Toilet body

Abstract

A toilet body includes a toilet bowl part which has a bowl-shaped waste receiving surface and a water reservoir part, and a first water discharge part, in which the waste receiving surface has a shelf surface for guiding the flush water discharged from the water discharge hole into one side of the toilet bowl part in a circumferential direction, the shelf surface is structured so that a shape in a surface cut along a radial direction of the toilet bowl part is a flat surface, and a slope in the radial direction of the shelf surface in the rear region is set to be larger than a slope in the radial direction of the shelf surface in a lateral region of the waste receiving surface located on either the left or right side of the water reservoir part.

1 . A toilet body, comprising:
 a toilet bowl part which has a bowl-shaped waste receiving surface and a water reservoir part recessed downward from a lower end edge of the waste receiving surface;   a toilet drain channel which is connected to a bottom part of the toilet bowl part; and   a first water discharge part which discharges flush water from a first water discharge hole toward one side in a circumferential direction into the toilet bowl part to form a water flow which travels along a rear region of the waste receiving surface located behind the water reservoir part toward one side in a circumferential direction,   wherein the water reservoir part is structured to form an induction flow which pushes waste into the toilet drain channel by introducing a water flow from the rear of the toilet bowl part into the water reservoir part while contacting an upright wall surface provided on one side out of left and right sides of the water reservoir part,   the waste receiving surface has a shelf surface for guiding flush water discharged from the water discharge hole toward one side in the circumferential direction,   the shelf surface is structured so that a shape in a surface cut along a radial direction of the toilet bowl part is a flat surface, and   a slope in the radial direction of the shelf surface in the rear region is set to be larger than a slope in the radial direction of the shelf surface in a lateral region of the waste receiving surface located on either the left or right side of the water reservoir part.   
     
     
         2 . The toilet body according to  claim 1 , wherein the waste receiving surface has a connecting surface having a convexly curved surface shape which is connected to an upright wall surface of the water reservoir part and the shelf surface and is continued to the shelf surface, and
 the connecting surface is provided at least in the rear region of the waste receiving surface.   
     
     
         3 . The toilet body according to  claim 2 , wherein the connecting surface is also provided in the lateral region of the waste receiving surface, and
 a radius of curvature in a radial direction of the connecting surface in the rear region is set to be larger than a radius of curvature in a radial direction of the connecting surface in the lateral region.   
     
     
         4 . The toilet body according to  claim 1 , wherein the first water discharge part discharges flush water from the first water discharge hole to form a first swirling flow which travels backward along a first side portion of one of left and right sides of the toilet bowl part,
 the toilet body further comprising a second water discharge part which has a second water discharge hole which is formed in the first side portion behind the water reservoir part and discharges the flush water from the second water discharge hole toward one side in the circumferential direction into the toilet bowl part to form a first water flow introduced from the rear into the water reservoir part, and   wherein the first water flow merges with a portion of the first swirling flow and then is formed to be introduced from the rear into the water reservoir part while being in contact with the upright wall surface.   
     
     
         5 . A toilet body, comprising:
 a toilet bowl part which has a bowl-shaped waste receiving surface and a water reservoir part recessed downward from a lower end edge of the waste receiving surface;   a toilet drain channel which is connected to a bottom part of the toilet bowl part;   a first water discharge part which discharges flush water from a first water discharge hole toward one side in a circumferential direction into the toilet bowl part to form a first swirling flow traveling backward along a first side portion of one of left and right sides of the toilet bowl part; and   a second water discharge part which has a second water discharge hole formed at the first side portion behind the water reservoir part and discharges the flush water from the second water discharge hole toward one side in the circumferential direction into the toilet bowl part to form a first water flow introduced from the rear into the water reservoir part,   wherein the water reservoir part is structured to form an induction flow which pushes waste into the toilet drain channel by water flow introduced from the rear into the water reservoir part while being in contact with an upright wall surface provided on one side out of left and right sides of the water reservoir part, and   the first water flow merges with a portion of the first swirling flow and then is formed to be introduced from the rear into the water reservoir part while being in contact with the upright wall surface.   
     
     
         6 . The toilet body according to  claim 1 , wherein the toilet bowl part has a surface portion which constitutes an inner peripheral surface of the toilet bowl part and extends in a discharge direction along a central axis line of the first water discharge hole from an inner side surface of the first water discharge hole, and
 the surface portion is formed to extend toward an opposite side to the water reservoir part across an extension line of the central axis line in plan view as it goes toward the discharge direction from the inner side surface of the first water discharge hole.   
     
     
         7 . The toilet body according to  claim 1 , further comprising:
 a water passage which supplies the flush water to the first water discharge hole,   wherein the toilet bowl part has a hanging wall part which hangs from an upper end inner edge part of the toilet bowl part and has the first water discharge hole penetrating therethrough, and   an inner lower surface of the first water discharge hole is smoothly connected to an inner lower surface of the water passage and an inner surface of the toilet bowl part.
