Abstract

PURPOSE:To enhance the handleability of a heating apparatus by reducing the connection of a controller to a bracket main body to at least a power cable. CONSTITUTION:Data about e.g. set temperature controlled by a control portion 13 are modulated by a converting portion 12 into high frequencies, which are in turn superimposed on the power waves of a power cable 18. The demodulating portion 17 of a heating apparatus main body 11 demodulates the high frequencies superimposed on the power waves and transfers them to an output adjusting portion 16 and the amount of power supplied to a heater wire 14 is adjusted by the output adjusting portion 16 in accordance with the set temperature.

Therefore, the handling of the controller 1 is inconvenient. Therefore, an object of the present invention is to provide a heating device in which the connection between the controller and the blanket body is reduced to at least the power line to improve the handling.
