Abstract
A device for dispensing an aerated jet of water comprises an outer casing (10), a dispenser plate (14) which closes said outer casing and in which a plurality of nozzles (16) for the outlet of the water is provided, and an intermediate plate (18) positioned in said casing so as to define a water inlet chamber (20) communicating with a water supply duct (21), and a water outlet chamber (24) communicating with the outlet nozzles (16) of the water. In the intermediate plate (18) there is provided an air-water mixing chamber (26) communicating with the water inlet chamber through a plurality of water inlet holes (28), with the outside environment through a number of air intake holes (30) and with the water outlet chamber through a plurality of aerated water (32) outlet holes.
Claims16
Device for dispensing an aerated jet of water, comprising:
- an outer casing (10),
- a dispenser plate (14) which closes said outer casing and in which a plurality of nozzles (16) for the outlet of the water is provided,
- an intermediate plate (18) positioned in said casing so as to define a water inlet chamber (20) communicating with a water supply duct (21), and a water outlet chamber (24) communicating with the outlet nozzles (16) of the water,
- characterised by the fact that in said intermediate plate (18) there is provided an air-water mixing chamber (26) communicating with the water inlet chamber through a plurality of water inlet holes (28), with the outside environment through a number of air intake holes (30) and with the water outlet chamber through a plurality of aerated water (32) outlet holes.
Device according to any of the previous claims, wherein the inlet holes of the water (28) into the mixing chamber (26) are made along at least one circumference concentric to the water inlet chamber and having a radius essentially included between one-third and two-thirds of the radius of said chamber.
Device according to any of the previous claims, wherein the air-water mixing chamber (26) has an annular extension.
Device according to any of the previous claims, wherein the water inlet holes (28) are aligned with the outlet holes of the aerated water (32).
Device according to any of the previous claims, wherein the air intake holes (30) go through the dispenser plate.
Device according to any of the previous claims, wherein the air intake holes (30) are made in respective air intake pipes (31) which extend from the intermediate plate and which are inserted in respective holes (33) made in the dispenser plate (14).
Device according to any of the previous claims, wherein the outer casing, the water inlet chamber and the water outlet chamber are of a flat shape, extending mainly in a direction orthogonal to that of the outgoing jet of water.
Device according to any of the previous claims, wherein the dispenser plate (14) forms a hermetic seal with the rim of the outer casing (10) to which it is attached.
Device according to the previous claim, wherein the dispenser plate (14) comprises a perforated outer plate (14a) which closes the outer casing forming a seal along the peripheral rim, and an inner plate (14b) laid over the outer plate, having a number of dispensing nozzles and in turn perforated for the passage of the air intake pipes (31).
Device according to any of the previous claims, wherein the intermediate plate (18) and the dispenser plate (14) are fitted with complementary alignment devices (19, 19′) able to prevent their rotation in relation to one another.
