Description

[Detailed description of the invention] [Field of industrial application] The present invention is an improved idea for a snow melting device for a sloped roof, and relates to a snow melting device for a sloped roof that can reliably melt snow over the entire roof surface. .

[Problems to be solved by conventional techniques and ideas]

In general, shops often adopt a type of roof that has a sloped wall surrounding the roof to prevent snow from falling on top of the storefront, and to improve the appearance of the store.

Although this sloping enclosure wall was useful for preventing snow from building up in the eaves, if a large amount of snow accumulated within the sloping wall, the snow had to be removed, which was very troublesome.

[Means for solving problems]

The present invention is intended to solve these drawbacks, and the structure of the present invention will be described in detail with reference to the accompanying drawings.

A snow collecting part 2 is formed at the lowest part of a roof a around which a surrounding sloped wall 1 is erected, and a running water part 3 is formed by giving a running water gradient in the length direction of this snow collecting part 2.
A drain pipe 4 is installed vertically on the lower side of the snow collecting section 2, a main pipe 5 for supplying hot air is arranged in the center of the snow collection section 2, and branches for discharging hot air that reach the enclosure slope wall 1 are installed on both sides of this main pipe 5. The pipes 6 are protruded in parallel, the hot air blower pipe 7 connected to one end of the main pipe 5 is connected to the hot air supply section 8, and the tip of the branch pipe 6 is exposed to the inside of the enclosing inclined wall 1 to form an enclosing inclined wall. This device is characterized by blowing warm air into the interior of the device.

[Effect]

The hot air from the snow melting boiler 9 that fills the warm air supply section 8 that ignites the snow melting boiler 9 is sent to the main pipe 5, and the warm air is released from the branch pipe 6 into the enclosure slanted wall 1 and the entire surface of the roof surface A, and is then released onto the roof. snow melts.

The snowmelt water flows down to the drain pipe 4 by the water flow section 3 on the roof and is drained.

FIG. 1 shows a case where a blower 20 that can be switched between strong and weak blowers is installed in the middle of the hot air blower pipe 7. When the snow melting boiler 9 is ignited to supply warm air to the snow melting device, the fan is set to high. , when the snow melting boiler 9 is turned off at night, the fan is switched to low to introduce indoor warm air into the hot air blower pipe 7, and the indoor warm air is sent to the snow melting device to prevent the snow melting section from freezing. It shows.

21 is a damper, 22 is a heat exchanger, 23 is a fuel tank, and 24 is a motor.

The hot air supply unit 8 in the drawing is provided outside the house, a snow melting boiler 9 is provided in the warm air supply unit 8, and the cover body 25 is fitted onto the snow melting boiler 9 with its lower end raised. There is.

The exhaust pipe 26 of the snow melting boiler 9 is connected to the drain pipe 4 to heat the snow melt water flowing down the drain pipe 4 and to prevent the drain pipe 4 from freezing.

In addition, the drawing shows that an intake pipe 27 is provided inside the enclosure inclined wall 1, and the tip of this intake pipe 27 is made to face the lower end of the cover body 25, thereby supplying warm air instead of cold air into the cover body 25, and at the same time supplying warm air to the living room, kitchen, bathroom, etc. Introductory windows 28 on the ceiling wall of the room introduce warm air from each room into the attic space.
A case is shown in which an insertion device 29 is provided for inserting the warm air from the attic into the hot air supply section 8.

[Effect of idea]

As described above, the present invention forms a snow collecting section at the lowest part of a roof with surrounding sloped walls, and forms a running water section by forming a running water gradient in the length direction of this snow collecting section.
A drainage pipe is installed vertically on the lower side of this flowing water area, a main pipe for supplying hot air is installed in the center of the snow collection area, and branch pipes for discharging hot air that reach the enclosure slope wall are installed on both sides of this main pipe. The hot air blowing pipes, which are protruding in parallel and connected to one end of the main pipe, are connected to the hot air supply section, and the tips of the branch pipes are made to face the inside of the enclosed inclined wall to blow hot air into the enclosed inclined wall. Because of this, a large amount of warm air is emitted not only near the snow collection area, but also the entire roof surface and inside the enclosure sloped wall, so it not only accumulates snow in the snow collection area, but also accumulates snow on the edge of the roof near the slope wall. The melted snow water is immediately drained from the drain pipe without collecting on the roof surface by the running water section with a running water slope, so the snow melting water does not freeze and the roof snow melting is performed very well. Become.

Moreover, this device does not emit hot air only to a part of the roof, but rather to the entire surface of the roof, including the inside of the sloped wall of the enclosure, so the entire underside of the snow is heated, which improves snow melting. For example, the snow melts only in the vicinity of the hot air discharge part, and the snow does not melt in a tunnel-like manner, which prevents the snow from melting properly.This means that snow melting is always carried out efficiently, demonstrating excellent practicality. This is a snow melting device for sloped roofs.
