Description

  The present invention relates to a drainage hose connection joint for draining rainwater overflowing from a rainwater storage tank to a drainage pipe together with rainwater flowing through a gutter.

  Conventionally, rainwater drained from rain gutters has been used for watering plants, garden trees, etc. or for car washing. Such use of rainwater enables water saving and contributes to environmental protection.

  As an apparatus for taking rainwater, for example, a rainwater intake apparatus described in Patent Document 1 is known.

  In the rainwater intake apparatus, a diversion box for diverting rainwater is attached to the middle part of the dredger, and a rainwater storage tank is connected to the diversion box via an intake pipe. Part of the rainwater flowing from the roof through the fence is diverted through the diversion box, and is collected in the rainwater storage tank through the intake pipe. The remaining rainwater passes through the diversion box and is then drained directly into the drain.

  Moreover, in the said rainwater intake device, the overflow pipe is connected to the upper end part of the rainwater storage tank in the one end. The other end of the overflow pipe can be led to the drainage ditch, and when the rainwater storage tank is full, the rainwater overflows from the rainwater storage tank and drains to the drainage ditch via the overflow pipe.

The overflow pipe can also be connected to the trough using a trifurcated pipe, and the overflowing rainwater can be drained into the drain after draining into the trough.
JP-A-8-85982
