9. The plumbing fixture (1) according to claim 8, wherein a second non-return valve (16), which prevents a backflow of liquid or compressed air (11) from the supply line (3) into the second water line (15), is arranged between the third connection (14) and the second water line (15).

10. The plumbing fixture (1) according to any one of the preceding claims, wherein the shower system (2) has a collecting device (17) for the liquid that has exited the outlet (4), wherein the supply line (3) is fluidically connected to the collecting device (17) so that the liquid can be used as a circulating liquid.

Description

[0030] The invention and the technical environment are explained in more detail below with reference to the FIGURE. It should be noted that the FIGURE shows a particularly preferred embodiment variant of the invention, but is not limited thereto.

[0031] FIG. 1 shows an exemplary and schematic plumbing fixture.

[0032] The plumbing fixture 1 is provided for a shower system 2. The plumbing fixture 1 comprises components that can be installed in a shower system 2. The described plumbing fixture 1 is connected to the known components, such as the control unit or actuating unit (not shown), shower head 18, and drain 19. The liquid can exit the supply line 3 via the outlet 4. The liquid that has exited the supply line 3 can be used by a user for showering. The shower system 2 has a collecting device 17 for the liquid exiting the outlet 4, wherein the supply line 3 is fluidically connected to the collecting device 17 via the drain 19, so that the liquid can be used as a circulating liquid.

[0033] The plumbing fixture 1 comprises a supply line 3 for supplying at least one liquid (e.g. water, or fresh water or circulating water) towards an outlet 4 of the plumbing fixture 1 and a first connection 5 to the supply line 3 for switchably connecting the supply line 3 to a compressed-air line 6. A liquid present in the supply line 3 can be purged through the outlet 4 via the compressed-air line 6. A filter 20 is arranged in the compressed-air line 6.

[0034] The plumbing fixture 1 comprises a second connection 7 to the supply line 3 for switchably connecting the supply line 3 to a first water line 8. The first water line 8 can be used to flush the supply line 3 with fresh water.

[0035] A first non-return valve 9, which prevents a backflow of water 10 or compressed air 11 from the supply line 3 into the first water line 8, is arranged between the second connection 7 and the first water line 8.

[0036] The first connection 5 and the second connection 7 each comprise a switchable valve 12. Switching the valve 12 can be done manually or automatically, e.g. triggered by use of the shower system 2. The supply line 3 can be connected to the compressed-air line 6 or to the first water line 8 via the respective valve 12. Each valve 12 has two inputs and one output. The inputs are connected to the inflow of the supply line 3 and the first water line 8 or the compressed-air line 6. The output is connected to the outflow of the supply line 3 towards the outlet 4. Each of the inlets can be switchably connected to the output via the respective valve 12.

[0037] The plumbing fixture 1 comprises a pump 13 for supplying the liquid, or for supplying the compressed air, or for supplying a mixture of liquid and compressed air through the supply line 3. The pump 13 is arranged between the outlet 4 and the connections 5, 7. The inlet of the pump 13 is thus connected to the connections 5, 7, and the outlet of the pump 13 is connected to the outlet 4.

[0038] The plumbing fixture 1 comprises a third connection 14 to the supply line 3 for connecting the supply line 3 to a second water line 15. A second non-return valve 16, which prevents a backflow of water 10 or compressed air 11 from the supply line 3 into the second water line 15, is arranged between the third connection 14 and the second water line 15. Mixed water (i.e. a mixture of cold water and hot water) from a known mixer tap can be supplied to the supply line 3 via the second water line.
