opens. In addition, an upper ventilation hole 3 having the same structure as the lower ventilation hole 4 is provided in the upper part of the roof board 13, which is the bottom of the base box 3, that is, near the upper frame material 10, and is connected to the duct 26. It is connected to the room via a conduit 27.

In this embodiment, the heat collecting plate 5 is a folded plate-like body of a metal or synthetic resin plate, and a trapezoidal bent portion 30 protruding in a trapezoidal shape is interposed between the bottom pieces 29. 5, the upper and lower ends are interrupted near the upper and lower ventilation holes 3 and 4, and the upper discontinuous part 7 is placed between the upper end of the heat collecting plate 5 and the upper frame material 10, and the lower end of the heat collecting plate 5 It is attached inside the base box 2 with a lower discontinuity 8 between it and the lower frame material 11. Note that a separating piece 31 is interposed between the bottom piece 29 and the waterproof sheet 14 to maintain a gap between the bottom piece 29 and the waterproof sheet 14. In the base box 2, a heat insulating material is interposed between the roofing board 13 and the waterproof sheet 14. In addition, the side edge of the heat collecting plate 5 is attached to the fixing metal fitting 3.
2 in close contact with the vertical frame member 17.

The fixing fitting 32 has a receiving piece 34 placed on the vertical frame member 17 at the lower end of the raised portion 33 bent in an inverted U-shape.
and a side piece 35 that is bent along the side surface of the vertical frame member 17 is provided on its outer edge, and the heat collecting plate 5 is sandwiched between the side piece 35 and the vertical frame member 17. By doing so, the side edges are protected from rain and are firmly fixed. Note that the transparent plate 12 covering the upper part of the base box 2 is, for example, a glass plate, and the receiving piece 3
4 with a watertight material interposed therebetween,
The upper surface of the base 3 is fixed to the raised portion 33.
9 is fixed by pressing the upper surface thereof with a presser fitting 36 having a groove-shaped portion 40 having a watertight material on the lower surface. The upper and lower ends of the transparent plate 12 are attached to the upper and lower frame members 10 and 11, respectively, and are mounted on fixing metal fittings 41 having the same shape as the fixing metal fittings 32 of the vertical frame material 17 with a watertight material interposed therebetween. It is fixed by holding plates 42 and 43 with watertight materials extending from the upper and lower frame members 10 and 11 interposed therebetween.

The auxiliary heat collecting plate 9 is a plate made of the same material as the heat collecting plate 5, and its upper end is fixedly connected to the side piece 44 of the fixture 41 attached to the upper frame member 10. The lower end is the broken part 7 above the heat collecting plate 5
It extends above it and is covered by the upper ventilation hole 3 by an auxiliary heat collecting plate 9. Further, below the base box 2, there is another auxiliary heat collecting plate 9a that covers the lower ventilation hole 4.
The other auxiliary heat collecting plate 9a has its lower end fixed and connected to the side piece 44 of the fixing fitting 41 attached to the lower frame material 11, and its upper end is connected to the interrupted part under the heat collecting plate 5. 8 and extends above it. The auxiliary heat collecting plate 9 and the other auxiliary heat collecting plate 9a are both attached to the fixing metal fittings 32 of the vertical frame member 17 on both sides, and their bases 39
It includes a flange 51 to be placed on top and a side plate 52 depending from its inner edge.

However, in the solar heat collecting device 1 of the present invention, the air flowing in from the lower vent 4 is divided evenly above and below the heat collecting plate 5 while passing through the lower discontinuous part 8, and the heat is received by the heat collecting plate 5. By exchanging heat with the heat collecting plate 5 using solar heat and exchanging heat with the auxiliary heat collecting plate 9, the air is further heated, and the high temperature air can be discharged into the room from the upper vent 3. Furthermore, since the upper vent 3 is covered by the auxiliary heat collecting plate 9, rainwater and debris can be prevented from falling into the upper vent 3 even if the transparent plate 12 is damaged.

In FIG. 3, a draining plate 55 is provided on the bottom plate of the base box 2 below the bottom break, the upper end of the draining plate 55 extends upward beyond the lower end of the heat collecting plate 5, and is pasted on the waterproof sheet 14. At the same time, the lower end of the frame material 11 is lower.
Another embodiment is shown in which a slit-shaped through hole 56 formed in the lower part is penetrated and protruded to the outside of the base box 3.
By providing such a drainage plate 55, even if rainwater intrudes into the base box 2 due to breakage of the transparent plate 12 on the auxiliary heat collecting plate 9, the rainwater can be removed from the auxiliary heat collecting plate. Draining plate 55 after passing through plate 9 and heat collecting plate 5
Rainwater on the draining plate 55 can be discharged to the outside of the base box 2 through the through hole 56. Note that the condensed water that condenses on the lower surface of the transparent plate 12 can be discharged in the same manner as rainwater.

〔Effect of the invention〕

In this way, the solar heat collecting device of the present application has heat collecting plates that are interrupted near the upper and lower vents, and an auxiliary heat collecting plate that extends above the interrupted parts of the heat collecting plates. The air passing through the heat collecting plate can further exchange heat with the auxiliary heat collecting plate, and as a result, the high temperature air can be discharged from the room and the heat exchange can be enhanced. In addition, even if the light-transmitting plate is damaged, it can prevent rainwater and debris from falling into the upper ventilation hole, and can also prevent the room from becoming dirty.
