An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show the overall structure of a water retention tank a of the present invention. One end 2 of the water retention tank a (FIG. 1)
Is formed at the water inlet 4 which is opened so that water w can flow through the home pipe 1A. on the other hand,
The other end 3 (upper in FIG. 1) of the water retention tank a is formed in a water outlet 5 which is also opened so that water w can flow out to the domestic pipe 1B in the direction of the faucet 10 (claim 1). .

The water holding tank a is formed in a portable size and shape. Specifically, the entire shape of the water retention tank a is formed in a cylindrical shape, and the vicinity of each base of the water inlet 4 and the water outlet 5 at both ends 2 and 3 is formed into curved portions 12 and 13 having a curved shape. (Claim 2).

A tank faucet 17 capable of freely discharging water w in the tank a is attached obliquely to the curved portion 12 (or the curved portion 13) of the water retention tank a (claim 3).
By attaching it obliquely to the vicinity of the base of the tank a, the water w in the water retention tank a can be flushed out.

The water holding tank a is made of lightweight stainless steel, aluminum, plastic, or the like so that anyone can easily carry it and carry it.
An embodiment formed in a compact design with 0 to 120 cm and a diameter of about 5 to 20 cm is preferred (Claim 4).

The water outlet 5 of the water holding tank a is provided with
By attaching and opening the air vent plug 11 that can be opened and closed as shown in (1), the air accumulated in the water retention tank (a) can be released freely to the outside, which is safe (claim 5).

Check valves 6 and 7 are attached to the water inlet 4 and the water outlet 5, respectively (claim 6). The specific structures of the check valves 6 and 7 are shown in FIGS. 3 and 4, respectively.

The check valve 6 for the water inlet 4 shown in FIG.
A channel 66 is formed in the hollow interior, and a ball valve body 60 is mounted in the central chamber 65 near the water main, and a coil spring 61 is mounted near the faucet 10. The outer portion is formed at a joint attaching / detaching portion 63 detachable from the one-touch type joint 8 described later, and the inner portion is formed at a tank connecting portion 64 having a thread which can be screwed into the water inlet 4 of the water retention tank a. The seat portion 62 of the ball valve body 60 in the check valve 6
Is provided at the end of the central chamber 65 near the outer joint attaching / detaching portion 63.

The check valve 7 for the water outlet 5 shown in FIG.
The basic structure is the same as that of the check valve 6. A flow path 76 is formed in the hollow interior, and in a central chamber 75, a ball valve 70 near the water main, and a coil spring 71 near the faucet 10.
Is loaded. The outer part is a one-touch joint 9 described later.
The inner part is formed at a tank connecting part 74 having a thread which can be screwed into the water outlet part 5 of the water retention tank a. On the other hand, this check valve 7
The seating portion 72 of the ball valve element 70 is provided with the check valve 6.
In contrast to this, it is provided at the end of the central chamber 75 near the inner tank connecting portion 74.

It is preferable that the inner peripheral surface 14 of the water retention tank a is applied with a germicidal coating for preventing the rot of water (claim 7).

A one-touch detachable one-touch joint 8 is connected to the joint attaching / detaching portion 63 of the check valve 6 so as to cover and cover the joint attaching / detaching portion 63, and is connected to the check valve. The same one-touch type joint 9 is also detachably connected to the joint attaching / detaching portion 73 of FIG.

Therefore, fresh water w constantly flows while being kept in the tank a by daily use of the tap water. That is, the water w flowing into the water holding tank a through the home pipe 1A is supplied as shown by an arrow in FIG. At that time, in the water retention tank a, water w flows along the inner wall surfaces of the curved portions 12 and 13 in the tank a (see the symbol k), and circulates without staying in the curved portions 12 and 13. Therefore, the water w does not stay in the tank and rot.

If necessary in an emergency such as a disaster, the water holding tank a is connected to the one-touch type joint 8,
9 is released and removed from the home pipes 1A and 1B, and the faucet 17 for the tank is twisted while holding the air vent plug 11, so that the water w in the tank a easily comes out of the faucet 17 and is immediately used as drinking water. be able to.

FIG. 5 shows a usage example of a plurality of the water retention tanks a. A plurality of the water retention tanks a are connected in a row in the middle of the home pipes 1A, 1B via hoses 15, and the water retention tanks 1a are detachably connected by the one-touch type joints 8, 9, respectively. (Claim 8). In each water holding tank a, a check valve 6 on the water inlet 4 side is disposed on the side of the domestic pipe 1A in the direction of the main water pipe, and a check valve 7 on the side of the water outlet 5 is disposed on the side of the domestic pipe 1B in the direction of the faucet 10. ing. Each of the water retention tanks a is a front and rear hose 1 as shown in the illustrated example.
5 and home pipes 1A and 1B are detachably locked to a locking member 18 fixed to the wall surface 16.

According to this embodiment, since the water w can be held in the plurality of water holding tanks a, a large amount of water w can be stored at one time.

[0031]
