Abstract
A flush toilet includes: a toilet main body; a rim which is provided on an upper portion of a toilet bowl of the toilet main body and which flows a flush water into the toilet bowl; and a water level detection sensor which is provided inside the rim.
Claims11
A flush toilet comprising;
- a toilet main body comprising a longitudinal axis extending down a center of the toilet main body from a rear of the toilet main body to a front of the toilet main body;
- a rim which is provided on an upper portion of a toilet bowl of the toilet main body and along which a flush water flows into the toilet bowl;
- and
- a detection part of a water level detection sensor, wherein the water level detection sensor is suspended within a cavity formed in the rim, wherein the cavity and the detection part are offset from the longitudinal axis, and the detection part is configured such that a lowermost position of the detection part is spaced apart from a lower wall of the cavity, at a position lower than an upper surface of a front and a side surrounding the toilet bowl, wherein the water level detection sensor is provided with a float which is attached to a lower portion of a supporting shaft extending vertically and is configured to move vertically, and the water level detection sensor is provided with a stopper fixed to the lower portion of the supporting shaft.
