Abstract
The application provides a far-infrared electric heating plate, which comprises a power input line, a heating plate body and a metal sheet. The power input line comprises a live wire, a zero wire and a ground wire. The heating plate body comprises a first insulating plate, a second insulating plate, an electric heating wire, a first conductive sheet and a second conductive sheet. The first insulating plate is provided with a wiring hole. The electric heating wire, the first conductive sheet and the second conductive sheet are located between the first insulating plate and the second insulating plate. One end of the electric heating wire is electrically connected with the first conductive sheet. The other end of the electric heating wire is electrically connected with the second conductive sheet. The first conductive sheet is electrically connected with the zero wire. The second conductive sheet is electrically connected with the live wire. The metal sheet is arranged on the side of the second insulating plate away from the first insulating plate. The metal sheet is electrically connected with the ground wire. The second insulating plate is provided with the metal sheet for ground protection. The power input line is provided with the ground wire connected with the metal sheet. When the external insulating plate is damaged, the use safety of the product can be improved.
