Abstract

An air suction device for a toilet drainage channel, capable of good and silent toilet flushing. The air suction device (200) for the toilet drainage channel (5) has air suction means for sucking air from the toilet drainage channel (5) connected to the downstream side of a water sealing part (4) of a toilet body (1). The air suction means has an ejector (30) serving as a negative pressure generator and also has a suction tank (80) connected between the ejector (30) and the toilet drainage channel (5). The air suction device (200) further has a control device (C) for controlling both execution of a suction stroke in which the suction tank (80) sucks air from the toilet drainage channel (5) and execution of an air exhaust stroke in which the suction tank (80) exhausts air into the toilet drainage channel (5). The control device (C) executes the air suction stroke after the start of the supply of flush water to the bowl (2) of the toilet body (1) and then executes the air exhaust stroke before the completion of the supply of the flush water to the bowl (2).
