ABSTRACT:
A flushing tank for a toilet has a housing which accommodates a body of flushing water. An evacuating unit is disposed in the flushing water and includes a flushing valve, a vertical tubular member whose lower end constitutes part of the flushing valve and a vertical suction pipe for the removal of foul odors from the toilet. The upper end of the suction pipe is connected to the upper end of the tubular member while the lower end of the suction pipe communicates with a filter or with a line which conducts foul odors away from the toilet. A suction generating unit draws foul air into and through the suction pipe. The tubular member is movable up-and-down to open and close the flushing valve. The evacuating unit is mounted in an opening in the bottom of the housing and the opening is connected to the toilet bowl. The flushing water flows through the flushing valve and the opening into the toilet bowl when the flushing valve is opened.
