JPH05287860A - Gutter for snowmelt-roof using hot air - Google Patents

Abstract

PURPOSE:To allow snowmelt-water to smoothly flow down without stagnation of the water on a roof, prevent water-leakage and decay, at the eaves, and prevent damage to a gutter when snow on the roof is melted by hot air produced by geothermal energy. CONSTITUTION:A caved-in and curved groove part 2 is provided on the upper face of a hollow body 1, the inside of the hollow body 1 is divided into a roof- side space part 4 and an eaves-side space part 5 by a partition 3, and a hot air inlet tube 6 connected to the eaves-side space part 5 is provided on the hollow body 1. Besides, plural through holes 7 are drilled in the partition 3, and plural blowout holes 8 continued to the roof-side space part 4 are drilled along the roof-side upper edge of the groove part 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter attached to the eaves of a roof in equipment for melting snow on a roof using air heated at a geothermal temperature as a medium.

[0002]

2. Description of the Related Art It has already been clarified that the geothermal temperature is naturally obtained, economically advantageous, and sufficiently effective for melting snow on the roof. However, the conventional rain gutter attached to the eaves of this kind of roof uses a U-shaped curve made of a synthetic resin or a thin iron plate.

[0003]

By the way, although the snow melting on the roof surface such as thatched roof or galvanized iron roof is melted as described above, it does not have the ability to melt in the water that melts and flows down, so the snow accumulated in the rain gutter remains as it is. The rest of the snow acts as a weir and the water that flows down from the ridge side collects at the eaves, causing not only a leak of rain but also a large amount of water in the snow accumulated in the rain gutter part, which increases the weight, causing damage. In some cases, this has the drawback of accelerating the decay of the eaves. The present invention is to eliminate the above drawbacks.

[0004]

Means for Solving the Problems A solution according to the present invention comprises a hollow body having a groove portion which is concavely curved in the upper surface, and a partition wall extending along the longitudinal direction in the inner space of the hollow body to form a roof side space portion and an eaves side space portion. The hollow body is provided with a hot air supply port leading to the eaves side space, the partition wall is provided with a plurality of through holes leading to the roof side space, and the hollow body blows warm air into the groove from the roof side space. It is characterized in that a plurality of jet holes are provided.

The hot air supply port may be provided so as to communicate with the roof side space portion, and the jet port may be provided so as to blow out from the eaves side space portion side.

[0006]

[Function] The warm air supplied to the eaves side space flows into the roof side space through each through hole of the partition wall and blows out into the groove from the jet port, so that the rain gutter is long. Warm air is blown out almost uniformly over the entire length of the rain gutter, which has the effect of melting snow over the entire length of the rain gutter. Therefore, it is possible to receive the snow melting water flowing down from the ridge side and drain it off. Not to mention the eaves protection.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS To explain the present invention in detail, as shown in FIG. 1, the outer shape forming a rain gutter is a hollow body 1 having a concave sectional shape, and a concave curved surface having a concave portion on its upper surface depressed. 1 is formed in a rectangular shape, it may be formed in a crescent shape as shown in FIG.

A partition wall 3 is provided along the longitudinal direction in the widthwise middle portion of the hollow body 1, and the partition wall 3 separates the interior into a roof side space portion 4 and an eaves side space portion 5.

Further, the hollow body 1 is provided with a warm air supply port 6 communicating with the eaves side space 5, a plurality of through holes 7 are formed in the partition wall 3 at intervals in the longitudinal direction, and further, in the groove portion 2. A plurality of ejection openings 8 are provided at intervals in the longitudinal direction at the upper edge portion of the rising wall on the roof side space portion 4 side.

Depending on how the rain gutter is attached, the roof side space 4 and the eaves side space 5 are reversed.
Further, the ejection port 8 may be provided not only on the roof side but also on the eaves side.

Further, as shown in FIG. 3 for the outline of the warm air snow melting apparatus, an outside air inlet 10 is provided in the basement 9 to guide the air in the basement 9 to the attic by the blower 11 and the pipe 12, It is sent to the air duct 13 formed between each rafter, and the roofing material 16 is provided through the small holes 15 formed in the base plate 14.
It blows out to the back side of. A branch pipe 18 branched from the pipe 12 of the above device is connected to the hot air supply port 6.

Since the air heated by the geothermal temperature is blown into the roof surface and the gutter 2 of the gutter, not only the roof surface but also the snow in the gutter is melted, and there is no obstacle in the rain gutter so that the melted water can be smoothly run. Can be drained to.

[0013]

According to the rain gutter attached to the snow melting roof by the warm air of the present invention, the hollow body forming the rain gutter is divided into two parts by the partition wall, and the space from one space part to the other space from each through hole opened in the partition wall. Since it flows into the section, even if the hollow body is long, warm air can be blown almost uniformly over the entire length, and hot air can be blown out from each jet outlet, making a long rain gutter the entire length. It is possible to melt snow across, and because the rain gutter does not have snow and the snowmelt water flows smoothly, it becomes impossible to pool water especially in the eaves part of the roof, preventing rain leakage and decay due to it,
Moreover, the rain gutter is prevented from being damaged by the weight of snow, and the durability of the gutter is improved.
