Toilet with spinning bowl and water jet

Abstract

A toilet uses very little water to flush waste material. To flush, a lower part of the bowl is lowered from a sealed position against a bowl side to an unsealed position spaced from the bowl side, and spun. Centrifugal force and a jet of water flush the inside of the bowl bottom. Odors are controlled by sealing the bowl bottom to the bowl side.

1 . A toilet, comprising: 
 a bowl side and a bowl bottom defining a bowl space, wherein said bowl bottom is arranged and adapted to move between a sealed position with respect to said bowl side and an unsealed position wherein said bowl bottom is spaced from and below said bowl side;    means for rotating said bowl bottom when said bowl bottom is in the unsealed position;    a flush switch arranged to move said bowl bottom from the sealed position to the unsealed position and to operate said means for rotating said bowl bottom; and    a waste collection region below said bowl space that is arranged to receive waste from said bowl bottom that has been expelled by movement of said bowl bottom to the unsealed position and by operation of said means for rotating said bowl bottom.    
   
   
       2 . The toilet of  claim 1 , wherein said means for rotating said bowl bottom comprises a liquid discharge nozzle extending from said bowl side in a direction offset from a rotational center of said bowl bottom, and wherein said flush switch causes a liquid to flow from said nozzle onto said bowl bottom to rotate said bowl bottom.  
   
   
       3 . The toilet of  claim 2 , further comprising a governor that limits a rotational speed of said bowl bottom.  
   
   
       4 . The toilet of  claim 2 , wherein said nozzle is arranged to emit a fan-shaped jet of the liquid and a majority of the liquid is offset from the rotational center of said bowl bottom.  
   
   
       5 . The toilet of  claim 1 , wherein said means for rotating said bowl bottom comprises a motor that rotates said bowl bottom.  
   
   
       6 . The toilet of  claim 1 , further comprising an arm with one end that supports a rotational center of said bowl bottom and an opposite end that is pivotally actuated by said flush switch so that said arm moves in an arc between the sealed and unsealed positions.  
   
   
       7 . The toilet of  claim 6 , wherein said means for rotating said bowl bottom comprises a motor that is attached to said arm and that rotates said bowl bottom.  
   
   
       8 . The toilet of  claim 7 , further comprising a liquid discharge nozzle extending from said bowl side adjacent to said one sector in a direction toward a rotational center of said bowl bottom and wherein said flush switch causes a liquid to flow from said nozzle onto said bowl bottom.  
   
   
       9 . The toilet of  claim 1 , wherein said arm is arranged so that when said bowl bottom is in the sealed position a periphery of said bowl bottom is sealed to a bottom of said bowl side and so that when said bowl bottom is in the unsealed position one sector of the periphery of said bowl bottom is closer to the bottom of said bowl side than a radially opposite sector.  
   
   
       10 . The toilet of  claim 1 , further comprising a toilet cover with a seal that seals to an upper part of said bowl side to enclose said bowl space.  
   
   
       11 . The toilet of  claim 1 , wherein said bowl space is water-tight when said bowl bottom is in the sealed position.  
   
   
       12 . The toilet of  claim 1 , further comprising an air gap between said bowl bottom and said bowl side when said bowl bottom is in the sealed position.  
   
   
       13 . A toilet, comprising: 
 a bowl side inside a bowl support;    a bowl bottom that is movable between a sealed position abutting said bowl side and an unsealed position spaced from said bowl side, said bowl bottom being rotatable about an axis when in the unsealed position;    an arm with one end attached to said bowl support and an opposite end to which said bowl bottom is rotatably attached;    a liquid discharge nozzle that directs a liquid onto said bowl bottom;    a flush switch arranged to move said arm so that said bowl bottom moves from the sealed position to the unsealed position and to operate said liquid discharge nozzle; and    a waste collection region within said bowl support below said bowl bottom.    
   
   
       14 . The toilet of  claim 13 , further comprising a motor that is attached to said arm and that rotates said bowl bottom.  
   
   
       15 . The toilet of  claim 13 , wherein said liquid discharge nozzle extends from said bowl side in a direction toward a rotational center of said bowl bottom.  
   
   
       16 . The toilet of  claim 13 , wherein said opposite end of said arm supports a rotational center of said bowl bottom and said one end is pivotally actuated by said flush switch so that said arm moves in an arc between the sealed and unsealed positions.  
   
   
       17 . The toilet of  claim 13 , wherein said arm is arranged so that when said bowl bottom is in the sealed position an entire periphery of said bowl bottom is sealed to said bowl side and so that when said bowl bottom is in the unsealed position one sector of the periphery of said bowl bottom is closer to said bowl side than a radially opposite sector.  
   
   
       18 . The toilet of  claim 13 , wherein said liquid discharge nozzle extends from said bowl side in a direction offset from a rotational center of said bowl bottom, and wherein said flush switch causes a liquid to flow from said nozzle onto said bowl bottom to rotate said bowl bottom.
