METHOD OF MANUFACTURING A FAUCET BODY FOR A SANITARY FAUCET AND A FAUCET BODY FOR A SANITARY FAUCET

Abstract

A method for manufacturing a faucet body (1) for a sanitary faucet, having at least the following steps: a) production of the faucet body (1) in an injection mold, wherein the injection mold at least partially forms a brushed texture (3) on a surface (2) of the faucet body (1); b) coating the faucet body (1) with at least one first layer (4) comprising copper; and c) coating the faucet body (2) with at least one second layer (5) comprising a nickel-phosphorus alloy. A faucet body of plastic for a sanitary faucet is also proposed.

Claims

6. The method according to claim 3, wherein the grooves (7, 8) are each formed having a maximum average width (11) of 1 mm.

7. The method according to claim 3, wherein adjacent grooves (7, 8) of the plurality of grooves (7, 8) are formed having a maximum average spacing (12) of 1 mm.

8. The method according to claim 3, wherein the brushed texture (3) is formed having an average of 10 to 1,000 grooves (7, 8) per cm.sup.2.

9. The method according to claim 1, wherein the brushed texture (3) is at least partially formed as a pattern.

10. A faucet body (1) made of plastics for a sanitary faucet (13), comprising at least: a surface (2) that at least partially has a brushed structure (3); at least one first layer (4) comprising copper; and at least one second layer (5) comprising a nickel-phosphorus alloy.

Description

[0030] The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show a particularly preferred embodiment variant of the invention, but the invention is not limited thereto. The same reference numerals are used for the same components in the figures. In an exemplary and schematic manner,

[0031] FIG. 1 shows a side view of a sanitary faucet having a faucet body;

[0032] FIG. 2 shows a perspective view of the faucet body;

[0033] FIG. 3 shows an enlarged view of a section of the faucet body; and

[0034] FIG. 4 shows a sectional view of the faucet body.

[0035] FIG. 1 shows a side view of the sanitary faucet 13. The sanitary faucet 13 has a faucet body 1 having an outlet 15 with an outlet opening 14. The faucet body 1 is attached to a support 16, which in this case may be a wash basin. A mixing cartridge 17 is arranged in the faucet body 1, to which mixing cartridge cold water and hot water can be routed separately via supply lines 18. The mixing cartridge 17 is used to mix the cold water and the hot water to form a mixed water having a desired mixed-water temperature. The mixing cartridge 17 is connected to the outlet opening 14 in a fluid conveying manner, for the mixed water to be discharged via the outlet opening 14. A lever 19 can be used to actuate the mixing cartridge 17, which lever can be used to adjust the mixed-water temperature and a discharge quantity of the mixed water via the outlet opening 14.

[0036] FIG. 2 shows a perspective view of the faucet body 1 of the sanitary faucet 13 of FIG. 1. During the manufacture of the faucet body 1, the faucet body 1 was produced from plastic in a step a) in an injection mold of an injection molding machine not shown here. A brushed texture 3, shown enlarged in FIG. 2, was formed on an outer surface 2 of the faucet body 1 by the injection mold.

[0037] FIG. 3 shows an enlarged view of step a) of a section 21 of the faucet body 1, marked by a first rectangle 20 in FIG. 2. FIG. 3 shows a first groove 7 and a second groove 8 of a plurality of grooves 7, 8 of the brushed texture 3 shown in FIG. 2, which grooves extend in a brushing direction 22 shown in FIG. 2. The grooves 7, 8 have a length 9 in the brushing direction 22, a width 11 orthogonal to the length 9 and a depth 10 perpendicular to the surface 2 of the faucet body 1. The first groove 7 and the second groove 8 have a distance 12 from each other.

[0038] FIG. 4 shows a cross-section of an area of the faucet body 1 marked with a second rectangle 23 in FIG. 3, after the surface 2 of the faucet body 1 has been coated with a first layer 4 of copper in step b) and with a second layer 5 of a nickel-phosphorus alloy in step c). The first layer 4 was produced having a first layer thickness 24 and the second layer 5 having a second layer thickness 25, such that the first layer 4 and the second layer 5 have a total layer thickness 6.

[0039] This invention renders the manufacture of the faucet body 1 in a shorter manufacturing period and at lower manufacturing costs possible.
