DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar heat collecting apparatus using a roof main body, and an object of the present invention is to provide an apparatus which can collect solar heat simply and at low cost using the roof main body. .

[0002]

2. Description of the Related Art Various studies have been made on collecting solar heat on a roof surface. Conventionally, a general one is of a water heater type mounted on a roof or a wall, and has a large heat collecting area. Limited and not always efficient. Therefore, some proposals have been made for a solar heat collector using a roof body.

[0003] That is, in Japanese Patent Application Laid-Open No. 54-30617, a heat insulating material is laid on a roof structure, and a flat panel as a heat collecting portion is provided on the heat insulating material. A number of longitudinal through holes are provided inside, a water supply pipe and a hot water supply pipe are connected to the upper end and the lower end of the flat panel, and furthermore, a ridge is provided on the upper surface of the flat panel in the longitudinal direction, and such a ridge is provided. It has been proposed that a transparent or translucent surface plate is placed and fixed by utilizing the same, and furthermore, joints are provided on both upper sides of the panel and connected.

In Japanese Patent Application Laid-Open No. 54-127116, as a solar heat utilization apparatus applied to a mountain-valley-shaped deck plate-like roof, a heat collection unit is provided by using a mounting bracket attached to a valley as a saddle, and a roof ridge is provided. It has been disclosed that a drainage mounting member is provided at the crest portion forming the water drainage mounting member, a heat collecting plate is provided between the drainage mounting members, and a waterproof layer is formed.

[0005]

The disadvantage of the above-mentioned conventional general water heater system is described in Japanese Patent Application Laid-Open No. 54-30 / 1979.
617, etc.
In the case of 4-30617, since a flat panel having a large number of through holes must be adopted as a flat panel as a heat collecting part, material costs and construction costs for forming a roof are considerably expensive. I can't get it. Further, since the surface plate has a substantially waterproof structure on the roof surface, it is necessary to sufficiently provide a waterproof structure for the surface plate itself and the packing portions on both sides, and the materials and man-hours thereof increase in cost, and such a waterproof structure is also required. Of the roof itself, which impairs the function of the roof itself.

In Japanese Unexamined Patent Publication No. 54-127116, the heat collecting portion set with the mounting bracket as a saddle is separately formed, and in this case, the mounting work of the heat collecting plate does not directly cause a rain leak. However, since the heat collecting plate also aims to prevent heat radiation, it is necessary to interpose a packing material in order to obtain airtightness and to fasten it to a drainage mounting member using a cap or the like. As shown in the figure, the material cost and the construction cost have to be considerably increased.

Further, in these conventional devices, since a heat collector formed separately from the roofing material is used, the number of steps is large, and there is a high possibility that leakage will occur. In this case, it is necessary to supply water to the heat collecting section and to supply hot water to a heat collecting section located below a roof ridge corresponding to a so-called tile bar, as described in, for example, JP-A-54-30617. It is necessary to install the hot water supply pipe and the water supply pipe away from the roof surface (edge of the eaves) or to penetrate the roofing material such as a tile rod as described above. The conditions become complicated, and it is necessary to work hard for watertight construction, which inevitably increases the cost. In other words, the cost increase in the formation of the heat collecting section itself and the cost increase for such water supply and hot water supply are combined, and the construction cost of the roof for solar heat collection becomes considerably high.

[0008]

Means for Solving the Problems The present invention is studying on to solve the problems of the prior art as described above, such as tile bar-like protrusions formed in the intermediate portion of the roofing material to form a roof surface To form a heat medium flow-down space, and succeeded in obtaining an effective roof surface utilization solar heat collector at a relatively low cost with a simple configuration and easy workability, as follows. is there.

[0009]

[0010] A projection is bent along the length direction at the widthwise intermediate portion of the roof plate forming the roof surface, and a heat medium flow-down space is recessed and formed on the top surface of the projection. A solar heat collecting apparatus using a roof body, wherein ends are connected by a joint member to form a roof surface, and a cover is attached to the protrusion to cover a space for flowing a heat medium.

[0011]

[Function] By making the heat medium flow-down space indented in the roof plate for forming the roof surface, it is necessary to separately manufacture equipment for solar heat collection, thereby reducing the cost of this kind of equipment. In addition, solar heat is directly collected in the roof slab itself, so that efficient solar heat collection can be obtained, and leakage during the flow of the heat medium can be easily observed.

By connecting the shingles as described above to form a roof surface, the formation of the roof and the setting of the solar heat collector can be achieved simultaneously, at low cost and quickly, and a cover is provided in the space under the heat medium. By performing the application, dust prevention to the space under which the heat medium flows down, or prevention of the diffusion of the heat medium effective component can be achieved by a simple cover.

[0013] A protrusion is bent along the length direction at a widthwise intermediate portion of the roof plate forming the roof surface, and a heat medium flow-down space is recessed and formed on the top surface of the protrusion. To its stiffness in its length direction to improve its handling and workability. In addition, the space for flowing the heat medium is formed at an appropriate height from the roof surface, thereby facilitating connection of the liquid supply pipe and the hot water supply pipe, and also in this respect, the workability is improved.

[0014] By connecting the ends of the shingles with joint members as described above, the construction of the roof surface having solar heat collecting equipment can be performed in a simple manner almost in the same manner as when the shingles are constructed with ordinary shingles. .

Since the cover is attached to the projection to cover the space for flowing the heat medium, the cover can be easily and efficiently attached to the space for flowing the heat medium, and the cover is integrated to reinforce the roof surface. Then, the mounting state of the cover fitted and locked on both sides of the projection is stabilized.
