Rail vehicle having a sanitary assembly

Abstract

A rail vehicle has a sanitary assembly at which waste water is produced. A waste water pipeline extends between the sanitary assembly and a connector for a target container for receiving waste water. The waste water connector of the sanitary assembly is located lower than at least a portion of the waste water pipeline to the target container so that the waste water has to be conveyed through the waste water line counter to the force of gravity. The waste water pipeline is formed with at least one return flow barrier.

1 . A rail vehicle with a sanitary assembly at which waste water is produced, the rail vehicle comprising:
 a waste water pipeline extending between the sanitary assembly and a connector for a target container for receiving waste water;   wherein a waste water connector for connecting said waste water pipeline to the sanitary assembly is disposed lower than at least a portion of said waste water pipeline leading to the target container, and the waste water is conveyed through the waste water line counter to a force of gravity; and   at least one return flow barrier disposed in said waste water pipeline and arranged between said waste water connector of the sanitary assembly and said connector for the target container.   
     
     
         2 . The rail vehicle according to  claim 1 , wherein said return flow barrier is disposed in a substantially horizontally extending portion of said waste water pipeline. 
     
     
         3 . The rail vehicle according to  claim 1 , wherein said return flow barrier is formed by a rise and a subsequent drop in a course of said waste water pipeline. 
     
     
         4 . The rail vehicle according to  claim 3 , wherein said rise amounts to at least one pipe diameter. 
     
     
         5 . The rail vehicle according to  claim 1 , wherein said return flow barrier is formed by pipe bends. 
     
     
         6 . The rail vehicle according to  claim 1 , wherein a portion of said waste water pipeline that is located downstream of said return flow barrier in a conveying direction of the waste water is a heatable portion. 
     
     
         7 . The rail vehicle according to  claim 6 , which comprises a heater disposed in a vicinity or at said heatable portion of said waste water pipeline.
