Above-mentioned urinal face 2 in Sealing Surface below 11 has for the swirling flow collision with rinse water makes the mobile guide mechanism 6 towards drain outlet portion 4.In other words, in Sealing Surface, on the above-mentioned urinal face 2 below 11, there is guide mechanism 6.And guide mechanism 6 is configured to the flowing towards drain outlet portion 4 of swirling flow that makes the rinse water of colliding.
In present embodiment, as shown in Fig. 1 ~ Fig. 4, Fig. 7 ~ Figure 10, for conflicting with swirling flow, make the protuberance 7 flowing towards drain outlet portion 4 be formed on urinal face 2.In present embodiment, this protuberance 7 forms guide mechanism 6.
As shown in Fig. 2, Figure 10, protuberance 7 is in a direction one side of the left and right directions of urinal 1 and outstanding formation on the urinal face 2 of the contrary side of the side with being provided with water supply unit 10.
That is,, as shown in Fig. 1 ~ Fig. 4, Fig. 6, Fig. 8 ~ Figure 10, protuberance 7, on the left and right directions of urinal 1, is formed on a side contrary with a side who is formed with high bottom 16.Depressed part 17 is formed between high bottom 16 and protuberance 7.That is the, (side contrary with water supply unit 10 of the above-mentioned the opposing party's side on the left and right directions of urinal face 2; The 2nd side) upper, form protuberance 7 (guide mechanism 6).
And the people that above-mentioned the opposing party's side (right side of Figure 10) of this protuberance 7 side opening drain outlet portion 4 is formed into upper side opening nearby.Protuberance 7 is given prominence to formation (with reference to Fig. 3, Fig. 4) from the side of the opposite side (right side of Figure 10) of urinal face 2 towards the interior side of urinal 1.
The front surface of the ratio drain outlet portion 4 more close people part nearby of protuberance 7 becomes swirling flow and collides face 23.That is, the face of the front side of protuberance 7 becomes swirling flow collision face 23.The corner part that swirling flow is collided between face 23 and urinal face 2 becomes obtuse angle.Specifically, as shown in Figure 9, this swirling flow is collided corner part face 23, that the protuberance 7 of urinal face 2 becomes with not outstanding position while overlooking becomes obtuse angle, and, to leave this corner part, more tilt with the near mode of drain outlet portion 4 side joints (represented in the accompanying drawings tilt with curved surface shape example).
The side 8 of drain outlet portion 4 sides and the medial surface 9 of drain outlet portion 4 of protuberance 7 are connected smoothly.That is, the side 8 of drain outlet portion 4 sides of protuberance 7 is connected with the medial surface 9 of drain outlet portion 4 with level and smooth face.
The flushing water-closet bowl 5 of said structure as shown in the solid line of Figure 11, the front opening 15A of return trap socket 15 towards above posture (the 1st posture) under, rinse water is deposited in urinal 1.User defecates and the convenience of urine etc. under this state.
Cleaning after facilitating is carried out with the process of following (1) ~ (3).
First, (1) supplies with rinse water mobile in the mode of swirling flow from water supply unit 10, carries out thus front water flowing (cleaning of the part not had by the water of urinal face).(2) continue supply with ensuing rinse water and flow with swirling flow, meanwhile, so that front opening 15A mode is downward rotated return trap socket 15, discharge the rinse water of foul and urinal 1 interior retention.(3) then, when continuing to supply with rinse water, so that the mode of front opening 15A towards top rotates backward return trap socket 15, in the interior retention rinse water of urinal 1.
Here, when rinse water is circled round with the front water flowing of above-mentioned cleaning process (1), foul flows urinal 1 is interior by swirling flow, and following situation may occur: the foul in drain outlet portion 4 by head-to-foot portion 3, or moves to the position away from drain outlet portion 4 of bottom 3 from drain outlet portion 4.
Like this, foul in drain outlet portion 4 from drain outlet portion 4 by head-to-foot portion 3, or move to bottom 3 away from the position of drain outlet portion 4 time, as shown in the conventional example of Figure 13, when cleaning process (2) is discharged booty, after foul 30, the water yield of mobile rinse water tails off.
And, the distance that foul is transported by rinse water in sewer pipe (foul transports distance) is subject to the impact of the water yield of rinse water mobile after foul, when after foul, the water yield of mobile rinse water tails off, the foul that foul is transported in sewer pipe by rinse water transports distance and shortens.
But in present embodiment, the bottom 3 of urinal face 2 is formed with high bottom 16 at the left and right directions of the people of drain outlet portion 4 part nearby one-sided, at another one-sided depressed part 17 that is formed with.This height bottom 16 is positioned at a side identical with a side that is provided with water supply unit 10 (high bottom 16 makes the side of left and right directions of the bottom 3 of urinal face 2 uprise and form, and water supply unit 10 is formed on the top of an above-mentioned side of the left and right directions of urinal face 2) on left and right directions.That is, high bottom 16, on the flow direction of rinse water, is formed on the place ahead of drain outlet portion 4.Therefore, the rinse water of supplying with from water supply unit 10 is in edge circumferential (counter clockwise direction of Figure 10) after 2 convolutions of urinal face, and with wall 24 (Fig. 9 reference) collision of high bottom 16, its flow of water dies down.And foul also collides this wall 24, depressed part 17 becomes and easily retains foul.Therefore, present embodiment is by forming high bottom 16 and depressed part 17, even if rinse water with the front water flowing convolution of above-mentioned cleaning process (1), also can suppress foul, due to swirling flow, flows and moves urinal 1 is interior.
That is, suppress foul in drain outlet portion 4 from drain outlet portion 4 by head-to-foot portion 3, or, be moved on the position away from drain outlet portion 4 of bottom 3.
Like this, in cleaning process (2), when making return trap socket 15 rotate in front opening 15A mode downward, be first deposited in foul in drain outlet portion 4 and from the front opening 15A of return trap socket 15, to sewer pipe, discharge to return trap socket 15 side flow with together with water in drain outlet portion 4.Follow-up be deposited in water in urinal 1 from the rear of foul according to the sequential flow of drain outlet portion 4, return trap socket 15 through this drain outlet portion 4, return trap socket 15, and discharge to sewer pipe from the front opening 15A of return trap socket 15.
Therefore, while transporting foul in sewer pipe, in the cleaning water yield of the rear of foul one side, can become many, foul transports distance can be elongated.
And, because rinse water gathers depressed part 17 and flows into discharging oral area 4, therefore with the less cleaning water yield, just can improve cleaning performance.And rinse water gathers depressed part 17 and flows to discharging oral area 4, therefore compares with the situation that does not form depressed part 17 quickly, the flow velocity of horizontal stroke cylinder portion 14 accelerates, and the foul that also can extend in this foul 30 transports distance.
And the rinse water quantitative change that does not contain foul of flowing after foul is discharged is many, so improved the drain outlet portion 4 after foul discharge, the cleaning performance of return trap socket 15.
And in the present embodiment, high bottom 16 is formed on the side (left side of Figure 10) of left and right directions of the bottom 3 of urinal face 2.Further, the opposite side (right side of Figure 10) at the left and right directions of the bottom 3 of urinal face 2 is formed with depressed part 17.Thus, with high bottom 16 be formed on left and right directions both sides situation and do not have the situation of depressed part 17 to compare, in cleaning process (3), can make the water yield of urinal 1 interior retention become many.Therefore, can in upper cleaning process (2) once, make the water yield of discharging become many, it is elongated that foul transports distance.
In addition, in present embodiment, in above-mentioned cleaning process, as mentioned above, from water supply unit 10, supply with rinse water and become swirling flow, on urinal face 2, flow and clean.In this situation, in cleaning process (2), rinse water flows along the one side of circumferentially circling round from top to bottom on one side on urinal face 2, when approaching bottom 3, as shown in the arrow P of Fig. 8, on high bottom 16 and with the bottom, side of the high bottom 16 urinal faces 2 that are connected, Yi Bian Yi Bian circle round from back to front mobile.Then, as shown in the arrow Q of Fig. 8, Fig. 9, collide face 23 with the swirling flow of protuberance 7 and collide, and so that flow and guided towards the mode of drain outlet portion 4, by depressed part 17, flow in drain outlet portion 4.That is,, by protuberance 7 (guide mechanism 6), make to be transformed to flow (the arrow Q) towards drain outlet portion 4 along circumferential flow (arrow P) of urinal face 2.
And, a part of colliding the rinse water of the top of face 23 colliding with swirling flow is guided as the side along protuberance 7 is oliquely downward towards drain outlet portion 4 sides, because the side 8 of drain outlet portion 4 sides and the medial surface 9 of drain outlet portion 4 of protuberance 7 is connected smoothly, so flowing into swimmingly, this rinse water discharges oral area 4.
On those grounds, in present embodiment, in the situation that rinse water keeps the mode of swirling flow to flow to drain outlet portion 4, can be suppressed near the turbulent flow producing drain outlet portion 4, can make rinse water flow to swimmingly drain outlet portion 4.
; in present embodiment; on the urinal face 2 below 11 in Sealing Surface; there is the mobile guide mechanism 6 (protuberance 7) towards drain outlet portion 4 that is configured to the swirling flow after colliding with swirling flow and making to collide; so can make swirling flow flow to swimmingly drain outlet portion 4, be suppressed near the turbulent flow being caused by swirling flow drain outlet portion 4.
Therefore, for example, in the situation that discharge the ight soil of dysentery shape, when be not as in the past by swirling flow towards to drain outlet portion 4 sides guidings while carrying out draining, the ight soil of dysentery shape may take advantage of swirling flow to swim in urinal 1, and in present embodiment, even the ight soil of dysentery shape also can be discharged swimmingly.Therefore, can improve with the less cleaning water yield being produced by swirling flow the discharging performance of foul.
In addition, in embodiment shown in the drawings, the guide mechanism 6 that makes to flow towards drain outlet portion 4 exemplified with being provided for colliding with the swirling flow of rinse water on urinal face 2, but guide mechanism 6 can be set on urinal face 2 yet.
And, in the above-described embodiment, exemplified with form protuberance 7 on urinal face 2, form the structure of guide mechanism 6, as guide mechanism 6, so long as be configured to the mobile parts towards drain outlet portion 4 that make swirling flow with swirling flow collision, be not limited to protuberance 7.For example, also can on urinal face 2, form guide channel, on this guide channel, be provided for making the mobile collision face towards drain outlet portion 4 with swirling flow collision.Certainly, as guide mechanism 6, can be also other modes.
And, in the above-described embodiment, by protuberance 7 (guide mechanism 6) is formed on the urinal face below Sealing Surface, so that rinse water convolution time does not hinder convolution in above-mentioned cleaning process (1), but also can project upwards and arrange from Sealing Surface.
And, in the above-described embodiment, a side (left side of Figure 10) exemplified with the left and right directions of the bottom 3 at urinal face 2 forms high bottom 16, and a side identical in the side with being formed with high bottom 16 arranges water supply unit 10, but the present invention is not limited to this structure.For example, also can form high bottom 16 in a side (left side of Figure 10) of the left and right directions of the bottom 3 of urinal face 2, on the top of the opposite side (right side of Figure 10) of the left and right directions of urinal 1, towards side (in Figure 10 towards left side) the water supply unit 10 of ejection rinse water is set.That is, also can be on the top of urinal 1, the water supply unit 10 that the mode with the circumferential ejection rinse water along urinal 1 forms is set, and high bottom 16 is formed on to the place ahead of drain outlet portion 4 on the flow direction of rinse water.
