Abstract

The invention relates to a flushing system (10) comprising a tank (110), a water supply means and a siphon (120), the siphon comprising a descending pipe that opens into a toilet bowl and an ascending pipe that comprises at least one opening connecting the tank to the descending pipe, such that, after the flushing system has been actuated, the water contained in the ascending pipe flows back towards the tank, wherein: • - the tank comprises, at its base, a narrow portion forming a water collection cavity configured to collect at least some of the water flowing back from the ascending pipe to the tank after the flushing system has been actuated; and • - the water supply means comprises a pipe provided with an end (131) that opens into the collection cavity and is positioned so as to be submerged by the water flowing back into the tank after the flushing system has been actuated. According to the invention, the flushing system comprises a means (250) for unpriming the siphon (300), and the flow of air through the duct (252) of the unpriming means (250) is controlled by a solenoid valve (254).

Abstract

The invention relates to a flush siphon (300) comprising an inner cylinder (340) placed inside an outer cylinder (330), and: • - comprising a connector (350) providing a connection between the outer cylinder (330) and the inner cylinder (340); wherein the outer cylinder (330), the inner cylinder (340), and a portion of the connector (350) thereby define an ascending water pipe (310), and such that the inner cylinder (340) and a portion of the connector (350) thereby define a descending water pipe (320); • - wherein the outer cylinder (330) comprises a lower end connected to a tank (110) and an upper end connected to the connector (350); • - wherein the inner cylinder (340) comprises an upper end having a flared shape that widens upwards, and a lower end connected to a pipe for discharging water into a bowl; • - and wherein the siphon comprises a closing member projecting into the inner cylinder at its upper end and partially blocking it, thereby reducing the volume of space that can be filled with air between two siphon priming cycles.
