International ClassE03D009/10AbstractA toilet system which can be rinsed by a rinsing device. A pipe is connected to the toilet pan and leads to a sanitation pipe. Means are provided for transporting a suction material from the toilet pan into the pipe and into the sanitation pipe. Said means comprise two valves which are arranged in the pipe and a pressure chamber is disposed in-between. In order to suction the suction material from the toilet pan, low pressure is produced in the pressure chamber and used to transport said suctioned material. The pressure chamber is embodied as a piston cylinder and the piston is connected to a controllable drive in order to produce the high and low pressure. The inventive toilet system enables rinsing to occur using a very small amount of water and which can be adapted to different toilet pans. | |
