Description

[Detailed description of the invention] The present invention relates to a snow-removing roof device that makes the roof area as small as possible and sprays snow-removing water from both sides of the roof, making it possible to efficiently remove snow from the roof. The configuration will be described in detail with reference to the accompanying drawings as follows.

The roof 1, which is rectangular when viewed from above, is formed with a pair of left and right sloped drainage roof surfaces 1L, 1R toward the center, and a water collection gutter 3 is arranged in the central length direction of the sloped drainage roof surfaces 1L, 1R. A water section 2 is formed, and a steeply sloped roof surface 16 is formed downward in the length direction of the eaves of the sloped drainage roof surfaces 1L and 1R, and the attic 5 of the roof 1 is formed into a cavity. A water sprinkling pipe 4 that sprinkles water toward the water collection section 2 is provided in the length direction on the end of the slope drainage roof surfaces 1L and 1R excluding the steep slope roof surface 16, and a water collection pipe 8 is connected to the water collection gutter 3. This water collecting pipe 8 is connected to a water receiving tank 6 installed on the back of the roof 1, this water receiving tank 6 and the water sprinkler pipe 4 are connected to each other by a water supply pipe 12, and this water collecting pipe 6 and the heat exchanger 1 are connected in series.
3 are connected to each other by a hot water pipe 14', and similarly, a heat exchanger 13 and a water receiving tank 6 are connected to each other by a cold water pipe 14.

A case is illustrated in which a central portion 2a is formed with slope drainage roof surfaces 1L and 1R to form a water collection portion 2.

The water receiving tank 6 and the water collection section 2 are connected to each other by a collection channel 7 made of a water collection pipe 8.

The water sprinkler pipe 4 and the water receiving tank 6 are connected by a water supply channel 10 consisting of a water supply pipe 12 and a water supply pump 11.

The water receiving tank 6 and the heat exchanger 13 are connected to a hot water pipe 14'
In addition, the water tank 6 and the heat exchanger 13 are connected with each other by a cold water pipe 14, and hot water is sent to the water tank 6 via the heat exchanger 13, and the cold water in the water tank 6 is returned to the water tank 6. A heating device may be provided in the middle of the water supply channel 10 to further heat the snow melting water before sending it out.

The heat exchanger 13 may be anything that changes cold water into hot water, such as an instantaneous water heater or a boiler.

In the figure, 9 is an overflow pipe, 15 is a pump, 17 is a valve, and 18 is an outer wall of the building.

Since the present invention is configured as described above, it has the following features.

1. The roof 1 has a water collection part 2 in the center, a pair of sloped drainage roof surfaces 1L and 1R on the left and right sides, and a sprinkler pipe 4 is installed at the tip of the eaves of the sloped drainage roof surfaces 1L and 1R. Since it is a snow-melting roof, if water is sent to the sprinkler pipe 4, the snow-melting water will flow from the tip of the eaves to the water collecting section 2.
The snow that falls on this roof 1 will come into contact with the snow melting water and melt because it will flow widely across the roof width and form a water flow surface.

Therefore, while it is snowing, by sending water to the sprinkler pipe 4, the snow melting water that flows over the entire roof will gradually melt and melt the snow, resulting in an excellent snow melting roof. .

In this case, snow melting water heated using the heat exchanger 13 is sprayed from the sprinkler pipe 4.
Snow melting water at a temperature of 10 to 20 degrees Celsius can be obtained, so even if the outside temperature drops below 0 degrees, the snow melting water will not freeze and can reliably melt the snow.

2 Since this melted water is collected and recovered in the water collecting section 2, the roof surface will not be flooded and there is no need to worry about freezing.

3 The water collected from this water collection part 2 is collected in the water receiving tank 6, and this collected water is sent to the water sprinkler pipe 4 again.
There is no need to worry about snow melting water because it is a forced circulation system that sends it to the water tank to melt snow, and there is no need to worry about ground subsidence due to conventional well drilling, so it can be used with confidence. Since it is installed in the attic where the traffic is concentrated, the snow melting water in the water tank 6 is heated to some extent by this indoor warm air, so snow melting water with even higher temperature can be obtained.
Furthermore, the amount of snow removed from the heat exchanger 13 is reduced accordingly, which is economical.

4 Moreover, the roof 1 has sloped drainage roof surfaces 1L and 1R.
Cut both ends of the eaves diagonally to create a steeply sloped roof surface 1
6 to make the area of the roof as small as possible, the snowfall area is also reduced, and snow removal can be done with higher efficiency.

The snow on this steeply sloped roof surface 16 does not slide down and accumulate because of its steep slope.

5 Furthermore, since the attic 5 of the roof 1 is used as a cavity, residual heat from the stove and indoor exhaust heat, that is, indoor warmth, is concentrated in the attic 5, so the heat concentrated in the attic 5 also heats the roof 1. Since the snow will be removed, snow removal will be more effective.

6 The hollow part of the attic 5 can be used to provide a water tank 6 and to pipe a collection channel 7, a water supply channel 10, etc., thereby providing a snow-removing roof device with a good external appearance.

7. Thus, the present invention provides a snow-removal roof device for areas with heavy snowfall that does not require groundwater and can be safely used in buildings in densely populated areas.
