Abstract

L'invention concerne un système de toilettes sèches comprenant une unité de toilette (12) qui possède une ouverture à excréments (22) se trouvant dans une base de toilette (14) et à travers laquelle les excréments excrétés par l'utilisateur chutent dans un récipient collecteur (23) disposé au-dessous de l'ouverture à excréments (22) et se trouvant dans une position de collecte (27). Il existe ici plusieurs récipients collecteurs (23) qui peuvent être déplacés en alternance entre la position de collecte (27) et au moins une position de séchage (28), dans laquelle les excréments sèchent en diminuant de volume. La position de séchage (28) se trouve dans une unité de séchage (41) du système de toilettes sèches (11). Selon l'invention, il existe un dispositif de transport (26) servant à transporter le récipient collecteur (23) entre la position de collecte (27) et la position de séchage (28) et un système d'actionnement (39) pouvant être activé par l'utilisateur pour actionner le dispositif de transport (26) de telle sorte que le récipient collecteur (23) chargé avec les excréments de l'utilisateur puisse être éloigné de la position de collecte (27) et remplacé par un autre récipient collecteur (23).
