Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a snow melting device that melts snow accumulated on a roof.

(Prior art) Conventionally, this type of snow melting equipment generally has a metal pipe made of copper, iron, stainless steel, etc. placed between the roofing board and tiles, and a heating device such as a boiler runs inside this metal pipe. The heated water was circulated, and the heat emitted from the hot water heated the tiles, melting the snow that had accumulated on the roof.

(Problem that the invention aims to solve) However, in the conventional snow melting device described above, the efficiency of heat transmitted from the metal pipe to the tiles is poor, so the hot water temperature must be set high, and the heating device such as a boiler has to be set at a high temperature. There was a problem with rising fuel costs.

(Means for solving the problem) The snow melting device of the present invention is a device for melting snow accumulated on a roof, and includes a heat insulating material placed on the top surface of the roof board and a pipe through which a heat medium circulates. The tiles are placed on the heat insulating material, and roof tiles are placed on the pipe via a heat transfer member.

(Function) The heat insulating material and heat transfer member efficiently transmit the heat generated by the heated heat medium during pipe circulation to the roof tiles, thereby enhancing the snow melting effect.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the snow melting device of the present invention includes a heat insulating board 2 disposed on the top surface of a field board 1.
, a pipe 5 disposed on the heat insulating plate 2 through which a heated heat medium circulates, and a heat transfer member 6 interposed between the pipe 5 and the tile 3.

The heat insulating boards 2 are for preventing the heat generated when the heated heat medium circulates through the pipes 5 from being radiated to the roofing board 1 side. 3... are arranged so as to correspond to the respective horizontal rows.

The pipes 5 are made of metal or plastic, and are arranged on the heat insulating board 2 at appropriate intervals in the lateral direction so as to correspond to the rows of the roof tiles 3, for example. The pipe 5 is filled with a heat medium and connected to a heating device (not shown) such as a boiler, and the heat medium heated by the heating device is passed through a circulation pump (not shown). It circulates between the pipe 5 and the heating device. In this example, antifreeze is used as the heat medium, and this antifreeze has the characteristics of being easy to warm up, hard to cool down, and emitting far-infrared rays as exothermic energy. Note that the heat medium is not limited to antifreeze.

The heat transfer member 6 is for transferring the heat generated when the heated heat medium circulates through the pipe 5 to the tiles 3, and is made of a material with low thermal conductivity. The main body 6a of the heat transfer member 6 is formed so as to be in surface contact with the lower surface of the tile 3, and a recess 6b to be fitted into the outer circumferential surface of the pipe 5 is formed in the lower part thereof.

Next, the operation of this snow melting device will be explained.
The heat generated when the heat medium heated by the heating device circulates within the pipe 5 is transmitted to the tiles 3 via the heat transfer member 6. Here, since the heat transfer member 6 is formed of a material with low conductivity, the heat from the heat medium is gradually transferred and the heat is sufficiently stored. Then, heat is transferred from the heat transfer member 6 that has sufficiently stored heat to the tile 3, heating the tile 3, and the snow accumulated on the tile 3 is melted by this thermal energy. At this time, radiant heat due to far infrared rays of the heat medium (in this example, antifreeze) also acts, and due to their interaction, the efficiency of heat transmitted to the tile 3 is improved compared to the conventional case.

Furthermore, FIGS. 4 and 5 show another embodiment using mortar or cement as the heat transfer member, and the same members as in the previous embodiment are given the same reference numerals.

A heat transfer member 7 made of mortar is arranged between the heat insulating plate 2 and the tile 3 so as to sandwich the pipe 5 therebetween. The other configurations and operations are the same as those of the previous embodiment, and their explanations will be omitted.

(Effects of the Invention) As described above, the snow melting device of the present invention improves the efficiency of heat transmitted from the pipe side to the roof tiles, increases the snow melting effect, and reduces fuel costs for the heating device.
