Abstract

PURPOSE: To attempt to save energy of the foot warmer and to improve the safety thereof by providing a control circuit controlling to slightly lower the temperature within the foot warmer when a heater of the foot warmer produces a predetermined output which is reduced from the rated output thereof or the foot warmer keeps a predetermined temperature for a predetermined period of time.
CONSTITUTION: When power is supplied to a heater 1 of the foot warmer, the temperature of the foot warmer rises and reaches a set value in a short period of time. At the same time, the output of the heater is gradually reduced to a low output. Furthermore, whether he temperature within the foot warmer or the output condition of the heater 1 holds a predetermined value or a predetermined output value reduced from the rated output or is under a varied unstable condition, is judged by a control process such as the temperature check of a control unit having a control circuit 10 within an external controller 9 or the secondary side voltage check of a current transformer. For example, when the output of the heater is of an output value reduced from the rated output of the heater or the condition of the temperature within the foot warmer is constant for a predetermined period of time, such a temperature control in performed as lowering it to a value which is slightly lower than the originally set temperature.
