A toilet comprises a compressed air tank (44, Fig. 2); an air compressor (46, Fig. 2), with air inlet 48, e.g. connected to the interior of the toilet bowl, and a compressor outlet (50, Fig. 2) connected to the air tank (44, Fig. 2); and a valved air outlet 52 connecting the air tank (44, Fig. 2) to the sewer-side of water trap 22. Injecting air through 52 creates a drag in the water trap 22 causing a pressure drop (Venturi effect) aiding flushing. Control means may control the compressor and valves. At the position where the air outlet 52 connects to the water trap 22, the angle 66 that the water trap makes with the horizontal may be between 1560 degrees, e.g. 2045 degrees. The toilet may have sensors (74, Fig. 1), 75 connected to the control means. Also claimed is a method corresponding to the above-described apparatus. |
