It is being extended. A through hole 3 is provided at the lower end of the cover 36 for draining condensed water flowing down from the water guide plate 35 to the inside of the cover 36 to the outside.
7 is drilled.

Next, a description will be given of a route through which condensed water adhering to the underside of the roof is discharged outdoors by the condensed water discharge device for the underside of the daylighting roof configured as described above.

First, condensed water adhering to the indoor side surface of the horizontal frame 5 (FIG. 3) at the upper end of the roof flows down along this surface and is collected in the water catching groove 13 at the top. In addition, condensed water adhering to the indoor side surfaces of the upper side stile 15 and glass 3 of the opening/closing window 9 flows down along these surfaces and is collected in the second stage water catching groove 19 (FIG. 4). The condensed water adhering to the indoor side of Mume 7 is collected through the third stage water catching groove 23 (fourth stage).
(Figure). Furthermore, the condensed water adhering to the indoor side surfaces of the glass of the fitted window 10 and the lower end horizontal frame 5 flows down these surfaces and flows into the lowermost water catching groove 25.
(Figures 5 and 6).

The condensed water collected in each of these water-catching grooves 13, 19, 23, and 25 is then transferred to water guide portions 26 provided on both sides of the lower surface of the mullion 8 (or on one side of the lower surface of the vertical frame 6).
The water flows down along this water guide portion 26 to the lower end of the roof, flows further over the upper surface of the water guide plate 35, and is discharged outdoors through the through hole 37. It should be noted that condensed water adhering to the indoor side surface of the lower side stile 17 (Fig. 4) of the opening/closing window 9 seeps out from the packing 21 and collects on the top surface of the blind 7. A through hole 38 is formed on the side of the vertical frame 6 or mullion 8 that comes into contact with it.
If this hole 38 is provided, the condensed water that has adhered to the lower horizontal stile 17 and accumulated on the top surface of the nozzle 7 will flow into the vertical frame 6 or the mullion 8 through the through hole 38, and these members 6 and 8, reaches the upper surface of the water guide plate 35, and is discharged outdoors through the through hole 37 of the cover 36. The outflow path of the condensed water discharged in this manner is schematically shown in FIG. 8.

The reason why each gutter material is fixed through the heat insulating material 12 is to prevent condensation water from adhering to the outer surface of each gutter material when the gutter material is cooled when the gutter material is made of aluminum. Therefore, when the gutter material is made of a material with low heat conductivity such as synthetic resin, the heat insulating material 12 is not necessary.

(Effects of the present invention) The condensed water discharge device for the underside of the roof for daylighting according to the present invention is configured and operates as described above, so that the condensed water adhering to the underside of the roof can be efficiently discharged. It is possible to effectively prevent dripping into the room, so that it does not cause discomfort to the occupants or stain the floor surface, etc. Furthermore, when the condensation water draining device of the present invention is installed, even if the water-tightness of the glass fittings that make up the daylighting roof is incomplete and rainwater enters the underside of the roof, this rainwater can be removed by the condensation water draining system. Since rainwater is discharged outdoors through the gutter material, it is possible to prevent rainwater from dripping indoors.
