HEATER FOR ELECTRIC BLANKET

摘要

An electric blanket (11) connectable to a power source is provided. The electric blanket includes first and second heating wires (14 and 16) connected in series and a monitoring wire (18) positioned therebetween. The monitoring wire (18) is engageable with at least one of the heating wires in response to a predetermined temperature. A cutout (20) interconnects the heating wires (14 and 16) to a power source. A monitoring circuit triggers the cutout (20) so as to disconnect the heating wires (14 and 16) from the power source in response to engagement of the monitoring wire (18) with one of the heating wires (14 and 16).
