Abstract
A water conserving toilet having a set of holes around the rim to provide a washing of the bowl includes enlarged holes towards the front of the rim to create a focused jet of water used to initiate siphon action. The enlarged holes are positioned on an elevated multi-plateau boss within the rim. The boss extends beyond the highest normal level of water in the rim and has a vent to vent air from the rim. A sloped entry within the receiving chamber connects the tank of the toilet to the rim to further increase the momentum of this water. The jet from the enlarged front holes in the rim is further focused by a groove extending on the bowl's lower wall.
