It is formed so as to fit between S1 and a virtual surface S2 depending from the rear end 12 of the eaves bowl 1. In the present embodiment, the water reservoir 2 is contained between a virtual surface S3 hanging from the front end of the bottom wall 13 of the eaves bowl 1 and a virtual surface S2 hanging from the rear end 12 of the eaves bowl 1. Yes.

  As described above, the rain gutter structure of the present embodiment in which the components are formed is assembled as follows, for example.

  First, the drain hole 10 is opened at a suitable place in the left-right direction of the bottom wall 13 of the eaves wall 1. Next, the lid portion 22 of the water reservoir 2 is disposed below the drain hole 10, and the drain hole 10 and the opening 20 of the lid portion 22 are communicated so as to coincide with each other in plan view. Next, the fixing portion 25 of the fixture 23 is inserted into the drain hole 10 and the opening 20 from above, and the fixing portion 25 is fixed to the cylindrical portion 24 of the lid portion 22. At this time, an adhesive is applied to fix the fixing portion 25 and the cylindrical portion 24 to prevent water leakage from between the fixing portion 25 and the cylindrical portion 24. Next, the water reservoir 2 is inserted into the lid portion 22 from below and fixed. Next, the external drainage cylinder 3 is connected to the connection hole 21 at the bottom of the water reservoir 2 so as to communicate therewith. Finally, the net-like fallen leaf guard 5 is installed above the fixture 23.

  In the rain gutter structure of the present embodiment assembled as described above, rain water is drained as follows when it rains.

  First, rainwater flows along the roof into the eaves 1. The rainwater that has flowed into the eaves 1 flows into the fallen leaf stopper 27 fixed to the drain hole 10, and then flows into the water reservoir 2 through the tubular portion 24. At this time, fallen leaves can be prevented from flowing into the water reservoir 2 by the fallen leaf stopper 27 and the net-like fallen leaf guard 5 provided around the fallen leaf stopper 27. Next, rainwater that has flowed into the water reservoir 2 gradually accumulates in the water reservoir 2 while partially flowing into the external drainage cylinder 3 through the connection hole 21. When rainwater accumulates in the water reservoir 2 and the connection hole 21 is always immersed in rainwater, the flow path in the drain tube 3 connected to the connection hole 21 becomes full. Then, since the downstream end of the drain tube 3 is connected to the ground part (such as a sewer pipe provided in the ground), a siphon phenomenon occurs, and the rainwater in the water reservoir 2 is pulled toward the drain tube 3 side. It will be in the state to be. Then, the rainwater in the water reservoir 2 is drained vigorously through the drain tube 3.

  Here, in the rain gutter structure of the present embodiment, the eaves 1 and the drain tube 3 are connected via the water reservoir 2. Therefore, compared with the case where the drain tube 3 is directly connected to the eaves rod 1, the drain tube 3 can be provided with a smaller diameter after the drain hole 10 having an opening width as large as possible is provided in the eave rod 1. Therefore, after increasing the amount of inflow into the water reservoir 2, the flow path of the drain tube 3 can be narrowed to easily cause a siphon phenomenon. Moreover, by providing the water reservoir 2 between the eaves 1 and the drain tube 3, the connection hole 21 provided in the bottom of the water reservoir 2 can be kept in a state immersed in water as much as possible. It can suppress that air is suck | inhaled into the pipe | tube 3 and the siphon phenomenon of the drain pipe 3 will be interrupted | blocked.

  As described above, the rain gutter structure of the present embodiment can stably cause the siphon phenomenon and improve the drainage performance. Therefore, in the rain gutter structure of this embodiment, the number of the drain cylinders 3 connected to the eaves 1 can be reduced, for example. Moreover, since a thin thing can be used as the drain pipe 3 connected to this eaves bowl 1, it looks good.

  In summary, in the rain gutter structure of the present embodiment, the water reservoir 2 having an opening 20 communicating with the drain hole 10 is connected to the eaves 1 having the drain hole 10. In the lower part, a connection hole 21 connected to the external drainage cylinder 3 is provided. A water reservoir container 2 is provided between a surface that hangs down from the front end of the eaves bowl 1 and a surface that hangs down from the rear end of the eaves bowl 1.

  As described above, the rain gutter structure of the present embodiment can be provided by providing the drain hole 10 at a suitable location of the single eaves 1 and connecting the water reservoir 2 to the drain hole 10. That is, since the rain gutter structure of this embodiment does not need to be attached between the end portions of the two eaves as in the conventional example, the attachment position can be freely selected. In addition, since the rain gutter structure of the present embodiment can be provided in one eave ridge 1, it has a good appearance that does not block the appearance continuity of the eave ridge 1.

  Further, the water reservoir 2 connected to the eaves bowl 1 is provided so as to fit between the front end and the rear end of the eaves bowl 1. In other words, the rain gutter structure of the present embodiment is such that the water reservoir 2 is not projected forward from the front end of the eaves bowl 1 as in the conventional example, but is projected from the rear end of the eave bowl 1 to the rear side. Because there is no, it is compact in the front-rear direction.

  Further, by providing the water reservoir 2 in communication with the drain hole 10 of the eaves bowl 1, the drainage from the eaves bowl 1 can be temporarily stored in the water reservoir 2. Therefore, since a large amount of rain water can flow from the water reservoir 2 to the external drain tube 3 at once via the connection hole 21, the drain channel in the drain tube 3 is filled with water. It becomes easy to generate a siphon phenomenon in which the drainage inside is pulled toward the drain tube 3 side. Further, since the connection hole 21 provided at the bottom of the water reservoir 2 is likely to be entirely immersed in rainwater, it is possible to prevent air from being sucked into the drain tube 3 through the connection hole 21. Therefore, the siphon phenomenon can be prevented from being blocked by air suction. Therefore, since the siphon phenomenon can be generated stably, the drainage performance is greatly improved.

  As described above, the rain gutter structure of the present embodiment can be provided at an arbitrary location of the eaves cage 1, is compact and good in appearance, and can improve drainage performance.

  Moreover, the rain gutter structure of this embodiment provides the maximum opening area inside the water reservoir 2 larger than the opening area of the drain hole 10 of the eaves 1, and the opening area of the connection hole 21 of the eaves 1. It is provided smaller than the opening area of the drain hole 10.

  As described above, the rain gutter structure of the present embodiment is provided so that the maximum opening area inside the water reservoir 2> the opening area of the drain hole 10 of the eaves 1> the opening area of the connection hole 21. . Therefore, the amount of inflow into the sump container 2 is larger than the amount of outflow from the sump container 2, and the capacity of the sump container 2 is larger than the amount of drainage of the eaves bowl 1. It can be once reliably stored in the storage container 2. Therefore, since a large amount of rain water can flow from the water reservoir 2 to the external drain tube 3 at once via the connection hole 21, the drain channel in the drain tube 3 is filled with water. It is possible to stably generate a siphon phenomenon in which the internal drainage is pulled toward the drain tube 3 side. Further, since the connection hole 21 provided at the bottom of the water reservoir 2 is likely to be entirely immersed in rainwater, it is possible to prevent air from being sucked into the drain tube 3 through the connection hole 21. Therefore, the siphon phenomenon can be prevented from being blocked by air suction. Therefore, since the siphon phenomenon can be generated stably, the drainage performance is greatly improved.

  As described above, the rain gutter structure of the present embodiment can generate the siphon phenomenon more stably and improve the drainage performance.

  Although the present invention has been described based on the embodiments shown in the accompanying drawings, the present invention is not limited to the above-described embodiments, and appropriate design changes can be made within the intended scope of the present invention. Is possible.
