking device requires a tool, in particular a special or not commonly available tool, for separating the connection between the second connecting means 4 and the water dispenser 5.
