It is located on the left side with respect to the recess 200, and is located on the same side as the first water discharging section 20. The toilet body 45 is provided with two flush water passage systems for supplying pressurized flush water PW, and a discharge portion 95 composed of a trap pipe 93 and a socket 92 for discharging dirt in the bowl portion 11 to the outside. .

Next, the pressurized washing water flow system will be described.
The rear part of the flush toilet 10 has a hollow raised part 3 raised upward.
00 is set. A cover 301 is attached to the protruding portion 300, and a valve unit 110 is disposed inside the protruding portion 300. The valve unit 110 includes a pressurized water supply source (not shown), for example, a water supply path 100 branched from a water pipe.
Is connected to and receives tap water. The valve unit 110 includes an opening / closing valve mechanism (not shown) for controlling the flow of the pressurized washing water downstream through opening and closing of the pipeline, the flow of water to the second water discharge section water supply pipe 310, and the first A switching valve mechanism (not shown) for switching and controlling the flow of water to the water discharging section 20 is built in. The water supply channel 100 is connected to an opening / closing valve mechanism of the valve unit 110.

In this embodiment, the valve unit 110
The switching of the water flow destination by the switching valve mechanism during the opening of the pipeline was performed as follows. After operating the wash button,
The pressurized washing water PW (tap water) is passed through the first water discharging section 20 for a predetermined time (initial water passing). After that, the water supply destination is switched to the second water discharge section water supply pipe 310, and the washing water is supplied to the second water discharge section water supply pipe 310 for a predetermined time. Next, the water supply destination is switched to the first water discharge unit 20 again, and pressurized cleaning water (tap water) is supplied to the first water discharge unit 20 for a predetermined time (final water supply). The total time of these water passages is the pipeline opening / closing time, and the water passage time for each water passage is set in advance. The above-mentioned final water flow using the first water discharging section 20 is for storing a predetermined amount of stored water RW in the bowl section 11 in preparation for the next and subsequent flights. The above-mentioned valve unit 110 is connected to the second water discharge section water supply pipe 310 and the first water discharge section 20 with respect to the switching valve mechanism of the valve unit 110. Assuming that the water supply channel 100 and the first water discharge section 20 are pipes for introducing pressurized washing water (tap water) from an external water pipe into the flush toilet 10, the second water discharge section water supply pipe 310 is branched from the pipe.

Therefore, the discharge port 35 at the tip of the first water discharge section 20 guides the pressurized washing water PW to the water guide section 50 below the upper end section 51 of the bowl section. The pressurized cleaning water PW moves while rotating in a sliding manner in the bowl portion 11 and joins the stored water RW of the bowl portion 11 at an angle, and the stored water R
The turning force in the counterclockwise direction is efficiently applied to W. As a result, the stored water RW in the bowl part 11 is discharged to the outside from the discharge part 95 as a counterclockwise swirling flow. Since the swirling is caused by the pressurized cleaning water PW in this way, the effect of discharging the stored water RW and the dirt in the stored water is enhanced. Further, since the water guide section 50 is provided on the entire circumference of the bowl section 11, it also has a function of holding the pressurized washing water PW, thereby contributing to an increase in the design flexibility of the bowl section. Further, splashes generated while the water guide section 50 is in progress are prevented by the cover section 80. By inclining the substantially vertical portion 26 toward the outside of the toilet as in the present embodiment, the substantially vertical portion 26 can be further disposed from the water guide portion 50, so that a further effect of preventing water splashing is exhibited. .

Next, a method of attaching the discharge port 35 shown in FIG. FIG.
As shown in (b), the first water discharging section 20 is installed on the toilet body 45 in a state where the first water discharging section 20 is separated from the first water discharging section 20. After installation, the discharge port 35 is joined from the bowl portion 11 side. After the joining, the angle of the opening 33 is appropriately adjusted by a bellows-like opening angle adjusting unit 36. In the case of the present embodiment, after the angle is adjusted, the junction is improved in watertightness with an adhesive, and the opening angle adjuster 36 is also solidified with a solidifying agent, which is a measure for preventing mischief.
Therefore, the construction of the first water discharge section can be performed without any trouble, and the angle of the discharge port can be adjusted in accordance with the condition of the water supply section and the water supply, so that the cleaning performance of the bowl section is dramatically improved. Further, in this embodiment, since an adhesive is used for joining the discharge ports, aging and the like are extremely reduced.
