Abstract

A flushing station is provided. The flushing station includes a connection piece for a hot water pipe, a connection piece for a cold water pipe, a collecting tank with a siphon for draining the water, pipes at the connection pieces which conduct the water from the connection pieces into the collecting tank at least one sensor per pipe a control unit connected to the sensor, a valve actuatable in the pipes, wherein the control unit is coupled to the actuatable valve and the actuatable valve can be opened by the control unit for flushing the hot or cold water pipe. According to the invention, a flow restrictor and a flow straightener are integrated in each of the pipes.

First claim

The invention claimed is:

1. A flushing station comprising:
a connection piece for a hot water pipe;
a connection piece for a cold water pipe;
a collecting tank with a siphon for draining water;
pipes at the connection pieces which conduct the water from the connection pieces into the collecting tank;
at least one sensor per pipe;
a control unit connected to the sensors connected to the pipes; and
valves, each respective valve being actuatable in a respective pipe of the pipes;
wherein the control unit is coupled to each respective valve and the valves can be individually opened by the control unit for flushing one or more of the hot water pipe and the cold water pipe,
wherein a flow restrictor and a flow straightener are integrated in each of the pipes, and
wherein the flow restrictor limits the amount of water and the flow straightener creases a laminar flow.

2. The flushing station according to claim 1 , wherein the flow restrictor is designed for a water flow rate of 16 liters per minute and the flow straightener is designed for a water flow rate of 15 liters per minute.

3. The flushing station according to claim 1 , wherein the flow restrictor is arranged upstream of the flow straightener in a flow direction of the water through the pipes.

4. The flushing station according to claim 1 , wherein each respective valve is designed as a ball valve.

5. The flushing station according to claim 1 , wherein the flushing station further comprises a housing made of expanded polypropylene and only the connection pieces are guided through the housing.

6. The flushing station according to claim 1 , wherein the flushing station further comprises a splash guard arranged in the collecting tank, into which the pipes open.

7. The flushing station according to claim 6 , wherein the collecting tank is funnel-shaped towards the siphon and the splash guard is also funnel-shaped and is mounted in a funnel-shaped region at a distance from the collecting tank.

8. The flushing station according to claim 1 , wherein the flushing station further comprises an overflow sensor arranged in the collecting tank, which, when triggered, causes a closing of the valves and blocking of further flushing in the control unit.

9. The flushing station according to claim 1 , wherein the connection pieces are formed laterally opposite each other on the flushing station.

10. The flushing station according to claim 1 , wherein each of the pipes is L-shaped, such that an identically shaped pipe can be used to conduct the water from the connection pieces.

11. The flushing station according to claim 1 , wherein one pipe of the pipes has a hot water inlet and another pipe of the pipes has a cold water inlet, such that the hot water inlet and the cold water inlet are respectively configured to connect to a hot water connection and a cold water connection of a wash basin.

12. The flushing station according to claim 6 , wherein another connection piece is formed on a wastewater pipe, which also opens into the collecting tank and into the splash guard.

13. The flushing station according to claim 12 , wherein the flushing station further comprises a dirt trap in the wastewater pipe.

14. The flushing station according to claim 13 , wherein the dirt trap is produced by 3D printing.
