Tankless toilet which operates independently of the water supply pressure

Abstract

The invention relates to a tankless intelligent toilet, using a direct flush technique, comprising a hinged pan ( 5 ), a bowl ( 2 ) with a water seal against odours ( 21 ), a funnel ( 3 ) below the bowl ( 2 ), for removing waste and a control unit ( 8 ) operationally connected to: a presence sensor ( 19 ); a flow sensor ( 12 ), which measures the amount of water flowing into the system; a solenoid valve ( 13 ), which allows or prevents the inflow of water into the toiler; an actuation mechanism ( 16 ), which opens and closes the hinged pan ( 5 ); and a locking mechanism ( 9 ) which locks the hinged pan ( 5 ) in the closed position. The flush mode of the toiler can be determined and the water supply to the system can be controlled, maintaining the water seal against odours, ensuring low water consumption with each flush, independently of the supply pressure, and guaranteeing a high level of performance.
