ABSTRACT:
A toilet wherein the bowl is connected with the lower end of a flushing tank by a conduit which also serves for evacuation of malodorous air prior to flushing. The valve which can be opened to admit flushing liquid into the bowl has a valving element at the lower end of a duct which communicates with the conduit and the upper end of which is located above the level of flushing liquid in the tank. The apparatus for evacuating malodorous air has a pipe which is installed in the duct and has an intake above the liquid level as well as an outlet extending through and outwardly from the bottom wall of the tank. An odor barrier in the tank can seal or establish a path for the flow of air from the bowl by way of the conduit and duct and into the intake of the pipe so that a fan which is installed at the outlet of the pipe can draw air from the pipe and convey it into a flue. The odor barrier has a liquid containing vessel surrounding the intake of the pipe and being carried by the upper end of the duct, a vertically movable cap which normally dips into the liquid in the vessel and sealingly engages the intake of the pipe, a mechanism which can raise the cap, and a bell which dips into the supply of liquid in the tank and defines a compartment for the cap and the vessel.
