<p>PROBLEM TO BE SOLVED: To provide a water closet device which is a type of supplying washing water to a bowl part by a jet pump, and does not decrease the efficiency of jet pump effect in spite of having a configuration of storing the whole of an inverted U-shaped throat pipe in a small tank.SOLUTION: A water closet device includes a tank and a jet pump unit. A throat pipe of the jet pump unit has a first straight line part formed so as to linearly extend obliquely upward from a suction port 331 and a second straight line part formed so as to linearly extend toward the inlet of a conduit located on the lower side, and the whole of the throat pipe is formed in an inverted U shape in a side view. The throat pipe is arranged so that an angle formed by a central axis of the second straight line part with respect to the vertical direction is smaller than an angle formed by a central axis of the first straight line part with respect to the vertical direction in a side view.</p> |
