Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for efficiently melting snowfall on a roof of a house, or on an open area such as a garden or a private road to prevent snow accumulation.

[0002]

2. Description of the Related Art In winter, in areas with a lot of snowfall, snow removal work such as removing snow from the roof or removing snow piled down from the roof under the eaves and moving to an appropriate snow storage location is performed every winter. It is inevitable, and in urban areas, the amount of transported snow increases costs and can be difficult to discard. Therefore, various snow melting apparatuses for melting such snow have been proposed.

[0003] For example, a snow melting apparatus according to Utility Model Registration No. 2028877 carries snow accumulated on a road or under an eaves and puts it into a snow melting tank, which is heated by a high-temperature combustion gas from a burner in a furnace arranged in the tank. Is to melt snow.

[0004] However, in this type of combustion type snow melting apparatus, since the snow melting tank is fixed on the ground or buried under the ground, heavy labor of manually transporting the snow to a place where the snow melting apparatus is installed is still required. Yes, it does not solve the problem of labor saving. Moreover, since the accumulated snow mass, frozen snow mass, ice mass, and their mixture have a high density and become extremely cold due to nighttime radiation, etc., enormous heat energy is required to melt or discharge the mass. However, there is a problem that the efficiency of converting the heat energy generated by the combustion as the melting energy is low, and the consumption of fuel and labor by humans become enormous.

[0005] In addition, a snow melting / snow-snow groove is buried by a concrete square tube having a square cross section of several tens of cm on each side, and each house manually transports and throws snow and ice blocks into the snow-smelting / snow drift. In addition, there is also adopted a method in which snow is melted off by sending water to flow away. However, this method involves burying a concrete square tube and extending the snowfall path, and thus requires a huge construction cost.

As a snow melting device for a roof of a house, a liquid feed pipe for passing hot water or antifreeze is provided on the back side of the roof material, and heat of the hot water or antifreeze in the liquid feed pipe is transmitted to the roof material. There is known one in which snow accumulated on the upper surface of a roofing material is melted.

However, in this type of device,
Since hot water and antifreeze have high viscosity, it is difficult to quickly supply heat energy to the entire long liquid supply pipe, and it is difficult to obtain a uniform snow melting effect on the entire roof due to a temperature gradient. In addition, since the liquid supply pipe is disposed behind the roof material, it takes time for heat to be conducted to the upper surface of the roof, and there is a risk that snow accumulated on the roof may slide.

[0008] Others melt snow using hot spring water or underground water, but those using hot spring water or underground water
Since there is a risk of land subsidence, there is a problem that the area where pumping and supply can be performed is restricted, and the equipment becomes large-scale.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a technical problem thereof is that a snowfall piece itself falling toward a roof or an open space is used. It is an object of the present invention to prevent snow accumulation by melting instantaneously when descending, and to enable snow melting efficiently with extremely little heat energy.

Heat is exchanged with the heated gas passing through the inside of the unit, and the mixture is melted to become liquid water and flows down from the surface of the air supply pipe unit toward the lower side. Since the heating gas sent into the air supply pipe portion has a small viscosity, heat energy can be quickly spread to the entire snow melting panel, and the temperature gradient can be suppressed to be small.

According to a second aspect of the present invention, in the snow melting panel having the structure of the first aspect, the heat radiation panel body is formed in an air mat shape from a sheet or film-like synthetic resin material. According to this configuration, since the heat radiation panel body is lightweight, the load on the roof and the like is extremely small, handling at the time of installation and removal is easy, and the thinness makes it possible to remove the snowflakes in contact with the surface. Heat exchange is performed efficiently.

According to a third aspect of the present invention, in the snow melting panel having the structure of the first or second aspect, a pipe joint portion is provided at one end of the upstream multiple air supply pipe portion and at the other end of the downstream multiple air supply pipe portion. And a plurality of heat radiating panel bodies are laid on the snow-prevention target surface in a state where a plurality of heat radiating panel bodies are connected via the pipe joint portion. According to this configuration, a required number of snowfall melting panels can be connected according to the area and shape of the snowfall prevention target surface, and can be laid so as to cover the entire snowfall prevention target surface.

According to a fourth aspect of the present invention, in the snow melting panel having the structure of the first or second aspect, the pipe joints are provided at both ends of the upstream multi-side air supply pipe section and at both ends of the downstream multi-side air supply pipe section. Provided, radiating panel body is laid on the snow-prevention target surface in a state where a plurality of radiating panel bodies are connected via the pipe joint portion,
The internal passages of the pipe joints located at the ends opposite to each other are closed between the upstream air supply pipe section and the downstream air supply pipe section. According to this configuration, the direction of the flow path of each snow melting panel can be arbitrarily selected depending on the connection / laying configuration of the snow melting panel.

According to a fifth aspect of the present invention, in the snowfall melting panel having any one of the first to fourth aspects, a water passage gap is formed between the intermediate air supply pipe portions of the heat radiation panel main body. According to this configuration, most of the water melted by the snowflakes coming into contact with the surface of the intermediate air supply pipe portion flows down from the surface of the air supply pipe portion to the snow accumulation prevention target surface through the water flow gap.

According to a sixth aspect of the present invention, in the snowfall melting panel having the configuration of the fifth aspect, each of the intermediate air supply pipe portions has a net,
They are connected to each other by strings or filaments. According to this configuration, by connecting the respective intermediate air supply pipe sections, the heat radiation panel main body is reinforced, and the generation of snow melting residue due to the snowflakes entering the water gap between the air supply pipes is prevented.

According to a seventh aspect of the present invention, in the snowfall melting panel having the structure of the fifth or sixth aspect, the heat radiation panel main body comprises:
It is laid in a state where it floats on the snow-prevention target surface via a plurality of support legs. According to this configuration, a gap is formed between the snow-prevention target surface such as the top surface of the roof,

It will be in the state of being lined up.

As shown in FIG. 5, among the snow melting panels 1, 1,... Laid on the upper surface of the roof R, the pipe joint portion 115 on the upstream side in the snow melting panel 1 on the most upstream side.
Is connected to the air supply pipe 2, and the downstream pipe joint portion 117 of the most downstream snow melting and melting panel 1 is connected to the exhaust pipe 3. An air tank 4, a blower or air compressor 5, and a combustion heat exchanger 6 are sequentially connected between the downstream side of the exhaust pipe 3 and the upstream side of the air supply pipe 2.

As the air tank 4, blower or air compressor 5, and combustion type heat exchanger 6, ready-made commercial products such as those for greenhouses can be used. The air tank 4 can be omitted when the number of connected snow melting panels 1 is small.

FIG. 6 is an explanatory diagram schematically showing an example of a connection form of the snow melting and melting panel 1. As shown in FIG. That is, when the number of laid snow melting panels 1 is relatively small, they may all be connected in series. However, when the number of laid snow melting panels 1 is large, as shown in FIG. panel connecting columns _{1A 1 ~1A 3, 1B 1 ~1B} 3, ... to,
By connecting the air supply pipe 2 and the exhaust pipe 3 in parallel with each other, the load on the blower or the air compressor 5 and the temperature gradient described later can be reduced.

FIG. 7 is an explanatory diagram showing the operation of the snow melting panel 1. The heat dissipating panel body 11 is installed so as to float from the upper surface of the roof R via the connecting net 12 and the short legs 13. 3 and a combustion type heat exchanger 6 pumped by a blower or an air compressor 5.
As a result, air heated to an appropriate high temperature is circulated. The heat dissipating panel body 11 is formed in the shape of an air mat made of vinyl chloride or the like. In addition, the inside of the heat dissipating panel exerts buoyancy due to the flow of warm air. Can be

Even in a heavy snowfall area, the number of times of heavy snow falls is about 4 to 5 times in one winter, and the number of days in which a strong winter-type atmospheric pressure arrangement is sustained per one time is usually about 2 to 3 days. Therefore, the snow melting panel 1 does not need to be permanently installed throughout the winter, and may be installed only during heavy snowfall. As described above, since the snow melting panel 1 is extremely light in weight, installation and removal operations are easy, and therefore, it is possible to quickly install and respond to a heavy snow warning or a heavy snow warning, for example.

Reference symbol S in FIG. 7 denotes a snowflake falling from the sky. Most of the snowflakes S do not reach the upper surface of the roof R, but contact the surfaces of the manifold air supply pipe sections 111 and 112 or the intermediate air supply pipe section 113 in the snow melting and melting panel 1 and heated air passing through the inner cavity thereof. Melted by the heat of And since these air supply pipe parts 111-113 are formed with a thin synthetic resin film, the heat exchange between the snowflakes S and the heated air that have come into contact is instantaneously performed and melted to form water droplets W. Further, since the synthetic resin forming the air supply pipe portions 111 to 113 has water repellency, the water droplet W is dropped onto the upper surface of the roof R without being attached to the synthetic resin surface due to surface tension. Further, the snowmelt water slides down the upper surface of the roof R and falls from the eaves to the ground.

As shown in FIG. 1 described above, the pipe joints 115 and 117 in each heat radiation panel main body 11 are
As shown in FIG. 2, since the air supply pipes 111 and 112 are provided near the opposite ends of the air supply pipes 111 and 112,
The length of the air path from the pipe joint section 115 to the pipe joint section 117 is substantially the same between the multiple air supply pipe sections 111 and 112 regardless of any of the plurality of intermediate air supply pipe sections 113.
Therefore, the flow of the heated air is restricted to a specific intermediate air supply pipe section 11.
No short circuit occurs at 3 and the air flows from the multiple air supply pipes 111 to the respective intermediate air supply pipes 113 so as to flow almost uniformly, and merge at the other multiple air supply pipes 112, so that uneven distribution of heat hardly occurs.

Depending on the size of the water gap 114, some of the snowflakes S do not come into contact with the surfaces of the manifold air supply pipe sections 111, 112 or the intermediate air pipe section 113.
Although it may be possible to invade the air supply pipes 111 to 11
Since the connection of 3 is performed by the connection net 12,
The snowflakes S do not accumulate in the water passage gap 114, and no snow melting remains. Furthermore, even if there is a snowflake S reaching the upper surface of the roof R, the snowflake S is melted by the snowmelt flowing on the upper surface of the roof R.

In the process of passing through each of the snow melting panels 1, 1,..., The air that has consumed the heat energy by the above-mentioned melting is returned through the exhaust pipe 3 and once returned to the air tank 4.
, And sent to a combustion type heat exchanger 6 by a blower or an air compressor 5, and replenished with heat energy by the combustion type heat exchanger 6, and then sent again to each snow melting panel 1, 1,. Can be

Since the air has a significantly lower viscosity than hot water or the like, it can pass through each of the snow melting panels 1, 1,... At a high speed, so that the heat supplied from the combustion heat exchanger 6 Is transported to all the snow melting panels 1, 1,... In a short time. Therefore, uneven distribution of heat (temperature gradient) between the upstream side and the downstream side becomes small, and a substantially uniform snow melting effect can be obtained on the entire roof. Also for this,
Re-freezing of snowmelt water can also be effectively prevented.

Here, the snow once deposited on the roof or the ground is denatured due to an increase in density due to compression, freezing at night, and the like. Therefore, melting it requires enormous heat energy. In addition, since the snow melting panel 1 melts the snowflakes S before they are deposited, the heat energy consumption can be effectively reduced. Further, since the snow melting and melting panel 1 prevents the accumulation of snow itself, the heavy load on the house or the like due to the weight of the snow accumulated on the roof during heavy snowfall is eliminated, and heavy labor such as snow removal is performed. Can be eliminated, and accidents caused by falling snow and ice blocks from the roof can be prevented.

In the above-described embodiment, the case where the snow melting panel 1 is installed on the roof R of a house has been described. However, the snow melting panel 1 according to the present invention is similarly laid on a slope, a narrow alley, or the ground where no stepping is performed. Since it is possible, it is also useful as a means for preventing snow accumulation on these.

FIG. 8 shows an example of installation in a living alley G between adjacent houses H to prevent snow accumulation. In this example, the roof R of each house H is attached to the roof R of FIG.
In addition to installing the snow-melting panel 1 in the same manner as above, a net-like support 7 is erected between the roofs R of the houses H via appropriate hanging supports 8 and the like, and a required number of The snow melting panels 1 are installed and connected to each other.

In this way, it is possible not only to prevent snow on the roof R, but also to prevent the snowflakes falling from the sky to the living alley G between the houses H from reaching the ground surface before reaching the ground surface. Since the surface of the upper heat dissipating panel body 11 contacts and melts, it is possible to effectively prevent snow on the living alley G. Therefore, it is possible to eliminate the need for removing snow accumulated in the living alley G with a scoop or the like and carrying out snow removal and snow removal work such as transporting the snow melting device to an installation location or a specific snow storage space. In addition, since it is not installed directly on the ground but is installed between the roofs R, the traffic of the living alley G is not hindered.

In this case, the snow melting panel group installed on the roof R and the snow melting panel group installed on the net-like support 7 between the roofs R can be connected to each other.
The net-like support 7 is connected to the connecting net 1 shown in FIG.
2, each air supply pipe section 11 in the heat dissipation panel body 11
Since it has a function of fixing 1-113, the connecting net 1
2 can be eliminated.

The connecting means between the intermediate air supply pipe portions 113 in the heat radiating panel main body 11 may be a wire, a synthetic resin fiber or the like, and is not particularly limited as long as it has a string shape or a net shape. Further, in the case of installation on the ground or the like, a running water space is secured between the heat dissipation panel main body 11 and the unevenness of the ground surface, so that the short leg 13 is unnecessary.

The connection form of the snow melting panel 1 is not limited to those shown in FIGS. 5 and 6.
They are connected in various forms depending on the area and shape of the snow-prevention target surface such as a roof.

[0045]

There is no danger of sliding down snow masses, such as when melting snow on the roof. In addition, since it can be used as a means for preventing snow accumulation on the roof of a house, a garden, an alley, a vinyl house for agriculture, and the like, it is possible to eliminate snow removal and snow removal work.

Further, since the heating gas passing through the air supply pipe section of the radiator panel body has a small viscosity, heat energy can be quickly spread to the entire snow melting panel, and a uniform snow melting effect can be obtained, and the accumulated snow can be melted. In this case, the energy consumption can be significantly reduced as compared with the case where the power consumption is reduced.

In addition, unlike installations that melt snow using hot spring water, groundwater, or seawater, installation conditions and areas are not limited, and heated air can be used as a heating medium. As the supply means, general-purpose inexpensive means can be used, and the entire equipment can be simplified.

It can be carried out easily and quickly, and because of its thinness, the snowflakes in contact with the surface can be efficiently melted.

According to the third aspect of the present invention, since a plurality of heat dissipating panel bodies can be connected via the pipe joint, a required number of snow melting and melting panels are connected in accordance with the area and shape of the surface to be prevented from snow accumulation. Can be laid so as to cover the entire surface to be snow-covered.

According to the fourth aspect of the present invention, the pipe joints are provided at both ends of the upstream air supply pipe section and both ends of the downstream air supply pipe section. Since the internal passage of the pipe joint located at the opposite end is closed, the direction of the snow melting panel flow path can be set as required, so that the connection form of the snow melting panel can be easily selected. it can.

According to the fifth aspect of the present invention, since the water gap is formed between the respective intermediate air supply pipe portions of the radiator panel main body, the water in which the snowfall pieces are melted on the surface of the air supply pipe portion is used to prevent snow accumulation. Can be quickly flushed over the surface.

According to the sixth aspect of the present invention, since the respective intermediate air supply pipe sections in the heat dissipation panel main body are connected to each other by the net, the string or the filament, the respective heat supply panel main bodies are connected by connecting the respective intermediate air supply pipe sections. Is prevented, and the dripping of snowmelt in the water gap between the intermediate air supply pipe portions is not hindered, and the generation of snowmelt residue due to snowflakes entering the water gap between the air supply pipes is also prevented.

According to the seventh aspect of the present invention, since the heat radiation panel body is laid on the snow-prevention target surface so as to float through the plurality of support legs, a gap is formed between the heat-dissipation target surface and the snow-prevention target surface. Since it is formed, the snow-melting water that has fallen from the surface of the air supply pipe portion is quickly discharged from the snow-prevention target surface.
