Description

TECHNICAL FIELD The present invention relates to a snow melting device that melts snowfall or snowfall on a roof of a building in a snowy area in the winter season or the like using hot air generated by combustion or the like.

Conventionally, as a snow melting device using hot air, there is a method of embedding a metal pipe in asphalt, passing the hot air, and melting snow on the asphalt by heat transfer. In addition, using a concrete block with a through hole between two opposing surfaces, the through holes are connected so as to form a hot air passage, and when the hot air is passed, There are a method of melting snow and a method of melting the snow by blowing a hot air directly from the through hole at the same time as the heat transfer and providing a passage on the surface of the concrete block. However, these conventional snow melting devices are heavy and expensive to manufacture because they use metal pipes and concrete blocks for the snow melting body. It has a problem that it is discharged as it is and energy is wasted.
