The present invention relates to a heating device, more particular to a heating device using a heater coil with convective heat as well as radiant heat of the heater coil, capable of preventing a fire accident by insulating the heater coil from the outside in case of an emergency. The heating device using a heater coil according to the present invention comprises a coil support drum which has the heater coil mounted on the peripheral surface thereof to support the heater coil; a radiant heat drum which is fastened in the rear end of the coil support drum; an upper head which is arranged in the rear end of the radiant heat drum and has an external air inlet formed on the rear surface thereof to inhale external air; and an insulation drum which has the front end and the rear end formed in the opened cylindrical shape, is contained inside the upper head and is mounted to be moved to the front of the upper head; a radiant heat plate which is connected to the radiant heat drum, is mounted in the state of being contained inside the insulation drum from the upper head and heats the external air inhaled from the external air inlet to convert to the warmth; an air blast fan which inhales the external air and emits the warmth to the front to blow the heat converted by more heating through the heater coil to the outside; an electric motor which is fastened with the air blast fan to provide torque; an elastic spring which move the insulation drum to the front to surround the radiant heat drum and the coil support drum; a safety wire which is arranged in the front side of the coil support drum to prevent a fire or a burn; an optical fiber which is arranged in the same shape as the safety wire and is mounted on the safety wire; and a safety switch which supplies a current to the optical fiber and initiates the movement operation of the elastic spring in case where an electric signal value of the optical fiber is changed by an external shock. |
