Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hot-air supply type roof snow melting apparatus capable of satisfactorily melting snow on a roof.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, various snow melting devices for melting snow on a roof have been proposed, but each has various drawbacks.

For example, in the type that melts snow on the roof by flowing groundwater to the roof surface, there are various drawbacks such as the problem of lack of groundwater and the problem that the roof is severely damaged because a large amount of groundwater flows down the roof surface. After all, the current situation is that no sufficient proposals have been made yet.

[Means for solving the problem]

 The detailed description will be made with reference to the accompanying drawings.

An exhaust main pipe 2 is arranged on the roof 1 in a state orthogonal to the eaves edge, and a plurality of exhaust branch pipes 3 are connected to the exhaust main pipe 2 in a state parallel to the eaves edge so that the hot air flows into the exhaust main pipe 2. The introduction pipe 4 is continuously provided, and the hot air supply device 5 is continuously provided to the hot air introduction pipe 4.
The exhaust hole 6 of the exhaust branch pipe 3 is bored so that the warm air exhausted from the exhaust hole 6 is directed downward, and the hot air is discharged to the connecting portion between each of the exhaust branch pipes 3 and the exhaust main pipe 2. The present invention relates to a hot-air supply type roof snow melting device, which is provided with a hot-air blocking plate 11 that allows or blocks passage.

[Action]

When the roof 1 surface is covered with snow and the warm air supply device 5 is operated, the warm air from the warm air supply device 5 passes through the warm air introduction pipe 4 and the exhaust main pipe 2, and then from the exhaust branch pipe 3 and the exhaust hole 6. The entire surface of the roof 1 is exhausted, and the hot air melts the snow on the roof 1.
At this time, since the warm air from the exhaust hole 6 is exhausted downward,
So much effective snow melting is achieved.

Further, since the exhaust branch pipe 3 is provided in parallel with the front edge of the eaves, the exhaust branch pipe 3 also functions as a snow slip prevention material that slides down the roof 1 surface.

Furthermore, since a hot air blocking plate 11 that allows or blocks the passage of hot air is provided at the connecting portion between each exhaust branch pipe 3 and the main exhaust pipe 2, the hot air from any exhaust branch pipe 3 is blocked. Exhaust is possible and the amount of warm air can be adjusted.

〔Example〕

In this embodiment, a burner that is used for drying grain in the autumn and is not used at all in the winter is used as the hot air supply device 5, and the hot air introducing pipe 4 is connected to the burner to stand along the wall of the house 14. The exhaust main pipe 2 is disposed in the warm air introduction pipe 4 along the slope of the side edge of the roof 1, and the exhaust main pipe 2 is provided with the exhaust branch pipe 3 in which downward exhaust holes 6 are formed at appropriate intervals. A plurality of eaves are arranged in parallel with each other in an orthogonal state.

Further, the drawing shows the case where the exhaust branch pipe 3 is fixed to the angle member 7 attached to the roof 1 surface by the fixing U-shaped rod 8.

 Reference numeral 9 in the figure is a nut.

In the drawing, a rotary shaft 10 is erected in the exhaust branch pipe 3 at the connecting portion between the exhaust main pipe 2 and the exhaust branch pipe 3, and a disc-shaped hot air blocking plate 11 is attached to the rotary shaft 10 to rotate the rotary shaft 10. The case where an L-shaped hot air switching plate 12 for rotating the moving shaft 10 is attached to the upper surface of the exhaust branch pipe 3 is shown. When the L-shaped warm air switching plate 12 is positioned as shown in FIGS. The hot air blocking plate 11 closes the inner hole of the exhaust branch pipe 3, and the L-shaped hot air switching plate 12 is moved 90 ° in the direction of → in FIG.
When rotated, the warm air blocking plate 11 rotates and the inner hole of the exhaust main pipe 2 and the exhaust branch pipe 3, that is, the warm air passage space becomes the widest.

Therefore, the amount of warm air introduced into each exhaust branch pipe 3 can be easily adjusted by rotating the L-shaped warm air switching plate 12 attached to each exhaust branch pipe 3, and the snow on the roof 1 surface will not be covered. Even in a uniform case, a desired amount of hot air can be introduced to a desired location by operating the L-shaped hot air switching plate 12, and snow can be melted very efficiently.

Reference numeral 13 in the drawing denotes a fastening screw, and by tightening the fastening screw 13 by hand, the L-shaped hot air switching plate 12 can be easily attached to the exhaust branch pipe 3.
Can be attached to the upper surface of.

FIG. 5 is an explanatory diagram of a case where the snowfall is carried out during snowfall, and the warm air blown downward allows the snowfall to be efficiently melted from the lower surface.

Since this product is for melting snow using warm air,
When the snow height reaches a certain level, warm air is blocked by the snow,
From the viewpoint of energy saving, it is desirable to operate it in a state where warm air does not escape to the outside air.

 In the figure, reference numeral 15 is snow and 16 is a fixing bolt.

[Effect of device]

Since the present invention is configured as described above, it is to provide a hot-air supply type roof snow melting apparatus which can easily perform good snow melting on the roof surface and at the same time prevent slipping of snow on the roof surface.
