Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trough structure with a snow melting device.

[0002]

2. Description of the Related Art Conventionally, in cold regions with a lot of snow, when a trough is attached to a building, a heavy load is applied to the trough due to the accumulated snow.
Also, the roof to which the metal fittings are attached needs to be strong, and the construction cost is high. In order to solve such a problem, Japanese Utility Model Publication No. 56-5717 and Japanese Patent Publication No.
It is known to attach a snow melting device to a gutter such as a trough or eaves gutter as described in Japanese Patent Publication No. 33656/33. In the snow melting device disclosed in Japanese Utility Model Laid-Open No. 56-5717, the other end of the heat pipe, one end of which is in contact with the heat supply source, is installed on the wall of the gutter. In addition, the snow melting device disclosed in Japanese Patent Publication No. 6-33656 includes a gutter hanger that fixes a fixed part to a building and supports it by a support arm, and a heat radiator that radiates heat from an outer peripheral surface. It is attached to the support arm of the gutter suspension in a state of being separated from the trough. These trough structures with snow-melting devices melt the snow with heat pipes and heat radiators installed in the trough, reducing the load on the trough due to snow accumulation and eliminating damage to the trough. is there.

[0003]

However, when the above-mentioned gutter with a snow-melting device is applied to a trough, since the snow is melted by the radiant heat from the heat pipe and the radiator, it hardly melts,
Snow away from the heat pipe and the heat radiator takes time to melt, and sometimes heavy snow may cause snow to accumulate.
Furthermore, at the time of rainfall, from the roofs on both sides where the troughs are attached,
A large amount of rainwater flows into the trough at a time, merges with each other, and turbulence occurs, which does not flow smoothly into the trough and drainage capacity decreases. Moreover, in the trough gutter structure with a snow melting device shown in Japanese Patent Publication No. 6-33656, the trough is attached to the roof support member, and the support arm is attached to the roof support member while the radiator is separated from the trough. They must be installed, laborious to install, and stronger roof supports must be used.
In addition, the supporting arm part comes out from the side in the trough,
It disturbs the flow of rainwater. Furthermore, the radiator is separated from the trough, and the radiator is installed so that it comes to the upper center inside the trough, and the warm air from the radiator rises higher than the upper center inside the trough. The snow on the bottom of the was difficult to melt and was a problem. Therefore, the present invention has been made in view of the above problems, and a first object thereof is to provide a trough structure with a snow melting device that can easily attach a trough and enhance the snow melting effect. . The second purpose is that even if a large amount of rainwater flows into the trough at one time from the roofs on which the trough is installed during rain, turbulent flow does not occur and it flows smoothly inside the trough. The present invention provides a trough structure with a snow melting device that does not reduce the discharge capacity.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object. According to the invention of claim 1, the bottom portion of a trough having a substantially groove-shaped cross section extends along the longitudinal direction. A tubular radiator is placed, and a plurality of water spray holes are formed in the longitudinal direction on the upper portion of the outer peripheral surface of the tubular radiator.

According to the second aspect of the present invention, in the valley gutter structure with a snow melting device according to the first aspect, a partition plate is provided upright along the longitudinal direction at substantially the upper end of the radiator.

According to the third aspect of the present invention, a tubular radiator is placed along the longitudinal direction on the bottom of the trough with a substantially groove-shaped cross section, and a partition plate is provided on the upper end of the tubular radiator. It is erected along the longitudinal direction.

The heat radiating body used in the present invention radiates heat from the surface of the pipe, and an electric heater pipe and a hot water radiating pipe are preferable. The electric heater tube is a tube in which an electric heating element such as a nichrome wire is passed, and the heat generated by passing electricity is radiated from the surface of the tube. In addition, the hot water radiating pipe circulates hot water boiled with a heater or hot water using geothermal heat inside the pipe using a pump, etc., and radiates heat generated from the hot water from the surface of the pipe. Is.

[0008]

According to the first aspect of the present invention, since the tubular radiator is placed along the longitudinal direction on the bottom of the trough having a substantially groove-shaped cross section, the support arm for supporting the radiator is provided. There is no need to install it, there is no need to put the supporting arm from the side in the trough, it does not interfere with the flow of rainwater, and the warm water from the radiator also melts the snow accumulated on the bottom of the trough. You can In addition, since a plurality of water sprinkling holes are formed in the longitudinal direction at the upper part of the peripheral surface of the tubular heat radiator, hot water is upwardly pumped from the plurality of water spout holes on the outer peripheral surface of the tubular heat radiator using a pump or the like. It is possible to melt the snow on the roofs on both sides of the trough and prevent the snow from falling even when it is snowing.

According to a second aspect of the present invention, in the valley gutter structure with a snow melting device according to the first aspect, since a partition plate is erected along the longitudinal direction at substantially the upper end of the tubular radiator.
When it rains, even if a large amount of rainwater flows from the roofs on both sides where the troughs are attached to the troughs at one time, the rainwater that flows from one roof is blocked by the partition plate, and the rainwater that flows from the other roof is It does not merge with each other, turbulence does not occur, and it is smooth in Tanihi
It flows to Su. Therefore, even if a large amount of rainwater flows into the trough at a time, the drainage capacity of rainwater does not decrease.

According to the third aspect of the present invention, since the tubular radiator is placed along the longitudinal direction on the bottom of the trough which has a substantially groove-shaped cross section, it is troublesome to attach the support arm for supporting the radiator. There is no need to extend the supporting arm from the side in the valley gutter, it does not interfere with the flow of rainwater, and the warm air from the radiator rises upward from the bottom of the valley gutter. The snow on the bottom of the gutter can be melted sufficiently. In addition, since a partition plate is erected along the longitudinal direction on the upper end of this tubular radiator, a large amount of rainwater flows into the trough from the roofs on both sides where the trough is installed at the time of rainfall. However, the rainwater flowing from one roof is blocked by the partition plate, does not join with the rainwater flowing from the other roof, does not generate a turbulent flow, and flows smoothly in the trough. Therefore, even if a large amount of rainwater flows into the trough at a time, the drainage capacity of rainwater does not decrease.
