PURPOSE: A snow melting system is provided to prevent accumulated snow from freezing by applying heat to a mat using a hot wire. CONSTITUTION: A snow melting system(100) comprises a mat(130-1,130-2,130-3,130-4,130-5,130-6), a hot wire, and a sensor. The mat can be divided into six portions and be folded along the divided lines. The hot wire applies heat to the mat. The sensor senses a snowfall. When the sensor senses the snowfall, currents are applied to the hot wire. |
