Abstract (en)
An equipment for ventilating a water-closet comprises a water-closet bowl (1) with a cavity (2) and a siphon (3) connected to the discharging system of the building; a flushing duct (4) sends the water to the water-closet bowl (1) through bores (5); a duct (9) of suction with a section of inlet (10) for the suction bores (11) for the gases which come in the duct (9); a ventilator (12) connected to an end of the duct (9) presents a delivery duct (13) connected to two discharging ducts (14,15); a two-way valve (16a, 16b) connects duct (13) to duct (14) or to duct (15); a check valve (17) allows the flow of the gases from the discharging duct (14) to the siphon (3) and prevents the reflow; a overflow sensor (66) is used for obtaining a signal to be sent to a suitable switch (21) intercepting the ventilator (12) feeding and closes an on-off valve (31) when the signal indicates a clogging of the bowl (1). <IMAGE>
