Abstract

PURPOSE: To facilitate the melting of snow at a relatively narrow area part by, after a panel having a stuck metal foil are spreadly provided on the grooved foam plastic sheet of piping as many as required, arranging the piping inside a gutter, and covering a water cut-off sheet on the piping and placing a walking gas-permeable mud wiping mat on it, and circulating hot water having specified temperature in the piping. CONSTITUTION: A metal foil 6 is covered on the grooved foam plastic sheet of piping 4 to uniform heat radiation from the piping 4. In addition, a water cut-off sheet 7 is covered the piping 4 to prevent melted water front staying around the piping 4 for checking the deprival of heat. In addition, a plastic gas permeable mud wiping mat 8 is placed to wipe a mud attaching to the bottom of a shoe during walking for smoothly radiating the heat of fusion of ice and snow. The size of a panel is decided to excellent working ability, and according to necessary area, the required number of sheets of panels are combined on the fitting part. The hot water of 20-70C is circulated in the piping inside a gutter to cause heat radiation for melting the snow.

Description

Detailed Description of the Invention

[0001]

[Industrial field of application] A device for melting snow on a pedestrian path in a relatively small area of a snowy area. When there is no snow, it can be disassembled into parts and stored.

[0002]

2. Description of the Related Art A conventional snow melting device is a method of burying a sheet of heating wire or a sheet heating element or a hot water circulation pipe in the ground, and in any case, it requires the installation of a specialized equipment supplier.
It was not something that the user could freely install and remove.
In the unpaved area, snow often becomes jammed or becomes soft ground, which makes walking difficult.
A new mud-wiping mat was installed at the entrance.

[0003]

[Problems to be Solved by the Invention] Not only paved land but also installed on uneven soil surface to provide a comfortable walking path even when snow melts, without polluting the entrance, unnecessary In this case, each part can be disassembled and stored, and the installation and storage work can be done easily even by a non-specialist.

[0004]

[Means for Solving the Problems]

-The material of the panel 3 with the groove 9 is the foamed plastic sheet 5 in which closed cells that do not absorb the melted water are used to reduce the weight and adapt to the unevenness of the installation surface.・ 5 to 1 to make the heat radiation from the pipe 4 uniform on the walking surface
A metal foil 6 having a thickness of 00 microns was covered. -A water blocking sheet 7 having a thickness of 0.1 to 5 mm is provided so that the melted water does not stay around the pipe and take away heat. -A plastic breathable mud-wiping mat 8 was provided to drop mud on the soles of shoes while walking and to smoothly radiate the melting heat of ice and snow. -The mud-wiping mat 8, the waterproof sheet 7 (may be laminated on the mud-wiping mat), the panel 3 with metal foil, and the piping material 4 can be disassembled and stored.・ Panel size is 0.5m x 1m, 1m x 1m, 1
The size is about m × 2 m with good workability, and the required number of sheets are combined with the concave and convex fitting portions 10 according to the required area.

[0005]

In the snow melting apparatus of the present invention having the cross-sectional structure as shown in FIG. 2, the heat source is a petroleum boiler (other than the boiler such as gas, rentane, district heating water, factory waste water, hot spring, etc.). It is possible to use kerosene from the oil storage tank 1 to the boiler 2 as shown in FIG.
The hot water is radiated while passing through the pipe connected to the grooved panel 3 to melt the snow. As shown in FIG. 3, for example, the combination panel has a circulating hot water inlet / outlet portion b and a circulating hot water turning portion c, and a required number of a portions are combined in the meantime. Piping 4 is performed according to the groove of the laid panel, a water blocking sheet 7 having a required area is covered thereon, and a breathable mud wiping mat 8 having the same area is laid on the sheet to complete the process.

[0006]

EXAMPLE A panel of FIG. 3, 9 m of 0.5 m × 1 m a part, 1 part of 0.5 m × 0.5 m b and c part were combined with 5 m ² of the snow melting device of the present invention. When hot water of 45 ° C was circulated at a speed of 1 m / sec in a pipe having a diameter of 12 mm and an inner diameter of 9 mm, a dry walkway was obtained without snowfall of 2 cm / hour. After 15 cm of snow had accumulated on the same equipment, hot water at 50 ° C. was circulated at a speed of 1 m / sec, and it completely melted in 90 minutes.

[0007]

EFFECTS OF THE INVENTION The snow melting device of the present invention can be applied to a place where it is difficult to install a conventional snow melting device such as a relatively small area of snow melting in a front yard of a general household, a parking lot, a short-term exhibition hall, etc. ， Everyone can easily install and melt snow (obtaining a very comfortable walking path and eliminating mud stains at building entrances etc.), and it can be easily and compactly stored when not needed.
