ABSTRACT:
An electric blanket used with a source voltage has a control device connected to the source voltage to control the source voltage in response to a predetermined temperature setting and a heating pad having a heating element arranged in the heating pad and connected to the output of the control device to generate heat. The heating element includes a first core, a first conductive element spirally wound around the first core, a second core arranged in surrounding relation to the first core and the first conductive element and a second conductive element spirally wound around the second core. The first ends of the first and second conductive elements are connected to the output of the control device and the second ends are connected to each other to define a conductive loop. The heating element further comprises an outer cover that covers the second core and the second conductive element and shields the internal components from external environment. The first conductive element comprises a third core and a conductive wire spirally wound around the third core. The conductive wire generates heat when electricity is applied.
