DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a natural circulation type solar heat collection device for roof installation, which includes a heat collector section and a hot water storage tank section that forms a natural circulation circuit with the heat collector section.

Conventionally, this type of natural circulation solar heat collector is
Since it is installed on a roof plate such as a tile, the structure for installing it is complicated and takes time to construct, and it has disadvantages such as insufficient installation strength.

The first invention of the present application is a natural circulation solar heat collector for roof installation, which has an extremely simple structure for installation on a roof, and can be installed on a strong roof by simply installing appropriate members on the roof side. The purpose is to provide equipment.

In addition to the object of the first invention, the second invention of the present application provides a natural circulation type solar heat collecting device for roof installation that does not expose piping for water supply, hot water collection, etc. to the outside and has a good appearance. With the goal.

The details of the present invention will be described below along with the roof mounting structure. In Figures 1 and 2, rafters 1...... are supported in parallel to the roof structure surface of the building, and the rafters 1...
...A roof board 2 is stretched on top, and waterproof paper 3 is laid on top of it, and these rafters, field boards, and waterproof paper constitute a roof base material, and on this base material, slate,
The roof is covered with roof plates 4 such as metal plates, tiles, etc., and this roof surface approximately corresponds to the installation base area of the heat collector part 5a of the natural circulation solar heat collection device 5 to be installed. Leaving the shingles on the roof uncovered,
A frame-shaped heat collector support frame 6 that appropriately rises from the roof plate surface is fixed on this surface F where the roof plate is not laid, and the support frame 6 supports the heat collector part 5a of the heat collector 5 and also stores hot water. The tank portion 5b is placed on the roof plate 4.

First, the heat collector part 5a of the heat collector 5 has the third and fourth parts.
As shown in the figure, in this example, a type that heats liquid such as water is used, and its structure is such that the flat upper surface of the flat box-shaped heat collector case 7 is opened, a transparent glass 12 is fitted into it, Inside the case 7 is the lower base tube 8.
and an upper base pipe 9 are installed, and a heat collecting plate 11 having a large number of channels 10 through which hot water flows is connected between the two base pipes, and the four peripheral walls of the case 7 of such a heat collector A rectangular frame-shaped hanging plate 16 integrally extends downward from the lower end. 17... is case 7
The tight material receiving grooves 18 provided on the four peripheral edges of the bottom are tight materials such as rubber which are fitted into the receiving grooves 17, respectively, and form a frame shape as a whole. 19 is a heat insulating material inside the case.

The other hot water storage tank section 5b has a hot water storage tank section 34 installed inside a tank case 33 as shown in the second and fifth figures, and is connected to the sloped upper part of the roof of the heat collector section 5a, and serves as a connection means. Connecting plates 35, 35, which have one end fixed to both left and right sides of the heat collector case 7, are fixed to both left and right sides of the hot water storage tank case 33 by screws 36. The piping related to this hot water storage tank 34 is as follows. In FIG. 5, the water supply pipe 37 connected to the water supply port on the upper part of the hot water storage tank 34 extends from the case 33 into the heat collector case 7 and extends downward through the bottom plate 13 of the heat collector case 7. A coupling ring 38 is provided at the extending end, and a circulation connecting pipe 39 connecting the outlet of the lower part of the hot water storage tank part 34 and the lower base pipe 8 of the heat collector is installed at an appropriate location in the heat collector case 7. A lower hot water sampling pipe 40 is connected, the hot water sampling pipe 40 extends downward through the case bottom plate 13, a coupling ring 41 is provided at the extending end, and a hot water storage tank 34 is provided.
The upper hot water sampling pipe 43 is connected to an appropriate location in the heat collector case 7 of the circulation connecting pipe 42 that connects the upper inlet of the heat collector with the upper base pipe 9 of the heat collector, and the upper hot water sampling pipe 43 is connected to the case bottom plate 13. A coupling ring 44 is connected to the extending end. The upper hot water sampling pipe 43 may be directly connected to a hot water sampling pipe outlet provided at the upper part of the hot water storage tank 34 without using the circulation connection pipe 42 . A drain pipe 45 is connected to the lower base pipe 8 and extends downward through the bottom plate, and a coupling ring 46 is provided at the extending end. In this case, when installing the antifreeze valve without installing drain piping, it is sufficient to simply provide a drain nozzle that penetrates the lower side surface of the collector case as in the conventional case.

Next, the heat collector support frame 6 is made by grounding four wooden frame members 20 having a rectangular cross section, and the outside dimensions of the frame are slightly smaller than the inside dimensions of the hanging plates 16 of the heat collector 5. This support frame 6 is placed on the waterproof paper 3 on the non-roofing surface F, and fixed to the roof board 2 or to the rafters 1 with nails, etc. In this example, the support frame 6 is A baseboard 21 is similarly fixed to the lower part of the slope and on the outside of both left and right sides of the support frame 6, and a flashing board 22 is attached to each frame member 20 and baseboard 21 of this support frame 6. ..., each frame material 20... as shown in the figure.
. . . From the top surface to the outside surface, and then the baseboard 21 ...... from the top surface to the outside surface and onto the waterproof paper 3 . 3. Spread each on 24...... and
Attach the upper end of each flashing board material 22 with nails, screws, etc.
3. The frame member 20 is fixed to the upper surface of the frame member 20, and the side ends of each flashing plate member 22 are welded and joined to each other in a watertight manner by folding or the like. Of the portions 24 of the flashing board material 22...... which are extended onto the waterproof paper 3, the extended portions above the roof slope and on the left and right sides are as shown in the third and fourth figures of the roof board 4.
. . . stacked on top of the roof board 4 . . . and bent its tip upward as a water return 25 . Also, the extended portion 24 at the lower part of the roof slope is stacked on top of the roof board 4 . . . as shown in the third figure. The tip is bent downward 26. The upper end portion of each flashing plate material 22 on the support frame 6 is bent 27 upward as a water return. Above rain cover plate material 2
2 is an annealed aluminum alloy thin plate, a metal thin plate such as a galvanized iron plate, or a synthetic resin sheet, preferably a bendable plate-like material.

In this example, the roof board 2 and waterproof paper 3 are not provided on the inside of the support frame 6, and the attic is left open.
It is also a good idea to put up field boards.

Next, each frame member 20 of the support frame 6 as described above...
On the upper surface of..., one side of the heat collector mounting material 28 made of angle material such as aluminum alloy is placed on the rain flashing board material 22, with the nails, screws, etc. 23...... or new nails, etc. In addition to fixing with screws etc.
The other side extends downward with a slight distance from the outside of each frame member 20, and the side ends of each mounting member 28 are watertightly joined to each other. 29 is each mounting material 28...
A fin-shaped tight material such as rubber is attached to the inner surface of the lower end of the support frame 6 to watertightly close the gap between the flashing plate material 22 and the mounting material 28 of the support frame 6.

Place the bottom surface of the heat collector section 5a on the support frame 6 to which the heat collector mounting material 28 is fixed as described above, and then attach the tight material 18 on the bottom surface to the mounting material 2.
8... While abutting the upper surface, the hanging plate 16 is fitted onto the outside of the mounting material 28, and in this state, the hanging plate 16 is attached to the mounting material 2 with the screws 30.
8......, and the hot water storage tank portion 5b is placed on the roof plate 4... through an appropriate receiving member 47.

In this case, the water supply pipe 37, upper and lower hot water sampling pipes 40, 43, and drain pipe 45 protruding from the bottom surface of the heat collector part 5a are located inside the frame-shaped support frame 6,
Then, pipes for water supply, hot water sampling, and drain are installed in the attic, and these pipes are connected to the above-mentioned pipes 37, 40,
43, 45 coupling rings 38, 41, 44, 4
6 respectively.

When installed as described above, for the heat collector section 5a, rain falling on the roof plate 4 flows down along the outside of the frame-shaped support frame 6 rising upward from the surface of the roof plate. It does not flow into the support frame 6. Even if rainwater reaches the height of the support frame 6, the fin-shaped tight material 29 prevents the rainwater from entering, and even if it reaches the upper surface of the support frame 6 beyond the tight material 29, the rainwater restraining plate material The upper water return bend 27 of 22...... prevents its entry. On the other hand, since the hot water storage tank 5b does not require strict watertightness due to its nature, it is generally susceptible to rainwater infiltration, and there is also a risk that water may overflow from inside, so it is placed on the roof board 4. It is effective that the

In the above example, the heat collector mounting material 28 is a long material that spans the entire length of the frame material 20, but it can also be a short material that does not include the tight material 29.

In the above example, the hanging plate 16 of the heat collector part 5a was indirectly fixed to the support frame 6 via the mounting material 28,
In some cases, the mounting material 28 may be omitted and the screws 30 may be inserted directly into the support frame 6 to directly fix the support frame 6.

It goes without saying that the solar heat collector of the present invention may also be of a type that heats gas such as air.

The natural circulation type solar heat collector for roof installation of the first invention of the present application has a simple structure for installation on the roof, with frame-shaped hanging plates extending from the four peripheries of the heat collector part. For example, if a frame body for supporting the heat collector part is fixed, the heat collector part can be placed on this frame body, and the frame-shaped hanging plate mentioned above can be fitted on it, and the hot water storage tank part can be placed on the roof board. This makes it possible to firmly install the entire heat collection device in a stable state, and its value in use is extremely high.

In addition to the effects of the first invention, the natural circulation type solar heat collecting device for roof installation of the second invention of the present application has the advantage that the water supply and hot water collection pipes are respectively protruded downward from the bottom of the heat collector part, so that the solar heat collecting device can be installed in the attic. It is possible to directly connect the provided water supply and hot water sampling pipes to the water supply and hot water sampling pipes without exposing them to the outside, thereby improving the appearance.
