Next, FIG. 6 shows a state in which the collector 10 and water pipes are installed.

The collector 10 is a heat collector made of a metal plate such as an iron plate or an aluminum plate that has been treated to absorb solar heat easily, for example, coated with a paint such as semiconductor dispersion paint, or plated with a metal that easily absorbs solar heat. It is composed of a plate 11 and a heat collecting pipe 12 such as a copper tube or a vinyl pipe, and the heat collecting pipe 12 is fitted with the heat collecting plate or held by a welded structure.

In the drawings of the embodiment, the heat collecting plate 11 has three parallel concave portions 13, 13, 13, and a structure is shown in which the heat collecting pipes 12 are fitted and held in the respective portions (FIG. 3).

The collector 10 has a heat collecting pipe 12 welded to the upper surface of the heat collecting plate 11 (Fig. 8), and the heat collecting plate 1
1 to which the heat collecting pipe 12 is welded to the lower surface of the
) may be used.

The heat collecting plate 11 is formed to have a width that allows it to be laid between the tile beams 4, 4, and its length may be arbitrary, and it may be used singly or in combination.

The collector 10 has a unit that is laid between the tile beams 4 and 4, and the unit is connected to each tile beam 4.
Multiple units are laid in the direction of the slope of the roof between 4.

The ends of the heat collecting pipes 12, 12, 12 of each unit are connected by broken pipes 14, 14 so as to constitute one pipe, and the heat collecting pipes 12, 12 that are butted are fitted together. They are connected by a structure (Figure 6).

Each heat collecting plate 11 has its upper edge raised up and has a hooking edge 1.
5, and the hooking edge 15 is brought into contact with the lower surface of the tile beam 4, and the appropriate portions thereof are anchored and fixed by square-shaped metal fittings 16 that are fastened across the tile beam 4. .

The water pipes 5 and 5' are the outgoing pipes, and the water pipe 6 is the return pipe. A heat medium such as water is supplied from the upper end of the water pipe 5' and is sent to the collector 10 of each unit via the water pipe 5. , the heat collecting pipes 12, 12... of the collector 10 reach the water pipe 6, and the water pipe 6
The heat medium that has entered is sent into the heat storage tank 19 from its upper end.

In addition, 30 in FIG. 6 is a water drain valve, and 31 is a square-shaped metal fitting for fixing the water pipe.

A heat insulating material 7 such as glass wool is laid around the outer four peripheries of the collector group in which the collectors 10 are arranged side by side (FIG. 7) to make the space between the collectors 10 and the outer peripheral opaque tile portion B airtight.

Conventional opaque tiles b, b... are laid on the outer circumference of the collector 10, and transparent tiles 20, 20... are laid on the collector 10 (FIG. 2).

The transparent tile 20 is made of a transparent material such as glass or plastic so that sunlight passes through and illuminates the heat collecting plate 11.

Transparent of the roof tile 20 means that sunlight passes through it, and includes colorless transparent, colored transparent such as milky white, or semi-transparent.

The transparent tile 20 has the same basic appearance pattern, such as a waveform, as the surrounding opaque tile b, and its width and/or length can be increased or shortened as desired.

In the embodiment drawings, the transparent tile 20 is an opaque tile b
An example is shown in which the length is the same and the width is approximately three times as long.

Thus, the heat medium flowing through the heat collecting pipe 12 can collect heat via the heat collecting plate 11 by the sunlight passing through the transparent tiles 20, 20, . . .

As described above, in the present invention, since the roof tiles are transparent tiles and the collector is installed under the tiles, the collector device does not protrude above the roof tiles, and the appearance of the building is not spoiled.

Moreover, since the collector is simple and consists of a heat collecting plate and a heat collecting pipe, the device can be made compact, and the collector can be formed between the roof tiles and the roof tiles between each tile frame. It is possible to effectively utilize the space available for installation.

Therefore, it is not only easier to transport and install the collector, but even when installed on the roof of an existing building, it is possible to install water pipes that extend in the direction of the slope of the roof on each of the tile beams described later. It can be installed by simply providing a section, without the need for special processing on the roof sheathing board itself, and maintenance and inspection of the device can be done simply by peeling off the roof tiles, making maintenance easy.

Furthermore, since the cutouts are provided in the tile beams on both sides of the collector, water pipes extending in the direction of the slope of the roof can be arranged in the cutouts in the space between the shedding board and the roof tile.

Therefore, the heat collection pipes of each collector can be connected to the water pipes on both sides of the collectors laid between the tile beams, and each collector can be connected to the water pipes in parallel, creating a collector with excellent immediate effectiveness. can do.

In addition, a waterproof sheet was laid on the field board, so
There is no risk of water leakage even if the heat collecting pipe etc. is damaged, and since insulation material is placed around the outer periphery of the collector, the collector part and the space formed under the surrounding opaque tiles are airtight. It is possible to provide a roof device equipped with a collector that can improve the heat efficiency and has an excellent heat collection effect.
