Abstract (en)
This publication discloses a dry toilet system particularly suited for multi-storey buildings. The system has the toilet seats (4) of each apartment connected via a check valve (19) and a connection branch (5) to a vertical waste stack (1). The lower end of the waste stack (1) is connected via a control valve (8) to an automatically replaced collection container (10). The toilet and household wastes are removed via the toilet seat (4), whereby they are allowed to freely fall to the lower end of the waste stack (1), and therefrom further into the collection container (10) at the opening of the cyclicly operating control valve (8). The backflow of odours from the waste stack (1) via the toilet seat (4) to the toilet space is prevented with the help of a venting duct (6) and a roof fan (7). The suction by roof fan (7) produces a vacuum in the venting duct (6) and the waste stack (1), thereby venting the odours to the roof of the building. <IMAGE>
