SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a water collecting basin at the bottom of an eave gutter in a water collecting basin connecting a roof eave gutter and a vertical gutter for draining rainwater. The hollow pipe is passed through so that it becomes concentric, the upper end of the hollow pipe is made lower than the upper end of the eaves gutter, and the gap formed between the hollow pipe and the collecting pipe is closed with a net. At the lower part, the upper end is provided with a funnel-shaped wide-mouthed rainwater receiver having a diameter larger than that of the water collecting pipe, and a receiving member protruding from the inner side surface of the rain water receiving vessel toward the inner center. Support the lower end of each of the above, provide an overflow port between the upper end of the rainwater receiver and the water collection pipe, communicate the lower end of the rainwater receiver to the downspout,
If the amount of water collected from the eaves gutter exceeds the amount of drainage from the gutter, and the drainage from the gutter cannot be made in time, rainwater overflows from the overflow port.

[0006]

[Action] Rainwater that has flowed down from the roof is collected by an eaves gutter constructed with a slope below the eaves, flows from above the water to below the water, and flows into the catchment basin from the eaves gutter outlet. In normal rainfall, rainwater flows down into a funnel-shaped rainwater receiver from a gap between the collecting pipe and the hollow pipe, which is covered with a wire mesh for dust removal, and is then drained by a downspout. At this time, the leaves and other garbage that has been washed away with the rainwater are held down by a wire mesh stretched to prevent garbage and do not block the downspout. If the amount of drainage from the wire mesh cannot be met due to increased rainfall or garbage collecting on the wire mesh for dust removal, the water level of the eaves gutter rises, but the hollow pipe must be set lower than the side of the eaves gutter in advance. If the water level exceeds the height of the hollow pipe before reaching the height of the side of the eaves gutter, rainwater flows directly down the hollow pipe and is drained from the downspout. Furthermore, when the amount of water collected from the eaves gutter exceeds the drainage of the downspout due to the remarkable increase in precipitation and various adverse conditions, etc., the drainage from the downspout cannot be made in time. Rainwater overflows from the overflow outlet between the upper end of the wide mouth and the downfall along the outer surface of the downspout.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The water collecting basin of the present invention is provided at the bottom of the eaves gutter 1 at the bottom of the eaves gutter 1 so that the rainwater received by the eaves gutter 1 flows through the downspout 7. Are manufactured in advance with various diameters, and a diameter suitable for the diameter of the outlet of the eaves gutter can be appropriately selected. The cross section of the eaves gutter 1 of the present embodiment is formed in a square shape with an opening on the upper side. The water collecting pipe 2 is formed in a cylindrical shape having a diameter larger than the diameter of the pipe of the downspout 7, and the water collecting pipe 2 is attached so as to protrude downward in accordance with a drop opening previously opened on the bottom of the square eaves gutter 1. . In the center of the water collecting pipe 2, a cylindrical hollow pipe 3 having substantially the same diameter as the downspout 7 is penetrated so as to be concentric with the water collecting pipe 2. A wire mesh 4 for dust removal is provided in a ring-shaped gap between the hollow pipe 3 and the water collecting pipe 2 so that dust flowing along with the eaves gutter 1 along with rainwater can be held here. The height of the hollow pipe 3 is set to be slightly lower than the depth of the rectangular eaves gutter at the time of construction. Further, the lower end of the hollow pipe 3 has the same length as the lower end of the water collecting pipe 2, and the lower ends of the water collecting pipe 2 and the hollow pipe 3 are connected to and supported by a receiving member 6 described later. I have.

[0008] The rainwater receiver 5 is formed in a funnel shape, the upper end opening of which is larger than the diameter of the water collecting pipe 2, and the lower end thereof is formed with a small diameter and fitted into the upper end of the downspout 7. In addition, a ring-shaped overflow port 8 is formed between the upper end of the rainwater receiver 5 and the water collecting pipe 2, and when the amount of water from the eaves gutter 1 exceeds the amount of drainage from the vertical gutter 7, FIG.
