However, there is a problem that the insulation is broken to cause insulation deterioration. An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a snow melting apparatus having a structure in which an electrical connection between heat generating panels is not damaged by external factors such as stabs such as disconnection or insulation failure. .

[0004]

In order to solve the above-mentioned conventional problems, a snow melting apparatus according to the present invention is characterized in that at least two or more heating panels including an electric heater and an induction heating coil are arranged on the surface of the ground, In a snow melting apparatus that melts snow falling on the surface, a connection box including a connection portion for electrically connecting an electric heater or an induction heating coil of the adjacent heat generating panel is included, and the connection portion is pierced from the outside. The configuration is such that there is no damage such as disconnection or insulation failure.

DETAILED DESCRIPTION OF THE INVENTION According to the first aspect of the present invention, there is provided a snow melting apparatus for arranging at least two or more heat generating panels including an electric heater and an induction heating coil on the ground surface and melting snow falling on the heat generating panels. In the above, by having a connection box that includes a connection portion for electrically connecting the electric heater and the induction heating coil of the adjacent heating panel, the connection portion for receiving piercing and the like from the outside in the connection box There is no damage such as disconnection or insulation failure.

According to a second aspect of the present invention, the connection box according to the first aspect is formed integrally with the heat generating panel.
The connecting operation of the heat-generating panels is easier than in the case where the connection box is a separate body, and the connecting portion can be configured robustly.

According to a third aspect of the present invention, the connection between the heat generating panels can be strengthened by fixing one end of the connection box to the adjacent heat generating panel. In addition, the distance between the heat-generating panels does not increase due to the pulling force of the heat-generating panels in the lateral direction, and no tensile stress is applied to the electrical connection portions, so that a durable and long-lasting snow melting device can be realized.

According to a fourth aspect of the present invention, the connecting portions of the first to third aspects connect the connection terminals provided on the adjacent heat-generating panels with a connection plate such as a copper plate. The connection work is easier than the connection using electric wires, and the connection portion can be thinly and robustly realized.

[0009]

FIG. 2 is a view for explaining the overall arrangement of a snow melting apparatus according to the present invention. A plurality of heating panels 13 are arranged in a parking space at the entrance. The heat generating panel 13 has a power supply 1
4 through a power cable 15. As a result, the entire heat-generating panel generates heat, and the snow falling on the heat-generating panel can be melted.

FIGS. 1A and 1B are views showing the structure of a connection portion of a heat generating panel according to the present invention, wherein FIG. 1A is a top view and FIG.
An electric heater A2 and an electric heater B7 are built in the heat-generating panels A1 and B6, respectively. Electric heater A2 and electric heater B7 are connected to electric wire A8 and electric wire B, respectively.
9 in parallel. Wire A8 is connection terminal A3
In addition, the electric wire B9 is connected to the connection terminal B5. One end of the connection box bottom 10 is integrated with the heat generation panel B6, and the other end fits into a recess provided in the heat generation panel A1. Then, the connection box bottom 10 and the heat generating panel A1 are fixed by the connecting structure 4 with screws.
Reference numeral 13 denotes an electrical connection plate made of a copper plate, and a connection terminal A
3 and the connection terminal B5. A connection box cover 11 covers the connection terminal A3 and the entire connection box bottom 10.

As described above, the connection box 12 composed of the connection box bottom 10 and the connection box cover 11 keeps insulation from the outside and protects the connection portion by receiving disturbance such as piercing from the outside. Also, the heat generating panel A1 is formed by the screw fixing structure 4.
And the heat generation panel B6 are connected and fixed, so that the distance between the heat generation panels does not increase due to the lateral pulling force generated when the vehicle stops on the heat generation panel,
Electrical connection points, ie, connection terminal A3 and connection terminal B5
No tensile stress is applied.

In addition, the electrical connection between the connection terminal A3 and the connection terminal B5 by the connection plate 13 can be easily performed by screwing, and the connection plate 13 made of a copper plate can be easily thinned as compared with the case where it is connected by electric wires. Is possible. Therefore, since the heat-generating panel can be realized in a thin shape, even if the heat-generating panel is installed on the ground, it does not cause discomfort or hinder the passage.

[0013]

As described above, according to the first to third aspects of the present invention, the electrical connection between the heat-generating panels is easy and the electrical connection portion is robust against disturbance such as piercing. be able to.

According to the fourth aspect of the present invention, a robust and thin electrical connection structure can be realized.
Therefore, a thin heating panel can be formed.
