The roof snow melting apparatus of the present embodiment is used, for example, for a roof plate 10 for cold regions such as a galvanized iron plate, and as shown in FIG. 1, FIG. 2 and FIG. A support bracket 20 made of stainless steel is installed horizontally between horizontal members (main building) 11 as a roof structural member to be installed on the back side, and is arranged on the back side of the roof plate 10 via the support bracket 20. A plurality of heat insulating materials 30 made of expanded polystyrene, a plurality of heat conduction panels (copper plate panels) 40 placed on the surface of the heat insulating material 30 with a groove 41 for embedding a pipe on the surface, A heat medium pipe (copper seamless pipe) 50 embedded along the pipe embedding groove 41 over the copper plate panel 40 is provided. Then, in order to automatically circulate hot water as a heat medium through the copper seamless pipe 50 during snowfall, the snowfall detection sensor 60 detects snowfall on the roof plate 10 and detects the snowfall, and from the snowfall detection sensor 60. A hot water circulating device 70 for circulating hot water as a heat medium through the seamless pipe 50 made of copper based on the detection signal is attached.

As shown in FIGS. 2 and 4, the support fitting 20 is composed of an elongated main body portion 21 having a substantially U-shaped cross section with a length substantially equal to the distance between the horizontal members 11. Side plate portions 22 fixed to the side surface of the horizontal member 11 by fixing means such as nails are integrally provided at both ends in the length direction, and a copper plate panel 40 is provided on the upper surface of the heat insulating material 30 at the upper end of the side plate portions 22. The fixing piece 23 fixed to the above is provided so as to extend upward in a bendable state (a state in which a triangular cutout is provided to facilitate bending).

The heat insulating material 30 prevents heat of hot water circulating through the seamless pipe 50 made of copper from escaping to the ceiling side, and is laid between the horizontal members 11 on the diagonal member (gassho) 12 by the support fitting 20. Then, the recess 31 into which the pipe-embedded groove 41 of the copper plate panel 40 is fitted is formed on the surface of the roof plate 10 that faces the back surface.

The copper plate panel 40 guides when the seamless pipe 50 is bent and meandered and is arranged. After the arrangement, the copper plate panel 40 supports the seamless pipe 50 and heat of a heat medium circulating in the seamless pipe 50. As shown in FIG. 3, the flat shape is square and the copper seamless pipe 50 is tightly fitted by pressing a thin copper plate as shown in FIG. Two pipe-embedding grooves 41 having a substantially U-shaped cross section are bulged toward the back surface side, and both ends parallel to the pipe-embedding groove 41 are also bent toward the back surface side. The pipe embedding groove 41 fits into the recess 31 when the copper plate panel 40 is placed on the surface of the heat insulating material 30.

The copper seamless pipe 50 circulates, for example, hot water as a heat medium, and transfers the heat of the heat medium to the copper plate panel 40 and the roof plate 10.

The snow cover detection sensor 60 is installed at an appropriate location on the surface of the roof plate 10, and is configured to detect only snow covered by snowfall on the roof plate 10 by combining an optical sensor, a temperature sensor and the like. Has been done.

The hot water circulation device 70 includes a hot water tank 71 equipped with a heater for heating hot water as a heat medium, a pump 72 for circulating the hot water in the hot water tank 71 through the copper seamless pipe 50, and a hot water tank. The tank 72 includes a heater and a pump 72, and a control device 73 that controls the pump 72 based on a detection signal from the snow detection sensor 60.

Next, a procedure for constructing the roof snow melting device will be described with reference to FIGS. 5 to 7.

As shown in FIG. 5, a plurality of horizontal members (main building) 11 are arranged on the diagonal members (gassho) 12 supporting the roof plate 10 so as to be orthogonal to the diagonal members 12, and are appropriately spaced. It is installed.

First, as shown in FIG. 6, the support fittings 20 are arranged between the horizontal members 11 at appropriate intervals along the axial direction of the horizontal member 11, and the side plate portions 22 of the respective support fittings 20 are hooked or the like. And fix it to the side surface of the horizontal member 11. Then, as shown in FIG. 7, the heat insulating material 30 is placed between the support fittings 20 and the heat insulating material 30 is laid between the horizontal members 11 with substantially no gap, and the copper plate panel 40 is recessed in the pipe embedding groove 41. Similarly, it is laid on the surface of the heat insulating material 30 so as to fit into the heat insulating material 31, and the fixing piece 23 is bent to the front surface side of the copper plate panel 40 to fix the copper plate panel 40 to the surface of the heat insulating material 30. After that, the copper seamless pipe 50 is pushed in along the pipe embedding groove 41. Accordingly, the seamless pipe 50 made of copper is arranged so as to meander along the pipe embedding groove 41 on the back surface side of the roof plate 10. Thereafter, one end opening of the copper seamless pipe 50 is joined to the supply port of the hot water tank 71, while the other end opening is joined to the return port of the hot water tank 71.

When snow falls on the roof plate 10 and there is snow, the snow detection sensor 60 detects this and sends a signal to the control device 73. The control device 73 monitors the temperature in the hot water tank 71. When the signal from the snow accumulation detection sensor 60 is input and the temperature of the hot water is not sufficient to circulate it as a heat medium, first, the hot water is heated. Power is supplied to the heater of the tank 71 to heat the temperature of the hot water to a temperature sufficient to circulate it as a heat medium. When the temperature of the hot water becomes sufficient to circulate it as a heat medium, a drive signal is output to the pump 72 to drive the pump 72. As a result, hot water heated to a predetermined temperature from the hot water tank 71 circulates in the copper seamless pipe 50, and the heat of the hot water is conducted from the copper seamless pipe 50 to the copper plate panel 40, while the copper seamless pipe is made. 50 and the copper plate panel 40 are transmitted to the entire roof plate 10 and snow falls on the roof plate 10 to melt the snow. Heat is taken away by the snow melting and the temperature is lowered, and the hot water returns to the hot water tank 71, is heated again by the heater, and is sent to the seamless pipe 50 made of copper. When the snowfall on the roof plate 10 is stopped, the control device 73 outputs a drive stop signal to the pump 72 to stop the pump 72 and stop the power supply to the heater. This stops hot water from circulating in the seamless pipe 50 made of copper. If snow falls again, hot water is circulated in the copper seamless pipe 50 in the same manner.

According to the roof snow melting apparatus of the above-mentioned embodiment, it is possible to surely melt the snow which falls on the roof plate 10 regardless of the temperature in the room and gives sufficient heat to the accumulated snow. In addition, unlike the case where the snow is melted by pouring water, there is no need to treat a large amount of wastewater used for melting the snow, and manual snow shoveling can be omitted. Further, since the seamless pipe 50 made of copper is embedded along the embedding groove 41 for construction, it is possible to construct with one seamless pipe 50 made of copper. It is simple, there is no risk of liquid leakage, and maintenance is easy.

Further, since the heat is conducted to the copper plate panel 40 so that the heat is also transmitted from the copper plate panel 40 to the roof plate 10, the heat can be evenly transferred to the entire roof plate 10 at a specific location. There is no danger of snowfall in the area.

Further, the heat insulating material 30 reduces the rate at which the heat from the hot water, which is the heat medium, escapes to the ceiling, and most of the heat is used for snow melting, so that the energy efficiency can be improved.

Further, since it is arranged to automatically circulate hot water to the back side of the roof plate 10 by detecting snowfall and snowfall on the roof plate 10, it is possible to monitor the snowfall and drive the device. Does not have to keep the device running in anticipation of snowfall.

Further, the roof snow melting apparatus of the present embodiment is for melting snow on the roof plate 10 by melting snow, but it can be diverted as a water heater utilizing solar heat in the summer. is there.

In the above-mentioned embodiment, the case where the copper plate panel is used as the heat conduction panel is shown, but the present invention is not limited to this, and it is possible to use a panel having excellent heat conductivity such as an aluminum plate. is there. Further, although the case where the copper seamless pipe is used as the heat medium pipe is shown, the present invention is not limited to this, and a pipe having an excellent thermal conductivity such as an aluminum plate may be used.
