Abstract

The invention relates to a spray device having a fluid outlet structure that forms a spray jet, said fluid outlet structure having a plurality of jet outlet units of which at least two are configured as multi-duct jet outlet units having in each case at least one first outlet duct and at least one second outlet duct fluidically separated from the first. Moreover, the spray device has a fluid guide which is designed to conduct a fluid supplied to the spray device selectively to the first outlet ducts or to the second outlet ducts. According to the invention, a minimum spacing (A 12 ) between the outlet ducts of each particular multi-duct jet outlet unit ( 2 ) is smaller than a minimum spacing between the outlet ducts of in each case two multi-duct jet outlet units, and/or in at least one multi-duct jet outlet unit, a second outlet duct or a group of a plurality of second outlet ducts is arranged so as to surround a first outlet duct at least around a part of its circumference.

First claim

1 . A spray device, comprising:
a fluid outlet structure that forms a spray jet, said fluid outlet structure comprising a plurality of jet outlet units of which at least two are configured as multi-duct jet outlet units having in each case at least one first outlet duct and at least one second outlet duct fluidically separated from the first outlet duct, and a fluid guide which is designed to conduct a fluid supplied to the spray device selectively to the first outlet ducts or to the second outlet ducts, wherein a minimum spacing between the outlet ducts of each particular multi-duct jet outlet unit is smaller than a minimum spacing between the outlet ducts of in each case two multi-duct jet outlet units, or in at least one multi-duct jet outlet unit a second outlet duct or a group of a plurality of second outlet ducts is arranged so as to surround a first outlet duct at least around a part of a circumference of the first outlet duct.

2 . The spray device as claimed in claim 1 , wherein
a maximum spacing between the outlet ducts of each particular multi-duct jet outlet unit is smaller than a minimum spacing between the outlet ducts of in each case two different multi-duct jet outlet units, or an orifice of the at least one second outlet duct is at the same level as an orifice of the at least one first outlet duct with respect to a jet outlet direction or has a predetermined offset relative thereto.

3 . The spray device as claimed in claim 1 , wherein in at least one multi-duct jet outlet unit, a second outlet duct annularly surrounds a first outlet duct, or a group of a plurality of second outlet ducts surround a first outlet duct at a regular spacing from one another along a closed curve.

4 . The spray device as claimed in claim 1 , wherein the fluid outlet structure contains a jet disk which has an associated jet disk opening for each jet outlet unit.

5 . The spray device as claimed in claim 4 , wherein each particular jet outlet unit is formed by a jet outlet element extending through the associated jet disk opening.

6 . The spray device as claimed in claim 5 , wherein the fluid outlet structure contains a jet-form ing structure arranged on an inner side of the jet disk, the jet outlet elements, which comprise an elastic material, being arranged on said jet-forming structure.

7 . The spray device as claimed in claim 5 , wherein the jet outlet elements extend on the outlet side beyond an outer side of the jet disk with a projecting length of at least a quarter of an opening width of the jet disk openings.

8 . The spray device as claimed in claim 1 , wherein the fluid outlet structure comprises at least one first outlet chamber, out of which the first outlet ducts lead, and at least one second outlet chamber, fluidically separated from the first, out of which the second outlet ducts lead, wherein the first and the second outlet chambers are arranged alongside one another or in succession with regard to a jet outlet direction.

9 . The spray device as claimed in claim 1 , wherein at least one of the multi-duct jet outlet units has at least one third outlet duct fluidically separated from the at least one first and the at least one second outlet duct.

10 . The spray device as claimed in claim 9 , wherein the jet outlet unit with the at least one third outlet duct has in each case one first, second and third outlet duct, these being arranged alongside one another in a linear or triangular configuration.

11 . The spray device as claimed in claim 1 , wherein the spray device is configured as a sanitary shower spray device.
