Description

[Detailed Description of the Invention] The present invention relates to a flushing water supply device from a separately installed flushing water tank of a simple flush toilet that flushes excreta with a very small amount of water. In simple flush toilets in which the flush water tank is attached directly to the toilet bowl, the distance from the water tank to the flush water outlet is short, so after the water tank drain valve is closed, water with no flow flows into the excretion bowl, so-called dead water. The amount of water is very small, so it is not a problem, but if the flush water tank is installed in a corner of the toilet, away from the toilet bowl, the distance from the water tank's drain valve to the toilet bowl will be longer. ,
After closing the drain valve, pipe from the drain valve to the toilet bowl,
In other words, the amount of water in the drain pipe increases, and the amount of dead water increases. This invention prevents the wash water in the piping from being discharged after the drain valve is closed.
This is a flush water supply device that aims to make it possible to save water in the same way as a simple flush toilet with a water tank even in a simple flush toilet with a remotely installed flush water tank. explain.

Figure 1 is an overall cross-sectional view of a simple flush toilet and flush water tank using an embodiment of the flush water supply device according to the present invention. Up to toilet bowl 2, drain pipe 3
The distal end of the drain pipe 3 inside the toilet bowl is provided above the excretion bowl 4 of the toilet bowl 2, and the spout 5
The water receiver 7 is water-tightly passed through the sealing plate 6 of the water receiver 7, which has an upper surface sealed 6, and is opened 8 into the container 7. Inside the water receiver 7, a water retention section 10 is provided below the outer wall of the container, that is, on the opposite side of the spout 5, and is partitioned by a weir wall 9 that is lower in height than the outer wall. , the opening 8 of the drain pipe 3 is connected to the water retention section 10.
It is made to become within. 11 is a drain valve that opens and closes the upper opening of the drain pipe 3 at the bottom of the water tank 1; 12 is a drain valve that opens and closes the upper opening of the drain pipe 3 at the bottom of the water receiver 7, directly above the excretion ball 4; 13 is a swinging water-sealing dish that seals the discharge port of the excretion bowl 4.

In this way, when the drain valve 11 (in the water tank 1) is opened, the cleaning water flows out through the water receiver 7 and out of the spout 5. Then, the main stream flows down while going around the upper part of the excretion ball 4 and washes the front surface of the excretion ball, and a part of the water jetting out from the drainage hole 12 washes the rear surface of the excretion ball as described above. Next, when the drain valve 11 is closed, the water outside the water reservoir section 10 in the water receiver 7 flows out from the spout 5, but the water in the drain pipe 3 flows out from the water reservoir section 1 through the opening 8 of the drain pipe.
Since it is within 0, it will not flow down.

FIG. 2 is an enlarged cross-sectional view showing only the connecting portion between the drain pipe and the water receiver in another embodiment, in which the drain pipe 3 is passed through the side wall 14 of the water receiver 7 to the water reservoir 10.
In this case as well, the drain pipe 3 is watertightly attached to the side wall 14, so that its operation and function are exactly the same as in the above embodiment.

As described above, according to the device according to the present invention, after the drain valve is closed, only water other than the water retention part 10 of the water receiver 7 flows into the excretion bowl, and no water in the pipes flows down. Since there is no water pressure, the amount of dead water can be greatly reduced.
