Embodiment Construction

[0071]The rimless toilet described herein is designed to be able to incorporate advantages achieved in flush efficiency from use of a jetted toilet flush system as well as the advantages of bowl cleanliness and an enlarged interior bowl pan or target area associated with the rimless design configuration. The toilet is able to provide strong flushing and cleaning capability without use of a rim channel wash function and without pressurization of rim water as in traditional prior art jetted toilet bowls.

[0072]The toilet is able to provide good flush capability consistent with today's 6.0 liters / flush (1.6 gallons / flush toilets), and preferably with toilets utilizing 4.8 liters / flush (1.28 gallons / flush), while allowing for a clean bowl after flushing and without the deposition of dirt and germs that can occur in conventional toilets having an overhanging rim channel. The balance in achieving excellent bowl cleanliness in a jetted bowl typically requires rim channel assistance, especia...

Abstract

A siphonic gravity-powered toilet is provided that is a rimless toilet and includes a toilet bowl assembly having a body and an inlet for receiving fluid. The toilet bowl has an interior bowl surface with an upper peripheral portion configured to have a shelf formed therein below an upper peripheral edge of the toilet bowl. The rimless toilet includes a jet having a jet inlet, an outlet and at least one jet channel. A manifold is included which is configured so that fluid entering an inlet of the toilet bowl assembly divides into a portion that enters the inlet of the direct-fed jet and a portion that enters an interior area of the toilet bowl. At least one toilet bowl inlet port is positioned at an upper rear portion of the toilet bowl. The at least one inlet port is configured to receive fluid from the manifold into the interior area of the toilet bowl such that at least a portion of the fluid travels along the shelf of the toilet bowl prior to passing into a lower portion of the toilet bowl.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61 / 603,232, filed Feb. 24, 2012, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to the field of toilets for removal of human and other waste. The present invention further relates to the field of a toilet that operates for effective flushing without a rim.[0004]2. Description of Related Art[0005]Various toilets for removing waste products, such as human waste, are well known. Most toilets are powered by gravity and generally have two primary sections: a tank and a bowl. The tank and bowl can be separate pieces which couple together to form the toilet system (commonly referred to as a two-piece toilet) or can be combined into one integral unit (typically referred to as a one-piece toilet).[0006]The tank, which is usually posit...
