Abstract

PURPOSE:To prevent the occurrence of an icicle by installing a panel heater having a circular arc-shaped tip portion on the eaves tip of a roof. CONSTITUTION:A panel heater 4 having a circular arc-shaped tip portion is installed on the eaves tip of the roof 2 of a house 1. The snow accumulated on the roof 2 slides down from the circular arc-shaped tip portion of the panel heater 4. The water generated when snow is heated by the panel heater 4 drops in no contact with a cornice.

Description

DETAILED DESCRIPTION OF THE INVENTION (Prior Art) First, the phenomenon of icicle formation will be explained with reference to the schematic diagrams of the upper part of a house shown in FIGS. 7 and 8. , snow eaves 11A are formed at the eaves due to the influence of the wind, the weight of snow, etc. as shown by the arrows. In addition, 1
2 indicates the gutter.

On the other hand, indoor heating, solar heat, a roof snow melting heater, etc. melt the snow 11 on the roof 10 and turn it into water. This water flows in the direction of the snow eaves 11A hanging down from the eaves as shown by the dotted line in Figure 8, and when it touches the snow eaves at the eaves, the temperature reaches 0°C, and just before it turns into water droplets and falls, the outside temperature drops to 15'C. If so, it will freeze and create icicles IIB.

Then, when the icicles IIB that appeared on the eaves fall,
In addition to causing personal injury, icicles can also cause damming up of melted water that enters the attic through the roof joints and even enters the room, staining the ceilings and walls. phenomena may also occur.

In order to prevent such problems from occurring, it is best to prevent snow eaves from hanging over the eaves as shown in Figure 9. Although this fact was already known, a device to prevent icicles from forming on eaves had not yet been developed.

(Problems to be Solved by the Invention) The purpose of the present invention is to prevent snow eaves from forming on the eaves of the eaves to prevent icicles from forming on the eaves of the roof, and to eliminate personal accidents and "glare leaks" caused by falling icicles. .

(Means for Solving the Problems) The first gist of the present invention is that a panel heater having an arcuate tip portion is installed on the eaves of a roof.

The second aspect of the present invention is that a panel heater having an arcuate tip portion is superimposed on the eaves of a roof on which a snow melting heater is installed.

Furthermore, the third gist of the present invention is that a panel having an arcuate tip portion is superimposed on the eaves where the snow melting heater is installed.

(Function) Since a panel heater or panel with an arc-shaped tip is installed at the eaves of the roof, snow will not slide down from the arc-shaped tip and create a snow eave. Therefore, indoor heating, panel heaters, snow melting When water melted by heater heating, solar heat, etc. falls, it does not touch the snow canopy, so icicles do not form.

(Example) Regarding the example of the present invention, with reference to FIGS. 1 to 6,
This will be explained below.

Figure 1 is a schematic diagram of the upper part of the house, including the roof covered with snow.
The soil is a house, 2 is a roof, and 3 is fallen snow. 4 is a panel heater with an arc-shaped tip, for example, as shown in the perspective view of Figure 2, and the heat dissipation part is a panel heater. A heating device with a surface heating element 7 (Fig. 3) installed inside a heat sink sealed by an exterior material is used. Therefore, heat is radiated from the upper and lower exterior materials. Note that 6 indicates a gutter.

The dotted line indicates the flow of melted water heated by the panel heater 4 or the like. In this embodiment, the panel heater 4 having an arcuate tip portion does not form a snow eave as shown in the figure, so that melted water does not touch the snow eave and freeze to form icicles.

Figure 4, like Figure 1, is a schematic diagram showing the upper part of the house including the snow-covered roof, where the soil is the house, 2 is the roof, 3 is the fallen snow, 4 is the panel heater, and 5 is the roof. Each installed snow melting heater is shown.

FIG. 5 shows a perspective view of the icicle prevention device shown in FIG. 4 applied to a tile-and-stick roof.

In this embodiment as well, the panel heater 4 having an arcuate tip portion prevents the formation of snow eaves, and therefore the melted water flowing as shown by the dotted line falls without touching the snow eaves, so icicles are not formed.

Furthermore, FIG. 6 shows a configuration in which the panel heater 4 shown in FIG. 4 is replaced with a panel 4°. In this embodiment, the snow 3 on the roof 2 easily gets soaked at the 4° arcuate tip of the panel.
Moreover, in this area, the snow does not melt and water droplets do not form, so no eaves can be formed.Therefore, the running water melted by the snow melting heater 5 falls without touching the eaves as shown by the dotted line, so icicles are almost never formed. .

However, in early spring, when the temperature drops at night, the water melted by the sun's heat may form some icicles on the arc-shaped tip because it is only panel 4'', but it is better than when snow melting heater 5 is used only. The generation of creeping icicles is small, and since it does not use a panel heater, it has the advantage of being low cost.

By the way, the radius of the arc-shaped tip of the panel heater or panel described above is increased to about 100 to 200 m/ra so that a gutter exists inside it, and the exterior plate or panel of the panel heater is made to have a slippery surface. It goes without saying that you should select the metal plate, plastic plate, etc. that you have.

(Effects of the Invention) As can be understood from the above explanation, according to the present invention, since a panel heater or a panel having an arcuate tip portion is installed at the eaves, no snow eaves are created, and therefore indoor heating, etc. Icicles do not form because the melted water falls without touching the snow canopy.

Therefore, accidents such as personal injury caused by falling icicles and
This has the advantage of preventing stains on the ceiling and walls.
