[Effect of idea]

The present invention supplies hot air to the double hollow structure roof a covered with the roof covering member 3 through the hot air gap 2 over the sloped roof surface 1 as described above, and circulates the air to extinguish roof snow. In a snow removal device for a roof, the roof covering member 3 is formed of a plate member having grooved lines 3a and convex lines 3b alternately.
a. Cover the roof surface 1 with the protruding strips 3b directed in the direction of the slope of the roof surface 1, and drill hot air holes 4 at regular intervals in the direction of the eaves near the eaves of the roof surface 1.
A hot air conduit 5 is connected to the hot air conduit 5, and the end of the hot air conduit 5 is connected to the hot air discharge part 6 of the hot air supply device b. The hot air gap 3 is a snow melting roof with a double hollow structure in which the exhaust pipe 7 is connected to the exhaust hole 25 and the end of the exhaust pipe 7 is connected to the suction part 8 of the hot air supply device b. Hot air from the hot air supply device b is sent into the roof covering member 3 via the hot air conduit 5.
The surface is heated and the snow on the roof covering member 3 is melted and removed.

Of course, the snow that falls on the roof covering member 3 will also be gradually melted and removed.

In this case, this hot air is introduced from the eaves, passes through the hot air gap 2, and is discharged from the exhaust hole 25,
The exhaust air whose temperature has decreased after passing through the exhaust pipe 7 is sent to the hot air supply device b, where it is heated again and turned into hot air and sent into the hot air gap 2. In addition, the roof covering member 3 are the concave line 3a and the convex line 3
Since the uneven board material with alternating concave and convex strips is used, the hot air rises along the concave and convex strips, so the entire roof covering member 3 is heated evenly, making snow removal with excellent thermal efficiency possible, resulting in lower fuel consumption. This provides an energy-saving roof snow removal device that can save money in terms of energy savings.

In this case, when it is difficult to melt snow with just the hot air from hot air supply device b due to severe cold or heavy snowfall, it is more effective to introduce domestic waste heat from indoor 21 at the same time, and conversely, when there is light snow, It is also possible to reduce the temperature of the hot air from the hot air supply device b and introduce domestic waste heat at the same time, and this may be selected appropriately depending on climate conditions, snowfall conditions, etc.

This hot air supply device B uses the heat source of a large heater with a fan or a central heating system installed in the building, so it does not require much equipment or construction costs, and is economical in this respect as well. be.

In addition, during the summer period, by stopping the heat source of the hot air supply device b and sending only the air into the hot air gap 2, the heat between the hot air gaps 2 is removed and the indoor temperature is lowered, making it possible to live a comfortable life. .

Furthermore, in this double hollow structure roof a, the surface that comes into contact with snow is the roof covering member 3, and the lower roof surface 1 does not come into contact with snow, so there is almost no fear of condensation, no damage, and it is durable with peace of mind. We will provide a roof snow removal device that can be used, and in the case of a long tile stick roof during construction, a fastening metal fitting 11 will be installed on the roof.
It is extremely simple as it only needs to be fixed through the roof, so it can be installed easily and at low cost, regardless of whether it is installed on an existing roof or a newly constructed roof.

At this time, even if dew condensation occurs on the lower surface of the roof covering member, the condensed water is introduced into the condensation drain pipe via the condensation collection gutter, flows down into the connected snow melting drain pipe, joins with the snow melting water, and is drained. This also solves the problem of condensation.

Moreover, since the roof structure itself is a reinforced structure in which the roof covering member 3 is uneven, it can sufficiently withstand snow pressure.

Thus, the present invention provides an efficient, economical, and energy-saving roof snow removal device.
