A water pouring mechanism 26 formed as 6a is provided, and water pouring out the water in the water holding container 1 near the bottom of the water holding container 1 and forming a pouring plug 26b that can stop the pouring A mechanism 26 is provided.

A second inlet 41 connected to the water pipe 9 via the second water tap 40 is provided in the flow path mounting cap 3 provided in the third container opening 2 from the left of the water retention container 1. The second inflow path 41 is provided by opening the inside of the water retaining container 1 by attaching the inflow port portion 42 to the flow passage mounting cap 3 of the container mouth portion 2 of the water retaining container 1.

A flush valve 49 for opening and closing the second inflow passage 41 is provided in the second inflow passage 41. As shown in FIGS. 1 and 2, the flush valve 49 has a pressure accumulating chamber 50 provided in the flush valve 49 and a water pipe 9
Further, a pressure accumulation passage 51 is connected via a pressure accumulation passage opening / closing valve 48.

The pressure accumulating chamber 50 is connected to the pressure accumulating discharge path 5
2, and the discharge port 53 of the pressure accumulation discharge path 52 is attached to the flow path mounting cap 3 provided in the second container opening 2 from the right of the water retention container 1 shown in FIG. It is open.

A float valve 68 for opening and closing the discharge port 53 of the pressure accumulation discharge passage 52 is provided at the discharge port 53 by the vertical movement which is the rise and fall of the water level in the water retention container 1.
By raising the float 70 of the float valve 68, the valve 69
And the valve 69 that has been pushed up
By closing the discharge port 53 of the
The valve 69 is lowered to open the discharge port 53.

A discharge port 53 of the pressure accumulation discharge path 52
Is formed to have a smaller diameter than the inflow port portion 42 of the second inflow path 41. Then, as shown in FIG. 2, the diaphragm 61 is pulled toward the pressure accumulating chamber 50 side by the tension spring 62 as the pressure in the pressure accumulating chamber 50 decreases.
The valve rod 60 attached to the valve rod 60 and the second inflow passage opening / closing valve 59 attached to the valve rod 60 are attracted toward the pressure accumulating chamber 50, and the second inflow passage opening / closing valve 59 of the flush valve 49 is opened. The two inflow passages 41 are formed so as to open.

Then, as shown in FIG. 3, when the pressure in the pressure accumulating chamber 50 rises, the diaphragm 61 is pulled and the spring 6 is pulled.
It is formed so as to be pushed out from the pressure accumulating chamber 50 against 2, and the second inflow passage opening / closing valve 59 of the flush valve 49 is closed and the second inflow passage 41 is closed.

A check valve 32 for opening and closing the air passage 33 is provided on the flow path mounting cap 3 of the container opening 2 provided on the leftmost side of the water retention container 1, and the check valve 32 floats. The air passage 33 is closed by the floating member 34, and the air passage 33 is opened by lowering the floating member 34 by lowering the water level.

In this embodiment, when the water retaining container 1 is filled with water, the float 34 of the check valve 32 floats up, and the air passage 33 for communicating the inside of the water retaining container 1 with the outside of the water retaining container 1.
To prevent the water in the water retention container 1 from leaking to the outside from the air passage 33.

When the water container 1 is filled with water, the flush valve 49 provided in the second inflow passage 41 is closed even if the second water tap 40 is open, and the second inflow passage 41 is closed. Therefore, no water flows into the water retention container 1.

That is, when the water container 1 is filled with water, the float 70 shown in FIG. 1 and FIG.
9, the valve 69 closes the discharge port 53 of the pressure accumulation discharge path 52. In this case, if the pressure accumulation passage opening / closing valve 48 is open and the water pipe 9 is flowing, the pressure accumulation passage 51
Water flows from the pressure accumulating chamber 50.

Since the discharge port 53 of the pressure accumulation discharge passage 52 is closed as described above, the water flowing into the pressure accumulation chamber 50 pushes down the diaphragm 61 against the pulling spring 62 to open and close the second discharge passage. The valve 59 is pushed down, the second inflow path 41 is closed, and the water does not flow into the water retention container 1 from the inflow port portion 42.

When the first water tap 10 is opened in this state, the water that has passed through the first water tap 10 from the water pipe 9 flows into the upper part of the water retention container 1 through the water injection port 12. Then, the same amount of water as the inflowing water flows from the bottom of the water retention container 1 into the pouring path 19
Since this water is pushed out to the outside from the spout 20 above the water retention container 1 and flows out, this water is normally used.

Next, when the water pipe 9 is cut off, the water pouring mechanism 26 is operated to pour out the water in the water retaining container 1 for use. Then, the water level in the water container 1 drops. Then, the float 34 of the check valve 32 descends, the check valve 32 opens the air passage 33, sucks air into the water retention container 1, and smoothly discharges water from the pump device 26a and the spout plug 26b. To be done.

The pump device 26a can be used to pump water to a high place. As the float 34 of the check valve 32 descends, the float 70 of the float valve 68 also descends, and the valve 69 of the float valve 68 also opens the discharge port 53 of the pressure accumulation discharge path 52.

Then, as described above, the float valve 68
When the discharge port 53 of the pressure accumulation discharge path 52 is opened, the water in the pressure accumulation chamber 50 of the flush valve 49 flows out from the discharge port 53. Then, the tension bar 62 of the flush valve 49 bends the diaphragm 61 to draw the second inflow passage opening / closing valve 59, and the second inflow passage opening / closing valve 59 opens the second inflow passage 41.

The second water tap 40 and the accumulator opening / closing valve 4
When 8 is opened and the water level of the water retention container 1 is lowered, when the water supply to the water pipe 9 is restarted, the water flows from the second water tap 40 through the second inflow passage 41 and flows. It flows into the water retention container 1 through the inlet 42.

When the water container 1 is filled with water, the check valve 32 closes the air passage 33 and the float valve 68 closes the discharge port 53 of the pressure accumulation discharge passage 52. Then, the discharge port 53 of the pressure accumulation discharge path 52 is closed, and the pressure of the pressure accumulation chamber 50 in which water is accumulated inside causes the diaphragm 61 to move.
And the second inflow passage opening / closing valve 59 is pushed down, and the second inflow passage 4
1 is closed, and the injection of water into the water retention container 1 is automatically stopped.

The inflow port 4 of the second inflow path 41
2 may inject water into the water retention container 1 in a short time when water supply is restarted, so it is not preferable to form the second inflow path 41 and the inflow port 42 with a small diameter.

On the other hand, the discharge port 53 of the pressure accumulation discharge path 52
Since the water flows out from the pressure accumulating chamber 50 when the water is cut off, it can be formed to have a considerably small diameter. If the discharge port 53 has a small diameter, the float 70 that closes the discharge port 53 can be formed small.

Therefore, compared with the case where the inflow port portion 42 of the second inflow passage 41 as shown in FIG. 5 is opened and closed directly by the float valve 68, the accumulated pressure discharge of the flush valve 49 which opens and closes the second inflow passage 41. The float valve 68 of the present invention that opens and closes the discharge port 53 of the passage 52 can be formed in a small size, and the float valve 68 can be easily attached to the water retention container 1.

[0044]

According to the present invention, the water retention container 1 is provided with the second inflow passage 41 connected to the water pipe 9, and the second inflow passage 41 is provided with the inflow port portion 42 opened in the water retention container 1. Second
The inflow passage 41 is provided with a flush valve 49 for opening and closing the second inflow passage 41, and the pressure accumulation chamber 50 provided in the flush valve 49 is
The accumulator 50 is connected to the water pipe 9 and the accumulator 50 is connected to the accumulator discharge path 5
2 and connect the discharge port 53 of the pressure accumulation discharge path 52 to the water storage container 1
A float valve 68 that opens inwardly and opens and closes the discharge port 53 of the pressure accumulation discharge path 52 by the vertical movement of the water level in the water retention container 1 is provided. The second inflow passage opening / closing valve 59 is opened, the second inflow passage 41 is opened, and the second inflow passage opening / closing valve 59 is closed by increasing the pressure in the pressure accumulating chamber 50.
Is formed so as to close.

Therefore, according to the present invention, when the water supply is released and water is passed to the water container 1 in which the water level is lowered by using the water inside when the water is cut off, water is injected using the second inflow path 41,
Then, when the water retaining container 1 is filled with water, the flush valve 49 is operated by using the float valve 68, and the second inflow passage opening / closing valve 59 of the flush valve 49 closes the second inflow passage 41 and the inflow port The injection of water from the portion 42 into the water retention container 1 can be automatically stopped.

To open and close the second inflow path 41, the float valve 68 opens and closes the discharge port 53 of the pressure accumulation discharge path 52, opens and closes the discharge port 53 of the pressure accumulation discharge path 52, and connects to the pressure accumulation discharge path 52. The second inflow passage opening / closing valve 59 is moved by the water pressure of the water accumulated in the pressure accumulating chamber 50 to open / close the second inflow passage 41.

Therefore, according to the present invention, the float valve 68 can be formed as a small float valve 68 that only opens and closes the pressure accumulating chamber 50, and the float valve 68 can be easily attached to the water retention container 1. .
