Description

  The present invention relates to an energy-saving roof electric snow melting method that can easily make an existing roof an energy-saving snow melting roof at low cost.

  Conventionally, metal steel plates are mainly used on the roofs of houses in the snowfall region to lighten the whole. As for the shape, the horizontal method and the vertical brick method are often used. As a method of melting snow on these roofs, pipes are laid at regular intervals on the roof surface, and anti-freezing liquid heated by using a boiler is circulated in the pipes to melt snow.

  However, in such a snow melting method, the distance between the boiler installed on the ground and the roof is long, and the distance between the circulation pipes attached to the roof is also long, so the temperature of the heated antifreeze liquid is circulated in the pipe. 70% will be lost. For this reason, it was necessary to operate the boiler all day to keep the temperature of the antifreeze.

  The problem to be solved is a roof snow melting device with low heat loss and high thermal efficiency, which has a beautiful appearance and can be installed on an existing roof at a low cost, and its snow melting method. The purpose is to provide a roof.

  In order to achieve the above-mentioned object, the snow melting roof construction method according to the present invention is a method in which an existing roof is coated with a heat insulating material, and a linear heating element is laid on the roof in a meandering manner at regular intervals. It is a protective cover of the same shape and color as the roof, and the upper surface of the existing roof is covered with a carbon powder coated on the back surface.

  Further, the snow melting roof according to the present invention is a snow melting roof constructed by the above-mentioned method, and the top surface of the roof is coated with a heat insulating material, and linear heating elements are laid in a meandering manner at regular intervals on the roof. A protective cover having the same shape and color as the existing roof, the back surface of which is coated with carbon powder, and the upper surface of the existing roof is covered.

  According to the construction method of the snow melting roof of the present invention, a linear heating element is laid on the roof top surface coated with a heat insulating material, and the roof is covered with a protective cover whose back surface is coated with carbon powder. It is possible to make the roof a snow melting roof easily and inexpensively, and it is possible to provide a snow melting roof with higher thermal efficiency without impairing the appearance.

  In addition, the snow melting roof according to the construction method of the present invention protects the linear heating element by the protective cover and prevents a failure such as disconnection, and the thermal efficiency by the effect of far infrared rays generated from the carbon powder coated on the protective cover. High snow melting is possible.

  For the purpose of making the existing roof an easy and inexpensive snow melting roof with high thermal efficiency, after coating the existing roof with a heat insulating material, and laying linear heating elements on the roof in a meandering manner at regular intervals, It was realized by covering the top of the roof with a protective cover of the same shape and color as the existing roof, with the back side coated with carbon powder.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a partially cutaway perspective view showing an embodiment of a snow melting roof according to the present invention, FIG. 2 is a cross-sectional view of the snow melting roof of FIG. 1, and FIG. 3 lays a linear heating element on the existing roof. It is the perspective view which showed the state which carried out.

  In the snow melting roof according to the present invention, after the insulating roof 4 is coated on the existing roof 1, the linear heating element 2 is preferably laid on the existing roof 1 in a meandering manner, preferably an electric heater. In addition, the existing roof 1 is covered with a protective cover 3.

  Considering the construction of various existing roof shapes as the heat insulating material 4, a paint type heat insulating material such as silicone resin is most suitable. By applying this heat insulating material 4 on the roof 1, the roof 1 As a result, the heat loss generated from the linear heating element 2 can be reduced. In addition, according to the shape of a roof, you may use not only a paint type heat insulating material but a sheet-like heat insulating material.

  The surface of the protective cover 3 has the same color and shape as the existing roof, and the back surface is coated with carbon powder 5. Therefore, the protective cover 3 protects the linear heating element 2 and heat generated from the linear heating element 2 is transmitted to the carbon powder 5 on the back surface, thereby generating a large amount of far infrared rays. Since this far infrared rays increase the thermal energy by generating molecular vibrations with each other, it is possible to melt snow more efficiently than snow melting that relies on temperature alone. Further, since the protective cover 3 has the same color and shape as the existing roof 1, it does not impair the aesthetic appearance.

  As a method of melting snow, first, the linear heating element 2 is energized to radiate heat, and when the radiated heat is transmitted to the carbon powder 5 applied to the protective cover 3, far infrared rays are generated. This far-infrared ray penetrates directly into snow and ice and acts on the molecule to promote molecular vibration. Snow melting is performed by converting this molecular vibration into thermal energy. The far-infrared snow melting has far less heat loss because the far-infrared radiation directly acts on snow and ice, and the heat efficiency is extremely high compared to the snow melting only by heat generation. Therefore, it is possible to melt snow with power consumption of about one-third compared to snow melting only by heat of the heating element.

  In the present embodiment, the existing roof 1 is a flat roof, but the present invention can be implemented in various roofs. For example, in the case of a rod roof, the linear heating element 2 may be arranged in a meandering manner along the rod portion and then covered with the protective cover 3.

  Further, the linear heating element 2 is provided with a control unit, and various sensors such as a temperature sensor and a snowfall sensor are attached to the snow melting roof of the present invention, and the linear line is formed by the control unit based on detection information of these sensors. If it is set as the structure which controls the electricity supply to the heat generating body 2, more efficient snow melting will be attained.

  The present invention is not limited to the above embodiment, and the protective cover is constructed according to the shape and color of the existing roof, so it can be constructed easily and inexpensively even for various existing roofs. In addition, it is possible to provide a snowmelt roof having high thermal efficiency.

It is the partially cutaway perspective view which showed one Example of the snow melting roof of this invention. It is sectional drawing of the snow melting roof of FIG. It is the perspective view which showed the state which laid the linear heating element on the existing roof.
