Description

[Detailed description of the invention] [Technical field] This invention prevents debris and rainwater from entering the vent even if the transparent plate etc. is damaged by installing it below the heat collecting plate of the vent. The present invention relates to a solar heat collector.

[Background technology]

Pneumatic solar heat collectors that heat the air using solar heat are known, but especially in roof-integrated solar heat collectors, the vents open on the roof surface, so the upper translucent plate is When it is damaged,
Fragments of the building were likely to fall into the building, making maintenance and repair time-consuming, and there was a risk that rainwater would enter the building and stain the building.

[Purpose of the invention] The object of the invention is to provide a solar heat collecting device that can solve the above problems by covering the ventilation holes with a heat collecting plate.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, a solar heat collecting device 1 houses a heat collecting plate 3 in a base box 2 that is installed at an angle, covers the upper part with a transparent plate 4, and opens a vent 5 below the heat collecting plate 4. The base box 2 is built integrally with the roof on a waterproof sheet 9 laid on roof boards 8 stretched over rafters.

The rafter F is spanned between the ridgepole 21 and the nose purlin 22 with its tip portion protruding from the nose purlin 22, and the roofing board 8 is constructed across the entire surface of the rafter F. Therefore, since the waterproof sheet 9 is attached to the flat sheath board 8, the sheath board 8 can be reliably made watertight.

The base box 2 is formed on a waterproof sheet 9, and on the rafters F, a vertical crosspiece f1 extending from the ridgepole 21 to the vicinity of the nose purlin 22... and a horizontal crosspiece connecting the upper end back of the vertical crosspiece f1. It is a box-shaped body with an open upper part and a peripheral frame formed by a crosspiece f2 and a horizontal crosspiece f3 connecting the front ends thereof, and the vertical crosspiece f1 is
By being placed on the shedding board 8 in the same direction as the rafters F, the vertical beams f1, and therefore the base box 2, are inclined at the same angle as the rafters F. Further, the lower end of the vertical crosspiece f1 is interrupted near the upper part of the nose purlin 22, so that the shedding board 8 protrudes from the lower end of the base box 2 toward the eaves.

In this embodiment, the heat collecting plate 3 is a folded plate-like body of a metal or synthetic resin plate, and a trapezoidal bent portion 27 protruding in a trapezoidal shape is interposed between the bottom pieces 26. The board 3 has an interrupted part 29 between it and the horizontal crosspiece f3.
It is installed over almost the entire surface of the base box 2 up to the upper end. Note that a separating piece 30 is interposed between the bottom piece 26 and the waterproof sheet 9 to maintain a gap between the bottom piece 26 and the waterproof sheet 9. Inside the base box 2, a heat insulating material is interposed between the roofing board 8 and the waterproof sheet 9. Also, the heat collecting plate 3 has its both side edges fixed to the vertical crosspiece f1 by the fixing fittings 32.
It can be installed in close contact with the

The fixing fitting 32 has a receiving piece 34 placed on the vertical crosspiece f1 at the lower end of the raised part 33 bent in an inverted U-shape.
and a side piece 35 that is bent along the side surface of the vertical crosspiece f1 is provided on its outer edge, and the heat collecting plate 3 is sandwiched between the side piece 35 and the vertical crosspiece f1. By doing so, the side edges are protected from rain and are firmly fixed. Note that the transparent plate 4 covering the upper part of the base frame 2 is fixed using the fixing fittings 32. The transparent plate 4 is, for example, a glass plate, and is placed on the receiving piece 34 with a watertight material interposed therebetween. Channel 4 with watertight material
The upper surface thereof is pressed and fixed using a presser metal fitting 36 having a diameter of 0. Note that the upper and lower ends of the transparent plate 4 are provided with presser plates 4 extending from the upper and lower horizontal crosspieces f2 and f3, respectively.
1 and 42, and is fixed with a watertight material interposed therebetween.

The roof board 8 has a lower ventilation hole 5 and a heat collecting board 3.
The heat collecting plate 3 covers the upper part of the heat collecting plate 3.

The ventilation hole 5 has a V-shape with a symmetrical slope with a relatively gentle slope on the top side, and a flat shogi piece shape with the side and bottom sides in a U-shape, and is formed by cutting out the roof board 8. Since the ventilation hole 5 is formed to have a length spanning almost the entire width of the heat collecting board 8, and its lower side is located above the discontinuous end 29a of the heat collecting board 3, the ventilation hole 5 is It opens below the heat plate 3 and is covered by the heat collecting plate 3. Also vent 5
A water-blocking frame is provided. This water-shielding frame has a raised piece 44 extending upward along the periphery of the vent 5 to prevent rainwater from flowing in, and also prevents rainwater from flowing in.
4 is provided with a leg piece 45 facing outward at its lower end, and the waterproof sheet 9 is attached to the upper part of the leg piece 45.
By overlapping them with a watertight material in between, the space between the upright piece 44 and the waterproof sheet 9 is made watertight. Note that a horizontally elongated duct 47 surrounding the vent 5 is attached below the vent 5, and a conduit 49 leading to the room opens into the duct 47. Incidentally, the roof board 8 is provided with an upper vent 10 having the same structure as the vent 5, and is connected to the room via a conduit 51 connected to the duct 50.

In addition, the horizontal crosspiece f3 located below has a through hole 11.
... are arranged in parallel, and the porous material 6 is attached through the through holes 11. In this embodiment, the through hole 11 is cut out in a U-shape on the lower surface of the horizontal crosspiece f3, and therefore its lower part is open in contact with the waterproof sheet 9, and the through hole 1
1 is provided with a step 11a on its inner surface. Porous material 6
is made of a porous material, such as sponge, synthetic resin foam, or sponge, that has small pores that connect inside and outside and is weather resistant, and is attached to the through hole 11 using an adhesive or the like. The porous material 6 can lead and drain water such as rainwater and condensation water stored inside to the outside by its osmotic pressure, but can block ventilation from the outside.
Prevent heat loss. Note that a weather-resistant material is preferably used as the porous material.

Thus, the solar heat collecting device enables heating in winter by heating the air flowing in through the vents 5 by the heat collecting plate 3 that collects solar heat and discharging it from the vents 10. Furthermore, even if the translucent plate 4 is damaged, the fragments will be blocked by the heat collecting plate 3 and will not fall into the ventilation hole 5, thus reducing maintenance and repair work and blocking rainwater from entering the house. prevent the infiltration of

[Effect of idea]

As mentioned above, in the solar heat collecting device of the present invention, the vent is covered with a heat collecting plate, so even if the transparent plate is damaged, debris can be prevented from entering the vent, making maintenance and repair easier. It has many effects, such as reducing the time and effort required to do so, and also preventing rainwater from entering the house and preventing stains on the house.

Note that the solar heat collecting device of the present invention can be formed not only as a roof-mounted device but also as a box-shaped device that is placed on a roof or the like.
