Abstract
PURPOSE: To get comfortable heating by the forced circulation of warm air generated by warm air generating unit installed at inside of wooden frame of foot warmer and generating warm air through self heat generating positive characteristic thermistor which is ventilated forcibly.
CONSTITUTION: When electric power is supplied, positive characteristic thermistor group 3 bigin to generate heat and electric motor 15 bigins to drive ventilating fan to ventilate thermistor group 3, then the temperature inside of the wooden frame rises gradually. When the predetermined temperature is attained, low temperature thermostat is activated and reduces the quantity of heat generation of positive characteristic thermistor element 3' by the low temterature control circuit 14. However, other positive characteristic thermistor element 3' in the high temperature control circuit 11 continues to generate heat and the temperature inside of foot warmer 1 is raised. When the predetermined temperature of the air inside of foot warmer is attained, positive characteristic thermistor element 3' of high temperature control circuit 11 stops to generate heat, however, the power is supplied to low temperature control circuit 14 during this period and keep the comfortable temperature inside of foot warmer. When the temperature of the air inside of foot warmer is lowered, the high temperature thermostat is activated and repeat this operation.
