[Technical field to which the invention belongs]

 This invention relates to a tank for storing drinking water, which is mainly used for water supply during the drought period.

[0002]

[Prior art]

 In general, polyethylene tanks are used for hourly water supply, but the capacity is small. Also, since there is no faucet, the tank must be lifted one by one, making it difficult for women and children to use. In addition, hourly water supply generally lasts from the evening to the next morning, and in general households, it is usually the same as at-home time.However, in small business establishments and small restaurants, etc. The working hours may not be the same, and in such a case, it is not possible to draw water into the above-mentioned portable tank.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention sufficiently responds to the above-mentioned hourly water supply, and it is not necessary to have a person nearby to start water supply and to manage the tank when it is full. The issue is to provide a market with a tank that can automatically supply water during business hours, even for large-scale restaurants. Another objective is to provide a tank that prevents rainwater and other sewage from entering the tank even outdoors without a roof. Another object of the present invention is to provide a tank on the market where the lid cannot be opened unnecessarily, foreign matter is prevented from entering, and insects and slugs do not enter through the overflow tube.

[0004] Still another problem is that the tank, the lid and the faucet are generally made of a synthetic resin molded product so that erosion is reduced and no excessive force is applied to the mounting portion between the tank and the valve. is there.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned task, the present invention has a vertical axis, an open upper end of a cylindrical tank, and the opening has an outwardly protruding lip. A disc-shaped lid is provided at the opening so as to be openable and closable, and a downwardly facing lid edge of the lid is shaped to fit outside the rim of the tank, and a lower portion of a side wall of the tank is made of synthetic resin. A discharge faucet is provided, an overflow pipe and a water supply pipe are provided at the upper part of the side wall of the tank, and a synthetic resin float valve is provided at the inner end of the tank of the water supply pipe. A distinctive water storage tank.

In order to achieve the above object, the overflow pipe of the water storage tank protrudes outside the tank and is bent downward, and a part of the overflow pipe or a separate cylindrical body detachably provided on the part. It is preferable that a filter is provided in the device.

[0007] In order to achieve the above object, the present invention provides a water storage tank in which a lid is fitted to the rim of the tank and covers the upper surface of the lid and the lower surface of the rim of the tank. A gutter-shaped tightening band having a semicircular arc cross-section covering substantially the entire periphery of the rim, and a buckle portion formed with a lock engaging portion for fixing the tightening band in a tightened state. In some cases.

[0008] In the device according to the first aspect of the present invention, since the water supply faucet and the water supply pipe are connected by a water supply hose and the water supply faucet is opened, the water supply is provided. Water can be injected into the tank, and even if water is cut off when the faucet is opened, tap water will be injected into the tank in the same way as long as water supply starts, and the water level will rise even if left as it is Then, even if the float valve rises and the water tap is not closed, the float valve automatically closes and the tap water is not wasted. Even if the tap water is too high for some reason, more water will be drained from the overflow pipe and the tank will not overflow. When the water in the tank is used, the tap can be used in the same way as a normal water supply by opening the discharge faucet at the bottom of the tank. At this time, as the water level in the tank decreases, the pressure in the tank is reduced, and the outside air is sucked from the overflow pipe, so that the pressure in the tank is equal to that of the outside air.

In the invention according to claim 2, the filter is provided as described above in addition to the function described in claim 1, except that the filter is provided on the overflow tube or the cylinder connected thereto. Therefore, in normal times, insects such as slickers and ants do not invade from the over-flow tube, and since the over-flow tube is bent downward, rainwater or the like can be seen. It works to prevent the ingress of water and dust other than tap water. Further, dust and the like contained in the outside air at the time of suction of the outside air when water is discharged from the discharge faucet are blocked by the filter.

[0010] In the device of the third aspect of the present invention, since the configuration is as described above, in addition to the operation of the first or the second aspect, the tank lid can be tightened in a closed state and can be locked in that state by a lock. The lid is not opened by a third party, and the lid is not opened by strong wind, etc., and the water in the tank serves as drinking water for one to three days to maintain the water quality. .
