Abstract

Free-standing toilet with cast-on toilet tank, comprising a ceramic toilet body and a ceramic toilet tank, wherein the pressure cast toilet body ( 2 ) has an annular flange ( 11 ) located on the upper rim of its bowl section ( 10 ), which annular flange continues circumferentially around and extends substantially horizontally toward the inside of the bowl section ( 10 ) and serves as a border for flushing water that is introduced below the annular flange ( 11 ) by means of an introduction unit ( 14 ), and in that the toilet tank ( 3 ), which is also pressure cast, is fixedly joined to the toilet body ( 2 ) by means of a ceramic bonding.

First claim

The invention claimed is:

1. Free-standing toilet with cast-on toilet tank, comprising:
a ceramic toilet body and a ceramic toilet tank, wherein the toilet body has a toilet bowl with an annular flange located on an upper rim of the bowl,
the annular flange continues circumferentially around and extends substantially horizontally toward an inside of the bowl and serves as a border for flushing water that is introduced below the annular flange by means of an introduction unit,
the toilet tank, which is also pressure cast, is fixedly joined to the toilet body by means of a ceramic bonding,
a rim flange which is directed toward a bottom of the bowl is formed on the annular flange in a region close to the toilet tank and extends only partially around the annular flange in order to create an installation space for the introduction unit, and
the introduction unit is a hollow body and is installed in the installation space, the introduction unit has a water inlet at a rear side of the introduction unit and two water outlets at a front side of the introduction unit from which flushing water is introduced below the annular flange and into the bowl, and
a first flush water supply line connected at one end to the toilet tank and at another end to the water inlet of the introduction unit.

2. Free-standing toilet according to claim 1 , wherein
the rim flange continues circumferentially around the annular flange for at least 90°.

3. Free-standing toilet according to claim 1 , wherein
a first through hole for accommodating the first flush water supply line from the toilet tank to the introduction unit, is located in a rear upper rim of the bowl.

4. Free-standing toilet according to claim 3 , wherein
the first flush water supply line leading from the toilet tank has a branch to a second flush water supply line that leads to a second through hole located in a front of the lower region of the bowl.

5. Free-standing toilet according to claim 1 , wherein
a second through hole for connecting a second flush water supply line is located in a front of a lower region of the bowl, and a connection is located, as an extension of the second through hole, on a rear side of the bowl opposite the second through hole for a serpentine suction siphon enabling a suction-driven discharge from the bowl.

6. Free-standing toilet according to claim 5 , wherein
the ceramic suction siphon is also fixedly joined to the toilet body by means of a ceramic bonding achieved by casting-on or by means of adhesive bonding carried out post-firing.

7. Free-standing toilet according to claim 1 , wherein
the introduction unit is made of plastic.
