Abstract:
Water jet ventilator for ventilating water flowing through the water jet ventilator and for forming an aerated water jet comprising a mixture of water and air, the water jet ventilator being adapted for connecting the water jet ventilator to a water outlet end of a sanitary fitting, the water jet ventilator comprising:a water inlet for receiving water flowing from the sanitary fitting into the water jet ventilator; a water outlet for discharging water out of the water jet ventilator and; ventilation devices disposed between the water inlet and the water outlet for splitting up and mixing the inflowing water with drawn in air; the ventilation devices comprising a plurality of components coming into contact with water flowing from the water inlet to the water outlet; wherein at least one of said components comprises a surface for contacting the water, the at least one of said components having a deformably soft portion at least in a vicinity of the water outlet, structured such that deforming the deformably soft portion can detach hard residues deposited on the deformably soft portion and the residues can be flushed away by a subsequent flow of water through the water jet ventilator; wherein the plurality of components comprise components having areas located at the water outlet and wherein the areas include a deformable coating forming at least part of the deformably soft portion.
