Abstract

PURPOSE:To display dielectric function early by providing a tile, formed of thermosetting resin material, with built-in heaters so as to heat the tile itself directly. CONSTITUTION:A tile body 1 formed of unsaturated polyester and the like is provided. with built-in longitudinal protrusion parts 2 with heaters 3 disposed parallely therein to form a tile 10. The tile bodies 1 are provided at two places avoiding the overlap of the protrusion parts 2 at the rate of one tile body 1 to two longitudinal existing tiles. Since snow piling up on a roof is largely accumulated at a snow hood, and the eaves tip part is of dynamically weak structure, the tile 10 is provided at the eaves tip part. The tile 10 can be thereby heated directly, and a snowfall can be melted rapidly.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a roof tile having a snow melting function.

[0002]

2. Description of the Related Art Conventionally, as a method for melting snow accumulated on a roof, a sheet heater is laid under a fired tile to heat the fired tile, or a pipe is arranged above or below the roof tile to be installed in the pipe. A method was used to warm the roof tiles by sending warm antifreeze or air.

[0003]

However, when a seat heater is installed under the fired tile, heating to the fired tile is indirectly performed via air, and a pipe is provided above or below the roof tile. In case of arranging, since the contact area between the fired roof tile and the pipe is small, it takes a long time to reach the temperature at which the fired roof tile melts the snow, and the snow falling on the roof is quickly melted at the same time as the snowfall confirmation. I couldn't get started.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a roof tile having a function of quickly melting snow falling on the roof.

[0005]

[Means for Solving the Problems] The solution according to the present invention comprises a roof made of synthetic resin having a unit similar to that of a plurality of prefabricated roof tiles on the roof, and a heater is built in the roof tile. It is characterized by

[0006]

The roof tile of the present invention has good thermal efficiency because it is integrally molded of synthetic resin, and since it is directly heated by the built-in heater, the temperature of the roof tile rises rapidly as soon as the power is turned on and snow falls on the roof. Is to melt quickly.

[0007]

Embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the roof tile 10 is composed of a roof tile body 1 made of a synthetic resin and a ridge portion 2 containing a heater 3. The roof tile body 1 has 1 unit with the same form as that of roof tiles with 4 prefabricated roof tiles 2 vertically in 2 rows, and the back of the roof tile body 1 has a ratio of 1 to 2 prefabricated roof tiles. Therefore, when the vertically long ridges 2 are roofed on the roof, they are provided at two locations avoiding the overlapping area for each unit. At the time of molding, two heaters 3 are installed side by side in each ridge 2, and the power supply terminals 4 of each heater 3 are pulled out from the lower end face of the ridge 2. The roof tile 10 is formed by a low-pressure molding method using a thermosetting resin such as an unsaturated polyester resin.

Needless to say, the number of heaters 3 arranged in parallel on the ridge portion 2 is not limited to that in the above embodiment. Further, a heater may be built in the roof tile body 1 without providing the ridge portion 2 on the back surface.

The roof tile according to the present invention may be roofed on the entire surface of the roof, but snow accumulated on the roof is accumulated as snow canopy particularly on the eaves, and the eaves part has a mechanically weak structure. , It is desirable to put it on the eaves part. Moreover, as shown in FIG.
Each heater 3 to the power supply (AC 100 or 200 V)
The power supply terminal 4 is connected, but an earth leakage breaker (not shown) is provided in the circuit for safety. In this example, a self-controlled heater was used as the heater 3.
There is no need for long time to melt snow on the roof like before, as soon as the power is turned on

As described above, according to the present invention, since the roof tile is integrally formed of synthetic resin and the heater is built in the roof tile, thermal efficiency of the roof tile is improved and the roof tile can be directly heated.
Therefore, the time required to raise the temperature of the roof tiles is shortened, and the snow accumulated on the roof can be quickly melted when the power is turned on without having to spend a long time on the snow melting of the roof unlike the conventional case.
