Flush toilet
A flush toilet of the present invention includes a bowl; a toilet drainage water pathway which communicates with the bowl and a drainage water socket and into which a cleaning water flows from the bowl; and a valve portion which includes a rotating axis and a flapper, and which is configured to open and close the toilet drainage water pathway, the rotating axis being provided in the toilet drainage water pathway, the flapper being connected to the rotating axis and being provided so as to be capable of rotating about the rotating axis.
1. A flush toilet comprising:
a bowl;
a toilet drainage water pathway which communicates with the bowl and a drainage water socket and into which a cleaning water flows from the bowl; and
a valve portion which includes a rotating axis and a flapper, and which is configured to open and close the toilet drainage water pathway, the rotating axis being provided in the toilet drainage water pathway, the flapper being connected to the rotating axis and being provided so as to be capable of rotating about the rotating axis, wherein the rotating axis and a connection part between the rotating axis and the flapper are in a top part or a downstream side of the top part.
2. The flush toilet of claim 1 , wherein
the valve portion includes a valve portion main body which configures a portion of a toilet drainage water pathway,
the rotating axis and the flapper are provided in the valve portion main body, and
the valve portion main body and the flapper are made of resin.
3. The flush toilet of claim 2 , wherein
the valve portion main body is formed as a single body.
4. A flush toilet comprising:
a bowl;
a toilet drainage water pathway which communicates with the bowl and a drainage water socket and into which a cleaning water flows from the bowl; and
a valve portion which includes a rotating axis and a flapper, and which is configured to open and close the toilet drainage water pathway, the rotating axis being provided in the toilet drainage water pathway, the flapper being connected to the rotating axis and being provided so as to be capable of rotating about the rotating axis,
wherein an enlarging part which has an upper portion which is larger than an upstream side at least in a height direction is provided in a conduit, the cleaning water of the valve portion main body flowing in the conduit; and
the enlarging part includes the rotating axis and a connection part between the rotating axis and the flapper.
5. The flush toilet of claim 1 , wherein
the valve portion is configured such that a gap is formed between an inner wall of the toilet drainage water pathway and a peripheral part of the flapper in a state where the flapper is open.
6. A flush toilet comprising:
a bowl;
a toilet drainage water pathway which communicates with the bowl and a drainage water socket and into which a cleaning water flows from the bowl; and
a valve portion which includes a rotating axis and a flapper, and which is configured to open and close the toilet drainage water pathway, the rotating axis being provided in the toilet drainage water pathway, the flapper being connected to the rotating axis and being provided so as to be capable of rotating about the rotating axis,
wherein the valve portion is configured so as to maintain a watertight seal between an inner wall of the toilet drainage water pathway and a peripheral part of the flapper that faces the inner wall of the toilet drainage water pathway in a state where the flapper is open.
