A liquid waste disposal and canister flushing system includes a cabinet (6) with a sink (14k) for receiving the canister (4) and a subsink (141) for receiving a lower portion thereof. The subsink (141) is connected to a drain line (140). A plunger subassembly (12) includes a plunger rod (92) and a stopper (95) which functions as a drain valve for the canister (4). An injection jet (34) is connected to water and cleaning sources (21, 39) and discharges diluted cleaning solution into the canister (4) for flushing same. The injection jet (34) engages the plunger subassembly (12) for ejecting the stopper (95) from a canister opening (12a). A control system (10) includes a programmable microprocessor (50) which can be programmed to provide drain and flush cycles of predetermined duration. A method of liquid waste disposal and canister flushing is also provided.

L'invention concerne une évacuation de déchets liquides et un système de rinçage de récipient comprenant un caisson (6) pourvu d'un évier (14k) destiné à recevoir le récipient (4) et un sous-évier (141) destiné à recevoir une partie inférieure de ce dernier. Le sous-évier (141) est relié à un tuyau d'évacuation (140). Un sous-ensemble (12) piston plongeur comporte une tige support (92) de piston et un bouchon (95) qui sert de robinet de purge du récipient (4). Un système d'injection (34) à pression est relié aux sources d'eau et de nettoyage (21, 39) et décharge dans le récipient (4) une solution de nettoyage, diluée pour le rincer. Le jet d'injection (34) vient en contact avec le sous-ensemble (12) piston plongeur pour éjecter le bouchon (95) d'une ouverture (12a) du récipient. Un système (10) de commande comprend un microprocesseur (50) programmable susceptible d'être programmé afin d'assurer des cycles d'évacuation et de rinçage de durée prédéterminée. L'invention porte également sur un procédé permettant l'évacuation de déchets liquides et le rinçage du récipient.
