1. An open-rim toilet comprising:
a main body (1) having a base (11) located in the lower part thereof;
a bowl (2) located above the base (11), having an access entrance (21) extending around the contour of the upper part of the toilet, and having an upper surface (22) extending from the front to the rear part of the toilet;
an inlet tray (3) located in the upper part of the bowl (2) below the upper surface (21) thereof, towards the rear of the toilet, where said inlet tray (3) has a tray inlet (31) and a tray outlet (32);
a rim (4) located in the upper internal part of the bowl (2) and which communicates fluidly with the outlet (32) of the inlet tray (3), wherein said rim (4) is open and is distributed along the access entrance (21) of the bowl (2), while having a series of ports (41) and windows (42) for water direction; and
an S-shaped discharge channel or trapway (5) located at the bottom of the bowl (2), having an inlet (51) and an outlet (52), wherein the inlet level (51) locates above the outlet level (52), comprising some brakes (54) arranged along the trapway (5), and having an intermediate point or weir (53) above the inlet (51) and outlet (52) level; wherein the bowl (2) has a geometrization defined by:

OG Complex Work Unit Math
where i is 1, 2 or and A_WM1 corresponds to the area described by the water mirror
leveled with the weir (53) of the discharge channel or trapway (5), cross-section area of the bowl (2) at the level of the highest point of the inlet (51) or dam and cross-section area of the bowl (2) at the level of the intermediate point of the inlet (51) in the discharge channel or trapway (5);
A_WL1 corresponds to the longitudinal area of the bowl (2); A_WT1 corresponds to three vertical
areas; and A_TWP1 corresponds to the area in the inlet (51) of the discharge channel (5),
where the orientation of the rim ports (41) is arranged pointing to an upper quartile (Q1) of the area described by the entrance to the discharge channel or trapway (5), a second quartile (Q2) of the plan area of the water mirror at the level of the spillway or weir (53) of the discharge channel or trapway (5), and a third quartile (Q3) of the plan area of the water mirror at the level of the discharge channel or trapway (5).
