DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a bottom-flushing flush-type toilet stool, and more particularly to the connection structure which enables simple connection between the drain port of the toilet stool and the building-mounted drainpipe when replacing a toilet stool with a new one.
BACKGROUND ART
The general installation construction of a bottom-flushing flush-type toilet stool in the prior art is such that a drain port on the bottom surface of the toilet stool is received by a special flange provided on the top end of a drainpipe provided in the building, thereby linking the two in a sealed manner.
In the case in which a new toilet stool is to be installed in an existing building, the position of the building-mounted drainpipe inside the toilet stool is pre-established. If the specifications of the toilet stool to be newly installed are different than those of the previously installed toilet stool, the relative front-to-back position of the drain port of the toilet stool with respect to the toilet stool itself can be different. For that reason, when installing the toilet stool, when using the building-mounted drainpipe position as the reference, there are many cases in which the toilet stool itself will interfere with a wall or other part of the toilet stool.
To eliminate this type of interference in this type of installation, there is a connecting part, as noted in Utility Model Laid-Open Publication Hei 2-144085 (1990), which absorbs the positional skew between the drainpipe of the building and the drain port of the toilet stool.
This connecting part has two parts: a toilet stool side connecting part which links to the drain port of the toilet stool, and a drainpipe connecting part which links to the drainpipe of the building, the drainpipe connecting part being connected in a direction which is approximately horizontal from the peripheral surface of the toilet stool side connecting part, which is oriented approximately upright, the end of this drainpipe connecting part being bent downward and connected to the drainpipe. Using this type of connecting part, by cutting off the horizontal part of the drainpipe connecting part in accordance with the positional skew between the drain port and the drainpipe to adjust its length, it is possible to make connection to the flow passage, even if the positional relationship between the drain port of the toilet stool and the drainpipe of the building differs between individual locations.
However, to be able to accommodate even the case in which the positional skew between the drain port and the drainpipe is large, it is necessary to make the horizontal part of the drainpipe side connecting part long. For this reason, because the connecting part includes a horizontal part, on one end of which is a drain port connection part and a flange part that links to the drainpipe connecting part, this part itself becomes large. In a horizontal part that is large in comparison with the flange part that connects to the drainpipe, there is a large possibility that its end exhibits twisting deformation or the like. When this type of twisting occurs, the installation will involve a skew between the centers of the drainpipe and the drain port, thus greatly affecting the seal. In addition, because the connection part is L-shaped, in addition to making the installation work difficult, it is easy for bending to occur in the cutting plane.
Also, because it is necessary when performing the installation to cut off part of the horizontal part of the drainpipe side connecting part, erroneously cutting this off to the wrong dimension at the installation site can be envisioned. Therefore, not only is the cutting off task troublesome, but also the quality of the installation is established by the quality of this cutting off process, thereby presenting a problem in ease of installation.
In addition, because the connections of the connecting part to the drain port and to the drainpipe are made using an adhesive and a seal, working with the adhesive is troublesome, and if insuff
