ABSTRACT:
A toilet has a toilet bowl and a flushing tank which accommodates a supply of flushing liquid for the bowl. The bowl, which discharges into a waste line, is connected to the flushing tank by a flushing pipe. A second pipe for evacuating odors from the bowl likewise leads from the bowl to the tank. This evacuating pipe has an open end in the bottom of the bowl and a second end in the tank. An air duct hooked into the waste line also extends into the tank and can be caused to communicate with the evacuating pipe when the toilet is in use. The air duct is provided with a blower which functions to convey odors from the bowl to the waste line via the evacuating pipe, flushing tank and air duct. A liquid seal cuts off communication between the air duct and evacuating pipe when the toilet is not in use to prevent backflow of odors from the waste line to the bowl. The liquid seal is located in the flushing tank and is established using the flushing liquid accommodated by the same.
