WATER CLOSET Russian patent published in 2017 - IPC E03D11/08 

FIELD: construction.

SUBSTANCE: water closet comprises the receiving bowl and the flushing water source ending with the inlet opening in the receiving bowl, in which the inner shape of the receiving bowl has the first vertical central plane which, in case of conventional mounting on the flat wall, is perpendicular to the supporting wall and intersects the waste water release in the middle, when the water closet It is supposed to be installed, as well as the user placed on the WC upright. Wherein the first vertical central plane is oriented perpendicular to the second vertical central plane which divides said WC into the front and the rear parts. The internal shape of the receiving bowl is asymmetric with respect to said vertical central plane. The internal shape of the receiving bowl forms a flow path for the flushing water, located deeper on the one side of the central plane than on the other, and which imparts the downward movement caused by the internal shape of the receiving bowl, to the flushing water rotational motion; so the internal shape of the reception bowl adds the component of motion, vertically directed downward. The flush water source and the inlet opening are made with the possibility to provide the flushing water flow into the receiving bowl with a preferred tangential velocity component relative to the internal shape of the receiving bowl and to perform the rotational motion of the flushing water in the receiving bowl. The internal shape of the receiving bowl is made without the flushing rim, namely without the peripheral channel for flushing water, having inlet openings directed downwards for draining flush water into said receiving bowl. In the above water closet, the flushing water, from the inlet opening for the flushing water, performs the rotational motion about the water level in the siphon. The rotational motion has a bias component as a spiral line. Water closet is used in the combination with a drain tank, in particular with a concealed drain tank. WC-unit has the above-described water closet and the drain tank, preferably the concealed drain tank, adapted to the flushing water amount limited by maximum 6 l.

EFFECT: creating a water closet improved in relation to the water flushing.
