である。2. Description of the Related Art Conventionally, this type of water storage tank is a box-shaped tank 20, as shown in FIG. The opening / closing control valve 23 having the floating tap 22 always keeps a fixed amount, and water is supplied to the downstream side via a pump 26 by a pipe 25 from an intake port arranged slightly above the sediment 24 at the bottom. . 27 is a drain valve.
【０００３】この貯水槽は、長期間にわたる清掃を怠る
と、水道水中に含まれる僅かな錆びやタンク２０自体の

となるから、一定容量以上のものについては、一定期間
毎に清掃をすることが義務付けられている。If the water tank is neglected to be cleaned for a long period of time, a little rust contained in tap water, rust of the tank 20 itself, etc. will be generated and settled on the inner bottom, resulting in an unsanitary condition. It is obliged to clean items with a capacity greater than a certain period.
【０００４】この清掃は、タンク２０の上部に開設した
マンホール２８からタンク２０内に清掃作業員が出入り
してブラシその他で清掃する手作業によっている。[0004] This cleaning is performed by a manual operation in which a cleaning worker enters and exits the tank 20 through a manhole 28 opened above the tank 20 and cleans it with a brush or the like.

こともあって、貯溜した水を無駄に捨てなければならな
いこともある。However, entry and exit of a person in the tank is performed in a completely sanitary condition, no matter how the cleaning worker wears clean work clothes or rubber boots. It is hard to say. This cleaning is best performed when the water level in the tank 20 is lowered by closing the on-off control valve. However, for various reasons, it may be necessary to perform the cleaning when the water level in the tank 20 is high. In some cases, the stored water must be discarded.

好ましくない。Further, in the conventional tank 20, the pipe 25 is disposed slightly higher than the sediment 24, so that the lower water from the pipe 25 becomes so-called dead water and becomes drain water.
As long as 7 is not opened, it stays in the tank 20 and is not hygienic.
【０００７】そこで、この発明は、清掃作業員がタンク

た。In order to achieve the above object, a water storage tank according to the present invention has an inner bottom portion having a substantially conical downward slope, and a water supply pipe connected to the center of the water storage tank. Connect a pump and a branch pipe on the downstream side,
The branch pipe was introduced into the tank and opened inside.

す。[Function] When water is stored in the tank, sediment etc. always descends along the inner bottom part by its own weight and is sucked into the water supply pipe, and when the stored water is discharged from the tank via the pump, the water flow The sediment descends along the inner bottom and is sucked into the water supply pipe.In addition, a part of the water returns to the tank from the branch pipe and discharges water from the opening to form a cone-shaped vortex of the stored water. Then, the sediment and the like are forcibly washed away by the vortex.

In FIG. 1, a tank 1 is a cylindrical body or a polygonal cylindrical body, an inner bottom 2 of which is a substantially conical shape formed with a downward slope toward a center, and an upper part having an air vent pipe 3 and being closed. I have. A water supply pipe 4 is connected to the center of the inner bottom 2, and a pump 6 is provided in the water supply pipe 4.

る。A drain valve 5 is provided on the water supply pipe 4 on the upstream side of the pump 6, and a branch pipe 7 is connected to the water supply pipe 4 on the downstream side. A strainer 8 and an electromagnetic valve 9 are interposed in the branch pipe 7. Then, the branch pipe 7 is introduced into the tank 1, and its end is opened as a nozzle 10 near the inner bottom 2, and the inner bottom 2 is opened.
Are arranged so that a vortex can be formed around the water supply pipe 4.
【００１３】ストレーナー８は、水道水が清浄なもので
あるから、図２に示すように、必ずしも設けることはな
いが、タンク１自体の錆びその他が再びタンク１に還流
することを防止するために設けられる。Since the tap water is clean, the strainer 8 is not necessarily provided as shown in FIG. 2, but is used to prevent rust and the like of the tank 1 itself from returning to the tank 1 again. Provided.
【００１４】電磁開閉弁９はストレーナー８と対として
同様で、必ずしも設ける必要性はないが、必要時以外は
無駄であるから、必要な時だけ作動するようにする。す
なわち、内底部２に多くの錆び等が沈殿して自然排出さ
れない場合に作動させるようにしてある。The electromagnetic switching valve 9 is the same as the pair with the strainer 8, and it is not always necessary to provide it. However, since it is useless except when necessary, it is operated only when necessary. That is, it is operated when a large amount of rust or the like precipitates on the inner bottom portion 2 and is not naturally discharged.

けでもよい。The nozzles 10 are for rotating the water in the tank 1. As shown in FIG. 3, a plurality of nozzles 10 are provided at positions diametrically opposed to an annular pipe 14 communicating with the branch pipe 7. It may be provided so as to be inclined toward the rotation direction, or only one nozzle 10 may be provided as shown in FIG.

蔵されるようにしてある。A water pipe 1 is provided near the ceiling of the tank 1.
2 is introduced inside, and a fixed amount of tap water is always stored in the tank 1 via the opening / closing control valve 11 such as the floating tap 13.
【００１７】図２に示す他の実施例は、枝管６からスト
レーナー８及び電磁開閉弁９を除去してタンク１内に常
に渦流を形成するようにしたものである。In another embodiment shown in FIG. 2, the strainer 8 and the solenoid on-off valve 9 are removed from the branch pipe 6 so that a vortex is always formed in the tank 1.

２に沿って転動し、給水管４に落下する。したがって、
適時にドレンバルブ５を開くと外部へ排出できる。Then, when tap water is supplied from the water pipe 12 into the tank 1 and the opening / closing control valve 11 is operated to store a fixed amount of water in the tank 1, the sediment is deposited on the inner bottom 2 in a still water state. It rolls along and falls into the water supply pipe 4. Therefore,
When the drain valve 5 is opened at an appropriate time, it can be discharged to the outside.

プ６を駆動することにより、内底部２の中央部から給水
管４内に水が吸い込まれて下流側へ移動するとき、沈殿
物等は内底部２に沿って給水管に強制的に吸い込まれ
る。When water is sucked into the water supply pipe 4 from the central portion of the inner bottom portion 2 and moved downstream by driving the pump 6 to supply water from the tank 1, sediments and the like are removed from the inner bottom portion. It is forcibly sucked into the water pipe along line 2.
【００２０】しかし、内底部２を滑落せず、給水管４に

れるコーン状の渦巻きを作る。The water in the tank 1 forms a circulating water flow centered on the water supply pipe 4 at the center of the inner bottom portion 2 by the water flow spouting from the nozzle 10 in a certain direction. create.
【００２２】したがって、内底部２に沈殿した錆びその
他は、水流により内底部２を強制的に滑り移動して給水
管４内に吸い込まれ、下流側へと移動する。Therefore, the rust and the like settled on the inner bottom portion 2 are forcibly slid and moved on the inner bottom portion 2 by the water flow, are sucked into the water supply pipe 4, and move downstream.
【００２３】また、コーン形の渦流により、タンク１内
の水面に浮いている物体等も渦流に巻き込まれて給水管
に吸い込まれる。したがって、タンク１内は常に自動的
に洗浄される。Further, the object floating on the water surface in the tank 1 is also drawn into the vortex by the cone-shaped vortex and is sucked into the water supply pipe. Therefore, the inside of the tank 1 is always automatically cleaned.
【００２４】しかして、図２に示す例では、給水中は常

が清掃される。Thus, in the example shown in FIG. 2, a vortex is always generated during the supply of water, and the above-described cleaning action is always generated to clean the inside of the tank 1.

とが必要であることはいうまでもない。Since the strainer 8 has the inconvenience of having to be replaced or washed at regular intervals, a commercially available water purifier having a long-term filtration effect may be used to solve the inconvenience. In addition, the water storage tank has an elevated water tank such as a rooftop to which a water pipe is not directly connected, and since the elevated water tank does not usually include the pump 6 in the water supply pipe 4, the present invention is applied to the elevated water tank. Of course, it is needless to say that it is necessary to provide the pump 6.

ある。According to the present invention described above, when water is stored in the tank, the sediment or the like always descends along the inner bottom by its own weight, is sucked into the water supply pipe, and is stored through the pump. When the water is drained from the tank, the sediment etc. descends along the inner bottom by the flow of water and is sucked into the water supply pipe, and some water returns to the tank from the branch pipe and discharges water from the opening. A vortex of the stored water forms a vortex, and the vortex causes the sediment, etc., to be forcibly washed away. To keep the inside of the tank clean at all times. Therefore, there is no danger of dead water, and the tank can be cleaned without a cleaning worker coming in and out of the tank, which is extremely sanitary.
