PURPOSE:To uniform temperature distribution in a foot warmer unit with a pit by a method wherein a box, equipped with a temperature control device and a fan, is provided in the upper part of a main body provided with a heat generating body and an overheat preventing device. CONSTITUTION:The main body 11 of an electric foot warmer, provided with a heat generating body 14 and an overheat preventing device 15 therein, is arranged in a furnace box 13 at the center of the bottom of an unit 12 with a pit while a box 18, equipped with a fan 16 and a temperature control device 17, is arranged at the center of the ceiling of the foot warmer unit 12 with the pit. The main body 11 of the electric foot warmer and the box 18 are connected electrically while the overheat preventing device 15, the temperature control device 17 and the heat generating body 14 are connected in series. The fan 16 is connected to the overheat preventing device 15 in series while the temperature control device 17 is connected to the heat generating body 14 is parallel. The heat generating body 14 generates heat by the conduction of electricity simultaneously with the rotation of the fan 16 and convection heat, generated by the heat generating body 14, is mixed, therefore, the generation of the variation in temperature in the unit 12 may be prevented and the distribution of heat may be uniformed in the foot warmer unit 12.
