Abstract

An outlet element for a drinking-water dispenser containing a first water route formed by the outlet element and opening on a first exit plane, water flowing through the first water route being dispensed via the outlet element, a second water route formed by the outlet element and opening on a second exit plane, water flowing through the second water route being dispensed via the outlet element, the second water route differing at least sectionally from the first water route, a third water route formed by the outlet element and opening on a third exit plane, water flowing through the third water route being dispensed via the outlet element, the third water route extending separately from the first water route and the second water route through the outlet element and the third exit plane having a distance of at least 1 mm from the first exit plane and the second exit plane.

First claim

The invention claimed is:

1 . A drinking water dispensing system ( 2 ) that selectively dispenses at least partially treated drinking water or tap water, the drinking water dispensing system ( 2 ) comprising:
a water faucet ( 13 ) having an outlet element ( 1 ) from which the at least partially treated drinking water or the tap water can be selectively dispensed, a drinking-water treatment device ( 14 ) operatively connected to a drinking-water channel ( 15 ) of the water faucet ( 13 ), the drinking-water treatment device ( 14 ) being configured to supply the at least partially treated drinking water, a mixing chamber ( 16 ) configured to adjust the temperature of the tap water, and a control device ( 17 ) configured to check whether the tap water is being dispensed by the drinking water dispensing system ( 2 ) and to allow dispensing of the at least partially treated drinking water only when no tap water is being dispensed by the drinking water dispensing system ( 2 ), wherein the outlet element ( 1 ) comprises: a first water route ( 3 ) that extends from the outlet element ( 1 ) to a first exit plane ( 4 ) from which the tap water flowing through the first water route ( 3 ) can be dispensed from the outlet element ( 1 ), a second water route ( 5 ) that extends from the outlet element ( 1 ) to a second exit plane ( 6 ) from which the tap water flowing through the second water route ( 5 ) can be dispensed via the outlet element ( 1 ),
wherein the first water route ( 3 ) and the second water route ( 5 ) are channels formed within the outlet element ( 1 ), and
a third water route ( 7 ) that extends from the outlet element ( 1 ) to a third exit plane ( 8 ) from which at least partially treated drinking water flowing through the third water route ( 7 ) can be dispensed via the outlet element ( 1 ),
wherein the third water route ( 7 ) is a channel formed within the outlet element ( 1 ) that is separated from the first water route ( 3 ) and the second water route ( 5 ),
wherein the third exit plane ( 8 ) extends from the outlet element ( 1 ) to a distance ( 9 ) that is at least 1 mm beyond the first exit plane ( 4 ) and the second exit plane ( 6 ), wherein the first water route ( 3 ) and the second water route ( 5 ) are operatively connected to the mixing chamber ( 16 ), and wherein the third water route ( 7 ) of the outlet element ( 1 ) is operatively connected to the drinking-water channel ( 15 ).

2 . The drinking water dispensing system ( 2 ) according to claim 1 , wherein the first water route ( 3 ), the second water route ( 5 ), and the third water route ( 7 ) exit from the outlet element ( 1 ) in a common direction.

3 . The drinking water dispensing system ( 2 ) according to claim 2 , wherein the common direction is a downward direction.

4 . The drinking water dispensing system ( 2 ) according to claim 2 , wherein the common direction is a forward direction.

5 . The drinking water dispensing system ( 2 ) according to claim 1 , wherein the distance ( 9 ) is at least 3 mm.

6 . The drinking water dispensing system ( 2 ) according to claim 1 , wherein the outlet element ( 1 ) further comprises a mechanical control element ( 10 ) for the manual selection of either the first water route ( 3 ) or the second water route ( 5 ).

7 . The drinking water dispensing system ( 2 ) according to claim 1 , wherein the outlet element ( 1 ) comprises an electronic control element ( 11 ) for the manual selection of the third water route ( 5 ).

8 . The drinking water dispensing system ( 2 ) according to claim 7 , wherein the electronic control element ( 11 ) comprises a non-contact sensor ( 12 ).

9 . The drinking water dispensing system ( 2 ) according to claim 1 , wherein the at least partially treated drinking water comprises filtered, cooled and/or carbonated drinking water.

10 . A method of dispensing at least partially treated drinking water, comprising the steps outlined below:
a) providing the drinking-water dispenser ( 2 ) according to claim 1 , b) recognizing a user request to dispense the at least partially treated drinking water, c) checking whether the drinking-water dispenser ( 2 ) is currently being used to dispense the tap water, and d) opening a flow of the at least partially treated drinking water through the third water route ( 7 ) only if the drinking-water dispenser ( 2 ) is currently not being used to dispense the tap water.

11 . The method of claim 10 , wherein a non-contact sensor ( 12 ) is used to detect the user request to dispense the at least partially treated drinking water.
