Abstract

(57) [Summary] [Purpose] To prevent snowfall with a small amount of warm water or water when it starts to snow, and to effectively melt snowfall with a large amount of water when there is a large amount of snowfall or when there is heavy snowfall. To do. [Structure] A pipe (3) having a water discharge hole (4) is provided in parallel with the roof (1), and a ridge (10) of the roof (1) is provided.
The sprinkler (2) is installed in the pipe, and the sprinkler (2) is connected to the pipe (3). Therefore, when it starts to snow, hot water or water is discharged from the water discharge hole (4) of the pipe (3), and when the amount of snowfall is large or snow is accumulated, the hot water or water is further sprayed from the sprinkler (2). ..

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow melting device that melts snow accumulated on a roof.

[0002]

[Prior Art]

 As a conventional snow melting device, a pipe for snow melting is arranged on the upper part of the roof, holes are made at predetermined intervals in the pipe, and the pipe is connected to a water source or a hot water source to obtain water or hot water. A water heater is used to melt the accumulated snow by spraying water from the upper part of the roof, or an electric heater or hot water pipe is laid on the base plate of the roof to heat the electric heater or to use the hot water pipe during snow accumulation. It is known that the entire roof is heated by supplying hot water to melt the accumulated snow.

[0003]

[Problems to be solved by the invention]

 By the way, the above-mentioned conventional techniques have the following problems. In the prior art like the former, when there is a large amount of snow, the snow melts only in the places where water or hot water flows, forming a so-called tunnel-shaped cavity, and then when running water is stopped, the peripheral part of the tunnel-shaped cavity is closed. Frozen, it becomes heavy and puts a heavy burden on the roof.

In addition, in the latter prior art, the installation cost for laying the electric heater or the hot water pipe is high, and the maintenance cost and the maintenance in case of breakdown are difficult.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a roof snow melting apparatus in which hot water or water is discharged from a water discharge hole of a pipe provided in parallel with a roof, and a sprinkler is connected to the pipe. The sprinkler is installed in the roof ridge.

[0006]

[Action]

 When it starts to snow, hot water or water is discharged from the water discharge hole of the pipe, and when the amount of snowfall is large or there is snow, the sprinkler also sprays warm water or water.

[0007]

【Example】

 The present invention will be described in detail with reference to the drawings. In Fig. 1, a ridge (10) of a roof (1) of a house is provided with a sprinkler (2) and a plurality of pipes (3) arranged in parallel with the ridge (10) of the roof (1), These sprinklers (2) and pipes (3) are kneaded into the pipes (5) on the wall surface of the house, and are connected to the hot water source (6) via valves (7) and (8).

As shown in FIG. 2, a large number of water discharge holes (4) are provided below the pipe (3) at predetermined intervals. The valve (7) is a water amount control valve that controls the amount of hot water supplied to the pipe (5), and it is desirable that the water amount can be adjusted in two steps, large and small, with one touch.

The valve (8) is a three-way valve, and is interposed between the drain pipe (9) extending downward and the wall pipe (5), and the hot water from the hot water source (6) is piped ( It can be switched to two positions, a position for supplying water to the pipe 5) and a position for draining water in the pipe (5) through the drain pipe (9).

When it starts to snow, the water flow control valve (7) is opened to a small flow rate in order to prevent the snow from falling on the roof. Then, hot water from the hot water source (6) is supplied through the pipes (5) and (3), and is discharged to the roof (1) through the water discharge hole (4) provided in the pipe (3). At this time, the sprinkler (2) does not operate due to the small flow rate and low head pressure.

When the amount of snowfall is large, or when it is snowing, the opening of the water quantity control valve (7) is set to a large value to provide a large flow rate. Then, the hot water from the hot water source (6) actuates the sprinkler (2) and sprinkles the entire roof. At the same time, a large amount of warm water is also discharged from the water discharge hole (4), so that warm water is supplied from above and inside the snow and the snow can be effectively melted.

As a hot water source, a boiler for a bath can be used, and it is of course possible to use tap water instead of the hot water source. Of course, a mixture of hot water from the boiler and tap water is also acceptable.

When the use is stopped, the three-way valve (8) is switched to drain the water remaining in the pipe (5) through the drain pipe (9).

[0014]

[Effect of the device]

 The effects of the present invention are as follows. (A) When the amount of snow is small, water is discharged only from the water discharge hole of the pipe, so it is possible to effectively prevent snow accumulation with a small amount of warm water. (B) When there is a large amount of snowfall or a large amount of snowfall, water is sprayed from the sprinklers in addition to the water discharge holes of the pipes to supply warm water or water to the entire roof from above and from the inside. Can be effectively melted. (C) The water remaining in the pipe can be drained. (D) The manufacturing cost is low and the maintenance is easy. (E) In case of fire, it can also be used for extinguishing. (F) The amount of water can be changed with one touch.
