Anti splash toilet

Abstract

A toilet includes a bowl having a first surface and a second surface. The first surface forms an upper portion of the bowl, whereas the second surface forms a bottom portion of the bowl. The second surface includes a receiving portion for waste disposal when filled with water. The receiving portion includes a sloping surface with depth of water being shallowest at a front end and deepest at a back end of the receiving portion to facilitate movement of the waste. Splash is reduced and sanitation is improved during usage by such configuration.

1 . A toilet comprising:
 a bowl having a first surface and a second surface,
 the first surface forms an upper portion of the bowl, and 
 the second surface forms a bottom portion of the bowl, wherein the second surface includes a receiving portion for waste disposal when filled with water, the receiving portion having a sloping surface with depth of water being shallowest at a front end and deepest at a back end of the receiving portion to facilitate movement of the waste, wherein such configuration reduces splash and odor during usage. 
   
   
   
       2 . The toilet of  claim 1  wherein the sloping surface comprises a flat surface. 
   
   
       3 . The toilet of  claim 1  wherein the receiving portion comprises a length of about 15 to 25 cm from a rear end of a flush rim of the toilet to a front end of the receiving portion. 
   
   
       4 . The toilet of  claim 1  wherein maximum depth of the receiving portion is about 5.8 to 12.8 cm. 
   
   
       5 . The toilet of  claim 1  wherein the sloping surface comprises a constant slope. 
   
   
       6 . The toilet of  claim 5  wherein angle of the sloping surface is about 15 to 30°. 
   
   
       7 . The toilet of  claim 1  wherein the sloping surface comprises non-constant slope. 
   
   
       8 . The toilet of  claim 7  wherein the sloping surface comprises a first portion having a first angle θ 1  near a front end of the receiving portion and a second portion having a second angle θ 2  near a back end of the receiving portion. 
   
   
       9 . The toilet of  claim 8  wherein θ 2  is greater than θ 1 . 
   
   
       10 . The toilet of  claim 1  wherein the sloping surface comprises a length of about 22.8-25.5 cm from a front end to a rear end of a bottom surface of the receiving portion. 
   
   
       11 . The toilet of  claim 1  further comprises a collection reservoir which is located behind the bowl and in communication with the sloping surface. 
   
   
       12 . The toilet of  claim 11  wherein the sloping surface further comprises an extended sloping surface which forms a portion of the collection reservoir having a higher gradient relative to the sloping surface of the receiving portion. 
   
   
       13 . A toilet comprising:
 a bowl having a first surface and a second surface,
 the first surface forms an upper portion of the bowl, and 
 the second surface forms a bottom portion of the bowl, wherein the second surface includes a receiving portion for waste disposal when filled with water, the receiving portion having a sloping surface; and 
   a collection reservoir located behind the back of the bowl and in communication with the sloping surface, wherein such configuration reduces splash and improves sanitation during usage.   
   
   
       14 . The toilet of  claim 13  wherein the sloping surface having depth of water being shallowest at a front end and deepest at a back end of the receiving portion. 
   
   
       15 . The toilet of  claim 13  wherein the sloping surface comprises a flat surface. 
   
   
       16 . The toilet of  claim 15  wherein maximum depth of the receiving portion is about 5.8 to 12.8 cm. 
   
   
       17 . The toilet of  claim 13  wherein the sloping surface comprises a constant slope. 
   
   
       18 . The toilet of  claim 13  wherein angle of the sloping surface is about 15 to 30°. 
   
   
       19 . The toilet of  claim 13  wherein the sloping surface comprises a first portion having a first angle θ 1  near a front end of the receiving portion and a second portion having a second angle θ 2  near a back end of the receiving portion, wherein θ 2  is greater than θ 1 . 
   
   
       20 . A method of discharging waste from a toilet comprising:
 providing a toilet bowl with a first surface and a second surface,
 wherein the second surface when filled with water forms a receiving portion for waste disposal, the receiving portion having a sloping surface with sufficient length and depth to facilitate movement of waste and reduces splash during usage; and 
   providing a collection reservoir behind the back of the bowl, wherein the collection reservoir is not visible to the user.
