PURPOSE:To improve the flow of air with respect to a heater and compact an exothermal body unit by a method wherein the infrared rays heater is arranged near a motor so as to be in the same plane of the motor and a fan is rotated at the upper side of both of the motor and the infrared rays heater. CONSTITUTION:The motor 4 is arranged at the center of a guard 1 exposed in the foot-warmer so that the output shaft of the motor is projected upwardly, the infrared rays heater 3 is arranged near the motor 4 so as to be in the same plane as the motor 4 and the fan 41, attached to the output shaft of the motor 4, is rotated at the upper side of both of the motor 4 and the infrared rays heater 3 in order to make the exothermal body unit compact and blow off the warm-air of the fan 41 through the outer peripheral section of the guard 1. The suction air obtains heat by the infrared rays heater without exception by a relation between the three-dimensional arrangement of the fan and the infrared rays heater and the positions of the suction ports, thereafter, the warm-air is dispersed uniformly throughout the whole outer periphery of the foot-warmer by the fan and, therefore, the temperature distribution in the foot- warmer may be improved. On the other hand, the fan and the infrared rays heater are arranged three-dimensionally, therefore, the exothermal body unit may be completed. |
