Toilet with efficient water flow path

Abstract

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

What is claimed is: 
     
         1 . A toilet comprising:
 a pedestal;   a tank supported by the pedestal;   an inlet passage associated with the pedestal; and   a fluidic device supported by the pedestal and configured to direct water from the inlet passage to a predetermined pattern.   
     
     
         2 . The toilet of  claim 1 , further comprising:
 a flush canister disposed in the tank and fluidly connected to the inlet passage and the fluidic device.   
     
     
         3 . The toilet of  claim 1 , further comprising:
 a cover plate cast into the toilet and connected to the fluidic device.   
     
     
         4 . The toilet of  claim 3 , wherein the cover plate and the fluidic device direct water in a fan shape. 
     
     
         5 . The toilet of  claim 3 , wherein the cover plate and the fluidic device direct water in a repeating pattern. 
     
     
         6 . The toilet of  claim 3 , wherein the cover plate and the fluidic device direct water in a pulsating flow pattern. 
     
     
         7 . The toilet of  claim 3 , wherein the cover plate and the fluidic device direct water in an expanding sheet flow pattern. 
     
     
         8 . The toilet of  claim 3 , further comprising:
 a slot formed in the cover plate and directed at the toilet.   
     
     
         9 . The toilet of  claim 1 , further comprising;
 a trapway fluidly connecting to an outlet of the toilet, wherein the trapway has a shape configured to induce a siphon to provide a pressure to suction waste water from the toilet during a flush cycle.   
     
     
         10 . A toilet comprising:
 a bowl having a sump in a bottom thereof;   an inlet passage formed in the bowl or the sump; and   a fluidic device supported by configured to direct water from the inlet passage to a predetermined pattern.   
     
     
         11 . The toilet of  claim 10 , wherein the fluidic device is cast as part of the toilet. 
     
     
         12 . The toilet of  claim 10 , further comprising:
 a flush canister fluidly connected to the inlet passage and the fluidic device.   
     
     
         13 . The toilet of  claim 10 , further comprising:
 a cover plate cast into the toilet and connected to the fluidic device.   
     
     
         14 . The toilet of  claim 13 , wherein the cover plate and the fluidic device direct water in a fan shape, a repeating pattern, a pulsating flow pattern, or an expanding sheet flow pattern. 
     
     
         15 . The toilet of  claim 13 , further comprising:
 a slot formed in the cover plate and directed at the bowl.   
     
     
         16 . A toilet comprising:
 a pedestal defining a toilet bowl;   a tank supported by the pedestal;   an inlet passage formed in the pedestal;   at least one fluidic device supported by the pedestal and configured to direct water from the inlet passage to a repeating water pattern; and   a flush canister disposed in the tank and fluidly connected to the inlet passage and the fluidic device.   
     
     
         17 . The toilet of  claim 16 , wherein the fluidic device is configured to provide a flow of water in a sheet-like layer substantially tangent to an inner surface of the toilet bowl. 
     
     
         18 . The toilet of  claim 16 , wherein the at least one fluidic device includes a plurality of fluidic devices fluidly connected to the inlet passage. 
     
     
         19 . The toilet of  claim 18 , wherein the plurality of fluidic devices are arranged at different positions around the toilet bowl. 
     
     
         20 . The toilet of  claim 18 , wherein the plurality of fluidic devices are cast with the toilet bowl.
