Toilet arrangement for swirl flushing

Abstract

A toilet bowl of a toilet, the toilet bowl comprising: a toilet base bowl comprising an upper portion and a toilet rim disposed in the upper portion of the toilet base bowl. The toilet rim comprises a tubular structure comprising a first end configured to receive water, a second end, and a middle section disposed between the first end and the second end. The water is configured to flow in a water flow direction towards the second end, and the second end is closed. The toilet rim also comprises a plurality of outlet conduits extending from the middle section directed towards an interior of the toilet base bowl. The plurality of outlet conduits is directed at an acute angle relative to the water flow direction, such that plurality of outlet conduits allow the water to enter the interior of the toilet base bowl in a swirl-flow manner.

1 . A toilet comprising:
 a toilet bowl having a rim with a tubular structure including a plurality of outlet conduits;   a flush tank configured to store water;   a supply pipe;   a valve unit positioned within the supply pipe and configured to allow and restrict a supply of water from the flush tank to the toilet bowl; and   an adapter configured to couple the tubular structure of the rim of the toilet bowl to the supply pipe.   
     
     
         2 . The toilet of  claim 1 , wherein the adapter is formed from an elastomer material. 
     
     
         3 . The toilet of  claim 1 , wherein the plurality of conduits are conduit pipes extending outward. 
     
     
         4 . The toilet of  claim 3 , wherein the conduit pipes are angled at an acute angle. 
     
     
         5 . The toilet of  claim 1 , wherein the tubular structure includes a first end and a second end 
     
     
         6 . The toilet of  claim 5 , wherein the first end is higher than the second end so that a average velocity at the first end is higher than an average velocity at the second end. 
     
     
         7 . The toilet of  claim 6 , wherein the average velocity at the second end corresponds to less water usage. 
     
     
         8 . The toilet of  claim 5 , wherein the tubular structure includes an elliptical cross-section area. 
     
     
         9 . The toilet of  claim 5 , wherein a cross-section area a predetermined section of the tubular structure is 50% or more of a cross-section area at the first end of the tubular structure. 
     
     
         10 . The toilet of  claim 5 , wherein a cross-section area a predetermined section of the tubular structure is 50% or less of a cross-section area at the first end of the tubular structure. 
     
     
         11 . A toilet bowl of a toilet, the toilet bowl comprising:
 a toilet base bowl comprising an upper portion; and   a toilet rim disposed in the upper portion of the toilet base bowl, the toilet rim comprising:
 a tubular structure comprising a first end configured to receive water, a second end, and a middle section disposed between the first end and the second end, wherein the water is configured to flow in a water flow direction towards the second end, and the second end is closed; and 
 a plurality of outlet conduits extending from the middle section directed towards an interior of the toilet base bowl, the plurality of outlet conduits being directed at an acute angle relative to the water flow direction, such that plurality of outlet conduits allow the water to enter the interior of the toilet base bowl in a swirl-flow manner, wherein the tubular structure comprises a first section including the first end, a second section, a third section, and a fourth section including the second end, 
   
       \wherein:
 a cross-section area at an end of the second section in the water flow direction is 36% of the cross-section area at the first end included in the first section of the tubular structure, or 
 a cross-section area at an end of the third section in the water flow direction is 25% of the cross-section area at the first end included in the first section of the tubular structure, or 
 a cross-section area at the second end included in the fourth section of the tubular structure in the water flow direction is 9.5% of the cross-section area at the first end included in the first section of the tubular structure. 
 
     
     
         12 . A toilet comprising:
 a toilet bowl having a rim with a tubular structure having a plurality of outlet conduits;   a supply pipe;   a valve unit positioned within the supply pipe and configured to allow and restrict a supply of water to the toilet bowl; and   an adapter configured to couple the tubular structure of the rim of the toilet bowl to the supply pipe.   
     
     
         13 . The toilet of  claim 12 , wherein the adapter is formed from an elastomer material. 
     
     
         14 . The toilet of  claim 12 , wherein the plurality of conduits are conduit pipes extending outward. 
     
     
         15 . The toilet of  claim 14 , wherein the plurality of conduits are angled at an acute angle. 
     
     
         16 . The toilet of  claim 12 , wherein the tubular structure includes a first end and a second end 
     
     
         17 . The toilet of  claim 16 , wherein the first end is higher than the second end so that a average velocity at the first end is higher than an average velocity at the second end. 
     
     
         18 . The toilet of  claim 17 , wherein the average velocity at the second end corresponds to less water usage. 
     
     
         19 . The toilet of  claim 16 , wherein the tubular structure includes an elliptical cross-section area. 
     
     
         20 . The toilet of  claim 16 , wherein a cross-section area a predetermined section of the tubular structure is 50% or more of a cross-section area at the first end of the tubular structure.
