Problems solved by technology

[0009] However, in the above configuration, when the washing water is supplied to the bowl, the air in the water tank is sucked into the throat even though the washing is not completed, and the efficiency of the jet pump action is lowered.
It is considered that this phenomenon is because in a tank with a short dimension in the front-to-back direction, water located far from the opening of the throat pipe cannot smoothly reach the opening of the throat pipe, so that the water surface in the tank as a whole cannot become horizontal

Abstract

A flush toilet apparatus includes a tank and a jet pump unit. The tank includes: a first tank portion; and a second tank portion formed so as to extend part of a bottom wall of the first tank portion downward. The jet pump unit includes a throat pipe provided with a suction port that is an inlet of water, and at least the part of the second tank portion is formed at a position overlapping with the suction port when viewed from the top.

Description

technical field [0001] The present invention relates to a flush toilet device which discharges dirt to a drainpipe by using washing water. Background technique [0002] As a method for supplying flush water to the bowl of a flush toilet device, a method of supplying water using high water pressure in a water pipe (direct pressure type) or a method of supplying water from a water tank placed at a high place is known. (water tank type). [0003] Since the direct pressure flush toilet device directly supplies the water in the water pipe to the bowl, continuous washing is possible. However, since the flow rate of the washing water decreases when the water pressure in the water supply pipe is low, there is a problem that the washing performance is lowered. [0004] Since the cistern type flush toilet device utilizes the potential energy of the water stored in the cistern to supply water to the basin, a large flow of flushing water can be supplied without being affected by the w...
