Abstract

<P>PROBLEM TO BE SOLVED: To prevent any detention of dirty water at a bottom portion of the rainwater tank by extending an overflow pipe to the bottom portion of the rainwater tank. <P>SOLUTION: An overflow pipe 3 is extended to the bottom portion of the rainwater tank. In this way, any detention of dirty water in the bottom portion of rainwater tank can be prevented. That is, when the water level exceeds its high water level, any dirty water in the bottom portion of the rainwater tank can be pushed upward and drained through the overflow pipe thereby keeping rainwater clean and healthy inside the tank. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

この発明は、雨水タンクに関する。 The present invention relates to a rainwater tank.

従来の雨水タンクの構造は、図２に示すように、オーバー管３は流入管２接続部より上の位置に設置されていた。 In the conventional rainwater tank structure, as shown in FIG. 2, the over pipe 3 is installed at a position above the connection portion of the inflow pipe 2.

しかしながら、以上の技術によれば、汚泥がタンク底部につねに滞留していた、そこで、この発明は、雨水タンク底部に溜まった汚泥が、満水以上水が貯まった時オーバー管と共に排水されるため雨水タンク貯水の水は流入水と同じ水質になり衛生上よくなることを課題とする。However, according to the above technology, sludge always stays at the bottom of the tank. Therefore, the present invention is because the sludge accumulated at the bottom of the rainwater tank is drained together with the overpipe when the water is full or more. The problem is that the water stored in the tank will have the same water quality as the influent water and will be hygienic.

以上の．課題を解決するために、オーバーの配管をタンク底部付近まで延ばした配管とする特徴の、雨水タンクである。 More than. In order to solve the problem, the rainwater tank is characterized in that the piping of the over is extended to the vicinity of the bottom of the tank.

オーバー管を、雨水タンク底部まで延長したため、雨水タンク底部の汚泥は、水位が満水以上時にオーバーの雨水と一緒に押され排水される。 Since the over pipe was extended to the bottom of the rainwater tank, the sludge at the bottom of the rainwater tank is pushed and drained together with the overrain when the water level is full.

この発明の一実施形態を、図１に示す。
オーバー管３を、雨水タンク１内部の下部まで延長して配管する。One embodiment of the present invention is shown in FIG.
The over pipe 3 is extended to the lower part inside the rainwater tank 1 and piped.

「実施形態の効果」
この実施形態によれば、雨水タンク内部の上部の水よりオーバー配管の下部の滞留水が先に排水される。したがって、タンクの下部に滞留していた汚泥が先に排出されるためタンク内底部は流入水と常に同じ水質であり汚泥が滞留せず水は清潔であり衛生上よい。"Effect of embodiment"
According to this embodiment, the staying water in the lower part of the overpipe is drained before the water in the upper part inside the rainwater tank. Therefore, since the sludge staying in the lower part of the tank is discharged first, the bottom of the tank always has the same water quality as the inflowing water, the sludge does not stay and the water is clean and hygienic.

「他の実施形態」
図１の実施形態では、オーバー管３は、雨水タンク１の内部であったが、他の実施形態では、図３のオーバー管４のように、雨水タンク１の外部に設けてもよい。
図１の実施形態では、オーバー管３であったが、管でなく、図４の板５仕切ってもよい。"Other embodiments"
In the embodiment of FIG. 1, the over pipe 3 is inside the rainwater tank 1. However, in another embodiment, the over pipe 3 may be provided outside the rainwater tank 1 like the over pipe 4 of FIG. 3.
In the embodiment of FIG. 1, the over pipe 3 is used, but instead of the pipe, the plate 5 of FIG. 4 may be partitioned.
