Safety energy-saving constant-temperature electric heating carpet

The utility model discloses a safety energy-saving constant-temperature electric heating carpet which consists of a fusing device, a power switch, a timer, a alternative-currency contact device, a heating transformer and combined carpet elements; the combined carpet elements consist of a ordinary carpet and a heating pad. The ordinary carpet covers the heating pad so that the safety energy-saving constant-temperature electric heating carpet can be easily cleaned. The heating pad consists of an insulation layer of far-infrared paint, an electric heating layer and a heat-insulation layer. The heating voltage does not exceed 30 volts. Therefore, electricity leakage of the electric heating pad does not lead to any hurt on people; the adjustable timer can realize the constant temperature; the far-infrared paint achieves the energy saving. The utility model is low in cost and easy in manufacturing. The utility model is practical, and is an ideal electric heating apparatus.
