[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a snow melting device that melts snow using hot air generated by combustion or the like.
[0002]
[Prior art]
Conventionally, as this type of snow melting device, for example, there is one described in JP-A-2-300402. FIG. 12 is a block diagram showing this conventional snow melting apparatus.
The hot air generated by the hot air generating means 100 passes through the pipe 101 and is sent to the hot air inlet 104 of the snow melting flat body 103 by the air blowing means 102. In the snow melting flat body 103, a circulating pipe 105 for circulating hot air is embedded in a material such as asphalt. When the hot air passes through the circulating pipe 105, the heat of the hot air is transmitted to the snow melting flat body 103 to melt the snow 106 placed on the snow melting flat body 103.
[0003]
[Problems to be solved by the invention]
However, in the conventional snow melting apparatus, the size of the snow melting flat body 103 differs depending on the installation location, so that it is necessary to make a different snow melting flat body 103 for each installation. For this reason, the shape of the reflux pipe 105 needs to be made every time it is installed so as to cover the entire surface of the installation place without crossing, and there is a problem that the number of installation steps increases, It takes time for the transmission to reach the snow 106 on the upper part of the snow melting plane 103 from the cross section of the circulating pipe 105 through the asphalt of the snow melting plane 103, and workability during construction of the snow melting plane 103. In addition, there is a problem in that a product having both excellent strength of the completed snow-melting flat body 103 and heat transfer characteristics in which the supplied heat is effectively transferred to the snow cannot be obtained.
