Description

  The present invention relates to a scattering prevention device for a drainage pipe of a veranda in a cold district such as Hokkaido.

  Conventionally, drainage pipes on verandas in cold districts such as Hokkaido have been cutting the portion where drain metal fittings are raised about 300 mm from the lower end to prevent freezing. This is to prevent the drainage from the drainage pipe in the winter and the drainage hardware of the veranda and the drainage pipe are connected by ice, which may impair the drainage function.

  On the other hand, in the summer, when the floor of the veranda is washed with water on the upper floor, strong air blows into the space between the drain pipe and the drainage basin, causing water to scatter and soiling laundry that has been dried on the lower floor. In some cases, complaints may be made by residents on the lower floors.

  For preventing the scattering of water by the drainage pipe of the veranda, the cover described in Patent Document 1 is known as a countermeasure for preventing the scattering of roof drain.

JP 2001-262794 A

  However, the conventional cover for preventing scattering of the veranda is a case where the lower part of the drain pipe is close to the drain hardware, and a strainer is provided at the lower part of the drain pipe. It is not applicable to cold districts where drainage pipes are cut so that ice is not connected like the verandas in

  Therefore, as a countermeasure for preventing water splash in the summer in a cold region, there is a countermeasure using, for example, a plastic bottle 11 as shown in FIG. The bottom of the plastic bottle 11 is cut and inserted into the lower part of the drain pipe 10 cut from the bottom, and the drain pipe 10 and the plastic bottle 11 are connected by a gum tape (registered trademark) 12.

However, in this conventional method, if the forgetting to remove the PET bottle 11 from the drain pipe 10 is good in the summer but in the winter, the frozen ice may lead from the drain pipe 10 to the drain 9. Moreover, the state that the PET bottle 11 is attached to the drain pipe 10 with the gummed tape (registered trademark) is also inferior in appearance from the veranda.
The anti-scattering device for drainage pipes of a veranda according to the present invention has been proposed in order to solve such problems.
