Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel snow melting method suitable for snow melting in a garden of a house or a private road.

[0002]

BACKGROUND ART AND PROBLEMS Snow removal countermeasures have become a major problem in heavy snowfall areas, and various snow melting devices have been proposed particularly for snow cover on the roof.

On the other hand, there is no effective snow removing means for removing new snow accumulated on the yard of a house or a private road or snow removed from the roof, and after all, it is manually carried to another place or removed. The reality is that you have to buy a machine to remove snow. However, after all, the snow blower only moves the snow to another place, and it cannot be used without a snow discharge place (vacant land), and it is expensive and inconvenient to be operated by a person.

[0004] In principle, the snow melting device for the roof has a structure in which the snow melting device is fixedly installed on the roof or the roof is constituted by the snow melting device itself, so that the construction work is difficult and costly, and the removal is also difficult. Since it cannot be done, there is a problem that rust or the like is generated and the device is significantly deteriorated during a period such as summer when there is no snowfall.

The present invention solves the problems existing in the background art as described above, and it is possible to freely and easily perform snow melting by freely selecting an arbitrary snow melting place such as a garden or a private road, and a roof. It is an object of the present invention to provide a snow melting method that can easily perform snow melting even on snow accumulated on the ground.

[0006]

A snow melting method according to the present invention is a flexible method having a heat medium flow passage 2 inside and a heat medium supply port 4 and a discharge port 5 at both ends of the flow passage 2. The sheet-shaped snow-melting mat 1 is laid in a snow-melting place such as a garden of a house or a private road to melt snow during snow-melting.
It is characterized by being removed from the snow melting place.

[0007]

According to the snow melting method of the present invention, the snow melting mat 1
Since it is a flexible sheet, it can be laid as it is on the private road 33 such as in front of the entrance 31 or in front of the garage or under the eaves 32 as shown in FIG. As shown in FIG. 4, the supply port 4 and the discharge port 5 of the snow melting mat 1 are provided with a warm water feed pipe 23 and a return pipe 24 of a warm water (antifreeze and antifreeze mixed water) supply system 20 including a water pump 21, a boiler 22 and the like. Are connected to each other, and the heat medium which is always warmed is circulated in the flow path 2. As a result, the snow melting mat 1 is warmed up, and the fresh snow accumulated on it or the snow S (FIG. 6) dropped from the roof is melted.
That is, the snow melting action is performed.

Since the snow melting mat 1 is in the form of a flexible sheet, it can be rolled and stored in a roll when the snow is not melted.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

First, the structure of the snow melting mat 1 used in the snow melting method according to the present invention will be described with reference to FIGS. 4 and 5.

The snow melting mat 1 is provided with a mat body 3 which further comprises a rectangular sheet collecting pipe portion 10 and header portions 11 and 12 integrally formed at both ends thereof. Collection part 10
Has a large number of linear flow paths 2 formed in parallel inside a sheet member having a constant thickness, and both ends of the flow path 2 communicate with the header portions 11 and 12. On the other hand, the header part 11 on the water supply side
Is a water supply chamber 1 which is integrally provided with a cylindrical supply port 4 at one end thereof.
The warmed antifreeze liquid or the antifreeze liquid mixed water (hereinafter, referred to as hot water) that forms the water flow source 3 and flows from the supply port 4 is supplied to the water supply chamber 13.
Then, a uniform amount of hot water is supplied to each flow path 2. On the other hand, the header section 12 on the drain side is also formed in the same shape as the header section 11, and a drain chamber facing the rear end of each flow path 2 is formed inside. The cylindrical discharge port 5 is formed on the opposite side of the supply port 4. These collecting section 10, header section 11, 1
2, the supply port 4 and the discharge port 5 are integrally molded of, for example, EPDM synthetic rubber. As a forming material, select a flexible material having excellent corrosion resistance, heat resistance, weather resistance, strength, and the like. In addition, by appropriately selecting the thickness of the sheet member, the size of the flow path 2, the thickness of the partition wall between the flow paths 2 and 2, and the thickness between the flow path 2 and the upper surface 3a, for example, the mat body 3
The flow path 2 does not collapse even if a car or the like rides on it. As shown in FIG. 5, the mat body 3 has a flat lower surface and a corrugated upper surface 3a along the circumferential shape of the flow passage 2 having a circular cross section to prevent slippage, and further to discharge snowmelt water. It has a gutter function that makes the unidirectional. Although the mat body 3 is integrally formed of the same material, it may have a two-layer structure in which a flexible heat insulating sheet is attached to the lower surface. It should be noted that the average snow melting capacity of 6.5 cm / hour was obtained at a flow channel diameter of 5 mm, a flow channel pitch of 6.2 mm, and a hot water temperature of 25 ° C.

On the other hand, a hot water supply system 20 is connected to the snow melting mat 1. That is, the hot water sending side pipe 23 is connected to the supply port 4, and the return side pipe 2 is connected to the discharge port 5.
4, and a water feed pump 21 and a boiler 22 are connected between the pipes 23 and 24 to form a closed loop circulation path. As shown in FIG. 2, the hot water supply system 20 is a carriage 26 movable by casters 25, 25.
In addition, a water supply pump 21, a boiler 22, a high tank 27 containing antifreeze liquid or antifreeze liquid mixed water, a coupling pipe 28, and the like may be mounted.

The hot water supply system 20 may be provided with other necessary auxiliary devices such as a thermometer for displaying the circulating hot water temperature and a moving handle. Further, the hot water supply system 20 may be configured as a unit that is movable in this way, or may be a stationary type that is fixed to a house or the like. Furthermore, an existing boiler or pump installed in a house or the like may be used.

Next, a method of using the snow melting mat 1 including the snow melting method according to the present invention will be described with reference to the drawings.

First, since the snow melting mat 1 is a flexible sheet, it can be rolled into a roll shape when not in use, that is, when it is not snow melting, and can be stored in a predetermined storage place other than the snow melting place (see FIG. 3). In this case, since the snow melting mat 1 is rolled into a roll shape, a relatively small storage space is sufficient.

On the other hand, when the snow-melting mat 1 is used, that is, when the snow-melting mat 1 is used, as shown in FIG. 1, the snow-melting mat 1 has a passage 35 from the front of the entrance 31 to the gate 34 in the house M, or under the eaves 32.
It is used by laying it on private road 33. Further, although not shown, it can be freely installed in other places such as a garden from a garage to a public road, a roof, and even a school or a hospital. This ensures passage even when heavy snowfall occurs at night, etc., and is particularly significant in public facilities. In addition, FIG.
If the roof R of the house M is formed to have a steep slope as described above, and the snow S on the roof is dropped on the main snow melting mat 1 under the eaves 32 at any time, a snow melting device on the roof can be provided as in the conventional case. It is possible to melt roof snow easily and efficiently without using it. Thus, the snow melting mat 1 can be carried and used for arbitrary snow melting places.

In this case, the snow melting mat 1 is used by being connected to a hot water supply system 20, as shown in FIG. In the system 20, the antifreeze liquid or the unequal liquid mixed water is warmed by the boiler 22 and becomes hot water.
1 by the supply port 4 and the header portion 1 in the snow melting mat 1
It is supplied to each of the flow paths 2 through the first water supply chamber 13. Then, heat exchange with the snow is performed on the mat body 3, and the cooled hot water passes through the drainage chamber of the header portion 12 and the discharge port 5, and then to the boiler 2
Returned to 2.

If a heat storage tank is connected instead of the boiler 22, the solar system can be used as it is. In this case, it is possible to select a place where the sunlight is irradiated for the longest time and install it in any place.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments. For example, the flow path 2 in the mat body 3 may be formed in one zigzag-shaped flow path without using the header portion. Other detailed configurations, shapes, arrangements, materials and the like can be arbitrarily modified and implemented without departing from the spirit of the present invention.

[0020]

As described above, the snow melting method according to the present invention has a flexible sheet-shaped snow melting mat having a heat medium flow passage inside and having heat medium supply ports and heat medium discharge ports at both ends of the flow channel. When the snow is melted, it is laid in a snow melting place such as a garden of a house or a private road to melt the snow, and when the snow is not melted, it is removed from the snow melting place.

Conventionally, it is possible to easily and easily remove snow from a garden or a private road, which has been performed manually or with an expensive snow remover, and unmanned snow can be melted even during the daytime, especially at night. Therefore, the profit is large in public facilities.

The snow melting mat is extremely easy to handle, and it can be used only by carrying it to an arbitrary place where the snow is to be melted and laying it. Therefore, no operation like a snow blower is required, and women and the elderly can easily remove snow.
It is easy to use and can significantly improve snow melting efficiency.

When the snow-melting mat is moved or when it is not used in summer, if it is rolled and rolled into a roll shape, it can be easily moved, and the storage space for storage is small.

The snow on the roof can also be melted on the ground by combining the snow melting mat and the roof shape.
An epoch-making snow-melting system can be constructed to replace the conventional snow-melting device on the roof, and implementation costs are almost unnecessary.
