According to the invention there are provided a collection tray (15) supported by the support means and collecting water from the flushing flow in such a manner as to increase the water level in its interior, and a half-siphon (20) with an inlet (23) which draws water from the collection tray (15), and an outlet (24) positioned at a lower level than the inlet (23), to discharge water to the outside of the collection tray (15).
