It is an object of the present invention to devise a lavatory flushing system of the afore described kind, more specifically the flushing channel, wliich ensure proper and even flushing even in the case of Indian type toilet pot with additional length of bowl.
This object is achieved by a separate channel provided along the gap in the open rim closet. The object is to use the open rim type channel but achieve the results of box rim type channel.

PRIOR ART
A lavatory flushdevice majnly comprises a being/bowl provided with a flushing rim which may be box type or open type.
A box type rim as illustrated in figure 5 and figure 6 is currently well known. This includes a bowl having a side wail with foot treads affixed thereto, said foot treads comitrising interconnected uppei- and lower portions definii^ there is between an annular space, the periphery of said lower space having apertures to allow escape there from of water introduced into said space during fiushing of the toilet.
The second known art is tlie open flush rim, as illustrated in fig 1 and fig 2, the rim being of the type havu:^ a fixed top wall and fixed at least partially downwardly directed aidewalls with one sidewall having a flushing water inlet- During the flushing cycle the flushing water is allowed with pressure, so as to carry certain amount of water along the peripheral length of the bowl and certaiu amount of water to fkH downwardly aloi^ with the wall of the bowl by the open rim.

In the box type Channel, the water from the inlet is carried into the bowl through the closed water channels provided along the circumferences

of the banl. The water channels provided along the circumference are


Advantages;


towards the end of the unit is weak, Also to usual casting problem, the flushing along the length is not uniform, as the Ihishing channel cannot be kept uniform along the length. So any casting imperfection, along the open end of the channel, results in uneven Hushii^ along the ler^th,
A open rim chaimel device currently knorwn is iUustrate
