Abstract (en)
[origin: WO2009066096A1] Disclosed is a toilet (1) comprising a toilet bowl (2), a passage which extends from the base of the toilet bowl to a drain outlet (30), and a gate (100), the gate having an open position which allows water within the toilet bowl to flow out of the drain outlet by way of the passage and a closed position in which the gate retains a continuous body of water (98) within the toilet bowl and a portion of the passage, up to a fill level (96), the toilet further comprising a divider (19) arranged to close off the passage above the fill level and to extend below the fill level at a location intermediate the toilet bowl and the water line (100) where the surface of the continuous body of water contacts the gate, to form a water trap in use when the gate is in the closed position and water is retained up to the fill level. The gate may be a flap operated by a hydraulic actuator (36), responsive to operation of a manually operable flush control, using mains water as the hydraulic fluid. Water is supplied by a spray ring around the rim of the toilet bowl. The toilet requires less water to flush than toilets including a conventional S-shaped water trap.
