Description
BRIEF DESCRIPTION OF THE FIGURES
(1) Exemplary embodiments of the present invention will be explained in greater detail below with reference to figures. These serve solely for explanation purposes and are not to be interpreted as limiting. In the figures:
(2) FIG. 1 shows a schematic perspective view of a water outlet according to the invention;
(3) FIG. 2 shows a side view of the water outlet of FIG. 1, without the housing of the mixing unit; and
(4) FIG. 3 shows a sectional side view of the water outlet of FIG. 1 through the longitudinal axis.
DETAILED DESCRIPTION OF THE INVENTION
(5) FIG. 1 shows a schematic perspective view of a water outlet according to the invention. The water outlet comprises a connection unit 4 with two connections 41, for example for hot and cold water. The connection unit 4 additionally comprises a mixing unit 42, in which hot and cold water can be mixed with one another. A bezel 44 is provided on the side of the connection unit 4 that is directed towards a user in the use position, said bezel surrounding an outer pipe 2. The bezel 44 is integrated in a display 43 and is recessed into the latter so as to be substantially flush therewith. An operating element 210 is arranged at the outlet end of the outlet pipe 2, which operating element is rotatable about a pipe longitudinal axis L. The operating element 210 can for example be pressed once in order to turn on the water. The outflow amount can be changed by pressing repeatedly or by pressing for a longer duration. The water temperature can be changed by rotating the operating element 210 in the clockwise direction or in the counterclockwise direction.
(6) FIG. 2 shows a side view of the water outlet of FIG. 1, without the housing of the mixing unit 42. A fixing means 3 in the form of a screw is provided on the outer pipe 2. The screw 3 can be turned in a threaded bore provided for this purpose in the outer pipe 2. If the screw 3 is loosened, the outer pipe 2 can be displaced on the inner pipe 1 along the longitudinal axis L such that the screw 3 comes to lie between the connection plate 40 and the bezel 44.
(7) FIG. 3 shows a sectional side view of the water outlet of FIG. 1 through the longitudinal axis L of the outflow pipe. In the intended use position, the inner pipe 1 is arranged on a side of the connection plate 40 of the connection unit 4 that is directed towards a user. In the embodiment shown, the inner pipe 1 is screwed onto a threaded sleeve that is arranged on the connection plate 40. At its connection end 10, the inner pipe 1 comprises a thickened area and an end flange. A threaded bore extends through the flange and the thickened area in the region of the connection end 10. The inner pipe 1 comprises a plurality of circumferential grooves 12 which are arranged next to the thickened area in a manner spaced apart from one another along the longitudinal axis L on the circumference of the inner pipe. In the assembled state, the circumferential grooves are evenly distributed in a region next to the thickened area and as far as the bezel 44. Two sealing grooves are provided at an outflow end 11 of the inner pipe 1 which is opposite the connection end 10, said sealing grooves being spaced apart from one another and having a seal 13 provided in each case therein. The seals shown are O-rings. However, other commercially available round seals can also be used. The outer pipe 2 comprises a conduit pipe 22 which is displaceable along the longitudinal axis L with its inner diameter on the outer diameter of the inner pipe 1. The inner diameter is defined by a bore which extends from a connection end of the outer pipe 2 towards an outlet end 21. The conduit pipe 22 is closed in the outermost region of the outlet end 21. A lateral opening is provided in the conduit pipe 22, through which the water can flow out of the outer pipe. The conduit pipe 22 is partially surrounded by a casing pipe 23. The conduit pipe 22 has, on the connection side thereof, a circumferential collar against which the casing pipe 23 bears. The casing pipe extends beyond the closed end of the conduit pipe 222. The operating element 210 is recessed into the part of the casing pipe 23 that projects beyond the conduit pipe 22. The operating element 210 comprises a push button and a rotary knob. The lateral opening in the conduit pipe 22 is surrounded by a collar of the casing pipe 23. A threaded bore is provided in the lateral opening, into which a jet regulator 211 can be screwed. A mixing unit 42 having a closed housing is arranged on the side of the connection plate 40 that is directed towards the user. The bezel 44 is arranged on the side of the housing of the mixing unit 42 that faces towards the user. Hot water and cold water can pass from the respective connection 41 through a respective conduit to the mixing unit 42, and from there via a common conduit via the connection plate 40 into the inner pipe 1 and from the inner pipe 1 via the outer pipe 2 and the jet regulator 211 into a region below the outlet end 21 of the outer pipe 2.
