Abstract

PROBLEM TO BE SOLVED: To obtain an emergency water storage tank, in which fresh water is stored at all times and which requires no cleaning, by folding back a pipe having a bore larger than a water service pipe or spirally disposing the pipe on its midway to the water service pipe laid in a site. SOLUTION: A circular or polygonal pipe or hose having a bore larger than a current water service pipe is folded back in arbitrary length or arranged spirally on its midway to the water service pipe laid in a site, and the pipes are superposed at a single stage or a plurality of stages and an emergency water storage tank 1 is formed. An air vent 4 and a check valve 2 are installed on the water service main-pipe inlet 5 side of the water storage tank 1, a pump 3 is mounted on a faucet-side outlet 6, and the back flow of water in the water storage tank 1 is prevented while the water can be discharged from the faucet- side outlet 6 when a water service main pipe is broken and the supply of water is stopped. Since water in the water storage tank 1 is flowed towards the faucet- side outlet 6 from the water service main-pipe inlet 5 side, it is fresh at all times and is not brought into contact with air containing various germs, thus preventing putrefaction. Since dust and foreign matters are not entered, the inside of the tank 1 need not be cleaned.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency water storage tank.

[0002]

2. Description of the Related Art In the prior art, water was stored in a container or a water receiving tank.

[0003]

The conventional tanks and containers are rotted due to algae, bacteria and the like. Therefore, the water must be changed regularly and the tank must be cleaned. Therefore, there is a technical problem for eliminating the need to clean the tank by eliminating the regular water exchange, and the present invention is
An object is to solve the problem.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been proposed in order to achieve the above-mentioned object, and a circular pipe having a diameter larger than that of the existing water pipe and a multi-diameter pipe are provided in the middle of the laid water pipe. A method of folding a rectangular pipe or hose into an arbitrary length, or arranging it in a spiral and stacking it in a single step or in multiple steps, tap water goes from the main inlet side of the water pipe to the outlet side of the faucet. Thus, the emergency water storage tank is provided so as to flow in one direction (direct current).

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, every time tap water is used, the water passes through the tank pipe connected in series from the inlet on the main side of the water pipe, flows toward the faucet side, and the water constantly moves,
Since the water does not come into contact with the air containing various bacteria, it can prevent the water from spoiling and can always store new water, and the pipe itself is sealed so that dust and foreign substances are difficult to enter.

At home, under the floor, etc. In a building or hospital, it does not take up space by installing it on the rooftop. In addition, on the rooftop, by arranging them evenly and laying low, the stability is good, and a structure that does not generate a concentrated load on the building like a tank does not affect the building.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 shows a tank when installed in a home. PVC pipes are arranged side by side and the pipes are connected in series. Figure 2 shows a water storage tank installed on the roof of a building or hospital. This water storage tank has a shape that is not arranged in a spiral shape along the periphery of the roof. (2) of FIG. 2 is a check valve, because the water in the water storage tank does not flow backward when the water pipe is broken and the water is cut off.

The present invention can be improved in various ways without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.

[0009]

As described in detail in the above-mentioned one embodiment, the present invention provides the emergency water storage tank of the present invention under the floor of a home or on the roof of a building or a hospital so that it does not take up a lot of space and is always available. You can refill it with fresh water and not have to clean the inside of the tank.
