Description

  The present invention relates to a rain gutter freezing prevention device. More specifically, the present invention relates to a rain gutter freezing prevention device that is easy to construct and excellent in thermal efficiency.

When the rain gutter of a building such as a house is hit by a low temperature in winter, the water accumulated inside may freeze and cause damage due to expansion. In addition, an eaves column is also formed in the eaves wall, and there is a case where the weight is similarly damaged.
As a conventional rain gutter freezing prevention device, an apparatus that passes a heating wire through the inside of a pipe can be cited. This is because existing rain gutters can be used for easy installation, but depending on the shape of the gutter, it may not be possible to insert a heating wire, and as the heat generating part becomes longer, power consumption increases and thermal efficiency is good. I couldn't.

Here, for example, a gutter freezing prevention device shown in Patent Document 1 has been proposed. This rain gutter anti-freezing device includes an eaves cover that closes the upper opening of the eaves and convects warm air, a convection cover that primarily convects warm air inside the eaves cover, and the eaves It is composed of a vertical gutter that drains rainwater and a hot air generator that supplies warm air to the vertical gutter.
According to this rain gutter freezing prevention device, the cool air becomes warm air by passing through the hot air generating device, so that the vertical gutter is prevented from freezing and warm air also flows to the eaves through the vertical gutter.
