を開弁状態に保つている。 In such a drainage device C, the drainage valve c is normally closed as shown in FIG. 4, and the level of the stored water is above the upper end of the inner weir 29. Now, if you turn the lever handle 59 counterclockwise, for example, in order to clean feces, and swing upward the end of the lever 61 connected to the operating rod 50, the drain valve body 51 is pulled up and the drain valve c opens, and the water in the tank body A passes through the upper surface openings of the inner and outer weirs 29 and 30, the passage 46, the window hole 37, the through hole 45, and the small drainage passage 44, and then drains from the drain valve c to the toilet bowl. D is discharged and the water level begins to fall. (Fig. 5) At this time, since the drainage area of the small drainage passage 44 is extremely small compared to the window hole 37 and the through hole 45, when the water level falls from the upper end of the inner weir 29, the water level in the container 43 falls at a rate of is slower than the falling speed of the water level in other parts, and the water level in the container 43 is always higher than the water level in other parts. (Figures 6 and 7) Most of the water in the tank body A is in the toilet bowl D.
Even when the water level inside the tank body A excluding the container 43 has dropped to the lower edge of the window hole 37 and the prescribed amount of water has flowed out, water still remains in the container 43.
A float 49 disposed within this container 43 is in a floating state, and is connected to the operating rod 5 via a stopper 52.
0, that is, the drain valve body 51 is prevented from descending, and the drain valve c
The valve is kept open.
従つて、水位が窓孔３７下縁まで下がつた後は

いる）により窓孔３７を乗り越えた分の水だけが
排水され続け、便器Ｄがサイホン式便器の場合に
は、この水をトラツプ部の封水として利用でき
る。 Therefore, after the water level has fallen to the lower edge of the window hole 37, water is supplied from the water supply device B (water supply from the water supply device B has started as the water level falls due to the operation of the drainage device C) to overcome the window hole 37. If toilet D is a siphon type toilet, this water can be used to seal the trap.
尚、封水量を増やす目的で、外堰３０の下方に
窓孔３７とは別に小孔を開設してもよい。 In addition, for the purpose of increasing the amount of water sealed, a small hole may be opened below the outer weir 30 separately from the window hole 37.
その後、排水小通路４４からの排水に伴う容器
４３内の水位下降によりフロート４９の位置が下
がり、それに伴つて排水弁体５１が排水弁座３１
に近づき、排水弁ｃを閉じる。 Thereafter, as the water level in the container 43 falls due to drainage from the small drainage passage 44, the position of the float 49 lowers, and accordingly, the drainage valve body 51 moves toward the drainage valve seat 31.
, and close the drain valve c.
即ち、排水弁ｃは所定水量を排水してから若干
遅れて閉弁することになり、容器４３、排水小通
路４４、フロート４９、ストツパー５２は排水装
置Ｃの遅閉手段６２を構成することになる。 That is, the drain valve c closes with a slight delay after draining a predetermined amount of water, and the container 43, small drain passage 44, float 49, and stopper 52 constitute the slow closing means 62 of the drain device C. Become.
排水弁ｃ閉弁後、容器４３内の水は更に抜け、
フロート４９は下降を続けてストツパー５２から
離れ、容器４３内の水が完全に抜け切るとフロー
ト４９は容器４３の底に当接する。 After the drain valve c is closed, the water in the container 43 is further drained,
The float 49 continues to descend and separates from the stopper 52, and when the water in the container 43 is completely drained, the float 49 comes into contact with the bottom of the container 43.

に上昇して第４図の状態に戻る。 On the other hand, as the drain valve c closes, the water level in the tank body A begins to rise (Fig. 8), and water flows in from the window hole 37 through the passage 46 between the outer weir 30 and the inner weir 29, and the through hole 45. The water level also rises in the lower space 42 of the inner weir 29, and the water flows into the container 43 through the small drainage passage 44, causing the float 49 to float up and come into contact with the stopper 52. (Fig. 9) Then, the water level rises further and returns to the state shown in Fig. 4.

内の水位が下降を始める。（第１０図）
水位が下降を続け外堰３０の上端まで下がると
排水量は所定の水量達する。 Therefore, the water in the tank body A is transferred to the inner and outer weirs 29,
It is discharged from the drain valve c through the upper surface opening 30, the passage 46, the through hole 45, and the small drainage passage 44, and is discharged from the tank body A.
The water level inside begins to fall. (Fig. 10) When the water level continues to fall and reaches the upper end of the outer weir 30, the amount of water discharged reaches a predetermined amount.
このとき容器４３内の水は未だ残つており、フ
ロート４９の浮力によりストツパー５２を介して
排水弁体５１が持ち上げられ排水弁ｃは開弁状態
に保たれている。 At this time, water still remains in the container 43, and the buoyant force of the float 49 lifts the drain valve element 51 via the stopper 52, keeping the drain valve c open.

図の状態に復帰する。 At this time, since the inner weir 29 is formed higher than the outer weir 30, no water flows into the container 43.
The water in the container 43 continues to decrease, and the drain valve body 51 continues to descend accordingly. (FIGS. 11 and 12) Then, the water in the container 43 further decreases, and accordingly, the drain valve body 51 also lowers, and the drain valve 51 closes. After that, the water in the container 43 decreases for a while, and the float 49 separates from the stopper 52. (Fig. 13) On the other hand, when the drain valve 51 is closed, water flowing over the upper end of the outer weir 30 and into the outer weir 30 causes the inner weir 2
9 is filled, and water further flows into the container 43 from the drainage small passage 44, causing the float 49 to float and come into contact with the stopper 52.
(Fig. 14) After that, when the water level inside and outside of the outer weir 30 becomes equal and the pressure inside and outside of the outer weir 30 becomes equal, and the force that presses or pulls the opening/closing plate 38 against the outer surface of the outer weir 30 is released, the opening/closing plate 38 It slides downward due to its own weight and opens the window hole 37 again. (Figure 15) The water level in tank body A continued to rise, and the water level in tank body A continued to rise.
Return to the state shown in the figure.
尚、排水装置Ｃは必ずしも上述のような大便洗
浄用と小便洗浄用とに切換える構造とする必要は
