发明名称 Odor exhausting apparatus for water closet
摘要 The object of this invention is to provide a toilet and an odor exhausting apparatus for such toilets, designed to quickly suck odor from the toilet bowl to a chimney pot installed on the rooftop during defecation or urination so as to quickly expel the odor into the atmosphere outside a house. In the apparatus, the seat (3) has a cavity (1d), a plurality of odor suction ports (1f), a tubular hinge joint (2) and an odor outlet port (1e). A connection pipe (6), having an inlet port (6a), is set within the hinge joint (2). A seat cover (8) is coupled to the connection pipe (6) through a toothed engagement. A tubular shaft (7), having an inlet port (7a), is rotatably set within the connection pipe (6), and communicates with the atmosphere outside the house through a pipeline (12). When the cover (8) is closed, the port (7a) is closed by the sidewall of the connection pipe (6). However, when the cover (8) is opened, the port (7a) communicates with the port (1e) of the seat (3) through the port (6a) of the connection pipe (6), thus automatically expelling odor from the toilet bowl to the atmosphere due to suction force of the pipeline.
