Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a roof 1. :Related to a roof snow removal device that removes accumulated snow by cutting it and letting it fall.

[Conventional technology and its problems]

Conventionally, a snow melting method is known as a roof snow removal device. This snow melting method is broadly divided into hot air, hot water, and electric heating methods. As known from Japanese Patent Application Laid-open No. 60-30754, the hot air type melts snow by guiding hot air generated by a hot air generator onto the roof. The disadvantage is that sometimes a large amount of thermal energy is required. Also, warm air tends to cause condensation in the attic. On the other hand, the hot water type, for example, as known in Japanese Utility Model Application Publication No. 57-97025, hot water from a boiler or ground water is guided onto the roof. However, since it uses water, it is prone to corrosion and shortens the lifespan of buildings. There is also an ode to ground subsidence when using groundwater. Furthermore, in the thermal method, the equipment itself is expensive because the heater is complicated.

As mentioned above, conventional snow melting equipment requires a large amount of energy to remove snow, has high running costs, and the equipment itself is large and expensive.

A known method for removing snow without using energy is to increase the slope of the roof and allow the snow to fall naturally, but this requires a thicker roof slope, which results in a shoddy internal structure of the house. Furthermore, there is a drawback that the snow removal effect is low when it comes to sticky snow.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a snow removal device that reduces the energy required for snow removal and reliably removes snow by cutting and removing snow.
