ABSTRACT:
There is a requirement when using toilets to prevent and/or remove the accumulation of odor-causing substances from the sidewall of the toilet bowl. This can easily be accomplished with ceramic toilets where the water is directed to swirl around by angled holes formed in the flushing rim. However, in stainless steel toilets, the material is too thin to form angled holes and the water has previously simply entered a flushing rim and run vertically down the wall of the toilet. This invention is an improvement in the flushing rim portion of a stainless steel toilet which causes the water to swirl around as in ceramic toilets, to effectively clean the inside of the toilet bowl. Instead of drilled holes, the rim has upturned notches in its lower wall which cause the flushing water to spray the toilet bowl wall in an overlapping pattern. The notches also contribute to the swirling action of the water.
