Description

[Detailed Description of the Invention] The present invention relates to a connector for supplying and draining water to a water storage tank in which drinking water is stored in an ordinary household in case of an emergency such as a disaster.

Recently, drinking water has been stored in a water storage tank in preparation for emergencies such as disasters, and when water is poured from the tap, the water stored in the tank is automatically replaced with newly poured water. An emergency water storage tank has been proposed that is drained and always stores fresh water.

However, even if you know that the water in the water storage tank is fresh, there are cases where freshly drawn cold water is required as drinking water, and in that case, connect the water faucet to the water storage tank. There are inconveniences such as having to remove the water hose from the water faucet each time, and problems such as the fact that the water storage tank must always be installed at a lower position than the water faucet to prevent backflow to the water supply. was there.

In view of these points, the present invention allows water from a tap to be stored in a water storage tank and drained from the tank, allowing the drained water to be used for the desired purpose. The purpose of the present invention is to provide a connector for supplying and draining water to a disaster emergency water storage tank, which allows the water storage tank to be used directly as needed, and also allows the water storage tank to be installed above the water faucet. shall be.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional side view of the water supply and drainage connector of the present invention, in which a connecting pipe portion 2 connected to a water faucet is integrally formed in the upper part of the connector body 1, and a cylindrical drain port is formed in the lower part. A water supply cylinder part 4 and a drain cylinder part 5 are provided on the sides thereof and are arranged concentrically with each other.

A cylindrical rubber gasket 6 is inserted into the connecting tube portion 2, and the top end flange portion 6a of the rubber gasket 6 is screwed onto the top end surface of the connecting tube portion 2 and the outer periphery of the connecting tube portion 2. The connector body 1 is held by a nut γ, and by press-fitting the tip of the water faucet into the rubber gasket 6, the connector body 1 can be fixedly attached to the water faucet.

Further, a t
A water supply cylinder part 4 is disposed concentrically within the drainage cylinder part 5.

On the other hand, a valve seat 8 is provided in the connector body 1 in a communication path between the connecting pipe section 2, the drain port section 3, and the water supply cylinder section 4, and a spherical three-way switching valve is mounted on the valve seat 8. 9 are arranged.

The three-way switching valve 9 can be rotated by a switching operation shaft 10 protruding outward from the connector main body 1, and in the first position of the three-way switching valve 9 (the position shown in FIG. 1), the connecting pipe portion 2 and the water supply tube part 4 are in communication with each other, and in the second position, the connecting pipe part 2 and the drain port part 3 are in direct communication with each other.

Further, the annular passage 11 formed by the water supply tube section 4 and the drain tube section 5 is configured to communicate only with the drain port section 3, and a foam net 12 is attached to the drain port section 3 as needed. is removably attached by a mounting plug 13.

Furthermore, inside the water supply cylinder part 4, from the connection pipe part 2 to the water supply cylinder part 4.
A non-return valve 14 is provided to allow water to flow inward.

In addition, the code|symbol 15 in the figure is a hose attachment metal fitting.

By the way, the hose 11 that connects the emergency water storage tank 16 (FIG. 2) and the water supply/drainage connector is composed of a single flexible inner and outer double pipe, and the water supply pipe section 18, which is the inner pipe, is As shown in FIG. 2, it is extended and inserted to the bottom of the water storage tank 16, and the drain pipe section 19, which is an outer pipe, is attached to the connection plug section 20 of the water storage tank 16 and opened into the water storage tank 16.

On the other hand, the water supply pipe part 1B of the hose 1γ is fitted into the water supply cylinder part 4 of the connector, and the drain pipe part 19 is fitted into the drain cylinder part 5 and fixed by a hose fitting 15.

Therefore, when the switching valve 9 is placed in a state where the connecting pipe section 2 and the water supply cylinder section 4 are opened and the valve of the water faucet is opened, the water flowing out from the faucet is transferred to the connecting pipe section 2, the switching valve 9, and the water supply cylinder section. 4
and the water storage tank 16 via the water supply pipe part 18 of the hose 1γ.
Accordingly, the water in the water storage tank 16 flows out from the drain port 3 through the drain pipe section 19, the passage between the drain tube section 5 and the water supply tube section 4, and is used for the desired purpose. .

On the other hand, when water from a faucet is used directly for drinking water, etc., by rotating the switching valve 9 and communicating the connecting pipe section 2 and the drain port section 3, the water flowing out from the faucet can be directly used. It flows out from the drain port 3 and can be used as drinking water or the like.

Furthermore, if the water storage tank 16 is placed at a higher position than the water faucet as shown in FIG. , the water in the water storage tank 16 will not leak out.

Further, in an emergency or the like, by removing the hose 1γ from the water storage tank 16, the water storage tank 16 can be freely carried and the water in the water storage tank can be used as drinking water or the like.

In addition, in the above embodiment, the water supply tube part and the drain tube part are shown as being concentric, but they do not necessarily have to be concentric, and it is sufficient that they have two pipes. Of course.

As explained above, in this invention, a switchable valve is installed in the water supply and drainage connector, so that you can connect the hose to the water tank to the water faucet and use the water once stored in the water tank. Use water directly from the faucet or
It can be freely selected, and usually fresh water can be stored in the water tank by using water that has passed through the water tank.

Moreover, since the water supply cylinder is equipped with a backflow prevention valve,
You can also place the water storage tank above the water faucet.
This has the advantage that there are no restrictions on the installation location.
